1NuttX Release Notes 2=================== 3 4This file contains are the release notes for the NuttX (and apps) packages 5for every release. The text is just as was written at the time of release 6(with perhaps some corrected typos). Over the course of time, NuttX has 7used several different repositories: CVS, two SVN repositories, and 8currently a GIT repository. Therefore, revision information specific to an 9older repository may not be meaningful today. 10 11To make it easier to track there older versions in the current GIT 12repository, a GIT lightweight tag has been applied for each release. The 13tag name is the release name (for example, the release 6.27 has tag name 14"nuttx-6.27"). 15 16NuttX-0.1.0 17----------- 18 19This is the initial. This initial includes the complete NuttX RTOS 20with support for the Linux user mode simulation and the TI TMS320C5471 21(Arm7) processor. Partial support for the 87C52 is included. 22 23This release has been verified on both the Linux user-mode and C5471 24platforms using the test program under examples/ostest. Test results 25for the C5471 can be found in arch/c5471/doc/test-results.txt. 26 27This tarball contains a complete CVS snapshot from March 9,2007. 28 29NuttX-0.1.1 30----------- 31 32This is the second release of NuttX.

This release is only to roll out 139build changes to better support different SoC's that use the same 140processor architecture. In particular, the two existing ARM architectures, 141c5471 and DM320 were combined into a single ARM directory. This was done 142in preparation for an LPC2148 port that is currently in progress. There 143is NO new functionality or significant bugfixes in this release. 144 145See the ChangeLog for a complete list of changes. 146 147This release has been verified on the Linux user-mode platform 148and the Neuros OSD using the test program under examples/ostest. 149The results of the testing is available in the source tree under 150configs/ntosd-dm320/doc/test-results and under configs/sim/doc/test-results. 151There are no known, critical defects but the project development status 152remains at 'beta' status pending further test and evaluation. 153 154This tarball contains a complete CVS snapshot from April 28, 2007. 155 156NuttX-0.2.5 157------------ 158 159This is the 8th release of NuttX. This release includes: 160 161(1) Several bug fixes 162(2) Initial support for FAT filesystems. Testing has not 163 been exhaustive and some functionality is missing 164 (mkdir, stat, unlink chmod, and rename functionality is 165 not yet implemented). 166(3) Support for the NXP lpc2148 processor is included but 167 is untested as of this writing. The current 168 implementation includes only support for serial console 169 and timer interrupt. 170 171See the ChangeLog for a complete list of changes. 172 173This release has been verified only on the Linux user-mode 174platform. 175 176This tarball contains a complete CVS snapshot from May 19, 1772007. 178 179NuttX-0.2.6 180----------- 181 182This is the 9th release of NuttX. This is primarily a 183bugfix release to correct a number of problems introduced 184with the 0.2.5 release. This release does include some FAT 185filesystem extensions including unlink(), mkdir(), rmdir(), 186rename(), opendir(), closedir(), readdir(), seekdir(), 187telldir(), rewindir(). There are some pending FAT changes 188that did not make it into this release including stat(), 189truncate(), and long file names. 190 191See the ChangeLog for a complete list of changes. 192 193This release has been verified only on the Linux user-mode platform. 194 195This tarball contains a complete CVS snapshot from May 26, 2007. 196 197NuttX-0.2.7 198----------- 199 200This is the 10th release of NuttX. This is primarily a bugfix 201release to correct a number of problems reported to me (thanks 202Didier!). This release does include the final changes complete the 203FAT filesystem logic including stat(), statfs(), and non-standard 204APIs to manage FAT attributes. At present, FAT long file names and 205file truncate() are still not supported. 206 207See the ChangeLog for a complete list of changes. 208 209This release has been verified only on the Linux user-mode platform. 210 211This tarball contains a complete CVS snapshot from June 9, 2007. 212 213NuttX-0.2.8 214----------- 215 216This is the 11th release of NuttX. This release: 217(1) corrects important bugs in opendir() and realloc() 218(2) adds support for environment variables 219(3) adds several new C library interfaces 220(4) extends several example programs 221 222See the ChangeLog for a complete list of changes. 223 224This release has been verified only on the Linux user-mode platform. 225 226This tarball contains a complete CVS snapshot from July 2, 2007. 227 228NuttX-0.3.0 229----------- 230 231This is the 12th release of NuttX. This release includes the initial 232integration of a network subsystem and the uIP TCP/IP stack into NuttX 233(see http://www.sics.se/~adam/uip/index.php/Main_Page). Also included 234is a device driver for the Davicom DM90x0 Ethernet controller. 235 236This integration is very preliminary. Only a small portion of the 237network functionality has been integrated and there are a number of 238open issues (see the TODO file). The network subsystem is pre-alpha 239at this point in time. I expect that it will stabilize and mature 240over the next few releases. 241 242The baseline functionality of NuttX continues to mature and remains at 243post-beta (as long as the network is not used). 244 245See the ChangeLog for a complete list of changes. 246 247This release has been verified only on the Neuros OSD (DM320 ARM9) 248platform using the DM90x0 driver. 249 250This tarball contains a complete CVS snapshot from November 6, 2007. 251 252NuttX-0.3.1 253----------- 254 255This is the 13th release of NuttX and the second release containing 256the integration of a network subsystem and the uIP TCP/IP, UDP, and 257ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). 258 259Many network-related problems have been fixed and the implementation 260has matured significantly. However, the level of network reliability 261is probably still at the pre-alpha or early level. It is sufficiently 262complete that you may begin to perform some network integration and 263is expected to achieve beta level of reliability over the next few 264releases. 265 266The baseline functionality of NuttX continues to mature and remains at 267post-beta (as long as the network is not used). 268 269See the ChangeLog for a complete list of changes. 270 271This release has been verified only on the Neuros OSD (DM320 ARM9) 272platform using the DM90x0 driver. 273 274This tarball contains a complete CVS snapshot from November 19, 2007. 275 276NuttX-0.3.2 277----------- 278 279This is the 14th release of NuttX and the 3rd release containing 280the integration of a network subsystem and the uIP TCP/IP, UDP, and 281ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). 282 283Many network-related problems have been fixed and the implementation 284has matured significantly. This release consists of: 285 286o TCP-related bug-fixes 287o TCP performance improvements 288o Initial UDP integration 289o Initial uIP micro webserver integration 290 291See the ChangeLog for a complete list of changes. 292 293The level of network reliability is at alpha level is expected to 294achieve beta level of reliability over the next few releases. 295 296The baseline functionality of NuttX continues to mature and remains at 297post-beta. 298 299This release has been verified only on the Neuros OSD (DM320 ARM9) 300platform using the DM90x0 driver. 301 302This tarball contains a complete CVS snapshot from November 23, 2007. 303 304NuttX-0.3.3 305----------- 306 307This is the 15th release of NuttX and the 4th release containing 308the integration of a network subsystem and the uIP TCP/IP, UDP, and 309ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). 310 311Many network-related problems have been fixed and the implementation 312has matured significantly. This release consists of: 313 314o TCP-related bug-fixes for disconnecting sockets 315o Correction of some TCP read-ahead logic 316o TCP performance improvements 317o Misc. additions and cleanup (See the ChangeLog for a complete list of 318 changes). 319 320The level of network reliability is at an early beta release level. The 321baseline functionality of NuttX continues to mature and remains at 322post-beta. Open network-related issues include only: 323 324o Some minor unimplemented BSD socket functionality, 325o Thread safety issues: the same socket cannot be used concurrently on 326 different threads. 327o Pending design changes necessary to support multiple network interfaces. 328o IPv6 support is incomplete. 329 330This release has been verified only on the Neuros OSD (DM320 ARM9) 331platform using the DM90x0 driver. Any feedback for improving the network 332reliability/performance would be greatly appreciated. 333 334This tarball contains a complete CVS snapshot from November 28, 2007. 335 336NuttX-0.3.4 337----------- 338 339This is the 16th release of NuttX and the 5th release containing 340the integration of a network subsystem and the uIP TCP/IP, UDP, and 341ICMP stacks into NuttX (see http://www.sics.se/~adam/uip/index.php/Main_Page). 342 343This release is primarily a bug-fix release. New features include 344only: 345 346o TELNET front-end to NSH, 347o DHCPC server functionality, and 348o C5471 Ethernet driver. 349 350Numerous network related problems were fixed related to DHCPC, UDP 351input processing, UDP broadcast, send timeouts, and bad compilation when 352uIP is compiled at high levels of optimization. 353 354The level of network reliability is at a strong beta release level. The 355baseline functionality of NuttX continues to mature and remains at 356post-beta or production level. 357 358Parts of this release were verified only on the Neuros OSD (DM320 ARM9) 359platform using the DM90x0 Ethernet driver and other parts on the Spectrum 360Digital C5471 EVM using the C5471 Ethernet driver. Any feedback about bugs 361or suggestions for improving the network reliability/performance would be 362greatly appreciated. 363 364This tarball contains a complete CVS snapshot from December 10, 2007. 365 366NuttX-0.3.5 367----------- 368 369This is the 17th release of NuttX this release is primarily a bug-fix 370release and intended to synchronize with the current CVS contents. See 371the ChangeLog for a detailed list of changes and fixes. 372 373This release were verified only on the Spectrum Digital C5471 EVM using 374the C5471 Ethernet driver. Any feedback about bugs or suggestions for 375improvement would be greatly appreciated. 376 377This tarball contains a complete CVS snapshot from December 18, 2007. 378 379NuttX-0.3.6 380----------- 381 382This is the 18th release of NuttX. This release contains on a few 383changes. The primary purpose of this release is to synchronize with 384the release of the pascal-0.1.0 add-on package. 385 386This release of NuttX includes the following changes: 387 388* Fixes for use with SDCC compiler 389* Added a simulated z80 target (arch/z80) 390* Fix deadlock errors when using stdio but with no buffering 391* Add support for the add-on Pascal P-Code interpreter (pcode/) 392 (see the pascal-0.1.0 package) 393 394This release were verified only on the simulated Z80 and host 395simulation targets. As usual, any feedback about bugs or suggestions 396for improvement would be greatly appreciated. 397 398This tarball contains a complete CVS snapshot from January 6, 2007. 399 400==== 401 402There was an error in the initial 0.3.6 release that prevented 403a successful build unless the Pascal add-on was present. The 404tarball was patched to include the fix. Make sure that you download 405the nuttx-0.3.6.1.tar.gz version to avoid this problem. 406 407NuttX-0.3.7 408----------- 409 410This is the 19th release of NuttX. This release includes the 411preliminary port of NuttX to the ZiLOG z16f 16-bit microcontroller. 412This port was verified using the ZiLOG z16f2800100zcog Development 413and the ZiLOG ZDS-II toolchain. See http://www.zilog.com for 414further information. 415 416I emphasize that this is a preliminary release of the z16f port and 417is only alpha or, perhaps, pre-alpha quality as of this writing. 418There are a list of known issues in the TODO file in the root of 419the NuttX directory. The overall quality of NuttX (excluding the 420z16f port) continues to improve beyond the late beta level. 421 422The z16f port required numerous changes to NuttX to handle: 423 424* NEAR and FAR addressing, and 425* Use of a Windows native toolchain in a Cygwin build environment. 426 427In addition to the z16f port, at least one very critical bug was 428found and corrected in NuttX: The thread-specific errno value of one 429task was being randomly trashed when a different thread exited. 430 431This release were verified on the ZiLOG z16f2800100zcog, Neuros OSD 432(ARM9), and the simulation platforms. As usual, any feedback about bugs 433or suggestions for improvement would be greatly appreciated. 434 435This tarball contains a complete CVS snapshot from January 31, 2008. 436 437NuttX-0.3.8 438----------- 439 440This is the 20th release of NuttX.

The form of the interface was inspired by the Linux Gadget APIs. 627 628At present USB device controller drivers are included for: 629 * The NXP LPC214x. This driver has been verified and is an early alpha 630 stage in quality. 631 * TI DM320. Coding for this driver is complete but it is completely 632 untested as of this release. 633 634A controller-independent class driver is also included for: 635 * USB serial class device driver (emulates the Prolific PL2303 636 serial-to-USB adapter). This driver has only been verified with 637 the Linux host PL2303 driver. 638 639Other new features include: 640 * Add an option to set aside a separate stack for interrupt 641 handling (ARM only). This is useful when memory is constrained, 642 there are multiple tasks, and the interrupt stack requirement 643 is high (as when USB is enabled). 644 645A few bugs were also fixed: 646 * Fixed the frequency of system timer interrupts in the NXP LPC214x port 647 (off by 20x in nuttx-0.3.15) 648 * Fixed serial driver bugs related to (1) open counts and (2) recognizing 649 O_NONBLOCK on read. 650 * Fixed an error in read(); it was not setting the errno on errors returned 651 from the driver. 652 653These changes were verified only on the mcu123.com NXP LPC2148 board 654using with a Linux host. Please report any errors to me. 655 656This tarball contains a complete CVS snapshot from October 10, 2008. 657 658UPDATE 659------ 660This release does not build for the ARM target when USB is disabled. 661Here is the fix: 662 663Index: arch/arm/src/common/up_internal.h 664=================================================================== 665RCS file: /cvsroot/nuttx/nuttx/arch/arm/src/common/up_internal.h,v 666retrieving revision 1.13 667diff -u -r1.13 up_internal.h 668--- arch/arm/src/common/up_internal.h 6 Oct 2008 16:20:52 -0000 1.13 669+++ arch/arm/src/common/up_internal.h 13 Oct 2008 20:48:21 -0000 670@@ -200,7 +200,8 @@ 671 extern void up_usbinitialize(void); 672 extern void up_usbuninitialize(void); 673 #else 674-# define up_netinitialize() 675+# define up_usbinitialize() 676+# define up_usbuninitialize() 677 #endif 678 679 #endif /* __ASSEMBLY__ */ 680 681NuttX-0.3.17 682------------ 683 684This is the 29th release of NuttX. This release includes the 685additional support for USB in NuttX. The following new features 686were added: 687 688* Added support for SPI-based MMC/SD cards (with an SPI driver 689 for the NXP LPC214x). 690* Added USB storage class device side driver (BBB) 691* Added an example that demonstrates the USB storage class by 692 exporting the SPI based MMC/SD card on the NXP LPC214x. 693 694This is an early alpha release of these drivers. At present they 695only work with debug features enabled so there are probably some 696race conditions that occur only with debug features disabled. 697(Anyone out there with a USB analyzer? I would love to know what 698is happening.) 699 700Several important bugs were also fixed in the FAT file system, USB 701serial driver and NXP LPC214x USB controller driver. (See the ChangeLog 702for details.) 703 704These changes were verified only on the mcu123.com NXP LPC2148 board 705using a Linux development environment. USB testing was performed 706using both a Linux host and a WinXP host. Please report any errors 707to me. 708 709This tarball contains a complete CVS snapshot from October 28, 2008. 710 711NuttX-0.3.18 712------------ 713 714This is the 30th release of NuttX. This release includes two 715partially completed ports, several new features, and a couple of 716important bug fixes. The two partially completed ports are: 717 718 * The STMicro STR71x processor and configuration for the Olimex 719 STR-P711 board. 720 * The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board 721 722Progress on these ports is stalled (as detailed in the ChangeLog). 723 724The new features focus primarily on management of block devices and 725extensions of the NuttShell (NSH). These include: 726 727 * A loop device that converts a file into a block device. 728 * A block to character (BCH) driver that allow access a block device as 729 if it were character device. 730 * Added strcasecmp() and strncasecmp() libc functions. 731 * Added the 'dd' and 'losetup' commands to NSH. These commands 732 (along with mkfatfs and mount), give good management of filesystems 733 on the target. 734 735Several bugs were fixed, the most important of which are: 736 737 * Fixed a race condition workaround delay in LPC214X SPI logic. 738 This was also the cause of some bad MMC/SD performance on that 739 platform. 740 741 * Fixed a recently introduced FAT file system problem: It would 742 mount a (invalid) FAT file system even if the medium is not formatted! 743 744 * Corrected two other important errors in the FAT lseek() implementation: 745 1 - The sectors-per-cluster value was being reset to "1". 746 2 - Important lseek logic was omitted when the seek position was zero. 747 748The FAT filesystem has had many bugs fixed in it and, I think, is 749now maturing and becoming stable. 750 751These changes were verified only on the mcu123.com NXP LPC2148 752board, the Hitachi SH1_LCEVB1 board, and the Linux simulator, all 753using a Linux development environment. Please report any errors 754to me. 755 756This tarball contains a complete CVS snapshot from November 16, 2008. 757 758NuttX-0.3.19 759------------ 760 761This is the 31st release of NuttX. This release includes the 762following new feature: 763 764 * Add poll() and select() APIs that may be used to monitor for 765 data availability on character devices or TCP/IP sockets. 766 * Implemented support TCP/IP connection backlog. This allows 767 select() to wake-up on new connections to a listener socket. 768 * Added definition of a framebuffer driver and implement framebuffer 769 drivers for the simulated platform and the TI DM320 (untested 770 as of the initial check-in). 771 * Partially developed a graphics framework based on the framebuffer 772 drivers, however, this will not be ready for use for a few more 773 releases. Currently this includes only a few color conversion 774 routines and some rasterizing functions. A tiny windowing system 775 is under development but not ready for check-in yet. 776 * Added support for fixed precision math. 777 * Added support for outgoing multicast packets. 778 779Several bugs were fixed, the most important of which are: 780 781 * Fixed an important bug in the TCP/IP buffering logic. When 782 TCP/IP read-ahead is enabled and not recv() is in-place when a 783 TCP/IP packet is received, the packet is placed into a read-ahead 784 buffer. However, the old contents of the read-ahead buffer 785 were not being cleared and old data would contaminate the newly 786 received buffer. 787 788 * Changed the behavior of the serial driver read. It now returns 789 data as it is available rather than waiting for the full requested 790 read size. This makes functions like fgetc() work much more 791 smoothly. 792 793These changes were verified only on the Neuros OSD (ARM9) using a 794Linux development environment. Please report any errors to me. 795 796This tarball contains a complete CVS snapshot from November 26, 2008. 797 798NuttX-0.4.0 799----------- 800 801This is the 32nd release of NuttX. This release adds graphics 802support and a tiny windowing subsystem. That new graphics subsystem 803is documented at http://nuttx.sourceforge.net/NXGraphicsSubsystem.html. 804No other substantial changes were made. 805 806These changes were verified only on the NuttX simulation platform 807with X11 windows simulating a device framebuffer. Please report any 808errors to me. 809 810The version number was bumped up to 0.4.0 in part to reflect the 811new graphics subsystem, but also to recognize the NuttX is approaching 812complete functionality. In the 0.3.x versions, network support was 813added, Pascal P-code runtime support was added, FAT and ROMFS 814filesystems were added, MMC/SD and USB device support were added. 815There were also numerous extensions to the NuttShell, NuttX APIs, 816and architecture ports. 817 818This tarball contains a complete CVS snapshot from December 6, 2008. 819 820NuttX-0.4.1 821----------- 822 823This is the 33rd release of NuttX. This is a minor bugfix release. 824The primary reason for this release is to correct numerous build 825errors that have accumulated for the ZiLOG ZDS-II based targets. 826All ZDS-II targets now build correctly (but have not been re-tested). 827In addition to platform-specific build failures, this release also 828adds the following features which were not tested as of the time 829of the release: 830 831 * Board support for the ZiLog ez80Acclaim! ez80f910200zco Development Kit 832 * ZiLOG eZ80F91 EMAC driver 833 834These changes were verified only on the NuttX simulation platform. 835Please report any errors to me. 836 837This tarball contains a complete CVS snapshot from February 6, 2009. 838 839NuttX-0.4.2 840----------- 841 842This is the 34th release of NuttX. This release adds no new OS 843features but does include support for two new architectures: 844 845 * ez80Acclaim! Basic support has been integrated and verified 846 for the ez80f910200zcog-d board (eZ80F91-based). That basic 847 support includes timer interrupts and serial console. Ongoing 848 work includes an EMAC driver that should be integrated for the 849 next release nuttx-0.4.2. eZ80Acclaim! support has been in the 850 code base for some time, but has only just been integrated due 851 to toolchain issues. 852 853 * Renesas M16C/20. Support for the Renesas SKP16C20 board has 854 been included in the NuttX source tree. However, as the 855 eZ80Acclaim!, testing and integration of that port is stalled 856 due to toolchain issues. 857 858These changes were verified only on the ZiLOG eZ80910200zcog-d 859board. Please report any errors to me. 860 861This tarball contains a complete CVS snapshot from February 28, 2009. 862 863NuttX-0.4.3 864----------- 865 866This is the 35th release of NuttX. This release one important new 867OS feature and corrects and extends the eZ80 port: 868 869 * Priority Inheritance. The basic NuttX waiting logic was extended 870 to support priority inheritance. See the NuttX User Manual for 871 further information: 872 http://www.nuttx.org/NuttxUserGuide.html#priorityinheritance. 873 874 * ez80Acclaim! Corrected several critical, show-stopping bugs on that 875 platform including: 876 - Errors in the serial driver interrupts. 877 - An error in the eZ80 table. 878 * eZ80Acclaim!: Completed integration of the eZ80F91 EMAC driver. 879 880These changes were verified only on the ZiLOG eZ80910200zcog-d board 881and on Cygwin-based simulation platform in various configurations. 882Please report any errors to me. 883 884This tarball contains a complete CVS snapshot from March 13, 2009. 885 886NuttX-0.4.4 887----------- 888 889This is the 36th release of NuttX. This release focuses on bugfixes 890and extending and verifying certain networking features. 891 892 * Important bugs were fixed in NSH, UDP checksum calculation, UDP 893 bind() behavior for port==0, the eZ80Acclaim! EMAC driver, Z80 894 interrupt handling, and in the C libraries. 895 896 * Testing was extended to further verify the tiny webserver, 897 DHCPD, wget(), and sendmail. 898 899See the Changelog for a detailed description of these changes. 900 901These changes were verified only on the ZiLOG eZ80910200zcog-d board 902using the ZDS-II toolchain in Cygwin-based environment. Please 903report any errors to me. 904 905This tarball contains a complete CVS snapshot from March 29, 2009. 906 907NuttX-0.4.5 908----------- 909 910This is the 37th release of NuttX. This release focuses on a few new features. 911 912 * The basic port for the Freescale ARM920T i.MX1 processor on the 913 Freescale MX1ADS board. Coding is complete for this port, but 914 it is has not yet fully integrated 915 * Extended I2C and SPI interface definitions 916 * Add basic support for C++ applications. Very simple C++ 917 applications can now be built against NuttX without any external 918 libraries. At present, only the most primitive C++ programs 919 are supported, but it is hoped that this support will be extended 920 in future releases. 921 922See the Changelog for a detailed description of these changes. 923 924This tarball contains a complete CVS snapshot from April 19, 2009. 925 926NuttX-0.4.6 927----------- 928 929This is the 38th release of NuttX. The release features support 930for the Micromint Eagle-100 development board. This board is based 931around, the Luminary LM3S6918 MCU. This is the first ARM Cortex-M3 932architecture supported by Nuttx. This initial, basic port includes 933timer and serial console with configurations to execute the NuttX 934OS test and to run the NuttShell (NSH). Work is still underway on 935this port and current plans are to have I2C, SSI, MMC/SD, and 936Ethernet driver in the 0.4.7 release. 937 938Additional work was done on the MXADS i.MX1 port, however, that 939work has been set aside until I complete work on the Eagle-100 (I 940also need to come up with a 3V power supply). 941 942Other changes in this release include: Extensions to the SPI interface 943definition in order to handle 9-bit interfaces to displays. Several 944bugs were fixed (see the ChangeLog for a complete list of changes). 945 946This tarball contains a complete CVS snapshot from May 19, 2009. 947 948NuttX-0.4.7 949----------- 950 951This is the 39th release of NuttX. This release focuses on cleaning 952up and extending the Eagle100/LM3S6918 port released in nuttx-0.4.6 953and on improved MMC/SD support. New features include: 954 955 * Improved reliably and additional drivers for the Eagle-100 board 956 (LM3S6918 ARM Cortex-M3). Additional drivers include Ethernet, 957 SSI, and support for the on-board LEDs and microSD cards. 958 959 * The SPI-based MMC/SD driver was extended to support SDHC Version 960 2.xx cards. 961 962In addition, this release includes several important bugfixes for 963the LM3S6918, the LPC2148, the SPI-based MMC/SD driver, and to 964FAT32. See the ChangeLog for details of these bugfixes. 965 966This tarball contains a complete CVS snapshot from May 29, 2009. 967 968NuttX-0.4.8 969----------- 970 971This is the 40th release of NuttX. This release adds: 972 973 * Support for the Olimex STRP711 board. That board is based on 974 the STMicro STR711 MCU (ARM7TDMI). Integration is complete on 975 the basic port (boot logic, system time, serial console). Two 976 configurations have been verified: (1) The board boots and 977 passes the OS test with console output visible on UART0, and 978 the NuttShell (NSH) is fully functional with interrupt driven 979 serial console. An SPI driver is available but untested (because 980 the Olimex card slot appears to accept only MMC cards; I have 981 only SD cards). Additional needed: USB and driver, MMC 982 integration. 983 984 * Support for the CodeSourcery and devkitARM Windows-native GNU 985 toolchains. Makefiles have been modified for the LM3S6918, 986 LPC2148, and STR711 to support these toolchains under Cygwin. 987 988This tarball contains a complete CVS snapshot from June 13, 2009. 989 990NuttX-0.4.9 991----------- 992 993This is the 41st release of NuttX. This release adds: 994 995 * Support for a new binary format call NXFLAT that can be used to 996 execute separately linked programs in place in a file system. 997 See http://www.nuttx.org/NuttXNxFlat.html. 998 999 * Several important bugs were files related to networking and ROMFS. 1000 See the ChangeLog for a complete list. 1001 1002This tarball contains a complete CVS snapshot from June 26, 2009. 1003 1004NuttX-0.4.10 1005----------- 1006 1007This is the 42nd release of NuttX. This released focused on the 1008port of Jeff Poskanzer's THTTPD HTTP server (see 1009http://acme.com/software/thttpd/). As of the 0.4.10 release, that 1010port is still not fully complete and functional. However, numerous 1011related bug-fixes and functional additions for THTTPD were added: 1012 1013 * Several new standard C-library functions (fileno, strstr, 1014 strpbrk, fcntl). 1015 * Improved and extended timing APIs (mktime, gmtime, gmtime_r, 1016 gettimeofday, localtime, localtime_r, and strftime) 1017 * Networking enhancements: recvfrom() and accept() now work with 1018 non-blocking sockets. 1019 * NXFLAT extensions (exec) 1020 * Pattern matching logic. 1021 * And miscellaneous bug fixes (see the ChangeLog for details). 1022 1023This tarball contains a complete CVS snapshot from August 8, 2009. 1024 1025NuttX-0.4.11 1026------------ 1027 1028This is the 43rd release of NuttX. This release of NuttX incorporates 1029the verified port of Jeff Poskanzer's THTTPD HTTP server (see 1030http://acme.com/software/thttpd/). Many of the key features of 1031THTTPD have been tested on the Micromint Eagle-100 development board 1032(Cortex-M3). These tests verify: 1033 1034 * Serving of files from any file system 1035 * Execution of CGI executable. This release supports execution 1036 of NXFLAT executables on a ROMFS file system 1037 (http://www.nuttx.org/NuttXNxFlat.html) 1038 1039A standard CGI interface is used: Information is pasted to the CGI 1040program via POST commands and via environment variables. CGI socket 1041I/O is redirected to stdin and stdout so that the CGI program only 1042need to printf() to send its content back to the HTTP client. 1043 1044Another value to this THTTPD integration effort has been that THTTPD 1045has provided a very good test bed for finding NuttX networking bugs. 1046Several very critical networking bugs have been fixed with this 10470.4.11 release (see the ChangeLog for details). Networking throughput 1048has also been greatly improved. Anyone using NuttX networking 1049should consider upgrading to this release. 1050 1051This tarball contains a complete CVS snapshot from September 16, 2009 1052 1053NuttX-0.4.12 1054------------ 1055 1056This is the 44th release of NuttX. This release adds basic support 1057for the STMicro STM32, Cortex-M3 MCU. The specific port is to the 1058STMicro STM3210E-EVAL development board based around the STM32F103ZET6 1059MCU. Some highlights of this port: 1060 1061 * This basic port includes boot-up logic, interrupt driven serial 1062 console, and system timer interrupts. 1063 * Includes a basic STMicro RIDE7 project that can be used to 1064 perform basic STM32 board bring-up (due to RIDE7 size limitations, 1065 it cannot be used for the full NuttX bring-up). 1066 * Working, Tested Configurations: the NuttX OS test and the 1067 NuttShell (NSH) example. 1068 1069This basic STM32 port will be extended in the 0.4.13 NuttX release. 1070Functionality needed for complete STM32 support includes: USB 1071device driver, LCD driver and NX bringup on the development board's 1072display and MicroSD support. An SPI driver and a DMA support was 1073included in this 0.4.12 release, but is not yet tested. 1074 1075This tarball contains a complete CVS snapshot from October 17, 2009 1076 1077NuttX-0.4.13 1078------------ 1079 1080This is the 45th release of NuttX. The release extends the support 1081for the STMicro STM32 microcontroller. Minimal support for the 1082STM3210E-EVAL development board based around the STM32F103ZET6 MCU 1083was released in NuttX-0.4.12. This release adds: 1084 1085 * A simple interface definition to support some FLASH, EEPROM, 1086 NVRAM, etc. devices. 1087 * Verified SPI operation using driver for SPI based FLASH parts 1088 M25P64 and M25P128. 1089 * Improved Cortex-M3 context switching. This should improve 1090 context switching performance be 2x in certain cases. 1091 * Added a USB device-side driver for the STM32. This is an early 1092 release of a very complex driver; some bugs are expected. 1093 * The USB driver has been verified against the USB serial device 1094 class driver. There is at least one known outstanding issue 1095 (see the full bug description in the TODO list). 1096 1097This release also corrects some important bugs in the early STM32 release: 1098 1099 * Fixed several errors the prevented operation of NuttX on an 1100 STM32 development board using USART2 as the serial console. 1101 * Fixed and optimization-dependent race condition in the clock 1102 initialization. 1103 * Fixed a critical bug in the interrupt control logic that could 1104 cause interrupt operations to failed used for interrupts in a 1105 certain range. 1106 1107This tarball contains a complete CVS snapshot from November 4, 2009 1108 1109NuttX-4.14 1110---------- 1111 1112This is the 46th release of NuttX. The release extends the support 1113for the STMicro STM32 microcontroller. Minimal support for the 1114STM3210E-EVAL development board based around the STM32F103ZET6 MCU 1115was released in NuttX-0.4.12 and extended in Nuttx-0.4.13 to include 1116initial USB support. This completes the STM32F103ZET6 and adds: 1117 1118New Generic RTOS Features: 1119 1120 * Added generic support that can be included in any block driver 1121 to provide read-ahead buffering and write buffering for improved 1122 driver performance. 1123 * Added a generic worker thread that can used to defer processing 1124 from an interrupt to a task. 1125 * Defined a generic SD/SDIO interface can can be bound to a MMC/SD 1126 or SDIO driver to provide SDIO support. 1127 * Implemented a an SDIO-based MMC/SD driver using this new SDIO 1128 interface. 1129 1130New STM32 Features: 1131 1132 * Add support to configure an STM32 input GPIO to generate an 1133 EXTI interrupt. 1134 * Added support for buttons on the STM3210E-EVAL board. 1135 * Implemented an STM32 version of the common the SDIO interface. 1136 * Added a configuration to exercise the STM32 with the USB mass 1137 storage device class example. 1138 1139This release also corrects some important bugs in the early STM32 release: 1140 1141 * Correct error handling in the mount() logic. 1142 * Fixed several STM32 DMA-related issues. Integrated and debugged 1143 STM32 DMA functionality that was added in 0.4.12. 1144 * Fixed several bugs in the STM32 USB device-side driver. 1145 1146NOTE: This version, 4.14, is equivalent to what would have been 1147called 0.4.14 to follow 0.4.13. The zero has been eliminated from 1148the front of the version number to avoid confusion about the state 1149of development: Some have interpreted the leading zero to mean 1150that the code is in some way unstable. That was not the intent. 1151Beginning in January 2010, I will switch to the 2010.nn versioning 1152as many others have done to avoid such confusion. 1153 1154This tarball contains a complete CVS snapshot from December 2, 2009 1155 1156NuttX-5.0 1157--------- 1158 1159This is 47th release of NuttX and the successor to nuttx-4.14. This 1160major revision number has been incremented to indicate that an 1161incompatibility with previous nuttx releases has been introduced. 1162This version adopts standard fixed width integer names as specified 1163by the ANSI C99 standard. The core logic of NuttX is older than 1164that standard and did not conform to it. 1165 1166If you have applications running on NuttX-4.14, those applications 1167should continue to build and execute without problem on NuttX-5.0. 1168However, if you have device drivers or other OS-internal logic, you 1169will probably have to make some minor changes to your code to use 1170this version. Below is a summary of those changes: 1171 1172 * If you include sys/types.h to get the non-standard, fixed width 1173 integer types (uint32, uint16, ubyte, etc.), that is no longer 1174 necessary. 1175 * Instead, you will need to include stdint.h where the new fixed 1176 width integer types are defined (uint32_t, uint16_t, uint8_t, etc). 1177 * You will have to change all occurrences of the following types: 1178 1179 uint32 -> uint32_t 1180 uint16 -> uint16_t 1181 ubyte -> uint8_t 1182 uint8 -> uint8_t 1183 sint32 -> int32_t 1184 sint16 -> int16_t 1185 sint8 -> int8_t 1186 1187 * In addition, the non-standard type 'boolean' must replaced with 1188 the standard type 'bool'. The type definition for 'bool' is in 1189 stdbool.h 1190 1191This change in typing caused small changes to many, many files. It 1192was verified that all configurations in the release still build 1193correctly (other than the SDCC-based configurations). Regression 1194testing was performed on a few configurations, but it is possible 1195that minor build issues still exist. (If you encounter any, please 1196let me know and I will help you to fix them.) 1197 1198In the course of the regression testing, several important bugs 1199unrelated to the type changes were found and corrected. 1200 1201 * Fixed an important error in the RX FIFO handling logic of the 1202 LM3S6918 Ethernet driver. 1203 * Corrected the handling of TCP sequence numbers in the TCP stack. 1204 * And other less important bugs as detailed in the ChangeLog. 1205 1206The primary focus of this release was standards compatibility, but 1207a few new features were added including a (1) Flash Translation 1208Layer (FTL) that will support filesystems on a FLASH device and (2) 1209partial ports for the STM32F107VC and HCS12 C9S12NE64 MCUs. Those 1210ports are very incomplete as of this writing. 1211 1212This tarball contains a complete CVS snapshot from December 21, 2009 1213 1214NuttX-5.1 1215--------- 1216 1217This is the 48th release of NuttX. This release adds support for 1218two new MCU architectures in various states of development: 1219 1220* AT91SAM3U (http://www.atmel.com/products/at91/sam3landing.asp?family_id=605) 1221 1222 This release adds support for the SAM3U-EK development board with 1223 the AT91SAM3U4E MCU 1224 (http://www.atmel.com/dyn/products/product_card_mcu.asp?part_id=4562). 1225 As with most NuttX architecture releases, the release will be 1226 rolled out in two parts: A basic port and an extended port. 1227 1228 NuttX-5.1 includes the basic port for the SAM3U-EK board. This 1229 release passes the NuttX OS test and is proven to have a valid 1230 OS implementation. It supports the basic boot-up, serial console 1231 and timer interrupts. A configuration to support the NuttShell 1232 is also included. 1233 1234 The extended port will also include support for SDIO-based SD 1235 cards and USB device (and possible LCD support). These extensions 1236 may or may not happen by the Nuttx 5.2 release as my plate is 1237 kind of full now. 1238 1239* LPC3131 (http://ics.nxp.com/products/lpc3000/lpc313x.lpc314x.lpc315x/) 1240 1241 This release also adds the complete implementation of the basic 1242 port for the NXP LPC3131 MCU on the Embedded Artists EA3131 board 1243 (http://www.embeddedartists.com/products/kits/lpc3131_kit.php). 1244 That port, unfortunately has stalled due to tools issues. Those 1245 tool issues have been resolved and I am confident that the verified 1246 basic port will be available in NuttX-5.2. 1247 1248 The extended release will follow and should include SDIO-based 1249 SD card support and device USB. 1250 1251A few additional features and bugfixes of a minor nature were also 1252incorporated as detailed in the ChangeLog. 1253 1254NuttX-5.2 1255--------- 1256 1257This is the 49th release of NuttX. This release completes the 1258verification of the basic port for the NXP LPC3131 MCU on the 1259Embedded Artists EA3131 board 1260(http://www.embeddedartists.com/products/kits/lpc3131_kit.php). 1261This basic port includes basic boot-up, serial console, and timer 1262interrupts. This port has been verified on the using the NuttX OS 1263test and includes a working implementation of the NuttShell (NSH). 1264 1265An extended release will follow and should include SDIO-based SD 1266card support and device USB. 1267 1268NuttX-5.3 1269--------- 1270 1271This is the 50th release of NuttX. This release support for one new 1272architecture: 1273 1274 * A basic port for the NXP LPC2378 MCU on the Olimex-LPC2378 1275 development board was contributed by Rommel Marcelo. 1276 1277And extensions to two existing architectures: 1278 1279 * David Hewson contributed a dual-speed (full/high) USB device-side 1280 driver for the NXP LPC3131 on the Embedded Artists EA3131 1281 development board. 1282 1283 * A DMA driver and a high speed MCI driver for the Atmel AT91SAM3U 1284 are included (but not fully tested in this release). 1285 1286Two important bugfix was also included: 1287 1288 * An important fix to the USB mass storage driver was contributed 1289 by David Hewson. 1290 * A serious error in the AT91SAM3U PIO handling was fixed. 1291 1292NuttX-5.4 1293--------- 1294 1295This is the 51st release of NuttX. This release includes one new, 1296important extension to th NX graphics system (See 1297http://www.nuttx.org/NXGraphicsSubsystem.html). 1298 1299NX was develop a couple years back on hardware that supported only 1300framebuffer devices, that is, video hardware with video memory 1301directly converts the memory content to video. However, most MCUs 1302that NuttX focuses on do not support such video memory; rather, 1303that typically only support LCDs via parallel or serial interfaces. 1304 1305This release of NuttX extends NX so that now renders directly to 1306the LCD device via its serial or parallel interface. No in-memory 1307copy of the screen memory need be maintained so this solution should 1308also work in MCUs with very limited SRAM. 1309 1310This initial release of this feature includes the verified NX 1311extensions plus a driver for the HX8347, 16-bit parallel LCD. This 1312LCD supports 16-bit RGB (5:6:5). 1313 1314NuttX-5.5 1315--------- 1316 1317This is the 52nd release of NuttX. This release includes one new 1318port, some new drivers and some important bugfixes: 1319 1320 * NuttX was ported to the Luminary/TI LM3S6965 Ethernet Evaluation 1321 Kit. At present, that port includes an OS test configuration 1322 and a NuttShell (NSH) configuration with Telnet support. 1323 1324 MMC/SD and Networking support are provided but not thoroughly 1325 verified in this release: Current development efforts are focused 1326 on porting the NuttX window system (NX) to work with the 1327 Evaluation Kits OLED display. 1328 1329 * A NuttX Ethernet driver for the Microchip ENC28J60 SPI Ethernet 1330 chip is available in the source tree (but has not yet been fully 1331 verified because I haven't properly connected it to hardware 1332 yet). 1333 1334 * The Olimex STR-P711 NuttX port was extended to support the 1335 ENC28J60 and some new networking configurations were added. 1336 The ENC28J60 has not been tested on the STR-P711, however, 1337 because of hardware issues (I don't think the USB powered board 1338 provides enough power for the ENC28J60 and I don't have the 1339 right wall wart yet). 1340 1341 Along the way, external interrupt support (XTI) was added to 1342 the STMicro STR-P711 port and some important bugs were fixed 1343 in the STR-P711 SPI driver. 1344 1345 * Added (optional) floating point support for printf(). 1346 (Contributed by Yolande Cates.) 1347 1348 * Corrected an important UDP reference counting error. It was 1349 not a serious error, but it trigger an assertion was IS a serious 1350 error. 1351 1352NuttX-5.6 1353--------- 1354 1355This is the 53rd release of NuttX. This release includes one several 1356new drivers for existing NuttX ports: 1357 1358 * This port adds support for the RiT displays P14201 4-bpp, 1359 greyscale OLED. 4-bpp greyscale support was integrated into 1360 the NX graphics sub-system and verified using the TI/Luminary 1361 LP3S6965 Ethernet Evaluation Kit. 1362 1363 * The M25Px driver was extended for the M24P1 FLASH part (see NOTE). 1364 1365 * An I2C driver and (basic) SPI driver were added for the NXP 1366 LPC313x port. The I2C interface definition was extended to 1367 efficiently handle multiple I2C transfers. 1368 (Contributed by David Hewson.) 1369 1370As well as a few, important USB-related bugfixes (See the ChangeLog 1371for details). 1372 1373This release also includes the beginnings of a port for the NXP 1374LPC1768 MCU. However, it is too early for that port to be useful 1375(stay tuned for a future announce of the availability of the LPC1768 1376port). 1377 1378NuttX-5.7 1379--------- 1380 1381This is the 54th release of NuttX. This release adds basic support 1382for one new ARM Cortex-M3 architecture: 1383 1384 * Added support for NXP LPC1768 MCU as provided on the Nucleus 1385 2G board from 2G Engineering (http://www.2g-eng.com). 1386 * Some initial files for the LPC17xx family were released in NuttX 1387 5.6, but the first functional release for the NXP LPC1768/Nucleus2G 1388 occurred with NuttX 5.7. 1389 * That initial basic release included timer interrupts and a 1390 serial console and was verified using the NuttX OS test. 1391 * That release includes a verified NuttShell (NSH) configuration 1392 (see the http://www.nuttx.org/NuttShell.html). 1393 * Also included are unverified SPI and USB device drivers. 1394 1395Further efforts include: 1396 (1) development of a DMA support library 1397 (2) SPI-based MMC/SD support 1398 (3) verification of the USB driver 1399 1400Watch for announcement of the completed LPC1768 port expected in 1401NuttX-5.8. 1402 1403NuttX-5.8 1404--------- 1405 1406This is the 55th release of NuttX. This includes several important 1407bugfixes: 1408 1409 * Corrects some interrupt vectoring for the TI/Stellarix LM3S 1410 port 1411 * Correct initialization logic for NXP LPC17xxx NuttX ports: 1412 Power was not being provided to the GPIO module! 1413 * Corrected (but did not verify) implementation of the optional 1414 interrupt stack feature (all Cortex M3 architectures). 1415 * Correct a HardFault in the LPC17xx SSP driver. 1416 1417Additional minor fixes are also included as detailed in the ChangeLog. 1418 1419Several new features have been fully developed and included in this 1420release, but full verification of most of these new features has 1421been blocked for a variety of issues: 1422 1423 * Added microSD support for the NuttShell (NSH) configuration in 1424 the Nucleus2G LPC1768 port. For reasons that have not yet been 1425 determined, I have not successfully accessed the microSD card 1426 as of this writing. 1427 * Two USB configurations were also added for the Nucleus2G board: 1428 One to support the USB serial device and one for the USB mass 1429 storage device. Some testing of the USB driver was performed, 1430 but full verification is stalled for an OTG style USB cable. 1431 * LEDs now work correctly on the Nucleus2G LPC1768 board. 1432 * The NuttX/uIP networking subsystem now supports IGMPv2 client. 1433 IGMP (Internet Group Multicast Protocol) network "appliances" 1434 to join into multicast groups. Outbound traffic to enter and 1435 leave multicast groups has been verified, but full verification 1436 will require a switch capable of multicast. Issues associated 1437 with the receipt of multicast packets are likely. 1438 1439NuttX-5.9 1440--------- 1441 1442This is the 56th release of NuttX. This release is difficult to 1443categorize; NuttX-5.9 was really released because there were too 1444many changes accumulating in CVS -- a few important, some unfinished 1445implementations, and a couple of important bugfixes. 1446 1447 * By far biggest change in this release is the complete implementation 1448 of on-demand paging support. This feature will allow you to 1449 execute large programs on a mass storage device (such as SPI 1450 FLASH) in a small RAM. All of the core on-demand paging logic 1451 was completed (see http://www.nuttx.org/NuttXDemandPaging.html) 1452 and support was implemented for the ARM-9 family. A test 1453 configuration is in place for the NXP LPC3131. It has been 1454 verified that this new logic does not interfere with normal 1455 fixed-page ARM9 operation, but otherwise this new on-demand 1456 paging feature is untested. 1457 * Add support for the CodeSourcery toolchain to the Olimex-lpc2378 1458 port and for the Neuros OSD port. 1459 * The Neuros OSD port has been updated to work with the production 1460 v1.0 OSD (previously it only worked with the development board). 1461 * And some miscellaneous feature enhancements as detailed in the 1462 ChangeLog. 1463 1464This includes several important bugfixes: 1465 1466 * NXP LPC17xx - Fixed a critical bug in the GPIO configuration 1467 logic: When attempting to set no pull-up or pull-down (floating), 1468 it would, instead, select pull-down. 1469 1470 * TI/Luminary LM3Sxxxx - Fixed: 1471 (1) A logic error in an address table lookup. 1472 (2) GPIO port encoding the limited support to only 8 GPIO ports. 1473 1474 * Corrected the lease time in the DHCPC implementation: It was 1475 not in host byte order. 1476 1477 * And several other less important bugs as documented in the 1478 ChangeLog: Warnings, cornercase compilation problems, etc. 1479 1480NuttX-5.10 1481---------- 1482 1483This is the 57th release of NuttX. This release includes a combination 1484of some new features as well as several bugfixes. New features 1485include: 1486 1487 * TI/Luminary Stellaris LM3S9B96: 1488 Header file changes contributed by Tiago Maluta. 1489 * TI/Luminary Stellaris LM3S8962: 1490 Header file changes and support for the Stellaris LM3S8962 1491 Ethernet+CAN Evaluation Board contributed by Larry Arnold. 1492 * On-Demand Paging Support: 1493 The basic logic for the On-Demand Paging feature is complete, 1494 implemented for the NXP LPC3131, and partially tested. See 1495 http://www.nuttx.org/NuttXDemandPaging.html. Some additional 1496 test infrastructure will be needed in order to complete the 1497 verification. See configs/ea3131/README.txt for details. 1498 * Two Pass Build Support: 1499 The make system now supports a two pass build where a relocatable, 1500 partially linked object is created on the first pass and that 1501 object is linked with the NuttX libraries to produce the final 1502 executable on the second pass. This two pass build is currently 1503 only used to support the On-Demand paging feature: The first 1504 pass link forces critical logic into the locked text region; 1505 the second pass builds the NuttX executable more-or-less as 1506 normal. 1507 * CONFIG_APP_DIR: 1508 Generalized the way in which applications are built and linked 1509 with NuttX. The new configuration CONFIG_APP_DIR replaces 1510 CONFIG_EXAMPLE. CONFIG_EXAMPLE used to identify the sub-directory 1511 within the NuttX examples/ directory that held the example 1512 application to be built. That made it awkward to configure to 1513 build an application that resides outside of the NuttX examples/ 1514 directory. CONFIG_APP_DIR is more general; it can be used to 1515 refer to any directory containing the application to be built. 1516 1517 For people who have their own configurations and/or Makefiles, 1518 you will need to make a couple of changes: 1519 1520 - Replace all occurrences of CONFIG_EXAMPLE=foobar with 1521 CONFIG_APP_DIR=examples/foobar in all of the configuration 1522 files. 1523 - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with 1524 $(CONFIG_APP_DIR) 1525 - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) 1526 with libapp$(LIBEXT) in your Makefiles. 1527 - Check any other occurrences of CONFIG_EXAMPLE. 1528 1529 * Several bugfixes are included as well as code changes to eliminate 1530 some warnings. See the ChangeLog for details. 1531 1532NuttX-5.11 1533---------- 1534 1535This is the 58th release of NuttX. This is a bugfix release. 1536 1537 * One very important bug fixes a race condition that can occur 1538 using semaphores that can be awakened by signals. Under this 1539 particular race condition, a task could hang waiting for a 1540 semaphore. 1541 * Corrections to lm3s8962 port contributed by Larry Arnold. That 1542 port is purported to work correctly with these changes in place. 1543 1544Plus less critical bugfixes as detailed in the ChangeLog. New features 1545include: 1546 1547 * A new configuration to support the mbed.org LPC1768 board. 1548 (Contributed by Dave Marples.) 1549 * A driver for the Atmel AT45DB161D 4Mbit SPI FLASH part 1550 1551NuttX-5.12 1552---------- 1553 1554This is the 59th release of NuttX. This is a critical bugfix release. 1555 1556 * Fixed an important error in the signal trampoline logic. 1557 Essentially, interrupts are re-enabled while the signal handler 1558 executes, but the logic to re-disable the interrupts before 1559 returning from the signal handler trampoline was missing. Under 1560 certain circumstances, this can cause stack corruption. This 1561 was discovered by David Hewson on an ARM9 platform, but since 1562 the code has been leveraged, the bug has been propagated from 1563 ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 -- 1564 almost every architecture. The correction has been incorporated 1565 for all architectures but only verified on a few. 1566 1567Other notable changes in NuttX-5.12: 1568 1569 * A complete port for the AVR32 (AT32UC3B0256) is incorporated 1570 in the source tree. Testing of this port is underway now. This 1571 release was made before verifying this port in order to get the 1572 important bugfix in place. 1573 1574 * Other miscellaneous bugfix and enhancements as noted in the 1575 ChangeLog. 1576 1577NuttX-5.13 1578---------- 1579 1580This is the 60th release of NuttX. Headlines for this release 1581include: 1582 1583 * AVR32, www.mcuzone.com AVR32DEV1 1584 1585 The port for the www.mcuzone.com AVRDEV1 board based on the 1586 Atmel AT32UC3B0256 MCU was (almost) fully integrated. The port 1587 now successfully passes the NuttX OS test (examples/ostest). 1588 A NuttShell (NSH) configuration is in place (see the NSH User 1589 Guide at http://www.nuttx.org/NuttShell.html). Testing of that 1590 NSH configuration, however, has been postponed (because it got 1591 bumped by the Olimex LPC1766-STK port -- see below) 1592 1593 Current Status: I think I have a hardware problem with my serial 1594 port setup. There is a good chance that the NSH port is complete 1595 and functional, but I am not yet able to demonstrate that. At 1596 present, I get nothing coming in the serial RXD line (probably 1597 because the pins are configured wrong or I have the MAX232 1598 connected wrong). 1599 1600 A complete port will include drivers for additional AVR32 UC3 1601 devices -- like SPI and USB --- and will be available in a 1602 later release, time permitting. 1603 1604 * LPC1766, Olimex LPC1766-STK 1605 1606 Support for the Olimex-LPC1766 is newly added to NuttX and is 1607 still undergoing development, test, and integration. Verified 1608 configurations for the NuttX OS test and for the NuttShell (NSH, 1609 see the NSH User Guide at http://www.nuttx.org/NuttShell.html. 1610 Additional USB configurations are in the release as well, but 1611 they have not yet been verified. Goals for NuttX-5.14 include: 1612 (1) An Ethernet driver, (2) Verified USB support, and (3) SD 1613 card support. 1614 1615 * Additional changes and bugfixes as detailed in the ChangeLog. 1616 1617NuttX-5.14 1618---------- 1619 1620The 61st release of NuttX, NuttX-5.14, was made on November 27, 16212010. This release includes multiple, important bugfixes as well 1622as a new driver for the NXP LPC1766. 1623 1624This release corresponds with SVN release number: r3137 1625 1626Important bugfixes include: 1627 1628 * Cortex-M3 Hard Fault. Fixed a hard fault problem that can occur 1629 if certain types of interrupts are pending at the time another 1630 interrupt returns. This problem has only been observed on the 1631 LPC1766 (returning from a SYSTICK interrupt with a pending 1632 Ethernet interrupt). However, it is assumed that all Cortex-M3 1633 ports could have this as a latent bug. 1634 1635 * TCP/IP Sequence Number Bug. Corrected errors some important 1636 logic in the way that sequence numbers are managed when send() 1637 sends out packets before a previous packet has been acknowledged. 1638 Some of that send() logic was incompatible with logic in the 1639 uIP layer. Errors seen include: (1) The final final packet in 1640 a sequence of packets might be too large! In the THTTPD example, 1641 this might leave some garbage at the bottom of the display. Or 1642 (2) send() might hang with outstanding, unacknowledged data 1643 (and with no re-transmission requests). This was due to 1644 differences in sequence number handling in send() and in 1645 uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all 1646 of the bytes were acknowledged; send.c knew that they were not. 1647 1648 * One-Shot POSIX Timer Bug. Fixed an error in set-up of a one-shot 1649 POSIX timer. It was using the repetitive timer value (which 1650 is zero in the one-shot case), always resulting in a 10Ms timer! 1651 Found and fixed by Wilton Tong. 1652 1653Additional support has been included for the Olimex-LPC1766. Support 1654for that board was added to NuttX 5.13. This release extends that 1655support with an Ethernet driver. Verified configurations are now 1656available for the NuttX OS test, for the NuttShell (NSH, see 1657http://www.nuttx.org/NuttShell.html), for the NuttX network test, 1658and for the THTTPD webserver. (Additional USB configurations are 1659in the release as well, but those have not yet been verified. Goals 1660for NuttX-5.15 (and beyond) include: (1) Verified USB support, (2) 1661SD card support, and (3) LCD support. 1662 1663NuttX-5.15 1664---------- 1665 1666The 62nd release of NuttX, NuttX-5.15, was made on December 12, 16672010. This release includes several bugfixes as well as feature 1668enhancements, primarily for the Olimex LPC1766-STK board. 1669 1670Important bugfixes included: 1671 1672 * Additional fixes needed with the TCP sequence number problem 1673 "fixed" in NuttX-5.14. 1674 * In the send() logic, now checks if the destination IP address 1675 is in the ARP table before sending the packet; an ARP request 1676 will go out instead. This improves behavior, for example, on 1677 the first on the first GET request from a browser 1678 * All USB class drivers need to call DEV_CONNECT() when they are 1679 ready to be enumerated. That is, (1) initially when bound to 1680 the USB driver, and (2) after a USB reset. 1681 * The SPI_SETBITS macro was calling the SPI setmode method. 1682 * And several other bug fixes of lower importance (see the 1683 ChangeLog for details). 1684 1685And feature enhancements: 1686 1687 * The LPC176x Ethernet driver was using all of AHB SRAM Bank0 for 1688 Ethernet packet buffers (16K). An option was added to limit 1689 the amount of SRAM used for packet buffering and to re-use any 1690 extra Bank0 memory for heap. 1691 1692 * Enabled networking and SD/MMC card support in the Olimex 1693 LPC1766-STK NuttShell (NSH) configuration. 1694 1695 * The LPC176x USB driver is now fully fully functional. 1696 * Added an optional cmddata() method to the SPI interface. Some 1697 devices require an additional out-of-band bit to specify if the 1698 next word sent to the device is a command or data. The cmddata 1699 method provides selection of command or data. 1700 1701 * A driver for the Nokia 6100 LCD (with either the Phillips PCF8833 1702 LCD controller and for the Epson S1D15G10 LCD controller) and 1703 an NX graphics configuration for the Olimex LPC1766-STK have 1704 been added. However, neither the LCD driver nor the NX 1705 configuration have been verified as of the this release. 1706 1707NuttX-5.16 1708---------- 1709 1710The 63rd release of NuttX, Version 5.16, was made on January 10, 17112010 and is available for download from the SourceForge website. 1712This release includes initial support for USB host in NuttX. The 1713USB host infrastructure is new to NuttX. This initial USB host release 1714is probably only beta quality; it is expected the some bugs remain 1715in the logic and that the functionality requires extension. 1716 1717Below is a summary of the NuttX USB host implementation as extracted 1718from the NuttX Porting Guide: 1719 1720 6.3.9 USB Host-Side Drivers 1721 * include/nuttx/usb/usbhost.h. All structures and APIs needed to 1722 work with USB host-side drivers are provided in this header 1723 file. 1724 * struct usbhost_driver_s. Each USB host controller driver must 1725 implement an instance of struct usbhost_driver_s. This structure 1726 is defined in include/nuttx/usb/usbhost.h. Examples: 1727 arch/arm/src/lpc17xx/lpc17_usbhost.c. 1728 * struct usbhost_class_s. Each USB host class driver must implement 1729 an instance of struct usbhost_class_s. This structure is also 1730 defined in include/nuttx/usb/usbhost.h. Examples: 1731 drivers/usbhost/usbhost_storage.c 1732 * USB Host Class Driver Registry. The NuttX USB host infrastructure 1733 includes a registry. During its initialization, each USB host 1734 class driver must call the interface, usbhost_registerclass() 1735 in order add its interface to the registry. Later, when a USB 1736 device is connected, the USB host controller will look up the 1737 USB host class driver that is needed to support the connected 1738 device in this registry. Examples: drivers/usbhost/usbhost_registry.c, 1739 drivers/usbhost/usbhost_registerclass.c, and 1740 drivers/usbhost/usbhost_findclass.c, 1741 * Detection and Enumeration of Connected Devices. Each USB host 1742 device controller supports two methods that are used to detect 1743 and enumeration newly connected devices (and also detect 1744 disconnected devices): 1745 + int (*wait)(FAR struct usbhost_driver_s *drvr, bool connected); 1746 Wait for a device to be connected or disconnected. 1747 + int (*enumerate)(FAR struct usbhost_driver_s *drvr); 1748 Enumerate the connected device. As part of this enumeration 1749 process, the driver will (1) get the device's configuration 1750 descriptor, (2) extract the class ID info from the configuration 1751 descriptor, (3) call usbhost_findclass() to find the class 1752 that supports this device, (4) call the create() method on 1753 the struct usbhost_registry_s interface to get a class instance, 1754 and finally (5) call the connect() method of the struct 1755 usbhost_class_s interface. After that, the class is in charge 1756 of the sequence of operations. 1757 * Binding USB Host-Side Drivers. USB host-side controller drivers 1758 are not normally directly accessed by user code, but are usually 1759 bound to another, higher level USB host class driver. The class 1760 driver exports the standard NuttX device interface so that the 1761 connected USB device can be accessed just as with other, similar, 1762 on-board devices. For example, the USB host mass storage class 1763 driver (drivers/usbhost/usbhost_storage.c) will register a 1764 standard, NuttX block driver interface (like /dev/sda) that can 1765 be used to mount a file system just as with any other other 1766 block driver instance. In general, the binding sequence is: 1767 1768 1. Each USB host class driver includes an initialization entry 1769 point that is called from the application at initialization 1770 time. This driver calls usbhost_registerclass() during this 1771 initialization in order to makes itself available in the 1772 event that the device that it supports is connected. Examples: 1773 The function usbhost_storageinit() in the file 1774 drivers/usbhost/usbhost_storage.c 1775 2. Each application must include a waiter thread thread that 1776 (1) calls the USB host controller driver's wait() to detect 1777 the connection of a device, and then (2) call the USB host 1778 controller driver's enumerate method to bind the registered 1779 USB host class driver to the USB host controller driver. 1780 Examples: The function nsh_waiter() in the file 1781 configs/nucleus2g/src/up_nsh.c and the function nsh_waiter() 1782 in the file configs/olimex-lpc1766stk/src/up_nsh.c. 1783 3. As part of its operation during the binding operation, the 1784 USB host class driver will register an instances of a standard 1785 NuttX driver under the /dev directory. To repeat the above 1786 example, the USB host mass storage class driver 1787 (drivers/usbhost/usbhost_storage.c) will register a standard, 1788 NuttX block driver interface (like /dev/sda) that can be 1789 used to mount a file system just as with any other other 1790 block driver instance. Examples: See the call to 1791 register_blockdriver() in the function usbhost_initvolume() 1792 in the file drivers/usbhost/usbhost_storage.c. 1793 1794NuttX-5.17 1795---------- 1796 1797The 64th release of NuttX, Version 5.17, was made on January 19, 17982011 and is available for download from the SourceForge website. 1799This release follows close on the heels of the 5.16 release and 1800extends the USB host capabilities first introduced in that version. 1801 1802 * The LPC17xx USB host controller driver was extended to (1) add 1803 support for low-speed devices, (2) handle multiple concurrent 1804 transfers on different endpoints (still only one TD per endpoint), 1805 and (3) handle periodic interrupt endpoint types. 1806 1807 * Add a USB host HID keyboard class driver. Now you can connect 1808 a standard USB keyboard to NuttX and receive keyboard input for 1809 an application. 1810 1811And other changes as detailed in the ChangeLog. 1812 1813NuttX-5.18 1814---------- 1815 1816The 65th release of NuttX, Version 5.18, was made on February 27, 18172011 and is available for download from the SourceForge website. 1818This is first release from the new NuttX SVN repository. This 1819release is made primarily to keep the release tarball in synchronization 1820with SVN. Many smaller changes have been made as identified in the 1821ChangeLog. Headlines include: 1822 1823 * Incorporate several important uIP patches -- including the well 1824 known patch to handle missing SYNACK. 1825 * The Freescale mc8s12ne64 port is code complete but testing has 1826 not yet begun due to toolchain issues. Added support for the 1827 Future Electronics Group NE64 Badge board. 1828 * Added support for a new STM32 board, the ISOTEL NetClamps VSN 1829 V1.2 ready2go sensor network platform. This board is based on 1830 a STM32F103RET6 and includes some interesting power saving/clock 1831 control extensions. 1832 * USB host support expanded to handle vendor specific USB devices. 1833 * Incorporated the LUFA HID parser. 1834 * Various bugfix as detailed in the ChangeLog 1835 1836NuttX-5.19 1837---------- 1838 1839The 66th release of NuttX, Version 5.19, was made on March 12, 2011 1840and is available for download from the SourceForge website. This 1841release includes several new features in various states of integration 1842and maturity: 1843 1844 * 486SX QEMU port. This port supports the Intel 486SX architecture 1845 using the QEMU simulator. Initial functionality is in place a 1846 partially tested. There are still some outstanding issues with 1847 timer interrupts. 1848 * Platform specific application support. A new apps/ directory 1849 appears in this port. This apps/ directory provides a mechanism 1850 for applications using NuttX to have a highly customized 1851 initialization process. It supports a set of end-user applications 1852 than can be executed (1) standalone so you can have a fully 1853 customized application startup, or (2) on top of NSH. Think 1854 of it this way: In a buckled-up embedded application, your 1855 end-user programs will probably have their own dedicated start-up 1856 logic. But, during development, you might want to have you 1857 applications available and executable from the NSH command line. 1858 This apps/ add-on (and NSH hooks) was contributed by Uros to 1859 accomplish just that. 1860 * NSH was also extended to support application specific ROMFS 1861 /etc/init.d/rcS start-up scripts. This feature, as well, as 1862 all of the above-mentioned apps/ directory support was contributed 1863 by Uros Platise 1864 * Additional NSH improvements and bug fixes. See the Changelog 1865 for details. 1866 * This release also provides a new SLIP network driver. This 1867 driver should support point-to-point network communications to 1868 a host using TCP/IP or UDP. This driver is code complete, but 1869 not tested in this release. 1870 * New RAMTRON FRAM driver (contributed by Uros Platise) 1871 * New generic 16550 UART driver. 1872 * Cortex-M3 Power improvements: Waits for Interrupt (WFI) in idle 1873 loop for reduced power consumption (LPC17xx and STM32 only - 1874 contributed by Uros Platise)) 1875 * New waitpid() system interface. 1876 * Additional bugfixes: pipes, stdint.h, STM32 SDIO and SPI drivers 1877 1878NuttX-6.0 1879--------- 1880 1881The 67th release of NuttX, Version 6.0, was made on March 21, 2011 1882and is available for download from the SourceForge website. The 1883version number of this release was bumped from 5.19 to 6.0. A 1884change in the major revision number is used to reflect an incompatibility 1885with previous versions. In this release, the NuttX core OS 1886functionality has been separated from NuttX application-related 1887functionality. These are provided as separate tarballs: 1888 1889 * nuttx-6.0.tar.gz, and 1890 * apps-6.0.tar.gz 1891 1892The purpose of this separation is both to better organize and 1893modularize the NuttX source tree, but also to provide better support 1894for incorporation of end-user applications with Nuttx. 1895 1896The incompatibility results from the changes to the board configuration 1897logic needed to supported the separable application. The major 1898changes to the configuration include: 1899 1900 * CONFIG_APPS_DIR - This should not be set. The default is 1901 ../apps. This should only be set if you have a custom, 1902 product-specific application directory in some different location. 1903 1904 * appconfig - Each board configuration now requires a new file 1905 called 'appconfig.' As its name suggests, this file provides 1906 new configuration information needed by the logic in ../apps. 1907 1908In addition to this major reorganization in the directory structure, 1909this release also includes some important extensions to existing 1910features and some important bugfixes. These include: 1911 1912 * The SLIP driver was been well debugged and significantly 1913 re-designed. Now you can have an Ethernet connection to you 1914 board even if you have no Ethernet hardware. How cool is that? 1915 1916 * The QEMU i486 port is now functional. It has also been reported 1917 to work on the Bifferboard (see http://bifferos.bizhat.com/). 1918 1919 * And extensions to the uIP driver interface, and 1920 1921 * Bug fixes to fopen() and STM32 GPIO configuration 1922 1923Please see the ChangeLog for details. 1924 1925NuttX-6.1 1926--------- 1927 1928The 68th release of NuttX, Version 6.1, was made on April 10, 2011 1929and is available for download from the SourceForge website. The 19306.0 release introduced a detach-able application environment to 1931build applications outside of the NuttX source tree. The primary 1932purpose of this release is to correct numerous build problems 1933introduced by that architectural change: 1934 1935 * In many newer environments, NuttX produced strange Makefile 1936 errors but built correctly in older environments. A fix provided 1937 by Rafael Noronha was incorporated and is reported to fix those 1938 build problems. 1939 * The apps/ directory build system would not handle Windows-native 1940 toolchains due to obscure path formatting issues. 1941 * And other problems as detailed in the Changelog. 1942 1943Many additional changes were made in the 6.1 release for another 1944major architectural change: NuttX will now build as a separately 1945linked microkernel. In this build option the RTOS builds as a 1946kernel, applications build separately and interface with kernel via 1947system calls. Applications run in user mode and kernel logic users 1948in kernel-mode. This provides a secure environment for NuttX. This 1949feature is fully coded in NuttX-6.1, but has not been tested due 1950to higher priority tasks that have arisen. 1951 1952Related to this change, support for the Cortex-M3 memory protection 1953unit (MPU) has been integrated with the NuttX kernel build to provide 1954an even higher level of security. 1955 1956NOTE: This kernel build is an option; the default build configuration 1957is still the standard, flat, unsecured RTOS as in previous releases. 1958 1959Additional new features in this release: 1960 1961 * Support for LPC17xx GPIO interrupts (with much support from 1962 Decio Renno). 1963 * Basic timer support for STM32 (Contributed by Uros Platise) 1964 * A binfs file system. This is a tiny pseudo file system that 1965 lets named applications to be viewed and accessed in NSH under 1966 the /bin directory. 1967 * An I2C-based driver for the LIS331DL MEMS motion sensor. 1968 (Contributed by Uros Platise.) 1969 * A configuration for the Embedded Artists LPCXpresso LPC1768 board. 1970 * The user_initialize() interface has been removed. 1971 1972And several bugfix associated with SD drivers, opendir(), signed 19738-bit types (int8_t), and USB serial device. See the ChangeLog for 1974details. 1975 1976NuttX-6.2 1977--------- 1978 1979The 69th release of NuttX, Version 6.2, was made on May 6, 2011 and 1980is available for download from the SourceForge website. The 6.2 1981release includes several new features: 1982 1983 * NXFFS: The obvious new feature is NXFFS, the NuttX wear-leveling 1984 FLASH file system. This new file system is intended to be 1985 small for the MCU usage and has some limitations. No formal 1986 documentation of NXFFS yet exists. See the fs/nxffs/README.txt 1987 file for details (see 1988 http://svn.code.sf.net/p/nuttx/code/trunk/nuttx/fs/nxffs/README.txt?view=log) 1989 * Support for NXP LPCXpresso LPC1768 board on the Embedded 1990 Artists base board. The Code Red toolchain is supported under 1991 either Linux or Windows. Verified configurations include 1992 dhcpd, nsh, nx, ostest, thttpd, and usbstorage. 1993 * Support for the Univision UG-9664HSWAG01 OLED with Solomon 1994 Systech SD1305 LCD controller. 1995 * A new RAM MTD driver with FLASH simulation capability. 1996 * A version.h file is now automatically generated so that C code 1997 can now be version aware. 1998 1999In addition to these new feature, several important bugfixes are 2000included in this release correcting problems with dup2(), LPC17xx 2001GPIO interrupts, LPC17xx UART2/3, the FAT file system, build issues, 2002and strrch(). See the ChangeLog for more details. 2003 2004NuttX-6.3 2005--------- 2006 2007The 70th release of NuttX follows only a nines days after the release 2008of version 6.2. It was released on May 15, 2011. This special 2009back-to-back release was made so that the current released version 2010of NuttX will correspond to the initial release from the RGMP 2011project. 2012 2013This release adds architecture support and build configuration for 2014RGMP. RGMP is a project for running GPOS and RTOS simultaneously 2015on multi-processor platforms. See 2016http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further 2017information about RGMP. 2018 2019This release also includes support for STM32 FLASH, build improvements, 2020and initial, incomplete support for the MicroChip PIC32MX MCU. Bug 2021fixes are included for some build problems, USB host class driver 2022error handling, NX graphics color mapping, and problems with C 2023standard I/O buffer flushing. See the ChangeLog for further details. 2024 2025NuttX-6.4 2026--------- 2027 2028The 71st release of NuttX, Version 6.4, was made on June 5, 2011 2029and is available for download from the SourceForge website. The 20306.4 release includes several new features: 2031 2032 * A new, full-featured FTP client. This client may be used as a library 2033 for automated FTP or via an FTP client shell. The FTP shell 2034 supports the following commands: cd, chmod, get, help, idle, 2035 login, ls, quit, mkdir, noop, put, pwd, rename, rhelp, rm, 2036 rmdir, size, time, and up. A configuration is available for 2037 the NXP LPC17xx to demonstrate this functionality. 2038 * A functional C1101 wireless driver (contributed by Uros Platise) 2039 * A PCI-based E1000 Ethernet driver (contributed by Yu Qiang) 2040 * New C library functions: inet_addr() (contributed by Yu Qiang), 2041 strndup(), asprintf() 2042 * Reduced memory allocation overhead for MCUs with small heaps (<64K). 2043 * fdopen() now works with socket descriptors allowing standard 2044 buffered C functions to be used for network communications. 2045 * The NSH ifconfig command can now be used to set or change the 2046 IP address (contributed by Yu Qiang) 2047 2048This release also includes some completed but untested functionality. 2049 2050 * The MicroChip PIC32MX port is now code complete and ready to 2051 begin testing. Unfortunately, testing will be delayed due to 2052 tool issues. 2053 * Support for the NXP LPC315x MCUs. 2054 2055Additional miscellaneous enhancements and bug fixes to task_delete(), 2056recvfrom(), and other changes as noted in the ChangeLog. 2057 2058NuttX-6.5 2059--------- 2060 2061The 72nd release of NuttX, Version 6.5, was made on June 21, 2011 2062and is available for download from the SourceForge website. The 20636.5 release is all about support for the Atmel 8-bit AVR family. 2064I have been interested in the AVR family for some time but because 2065of the severe SRAM constraints and because of the availability of 2066many tiny schedulers for the AVR, it has not been "on the radar 2067screen." However, I have recently become interested because of 2068interest expressed by members of the forum and because of the 2069availability of newer, larger capacity AVR parts (that I don't have 2070yet). 2071 2072This release corresponds with SVN release number: r3730 2073 2074This release includes support for the following AVR boards. As 2075with any initial support for new architectures, there are some 2076incomplete areas and a few caveats that need to be stated. Here 2077they are, ordered from the least to the most complete: 2078 2079 * SoC Robotics Amber Web Server (ATMega128). 2080 2081 This port of NuttX to the Amber Web Server from SoC Robotics 2082 (http://www.soc-robotics.com/index.htm). Is only partially in 2083 place. The Amber Web Server is based on an Atmel ATMega128 2084 (128K FLASH but only 4K of SRAM). 2085 2086 STATUS: Work on this port has stalled due to toolchain issues. It 2087 is complete, but untested. 2088 2089 * Micropendous 3 AT9USB647 2090 2091 This port of NuttX to the Opendous Micropendous 3 board. The 2092 Micropendous3 may be populated with an AT90USB646, 647, 1286, 2093 or 1287. See http://code.google.com/p/opendous/. I have only 2094 the AT90USB647 version for testing. This version has very 2095 limited memory resources: 64K of FLASH and 4K of SRAM. 2096 2097 STATUS: The basic port was released in NuttX-6.5. This basic 2098 port consists only of a "Hello, World!!" example that demonstrates 2099 initialization of the OS, creation of a simple task, and serial 2100 console output. The tiny SRAM limits what you can do with the 2101 AT90USB647 (see issues below). 2102 2103 * PJRC Teensy++ 2.0 AT9USB1286 2104 2105 This is a port of NuttX to the PJRC Teensy++ 2.0 board. This 2106 board was developed by PJRC (http://pjrc.com/teensy/). The 2107 Teensy++ 2.0 is based on an Atmel AT90USB1286 MCU with 128K 2108 of FLASH and 8K of SRAM; a little more room to move than the 2109 AT90USB647. 2110 2111 STATUS: The basic port was released in NuttX-6.5. This basic 2112 port consists of a "Hello, World!!" example and also slightly 2113 simplified NuttShell (NSH) configuration (see the NSH User Guide 2114 at http://www.nuttx.org/NuttShell.html). 2115 2116 An SPI driver and a USB device driver exist for the AT90USB as 2117 well as a USB mass storage configuration. However, this 2118 configuration is not fully debugged as of the NuttX-6.5 release. 2119 2120AVR-specific issues. The basic AVR port is solid and biggest issue 2121for using AVR is its tiny SRAM memory and its Harvard architecture. 2122Because of the Harvard architecture, constant data that resides to 2123flash is inaccessible using "normal" memory reads and writes (only 2124SRAM data can be accessed "normally"). Special AVR instructions 2125are available for accessing data in FLASH, but these have not been 2126integrated into the normal, general purpose OS. 2127 2128Most NuttX test applications are console-oriented with lots of 2129strings used for printf and debug output. These strings are all 2130stored in SRAM now due to these data accessing issues and even the 2131smallest console-oriented applications can quickly fill a 4-8K 2132memory. So, in order for the AVR port to be useful, one of two 2133things would need to be done: 2134 21351. Don't use console applications that required lots of strings. 2136 The basic AVR port is solid and your typical deeply embedded 2137 application should work fine. 2138 21392. Create a special version of printf that knows how to access 2140 strings that reside in FLASH (or EEPROM). 2141 2142NuttX-6.6 2143--------- 2144 2145The 73rd release of NuttX, Version 6.6, was made on July 11, 2011 2146and is available for download from the SourceForge website. The 21476.6 release adds several smaller features but is mostly a bugfix 2148release. 2149 2150Bugfixes include 2151 2152 * Fixed several NX Graphics bugs: Rendering fonts at >8 bits-per-pixel, 2153 graphics move logic, and display artifacts that appear when a 2154 window is closed. 2155 * Corrections to the USB host mass storage class driver 2156 * STM32 bugfixes: serial driver, GPIO interrupt handling 2157 * LPC17xx: Changes for a success compilation with no console. 2158 * Corrections to the Teensy AT90USB SD driver 2159 * Changes for a clean compilation under the ZDS-II toolchain. 2160 2161Minor features: 2162 2163 * Add logic to extract printf strings from FLASH (but there are 2164 still printf issues for that target) 2165 * Added a configuration for the Sure Electronics PIC32MX board. 2166 However, higher priority tasks have stopped work on that 2167 configuration. 2168 * Added several new configurations for the STMicro STM3210E-EVAL 2169 board. 2170 * Added support for the STM3210E-EVAL board: (1) LCD in either 2171 landscape or portrait mode, and (2) interrupting buttons. 2172 * Added a configuration option to use different serial ports for 2173 debug and for the NSH serial console (there are some issues 2174 with CR-LF expansion and character echo if NSH is not run on 2175 the console). 2176 * Standardized the button press and button interrupt interfaces 2177 so that they are common across all boards. 2178 * Added a new graphics example that focuses on placing text on 2179 the background while pop-up windows occur. Text should continue 2180 to update normally with or without the popup windows present. 2181 * Added ARM stack checking logic. 2182 2183See the ChangeLog for a detailed description of these changes. 2184 2185NuttX-6.7 2186--------- 2187 2188The 74th release of NuttX, Version 6.7, was made on August 2, 2011 2189and is available for download from the SourceForge website. Note 2190that release consists of two tarballs: nuttx-6.7.tar.gz and 2191apps-6.7.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2192file for build information). Changes in this release are summarized 2193below: 2194 2195 * New OS APIs: Add the standard sem_timedwait() interface. 2196 * FAT File System: Adds (optional) support for VFAT long file 2197 names. 2198 * USB: Now the mass storage device can be connected when needed 2199 and disconnected when not needed (or re-connected as a different 2200 kind of device). 2201 * Touchscreen Support: Defined a new NuttX touchscreen interface. 2202 Added a driver for the TI TSC2007 touchscreen controller chip. 2203 * NX Fonts: Add support for multiple fonts; developed a tool to 2204 convert open source fonts into NuttX format; Converted and 2205 installed nine new, high quality fontsets. 2206 * NX Graphics: Add new NX APIs to support drawing of wide lines 2207 in any orientation. Added new low level routines to set 2208 individual pixel more efficiently. 2209 * Build system: Added a export target that will bundle up all 2210 of the NuttX libraries, header files, and the startup object 2211 into an exportable tarball. 2212 * LPC17xx: A CAN driver was contributed by Li Zhuoyi (Lzyy). 2213 * STM32: New NX-related configurations to exercise text and 2214 graphic image displays. 2215 * C Library: Added a fixed precision atan2() math function. 2216 * Bugfixes: Serial RX overrun error, FAT upper/lower NT 8.3 name 2217 handling fixed. FAT directory allocation and initialization 2218 bug. STM32 SDIO DMA race condition bug. eZ80 UART1 serial 2219 driver errors (Paul Osmialowski) 2220 2221NuttX-6.8 2222--------- 2223 2224The 75th release of NuttX, Version 6.8, was made on August 19, 2011 2225and is available for download from the SourceForge website.

Note 2559that release consists of two tarballs: nuttx-6.15.tar.gz and 2560apps-6.15.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2561file for build information). 2562 2563This release corresponds with SVN release number: r4387 2564 2565New features and extended functionality: 2566 2567 * General Drivers: Add support for (29-bit) extended CAN IDs. Add an 2568 infrastructure to support battery drivers. Add a driver for MAX17040x 2569 battery "fuel gauge". Add support for Composite USB drivers (in 2570 particular for a CDC/ACM with MSC USB composite driver). 2571 2572 Added a new RAM logging driver. This will allow debug output into 2573 a RAM buffer associated with a character driver at /dev/ramlog. 2574 Added the new command 'dmesg' to NSH that can be used to dump the 2575 current contents of the log. This is useful for systems that do not 2576 have the usual serial console (for example, if you only have a 2577 Telnet console with NSH). 2578 2579 * Networking: Add a lower level, primitive socket interface. Telnet 2580 driver: 2581 2582 A New Telnet daemon was created. It wraps a Telnet session within a 2583 character driver that can serve as a "controlling terminal." The 2584 Telnet session will then be inherited by tasks created from the 2585 Telnet session and the stdin/stdout from the created task will 2586 still go through the same Telnet connection. 2587 2588 * STM32 Drivers. PWM driver pulse count was limited to 128; now is 2589 (essentially) unlimited. Add support for (29-bit) extended CAN IDs. 2590 Add support for I2C3. The SDIO driver is (mostly) verified on the 2591 STM32 F4 platforms. 2592 2593 * LPC17xx Drivers. Extended the CAN driver so that the TSEG1 and TSEG2 2594 bit times can be set via the NuttX configuration. Add support for 2595 (29-bit) extended CAN IDs. 2596 2597 * PIC32 Drivers. The PIC32 Ethernet driver is code complete (but still 2598 untested). 2599 2600 * FTPD. Add a new FTP server daemon. This is based loosely on 2601 the hwport_ftpd library provided by Jaehyuk Cho. 2602 2603 * Library: Add support for on_exit(). Implemented tcsetattr() and 2604 tcgetattr(). Moved the old, too-smart fgets() to a new application 2605 library function called readline(). Dumbed down the original fgets(). 2606 Add strcasestr(), avsprintf(), inet_ntop(), and inet_pton(). 2607 Add support to enable or disable debug output. 2608 2609 * Build system: Support for building a 32-bit simulation executable on 2610 a 64-bit Linux machine. Correct a dependency issue in the arch/*/src/board 2611 directory. 2612 2613Bugfixes: 2614 2615 * System: Correct PTHREAD_MUTEX_INITIALIZER 2616 2617 * FAT: Fix an error in the FAT statfs() reported by David Sidrane. 2618 2619 * STM32: Fix clock frequencies for APB2 timers. Correct AFIO register 2620 offset. 2621 2622 * PIC32. Correct GPIOs used for LEDs on the Sure PIC32MX board. 2623 2624 * NSH. Wait for a USB connection if a USB serial class is used to 2625 interface with the host. 2626 2627Additional bugfixes, name changes, and other differences as detailed in the 2628ChangeLog. 2629 2630NuttX-6.16 2631---------- 2632 2633The 83rd release of NuttX, Version 6.16, was made on March 10, 2012, 2634and is available for download from the SourceForge website. Note 2635that release consists of two tarballs: nuttx-6.16.tar.gz and 2636apps-6.16.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2637file for build information). 2638 2639This release corresponds with SVN release number: r4475 2640 2641New features and extended functionality: 2642 2643 * ARMv7M Support: Includes new, streamlined Cortex-M exception 2644 handling provided by Mike Smith. Context switching support for the 2645 Cortex-M4 FPU registers is now provided (in both "lazy" and "non-lazy" 2646 modes) 2647 2648 * General Drivers: Added a generic "upper half" Quadrature Encoder driver. 2649 The USB CDC/ACM serial driver can now be dynamically connected or 2650 disconnected from the host (programmatically or using NSH commands). 2651 2652 * STM32 Drivers: Added a "lower half" Quadrature Encoder driver. 2653 Verified the STM32 F4 DMA driver; Added F4 DMA support to the existing 2654 STM32 SDIO driver. 2655 2656 * STM32 Board Support. Added support for the STM32 F2 family and 2657 for the STM3220G-EVAL board (contributed by Gary Teravskis). 2658 Support is now included for C++ static constructors (verified using 2659 the Atollic toolchain). Added support for the SRAM available on the 2660 STM3240G-EVAL board. 2661 2662 * PIC32 Drivers. PIC32MX USB (device) driver is now functional. 2663 The PIC32MX Ethernet driver not yet fully verified (and an 2664 unverified SPI driver is also available). 2665 2666 * Networking. Added a lower-level, thread-independent socket layer. 2667 Parts of this layer were created in 6.15 to support the FTPD 2668 controlling terminal; this support has been extended in order 2669 to support an NFS file system (not yet released). 2670 2671 * NuttShell (NSH). NSH will now support a USB serial connection for 2672 the console (such as CDC/ACM). This is useful in environments 2673 where there is no physical serial port on the board. 2674 2675 * Build System. Reorgnaization of networking header files. 2676 2677Critical Bugfixes. The following bug fixes are considered critical: 2678 2679 * Networking: Fixed a "leak" in the TCP/IP read-ahead buffering logic. 2680 Corrected an error in TCP/IP sequence numbering/ACK logic which 2681 occurred when read-ahead buffering memory is exhausted. 2682 2683 * STM32 Drivers: Fixed an buffer sizing error in the STM32 Ethernet 2684 driver. 2685 2686Additional Bugfixes: Other important bug fixes are listed below. See 2687the ChangeLog of a complete, detailed list of bug fixes. 2688 2689 * Networking: Corrected recv()/recvfrom() return value.

Note 2703that release consists of two tarballs: nuttx-6.17.tar.gz and 2704apps-6.17.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2705file for build information). 2706 2707This release corresponds with SVN release number: r4607 2708 2709New features and extended functionality: 2710 2711 * Networking: Additional low-level, thread-independent socket 2712 interfaces (for NFS client support). 2713 2714 * RTC: Added a new interface call clock_synchronize(). This function 2715 will reload the system time from an RTC and is required when the 2716 system re-awakens from certain deep-sleep modes. 2717 2718 * Graphics: Add NxConsole. This is a character device driver that 2719 wraps an NX window and can be re-directed for stdout. This allows, 2720 for example, a pop-up graphics window that contains a NuttShell (NSH) 2721 session. A test of NxConsole is available at apps/examples/nxconsole. 2722 2723 * Watchdog Drivers: Added an interface definition an "upper half" 2724 driver to support watchdog timers. 2725 2726 * Calypso: Support for TI Calypso-based cellphones (as supported by 2727 the Osmocom-BB project) was contributed by members of the Osmocom-BB 2728 team. This includes configurations for the Compal e88 and e99 phones. 2729 2730 * USB Device Interface: Needed to extend the USB device interface 2731 because there was no mechanism for passing endpoint OUT data that 2732 may need to accompany a setup request. 2733 2734 * STM32 drivers: Added some power management controls for entering 2735 reduced power consumption states. An OTG FS driver was completed 2736 and partially verified (this driver seems to be functional but since 2737 it has been test so lightly, it might better be listed in the 2738 next section "Work in progress"). 2739 2740 * PIC32 drivers: The PIC32 Ethernet driver is now stable. The PIC32 2741 USB device controller driver is now functional (but not yet stable). 2742 2743 * PIC32 boards: Added support for the Sure DB-DP11212 PIC32 General 2744 Purpose Demo Board. There is now a PIC32 Starter Kit that 2745 provides NSH only through a Telnet connection. 2746 2747 * Build System: Some header files were moved into include/nuttx. 2748 The goal is to move any non-standard header files to include/nuttx 2749 or include/arch. Moved include/math.h to include/nuttx/math.h; 2750 this file is now only instantiated as the 'system' math.h if 2751 CONFIG_ARCH_MATH_H=y is defined. 2752 2753 * Tools: Added tools/cmpconfig.c, a tool for comparing two 2754 configuration files. 2755 2756Work in progress. This release includes some partially completed 2757work that is still not ready for prime time. 2758 2759 * NFS Client: Work is progressing on support for an NFS client 2760 file system. This is a port of the BSD NFS client file system 2761 that is being done by Jose Pablo Rojas V. 2762 2763 * Automated Configuration: Automated configuration based on the 2764 kconfig-frontends tool is being incorporated into the build 2765 system. The configuration is still not complete enough for 2766 general use in this release. 2767 2768 * STM32 Drivers: Added files that will (eventually) hold an STM32 2769 OTG FS host driver. This is still a work in progress. 2770 2771Bugfixes: 2772 2773 * Networking: Corrected a deadlock that only occurred when 2774 executing the NSH 'ifconfig' command over Telnet. 2775 2776 * File system: Fix incorrect return errno value from read() when 2777 the file is opened write-only. 2778 2779 * Graphics: Fix several compilation errors that have crept into the 2780 multi-user NX server because of lack of use. 2781 2782 * STM32: In order to use CAN2, both CAN1 and CAN2 clocking must be 2783 enabled. Fixed a troublesome bug in the STM32 F4 I2C driver that 2784 resulting in timeouts. 2785 2786 * LPC17xx: Fixes for errors the crept in the LPC17xx DAC logic 2787 Contributed by Lzyy). 2788 2789 * Build System: Reordered the link command line to account for new 2790 versions of libgcc.a that require symbols from the application 2791 (abort()). 2792 2793NuttX-6.18 2794---------- 2795 2796The 85th release of NuttX, Version 6.18, was made on May 19, 2012, 2797and is available for download from the SourceForge website. Note 2798that release consists of two tarballs: nuttx-6.18.tar.gz and 2799apps-6.18.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2800file for build information). 2801 2802The majority of changes in this release are focused on supporting the 2803synchronized release of NxWM, the NuttX tiny window manager. That 2804window manager is released as part of the NxWidgets package, but depends 2805upon many of the changes in this NuttX release. 2806 2807This release corresponds with SVN release number: r4751 2808 2809New features and extended functionality: 2810 2811 * Drivers. Added a watchdog timer driver infrastructure. Add general 2812 support for STMicro STMPE811 I/O Expander/touchscreen device. 2813 2814 * STM32. Add support for the STM32 IWDG and WWDG watchodog timers. DMA 2815 now supports cicular buffer mode; serial driver now uses circular 2816 DMA to improve Rx performance (Contributed by Mike Smith). 2817 2818 * STM3240G-EVAL Board. Add support for the LCD and for the STMPE811 2819 I/O Expander as a touchscreen controller. 2820 2821 * PIC32 Boards. Board support for the Mikroelektronika PIC32MX7 2822 Multimedia Board (MMB) and for the Sparkfun UBW32 PIC32 board. 2823 2824 * NX. Framed windows are now draw in three colors instead of just two. 2825 Numerous other extensions needed to support NxWM (see the ChangeLog 2826 for details). 2827 2828 * Library. Add prctl() command that can be used to setting and getting 2829 the names of threads. This (plus several other improvements and bug 2830 fixes) are part of a larger effort to improve task monitoring 2831 capabilities. 2832 2833Work in progress. This release includes some partially completed 2834work that is still not ready for prime time. 2835 2836 * NFS Client. Work is progressing on support for an NFS client 2837 file system. This is a port of the BSD NFS client file system 2838 that is being done by Jose Pablo Rojas V. 2839 2840 * Automated Configuration. Automated configuration based on the 2841 kconfig-frontends tool is being incorporated into the build 2842 system. The configuration is still not complete enough for 2843 general use in this release. 2844 2845 * STM32 Drivers. Added files that will (eventually) hold an STM32 2846 OTG FS host driver. This is still a work in progress. 2847 2848Bugfixes (see the change log for details) : 2849 2850 * sched_setscheduler() return value (Contributed by Richard Cochran). 2851 2852 * stdio. Ignore CONFIG_STDIO_LINEBUFFER if the file was opened in binary mode. 2853 2854 * fopen(). Correct an error in parsing open mode string. 2855 2856 * serial driver.

Fix an infinite loop that occurs when the serial 2862 device is unregistered. 2863 2864 * STM32 OTG FS device driver. Numerous fixes and the driver is partially 2865 functional but there are still some issues that become apparent when 2866 debug output is disabled. 2867 2868 * fcntl(). Always returned zero on success; however, some fcntl commands 2869 need to return non-zero values on success. 2870 2871 * graphics: Many multi-use mode fixes added to support NxWM (see the 2872 ChangeLog for details). Auto-raise is temporarily disabled in multi- 2873 user mode because it causes some problems with NxWM. 2874 2875 * on_exit(): Fix compilation errors if CONFIG_SCHED_ONEXIT is enabled. 2876 2877NuttX-6.19 2878---------- 2879 2880The 86th release of NuttX, Version 6.19, was made on June 15, 2012, 2881and is available for download from the SourceForge website. Note 2882that release consists of two tarballs: nuttx-6.19.tar.gz and 2883apps-6.19.tar.gz. Both may be needed (see the top-level nuttx/README.txt 2884file for build information). 2885 2886This release corresponds with SVN release number: r4847 2887 2888This release features new support for a Network File System (NFS) client. 2889This feature allows a tiny, embedded MCU to mount a remote file system 2890exported by an NFS server and then to access the file system as it would 2891any local file system. Then the tiny MCU can effectively have terabytes 2892of storage! 2893 2894This might be useful for data collection, for MCU configuration information, 2895for software updates, for providing modular, loadable code modes, controlling 2896a "farm" of MCUs, ... there are many possibilities and opportunities for 2897innovation! 2898 2899The NuttShell (NSH) now supports the following command: 2900 2901 nfsmount <server-address> <mount-point> <remote-path> 2902 2903That command will mount the remote NFS server directory <remote-path> at 2904<mount-point> on the target machine. <server-address> is the IP address of 2905the remote server. 2906 2907The NFS development was the graduation project of Jose Pablo Rojas V. who 2908is a student at the Instituto Tecnol�gico de Costa Rica (ITCR, or TEC). 2909A lot of effort went into understanding what a tiny, embedded NFS client should 2910do and getting the target resource usage to a bare minimum. Only around a 2911kilobyte or so of memory is required to run the NFS client (and most of that 2912for I/O buffers). Jose Pablo has spent several months living with NFS and 2913should be congratulated. 2914 2915Additional new features and extended functionality: 2916 2917 * Drivers: SSD1289 LCD driver, MIO283QT2 LCD driver 2918 2919 * LM3S: Additional register definition header files (contributed by Max 2920 Neklyudov). 2921 2922 * STM32 Boards: The STM32F4Discovery will now support an SSD1289 LCD, 2923 The STM3220G-EVAL board support is now equivalent to the STM3240G-EVAL 2924 board support. 2925 2926 * PIC32 Boards: The Mikroelektronika PIC32MX7 MMB board port is now 2927 functional, very complete, and stable. 2928 2929 * Graphics: The NxConsole will now take keyboard input from the NX graphics 2930 subsystem. This means that if there are multiple NxConsole windows, only 2931 the top instance that has focus will receive the keyboard input. 2932 2933 * apps/: Add the capability to use an arbitrary USB device as the console 2934 (not necessarily /dev/console). Additional enhancements for USB consoles. 2935 Added the 'mv' command. 2936 2937Work in progress. This release includes some partially completed 2938work that is still not ready for prime time. 2939 2940 * Automated Configuration. Automated configuration based on the 2941 kconfig-frontends tool is being incorporated into the build 2942 system. The configuration is still not complete enough for 2943 general use in this release. 2944 2945 * STM32 Drivers. Added files that will (eventually) hold an STM32 2946 OTG FS host driver. This is still a work in progress. 2947 2948Bugfixes (see the change log for details) : 2949 2950 * General: sleep() and usleep() return values, sig_timedwait() errno setting 2951 on timeout. 2952 * Drivers: STMPE811 touchscreen driver, USB PLC2303, USB CDC/ACM 2953 * STM32: Several USB device controller driver fixes, F4 interrupt priorities 2954 (contributed by Mike Smith). 2955 * Graphics: Keyboard input, fill trapezoid bug 2956 2957As well as other, less critical bugs (see the ChangeLog for details) 2958 2959NuttX-6.20 2960---------- 2961 2962The 87th release of NuttX, Version 6.20, was made on July 12, 2012, 2963and is available for download from the SourceForge website.

Revision r5447 should equivalent to release 6.24 of NuttX 6.24: 3282 3283 svn checkout -r5447 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3284 3285Or (HTTP): 3286 3287 svn checkout -r5447 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3288 3289Additional new features and extended functionality: 3290 3291 * RTOS: 3292 3293 - Implemented the POSIX pause() function (still has some compiance 3294 issues). 3295 - Tasking logic is extended to support the notion of address 3296 environments. An address environment is the key notion underlying 3297 "process" vs. tasks. If tasks are created with address environments 3298 (by binfmt), the OS will propogate that environment to child threads 3299 and will destroy the address environment when the "process" exists. 3300 - If support for the PATH variable is enabled, the OS start up logic 3301 will create an initial environment containing the default PATH 3302 setting (CONFIG_PATH_INITIAL). This initial PATH will then be 3303 inherited by all tasks. 3304 3305 * Binfmt 3306 3307 - The NuttX binary loaders have been updated to support the PATH 3308 environment variable. Now, if the PATH is properly defined, programs 3309 can be executed from mass storage using only the file name. This 3310 feature is added to support more standard behavior (eventually, NSH 3311 will support execution of programs in file systems by just entering 3312 the file name, perhaps in 6.25?). 3313 - The NXFLAT and ELF binary loaders have been extended to create 3314 address environments for any new tasks executed from the file system. 3315 This feature requires that the architecture support a memory management 3316 unit (MMU) and the address environment interfaces declared in 3317 include/nuttx/arch.h (currently, this is only supported by the z180). 3318 3319 * Drivers: LCD driver for the Univision UG-2864AMBAG01 OLED 3320 3321 * STM32: Support for STM32F100 high density chips contributed by Freddie 3322 Chopin. 3323 3324 * STM32 Drivers: Added optional RS-485 direction bit control (from 3325 Freddie Chopin). 3326 3327 * STM32 Boards: 3328 3329 - Support for generic STM32F100RC board contributed by Freddie Chopin. 3330 - stm32f4discovery/nxlines: STM32F4Discovery support for the 3331 UG-2864AMBAG01 OLED. 3332 - stm32f4discovery/winbuild: A version of the NuttX OS test 3333 configured to build natively on Windows. 3334 - stm32f4discovery/elf: Now uses the PATH variable to find ELF 3335 executables. 3336 - configs/cloudctrl: Added for Darcy Gong's CloudController board 3337 3338 * PIC32 Boards: Update the Mirtool configuration for Release 2 of the 3339 Mirtoo module. 3340 3341 * Calypso: Add Calypso keypad driver. From Denis Cariki. 3342 3343 * ZiLOG: 3344 3345 - Add support for the z180 chip family and, specifically, for 3346 the P112 retro hardware (see http://p112.feedle.net/). 3347 - All ZiLOG configurations updated to use the current ZDS-II 3348 and/or SDCC toolchains. 3349 3350 * Graphics: 3351 3352 - Add a semaphore handshake so that operations on buffers from 3353 the NXMU client will be blocked until the NX server operates on the 3354 buffer data (from Petteri Aimonen). 3355 - nxtk_subwindowmove() and nxtk_getwindow(): Improvements to clipping 3356 logic from Petteri Aimonen. 3357 3358 * C Library: lib/ sub-directory renamed libc/ (there is a new lib/ sub- 3359 directory that is used to hold all archives). 3360 3361 * C++: Exception stubs from Petteri Aimonen. 3362 3363 * Applications: 3364 3365 - Add NSH hexdump command to dump the contents of a file (or character 3366 device) to the console (contributed by Petteri Aimonen). 3367 - Extend the NSH ifconfig command plus various DHCPC improvements 3368 (from Darcy Gong). 3369 3370 * apps/examples: 3371 3372 - ostest: Replace large tables with algorithmic prime number 3373 generation. This allows the roundrobin test to run on platforms 3374 with minimal SRAM (Freddie Chopin). 3375 - keypadtest: A new keypad test example contributed by Denis Carikli. 3376 - elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these examples 3377 will now use a relative path to the program and expect the binfmt/ 3378 logic to find the absolute path to the program using the PATH 3379 variable. 3380 3381 * Build system: 3382 3383 - New top-level Makefiles: Makefile.unix and Makefile.win (along with 3384 numerous changes to other make-related files). This adds basic 3385 support for building NuttX natively under Windows from a CMD.exe 3386 window (rather than in a POSIX-like environment). This build: (1) 3387 Uses all Windows style paths, (2) Uses primarily Windows batch 3388 commands from cmd.exe, with (3) a few extensions from GNUWin32. 3389 3390 This capability should still be considered a work in progress 3391 because: (1) it has not been verfied on all targets and tools, 3392 and (2) still lacks some of the creature-comforts of the more 3393 mature environments (like a function configure.sh script and 3394 'make menuconfig' support). 3395 3396 - Example Windows native builds for STM32F4Discovery, eZ80, z16f, z8, 3397 Z80, and Z180. 3398 - Several configurations have been converted to work the kconfig- 3399 frontends mconf configuration tool: stm32f4discovery/nxlines, and 3400 all eZ80, z16f, z8, Z80, and Z180 configurations. 3401 - Architectures now include a common Toolchain.defs file that can be 3402 used to manage toolchains in a more configurable way (most of this 3403 contributed by Mike Smith). 3404 3405 * Build tools: 3406 3407 - Renamed tools/winlink.sh to tools/copydir.sh. 3408 - Several new tools/scripts to support the Windows native build: 3409 tools/mkdeps.bat, tools/mkdeps.c, tools/link.bat, unlink.bat, and 3410 copydir.bat. 3411 - tools/incdir.sh and incdir.bat now support an -s option to generate 3412 system header file paths. 3413 - tools/b16.c: Fixed precision math conversion utility. 3414 3415Bugfixes (see the change log for details). Some of these are very important 3416(marked *critical*): 3417 3418 * RTOS: Fix some backward conditional compilation in the work queue 3419 logic (Freddie Chopin). 3420 3421 * File System: Uninitialized variable caused assertions (from Lorenz 3422 Meier). 3423 3424 * Drivers: Partial fix for STM32 OTGFS device drivers and fix for short, 3425 unaligned writes in the flash translation layer (drivers/mtd/ftl.c), 3426 both from Petteri Aimonen. 3427 3428 * STM32 Drivers: 3429 3430 - Qencoder driver and TIM3 driver fixes from Ryan Sundberg. 3431 - Fix timeout delay calculation in the STM32 OTG FS host driver. 3432 3433 * LPC17xx Drivers: Resources not being properly released when I2C 3434 driver is un-initialized. 3435 3436 * Graphics: 3437 3438 - Fix logic when the mouse drags outside of the window; fix 3439 another "blocked message" handling case (both from Petteri Aimonen). 3440 - nxtk_filltrapwindow(): Correct an offset problem (also from Peterri 3441 Aimonen). 3442 - nxglib_splitline(): Correct the "fat flat line" bug. 3443 3444 * C Library: 3445 3446 - nrand() changes to prevent coefficients from becoming zero which 3447 would "lock up" the random number generate. 3448 - Add rounding functions to the math library (contributed by Petteri 3449 Aimonen). 3450 3451 * Build system: Changes to MIN definitions in all limit.h header files 3452 to avoid integer overflows. For example from (-128) to (-127 - 1) 3453 (from Petteri Aimonen). 3454 3455 * Applications: Modbus fixes from Freddie Chopin. 3456 3457As well as other, less critical bugs (see the ChangeLog for details) 3458 3459NuttX-6.25 3460---------- 3461 3462The 92nd release of NuttX, Version 6.25, was made on February 1, 2013, 3463and is available for download from the SourceForge website. Note 3464that release consists of two tarballs: nuttx-6.25.tar.gz and 3465apps-6.25.tar.gz. Both may be needed (see the top-level nuttx/README.txt 3466file for build information). 3467 3468This release corresponds with SVN release number: r5595 3469 3470Note that all SVN information has been stripped from the tarballs. If you 3471need the SVN configuration information, you should check out directly from 3472SVN. Revision r5595 should equivalent to release 6.25 of NuttX: 3473 3474 svn checkout -r5595 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3475 3476Or (HTTP): 3477 3478 svn checkout -r5595 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3479 3480Additional new features and extended functionality: 3481 3482 * OS Initialization 3483 3484 - Removed support for CONFIG_BUILTIN_APP_START. This is not really a 3485 useful feature and creates a violation of the OS layered 3486 architecture. 3487 3488 * Task Creation: 3489 3490 - Implement a simple vfork(). In NuttX-6.25, this interface is 3491 available only for ARM7/9, ARMv7-M (Cortext-M3/4), and MIPS32 3492 (PIC32MX) platforms. 3493 - exec() now sets the priority of the new task to the same priority as 3494 the parent task (instead of the arbirtrary value of 50). 3495 - New, partially complient implementations of execv() and execl(). 3496 These are only partially compliant because they do not overlay any 3497 existing "process space" but rather create the new task and exit(). 3498 - Add a complete implementation of posix_spawn(). This standard 3499 interface is a better match for an MMU-less architecture than are 3500 vfork() plus execv() or execl(). 3501 - Add a task start hook that will be called before the task main 3502 is started. This can be used, for example, to schedule C++ 3503 static constructors to run automatically in the context of the 3504 new task. 3505 3506 * Task Parentage 3507 3508 - Repartitioned tasking data structures. All shared resources are now 3509 collected together in a "task group". A task group includes the 3510 original task plus all of the pthreads created by the task. 3511 - Added support for remember the parent "task group" when a new task is 3512 started. 3513 - Added optional support to record the membership of each thread in 3514 the "task group". 3515 - Implement support for retaining child task status in the "task group" 3516 after the child task exists. This is behavior required by POSIX. 3517 But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and 3518 CONFIG_SCHED_CHILD_STATUS 3519 - Add internal logic to "reparent" a task. This is useful, 3520 for example, where the child task is created through a trampoline 3521 task that redirects I/O. Reparenting allows the caller of posix_spawn() 3522 to be reparented for the eventual child thread. 3523 - Added support for SIGCHLD. Sent to all members of the parent task 3524 group when the file member of the child task group exits. 3525 - If SIGCHLD and retention of child task exist status are enabled, then 3526 a more spec-compliant version of waitpid() is enabled. 3527 - New interfaces waitid() and wait() are also enabled when SIGCHLD 3528 is enabled. 3529 3530 * File System 3531 3532 - dup() and dup2() can new be used with opened files in a mounted file 3533 system. This supports re-direction of output in NSH to files. 3534 - The binfs file system was moved from apps/builtin to fs/binfs. The 3535 binfs file system was extended to support execution of "builtin 3536 applications" using exec(), execv(), execl(), or posix_spawn(). 3537 - Added logic based on SIGCHLD to automatically unload and clean-up 3538 after running a task that was loaded into memory. 3539 3540 * Binary Formats 3541 3542 - Much of the logic for "builtin applications" was moved from 3543 apps/builtin to nuttx/binfmt/libbuiltin. Includes some extensions 3544 contributed by Mike Smith. 3545 - A binary loader was added for builtin applications to support 3546 execution of "builtin applications" using exec(), execv(), 3547 execl(), or posix_spawn(). 3548 3549 * Drivers: 3550 3551 - Added logic to marshal and serialized "out-of-band" keyboard 3552 commands (such as cursor controls and key release events) intermixed 3553 with normal ASCII keypress data. The encoding is partially integrated 3554 in the HID keyboard driver and the decoding full integrated into the 3555 apps/examples hidkbd and keypadtest (the latter contributed by Denis 3556 Carlikli). 3557 - Driver for the UG-2864HSWEG01 OLED contributed by Darcy Gong. 3558 - Add support for removable serial devices (like USB serial). This 3559 support is enabled by CONFIG_SERIAL_REMOVABLE. 3560 3561 * ARMv7-M: 3562 3563 - Added an option to use the BASEPRI register to disable interrupts 3564 (instead of the PRIMASK). This eliminates some innocuous hardfaults 3565 that interfere with some debug tools. You need to switch to the 3566 BASEPRI method only if you have such tool interference. 3567 3568 * STM32 Drivers 3569 3570 - Bring STM32 F1 DMA capabilities up to par with the STM32 F2/F4 3571 (contributed by Mike Smith). 3572 - Add support for USART single wire mode (Contributed by the PX4 3573 team). 3574 - Updates to support for SPI DMA on the STM32 F1/F2/F4. From 3575 Petteri Aimonen. 3576 3577 * STM32 Boards: 3578 3579 - New configuration to support the UG-2864HSWEG01 OLED on the 3580 STM32F4Discovery board. 3581 - Added a posix_spawn() test configuration for the STM32F4Discovery. 3582 3583 * LM3S/LM4F 3584 3585 - Files and directories repartitioned to support both LM3S and LM4F 3586 using the STM32 organization as a model. 3587 - Partial definitions for the LM4F contributed by Jose Pablo Carballo 3588 (this is still a work in progress). 3589 3590 * LM3S Boards 3591 3592 - Added scripts and documentation to use OpenOCD with the LM3S (from 3593 Jose Pablo Carballo). 3594 3595 * LPC176x/LPC178x 3596 3597 - Files and directories repartitioned to support both LPC175x/LPC176x 3598 and the LPC177x/LPC178x families using the STM32 organization as a 3599 model. The LPC1788 port is a work in progress by Rommel Marcelo. 3600 3601 * LPC176x/LPC178x Boards: 3602 3603 - Added a configuration to support the Wave Share Open1788 board. 3604 This is still a work in progress by Rommel Marcelo. 3605 3606 * LPC2148 Boards: 3607 3608 - Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148 3609 and the UG_2864AMBAG01 OLED). 3610 - Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148 3611 and the UG_2864AMBAG01). 3612 3613 * Simulator: 3614 3615 - Add an nxlines configuration for the simulator. 3616 3617 * Networking: 3618 3619 - Add logic to work around delayed ACKs by splitting packets 3620 (contributed by Yan T.). 3621 - Split net_poll() to create the internal interface psock_poll(). 3622 3623 * LCDs: 3624 3625 - Added support for LCD1602 alphanumeric LCD (HD4468OU controller). 3626 3627 * Graphics: 3628 3629 - Added 5x8 monospace font. This tiny font is useful for graph 3630 labels and for small bitmapped display. Contributed by Petteri 3631 Aimonen. 3632 3633 * Build System: 3634 3635 - Add an options to better manage toolchain prefixes. 3636 - Redesigned how the context targer works in the apps/ directory. 3637 The old design caused lots of problems when changing configurations 3638 because there is no easy way to get the system to rebuild the 3639 context. This change should solve most the problems and eliminate 3640 questions like "Why don't I see my builtin application in NSH?" 3641 3642 * Kconfig Files: 3643 3644 - There are several new configurations that use the kconfig-frontends 3645 tools and several older configurations that have been converted to 3646 use these tools. There is still a long way to go before the conversion 3647 is complete: 3648 3649 configs/sim/nxwm 3650 configs/sim/nsh 3651 configs/stm3220g-eval/nxwm 3652 configs/stm32f4discovery/posix_spawn 3653 configs/olimex-lpc1766stk/nsh 3654 configs/olimex-lpc1766stk/hidkbd 3655 configs/olimex-lpc1766stk/nettest 3656 configs/open1788/ostest 3657 configs/stm32f4discovery/nsh 3658 configs/stm32f4discovery/usbnsh 3659 configs/lm326965-ek (all configurations) 3660 configs/mcu123-214x/nsh 3661 configs/ubw32/ostest 3662 3663 * Tools: 3664 3665 - tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell. 3666 - tools/configure.c: configure.c can be used to build a work-alike 3667 program as a replacement for configure.sh. This work-alike 3668 program would be used in environments that do not support Bash 3669 scripting (such as the Windows native environment). 3670 - tools/configure.bat: configure.bat is a small Windows batch 3671 file that can be used as a replacement for configure.sh in a 3672 Windows native environment. configure.bat is actually just a 3673 thin layer that executes configure.exe if it is available. If 3674 configure.exe is not available, then configure.bat will attempt 3675 to build it first. 3676 3677 * Applications: 3678 3679 - New and modified examples: 3680 3681 apps/examples/wlan: Remove non-functional example. 3682 apps/examples/ostest: Added a test of vfork(). Extend signal 3683 handler test to catch death-of-child signals (SIGCHLD). Add a 3684 test for waitpid(), waitid(), and wait(). 3685 apps/exampes/posix_spawn: Added a test of posix_spawn(). 3686 3687 - NSH: 3688 3689 NSH now supports re-direction of I/O to files (but still not from). 3690 The block driver source argument to the mount command is now 3691 optional for file systems that do not require a block driver. 3692 NSH can now execute a program from a file system using posix_spawn(). 3693 Added support for a login script. The init.d/rcS script will be 3694 executed once when NSH starts; the .nshrc script will be executed 3695 for each session: Once for serial, once for each USB connection, 3696 once for each Telnet session. 3697 3698 - Supports a new daemon that can be used to monitor USB trace outpout. 3699 - Removed non-functional wlan example. 3700 3701Bugfixes (see the ChangeLog for details). Some of these are very important: 3702 3703 * Tasking: 3704 3705 - Fixed a *critical* task exit bug. Here is the failure scenario: 3706 (1) sched_lock() is called increments the lockcount on the current 3707 TCB (i.e., the one at the head of the ready to run list), (2) 3708 sched_mergepending is called which may change the task at the head 3709 of the ready-to-run list, then (3) sched_unlock() is called which 3710 decrements the lockcount on the wrong TCB. The failure case that 3711 I saw was that pre-emption got disabled in the IDLE thread, locking 3712 up the whole system. 3713 3714 * Signals: 3715 3716 - sigtimedwait() would return a bad signal number if the signal was 3717 already pending when the function was called. 3718 3719 * Drivers: 3720 3721 - Some SD cards will appear busy until switched to SPI mode for 3722 first time. Having a pull-up resistor on MISO may avoid this 3723 problem, but this fix from Petteri Aimonen makes it work also 3724 without pull-up. 3725 3726 * STM32 Drivers: 3727 3728 - STM32 FLASH driver counting error (from Freddie Chopin). 3729 - STM32 F4 maximum SPI frequency was wrong (corrected by Petteri 3730 Aimonen). 3731 3732 * STM32 Boards 3733 3734 - Due to cloning of untested code, the logic to control on-board 3735 LEDs did not work on any STM32 boards. 3736 - Serial devices number /dev/ttyS0-5 is there is a serial console, 3737 but /dev/ttyS1-6 if there is no serial console. 3738 3739 * Binary Formats 3740 3741 - C++ static constructors execute now using a start taskhook 3742 so that they execute in the context of the child task (instead 3743 of in the context of the parent task). 3744 3745 * File Systems: 3746 3747 - Several FAT-related bugs fixed by Petteri Aimonen. 3748 3749 * Networking: 3750 3751 - Fix poll/select issure reported by Qiang: poll_interrupt() must call 3752 net_lostconnection() when a loss of connection is reported. Otherwise, 3753 the system will not remember that the connection has been lost and will 3754 hang waiting on a unconnected socket later. 3755 - Similar issues corrected for recvfrom() and send(). 3756 - Telnetd would hang in a loop if recv() ever returned a value <= 0. 3757 3758 * Libraries: 3759 3760 - fread() could hang on certain error conditions. 3761 - Can't handle SYSLOG output to a character device from the IDLE task 3762 (because the IDLE task can't block). 3763 3764 * Build System: 3765 3766 - Serial was driver was not being built if there is no console 3767 device. Obviously, the serial driver may be needed even in 3768 this case. 3769 3770 * Additional Bugfixes: 3771 3772 - sig_timedwait() and clock_time2ticks.c: Timing "rounding" logic 3773 - ARM9 Compilation issue with low vectors. 3774 - readline() return value 3775 - Others as detailed in the ChangeLog: HID keyboard, LPC17xx bit 3776 definitions, strndup(), PL2303, SYSLOG error handling, AT25, 3777 apps/examples. 3778 3779NuttX-6.26 3780---------- 3781 3782The 93rd release of NuttX, Version 6.26, was made on March 15, 2013, 3783and is available for download from the SourceForge website. Note 3784that release consists of two tarballs: nuttx-6.26.tar.gz and 3785apps-6.26.tar.gz. Both may be needed (see the top-level nuttx/README.txt 3786file for build information). 3787 3788This release corresponds with SVN release number: r5745 3789 3790Note that all SVN information has been stripped from the tarballs. If you 3791need the SVN configuration information, you should check out directly from 3792SVN. Revision r5745 should equivalent to release 6.26 of NuttX: 3793 3794 svn checkout -r5745 svn://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3795 3796Or (HTTP): 3797 3798 svn checkout -r5745 http://svn.code.sf.net/p/nuttx/code/trunk nuttx-code 3799 3800Additional new features and extended functionality: 3801 3802 * OS Initialization: 3803 3804 - Add an additional call-out to support board-specific driver 3805 initialization during the boot-up phase (available with 3806 CONFIG_BOARD_INITIALIZE=y). 3807 3808 * Tasking: 3809 3810 - New interface task_spawn() that is like posix_spawn(), but uses 3811 entry point addresses like task_create(). 3812 - Additional data restructuring as a continuation of the task group 3813 changes of NuttX 6.25. These data structures were moved from the 3814 TCB structure into the task group: pthread join data, 3815 atexit/on_exit callbacks, waitpid data structures, and message 3816 queues. 3817 - TCBs for tasks and pthreads are now separate structures. This 3818 saves a little memory since tasks do not have to carry the overhead 3819 for threads and vice versa. 3820 3821 * Kernel Build: 3822 3823 - Extensive changes were made to support the kernel build mode. In 3824 this mode, NuttX is built as a monolithic kernel. NuttX is built 3825 as a separate kernel mode "blob" and the applications are built 3826 as a separate user mode "blob". The kernel runs in kernel mode and 3827 the applications run in user mode (with the MPU restricting user 3828 mode accesses). Access to the kernel from the user blob is only 3829 via system calls (SVCalls). 3830 - Extensive changes were made to the syscall, SVCall, and trapping 3831 logic. Many internal interfaces were renamed. 3832 - The memory manager was extended to support both kernel- and user- 3833 mode allocations. Logic within the kernel needs to use the 3834 correct kernel- or user-space allocator, depending upon the user 3835 of the allocated memory. 3836 - The user-space blob now contains a header built in at the beginning 3837 of the block that provides the same information that was previously 3838 provided by a kludgy, auto-generated header file (user_map.h). 3839 - Basic support implemented for the ARMv7-M family with fragments 3840 also implemetned for the ARMv6-M and MIPS32 families. 3841 - Kernel build supported added for the LPC17xx Open1788 and for 3842 the Atmel SAM3U-EK board. All testing is being performed on the 3843 Open1788 board. 3844 3845 * Signals: 3846 3847 - Delivery of signals to threads within a task group is now compatible 3848 with the way that signals are delivered to threads within a process. 3849 3850 * Drivers: 3851 3852 - Add a driver for the SST29VF NOR FLASH parts. 3853 - USB device trace/debug feature extended to decode device-specific 3854 trace events to make the trace output more readable (from Petteri 3855 Aimonen). 3856 - USB MSC device driver can not support names of differing sizes 3857 in the USB descriptor and the SCSI fields (from Petteri Aimonen). 3858 - Locking added to MMC/SD SPI drivers so that MMC/SD can co-exist on 3859 the same bus as other SPI devices. Frequency is reset each time 3860 that the MMC/SD SPI has the bus locked. (from Petteri Aimonen). 3861 3862 * ARMv6-M (Cortex-M0): 3863 3864 - Added support for the ARM Cortex-M0 family. 3865 3866 * nuvoTon NUC120: 3867 3868 - Added support for the nuvoTon NUC120 MCU (Cortex-M0). 3869 3870 * nuvoTon NUC120 Boards: 3871 3872 - Added basic support for the nuvoTon NuTiny-SDK-NUC120 board (Cortex-M0). 3873 3874 * LPC17xx: 3875 3876 - Added support for the LPC177x and LPC178x families. Most of this is 3877 the work of Rommel Marcelo. 3878 3879 * LPC17xx Boards: 3880 3881 - Added support for Zilogic System's ARM development Kit, ZKIT-ARM-1769. 3882 From Rashid. 3883 - The port for the WaveShare Open1788 board is now functional. Basic 3884 OS test and NuttShell (NSH) configurations are functional. More 3885 driver development and testing is needed (from Rommel Marcelo). 3886 3887 * LPC17xx Drivers: 3888 3889 - Added an SD card MSI driver for the LPC178x. The driver is marginally 3890 functional but requires DMA capability to be reliable. 3891 3892 * STM32 3893 3894 - Support extended to handle the STM32 F3 family (Cortex-M4 with F1-like 3895 peripherals). 3896 3897 * STM32 Boards 3898 3899 - Added support the STMicro STM32F3Discovery board (STM32 F3). 3900 3901 * Stellaris LM3S/LM4F 3902 3903 - Basic support for the LM4F120 family is in place, but untested (mostly 3904 from Jose Pablo Carballo). 3905 3906 * Stellaris LM4F Boards 3907 3908 - Add support for the LM4F120 LaunchPad (untested). 3909 3910 * Networking: 3911 3912 - select() should now allocate a little less memory. 3913 3914 * Memory Management: 3915 3916 - Extended to support multiple heaps. This is used as part of 3917 the kernel build in order to support separater user- and 3918 kernel-mode heaps. 3919 - The stand-alone memory manger test had to be removed. It 3920 was too entangled and made extension of the memory manager 3921 nearly impossible. This is a loss. 3922 3923 * Build System: 3924 3925 - Several configurations converted to use the kconfig-frontends 3926 configuration tool. There are still many more that need to 3927 be converted. 3928 3929 * C Library: 3930 3931 - Move the workqueue logic into the C library. There is now a 3932 special user-space version of the work queue (which will only 3933 be used with a NuttX kernel build). 3934 - Implementation of itoa() contributed by Ryan Sundberg. 3935 3936 * Applications: 3937 3938 - The NSH builtin task logic now uses task_spawn() to start builtin 3939 applications. 3940 - The OS test now includes a test cased to verify task_restart(). 3941 3942Efforts In Progress. The following are features that are partially 3943implemented but present in this release. Most are expected to be fully 3944available in NuttX 6.27. 3945 3946 * LM4F120 LaunchPad port. Code is in place, but nothing has been tested. 3947 3948 * WaveShare Open1788 port. This port as actually complete and 3949 functional. However, there is still ongoing development and 3950 testing of drivers. 3951 3952 * Kernel Build. Much progress has been made, but there kernel build is 3953 not yet fully functional due to several user resources that are not yet 3954 properly disentangled from the kernel blob. 3955 3956 * Conversion of old configurations to use the kconfig-frontends 3957 tool is an ongoing effort that will continue for some time. 3958 3959Bugfixes (see the ChangeLog for details). Some of these are very important: 3960 3961 * Tasking: 3962 3963 - The wrong PID was being signalled with SIGCHILD. It should be 3964 the PID of the task that create the task group, not the ID of 3965 the last thread to leave the task group. 3966 - Added logic so that some internal resources and states are recovered 3967 when tasks are deleted or restarted. Handle cases where there are 3968 outstanding timed events pending when tasks are deleted or restarted. 3969 3970 * ARMv7-M: 3971 3972 - Several fixes to the MPU control logic. 3973 3974 * Drivers: 3975 3976 - Removable serial drivers race conditions fixed. 3977 - MAX11802 timing bug (from Petteri Aimonen). 3978 3979 * STM32 Drivers: 3980 3981 - Handle cases were SPI DMA logic fails if sem_wait is awakened 3982 by a signal. Need to clear error flags to prevent corruption of 3983 subsequent transfers. Also, bit count should not be changed while 3984 the SPI peripheral is enabled (from Petteri Aimonen). 3985 - Fixes to the OTG FS device driver from Petteri Aimonen. 3986 - Fix typos in DMA register header file (from Yan T.) 3987 3988 * Graphics: 3989 3990 - Correction to the hyphen in the SANS 17x22 font (from Petteri 3991 Aimonen). 3992 3993 * Networking: 3994 3995 - Corrected errors in the socket poll/select logic. Additional 3996 state logic was needed to detect if the socket is still connected 3997 before starting the poll wait. (bug reported by Qiang Yu). 3998 3999 * Memory Management: 4000 4001 - mallinfo() should hold the memory manager semaphore (from Petteri 4002 Aimonen. 4003 4004 * Build System: 4005 4006 - Resolved several build errors reported by Mike Smith. 4007 4008 * Applications: 4009 4010 - Fixed an NSH memory leak: Needed to detach after creating each 4011 pthread. 4012 - readline() now returns EOF on any failure (instead of a negated 4013 errno value). This is because the underlying read is based on 4014 logic similar to getc. The value zero (meaning end-of-file) 4015 was being confused with a NUL. So if a NUL was received, the 4016 NSH session would terminate because it thought it was the end of 4017 file. 4018 4019NuttX-6.27 4020---------- 4021 4022The 94th release of NuttX, Version 6.27, was made on April 28, 2013, 4023and is available for download from the SourceForge website. Note 4024that release consists of two tarballs: nuttx-6.27.tar.gz and 4025apps-6.27.tar.gz. Both may be needed (see the top-level nuttx/README.txt 4026file for build information). 4027 4028Additional new features and extended functionality: 4029 4030 * OS Initialization: 4031 4032 - Add missing registration of /dev/zero. Registration of /dev/null 4033 should depend upon conditional compilation. From Ken Pettit. 4034 4035 * Tasking: 4036 4037 - Added a new interface to set aside memory on the task's stack. This 4038 is used (at least in the kernel build) to hold task arguments. 4039 - Remove up_assert_code(). One assertion routine is enough. 4040 4041 * Kernel Build: 4042 4043 - Extensive changes were made to support the kernel build mode. In 4044 this mode, NuttX is built as a monolithic kernel. NuttX is built 4045 as a separate kernel mode "blob" and the applications are built 4046 as a separate user mode "blob". The kernel runs in kernel mode and 4047 the applications run in user mode (with the MPU restricting user 4048 mode accesses). Access to the kernel from the user blob is only 4049 via system calls (SVCalls). 4050 - Kernel build configurations for the Open1788 board and for the 4051 STM32F4Discovery now execute correctly. 4052 - Changes were made to task and thread start-up routines, signal 4053 handling, data structures, ARMv7-M SVCalls, stack management 4054 interfaces, 4055 4056 * Drivers: 4057 4058 - Driver for the ST7567 LCD Display Module from Univision Technology 4059 Inc. Contributed by Manikandan.S 4060 - SPI initialize functions renamed so that multiple SPI blocks can 4061 be initialized. 4062 - Extended to support the RAMTRON FM25V01 device. Contributed by 4063 Lorenz Meier 4064 - Serial drivers: TIOCSERGSTRUCT ioctls now conditioned on 4065 CONFIG_SERIAL_TIOCSERGSTRUCT 4066 4067 * ARMv7-M (Cortex-M3/4): 4068 4069 - Added support for modifiable interrupt vectors in RAM 4070 4071 * nuvoTon NUC1xx: 4072 4073 - Added kernel build support 4074 4075 * Freescale Kinetis: 4076 4077 - Add kernel build support 4078 - Add support for the Kinetis L family of Cortex-M0+ MCUs. Contributed 4079 by Alan Carvalho de Assis. 4080 4081 * LPC17xx: 4082 4083 - Now holds off sleep mode in the IDLE loop is DMA is in progress 4084 (because sleep mode will disable CPU SRAM). 4085 4086 * LPC17xx Boards: 4087 4088 - ZKIT-ARM-1769: Now supports the ST7567 LCD display module. Added 4089 an nxhello configuration for testing (Manikandan.S). 4090 - ZKIT-ARM-1769: Add support for both CAN1 and CAN2. Contributed by 4091 M.Kannan 4092 4093 - Open1788: Basic support for the WaveShare Open1788 board is complete 4094 with working OS test, NSH, and graphics configurations. 4095 - Open1788: Integrated the LPC178x LCD driver with the WaveShare display. 4096 Touchscreen support is included, howerver, there appears to be an 4097 issue with the Open1788 touchscreen interrupt signal. 4098 - Open1788: Now supports SDRAM (used to provide the LCD framebuffer). 4099 - Open 1788: Reversed sense of the IDLE LCD. It is now off when the 4100 LPC17 is sleeping and on when awake. That is much a better visual 4101 indication of the dynamic CPU load 4102 4103 * LPC17xx Drivers: 4104 4105 - Added an LCD framebuffer driver for the LPC177x/8x family. 4106 - Implemented LPC17xx GPDMA support. 4107 - Integrated the LPC17xx GPDMA support into the SD card driver. 4108 - SSP driver adapted to work with the LPC178x family. 4109 - Separate LPC176x and LPC178x GPIO logic; this logic is too different 4110 to maintain in one file with conditional compilation. 4111 - Re-design of the GPIO logic for the LPC178x family by Rommel Marcelo. 4112 4113 * LPC43xx: 4114 4115 - Added kernel build support 4116 4117 * STM32: 4118 4119 - Added support for kernel mode build. 4120 - Added architecure support for the STM32 F427/F437 chips. Contributed 4121 by Mike Smith 4122 4123 * STM32 Boards: 4124 4125 - Added a configuration to support a kernel mode build of the OS test 4126 on the STM32F4Discovery 4127 4128 * Stellaris LM3S/LM4F: 4129 4130 - Added kernel build support 4131 - Added support for the 7 UARTs on the LM4F120 4132 4133 * Stellaris LM4F Boards: 4134 4135 - Added scripts and instructions to simplify use of OpenOCD with ICDI 4136 (JP Carballo) 4137 - The basic for the Stellaris LM4F120 Launchpad is complete. This 4138 includes support for OS test and NSH configurations. Additional 4139 driver development is needed. 4140 4141 * Build System: 4142 4143 - Directories where the same sources files are used to build different 4144 objects in the first and second pass kernel builds need to keep those 4145 objects in separate directories so that they are not constantly 4146 rebuilt. 4147 4148 * Applications: 4149 4150 - apps/system/ramtest: Add a simple memory test that can be built 4151 as an NSH command. 4152 4153 * Tools: 4154 4155 - kconfig2html is a new tool which will replace the hand-generated 4156 documentation of the NuttX configruation variables with auto- 4157 generated documentation. 4158 4159Efforts In Progress. The following are features that are partially 4160implemented but present in this release. Most are expected to be fully 4161available in NuttX 6.28. 4162 4163 * A port to the Freescale Freedom KL25Z is complete but not yet stable 4164 enough. The KL25Z is a low-cost Cortex-M0+ part with 128KB of FLASH 4165 and 16KB of SRAM. This is is the effort of Alan Carvalho de Assis. 4166 4167 * Conversion of old configurations to use the kconfig-frontends 4168 tool is an ongoing effort that will continue for some time. 4169 At this time, only 32% of the configurations have been converted 4170 to use the kconfig-frontends tools. 4171 4172Bugfixes (see the ChangeLog for details). Some of these are very important: 4173 4174 * Tasking: 4175 4176 - Fixed a critical bug: When there is pending C buffered output 4177 and the system is very busy, the a pthread may be blocked at 4178 a critical point when trying to exit. Blocking at this critical 4179 point would cause crashes. All entire task/thread exit logic 4180 paths were reviewed and failsafe mechanisms were put in place 4181 to assure that exitting tasks never block after task teardown 4182 has been started. 4183 4184 * ARMv6-M: 4185 4186 - Fixed parameter passing for all system call inline functions with > 3 4187 parameters 4188 - Fixed a major problem: The Cortex-M0 has no BASEPRI register but the 4189 logic of NuttX-6.26 was using it to manage interrupts. Switch to 4190 using the PRIMASK instead. This means that hardfaults will (again) 4191 occur when SVC instructions are executed 4192 4193 * ARMv7-M: 4194 4195 - Corrected Correct MPU sub-region settings for unaligned regions. 4196 - In exception handling with CONFIG_NUTTX_KERNEL, need to explicitly 4197 set and clear the privilege bit in the CONTROL 4198 - Fixed parameter passing for all system call inline functions with > 3 4199 parameters 4200 4201 * Drivers: 4202 4203 - Support for O_NONBLOCK was not supported in the "upper half" 4204 serial driver. 4205 - PL2303 compilation errors 4206 4207 * Stellaris LM3S/4F: 4208 4209 - Corrected typos in alternate function definitions. 4210 4211 * LPC17xx Drivers: 4212 4213 - Added a work-around for an ADC errata. From Chris Taglia 4214 - Only one ADC pin was configured. Need to configure all that 4215 are in the ADC0 set. From MKannan 4216 4217 * File Systems: 4218 4219 - The FAT logic was not making a distinction between directory 4220 non-existence and file non-existence so when it you try to 4221 create a file in a non-existent directory, it would create a 4222 file with the name of the missing directory. Reported by Andrew 4223 Tridgell 4224 - Several fixes to the FAT file system from Ronen Vainish. These 4225 fixes mostly involve the logic to extend directory clusters for 4226 the case of long file names but also include a few important 4227 general fixes (such as for storing 32 bit FAT values) 4228 - mkfatfs was writing the boot code to the wrong location. From 4229 Petteri Aimonen 4230 4231 * Networking: 4232 4233 - Fixed a compilation error when socket options are are disabled. 4234 Reported by Daniel O'Connor 4235 4236 * C Library: 4237 4238 - Corrected an error in sscanf. If %n occurs in the format statement 4239 after the input data stream has been fully parsed, the %n format 4240 specifier will not be handled. Reported by Lorenz Meier 4241 - strchr(str, '\0') should return a pointer to the end of the string, 4242 not NULL. From Petteri Aimonen 4243 4244 * Build System: 4245 4246 - Fix naming of NuttX target if EXEEXT is defined. 4247 4248 * Applications: 4249 4250 - OS test: Fix timing error in non-cancelable thread test. 4251 - NSH: Correct the test of the skip input parameter. Was limiting the 4252 range to <= count. From Ken Petit. 4253 4254NuttX-6.28 4255---------- 4256 4257The 95th release of NuttX, Version 6.28, was made on June 14, 2013, 4258and is available for download from the SourceForge website. Note 4259that release consists of two tarballs: nuttx-6.28.tar.gz and 4260apps-6.28.tar.gz. Both may be needed (see the top-level nuttx/README.txt 4261file for build information). 4262 4263Additional new features and extended functionality: 4264 4265 * File Systems: 4266 4267 - SMART FLASH file system (contributed by Add Ken Pettit). 4268 4269 * MTD (FLASH) Drivers: 4270 4271 - Add support of MTD partitions via a new MTD driver that manages a 4272 set of MTD devices, each managing a subset of the FLASH region 4273 managed by the parent MTD driver. 4274 - Extended the MTD interface to provide an (optional) method to 4275 perform byte oriented writes if supported by the FLASH part. 4276 - M25Px driver re-architected to use the byte write capability (when 4277 possible) and to use 4KB sectors for the erase block size when the 4278 part supports it (from Ken Pettit). 4279 4280 * LCD Drivers: 4281 4282 - New interface definitions to support audio devices (from Ken Pettit) 4283 and alphanumeric, segment LCDs. 4284 4285 * Wireless Drivers: 4286 4287 - Added new driver for the wireless nRF24L01+ transceiver (from 4288 Laurent Latil). 4289 4290 * Calypso: 4291 4292 - Added support for the Pirelli DP-L10 phone (from Craig Comstock via 4293 Alan Alan Carvalho de Assis) 4294 4295 * STM32: 4296 4297 - Added an option to conditionally disable the "wfi" sleep mode. This 4298 is needed with certain JTAG debuggers to prevent the debug session 4299 from being disconnected (from Ken Pettit). 4300 - Added support for the STM32L (STM32L15X/STM32L16x) family. 4301 - Added STM32F103C4 and F103C8 chip support (from Laurent Latil). 4302 - Added a new interface function, stm32_dmacapable() that can be used 4303 to determine if DMA is possible from the specified memory address 4304 (from Petteri Aimonen) 4305 4306 * STM32 Drivers: 4307 4308 - If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses 4309 stm32_dmacapable() to determine if it is possible to perform DMA 4310 from the specified address. This change is important for the STM32 4311 F4 which may have SPI data buffers allocated on the stack in CCM 4312 memory which cannot support the DMA (from Petteri Aimonen). 4313 4314 * STM32 Boards: 4315 4316 - Support added for the MikroElektronika Mikromedia for STM32F4 4317 development board (from Ken Pettit) with the MIO283QT2 LCD and 4318 touchscreen. Several graphics configurations are included. 4319 - The HY-mini STM32v board now uses the common SSD1289 driver 4320 and supported the card detect interrupt. Several new 4321 configurations also added and some removed (from Laurent Latil). 4322 - Support added for the R65105-based LCD that comes with some 4323 HY-Mini STM32v boards (from Christian Faure). 4324 - Added basic support for the STM32L-Discovery board. Drivers 4325 for the on-board segment LCD are included. 4326 - Added support for the STM32 Tiny development board based on the 4327 STM32 F103C8T6 MCU. This includes support for the nRF24L01+ 4328 wireless on the board (from Laurent Latil). 4329 4330 * Stellaris LM3S/LM4F: 4331 4332 - Support added for a TI/Stellaris internal FLASH MTD driver (from Max 4333 Holtzberg). 4334 4335 * Stellaris LM4F Boards: 4336 4337 - The LM3S6965-EK now has configurations for the UDP discovery tool and 4338 for the TCP echo server (both from Max Holtzberg) 4339 4340 * Atmel ATSAM3/4: 4341 4342 - Reorganized, renamed, and updated directory structure to better 4343 support additional members of the SAM3/4 family. 4344 - Added support for both the ATSAM4S and ATSAM4L families. The 4345 ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a 4346 different beast, really much more akin to the AVR32s SoCs but 4347 with a Cortex-M4. 4348 4349 * Atmel ATSAM3/4 Boards: 4350 4351 - Added support for the Atmel SAM4L Xplained Pro development board. 4352 This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH + 4353 32KB SRAM). 4354 - Added support for the Atmel SAM4S Xplained developement board. This 4355 board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB 4356 SRAM). 4357 4358 * PIC32MX Boards: 4359 4360 - Added support for the 1602 segment LCD on-board the Sure PIC32MX 4361 board. This board will now also support a USB NuttX console and 4362 the USB monitor test program. 4363 4364 * Build System: 4365 4366 - Clean-up of almost all .gitignore files: Made scope of ignore to be 4367 only the current directory; Ignore .dSYM files in directories where 4368 .exe's may be built. Also, in Makefiles, clean .dSYM files in 4369 directories where an .exe may be built. 4370 - Standardize and consolidated all build-as-an-NSH-application 4371 configuration settings. Now only CONFIG_NSH_BUILTIN_APPS is 4372 sufficient to build an application, test, or or example as an NSH 4373 builtin application. 4374 - Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI 4375 toolchains. 4376 4377 * Libraries: 4378 4379 - Added encoder/decoder logic to marshal and serialize special segment 4380 LCD (SLCD) commands intermixed with normal ASCII data. This is the 4381 similar to the encoding/decoding logic that is used to marshal 4382 special commands from a keyboard. 4383 - Add dprintf() and vdprintf() (the latter from Andrew Tridgell). 4384 - Add an application that may be built as an NSH builtin command that 4385 will erase FLASH using a flash_eraseall NSH command (from Ken Pettit). 4386 4387 * Applications: 4388 4389 - Added an MTD partition test/examples. Currently used with (1) the a 4390 simulation configuration to test MTD partitions on a RAM emulation 4391 of FLASH and (2) with the Mikroe STM32F4 configuration. 4392 - Added a test/example to verify alphanumeric, segment LCDs. 4393 - Added a simple single threaded, poll based TCP echo server based 4394 on W. Richard Stevens UNIX Network Programming Book (from Max 4395 Holtzberg). 4396 - Added several tests of the SMART block driver and file system (from 4397 Ken Pettit). 4398 - Added a runtime configuration for the UDP discover utility (from 4399 Max Holtzberg). 4400 - Added an example application to demo the nRF24L01 driver (from 4401 Laurent Latil). 4402 - New and modified NSH commands: 4403 Added a -h option to the df command to show the volume information 4404 in human readable form (from Ken Petit). 4405 Add a new mksmartfs command (from Ken Petit). 4406 4407Efforts In Progress. The following are features that are partially 4408implemented but present in this release. Most are expected to be fully 4409available in NuttX 6.28. 4410 4411 * Audio System: 4412 4413 - A complete audio subsystem include CODECs, higher level management, 4414 interface definitions, and audio drivers was contributed by Ken 4415 Pettit. This work has not been completely verified as of this 4416 release and so is categorized as a work-in-progress. At present, 4417 progress is blocked due to issues interfacing with the VS1053 4418 audio DAC on the Mikroe STM32F4 board. 4419 4420 * kconfig-fronted Configuration: 4421 4422 - Conversion of old configurations to use the kconfig-frontends 4423 tool is an ongoing effort that will continue for some time. 4424 At this time, only 43% of the configurations have been converted 4425 to use the kconfig-frontends tools. 4426 4427Bugfixes (see the ChangeLog for details). Some of these are very important: 4428 4429 * Tasking: 4430 4431 - Modify assertion in the priority inheritance logic that is reported 4432 to cause false alarm assertions. 4433 4434 * Kernel Build: 4435 4436 - Typo in syscall proxying logic corrected by Ken Pettit. 4437 4438 * Networking: 4439 4440 - Poll setup/teardown logic should ignore invalid (i.e., negative) 4441 file descriptors (from Max Holtzberg). 4442 - When readahead data is available, the network poll() logic should 4443 set POLLIN (or POLLRDNORM), not POLLOUT (from Max Holtzberg). 4444 4445 * LCD Drivers: 4446 4447 - Correct power controls in the MIO283QT2 LCD driver. 4448 4449 * USB Device Controller Drivers: 4450 4451 - Change the default IN request buffer size from 64 to 96. This will 4452 avoid requests of exactly MAXPACKET size and, hence, avoid so many 4453 NULL packets. Also, fix the OUT request buffers size to exactly the 4454 max packet size. It really cannot be any other size. 4455 4456 * STM32 Drivers: 4457 4458 - Correct some bad STM32 F1 DMA definitions that crept into the system 4459 a few months ago a broke STM32 F1 DMA (from Laurent Latil) 4460 - Fixed an error in NULL packet handling in the STM32 F1 USB device 4461 controller driver: If the NULL-packet needed flag ever got set, 4462 then it was not being cleared and infinite NULL packets resulted. 4463 This only affects the CDC/ACM class and was the cause of the 4464 failures using the USB CDC/ACM device as a NuttX console. With this 4465 change the USB works well as an alternative NuttX console device for 4466 the STM32 F1 family. 4467 - Correct some bad condition compilation in the RCC logic (CONFIG_ 4468 missing from setting names). This affects some STM32 FLASH pre- 4469 fetch settings (from Lorenz Meier). 4470 - Change for hardware flow control support for STM32. The change also 4471 fixes incorrect operation of USART2 and UART5 in current master 4472 (from Lorenz Meier and Mike Smith). 4473 - Fixed a backward conditional in USB OTG FS host controller driver 4474 that prevented detection of disconnection events (from Scott). 4475 4476 * LPC17xx Drivers: 4477 4478 - I2C interrupt control. Also correction for a single byte read 4479 timeout error (from M. Kannan). 4480 4481 * Freescale Kinetis: 4482 4483 - Freedom KL25Z pin multiplexing and LED control corrections (from 4484 Alan Carvalho de Assis) 4485 4486 * PIC32MX: 4487 4488 - Fix NULL packet handling in the PIC32 USB device driver. Without 4489 this fix the CDC/ACM driver cannot be used reliably with the PIC32 4490 USB. With this change the USB works well as an alternative NuttX 4491 console device. 4492 4493 * Graphics: 4494 4495 - Default priorities for NxWidget and NxWM threads should be 100, 4496 not 50, to be consistent with other default priorities. 4497 4498 * Applications: 4499 4500 - Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN option from the NXTEXT 4501 example. The test logic was bad for the case where this options is 4502 not selected. Also, completed the empty Kconfig file. 4503 - C++ name mangling was occurring when this example is built as an NSH 4504 built-in application causing the entry to be undefined when called 4505 from C code. 4506 - Add some missing NSH library configuration values (from Lorenz 4507 Meier). 4508 4509NuttX-6.29 4510---------- 4511 4512The 96th release of NuttX, Version 6.29, was made on July 31, 2013, 4513and is available for download from the SourceForge website. Note 4514that release consists of two tarballs: nuttx-6.29.tar.gz and 4515apps-6.29.tar.gz. Both may be needed (see the top-level nuttx/README.txt 4516file for build information). 4517 4518Additional new features and extended functionality: 4519 4520 * Drivers: 4521 4522 - Generalized the SSD1306 driver and added support UG-2832HSWEG04 4523 which is very similar to the existing support for the 4524 UG-2864HSWEG01. 4525 - Added support for a generic bit-bang SPI driver. This includes 4526 both a common "upper half" driver as well as a platformp-specific 4527 "lower half" dirvers based on a common "template." 4528 4529 * ARMv7-A, Cortex-A5 4530 4531 - Added support for the ARMv7-A architecture and the Cortex-A5 in particular. 4532 4533 * ARMv7-M, Cortex-M3/4 4534 4535 - Modified how some registers are copied during a context switch (with 4536 lazy FPU register saving). This should save some context switching 4537 time when the context switch is due to interrupt level processing. 4538 4539 * STM32: 4540 4541 - Added support for a separate CCM heap. This may be useful for 4542 segregating allocations for CCM (which cannot be used for DMA) 4543 from other allocations (that may be used used for DMA). 4544 4545 * STM32 Drivers: 4546 4547 - DAC: Added support for DAC DMA (contributed by John Wharington). 4548 - I2C: An I2C driver for the STM32 F3 family (from John Wharington). 4549 4550 * Atmel AT91 SAM/4: 4551 4552 - Add support for SAM3X and SAM3A chips 4553 4554 * Atmel AT91 SAM/4 Drivers: 4555 4556 - Re-architect the SAM3/4 SPI driver so that is it compatible with the 4557 SPI drivers of other MCUs. 4558 - Added register definition file for the SAM4L LCD peripheral. 4559 - Added SAM4L PDCA register definition file 4560 4561 * Atmel AT91 SAM/4 Boards: 4562 4563 - SAM4L-Xplained: Added support for the SPI-based SD card on the I/O1 4564 module. 4565 - SAM4L-Xplained: Added a driver for the LED1 segment LCD module. 4566 - SAM4L-Xplained: Added support for the UG-2832HSWEG04 OLED on the 4567 SAM4L Xplained Pro's OLED1 module 4568 - SAM4S-Xplained: Added support for on-board 1MB SRAM 4569 - Arduino Due: Basic support for the Arduino Due (SAM3X) is now 4570 included. 4571 - SAM3U-EK: The touchscreen is now functional. 4572 4573 * Atmel AT91 SAMA5D3 4574 4575 - Added support for the Atmel AT91SAMA5D3 Cortex-A5 chip family. 4576 4577 * Atmel AT91 SAMA5D3 Boards 4578 4579 - Added support for the Atmel SAMA5D3x-EK boards which use the AT9 4580 SAMA5D3x chips (x=1,3,4,5). 4581 4582 * Freescale KL25Z Drivers 4583 4584 - Freescale KL25Z TSI register definitions and example TSI driver for 4585 the Freedom KL25Z board from Alan Carvalho de Assis. 4586 - Added SPI driver and register definitions for the Freescale KL25Z. 4587 - Added a framework for controlling SPI-related discrete inputs and 4588 outputs. Taken from work by Alan Carvalho de Assis 4589 4590 * Build System: 4591 4592 - New sub-directories to hold SPI-related files: includes/nuttx/spi.h 4593 moved to include/nuttx/spi/.; SPI-related Kconfig info moved from 4594 drivers/Kconfig to drivers/spi/kconfig. 4595 - Finally... I changed the naming of configuration variables like 4596 CONFIG_DRAM_ to CONFIG_RAM_. This has bothered me for a long time 4597 since most boards don't have DRAM. The more generic RAM naming 4598 should not produce so much cognitive dissonance 4599 4600 * Libraries: 4601 4602 - Added CRC16 support. 4603 4604 * Applications: 4605 4606 - Added Zmodem file transfer support. This may be used as an embedded 4607 library or may be built as 'sz' and 'rz' commands that can be 4608 executed from NSH. 4609 - C++ initializers should be set once and, preferably, in the context 4610 of the task that uses any C++ statically initialized classes. This 4611 only becomes an issue if cxxtest or helloxx are built as NSH builtin 4612 applications. Then you want the initialization done in cxxtext or 4613 helloxx and not in NSH (and certainly not twice). Added 4614 configuration options to control who does the C++ initialization. 4615 NSH now does not do C++ initialization be default and must be 4616 configured to do otherwise. Conversely, cxxtest and helloxx 4617 will always do C++ initialization unless configured do otherwise. 4618 - examples/cxxtext: Add ostream test as provided by Michael. 4619 - NSH: Added a 'cmp' command that can be used to compare two files 4620 for equivalence. Returns an indication if the files differ. 4621 Contributed by Andrew Tridgell (via Lorenz Meier). 4622 4623Efforts In Progress. The following are features that are partially 4624implemented but present in this release. They are not likely to be 4625completed soon. 4626 4627 * Audio System: 4628 4629 - A complete audio subsystem include CODECs, higher level management, 4630 interface definitions, and audio drivers was contributed by Ken 4631 Pettit. This work has not been completely verified as of this 4632 release and so is categorized as a work-in-progress. At present, 4633 progress is blocked due to issues interfacing with the VS1053 4634 audio DAC on the Mikroe STM32F4 board. 4635 4636 * kconfig-fronted Configuration: 4637 4638 - Conversion of old configurations to use the kconfig-frontends 4639 tool is an ongoing effort that will continue for some time. 4640 At this time, only 45% of the configurations have been converted 4641 to use the kconfig-frontends tools. 4642 4643Bugfixes (see the ChangeLog for details). Some of these are very important: 4644 4645 * File Systems: 4646 4647 - Fixed compilation error if no file systems are enabled: Change 4648 error to ERROR. 4649 - Read-Ahead/Write buffering: Correct typos that can cause failures 4650 in some configurations (From Chia Cheng Tsao). 4651 4652 * Drivers 4653 4654 - Remove the wait for the touchscreen busy bit in the ADS7843E driver. 4655 From my reading of the ADS7843 spec, it would not be appropriate to 4656 wait for the BUSY bit to de-asserted anyway (since it is only de- 4657 asserted when we read the data). Most boards do not even bother to 4658 provide the BUSY bit. 4659 - MMC/SD SPI based driver: Driver needs to make sure that the SPI 4660 mode and data width are correct. 4661 - ENC28J60: Change buffer ordering to work around Errata. From Dave 4662 (ziggurat29). 4663 4664 * USB Device Controller Drivers: 4665 4666 - Fixed a typo in the composite device driver unitialization logic. 4667 DEV1 should be DEV2 in one case. 4668 - usbdev.h: Fix some typos that cause compiler errors when 4669 CONFIG_USBDEV_DMA and CONFIG_USBDEV_DMAMEMORY are selected (From 4670 Chia Cheng Tsao). 4671 4672 * ARM9: 4673 4674 - Fix a bug (uninitialized register error) that crept in the ARM9 4675 boot-up code several years ago. Obviously no one has used the 4676 ARM9 NuttX port for years! 4677 4678 * STM32 Drivers: 4679 4680 - Fix STM32 OTF FS endpoint allocation logic. Apparently the same 4681 endpoint can be allocated as both an IN or an OUT endpoint. The 4682 existing implementation only supported one allocation, either IN or 4683 OUT. This resulted in failures to allocate endpoints when used with 4684 the CDC/ACM + MSC composite driver (From Chia Cheng Tsao). 4685 - SDIO: Add support for the data block end (DBCKEND) interrupt to 4686 terminate transfers (From Chia Cheng Tsao). 4687 - DAC: Fixed numerous DAC driver errors and added support for DAC 4688 DMA (contributed by John Wharington). 4689 4690 * SAM3/4: 4691 4692 - SAM4S: Correct configuration of PIO pins for SAM4S B and C peripherals. 4693 - Need to disable write protection before configuring PIO pins. 4694 - GPIO configuration logic must protect against re-entrancy. 4695 - Clocking must be applied to the SMC module for the 3X and 3A family in 4696 order for the NFC SRAM to be functional. 4697 - Fixed some errors for interrupts on ports D-F. 4698 4699 * SAM3/4 Drivers: 4700 4701 - Common SPI driver: Fix SPI mode setting. In the SAM3/4 family, the 4702 clock phase control (CPHA) is inverted (NPHA). Also fixed an 4703 incorrect pointer test. Was checking if the wrong pointer was NULL. 4704 4705 * SAM3/4 Boards: 4706 4707 - SAM3U-EK: Fix polarity of the /PENIRQ signal (it is active low). 4708 The SAM3U-EK board now runs at 96MHz. 4709 4710 * Applications: 4711 4712 - apps/examples/nxhello: Minor fix for compilation error when the 4713 display resolution is low (< 8bpp) due to a typo that has been there 4714 for a long time. Also Correct default colors when in Y1 code mode. 4715 - apps/system/ramtest: The RAM test was not correctly built 4716 into the configuration and build system. 4717 - apps/examples/composite: Change to prevent some false alarm debug 4718 assertions (From Chia Cheng Tao). 4719 4720NuttX-6.30 4721---------- 4722 4723The 97th release of NuttX, Version 6.30, was made on September 14, 2013, 4724and is available for download from the SourceForge website. Note 4725that release consists of two tarballs: nuttx-6.30.tar.gz and 4726apps-6.30.tar.gz. Both may be needed (see the top-level nuttx/README.txt 4727file for build information). 4728 4729Additional new features and extended functionality: 4730 4731 * Common Drivers: 4732 4733 - Extended TERMIOS support for serial and CDC/ACM drivers. From 4734 Mike Smith, Andrew Tridgell and Lorenz Meier. 4735 - Added option to disable serial port reordering. From Lorenz Meier. 4736 - Several changes to the USB host control interface and extensions to 4737 common USB host logic to handle host controllers with multiple 4738 downstream ports in the root hub. 4739 - USB device tracing: Extended decoding and stringifying of USB trace 4740 output to include trace output from class drivers. 4741 - USB host tracing: Added support for USB host tracing similar in 4742 some ways to USB device tracing: Stringification is an inherent 4743 part of the trace decoding (not an option). Only available in the 4744 SAMA5 USB host drivers now. 4745 4746 * Networking / Network Drivers 4747 4748 - Support for the Microchip ENCX24J600 Ethernet driver from Max 4749 Holtzberg 4750 - CC3000 Networking. Initial support for the TI CC3000 network 4751 module on the Freescale Freedom-KL25Z board from Alan Carvalho 4752 de Assis. This is still a work in progress. 4753 4754 * ARMv7-A, Cortex-A5 4755 4756 - Restructured some MMU-related logic and header files. 4757 - Hooks added for Cortex-A8, but not yet used. 4758 4759 * STM32 Drivers: 4760 4761 - STM32 SPI: nbits() interface extended to control bit order as well 4762 as bit width (from Teemu Pirinen) 4763 4764 * STM32 Boards 4765 4766 - Olimex STM32-P107: Incorporate ENCX24J600 networking for the Olimex 4767 STM32 P107 board. 4768 - LeafLabs Maple Board: Add board support for the LeafLabs Maple and 4769 Maple Mini boards. From Librae. 4770 4771 * Atmel AT91 SAMA5D3x 4772 4773 - Added support for the SAMA5 DMAC controllers. 4774 - DMA-capable drivers for the SAMA5 SPI peripherals. 4775 - DMA-capable HSCMCI 0/1/2 drivers. 4776 - Support for PIO interrupts 4777 - Utilities for intelligent conversions between physical and virtual 4778 addresses. 4779 - Added USB host controller drivers for both the OHCI (low- and full- 4780 speed) peripheral and the ECHI (high-speed) peripheral. 4781 - Added USB device controller for the SAMA5 UDPHS peripheral (full- 4782 and high-speed). 4783 - Added a Two Wire (TWI) driver. This is a variant of I2C. 4784 4785 * Atmel AT91 SAMA5D3x-EK Development Boards 4786 4787 - Now supports onboard SDRAM. Modified heap initialization logic 4788 to include SDRAM if configured. 4789 - Integrated a FAT file system on the on-board SPI-based AT25 serial 4790 FLASH 4791 - Integrated HSMCI0 and HSMCI1 support for the microSD and full file 4792 SD card slots. Includes PIO interrupts for card detection events. 4793 - Integrated USB OHCI and ECHI host and high-speed peripheral support. 4794 File system on AT25 now exported via Mass Storage Class. Includes 4795 PIO VBUS controls. 4796 - Integrated the TWI driver and the I2C tool. Added support for an 4797 external AT24 serial EEPROM. 4798 4799 * Applications: 4800 4801 - apps/examples/cc3000. Initial support for the TI CC3000 network 4802 module on the Freescale Freedom-KL25Z board from Alan Carvalho de 4803 Assis. Includes the test to verify the CC3000. 4804 - apps/examples/usbmsc: apps/examples/usbstorage renamed usbmsc for 4805 consistency. Change submitted by CCTSAO. 4806 - apps/system/usbmonitor: The USB monitor has been extended so that 4807 it can be used with USB device or host trace data. 4808 4809Efforts In Progress. The following are features that are partially 4810implemented but present in this release. They are not likely to be 4811completed soon. 4812 4813 * CC3000 Networking 4814 4815 - CC3000 Networking. Initial support for the TI CC3000 network 4816 module on the Freescale Freedom-KL25Z board from Alan Carvalho 4817 de Assis. This is still a work in progress. 4818 4819 * kconfig-fronted Configuration: 4820 4821 - Conversion of old configurations to use the kconfig-frontends 4822 tool is an ongoing effort that will continue for some time. 4823 At this time, only 46% of the configurations have been converted 4824 to use the kconfig-frontends tools. 4825 4826Bugfixes (see the ChangeLog for details). Some of these are very important: 4827 4828 * File Systems: 4829 4830 - ROMFS: Fix an error where long (>15) file names were read 4831 incorrectly from a ROMFS file system. From Mike Smith 4832 - NXFFS: Clean up some compiler warnings. 4833 4834 * Common Drivers 4835 4836 - MMC/SD driver: Correction for a bad return value when multiple 4837 block SDIO transfers are suppressed. By Andrew Tridgell. 4838 - USB HID keyboard and mass storage host-side class drivers: Fix some 4839 compilation errors and warnings when pre-allocated data structures 4840 are used. 4841 - USB device-side class drivers: Fix some compilations errors when 4842 DUALSPEED (i.e., full- and high-sped) support is enabled. 4843 - CDC/ACM and PL2303: Don't use max packetsize assigned to the endpoint 4844 when allocating request buffers; The default value of the endpoint 4845 max packetsize may be incorrect because the endpoint has not yet 4846 been configured. Really only an issue for high-speed endpoints. 4847 - USB Host Mast Storage Class: Fixed a problem that was causing some 4848 devices to fail to initialize: If device is returning fatal transfer 4849 errors while attempting to initialize, don't bother with the startup 4850 retries; abort immediately so that the device will be reset and we 4851 can try again with a better ready device. 4852 - USB Host Mast Storage Class: Correct a reference counting error: 4853 When an MSC device transfer fails while waiting for UnitTestReady, 4854 the reference count on the class was not being decremented. The end 4855 result is a memory leak as can be seen by the USB device numbers 4856 incrementing: sda, sdb, sdc, ... 4857 - USB Device CDC/ACM: Fix backward conditional compilation in the 4858 CDC/ACM driver with regard to remote wakeup and self-powered 4859 capabilities. From the PX4 team via Lorenz Meier, 4860 4861 * Networking / Network Drivers 4862 4863 - ARP IP harvesting: Correct backward condition in netmask task. 4864 From Max Holtzberg. 4865 - Network connection monitor: Fixes a race condition where a loss of 4866 connection may not be detected when the connection is lost before it 4867 has been accepted (from Max Holtzberg). 4868 - TCP/IP Backlog: Fix a critical bug in the TCP/IP backlog 4869 initialization: Only the first backlog buffer was getting added to 4870 the free list. From Max Holtzberg. 4871 - ENC28J60: Fixes and improvements back-ported from the ENCX24J600 4872 to the ENC28J60 by Max Holtzberg. 4873 4874 * STM32 Drivers: 4875 4876 - STM32 I2C fixes for the STM32 F3 family from John Wharington. 4877 - STM32 I2C Correct an error that crept into the STM32 F1 I2C 4878 driver with some recent changes. From Librae 4879 - STM32 F4: Added some missing CONFIG_SERIAL_TERMIOS support; Fixed 4880 some STM32 F4 Timer 8 pin configurations. From CCTSAO. 4881 - STM32 SDIO: If CONFIG_SDIO_BLOCKSETUP defined, OS would crash. Now 4882 Generate an error if CONFIG_SDIO_BLOCKSETUP is defined; that 4883 option is not yet supported by the STM32 SDIO driver. From CCTSAO 4884 - STM32 I2C Timers: Some CCER bit settings changed. Submitted by 4885 CCCTSAO. 4886 - STM32 CAN: Fix access to CAN filter registers. From the PX4 team 4887 via Lorenz Meier. 4888 - STM32 Kconfig: Fix STM32 UART7/8 Kconfig names and UART DMA. From 4889 the PX4 team via Lorenz Meier. 4890 4891 * LPC17xx Drivers 4892 4893 - Fix #endif with missing #if in USB host header file. Reported 4894 by Andrew Bradford, 4895 4896 * SAM3/4 Boards: 4897 4898 - Corrected DMA-related problems: Bad register definitions, parameters 4899 reversed in a function call. 4900 - Correct a race condition in the HSMCI driver when an interrupt 4901 occurs before the wait for the interrupt begins. 4902 - Peripheral clock setup: Correct a typo in a register name. 4903 4904 * Atmel AT91 SAMA5D3 4905 4906 - Order of some operations changed in boot-up logic to defer 4907 enabling of caching of memory regions until SDRAM is initialized. 4908 - Correct handling of spurious interrupts. 4909 4910 * Freescale KL25Z Drivers 4911 4912 - KL25Z SPI: Correct typo in name of a function. From Alan Carvalho 4913 de Assis. 4914 4915 * Applications: 4916 4917 - apps/examples/composite: Fix a typo that can cause a configuration 4918 error. From CCTSAO. 4919 - apps/examples/pwm: Clean-up some configuration confusion. 4920 - apps/netutils/dhcpd/dhcpd.c: Fixed calculation of the next lease 4921 address. From Paolo Messina. 4922 - apps/examples/usbmsc: Don't try to control USB trace if we are 4923 an NSH built-in task. In that case our attempts are inadequate 4924 and only interfere with with other logic that is attempting to 4925 to do the same thing (in NSH or in the USB monitor). 4926 - apps/examples/usbmsc: IMPORTANT bug fix: Change how the msconn 4927 works. Because of recent changes the msconn command was hanging. 4928 This was because the USB MSC start-up logic creates a pthread; 4929 Now waitpid() will wait until all members of the task group 4930 exit. So NSH was hanging in waitpid when msconn started even 4931 though msconn returned. The USB MSC logic really should not use 4932 a pthread, but we are stuck with that for now. The work-around 4933 is the msconn now daemonizes itself so that it so that the pthread 4934 is created in a different task group. 4935 - apps/nshlib: Fix NSH listing output for the case of a single file. 4936 From the PX4 team; provided by Lorenz Meier. 4937 4938NuttX-6.31 4939---------- 4940 4941The 98th release of NuttX, Version 6.31, was made on October 28, 2013, 4942and is available for download from the SourceForge website. Note 4943that release consists of two tarballs: nuttx-6.31.tar.gz and 4944apps-6.31.tar.gz. Both may be needed (see the top-level nuttx/README.txt 4945file for build information). 4946 4947Additional new features and extended functionality: 4948 4949 * General: 4950 4951 - Standardized stack checking logic so the interfaces can be used 4952 by common stack monitoring logic. 4953 4954 * Audio Subsystem and Audio Drivers: 4955 4956 - Ken Pettit has finally released his long awaited audio subsystem. 4957 This is a generic audio subsystem that is appropriate for the 4958 deeply embedded MCU. Current testing has, however, been focused 4959 on the VS1053 CODEC chip. 4960 - Ken Pettit's VS1053 audio CODEC driver is now functional. 4961 4962 * Networking / Network Drivers 4963 4964 - Add the prefix ETH0 to all PHY configuration selections. This 4965 will allow us to support to Ethernet MAC drivers with two different 4966 PHYs (identified with ETH0 and ETH1). Enabled with CONFIG_NETDEV_MULTINIC. 4967 - Add MII/RMII PHY definitions for the Micrel KSZ8051 PHY. 4968 - Add GMII/GRMII PHY definitions for the Micrel KSZ9021/31 PHY. 4969 - New network-optimized, higher-performance sendfile() implementation 4970 from Max Holtzberg. 4971 - Added a simple routing table. This table is currenly only used (1) 4972 when we need to look-up an Ethernet device based on an IP address, 4973 and (2) in the ARP logic when we need to request the MAC address of 4974 the router, vs the MAC address of the peer. 4975 - Make net_close() nonblocking and free unestablished connections if 4976 no free connections available. From Max Holtzberg. 4977 - Changed the meaning of the uip_*input functions. They now return 4978 success when a packet is dropped; This is needed for the ENCX24J600 4979 driver that must make a decision to return the packet or not: It 4980 should not retry dropped packets. From Max Holtzberg. 4981 - David Sidrane has completed integration of the CC3000 networking. 4982 This is much more than a network driver: It is a complete 4983 replacement for the NuttX networking with off-chip networking support 4984 in the CC3000. 4985 - Numerous enhancements to the ENCX24J600 driver from Max Holtberg. 4986 4987 * Other Common Drivers: 4988 4989 - The SST25 serial FLASH MTD driver now includes support for the 4990 SST25VF016B. From David Sidrane. 4991 - Add a preflight method to the SDIO interface to support the STM32 4992 DMA usage model. From Mike Smith. 4993 - Enhanced the MMC/SD SDIO driver to perform DMA preflight operations 4994 and fail DMA read/write requests that fail preflighting. From Mike 4995 Smith. 4996 - Add an ioctl command that can be used to trigger ADC/DAC conversion 4997 under application control. 4998 4999 * File Systems: 5000 5001 - Enhanced the FAT32 filesystem code to understand DMA preflight 5002 failures, and to use the file sector buffer as a bounce buffer when 5003 a user-supplied buffer is not suitable for DMA. From Mike Smith. 5004 5005 * Atmel AT91 SAMA5D3x 5006 5007 - Add support so that subsets of the total DRAM (and other external 5008 memory) can be added to the heap, leaving other memory reserved for 5009 other purposes (like the LCDC framebuffers). 5010 5011 * Atmel AT91 SAMA5D3x Drivers: 5012 5013 - Use more descriptive task names when starting the EHCI and OHCI 5014 monitor tasks. 5015 - Added a 10/100Base-T Ethernet (EMAC) driver. 5016 - Added a 1000Base-T Ethernet (GMAC) driver. 5017 - Added a Real Time Clock (RTC) driver and integrated with the NuttX 5018 system time logic. 5019 - Added support for /dev/random using the SAMA5D3x True Random Number 5020 Generator (TRNG). 5021 - Added a Watchdog Timer (WDT) driver. 5022 - Added a Timer/Counter (TC) library with interface that make be used 5023 by other drivers that need timer support. 5024 - Added an ADC driver that can collect multiple samples using the 5025 sequencer, can be trigger by a timer/counter, and supports DMA data 5026 transfers. 5027 - Added a touchscreen driver based on the special features of the 5028 SAMA5D3 ADC peripheral. 5029 - Added an LCD controller (LCDC) frame buffer driver. 5030 - Added a CAN driver. However, testing has been delayed because of 5031 cabling issues. 5032 - Basic header file support is available for the Image Sensor 5033 Interface (ISI) camera interface. Work on the camera driver is 5034 underway and is expected in the next release. 5035 5036 * Atmel AT91 SAMA5D3x-EK Development Boards 5037 5038 - Add OS test support for the FPU test. 5039 - Enable the task name feature board configuration sto provide 5040 prettier ps command output. 5041 - Added NX and NxWM configurations to verify the LCD and touchscreen. 5042 There are still some outstanding issues with the NxWM configuration 5043 as of this release. 5044 - The TRNG and /dev/random are now enabled by default in the demo 5045 configuration. 5046 5047 * Atmel AT91 SAM3/4 Boards: 5048 5049 - Add configuration to select revision 3 of the Arduino Due which has 5050 some small but important differences. Suggested by gdi@embedders.org. 5051 5052 * STMicro STM32: 5053 5054 - Add support for the STM32F207ZE chip. From Martin Lederhilger. 5055 5056 * STMicro STM32 Boards: 5057 5058 - Add configuration for the Spark Core. The initial check-in is 5059 basically the Maple Mini board and subsequent development by David 5060 Sidrane is his special Spark emulation hardware. The configuration 5061 should be very mature when actual Spark hardware is available. 5062 - Support for the Olimex STM32 P207 board added by Martin Lederhilger. 5063 - Configuration for the Mikroe STM32F4 board configuration updated for 5064 audio support by Ken Pettit. 5065 5066 * NXP LPC17xx Boards: 5067 5068 - zkit-arm-1769: LED1 is now user controllable after booting. From 5069 Rashid Fatah. 5070 5071 * Kinetis KL Drivers: 5072 5073 - PIT and TPM register definitions header files for the from Alan 5074 Carvalho de Assis. 5075 - Added low-level getc() function for operation with no file system. 5076 The KL25Z can now support NSH in a very minimal system that does 5077 not even have a file system. 5078 5079 * Kinetis KL Boards 5080 5081 - A new configuration called minnsh was added is an experiement to 5082 see how small we can get the NuttX footprint and still support NSH. 5083 From Alan Carvalho de Assis.. 5084 5085 * TI Calypso Phones: 5086 5087 - Basic board support for the Motorola C139 (Compal E86) phone. From 5088 Craig Comstock. 5089 5090 * Applications: 5091 5092 - Moved several useful examples from apps/examples to apps/system. 5093 This includes USB MSC, USB CDC/ACM, and USB Composite. 5094 - New addroute and delroute commands added to NSH in order to manage 5095 the network routing table. 5096 - Numerous enhancements and updates to the CC3000 example from David 5097 Sidrane. 5098 - Add a new stack monitor daemon that can be used to constantly 5099 monitor stack usage by all threads. 5100 - Numerous changes to get NSH working with no file system. Basically 5101 this suppresses I/O redirection and replaces file I/O with calls to 5102 low-level console read/write functions. Suggested by Alan Carvalho 5103 de Assis. 5104 - apps/system/nxplayer: A new, command-line media player called 5105 'nxplayer' from Ken Pettit. 5106 - apps/examples/random: Add a simple test that dumps values from 5107 /dev/random. 5108 - apps/examples/adc: Add support so that a ADC driven by software 5109 triggering can be tested. 5110 5111 * Build System: 5112 5113 - The MKDEP tools now support a new argument that identifies the 5114 object file path. 5115 5116Efforts In Progress. The following are features that are partially 5117implemented but present in this release. They are not likely to be 5118completed soon. 5119 5120 * kconfig-fronted Configuration: 5121 5122 - Conversion of old configurations to use the kconfig-frontends 5123 tool is an ongoing effort that will continue for some time. 5124 At this time, only 48% of the configurations have been converted 5125 to use the kconfig-frontends tools. 5126 5127Bugfixes (see the ChangeLog for details). Some of these are very important: 5128 5129 * Initialzation and Scheduling: 5130 5131 - IDLE thread initialization logic should not call group_setupidlefiles() 5132 if there are no file descriptors (and, hence, no file system). 5133 - Fix some cornercase error handling logic: If sched_releasetcb() is 5134 called as part of a failed pthread startup before the flags field in 5135 the TCB has been initialized, then a crash occurs. Pointed out by 5136 David Sidrane. 5137 5138 * Networking / Network Drivers: 5139 5140 - Look up of a device using subnet will fail if the packet is being 5141 sent out of our subnet (via a router). The fallback here is just to 5142 use the only device ("eth0") if the subnet lookup fails (this logic 5143 was extended to handle multiple Ethernet devices by adding a simple 5144 routing table). 5145 - Fix some backward conditional logic in send() that enabled the 5146 check if the ARP address is in the ARP table. From Max Holtzberg. 5147 - Notify the socket layer from the network monitor if a connection is 5148 lost before the monitoring callback has been registered. From Max 5149 Holtzberg. 5150 - send(): Reset the send timeout when the data is ACKed, not when the 5151 data is sent. Remove conditions on checking for timeout. From Max 5152 Holtzberg. 5153 - Correct how the TCP/IP initial minimum MSS is calculated. Max 5154 Holtzberg. 5155 - TCP state machine: Move tcp connection into SYN_RCVD state after 5156 aception instead of bypassing and moving directly into ESTABLISHED. 5157 From Max Holtzberg. 5158 - Numerous fixes to the ENCX24J600 driver from Max Holtberg. 5159 5160 * USB Drivers: 5161 5162 - Change naming of SELFPOWERED and REMOTEWAKEUP to avoid name 5163 collisions. Prepend the name of the driver (for example 5164 CDCACM_SELFPOWERED). 5165 - CDC/ACM class driver: Change the interval for the interrupt 5166 endpoint from 0xff (invalid) to 10. This is not a critical 5167 change but will avoid a complaint from the Linux driver when 5168 it overrides the 0xff value. 5169 5170 * ARM Cortex-A5: 5171 5172 - Fix an error in data cache clean and invalidate functions: Fix of 5173 addresses to cache line boundaries. 5174 5175 * Atmel AT91 SAMA5D3x Drivers: 5176 5177 - Correct some inconsistencies in the way that USB configuration 5178 settings are used. This caused compilation errors in SAMA5 OHCI 5179 when USB debug was ON but USB host tracing was off. 5180 - When 480MHz UPLL is used to drive OHCI, it should have a divider 5181 of 10. However, that does not work. A divider of 5 does. Why?. 5182 - OHCI HCD: Fix a place where DMA-related data needed to be flushed 5183 to data cache; Fix another where a virtual address was being used 5184 in a register where a physical address was required. 5185 - HSMCI Driver: TX DMA disabled. It is just not reliable. No idea 5186 why. RX DMA is still used. 5187 - STM32F103C pinmapping corrections from David Sidrane. 5188 5189 * Atmel SAMA5D3x-EK Board 5190 5191 - Increase the number of pre-allocated watchdog timers. The default 5192 number of 4 was easily being exhausted in the more complex 5193 configurations. 5194 5195 * STMicro STM32: 5196 5197 - STM32 F4 DMA definitions: Typo fixes for UART7 and UART8 DMA 5198 configs. From Mike Smith. 5199 - DMA priority configuration corrections from Mike Smith. 5200 - Changes to the stm32_dmacapable API. In order to correctly 5201 verify that a buffer can be transferred, the transfer count and 5202 the CCR value are required. Implemented stm32_dmacapable for 5203 stm32f1xx devices. Enhanced stm32_dmacapable for stm32f2xx and 5204 stm32f4xx devices to check for additional conditions that will cause 5205 DMA to fail or lose data. 5206 - STM32 F1 DMA fix from David Sidrane: The DMA_CNDTRx register 5207 cannot be modified if the DMA channel is disabled. 5208 5209 * STMicro STM32 Drivers: 5210 5211 - Fix compilation errors from bad bit definitions in ADC and PWM 5212 register. From Martin Lederhilger. 5213 - DMA-related fixes to the SPI driver from Ken Pettit. 5214 5215 * NXP LPC17xx Drivers: 5216 5217 - Remove undefined spi_select() prototype. This was causing compile 5218 time warnings. 5219 5220 * NXP LPC17xx Boards: 5221 5222 - zkit-arm-1768: MMC/SD is on SPI, not SSP0. From Rashid Fatah. 5223 5224 * C Library 5225 5226 - scanf() fixes from kfrolov: 1) sscanf() function hangs in the 5227 following example: sscanf("2", "%u,%u,%u,%u", ...), 2) sscanf() 5228 returns incorrect number of parsed numbers if some arguments 5229 can't be parsed: sscanf("=2", "%u,%u,%u,%u",...)==1 instead of 5230 0, and 3) using of char* instead of const char* in vsscanf 5231 function leads to warnings from GCC. 5232 5233 * Build System 5234 5235 - Dependency generation generation was broken for directories that 5236 keep objects in a sub-directory. The MKDEP tools now support a new 5237 argument that identifies the object file path. 5238 - tools/define.sh: 'cut' no longer works as it once did. Script 5239 adapted to observed behavior. 5240 5241 * Applications: 5242 5243 - Remove a warning from the NSH library when DHCP is not enabled. 5244 - Default NSH IP address should be 0x0a000001 (10.0.0.1), not 5245 0xa0000001 (160.0.0.1). Ditto for the gateway. 5246 - Add some missing options to the OS test Kconfig file 5247 - Fix some bad conditional compilation in the USB monitor. 5248 - Fix default I2C frequency used by the I2C tool: 400KHz instead 5249 of 4MHz. Suggested by Max Kriegleder. 5250 - Increase stack size for the system/info command. Ken Petit 5251 reports that this simple command can exceed its 768 stack size 5252 under certain conditions. The size is marginal and has been 5253 increased to 1024 by default but is also now configurable. 5254 - apps/Makefile: Needs to include external/Make.defs if we want 5255 allow external applications to participate in the NuttX 5256 configuration. Suggested by gdi@embedders.org. 5257 - apps/netutils/telnetd: Missing argument to debug statement 5258 can cause crashes in certain error conditions. From David 5259 Sidrane. 5260 - apps/examples/can: Correct an error in a debug statement. From 5261 Martin Lederhilger. 5262 5263NuttX-6.32 5264---------- 5265 5266The 99th release of NuttX, Version 6.32, was made on December 7, 2013, 5267and is available for download from the SourceForge website. Note 5268that release consists of two tarballs: nuttx-6.32.tar.gz and 5269apps-6.32.tar.gz. Both may be needed (see the top-level nuttx/README.txt 5270file for build information). 5271 5272Additional new features and extended functionality: 5273 5274 * General: 5275 5276 - Extension and standardization of stack debug logic. Now includes 5277 coloration of the IDLE and interrupt stacks as well as the heap. 5278 Suggested by David Sidrane. 5279 5280 * Audio Subsystem and Audio Drivers: 5281 5282 - I2S interface definition. Integrates with audio sub-system. 5283 - VS1053 worker thread stack size is now configurable and assigned a 5284 name via pthread_setname_np(). From Ken Pettit. 5285 5286 * Networking / Network Drivers 5287 5288 - Updates and adaptations to support for TI CC3000 wireless module 5289 from David Sidrane. These updates include multi-threading support 5290 and interface and header file changes to integrate more seamlessly 5291 with NuttX applications. 5292 5293 * File Systems: 5294 5295 - procfs: Add support for a tiny procfs file system. The initial 5296 offering is little more that a proof of concept but may be developed 5297 further in subsequent releases. 5298 - NXFFS: An initial attempt was made to integrate NXFFS with the NAND 5299 MTD driver. Changes were made to handle bad blocks. However, I 5300 later realized that NXFFS cannot handle NAND because the way that 5301 is re-writes blocks is incompatible with the NAND ECC handling. 5302 These changes were backed-out so as not to introduce turmoil, but 5303 can be re-enabled if needed via configuration option. 5304 - NXFFS: Make the start up scan of the media a configuration option. 5305 It just takes to long and is not really necessary! Those rare cases 5306 where the scan was helpful can be fixed using MDIOC_BULKERASE IOCTL 5307 command. 5308 5309 * General Drivers: 5310 5311 - I2S: A simple character driver was added to support I2S accesses. 5312 This driver in its current state is intended only to support I2C 5313 testing and would not be appropriate to used for any real driver 5314 application. 5315 5316 * MTD Drivers 5317 5318 - Add a container for an MTD device that can be used to provide a 5319 simple, lightweight interface to configuration data storage that 5320 resides on some storage media that is wrapped as an MTD device. 5321 From Ken Pettit. 5322 - New interface definition for lower half NAND drivers. 5323 - MTD Nand: Add MTD NAND driver that will support ONFI devices, 5324 non-ONFI devices (via table lookup), bad block checking, software 5325 ECC (Hamming), and will interact with the lower-half, hardware- 5326 specific, NAND driver. Based on BSD-compatible Atmel sample code. 5327 - MTD geometry structure is now packed so that it can support larger 5328 erase block sizes needed by NAND without increasing the size of 5329 the geometry structure. 5330 - SST25: Add another SST25 SerialFlash driver, sst25xx.c. This one 5331 differs from sst25.c in that it supports larger SST25 parts: In 5332 the larger parts support page write instead of byte/word writes 5333 like the smaller parts. From Ken Pettit. 5334 5335 * USB Drivers 5336 5337 - STM32 F1 USB Device: Add support for decoded USB trace strings. 5338 From David Sidrane. 5339 5340 * ARM 5341 5342 - Add more ARM9 cache management functions to flush and invalidate 5343 D-Cache for DMA support. 5344 5345 * Atmel AT91 SAMA5D3x Drivers: 5346 5347 - Many new drivers including CAN, PWM, SSC/I2S 5348 - PCK: Add support for programmable clock outputs. 5349 - NAND: Driver with hardware ECC and DMA support 5350 5351 * Atmel AT91 SAMA5D3x Boards: 5352 5353 - SAMA5D3x-EK: Add support for the apps/examples/i2schar test. 5354 - SAMA5D3x-EK: Provides board-specific memory controller initialize 5355 for NAND flash. 5356 - SAMA5D3x-EK: Add support for "auto-mounting" NAND MTD block driver 5357 or NXFFS file system. 5358 5359 * Atmel AT91 SAM3/4 Boards: 5360 5361 - Basic support for the Atmel SAM4E family. From Mitko. 5362 5363 * STMicro STM32: 5364 5365 - Added support for the STM32F429. From Ken Pettit. 5366 - Added support for GPIOK and GPIOJ. From Ken Pettit. 5367 5368 * STMicro STM32 Drivers 5369 5370 - STM32 F4 OTG FS/HS Device: OTG FS device and host drivers extended 5371 so that they can support either the OTG FS peripheral or the OTG HS 5372 peripheral (in FS mode). This was done as a quick way to get USB 5373 support on the STM32F429 which has only OTG HS. From Ken Pettit. 5374 - Added header files and driver framework for the STM32F429 LTDC 5375 framebuffer driver. From Ken Pettit. 5376 5377 * STMicro STM32 Boards: 5378 5379 - Support for the Spark board was completely by Davide Sidrane. The 5380 Spark configuration includes integrated CC3000 wireless support, FAT 5381 file system on the SerialFlash and a composite device that can be 5382 used both to export the FAT file system and to provide a serial 5383 interface. 5384 - The Mikroe-stm32f4 now uses /dev/config for configuration data 5385 storage. From Ken Pettit. 5386 - Added support for the STM32F429I-Discovery board from Ken Pettit. 5387 - Added board support for the ViewTool STM32F103/F107 board with the 5388 STM32F107VCT6 installed. 5389 5390 * NXP LPC31xx Drivers: 5391 5392 - USB ECHI HCD: Add a driver for the low-/full-/high-speed variant 5393 of the EHCI host controller. 5394 5395 * NXP LPC31xx Boards: 5396 5397 - Board-specific USB host support for the Emedded Artists EA3131 board. 5398 (Missing PCA9532 controls). 5399 - Add support for the Olimex LPC-H3131 board. Including USB host 5400 support (which does not depend on the PCA8532 interface). 5401 5402 * Kinetis KL Drivers: 5403 5404 - PWM driver for the Freescale Kinetis KL family from Alan Carvalho 5405 de Assis. 5406 5407 * Kinetis KL Boards 5408 5409 - Freedom-KL25Z: Add PWM support from Alan Carvalho de Assis. 5410 5411 * TI Stellaris LM3S 5412 5413 - Don't initialize .data in start-up logic if not running from FLASH. 5414 5415 * Applications: 5416 5417 - apps/platform: A new home for platform-specific application code. 5418 - Define a common interface that can be used to manage platform- 5419 specific configuration data. From Ken Pettit. 5420 - apps/examples/configdata: A unit test for the MTD configuration 5421 data driver from Ken Pettit. 5422 - Aapps/platform/mikroe-stm32f4: dd platform-specific storage of 5423 configuration data for the Mikroe-stm32f4. From Ken Pettit. 5424 - apps/examples/cc3000: Fine tuning of memory usage from David Sidrane. 5425 - apps/system/nxplayer: Play thread stack size is now configurable. 5426 All NxPlayer threads now have names assigned via pthread_setname_np(). 5427 From Ken Pettit. 5428 - apps/examples/i2schar: The I2S test based on the I2S character 5429 driver. 5430 - apps/examples/hidkbd/hidkbd_main.c: Now calls a function named 5431 arch_usbhost_initialize() that must be provided by the platform- 5432 specific code. 5433 - NSH: 5434 5435 - hexdump: Add skip= and count= options to the hexdump command. From Ken Pettit. 5436 - Allow USB trace without a USB console. From David Sidrane. 5437 - Mount command updates from Ken Pettit. 5438 - Add an option to the mkfatfs command to specify FAT12, FAT16, or FAT32. 5439 5440 * Tools 5441 5442 - tools/mkctags.sh: A script for creating ctags from Ken Pettit. 5443 5444Efforts In Progress. The following are features that are partially 5445implemented but present in this release. They are not likely to be 5446completed soon. 5447 5448 * kconfig-fronted Configuration: 5449 5450 - Conversion of old configurations to use the kconfig-frontends 5451 tool is an ongoing effort that will continue for some time. 5452 At this time, only 50% of the configurations have been converted 5453 to use the kconfig-frontends tools. 5454 5455Bugfixes (see the ChangeLog for details). Some of these are very important: 5456 5457 * File Systems 5458 5459 - FAT: In one error return case, the error return value was not being 5460 set, making the failure look like success. From David Sidrane. 5461 - mount: SMART FS must be included in the conditional compilation for 5462 the set of file systems that require block drivers. From Daniel 5463 Palmer. 5464 - SmartFS: Fixed a minor bug with SMART partition number reporting 5465 that would only be seen if both partition support and multi-root 5466 directory support are enabled at the same time. From Ken Pettit. 5467 - Deadlock: The inode semaphore must be re-entrant. Here is the re- 5468 entrant path that I found: (1) USB host connects to FLASH drive and 5469 creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is 5470 removed but /dev/sda is not destroyed because there is still a 5471 reference on the device because of the mount, (4) umount() is 5472 called, taking the inode semaphore, now the driver tries to destroy 5473 the block driver by calling unregister_blockdriver(). But (5) 5474 unregister_blockdriver() also takes the inode semaphore causing a 5475 deadlock if the inode semaphore is not re-entrant. 5476 - FAT: Fix a typo in the FAT16 formatting logic. Was this ever able to 5477 format a FAT16 volume? 5478 5479 * MTD Drivers 5480 5481 - MTD Partitions: Fix erase block vs page block confusion. From Ken 5482 Pettit 5483 - SST25 Serial Flash: Improved write performance by fixing a bug that 5484 prevented operation in the faster write mode. From David Sidrane. 5485 5486 * USB Drivers: 5487 5488 - USB MSC Device: pthread_join() does not work if called from a 5489 different task group than the pthread. This is correct behavior, 5490 but still a problem. The correct solution would be configure the 5491 USB MSC thread to a task, however, this workaround from David 5492 Sidrane plugs the hole for now. 5493 - USB CDC/ACM, USB MSC, and Composite Device Classes: Un-initialization 5494 logic caused re-use of a stale pointer. Changed to a two pass 5495 un-initialization for the case of the composite driver: Memory 5496 resources are not freed until the second un-initialization pass. 5497 From David Sidrane. 5498 5499 * STMicro STM32 Drivers: 5500 5501 - STM32 F1 USB Device: Fix some errors that cause crashes when the USB 5502 was disconnected. From David Sidrane. 5503 - STM32 F1 USB Device: Correct EP0 state handling logic when buffers 5504 larger than the EP0 packet size are sent. From David Sidrane. 5505 - STM32 F1 USB Device: The long outstanding bug involving the handling 5506 of OUT SETUP commands has been fixed in the STM32 F1 USB device 5507 driver by David Sidrane. 5508 - Kconfig: Add missing setup of CAN TSEG1 and TSEG2 values. From 5509 Martin Lederhilger. 5510 5511 * Tools 5512 5513 - tools/mkconfig.c: SMART FS must be included in the conditional 5514 compilation for the set of writable file systems. Noted by Daniel 5515 Palmer. 5516 5517 * Applications: 5518 5519 - apps/platform/Makefile: Was not dealing with the bin sub-directory 5520 correctly. 5521 - apps/system/composite/composite_main.c: The wrong handle was getting 5522 nullified. From David Sidrane. 5523 5524NuttX-6.33 5525---------- 5526 5527The 100th release of NuttX, Version 6.33, was made on January 30, 2014, 5528and is available for download from the SourceForge website. Note 5529that release consists of two tarballs: nuttx-6.33.tar.gz and 5530apps-6.33.tar.gz. Both may be needed (see the top-level nuttx/README.txt 5531file for build information). 5532 5533Additional new features and extended functionality: 5534 5535 * Core OS Interfaces 5536 5537 - nanosleep() added. sleep() and usleep() are no longer core OS 5538 interfaces. These have been moved into the library and re-implemented 5539 as simple wrappers around nanosleep(). 5540 5541 * File Systems 5542 5543 - procfs restructured by Ken Pettit. Added files for MTD status. 5544 - procfs extended to show uptime and task group status. 5545 - procfs now shows stack information. 5546 5547 * Networking 5548 5549 - Add support for the SO_LINGER socket option. Extended from logic 5550 provided by Jason Jiang. Enabled with CONFIG_NET_SOLINGER. 5551 - TCP write buffering support added. From Jason Jiang. 5552 - Changes from Max Holtzberg to improve how network status is 5553 reported. New controls to manage carrier detect. 5554 5555 * Graphics 5556 5557 - Massive reshuffling of files with little or no logic changes. This 5558 reshuffling was necessary to build graphics applications with the 5559 kernel builds where the graphics application lie in user space and 5560 the core graphic server likes in kernel space. Moved much logic out 5561 of nuttx/graphics to a new user library, libnx. 5562 5563 * Cortex-A5/A8/A9 5564 5565 - Existing Cortex-A5 support updated to include Cortex-A8/9. 5566 - Add the syscall.h header file needed for the Cortex-A architecture. 5567 - Start-up logic now supports execution from FLASH with .data and 5568 .bss in SDRAM. This was not possible prior to this because .bss 5569 and .data were initialized before SDRAM was configured. 5570 5571 * Allwinner A10: 5572 5573 - Basic support for the Allwinner A10 (Cortex-A8) is in place. 5574 5575 * Allwinner A10 boards 5576 5577 - Support for the pcDuino v1 board has been added. This support 5578 is not yet very mature and still lacks many drivers. It is a 5579 good starting point, however, if anyone wants to develop A10 5580 support. 5581 5582 * Atmel SAMA5D3X 5583 5584 - Start-up logic now supports execution from FLASH with .data and 5585 .bss in SDRAM. This was not possible prior to this because .bss 5586 and .data were initialized before SDRAM was configured. 5587 5588 * Atmel SAMA5D3X Boards 5589 5590 - Partial logic in place to support the OV2640 camera. Still needs 5591 quite a bit of additional logic to be useful. 5592 5593 * ARMv7-M 5594 5595 - Add support for high priority, nested interrupts. This change 5596 effects not only core ARMv-7M logic, but all ARMv7-M MCU logic: 5597 LM3S, LM4F, LPC17xx, LPC43xx, SAM3, SAM4, and STM32. See 5598 http://www.nuttx.org/doku.php?id=wiki:nxinternal:highperfints 5599 5600 * STMicro STM32 5601 5602 - Add clocking support for STM32F107 USB OTG FS (which does not yet 5603 work) 5604 - Single-wire UART support for the F1 series from Thomas Grubler. 5605 5606 * STMicro STM32 Boards 5607 5608 - The Viewtool board can now be configured to support either the 5609 STM32F103VCT6 or the STM32F107VCT6. 5610 - The Viewtool STM32F107VCT6 now supports networking with the 5611 DP83848C module installed. 5612 - Add support for Viewtool SSD1289-based LCD on the Viewtool 5613 STM32F103VCT6 board (untested) 5614 - Add support for the XPT2046 touchscreen controller on the Viewtool 5615 LCD module connected to the Viewtool STM32F103 board. 5616 - Added kernel mode build support for the STM3240G-EVAL board. Added 5617 a new kernel mode NxWM build configuration 5618 - C++ static constructor logic from the nuttx/configs/stm3240g-eval/ 5619 directory to the apps/platform/stm3240g-eval/up_cxxinitialize.c 5620 where is belongs so that it is available in user-space in the kernel 5621 mode build. 5622 - Add native Windows build support for the Olimex STM32 P107. From 5623 Max Holtzberg 5624 - Support for the STM32VL-Discovery board. Contributed by Alan 5625 Carvalho de Assis 5626 - Added a configuration for testing simple configurations on the 5627 PX4FMU v2. 5628 5629 * ZiLOG ZNEO Boards 5630 5631 - Add an NSH configuration for the Z16F2800100ZCOG ZNEO board. 5632 - Added support for the Toyaga 16Z ZNEO board. The 16Z board is 5633 based on the ZiLOG ZNEOZ16F2811AL20EG part. See 5634 https://github.com/toyaga/16z for further information 5635 - Developed a patch to work around a compiler error that is revealed 5636 when building the NSH configuration. 5637 5638 * Architecture-Independent Drivers 5639 5640 - OV2640 Camera Driver. 5641 - Support for the Sharp Memory LCD from Librae. 5642 5643 * Library 5644 5645 - Pattern matching logic extended to handle set of characters and 5646 ranges of character values. From Ken Pettit. 5647 - sleep() and usleep() moved intot the C library. These are not 5648 longer core OS interfaces; they are simple wrappers for the 5649 nanosleep(). 5650 - Add an implementation of gets_s(). 5651 - Extend fopen() to include support for C11 exclusive open ("x") 5652 open mode. 5653 - Add an implementation of stpcpy() 5654 - strtol(), strtoll, strtoul(), strtoull(), and strtod() from 5655 libc/string to libc/stdlib where they belong. 5656 5657 * Header Files 5658 5659 - Add rsize_t to include/sys/types.h 5660 - Add the C11 thread.h header file 5661 5662 * Configuration/Build System 5663 5664 - Top level Makefile now supports qconfig and/or gconfig targets that 5665 may be used for configuration. These may be used if you build 5666 kconfig-frontends with support for kconfig-qconf and/or 5667 kconfig-gconf. 5668 - Add CONFIG_DEBUG_NOOPT. Now you can independently enable/disable 5669 debug symbols and optimization 5670 - File system related header files moved to include/nuttx/fs 5671 - Video related header files moved to include/nuttx/video 5672 - Changes for native Windows build: fix creation of a .version file 5673 if one does not exist. Make sure that the APPDIR environment 5674 variable is set before configuring. From Max Holtzberg. 5675 - Board configuration sub-directory can now be specified. The default 5676 need not be used. This is only useful when CONFIG_ARCH_BOARD_CUSTOM 5677 is selected and there is no meaningful default sub-directory. 5678 - Many functions renamed to better conform with the naming standard: 5679 up_buttoninit() renamed to board_button_initialize(), up_buttons() 5680 renamed to board_buttons(), up_irqbutton() renamed to 5681 board_button_irq(), up_ledinit() renamed to board_led_initialize(), 5682 up_ledon() renamed to board_led_on(), and up_ledoff() renamed to 5683 board_led_off(). All prototypes removed from board.h header files. 5684 Now ONLY prototypes in include/nuttx/arch.h. 5685 5686 * Applications 5687 5688 - NSH: Refactor. Separate NSH command handling and command execution 5689 from NSH line parsing. 5690 - NSH: Will now support multiple commands on a command line, each 5691 separated with a semi-colon. 5692 - NSH: Add support of commands enclosed in back quotes as command 5693 arguments. 5694 - NSH: Can now handle arguments that are concatenations of constant 5695 strings, command return data, application return data, and 5696 environment variables. 5697 - NSH: Add true and false commands. 5698 - NSH: Add support for while-do-done and until-do-done loops. These 5699 only work when executing a script file because they depend on the 5700 ability to seek in the file to implement the looping behaviors. 5701 Can be conditionally compiled out to reduce footprint. 5702 - NSH: Loosen up if-then-else-fi syntax to allow a command to be on 5703 the same line as the then or else tokens like: 5704 "if true; then echo true; else echo false; fi". More like bash. 5705 - NSH: Add a break command that can be executed with a loop to 5706 terminate the loop immediately. 5707 5708 - system/inifile: A simple .INI file parser. 5709 - system/vi: Add support for a tiny, VI work-alike editor. This is 5710 a minimal full screen editor that works with a terminal emulator 5711 that using VT100 commands. 5712 5713Efforts In Progress. The following are features that are partially 5714implemented but present in this release. They are not likely to be 5715completed soon. 5716 5717 * kconfig-fronted Configuration: 5718 5719 - Conversion of old configurations to use the kconfig-frontends 5720 tool is an ongoing effort that will continue for some time. 5721 At this time, only 53% of the configurations have been converted 5722 to use the kconfig-frontends tools. 5723 5724Bugfixes (see the ChangeLog for details). Some of these are very important: 5725 5726 * Core OS 5727 5728 - Added missing sem_timedwait() system call. 5729 5730 * Networking 5731 5732 - Prevent tcp_connect callback from being double freed. From Max 5733 Holtzberg 5734 - uiplib: Support new definitions and state passing for network 5735 device status. From Maz Holtzberg. 5736 5737 * File Systems 5738 5739 - FAT: (1) A correction to FAT cluster allocation, and (2) Fix to some 5740 root directory logic that was conditionally done only for FAT 32. 5741 Apparently this needs to done for all FAT types. Both from Andrew 5742 "Tridge" Tridgell via Lorenz Meier. 5743 5744 * Binary Formats 5745 5746 - Fix a small memory leak when attempting to load a program from a file. 5747 5748 * Cortex-A8/9 5749 5750 - Fix some errors in the cache invalidation logic (only seem to matter 5751 for Cortex-A8). 5752 - Add more nop's after enabling the MMU. The cortex-a8 seems to need 5753 these 5754 5755 * Graphics 5756 5757 - Fix a typo that caused a compilation error when 5758 CONFIG_NXCONSOLE_BPP < 8. From Librae 5759 5760 * ARMv7-M 5761 5762 - Correct alignment of RAM vector table. 5763 - Interrupt handling: Do not disable and enable the IRQ on each 5764 entry, (2) this interferes with controlling the IRQ interrupt 5765 setting from interrupt handlers, and (3) up_disable_irq() does 5766 not work anyway so that this has never done anything. 5767 - Fix all implementations of up_disable_irq() for all Cortex-M3 and 5768 M4 architectures: To enable an interrupt on the Cortex-M3/4 CPU, 5769 you need to set a bit in the ISER register. To disable the 5770 interrupt, you need to set a bit in the ICER register. Existing 5771 logic was trying to disable interrupts by clearing the bit in the 5772 ISER register. That will not work; writing a '0' to the ISER 5773 register has no effect. That means that up_disable_irq() was 5774 doing nothing! It turns out that that is not really important 5775 because up_disable_irq() is not really used for that purpose. But 5776 some spurions STM32 ADC interrupts have been reported to me and this 5777 turned out to be the cause in that case. Thanks to Manuel St�hn for 5778 the tip. 5779 5780 * STMicro STM32 5781 5782 - Fix configuration and pin definitions that would prevent building 5783 USB for the connectivity and performance lines. 5784 - STM32L15xx: Fix a typo in USB pin definitions 5785 - Fix pin definition names for SPI2 MOSI and MISO. Noted by Brian Webb 5786 - Various fixes for STM32F103ZE SPI3 pin mapping definitions. From 5787 Steve Redler IV 5788 5789 * STMicro STM32 Boards 5790 5791 - Olimex STM32-P107: Failed to build if SPI3 for UEXT is not remapped. 5792 From Max Holtzberg 5793 5794 * x86 Boards 5795 5796 - Add a configuration option to select the -m32 compiler option when 5797 building for a 32-bit target on a native 64-bit compiler. So far, 5798 only used for the qemu/i486 configuration. 5799 - Patch from Matt Campbell to fix 'Error: .size expression for idle_stack 5800 does not evaluate to a constant". 5801 5802 * Library 5803 5804 - strftime(): Needs null termination on the generated string. From 5805 Max Holtzberg. 5806 - Typo in ctype.h macro name: iscntrl(), not iscontrol(). 5807 - If there are no arguments (argc == 1), then getopt() will leave the 5808 optind variable in an undefined state (2014-1-20). 5809 - ARMv7-M memcpy(): Assembler changes with the gcc-47 distribution 5810 from ARM mean that we need to be explicit about branch sizes; one 5811 or more of the wide branch opcodes results in bad table branching. 5812 From Mike Smith. 5813 5814 * Configuration/Build System 5815 5816 - Fixes for some tools/ for Windows build issues from Max Holtzberg. 5817 - Config.mk: 'cypath' must be called if we are using a Windows native 5818 toolchain with the Cygwin 'make' to convert paths to proper 5819 Windows paths. From Richard Cochran. 5820 - ARM Makefile: Dependency directory list is now computed from the 5821 VPATH. From Richard Cochran. 5822 - builtin/Makefile: Fixes for native Windows build from Max Holtzberg. 5823 - Refactor some configuration dependencies: NSH networking features 5824 should depend on netutil selections; netutil selections, in turn, 5825 should depend on networking selections. 5826 5827 * Applications 5828 5829 - NSH: Modified the df -h logic to eliminate truncating numbers in 5830 conversion (like 7900 -> 7M). From Ken Pettit. 5831 5832NuttX-7.1 5833--------- 5834 5835The 101st release of NuttX, Version 7.1, was made on March 15, 2014, 5836and is available for download from the SourceForge website. Note 5837that release consists of two tarballs: nuttx-7.1.tar.gz and 5838apps-7.1.tar.gz. Both may be needed (see the top-level nuttx/README.txt 5839file for build information). 5840 5841 The previous NuttX version was 6.33. The NuttX minor version number is 5842 incremented on each release, but the major version number is incremented 5843 only when an incompatibility with previous versions is included in the 5844 release. In this case, the legacy, manual configuration is no longer 5845 supported by the NuttX build system beginning with NuttX 7.1. Only the 5846 newer configurations generated by the kconfig-frontends tools will generate 5847 viable NuttX configurations. 5848 5849 All board configurations in the NuttX source tree have been converted to 5850 use the newer configuration, but if you have some older style configurations 5851 for you board, you will need to convert those configurations to use the 5852 kconfig-frontends tools before taking any new code from the repository. See 5853 http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some 5854 guidelines. 5855 5856Additional new features and extended functionality: 5857 5858 * Core OS: 5859 5860 - System time logic now includes logic to measure and calculate the 5861 CPU load percentage (from David Alessio). This CPU load logic 5862 extended to keep counts on each thread. The per-thread CPU is 5863 now reported in the procfs under <pid>/loadavg An asynchronous, 5864 "external" clock may be used to drive the CPU load calculations 5865 for more accurate measurements when needed. 5866 5867 * File Systems: 5868 5869 - As mentioned above, the per-thread CPU load information is now 5870 reported in the procfs under <pid>/loadavg. 5871 - Many file system interfaces have been extended to operate on the 5872 top-level NuttX pseudo filesystem. These include rmdir, mkdir, 5873 rename, and unlink. This capability can be disabled with 5874 CONFIG_DISABLE_PSEUDOFS_OPERATIONS in order to keep the footprint 5875 small. 5876 5877 * Networking: 5878 5879 - Numerous updates and improvements to the CC3000 driver from David 5880 Sidrane. 5881 5882 * Common Drivers: 5883 5884 - Defined a mouse interface that is very similar to a touchscreen 5885 interface, but allows reporting of all mouse buttons. Also, unlike 5886 touchscreen drivers, mouse drivers need to report positional data 5887 with no button is pressed so that the mouse position can drive a 5888 cursor. 5889 - Added support for a USB HID boot mouse device. Cursor support is 5890 not integrated and must be provided by the application based upon 5891 the reported mouse data. 5892 - Support added for the MIO283QT9A LCD from Toby Duckworth. 5893 5894 * Atmel SAMA4E: 5895 5896 - Added complete architecture support for the Atmel AT91 SAM4E 5897 Cortex-M4F parts. 5898 5899 * Atmel SAM4E Board Support: 5900 5901 - Add board support for the SAM4E-EK board. 5902 5903 * Atmel SAM4E Drivers: 5904 5905 - Added logic to manage the Cortex-M Cache Control block. 5906 - Developed and integrated an Ethernet MAC driver for the SAM4E. 5907 - Backported the SAMA5 SPI driver to the SAM3/4 architecture. The 5908 SAMA5 version supports both multiple SPI peripherals as needed by the 5909 SAM3A and SAM3X and also supports DMAC (but not PDC) needed by the 5910 SAM4E. 5911 5912 * Atmel SAM D20: 5913 5914 - Added basic architecture support for the Atmel AT91 SAM D20 5915 Cortex-M0+ parts. 5916 5917 * Atmel SAM D20 Board Support: 5918 5919 - Added basic support for SAM D2 Xplained Pro board. Currently, the 5920 NuttShell (NSH) works reliably over a serial port. An SPI driver 5921 has also been developed. Work with the SAM D20 has been temporarily 5922 stopped, however, in order to focus on the SAM4E-EK. 5923 5924 * TI Tiva TMC4C123G: 5925 5926 - Added architecture support for the TI Tiva TM4C123G parts. This was 5927 merged into the existing support for the LM3S and LM4F families. 5928 All directory, file, and function references changed from lm to tiva. 5929 5930 * TI Tiva TMC4C123G Board Support: 5931 5932 - Added basic board support for the TM4C123G-Launchpad. As of this 5933 release the TM4C123G-Launchpad board support is untested and likely 5934 incomplete. 5935 5936 * STMicro STM32 Boards: 5937 5938 - The Mikroe STM32F4 can now support the newer MIO283QT9A LCD. From 5939 Toby Duckworth. 5940 - Miscellaneous changes to better support FPU on STM32F429 Discovery 5941 from David Alessio. 5942 5943 * NXP LPC2378 Drivers: 5944 5945 - Incorporated I2C and SPI drivers for the LPC23xx from Lizhuoyi. 5946 5947 * QEMU i486 Drivers: 5948 5949 - New QEMU keyboard and VGA drivers from Lizhuoyi. 5950 5951 * Documentation: 5952 5953 - Added a coding standards document. See 5954 http://www.nuttx.org/doku.php?id=documentation:codingstandard 5955 5956 * Configuration/Build System: 5957 5958 - A configuration option, CONFIG_DEFAULT_SMALL, was added to select 5959 default values for configuration variables based upon whether you 5960 want a smaller footprint or more features. This is not very useful 5961 if you are modifying existing configurations because then the 5962 default values do not apply. 5963 - CONFIG_DEFAULT_SMALL has been defined on all tiny MCU configurations 5964 so that they do not grow so rapidly when new, optional features are 5965 added. 5966 - The legacy, manual configuration is no longer supported by the 5967 NuttX build system. Only the newer configurations generated by 5968 the kconfig-frontends tools will generate viable NuttX 5969 configurations. All board configurations in the NuttX source tree 5970 have been converted to use the newer configuration, but if you have 5971 some older style configurations for you board, you will need to 5972 convert those configurations to use the kconfig-frontends tools. See 5973 http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some 5974 guidelines. 5975 5976 * Applications: 5977 5978 - NSH can now use an EMACS-like command line editor. This CLE, is 5979 really more like the traditional readline than is the default, tiny 5980 the NuttX readline . 5981 - The touchscreen example can now be configured to work with either a 5982 touchscreen or a mouse device. 5983 - Several NSH commands can now be used to operate on objects in the 5984 top-level pseudo-filesystem: rmdir, mkdir, mv, and rm. This 5985 capability can be disabled with CONFIG_DISABLE_PSEUDOFS_OPERATIONS 5986 in order to keep the footprint small. 5987 - If both the CPU load feature and the procfs features are enabled, 5988 then the NSH 'ps' command will show the CPU load used by each 5989 thread. 5990 5991Bugfixes (see the ChangeLog for details). Some of these are very important: 5992 5993 * Core OS: 5994 5995 - task_terminate() always returned an error because the return value 5996 was not being set correctly (from Gosha). 5997 - nanosleep() Fix a missing call to re-enable interrupts (from Jason 5998 Jiang). 5999 6000 * File Systems: 6001 6002 - Fixed an error in the FAT logic that can cause file corruption. The 6003 error conditions are rare and only seen with very large files (from 6004 Andrew Tridgell). This replaces a previous, partial fix for the same 6005 problem. 6006 - Fixed memory leaks in the NXFFS open() and stat() implementations 6007 (from Lzyy). 6008 - The interfaces include opendir(), readdir(), et al, were modified so 6009 that errors will not be reported if you attempt to list a empty 6010 pseudo-directory. 6011 6012 * Networking: 6013 6014 - Fix one place where the connection reference count was not being 6015 decremented in the socket close() logic. This is really a cosmetic 6016 change BUT when CONFIG_DEBUG_NET is enabled, it will cause assertions. 6017 - Backed out a small part of the NuttX 6.33 write buffering changed. 6018 David G says that this causes problems in connecting to a server. 6019 - In DHCPD, there was a place where the logic was calling ntohl() 6020 inappropriately; the address was already in the correct order. How 6021 could DHCPD have worked with this bug? 6022 6023 * TI Tiva/Stellaris Drivers: 6024 6025 - Fixed cut'n'paste error that prevented UARTS2-7 from being used with 6026 the LM4F120 Launchpad. 6027 - Fixed several errors there were unmasked with UARTs > UART2 are 6028 enabled (grom Gosha). 6029 6030 * Allwinner A10 Drivers: 6031 6032 - Fixed cut'n'paste error that prevented UARTS2-7 from being used with 6033 the pcDuino. 6034 6035 * NXP LPC17xx Drivers: 6036 6037 - Fix an compilation error that crept into the LPC17xx USB host driver. 6038 6039 * STMicro STM32 Drivers: 6040 6041 - Fix cloned typo in the serial driver: FLOWCONTROL vs FLOWCONROL. 6042 - Disable SPI before changing DPI CR1 register (from David Sidrane). 6043 - stm32 TIM: Set the timer CCMR when selecting timer channel. From 6044 David Sidrane. 6045 - Fix typo in a Makefile: stm32_pwm.c not stm32_psm.c. Noted by Max 6046 Kriegleder. 6047 6048 * Library: 6049 6050 - More sscanf() bug fixes from David Sidrane. 6051 6052 * Header files: 6053 6054 - cstdbool: Ignore _Bool8 if CONFIG_C99_BOOL8=y 6055 6056 * Configuration/Build System: 6057 6058 - Several changes to restore the broken native Windows build 6059 6060 * NuttShell (NSH): 6061 6062 - Use strncpy vs strcpy in the Telnet console logic to avoid 6063 overrunning the username and password buffers (from Bertold Van den 6064 Bergh). 6065 - Add a newline after printing the file in the 'cat' command. This 6066 prevents the NSH prompt from be in the same line as the final line 6067 of the file in the case where there is no newline at the end of the 6068 file. 6069 6070NuttX-7.2 6071--------- 6072 6073The 102nd release of NuttX, Version 7.2, was made on April 29, 2014, 6074and is available for download from the SourceForge website. Note 6075that release consists of two tarballs: nuttx-7.2.tar.gz and 6076apps-7.2.tar.gz. Both may be needed (see the top-level nuttx/README.txt 6077file for build information). 6078 6079Additional new features and extended functionality: 6080 6081 * Core OS: 6082 6083 - Add support for CLOCK_REALTIME. From Macs N. 6084 6085 * Network Utilities: 6086 6087 - Add a very primitive NTP client. 6088 - DNS resolver: Long needed major clean up for coding style and 6089 unification of naming conventions (resolv vs dns). 6090 6091 * Common Drivers: 6092 6093 - Add a new MTD driver that can be used to contain another driver and 6094 force its apparent sector size to be 512 bytes. 6095 - If DCD can support queuing of stall requests, then the USB MSC stall 6096 work around delays are not necessary. 6097 - Redesign threading module used with the USB MSC driver. It was using 6098 pthreads before and these were changed to a kernel thread. The reason 6099 for this has to do with task grouping: A pthread is a memory of the 6100 group of the task that started it. A kernel thread is independent of 6101 the task that started in (other than knowing it as the parent). This 6102 allows me to remove so kludge logic to "deparent" the pthread on 6103 startup. 6104 - Update the MIO183QT-9A LCD driver to support reading from the LCD. 6105 From Toby Duckworth. 6106 - Timer "upper half" driver and l"lower half" interface definition from 6107 Bob Doiron. 6108 6109 * Atmel SAM4E/4S Board Support: 6110 6111 - All SAM4E configurations updated to run with 120MHz CPU speed and 6112 with the CMCC enabled. 6113 - Support for the SAM4S Xplained Pro board from Bob Doiron. 6114 - Add watchdog driver. From Bob Doiron. 6115 6116 * Atmel SAM4E/4S Drivers: 6117 6118 - Add a USB full speed device driver (UDP) for the SAM4E. 6119 - Add support in HSMCI and SPI drivers to invalidate cached memory if 6120 the CMCC is enabled. 6121 - Add logic to handle SPI word widths > 8 6122 - Port RTC driver from SAMA5 to SAM3/4. From Bob Doiron. 6123 - HSMCI: Extensions from Bob Doiron needed to support PDC-based HSMCI 6124 DMA transfers. Verified on the SAM4S Xplained Pro. 6125 6126 * Atmel SAMA5: 6127 6128 - Add support for the SAMA5D36 chip. 6129 - Add functions to calculate PLLACK, PCK, and MCK frequencies given 6130 the main clock frequency. 6131 - Implemented RAM functions. When booting directly into NOR flash, 6132 reconfiguring the PLL while executing out of NOR FLASH causes 6133 crashes. This was fixed by David Sidrane by implementing RAM 6134 functions. The killer code is copied and executed from ISRAM and 6135 the crash is avoided. 6136 6137 * Atmel SAMA5 Drivers: 6138 6139 - Add support for the SAMA5D3 DBGU. 6140 6141 * Atmel SAMA5 Board Support: 6142 6143 - Add a board support configuration for the Atmel SAMA5D3 Xplained 6144 board running out of SDRAM. When booting from SDRAM, start-up logic 6145 needd to query the PMC registers to determine the MCK, PCK, etc. 6146 - For all SAMA5 boards, added support for 528MHz clocking. 6147 6148 * TI Tiva/Stellaris: 6149 6150 - Modify the logic to disables the interrupts and sets the default 6151 interrupt priority so that it uses the ICTR to get the number of 6152 interrupt lines/registers. This is instead of using some fixed 6153 number of initializations based a priori knowledge of the number 6154 of interrupt lines in the MCU. 6155 6156 * STMicro STM32 6157 6158 - Add support for the STM401RE. From Frank Bennett. 6159 6160 * STMicro STM32 Boards: 6161 6162 - STM32F4Discovery: Add support to register keyboard and mouse 6163 classes if so configured. From Leo. 6164 - Add support for the Nucleo-F401RE board. From Frank Bennett. 6165 6166 * STMicro STM32 Drivers: 6167 6168 - Add STM32 Ethernet IGMP hashing support. From Manuel St�hn. 6169 - OTG FS Host: USB host tracing added by Leo. 6170 6171 * Freescale Kinetis 6172 6173 - Modify the logic to disables the interrupts and sets the default 6174 interrupt priority so that it uses the ICTR to get the number of 6175 interrupt lines/registers. This is instead of using some fixed 6176 number of initializations based a priori knowledge of the number 6177 of interrupt lines in the MCU. 6178 6179 * NXP LPC17xx 6180 6181 - Modify the logic to disables the interrupts and sets the default 6182 interrupt priority so that it uses the ICTR to get the number of 6183 interrupt lines/registers. This is instead of using some fixed 6184 number of initializations based a priori knowledge of the number 6185 of interrupt lines in the MCU. 6186 6187 * ZiLOG ZNEO Drivers 6188 6189 - Added ZNEO ESPI driver. 6190 6191 * Library: 6192 6193 - Finish incomplete support for ferror(). From Macs N. 6194 6195 * Documentation: 6196 6197 - UsbTrace.html: Add some discussion of the USB monitor. 6198 6199 * Configuration/Build System: 6200 6201 - compiler.h: Add macro UNUSED() that can be used to eliminate 6202 warnings about variables that are set to values that are not 6203 used. 6204 6205 * Debugging Support: 6206 6207 - Add a configuration option to enable dumping of the USB trace buffer 6208 on assertion. 6209 6210 * Applications: 6211 6212 - IGMP Example: Fill out Kconfig file; update makefile so that the 6213 IGMP example can be used as an NSH built-in application. From Manuel 6214 St�hn. 6215 - lcdrw Example: Fill out empty Kconfig file. 6216 - touchscreen Example: Add a configuration option to indicate if 6217 architecture-specific initialized is required, yes or no. 6218 - System usbmsc: Back out the USBMSC daemon... it is no longer needed 6219 with the recent fix to the USBMSC class driver. 6220 - NSH: malloc/free IOBUFFER for 'cat' and 'hexdump' commands instead of 6221 using the stack. From Bob Doiron. 6222 - cpuhog, serialblaster, and serialrx Examples: Stress test examples 6223 added by Bob Doiron. 6224 6225Bugfixes (see the ChangeLog for details). Some of these are very important: 6226 6227 * Core OS: 6228 6229 - errno_get_errno_ptr() and getpid(): Add some checks. If these 6230 functions are called very early in initialization before the tasking 6231 structures are initialized, they would not behave properly. 6232 6233 * Networking: 6234 6235 - IGMP-related bug fixes from Manuel St�hn. 6236 - In netdev_findbyaddr(), skip network devices that are in the "down" 6237 state. It does not make sense to consider an address match with a 6238 "down" device. From Brennan Ashton. 6239 6240 * Network Utilities: 6241 6242 - DHCPD: The correct value of the PAD option. Should be zero, not 6243 one. From Brennan Ashton. 6244 - Corrections to the NTP client from Manuel Stuehn. 6245 6246 * Common Drivers: 6247 6248 - usbhost.h: Fix some USB HID-related conditional compilation. From Leo. 6249 - USB HID mouse driver: Don't include NAKs from the device in the error 6250 count. From Leo. 6251 6252 * TI Tiva/Stellaris: 6253 6254 - Add corrected control logic for TM4C125GXL based on logic from Daniel 6255 Carvalho with modifications. The LM4F120 also works well with this 6256 change. 6257 6258 * STMicro STM32 Drivers: 6259 6260 - STM32 F2 SPI: Correct a mapping for SPI MOSI pin. From dlsitzer. 6261 - OTG FS Host: Fixes related to low-speed devices and interrupt 6262 endpoints from Leo. Necessary in order to use a USB HID mouse 6263 device. 6264 - STM32 SDIO: The dmaflight method must be conditioned on 6265 CONFIG_SDIO_PREFLIGHT. Noted by Pelle Windestam. 6266 - Sourceforge Ticket #26. up_prioritize_irq should not be called 6267 if CONFIG_ARCH_IRQPRIO is not defined. 6268 6269 * Atmel SAM3/4: 6270 6271 - Fix some backward conditional compilation in the start-up logic. 6272 - Fix initialization of the default interrupt priorities. This is 6273 a critical bug fix! 6274 - SAM4S: Fix error in macros that disable peripheral clocking. From 6275 Bob Doiron. 6276 6277 * Atmel SAMA5: 6278 6279 - Fix double mapping of SDRAM when executing out of SDRAM. In this 6280 case, the SDRAM was already mapping in arm_head.S. 6281 - In clock configuration, the BMS bit handling was fixed to match 6282 what the HW really does. From David Sidrane. 6283 - TLB Bufferable bit did not do what I thought it was going to do. 6284 I though I was selecting a write-through cache, but the result was 6285 that all caching was disabled and NOR FLASH accesses were very slow. 6286 - Move the un-definitions of __ramfuncs__ from the clock configuration 6287 .c file to the .h file. Otherwise, the attribute will be applied 6288 differently for the prototype and the function definition. 6289 Sourceforge patch 38 from Luciano Neri. 6290 6291 * Atmel SAMA5 Drivers: 6292 6293 - Fix a case in the UDPHS driver where received status was not being 6294 cleared, causing OUT SETUP commands to fail. 6295 - TWI data sending fails to increment the number of bytes transferred 6296 on first byte sent. from David Sidrane. 6297 - If running from SDRAM, then BOARD_MCK_FREQUENCY is not a constant 6298 and cannot be used in conditional compilation. All drivers fixed 6299 EXCEPT for the PWM and Timer/Counter drivers which will need some 6300 more extensive redesign. 6301 6302 * Atmel SAMA5 Boards: 6303 6304 - SAMA5D3x-EK: The red LED is controlled by PE24 which is also the 6305 camera/ISI interface reset line. So if the a camera is installed, 6306 then we must avoid controlling the red LED or we inadvertently 6307 also reset the camera module. Noted by David Sidrane. 6308 - Header files reference type xcpt_t in certain configurations and 6309 so must include nuttx/irq.h. This is Sourceforge bug 25 submitted 6310 by Luciano Neri. 6311 6312 * NXP LPC17xx Drivers 6313 6314 - arm/src/lpc17xx/Kconfig and lpc17_ethernet.c: The default interrupt 6315 priority should be default, not the highest priority (2014-4-19). 6316 6317 * ZiLOG ZNEO 6318 6319 - Fix calculation of timer reload and prescaler. The timer frequency 6320 was way too fast. 6321 6322 * Library: 6323 6324 - strncpy(): Change ordering of test and copy. Logic would have 6325 failed if n=0; one byte was always copying before testing 6326 for the end of the copy. 6327 - Fix a counting error in the return value from sscanf(). Noted by 6328 kfrolov. Also, sscanf() should return EOF if no values were 6329 converted. 6330 - Fix a logic error in ftell(). It was simply using the file offset 6331 and did not take into account data buffered in memory. From Macs N. 6332 - sccanf(): Use stroul() vs strol() with %u format otherwise, range 6333 of values is restricted because of sign bit. From kfrolov. 6334 6335 * Configuration/Build System: 6336 6337 - Fix a build error that occurs when only USB device tracing is enabled. 6338 6339 * NuttShell (NSH): 6340 6341 - Fix NuttShell version number display in the NSH welcome message. 6342 version.h was not being included. 6343 6344 * Other Applications: 6345 6346 - sysinfo: CONFIG_VERSION_BUILD is a string an needs to be 6347 printed with %s, not %d. Noted by Librae. 6348 - nxplayer: Compilation failure in one configuration reported by 6349 Manuel Stuhn. 6350 - System sdcard: Remove an STM32 dependency. From Bob Doiron. 6351 - telnetd Example: Naming is confused. In someplaces 'telnetd', 6352 and in others 'shell.' All changes to telnetd. Noted by Pelle 6353 Windestam. 6354 6355NuttX-7.3 6356--------- 6357 6358The 103rd release of NuttX, Version 7.3, was made on June 25, 2014, 6359and is available for download from the SourceForge website. Note 6360that release consists of two tarballs: nuttx-7.3.tar.gz and 6361apps-7.3.tar.gz. Both may be needed (see the top-level nuttx/README.txt 6362file for build information). 6363 6364Additional new features and extended functionality: 6365 6366 * Core OS: 6367 6368 - Dynamic loader: Framework to support Pascal P-Code as a binary 6369 format that can be exec'ed from a file system. 6370 - Dynamic Loader: Extend the binfmt interface to handle error 6371 conditions where format-specific clean-up is needed in the event 6372 of error conditions. This is needed by the P-Code binfmt. 6373 6374 * Networking 6375 6376 - IOB: Add a generic I/O buffer chain logic. This logic uses small, 6377 pre-allocated buffers that can be chained together to support 6378 transfers of any size, using fewer resources and also without 6379 committing in advance to a TCP window size. There is now only 6380 one I/O type used in the networking and it is these I/O buffer 6381 chains. 6382 - TCP Write Buffering: TCP write buffering logic converted to use 6383 I/O buffer chains. 6384 - TCP Read-Ahead Buffering: TCP read-ahead buffering logic converted 6385 to use I/O buffer chains. 6386 - Includes logic to support throttling of read-ahead buffering if 6387 the read-ahead buffering is competing with write buffering for 6388 I/O buffers. 6389 - Raw Sockets: Add support for the AF_PACKET socket family. From 6390 Daniel Lazlo Sitzer. 6391 6392 * Common Drivers: 6393 6394 - W25 Serial FLASH driver extended by Mark Whitehorn to support the 6395 8Mbit W25Q80BV part. 6396 - Add support for Fujitsu MB85RS1MT RAMTRON part. From Charles Ash. 6397 - Enhancements to the generic timer interface to support capture mode 6398 from Bob Doiron. 6399 - Add an rxflowcontrol method to the serial interface to better 6400 support RX flow control. This involves common changes in addition to minor updates to all MCU-specific serial drivers (only fully implemented for the STM32). From Jussi Kivilinna. 6401 6402 * Atmel SAM4C 6403 6404 - Add support for the SAM4CM family. From Max Neklyudov. 6405 6406 * Atmel SAM4E/4S Drivers: 6407 6408 - RTT driver from Bob Doiron. Also added high resolution RTC 6409 emulation using the RTT for the sub-second counter. 6410 6411 * Atmel SAM4E/4S Board Support: 6412 6413 - The SAM4S Xplained Pro now uses the extended timer/counter 6414 features. From Bob Doiron. 6415 - Added a touchscreen and LCD driver for the SAM4E-EK board (the LCD, 6416 however, not yet fully functional). 6417 6418 * Atmel SAMA5: 6419 6420 - Optimized, high performance, assembly language memcpy(). This is 6421 the same optimized memcpy() function that Mike Smith brought in 6422 for the ARMv7-M with minor tweaks by David Sidrane to work with 6423 the ARMv7-A. 6424 - Basic support added for the SAMA5D4 family. 6425 6426 * Atmel SAMA5 Drivers: 6427 6428 - SAMA5D4: New drivers unique to the SAMA5D4: XDMAC, SAIC, and 6429 others. 6430 6431 * Atmel SAMA5 Board Support: 6432 6433 - SAMA5D4-MB: Initial board support for the SAMA5D4-MB/EK boards. 6434 6435 * STMicro STM32 6436 6437 - Add support for the STM32152 and STM32162 Medium+ density parts 6438 (plus miscellaneous other improvements to the original STM32151 6439 logic). From Jussi Kivilinna and Sami Pelkonen. 6440 6441 * STMicro STM32 Boards: 6442 6443 - Support for the Olimex STM32 H405 board contributed by Martin 6444 Lederhilger. 6445 6446 * STMicro STM32 Drivers: 6447 6448 - Implement the rxflowcontrol method to the serial interface to better 6449 support RX flow control. From Jussi Kivilinna. 6450 6451 * NXP LPC17xx Drivers: 6452 6453 - Added support for the RTC, ADC, DAC, Timers, PWM and MCPWM 6454 drivers. From Max (himax). 6455 6456 * NXP LPC17xx Boards: 6457 6458 - Support for the RTC, ADC, DAC, Timers, PWM and MCPWM integrated 6459 in the LPCXpresso LPC1768 board support. From Max (himax). 6460 6461 * Library: 6462 6463 - Add support for seek-able streams. 6464 6465 * Configuration/Build System: 6466 6467 - Restructured network directories, header files, and naming to 6468 better modularize the networking and to better integrate the 6469 networking with the rest of NuttX. 6470 6471 * Applications: 6472 6473 - prun: An NSH built-in application that can be used to run 6474 Pascal P-Code programs either programatically or from the NSH 6475 command line. 6476 - netpkt: A "raw" socket test from Lazlo Sitzer. 6477 - hex2bin: A library and built-in task to convert from 6478 Intel HEX to binary format. It can write the binary data to a file or it can store the binary data to memory (to support, for example, a loader). 6479 6480Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): 6481 6482 * Core OS: 6483 6484 - Dynamic Loader: Fix an error in a symbol table search function. 6485 Noted by Pelle Windestam. 6486 - Dynamic Loader: Fix a critical error in exec(); argv was not 6487 being passed. 6488 - mq_notify: Test for a valid signal number was inverted; this 6489 function could not have been working correctly before??? From 6490 eero.nurkkala. 6491 - Fix typo in conditional compilation: CONFIG_CLOCK_MONOTONIC vs. 6492 CLOCK_MONOTONIC. From Manuel St�hn. 6493 6494 * Graphics 6495 6496 - Fix typos in several RGB conversion macros. 6497 6498 * Networking: 6499 6500 - Modify TCP timout handling to provent situations where connections 6501 may not be freed. From Max Holtzberg. 6502 - Improved TCP fallback allocation logic from Max Holtzberg. Also, 6503 fallback mechanism is disabled when SO_LINGER is to prevent 6504 deadlocks. 6505 - Write Buffering: Add checks from buffer allocation failures. From 6506 Max/Himax. 6507 6508 * Network Utilities: 6509 6510 - webserver: httpd_fs_open() should return OK on success and ERROR on 6511 failure, not 1 and 0. 6512 6513 * Common Drivers: 6514 6515 - Make sure that all references to up_prioritize_irq() are 6516 conditioned on CONFIG_ARCH_IRQPRIO. Problem noted by Mike Smith. 6517 - CC3000: Correct SPI mode for CC3000 is CPOL=0 CHPA=1. From Jussi 6518 Kivilinna. 6519 - CC3000: Fix a race condition in thread start-up logic. From Jussi 6520 Kivilinna. 6521 - CC3000: Additional fixes including a compilation failure if POLL is 6522 enabled. From Jussi Kivilinna. 6523 6524 * USB Drivers: 6525 6526 - CDC/ACM and PL2303 device: Reset RX head to avoid resending last 6527 serial data when USB cable disconnected/re-connected. From 6528 Lizhuoyi. 6529 6530 * TI Tiva/Stellaris Boards: 6531 6532 - The Nucleo-F401RE has no on-board crystals and, hence, needs to run 6533 with the PLL input from the on-chip HSI clock. 6534 6535 * STMicro STM32 Drivers: 6536 6537 - Serial: Handle configuration for the case of 8-bit data with 6538 parity. From Freddie Chopin. 6539 6540 * Atmel SAM3/4 Boards: 6541 6542 - There was a cloned error in all SAM3/4 board configurations (and 6543 for a few other architectures as well). Button interrupts not 6544 being disabled after being detached. As a result, unexpected 6545 interrupts could be received after the button interrupt was 6546 detached. 6547 6548 * Atmel SAMA5: 6549 6550 - Fix some critical typos in the SAMA5D3 DMA definitions. 6551 6552 * STMicro STM32 Drivers 6553 6554 - I2C: Add an alternative I2C implementation for the STM32 F103 that 6555 works around errata in that specific part. From Patrizio Simona. 6556 - RTCC: Add retry logic to RTC initialization. It sometimes takes 6557 longer for the RTC to initialize, at least as noted on an F2 part. 6558 From Daniel Lazlo Sitzer. 6559 6560 * NXP LPC17xx Drivers 6561 6562 - GPDMA: Fix an error when DMA is started: The read-modify-write 6563 fails when the DMA is started. This is because the value read is 6564 not the same as the value set (on write it is the number of 6565 transfers to do; on read it is the number of transfers completed). 6566 From Lizhuoyi. 6567 6568 * Library: 6569 6570 - snprintf(): If the size passed to snprintf() is zero, then 6571 snprintf() must write nothing, but instead return the size of the 6572 buffer needed to hold the entire string. From Sami Pelkonen. 6573 6574 * Configuration/Build System: 6575 6576 - The alternate console device CONFIG_NSH_CONDEV must not be defined 6577 unconditionally. This causes errors when using Telnet sessions. 6578 This was solved by adding CONFIG_NSH_ALTCONDEV: CONFIG_NSH_ALTCONDEV enables or disables the feature then, if 6579 enabled, CONFIG_NSH_CONDEV provides the alternative console 6580 device name. 6581 - Many files: Convert all old-style GCC variadic macros to the C99 6582 form. Recent GCC changes tightens up that behavior and can cause 6583 some problems (at least for the IAR compiler for some reason). 6584 Noted by Bob Grimes. 6585 - tools/configure.sh: In-place SED edit messes up permissions on 6586 windows. From Hannes Delago. 6587 6588 * Build Tools: 6589 6590 - tools/mkfsdata.pl: Apparently, the trailing the 0x00 in http 6591 server files is seen as a bug in javascript and images. From 6592 Max/Himax. 6593 6594 * Other Applications: 6595 6596 - I2C Tool: Fix to show the updated register address on each 6597 fetch (vs. showing the same starting address each time). From 6598 Ryan VanSickle. 6599 - CLE was not returning the terminating newline character. But 6600 reported by Max kriegleder. 6601 6602NuttX-7.4 6603--------- 6604 6605The 104th release of NuttX, Version 7.4, was made on August 15, 2014, 6606and is available for download from the SourceForge website. Note 6607that release consists of two tarballs: nuttx-7.4.tar.gz and 6608apps-7.4.tar.gz. Both may be needed (see the top-level nuttx/README.txt 6609file for build information). 6610 6611Additional new features and extended functionality: 6612 6613 * Core OS: 6614 6615 - Beginnings of a crypto/ subsystem from Max Neklyudov 6616 - Tickless operation: NuttX now supports a mode with no periodic 6617 timer interrupts. Rather, timed events are handle via an interval 6618 timer. This (1) lowers the rate of interrupt processing to timer 6619 events, (2) gives much high timing resolution, and (3) allows lower 6620 power modes of operation where the CPU is not constantly being 6621 interrupted by the timer. 6622 - Restructured the OS files under sched/ to better support the already 6623 modular nature of the RTOS. 6624 6625 * Networking 6626 6627 - Substantial directory and header file reorganization and renaming to 6628 make the NuttX networking implementation more modular. 6629 - Add network device ioctl to access PHY registers. From Daniel Lazlo 6630 Sitzer 6631 6632 * Binary Loader: 6633 6634 - Various changes associated with symbol tables from Pelle Windestam. 6635 6636 * Graphics: 6637 6638 - colorcmp(): New utility to compare two colors. 6639 - The initial background color is now configurable. Includes logic to 6640 eliminates multiple background updates to get the right color. 6641 - Minor configuration changes to handle mouse X/Y and touchscreen 6642 X/Y differently. 6643 6644 * File System/Block Drivers: 6645 6646 - SmartFS: Increase some variables from uint16_t to uint32_t to handle 6647 larger device sizes. From Ken Pettit. 6648 - Add configurable AES encryption support to the block-to-character 6649 (BCH) driver. This allows any block device to be accessed as an 6650 encrypted character device. From Max Nekludov 6651 - Add an MTD layer that will add read-ahead or write buffering to any 6652 MTD driver (incomplete). 6653 - Automounter: Add support for an auto-mounter that will automatically 6654 mount and unmount a file system a media is inserted and removed 6655 6656 * Audio/Audio Drivers 6657 6658 - WM8904 audio CODEC driver. 6659 - PCM .WAV file decoder. Fast forward implemented with sub-sampling 6660 (currently no rewind support). 6661 - Add a NULL audio device that can be used to simply unit-level testing 6662 of audio decoders. 6663 - Audio subsystem now supports interfaces for fast-forward and rewind 6664 needed by CMediaPlayer; add hooks for equalizer settings needed by 6665 the WM8904 CODEC. 6666 6667 * Other Common Drivers: 6668 6669 - MTD: Extend erase block size to 18-bits in order (decrease block 6670 size to 14-bits) to handle parts with large erase blocks. From Kosma 6671 Moczek 6672 - maxTouch: Add support for the Atmel maXTouch touchscreen controller. 6673 6674 * Host Simulation: 6675 6676 - Provides the timers needed to support the Tickless mode of operation. 6677 6678 * Atmel SAM4C: 6679 6680 - Add SAM4CM IPC register header file. From Max Neklyudov 6681 - Various fixes PMC and clock configuration for the SAM4CM port from 6682 Max Neklyudov 6683 6684 * Atmel SAM4E/4S Drivers: 6685 6686 - SAM4 AES driver. Contributed by Max Neklyudov 6687 6688 * Atmel SAMA5: 6689 6690 - Add logic to redirect all SAMA5D4 interrupts to the AIC 6691 - Add a configuration option to reserve DRAM for a framebuffer when 6692 executing out of DRAM. This optional was available before when 6693 executing out of NOR, but needs to work a little differently in 6694 this case. 6695 - Add SAMA5 slow (32.768KHz) clock support. 6696 - Add support for the ARM L2CC-PL310 L2 cache. The system runs with 6697 L2CC cache enabled but there is some issues still with the LCD DMA; 6698 I suspect that the memory timing configuration for L2CC needs to 6699 be tuned. 6700 - Provides the timers needed to support the Tickless mode of operation. 6701 6702 * Atmel SAMA5 Drivers: 6703 6704 - XDMAC-based HSCMI driver for the SAMA5D4 6705 - Adapt the SAMA5D3 LCDC driver to work with the SAMA5D4 which has 6706 no hardware cursor. 6707 - PIO: Add a new interface sam_pio_forceclk() that can be used to 6708 force PIO clocking on. I am afraid I was too conservative with 6709 PIO clocking in the initial design; this is the price. 6710 - TWI: Now supports the up_i2creset() method. 6711 - TWI: Use sam_pio_forceclk() so that we can read the current state 6712 of an open-drain output in the TWI reset logic. 6713 - SSC: SCC Frame Synch Delay and Start Delay are now configurable. 6714 - PCK: Add the slow clock and the main clocks as options for the 6715 PCK configuration. 6716 - Timer/Counter: Can now handle non-constant BOARD_MCK_FREQUENCY. Also 6717 now supports methods to attach client interrupt handlers 6718 - One shot and free-running timers. These are wrappers around the low 6719 level timer/counter logic to provide one-shot and free-running 6720 timers. These were developed to support the Tickless operation, but 6721 can be used for any purpose. 6722 6723 * Atmel SAMA5 Board Support: 6724 6725 - Add a boot loader that runs from ISRAM and loads an Intel HEX file 6726 into DRAM. 6727 - Add a configuration that will load a bootloader into AT25 Serial 6728 FLASH 6729 - SAMA5D4-EK NSH configuration supports many more features: RTC, HSCMI 6730 card detection, maXTouch touchscreen, TM7000 LCD, the command line 6731 media player (currently using the NULL audio device), automounter, 6732 and others. 6733 - SAMA5D4-EK: Add an NxWM configuration using the TM7000 LCD with 6734 the maXTouch multi-touch touchscreen. 6735 - SAMA5D4-EK NxWM: Uses new, larger icons in configuration instead of 6736 scaling. 6737 - SAMA5D4-EK NxWM: The NxPlayer and audio system are now enabled in 6738 the default configuration (but currently using the NULL audio 6739 device). The automounter is used to automatically mount media 6740 on an SD card. 6741 - SAMA5D3x-EK: Add a configuration to support the command line 6742 NxPlayer and to verify the WM8904 CODEC driver. 6743 6744 * STMicro STM32: 6745 6746 - Add support for the STM32F103RC and RD. From Kosma Moczek 6747 - Add a procfs entry to show the state of the CCM heap usage. 6748 From Pelle Winderstam 6749 6750 * STMicro STM32 Drivers: 6751 6752 - Unconfigure GPIO pins when closing a serial port to prevent back 6753 effects from back-powering on the TX pin. From Kosma Moczek 6754 6755 * NXP LPC17xx Drivers: 6756 6757 - ADC: Added burstmode ADC conversion mode, with CONFIG_ADC_BURSTMODE 6758 option in Kconfig. From Max 6759 - Ethernet: Added option to use the kernel worker thread to do most of 6760 the workload with CONFIG_NET_WORKER_THREAD option in Kconfig. From Max 6761 - Ethernet: Critical bugfix: From time to time (after some hours) the 6762 Ethernet receiver would lose one receive interrupt and the IP stack 6763 never recover because there is no receive watchdog as the transmit 6764 watchdog. From Max 6765 6766 * NXP LPC17xx Boards: 6767 6768 - mbed: Port ADC, DAC, and PWM logic from the configs/zkit-arm-1769. 6769 From Max 6770 - mbed: Eliminated a problem with PHY DP83848C : it doesn't need a 6771 specific initialization on mbed. From Max 6772 6773 * Library: 6774 6775 - Adds support for localtime. From Max Neklyudov 6776 6777 * Configuration/Build System: 6778 6779 - Make variable definitions 'static const' when possible to save RAM 6780 usage. From Kosma Moczek 6781 6782 * Applications: 6783 6784 - sysem/mdio: New PHY tool from Daniel Lazlo Sizter. 6785 - NSH: Networking logic modified to handler the case of SLIP 6786 transport. From Max Neklyudov. 6787 - NSH: Add a configuration to use a USB keyboard for the stdin 6788 device. 6789 - NSH: Software assigned MAC address is now configurable. From Lazlo. 6790 - NSH: Also add an option to let platform-specific logic select the 6791 MAC address. 6792 - NSH: There is now a configuration option that will bring up the 6793 network on an separate thread. Since the network bring-up is 6794 asynchronous, there are no serial console start-up delays due 6795 to the network negotiation time. 6796 - NxPlayer: Changes to integrate with Ken's NxWM::CMediaPlayer. 6797 - NxPlayer: Add interfaces for fast-forward and rewind needed by 6798 CMediaPlayer; add interface for equalizer settings needed by the 6799 WM8904. 6800 - NxPlayer: Supports new way of identifying the end of the audio 6801 stream (see the Audio section above). 6802 - Sudoku: Add a sudoku game. 6803 6804Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): 6805 6806 * Graphics: 6807 6808 - NxConsole: Fix scrolling for the case of the framebuffer device. In 6809 this case, the logic for clearing the vacated region at the bottom 6810 was missing so garbage would scroll up from the last, uncleared 6811 line. 6812 6813 * Networking: 6814 6815 - Important fix to the read-ahead buffer queue management: Consumed 6816 bytes were being trimmed from the head of the queue, but the queue 6817 head itself was not being updated. From Rony XLN. 6818 - Fix an error in SLIP escaping. From Max Neklyudov 6819 6820 * Network Utilities: 6821 6822 - Fix an include file ordering problem when CONFIG_NET_STATISTICS=y. 6823 - Move statistics from uip.h to new netstats.h to remove a circular 6824 inclusion problem 6825 - Various fixes for networking and tiny webserver from Max 6826 - webclient: Fix to offset calculation from Rony Xln. Prevents 0x0a 6827 at the beginning of lines. 6828 - webserver: Fix some configuration usage issues. From Max. 6829 - webserver: Missing logic to close sockets on loop termination. 6830 6831 * File System / Block Drivers: 6832 6833 - SmartFS: Fix for a bug that would show up if CONFIG_MTD_BYTE_WRITE 6834 was not selected and the SMART sector size was larger than the MTD 6835 device's block size (like it would be if using SMARTFS on larger 6836 flash devices). From Ken Pettit. 6837 6838 * Audio: 6839 6840 - Change how the end of the audio stream is detected by the leaf audio 6841 component. This used to be done by looking for the first partial 6842 buffer. That does not work with the in-place sub-sampling performed 6843 by the PCM decoder: That always reduces the size of the buffer so 6844 that all buffers only partially filled by the time they get to the 6845 leaf. Now, a flag is set in the audio buffer flags set to indicate 6846 the final buffer in the stream. 6847 6848 * Common Drivers: 6849 6850 - RAMLOG putc() method needs to set the errno and return EOF on a 6851 failure. 6852 - Add missing configuration option to select the MAX11802 touchscreen 6853 controller. From Petteri Aimonen 6854 6855 * Atmel SAMA5D3/4: 6856 6857 - Fix logic in conversion of physical and virtual DRAM addresses when 6858 running out of DRAM. This is an important bug fix for the SAMA5D3 6859 and 4 when running out of DRAM . 6860 - Critical SAMA5D3 and 4 bug fix: PIO clocking must be enabled for 6861 all input pins or else the value that is read never changes. 6862 6863 * Atmel SAMA5D3/4 Drivers: 6864 6865 - OHCI: Fix an error in a DEBUGASSERT statement. Caused an 6866 assertion to fire inappropriately when a low- or full-speed device 6867 was removed and CONFIG_DEBUG=y 6868 - OHCI: Pointers to allocated port values were not being 6869 nullified after being deallocated. This caused some assertions 6870 to fire when debug was enabled 6871 - SSC: Needs to account for data offset in audio buffer 6872 6873 * ARMv7-M: 6874 6875 - Correct the initial value of the BASEPRI register. This was 6876 apparently never being initialized! From Max 6877 6878 * STMicro STM32 Drivers: 6879 6880 - I2C: Fix missing configuration of GPIO pins in I2C driver. Fix 6881 from Alex D. 6882 - STM32 OTGFS device: Various changes to try to reduce that amount of 6883 time in interrupts handles and with interrupts disabled. From 6884 Petteri Aimonen 6885 6886 * Atmel SAM3/4 Drivers: 6887 6888 - Ethernet: Wrong bits being cleared before OR-ing in new settings. 6889 - Ethernet: Fix an error in the function that determines the number 6890 of free TX descriptors. This is an important bugfix on busy 6891 networks. 6892 - I2C: Test for read or write operation was reversed. How could 6893 this have worked before? 6894 6895 * Atmel SAM3/4 Boards: 6896 6897 - SAM4S Xplained-Pro: Correct description of LEDs and usage. From 6898 Kosma Moczek 6899 6900 * Atmel SAMA5: 6901 6902 - PIO: Fix definitions that could disable PIO interrupt support if only 6903 PIOE interrupts were enabled 6904 - PIO: Macro SAM_PION_VBASE is not define-able for the SAMA5D4 and must 6905 be replaced with a table lookup. 6906 - PIO: Fix a typo in Schmitt trigger configuration; Configure pin as a 6907 vanilla input first so that final pin configuration is more read-able 6908 (i.e., easier to debug) 6909 - PIO: Logic for Schmitt trigger selection backward 6910 - SAMA5D4: Correct system timer frequency. Input clock is MCK/2, not MCK. 6911 6912 * Atmel SAMA5 Drivers: 6913 6914 - Ethernet: Wrong bits being cleared before OR-ing in new settings. 6915 - Ethernet: Fix an error in the function that determines the number 6916 of free TX descriptors. This is an important bugfix on busy 6917 networks. 6918 - HSMCI: The 8-byte SCR transfer was failing silently with the DMA 6919 transfer, leaving the SD card in single bit mode. Fixed by adding 6920 a non-DMA read transfer mode. 6921 - HSMCI: Fix a problem on card insertion/removal callback handling. 6922 Interrupts were being disable so that the callbacks occurred with 6923 interrupts disabled. This resulted in loss of some interrupts and 6924 some not-so-good behaviors. The solution is to perform all 6925 callbacks on the work thread unconditionally 6926 6927 * Atmel SAMA5 Boards: 6928 6929 - PIO: Fix some cloned errors in SAM GPIO interrupt setup 6930 6931 * NXP LPC17xx Drivers: 6932 6933 - Ethernet: Comment out an assertion that is reported to fire 6934 inappropriately. From Max 6935 6936 * Library: 6937 6938 - stdint.h: Correct naming of [U]INT_LEASTn_{MAX|MIN} and 6939 [U]INT_FASTn{MAX|MIN}. From Kosma Moczek 6940 - unistd.h: POSIX definitions should be defined to a value. rom Kosma 6941 Moczek 6942 - Fixes associated with rint() and related interfaces in the math 6943 library. 6944 6945 * Configuration/Build System: 6946 6947 - NAME_MAX not available on SunOS; use FILENAME_MAX or MAXNAMELEN. 6948 Noted by Douglas Beattie 6949 6950 * Applications: 6951 6952 - NSH: if # appears on line, need to comment ignore additional 6953 commands on the line 6954 - NxPlayer: Check for file read errors and end-of-file with zero 6955 bytes read. Other error handling corrected as well. 6956 - NxPlayer: NxPlayer needs to set curbyte field to zero before 6957 enqueuing a buffer. Otherwise, it looks like beginning of the 6958 buffer has already been consumed. 6959 6960NuttX-7.5 6961--------- 6962 6963The 105th release of NuttX, Version 7.5, was made on September 28, 2014, 6964and is available for download from the SourceForge website. Note 6965that release consists of two tarballs: nuttx-7.5.tar.gz and 6966apps-7.5.tar.gz. Both may be needed (see the top-level nuttx/README.txt 6967file for build information). 6968 6969Additional new features and extended functionality: 6970 6971 * Core OS: 6972 6973 - Watchdog Timer Allocation: (1) If we run out of pre-allocated 6974 watchdog times, the logic will now allocate additional timers 6975 from the heap. A reserve of pre-allocated watchdog timers is 6976 maintained so that there will always be timers available for 6977 interrupt handlers. (2) Added support for statically allocated 6978 watchdog timer 6979 - Address Environment Support: (2) New OS APIs integrated into all 6980 platform-specific context switching logic (up_block_task(), 6981 up_unblock_task(), _exit(), and others). 6982 - Kernel Build Support: (1) The MPU based "kernel build" renamed to a 6983 protected build (CONFIG_BUILD_PROTECTED); added support for the a 6984 new MMU-based "kernel build" (CONFIG_BUILD_KERNEL), (2) The system 6985 call library can now be built with CONFIG_NUTTX_KERNEL. New 6986 selection: CONFIG_LIB_SYSCALL. 6987 - System Startup: Add configuration options to start the system from 6988 a program on a file system (versus an address in memory). 6989 - Startup Parameter Passing. There used to be two ways to pass 6990 parameters to new tasks, depending upon the configuration: Either 6991 (1) argv[] as created as an array with each string strdup'ed. Or 6992 (2) argv[] array and strings were created on the stack before the 6993 new task was started. Now, there is only one way, way (1). Way 6994 (2) might be slightly more compact, but this is not worth carry the 6995 complexity of two different ways of doing the same thing. 6996 - Board Initialization: Add capability to perform initial board 6997 initialization on a separate worker thread. This is needed because 6998 there are many cases where initialization logic cannot execute on 6999 the start-up/IDLE thread. That is because blocking or waiting is 7000 not permitted on the IDLE thread. 7001 7002 * Memory Management: 7003 7004 - Granule Allocator: (1) Add a new function to reserve un-allocatable 7005 regions in the granule heap. (2) Add interfaces to support 7006 un-initializing a granule allocator. 7007 - Page Allocator: Add a simple physical page allocator based on the 7008 existing NuttX granule allocator. I am not certain if the granule 7009 allocator is sufficiently deterministic for long range use, but it 7010 gets get a page allocator in place for testing very quickly. 7011 - Remove CONFIG_MM_MULTIHEAP. Non-multiheap operation is no longer 7012 supported. 7013 - sbrk(): sbrk() is now supported in the kernel build to permit 7014 dynamically sized, per-process heaps. 7015 - Per-Process Heaps: Space at the beginning of the process data space 7016 is now reserved for user heap management structures. In the kernel 7017 build mode, these heap structures are shared between the kernel and 7018 use code in order to allocate user-specific data. 7019 - User Heap Management: When a privileged thread exits, we have to 7020 use the kernel allocator to free memory; when an unprivileged thread 7021 exits, we don't have to do anything... heap memory will be cleaned 7022 up when the address environment is torn down. 7023 - Inter-Process Shared Memory Support: (1) Add implementation and 7024 documentation for shmget(), shmctl(), shmat(), and shmdt(). (2) 7025 Add system system calls to support the user call gate to the shared 7026 memory interfaces. (3) Add platform-specific interface definitions 7027 needed to support the shared memory feature. 7028 - Virtual Page Allocator: Add support for a per-process virtual page 7029 allocator. This is a new member of the task_group_s structure. The 7030 allocator must be initialized when a new user process is started and 7031 uninitialize when the process group is finally destroyed. It is 7032 used by shmat() and shmdt() to pick the virtual address onto which 7033 to map the shared physical memory. 7034 7035 * File Systems/Block Drivers/MTD: 7036 7037 - SMART FS and SMART FS procfs updates from Ken Pettit. 7038 - The MTD Read-ahead/Write buffer layer appears is now functional. 7039 7040 * Binary Formats: 7041 7042 - Add logic to initialize the per-process user heap when each user 7043 process is started. 7044 7045 * Graphics: 7046 7047 - Change all occurrences of NxConsole to NxTerm. 7048 7049 * Networking: 7050 7051 - PHY Interrupts: (1) Standardize a PHY interrupt attachment 7052 interface. (2) Add support for an ioctl that can be used to notify 7053 an application when there is a change in the network status 7054 signalled by a PHY interrupt. 7055 - Improved Send Logic: In the past, the first packet send to a new 7056 network peer would fail; there would be no entry in the ARP table 7057 for the peer and so an ARP request could replace that first packet. 7058 Now as an option if CONFIG_NET_ARP_SEND=y, all send logic will (1) 7059 check if the peer MAC address is in the ARP table and, if not, (2) 7060 send ARP requests periodically to get the mapping and (3) wait for 7061 the ARP response. Then (4) when the ARP response is received then 7062 the actual send logic will be initiated. Thus there may be a delay 7063 with the first packet sent to a new peer, but the packet should not 7064 be lost 7065 7066 * Host Simulation: 7067 7068 - Emulated SPI FLASH driver for the sim target from Ken Pettit. 7069 7070 * Intel x86: 7071 7072 - The default host is now x86_64 and the -m32 option will be 7073 automatically selected for simulation builds. 7074 7075 * Intel 8051 Family: 7076 7077 - Removed all support for the 8051 family architecture from the NuttX 7078 source tree. The obsoleted code along with the removal patch can 7079 now be found at misc/Obsoleted/. This code was removed because (1) 7080 although some functionality has been demonstrated, I am not aware of 7081 any really successful ports of NuttX to any 8051, and (2) the 8051, 7082 with its hardware stack, forces limitations and complications to the 7083 other architectures and make growth and development of NuttX more 7084 complex. 7085 7086 * ZiLOG ZNeo Boards: 7087 7088 - configs/16z: Support for this board has been removed from the NuttX 7089 source tree (but still can be found in the misc/Obsoleted 7090 directory). This port is not ready for usage but may return to the 7091 NuttX tree at some point in the future. 7092 7093 * Atmel SAM3/4 Boards: 7094 7095 - SAM4E-EK: Add (1) a fully-functional ILI9341-based LCD driver and 7096 (2) a fully-functional NxWM configuration. 7097 7098 * ARMv7-A: 7099 7100 - Address Environments: Add support for application address 7101 environments using the Cortex-A MMU. Implement standardized 7102 platform-specific interfaces of NuttX address environment 7103 support. 7104 - Cache Operations: Implement standardized, platform-specific cache 7105 operations. These are called from the ELF loader in order to flush 7106 D-cache and invalidate I-cache after an ELF module has been loaded 7107 into memory. With this change, ELF modules work correctly on the 7108 SAMA5/Cortex-A platform. 7109 - Kernel Build: (1) Add implementations of system call gate. (2) Add 7110 CRT0 start-up file that can be linked with separately built user 7111 programs. (3) Add support for delivery of use-mode signals in the 7112 kernel build. (4) Add logic to initialize the per-process user heap 7113 when each user process is started. (5) ARMv7-A exception handling 7114 needs to work a little differently if we support user mode 7115 processes. This is because R13 and R14 are paged differently 7116 between user and SVC mode. 7117 - Shared Memory Support: (1) Add logic necessary to handle remapping 7118 of shared memory on context switches. (2) Extend virtual/physical 7119 address conversions to include addresses in shared memory. (3) Add 7120 implementation of platform-specific shared memory support. 7121 7122 * Atmel SAMA5D Drivers: 7123 7124 - Implement all network ioctls, including the new ioctl to setup PHY 7125 event notifications. 7126 - In kernel build with address environment, need logic to map user 7127 virtual addresses to physical addresses, and vice versa. 7128 7129 * Atmel SAMA5D Boards: 7130 7131 - SAMA5D3 Xplained, SAMA5D3-EK, and SAMA5D4-EK: Convert existing 7132 board specific PHY interrupt interfaces to use newly defined 7133 standard interface. 7134 - SAMA5D4-EK: Add a configuration for testing the kernel build 7135 configuration. There are configurations to boot either from an SD 7136 card or from and in-memory ROMFS file system. 7137 - SAMA5D4-EK: Add documentation/support for Rev E. board. 7138 7139 * STMicro STM32 Drivers: 7140 7141 - Ethernet: Modified to support the change to the network ioctl 7142 signature changes. Also add support for new ioctl to setup PHY 7143 event notifications. 7144 7145 * STMicro STM32 Boards: 7146 7147 - STM32F4Discovery with STM32F4DIS-BB: Add a network enabled NSH 7148 configuration for the STM32F4Discovery board with the STM32F4DIS-BB 7149 base board installed. Includes support for the microSD card slot on 7150 the STM32F4DIS-BB base board. 7151 7152 * TI Tiva Drivers: 7153 7154 - Add support for the TI CC3200. From Jim Ewing. 7155 7156 * TI Tiva Boards: 7157 7158 - Add support for the TI CC3200 Launchpad. From Jim Ewing. 7159 7160 * C Library: 7161 7162 - Re-implemented poll() delay using sem_timedwait(). 7163 7164 * Configuration/Build System: 7165 7166 - Export Target: In the kernel or protected builds, (1) only the user 7167 libraries should be exported, (2) do not copy internal header files 7168 or build scripts if this is a kernel or protected build, and (3) 7169 needs to bundle up the user C startup file (crt0), not the kernel 7170 head object for the kernel and protected builds. 7171 - Add logic that will permit us to build user libraries with different 7172 CFLAGS than kernel code. This is needed because we need the 7173 -fno-common option when building ELF code to prevent SHN_COMMON 7174 relocations. 7175 7176 * Applications: 7177 7178 - NSH: Extend the NSH network initialization logic. There is now an 7179 option that will create a network monitor thread that will monitor 7180 the state of the link. When the link goes down, the code will 7181 attempt to gracefully put the Ethernet driver in a down state; When 7182 the link comes back, the code will attempt to bring the network back 7183 up. 7184 - ELF Example: The ELF test/example has been extended so the 7185 individual ELF test programs can link against the SYSCALL library 7186 (if it is available) or against the C library to eliminate or 7187 minimize the need for symbol tables. 7188 - Change all occurrences of NxConsole to NxTerm. 7189 - MTDRWB Example: Add an example to test MTD R/W buffering. 7190 - OS Test Example: Add a trivial test of sem_timedwait. 7191 7192 * Application Configuration/Build System: 7193 7194 - Import Target: (1) Add logic that will allow building applications 7195 against a NuttX export package (vs. the nuttx/ source tree). (2) 7196 Add .config file to export package. (3) Create apps/import. Create 7197 apps/import/Make.defs that does things like define CFLAGS; ELF build 7198 requires -fno-common in CFLAGS. Copy some base logic from 7199 nuttx/tools/Config.mk to apps/import/Make.defs. (4) Add 7200 apps/import/scripts/gnu-elf.ld GCC linker script for ELF import 7201 builds. 7202 - All Makefiles: (1) Add an install target to all makefiles. For 7203 the import build, the top-level Makefile now does two passes: (1) 7204 builds libapp.a, then (2) installs the programs into apps/bin. (2) 7205 Add program installation for CONFIG_BUILD_KERNEL in all Makefiles 7206 that build a main(). (3) For kernel build, the object file 7207 containing main cannot go into library because of name collisions. 7208 The object file must be handled as a special case in every Makefile. 7209 - All Built-In Programs: With kernel build (CONFIG_BUILD_KERNEL), 7210 entry point to all tasks is main(), not some xyz_main(). 7211 - NSH: Several commands must be disabled in the kernel build because 7212 they depend on interfaces that are not available outside of the 7213 kernel: dd, df, losetup, mkfatfs, mkdr, and ps. 7214 - apps/tools/: (1) Add mkimport.sh to expload an NuttX import package 7215 and install in apps/import. (2) Add mkromfsimg.sh script to create 7216 a BOOT ROMFS filesystem image. 7217 - ELF and NxFLAT Examples: Do not build test cases that use 7218 task_create() if there is an address environment. 7219 7220 * Tools: 7221 7222 - refresh.sh: Add a tool to make refreshing configurations easier 7223 when you want to do a lot of them. 7224 - mksyscall.c: Build syscalls that do not need header files. 7225 - mkexport.sh: Add .config file to export package. 7226 - See above for new apps/tools scripts. 7227 7228Efforts In Progress. The following are features that are partially 7229implemented but present in this release. They are not likely to be 7230completed soon. 7231 7232 * Processes. Much of the work in this release is focused on the 7233 realization of Unix-style user processes in NuttX. There is more to 7234 be done, however. The full roadmap and status is available at: 7235 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 7236 7237 * XMega: There are some fragments in place for an XMega port. That 7238 port has not really started, however. 7239 7240 * Galileo: Similarly, there are fragments in place for an Intel Galileo 7241 port. The port not been started in earnest either. 7242 7243Bugfixes. Only the most critical bugfixes are listed here (see the ChangeLog for the complete list of bugfixes and for additional, more detailed bugfix information): 7244 7245 * Core OS: 7246 7247 - Kernel build fixes: (1) IDLE TCB setup needs to indicate that the 7248 IDLE thread is a privileged, kernel thread. (2) Don't build 7249 task_create() or task_spawn() interfaces if there is an address 7250 environment. (3) posix_spawn() kernel proxy thread should be a 7251 kernel thread, not a user task. 7252 - Several pthread interfaces: Add const storage class to phthread 7253 parameters. From Freddie Chopin. 7254 - sched/clock: Remove vestiges of g_tickbias; need, instead, to apply 7255 time bias to g_basetime in order to provide the correct system time. 7256 - System Calls: (1) Several typos fixed; corrected integration of 7257 exevc(), execvl(), posix_spawn, and posix_spawnp system calls. (2) 7258 If we are configured to use a kernel stack while in SYSCALL handling, 7259 then we need to switch back to the user stack to deliver a signal. 7260 7261 * File Systems/Block Drivers/MTD: 7262 7263 - procfs: Fix some procfs breakage introduced by reorganizing some 7264 non-reorganizable data structures. From Ken Pettit. 7265 - AT45: In at45db_bwrite , the buffer is not increased when writing 7266 more than 1 page. Sourceforge bug #34. 7267 7268 * Binary Formats: 7269 7270 - ELF relocations. Some relocation types do not have a named symbol 7271 associated with them. The design did not account for that case. 7272 - ELF Loader: Critical bugfix.. BSS was not being cleared. 7273 7274 * Memory Management: 7275 7276 - Granule allocator initialization uses wrong allocator to setting 7277 aside kernel memory. 7278 - Add a flag to group structure: If the group is created by a kernel 7279 thread, then all resources in the group must be privileged. 7280 7281 * Cryptogrphic Support: 7282 7283 - crypto/cryptodev.c: Path segments reversed in include file path. Noted by Brennan Ashton. 7284 7285 * Common Drivers: 7286 7287 - Common CAN upper-half: In can_txdone, waiters on the semaphore 7288 should be informed regardless of the return value of can_xmit. First 7289 it returns -EIO if there are no new packets, and second the 7290 information of the waiters is about the last transferred packet. 7291 From Daniel Lazlo Sitzer. 7292 7293 * ARM: 7294 7295 - System Calls: Fix a typo in system call when fetching parameter from 7296 the stack: regs[REG_PC]+4 is the address, not regs[REG_PC+4]. 7297 7298 * STMicro STM32 Drivers: 7299 7300 - STM32 F401 UART: Correct support for USART6 on this chip. From 7301 Freddie Chopin. 7302 - STM32 FLASH fixes: use size_t instead of uint16_t, make interface 7303 more generic. From Freddie Chopin. 7304 - Fix for UART7 and UART8 on STM32 clock enable from Aton. 7305 - CAN: At the end of the interrupt handler, the interrupts were being 7306 disabled, if all packets have been transferred when the interrupt 7307 handler was invoked. This is problematic, because the interrupt 7308 handler calls can_txdone of the upper half which can enqueue new 7309 packets to send. Removed the block altogether, because can_txdone 7310 calls can_xmit which disables interrupts if there are no new packets 7311 to send. From Daniel Lazlo Sitzer. 7312 - Additional STM32 CAN correction suggested by Max Holtzberg. 7313 7314 * STMicro ST32 Boards: 7315 7316 - configs/mikroe-stm32f4: Fix a few compile bugs and minor corrections 7317 to the mikroe-stm32f4 configuration source. From Ken Pettit. 7318 7319 * ARM9/ARMv7-A: 7320 7321 - System Calls: Fix ARM7/9 and Cortex-A SYSCALLs: For threads in SVC 7322 mode, the SVC instructions clobbers R14. This must be taken account 7323 in the inline assembly. 7324 - Task Setup: All tasks, even user mode tasks, must start in 7325 supervisor mode until they get past the start-up trampoline. 7326 - ARMv7-A: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. 7327 It changed CPSR while in kernel. That will crash if the new CPSR is 7328 user mode while executing in kernel space. Fixed by adding a 7329 SYS_context_restore system call. There is an alternative, simpler 7330 modification to up_fullcontextrestore() that could have been done: 7331 It might have been possible to use the SPSR instead of the CPRSR and 7332 then do an exception return from up_fullcontextrestore(). That 7333 would be more efficient, but I never tried it. 7334 7335 * Atmel SAM3/4 Boards: 7336 7337 - SAM3X/Arduino Due: Fix typo in sam3x_periphclks.h; add SCLK 7338 definitions to board.h header file. From Fabien Comte. 7339 - SAM3 RTT: Only SAM4 family has RTTDIS bit in the MR register. 7340 SourceForge bug #33 from Fabien Comte. 7341 7342 * C Library: 7343 7344 - sscanf(): NuttX libc tried to guess how many characters to parse, 7345 extracted them into a buffer, then ran strtol() on that buffer. 7346 That guess was often wrong. A better approach would be to call 7347 strtol() directly on the input data, using the endptr return value 7348 to determine how many characters to skip after parsing. From Kosma 7349 Moczek. 7350 - Corrected atan2 implementations from Denis Arnst. 7351 - Change to lib_dtoa() to fix precision error from trailing zeroes. 7352 From Bob Doiron. 7353 7354 * Applications: 7355 7356 - Fix NSH PS command: If there are no arguments, it could print 7357 garbage for argument list. 7358 7359 * Configuration/Build System: 7360 7361 - Null Example: Need to include config.h it order know if this is or 7362 is not a kernel build. This problem still exists in several other 7363 file that may need to define main(). 7364 7365NuttX-7.6 7366--------- 7367 7368The 106th release of NuttX, Version 7.6, was made on November 26, 2014, 7369and is available for download from the SourceForge website. Note 7370that release consists of two tarballs: nuttx-7.6.tar.gz and 7371apps-7.6.tar.gz. Both may be needed (see the top-level nuttx/README.txt 7372file for build information). 7373 7374Additional new features and extended functionality: 7375 7376 * Core OS: 7377 7378 - Moved name semaphore and message queue support out of the OS and 7379 into the VFS. These improves the architecture by unifying the 7380 management of named resources, removes redundant resource management 7381 logic, and makes named semaphores and message queues visible in the 7382 file system. By default, these are visible at /var/lock and 7383 /var/mqueue. 7384 - Add SIGPOLL for use as part of the AIO implementation. 7385 - Remove CONFIG_MAX_TASK_ARGS configuration. There is now no 7386 predetermined limit on the number of arguments that may be passed 7387 to a new task on start-up. 7388 7389 * Work queues: 7390 7391 - Add support for priority inheritance on the low priority worker 7392 queue. That is, if a higher priority thread has scheduled work, the 7393 priority of the low priority worker thread(s) will be boost to the 7394 priority of the queuing thread. At work is performed at at least 7395 thread priority of the scheduling thread. If there are multiple 7396 worker threads, then all threads get reprioritized. Currently 7397 only implemented for AIO. 7398 - Add support for multiple low-priority work queue threads. This 7399 allows individual worker threads to block indefinitely for I/O as 7400 necessary without halting the entire work queue. 7401 7402 * VFS/General Drivers: 7403 7404 - Implement create() (as a macro). 7405 - Add pread() and pwrite(). Also added pread() and pwrite() 7406 system calls. 7407 - AIO: Add aio_read(), aio_write(), aio_return(), aio_error(), 7408 aio_suspend(), aio_canel(), lio_listio(), and aio_fsync(). This 7409 logic minimizes the creation of new threads by using the new 7410 features also added to the low priority work queue with this 7411 release. It uses the new low priority worker thread interface 7412 to adjust the priority of the worker thread according to the 7413 priority of the AIO client thread 7414 - Implement standard syslogmask() to control logging (also removing 7415 the non-standard syslog_enable()). 7416 7417 * File Systems/Block Drivers/MTD: 7418 7419 - Extend MTD support to the M25P16. From S�bastien Lorquet. 7420 7421 * Drivers: 7422 7423 - BCH (Block-to-Character): Add support for seeking in BCH. From 7424 S�bastien Lorquet. 7425 7426 * Graphics Support/Graphics-Related Drivers: 7427 7428 - Add support for a generic ILI9341 LCD driver. From Marco Krahl. 7429 - Add ANSI/VT100 foreground and background color commands. 7430 - Add driver for ST7565 LCD that works with NHD-C12864KGZ display. From Pierre-noel Bouteville. 7431 7432 * Networking: 7433 7434 - Verify that multiple networks can be supported. 7435 - Add support for the case where there are multiple networks: One 7436 being Ethernet and the other not (SLIP, PPP, ...). The primary 7437 difference from the standpoint of the stack is that (1) ARP may or 7438 may not be necessary, (2) the size of the link layer header will 7439 vary, and (3) different MTUs and TCP receive windows may be used 7440 with each link. Suggested by Brennan Ashton. 7441 - Extensions to UDP and TCP connection structures for the case of 7442 multiple networks. In this case, assigned port numbers only have to 7443 be unique with respect to the IP address. So, for example, you 7444 could have multiple port 80's, one on each network. 7445 7446 * Host Simulation: 7447 7448 - Removed the old, strange up_stdio.c and implemented a simulated UART 7449 driver to provide the console input. The new logic starts a 7450 separate, Linux domain pthread to read the console input in raw mode 7451 and provides the incoming data to NuttX via standard NuttX domain 7452 IPCs. 7453 - Add support for 64-bit longjmp/setjmp in simulator platform. This 7454 will permit operation of the simulation natively on a 64-bit 7455 platform. 7456 7457 * ARMv7-M: 7458 7459 - Add ARMv7-M CMSIS ITM header file and library. From Pierre-noel 7460 Bouteville. 7461 - Add ARMv7-M CMSIS DWT and TPI header files. From Pierre-noel 7462 Bouteville. 7463 - Add ARMv7-M support to use ITM for SYSLOG debug output. Includes 7464 logic from Pierre-noel Bouteville. 7465 7466 * Atmel SAM3/4 Drivers: 7467 7468 - Add support for SAM3/4 basic serial TERMIOS and flow control. 7469 There are issues with IFLOW control: PDC or DMAC support is 7470 required. 7471 7472 * Atmel SAM3/4 Boards: 7473 7474 - SAM4E-EK: Add support for PHY interrupt. 7475 7476 * Atmel SAMA5D Boards: 7477 7478 - SAMA5D3-Xplained: Add a configuration that provides a simple test 7479 for the EMAC and GMAC on the SAMA5D3 working together. 7480 - SAMA5D4-EK: Add a configuration that provides a simple test for the 7481 EMAC0 and EMAC1 on the SAMA5D4 working together. 7482 7483 * Freescale KL: 7484 7485 - Add an I2C header file for the Freescale KL family. From Alan 7486 Carvalho de Assis. 7487 7488 * NXP LPC32xx: 7489 7490 - Add support for tickless operation using the NXP LPC43xx. From 7491 Brandon Warhurst. 7492 7493 * SiLabs EFM32: 7494 7495 - Add a basic port for the SiLabs EFM32 family. Includes many files 7496 contributed by Pierre-noel Bouteville . 7497 7498 * SiLabs EFM32 Boards: 7499 7500 - Add board support for the EFM32 Gecko Starter Kit. 7501 - Add board support for the Olimex EFM32G8809128 STK. NOTE: I am 7502 unable to test this configuration due to tool-related issues. 7503 - Add board support for the SiLbas EFM32GG Giant Gecko Starter kit. 7504 7505 * STMicro STM32: 7506 7507 - Add support for the STM32 F411RE from Serg Podtynnyi. 7508 - Add support for the STM32F103RG. From Murilo Ponte. 7509 7510 * STMicro STM32 Drivers: 7511 7512 - STM32 F4: Add logic that implement true high speed support for the 7513 STM32 OTGHS peripheral and concurrent support for both LS and HS 7514 OTG. New OTGHS drivers provided for both device and host. From 7515 Brennan Ashton. 7516 7517 * STMicro STM32 Boards: 7518 7519 - STM32 Nucleo-F411RE: Extend this board configuration to also support 7520 the Nucleo-F411RE. From Serg Podtynnyi. 7521 - Add support for the STM32F429i Discovery's LCD (SPI based). From 7522 Marco Krahl. 7523 - configs/stm32f100rc_generic: Removed this generic board configuration. 7524 I have decided to stop support of generic board configurations. Generic 7525 board configurations do not provide support for any specific hardware 7526 but can be useful only if there are not other examples for the setup 7527 for a particular architecture. Not the case here. 7528 7529 * C Library: 7530 7531 - Add a mostly bogus wchar.h header file. This file is mostly bogus 7532 because none of the wide character operations are currently 7533 supported in the Nuttx C library. The file does provide the wchar_t 7534 types needed by some software, however. 7535 - Add isatty() function. From Alan Carvalho de Assis. 7536 - Add mktemp(), mkstemp(), tmpnam() and tempnam(). 7537 7538 * Configuration/Build System: 7539 7540 - Add a PRELINK macro to Config.mk. From Kriegleder. 7541 - compiler.h: Defines inline functions as not instrumented - this is 7542 relevant for anyone using instrumentation. From Lorenz Meier. 7543 7544 * Applications: 7545 7546 - apps/interpreter/bas: Added in the Michael Haardt's BAS 2.4 adapted 7547 for use by NuttX by Alan Carvalho de Assis. Includes support for 7548 VT100 terminals and color commands. 7549 - Examples: Added bastest/ which holds a special version of Michael 7550 Haardt's BAS 2.4 test files adapted for use by NuttX on a ROMFS file 7551 system. 7552 - Examples: Add a simple UDP relay bridge for testing configurations 7553 with multiple networks. Includes a host-side test driver for 7554 testing the bridge. 7555 - Netutils: Add implementation of timeouts for the netutils webclient. 7556 From Brennan Ashton 7557 - NSH: Add support for a custom NSH ROMFS startup image header file 7558 location. From Martin Lederhilger. 7559 - OS test: Add a simple test of named semaphores. 7560 - OS test: Add AIO test case in OS test. 7561 7562Efforts In Progress. The following are features that are partially 7563implemented but present in this release. They are not likely to be 7564completed soon. 7565 7566 * Processes. Much of the work in this release is focused on the 7567 realization of Unix-style user processes in NuttX. There is more to 7568 be done, however. The full roadmap and status is available at: 7569 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 7570 7571 * XMega: There are some fragments in place for an XMega port. That 7572 port has not really started, however. 7573 7574 * Galileo: Similarly, there are fragments in place for an Intel Galileo 7575 port. The port not been started in earnest either. 7576 7577Bugfixes. Only the most critical bugfixes are listed here (see the 7578ChangeLog for the complete list of bugfixes and for additional, more 7579detailed bugfix information): 7580 7581I ran cppcheck against the entire code base and correct many latent bugs 7582including things as serious as memory leaks, two locations where interrupts 7583were be disabled but never re-enabled, and errors in the Tickless mode of 7584operation. My thanks to the developers of cppcheck! I am impressed! 7585 7586 * Core OS: 7587 7588 - vfork(): Now that arguments are kept on the stack, the way that 7589 arguments are passed from parent to child in vfork() must change. 7590 This bug has always been present, but was not visible with the 7591 old strdup() way of passing arguments. 7592 - vfork() problem: If we get to vfork() via system call, then we 7593 need to clone some system call information so that the return form 7594 the cloned system call works correctly. 7595 - Fixes to tickless operation code, especially in alarm mode. From 7596 Brandon Warhurst. 7597 - Fix an important bug in the watchdog timer creation logic. 7598 - Calling mq_timedreceived() with immediate timeout was getting stuck 7599 and not timing out. Immediate timeout is achieved by setting absolute 7600 timeout value to past time, for example abstime={ .tv_sec=0, 7601 .tv_nsec=0 }. However absolute time was converted to relative time 7602 using unsigned integer arithmetic and resulted large ticks count by 7603 clock_abstime2ticks, instead of expected negative ticks value. 7604 Change corrects clock_abstime2ticks() to return negative ticks, if 7605 absolute time is in the past. From Jussi Kivilinna. 7606 7607 * Memory Management: 7608 7609 - Fix a place in the memory manager where it explicitly assumed that 7610 the size of a pointer is 4 bytes. That assumption was OK if the 7611 actual size is smaller but made the heap unstable when used with 7612 the x86_64 host simulation. 7613 - Granule Allocator: If the INTR granule allocator mode is enabled, 7614 there is no semaphore to destroy. From Lorenz Meier. 7615 7616 * Networking: 7617 7618 - Network routing: I don't think that the net_route() function has 7619 ever worked correctly. The source IP was updated in the match 7620 struct instead of the route IP. From Brennan Ashton. 7621 - Move and rename IP header flag definitions. The problem fixed here 7622 is that there IP header flag definitions were not available when TCP 7623 was disabled. The IP flags are used in ICMP and IGMP. 7624 - Network routing: Refuse to perform routing table lookups for the 7625 Broadcast IP address. From Brennan Ashton. 7626 - Network routing: Add logic to netdev_findbyaddr() to return the 7627 correct network device for the case where a broadcast 7628 address is used. This change caused trivial ripples through other 7629 files because additional parameters are required for 7630 netdev_findbyaddr() when CONFIG_NET_MULTINIC. 7631 7632 * File Systems/Block Drivers/MTD: 7633 7634 - NXFFS Dump: Fix problems with redefinitions of fdbg macro. With the 7635 fix to the syslog prototype, a LOG priority must now be the first 7636 parameter. Fixed by replacing all occurrences of fdbg with 7637 syslog(LOG_DEBUG, and eliminating the macro redefinitions. Noted 7638 by Sebastien Lorquet. 7639 - poll() was not waking up from signals (for example mq_notify() 7640 events). From Jussi Kivilinna. 7641 - poll(): Add proper handling for sem_timedwait errnos. From Jussi 7642 Kivilinna. 7643 - include/nuttx/fs/fs.h: Fix typo in conditional compilation. From 7644 Alan Carvalho de Assis. 7645 7646 * Graphics/Graphic-Related Drivers: 7647 7648 - Remove warnings when CONFIG_NXTK_BORDERWIDTH is set to zero. From 7649 Pierre-Noel Bouteville. 7650 7651 * Common Drivers: 7652 7653 - Make standard syslog and vsyslog POSIX compliant (also modify 7654 non-standard syslog functions for compatibility). 7655 - R/W buffering: Fix typo that can cause compilation error. 7656 7657 * Atmel SAM3/4: 7658 7659 - SAM4S: Add missing SPI0 clock configuration macro for the SAM4S. From spasbyspas. 7660 7661 * Atmel SAM3/4 Drivers: 7662 7663 - SAM4E-EK: Fix an error in a USART1 pin number. 7664 7665 * Atmel SAMA5D3/4 Drivers: 7666 7667 - SAMA5DF4: Fix several typos that will prevented EMAC1 from 7668 initializing properly. 7669 7670 * NXP LPC43xx: 7671 7672 - Fixes to allow compile of lpc43_gpioint.c. From Brandon Warhurst. 7673 7674 * STMicro STM32: 7675 7676 - Add missing ADC pinmap definitions for the STM32 F103R from Martin 7677 Lederhilger. 7678 7679 * STMicro STM32 Drivers: 7680 7681 - STM32 EXTI: Correct STM32 RTC EXTI bit definition. From Lazlo. 7682 - STM32 IWDG, WWDG, DBGMCU: Fix watchdog stop bit usage. From Lazlo. 7683 - STM32 OTGFS: Correct a typo in the STM32 OTGFS register bit definitions. 7684 7685 * ARM: 7686 7687 - ARM up_internal.h: Add protection from C++ name mangling in the 7688 ARM up_internal.h. From Lorenz Meier. 7689 7690 * MicroChip PIC32MX: 7691 7692 - PIC32MX7: DEVCFG0 bit 2 must be set. Writing bit 2 as zero can 7693 brick the CPU on some versions. From Cris Kvist. 7694 7695 * C Library: 7696 7697 - The implementation of access() as vararg macro has the issue that 7698 any function call with the same name (even in a C++ class) will 7699 match with it and result in a compile error. Replaced with a small 7700 function. This resolves the compile issue, and shouldn�t have 7701 negative side effects for users of the function. From Lorenz Meier. 7702 - The definition of strncpy() is that empty space should be zero- 7703 filled, the change adds the zero filling (See the POSIX spec here: 7704 http://pubs.opengroup.org/onlinepubs/7908799/xsh/strncpy.html). From 7705 Lorenz Meier. 7706 - limits.h: Remove the definition of INT_FAST32_MIN which is already 7707 defined in stdint.h (the correct location). From Lorenz Meier. 7708 7709 * Applications: 7710 7711 - apps/: Correct everything under apps to use the corrected syslog 7712 interfaces. Remove any non-portable uses of syslog. 7713 - NSH: Fix ls -l output for regular files. 7714 - NSH: Fix reversed in/out file closing in DD command when an error 7715 occurs. From Ken Pettit. 7716 - NSH: Add logic to restart the console wait if an error occurs 7717 while reading from the console. In USB console startup, the logic 7718 must be able to open the USB serial and receive 3 newlines. 7719 However, it the USB driver is disconnected or otherwise fails before 7720 the 3 newlines are received, the receive loop becomes a killer, 7721 infinite loop, CPU hog. Noted by spasbyspas. 7722 - Netutils: Fix memcpy of host address in netlib_gethostaddr(). From 7723 Brennan Ashton. 7724 - Netutils: If you make a DNS request before the DNS address it would 7725 cause an assertion. The state of the IP setting is not something the 7726 application should be aware of, it should only be concerned with 7727 whether or not the name was resolved. From Brennan Ashton. 7728 - Netutils: Fix md5 hashing when digest[$i] islower that 16. From 7729 Sergey. 7730 - Stack Monitor: Fix compile problems introduced when the syslog() 7731 prototype changed; Also update Makefile for kernel build From 7732 Radoslaw Adamczyk. 7733 - Examples: Update NxTerm makefile for kernel-build issues. From 7734 Radoslaw Adamczyk. 7735 - Examples: Fixes to keypadtest from Pierre-Noel Bouteville. 7736 - Examples: These examples all set the IP address of eth1 but the 7737 netmask and gateway of eth0 if DHCP is enabled: discover, tcpecho, 7738 webserver, xmlrpc. That can't be right. 7739 7740NuttX-7.7 7741--------- 7742 7743The 107th release of NuttX, Version 7.7, was made on January 26, 2015, 7744and is available for download from the SourceForge website. Note 7745that release consists of two tarballs: nuttx-7.7.tar.gz and 7746apps-7.7.tar.gz. Both may be needed (see the top-level nuttx/README.txt 7747file for build information). 7748 7749Additional new features and extended functionality: 7750 7751 * Core OS: 7752 7753 - Task exit handling: Add logic to clean up after task_delete() or 7754 pthread_cancel() if the task happens to be waiting on a semaphore 7755 when was is cancelled. 7756 - Stack coloration: Removed CONFIG_DEBUG_STACK and replaced it with 7757 CONFIG_STACK_COLORATION that does the same thing but without enabling 7758 debug. From David Sidrane. 7759 7760 * Common Drivers: 7761 7762 - Discrete joystick driver: Added an interface definition and upper 7763 half driver for a discrete joystick device (where X/Y changes are 7764 indicated with button presses). 7765 - Analog joystick driver: Added an interface definition and upper 7766 half driver for a analog joystick device (where X/Y positions are 7767 sampled, numeric values). 7768 - Add driver support for the ADXL345 accelerometer. From Alan 7769 Carvalho de Assis 7770 - Generic serial driver: Add watermark levels to the serial RX flow 7771 control logic. Modify the rxflowcontrol method to accept the number 7772 of bytes in the buffer and a boolean indication of which watermark 7773 was crossed. 7774 7775 * File Systems/Block Drivers/MTD: 7776 7777 - Add procfs write support. From Ken Petit. 7778 - Implemented wear-leveling in the SmartFS. From Ken Pettit. 7779 - MMC/SD Interface: MMCSD SDIO: Add support for a new 7780 SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait 7781 loop to poll the card R1 status to determine when the card was 7782 ready for the next transfer. That busy-wait can be quite long -- 7783 up to hundreds of milliseconds. An alternative is to look the SD D0 7784 pin which will change state when the card is no longer busy. This 7785 change avoids the busy-wait poll by reconfiguring the SD D0 pin as a 7786 GPIO interrupt, then waiting for the card to become ready without 7787 taking up CPU cycles. From David Sidrane. 7788 7789 * Drivers: 7790 7791 - Add support for a generic EEPROM driver that accesses EEPROM as a 7792 character driver (vs. an MTD driver). From S�bastien Lorquet. 7793 7794 * Graphics Support: 7795 7796 - Many new fonts converted for use with NuttX and added by 7797 Pierre-noel Bouteville 7798 7799 * Networking: 7800 7801 - IPv4 support is now conditioned on CONFIG_NET_IPv4. 7802 - Implemented and verified IPv6 support conditioned on 7803 CONFIG_NET_IPv6. Either IPv4 or IPv4 or both may be selected. 7804 Sockets, of course, must be bound to one or the other. Added support 7805 for IPv6 ioctls to manipulate IP addresses. 7806 - Integrated support for ICMPv6 and the ICMPv6 Neighbor Discovery 7807 Protocol and ICMPv6 ECHO request/reply needed to support ping logic. 7808 - All Ethernet drivers: Modified to support. Most, however, are 7809 still missing address filtering logic required for ICMPv6 Neighbor 7810 Discovery Protocol. See 7811 http://www.nuttx.org/doku.php?id=wiki:howtos:ipv6#ethernet_driver_requirements 7812 - Also added missing raw/packet socket support to all Ethernet drivers. 7813 7814 * Host Simulation: 7815 7816 - Add a configuration build and test the Traveler first person game 7817 using the simulator. 7818 - Add an X11 mouse-based simulation of an analog joystick device 7819 7820 * Atmel SAMA5D Boards: 7821 7822 - Add analog Joystick shield support for the SAMA5D3 Xplained board. 7823 7824 * Freescale KL Drivers: 7825 7826 - Add GPIO interrupt capability for the KL architecture. From Alan 7827 Carvalho de Assis 7828 7829 * Freescale KL Boards: 7830 7831 - Freedom-KL25Z: Add board support for the ADXL345 accelerometer. From 7832 Alan Carvalho de Assis 7833 - Freedom-KL25Z: Update the Freedom KL25Z board CC3000 support to use 7834 the current CC300 interfaces. From Alan Carvalho de Assis 7835 7836 * NXP LPC43xx Boards: 7837 7838 - A port of NuttX to the LPC4357-EVB from Toby Duckworth. This port 7839 is a leverage of the LPC3330-Xplorer port and still have a some 7840 misinformation from that port that needs to be updated for the 7841 LPC4357-EVB. 7842 7843 * SiLabs EFM32 Drivers: 7844 7845 - Serial: Add support for serial termios TCGET and TCSET. For the 7846 moment, only set/get speed is implemented. From Pierre-noel 7847 Bouteville. 7848 - RMU: Add support for the EFM32 reset management unit (RMU). From 7849 Pierre-noel Bouteville. 7850 7851 * SiLabs EFM32 Boards: 7852 7853 - Add support for timer/PWM on the EFM32GG. From Pierre-noel 7854 Bouteville 7855 7856 * STMicro STM32: 7857 7858 - Enable support for the STM32 F102. From the PX4 team. 7859 7860 * STMicro STM32 Drivers: 7861 7862 - STM32 F429 LTDC: Add interface to perform hardware accelerated layer 7863 operation. Provides access to a reference of a specific ltdc layer. 7864 From Marco Krahl 7865 - STM32 F429 LTDC support: Implemented LTDC framebuffer support for the 7866 generic nuttx framebuffer interface. Also implements the interface to 7867 perform hardware accelerated layer operation by the ltdc controller 7868 and dma2d controller later. From Marco Krahl. 7869 - STM32: Add support for the internal low speed clock (LSI) as a 7870 source of the RTC clock. Some boards do not have the external 7871 32kKhz oscillator installed, for those boards we must fallback to 7872 the crummy internal RC clock. From Kevin Hester 7873 - STM32 SDIO: Add support for the new SDWAIT_WRCOMPLETE condition. 7874 From David Sidrane 7875 7876 * STMicro STM32 Boards: 7877 7878 - Add a discrete Joystick support for the STM3210E-EVAL. 7879 - Add analog Joystick shield support for the Nucleo F4x1RE boards. 7880 - STM32 F429i-Disco: Add support for initializing of the ltdc 7881 controller and the lcd device connected on the stm32f429i-disco. 7882 From Marco Krahl. 7883 - Removed the px4-v2_upstream configuration. This was not the 7884 official configuration for the PX4 board and has led to confusion 7885 by NuttX users. The board configuration also requires some ongoing 7886 maintenance and customization to support ongoing PX4 testing and 7887 evaluation. It is best retained the PX4 repositories where it can 7888 be properly maintained and not in the upstream NuttX repository. 7889 7890 * TI Tiva: 7891 7892 - Add support for the TI Tiva TM4C 129X family. Some unverified 7893 support for the TM4C 1294 is also in place. 7894 7895 * TI Tiva Drivers: 7896 7897 - Added support for Tiva I2C driver. Verified on the Tiva TM4C123G 7898 and TM4C129X. 7899 - Added a Tiva TM4C129X Ethernet driver. 7900 - Add a timer library for generic support of Tiva timers 7901 - Add a driver lower half for drivers/timer.c. Only 32-bit periodic 7902 timers are supported. This provides userspace access to timers. 7903 7904 * TI Tiva Boards: 7905 7906 - TM4C123G Launchpad: Add initialization logic for an external AT24 7907 EEPROM. This is intended only to support testing of the Tiva I2C 7908 driver. 7909 - Board support for the Tiva DK-TM4C129x Connected Development Kit. 7910 - DK-TMC129X: Add an IPv6-enabled NSH configuration. 7911 7912 * C Library/Header Files: 7913 7914 - Added support for a variadic ioctl() function. The ioctl() 7915 interface is a non-standard, Unix interface. NuttX has always used 7916 the older, three-parameter version. Most contemporary systems now, 7917 however, use a variadic form of the ioctl() function. Added an 7918 option to insert a shim layer to adapt the three-parameter ioctl() 7919 to use the variadic interface form. Internally, the ioctl handling 7920 is the same three-parameter logic. The only real complexity to the 7921 shim is in how the system calls must be handled. 7922 - Added sys/custom_file.h. Used when CUSTOM_FILE_IO is define and 7923 avoids re-definition errors about the FILE define. From Thomas 7924 Gruber via the PX4 repository 7925 - Add CRC8 support to the C library. From Ken Pettit. 7926 - math.h: Added support for the expm1 functions. From Brennan Ashton 7927 7928 * Applications: 7929 7930 - apps/examples/djoystick: Add a test of the discrete joystick 7931 driver. 7932 - apps/examples/ajoystick: Add a test of the analog joystick 7933 driver. 7934 - apps/examples/ltdc: Add ltdc test example. From Marco Krahl 7935 - apps/system/lm75: Add a tiny application to read the temperature 7936 from an LM-75 (or compatible) temperature sensor 7937 - apps/examples/timer: Add a trivial test of the timer driver 7938 7939 - apps/system/cu: Add a minimalist implementation of the 'cu' 7940 terminal program (part of Taylor UUCP for ages). Using it, you can 7941 simply open a serial port and interact with it. Using '~.' you can 7942 leave the terminal program and drop back to nsh. This might come 7943 in handy for people that have e.g. GSM modems, GPS receivers or 7944 other devices with text based serial communications attached to 7945 their Nuttx systems. From Harald Welte 7946 - apps/interpreters/micropython: A port of Micro Python to NuttX. 7947 Contributed by Dave Marples 7948 7949 - apps/netutils/dnsclient: Can select to be either IPv4 or IPv6, but 7950 not both (IPv6 still does not compile) 7951 - apps/netutils/netlib: Add new library functions to manipulate IPv6 7952 addresses. 7953 - apps/examples/nettest: Update test so that it can be used to test 7954 IPv6 TCP sockets 7955 - apps/examples/udp: The UDP test example has been extend to support 7956 IPv6 domain sockets 7957 7958 - apps/nshlib: Add logic to initialize IPv6 addresses 7959 - apps/nshlib: Add the ping6 command to support checking IPv6 networks. 7960 - apps/nshlib: Clean up network status presentation for IPv6 7961 7962Efforts In Progress. The following are features that are partially 7963implemented but present in this release. They are not likely to be 7964completed soon. 7965 7966 * IPv6. While basic IPv6 support was completed in NuttX-7.7, 7967 there are lingering issues with getting IPv6 compatibility 7968 with applications and network utilities. 7969 7970 * Processes. Much of the work in this release is focused on the 7971 realization of Unix-style user processes in NuttX. There is more to 7972 be done, however. The full roadmap and status is available at: 7973 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 7974 7975 * XMega: There are some fragments in place for an XMega port. That 7976 port has not really started, however. 7977 7978 * Galileo: Similarly, there are fragments in place for an Intel Galileo 7979 port. The port probably will not happen (I gave my Galileo board away!). 7980 7981Bugfixes. Only the most critical bugfixes are listed here (see the 7982ChangeLog for the complete list of bugfixes and for additional, more 7983detailed bugfix information): 7984 7985 * Core OS: 7986 7987 - POSIX message queues: msg type should be char * not void * in 7988 mq_send, mq_timedsend, mq_receive, and mq_timedreceive. Noted by 7989 Pierre-Noel Bouteville 7990 - POSIX message queues: In message queue creation return ENOSPC error 7991 if size exceeds the configured size of pre-allocated messages; Use 7992 ENOSPC vs ENOMEM per OpenGroup.org. From Pierre-Noel Bouteville. 7993 - Task Names: strncpy() will not copy the terminating \0 into the 7994 destination if the source is larger than the size of the 7995 destination. Ensure that the last byte is always zero and let 7996 strncpy() only copy CONFIG_TASK_NAME_SIZE bytes. The issue of 7997 unterminated names can be observed in ps when creating a pthread 7998 while CONFIG_TASK_NAME_SIZE is set to 8. From Daniel Willmann 7999 8000 * Memory Management: 8001 8002 - Granule allocator: Fixes some issues found by the PX4 team using 8003 Coverity. From Pavel Krienko 8004 8005 * Networking: 8006 8007 - Several fixes correcting issues with the CC3000 networking. From 8008 Jussi Kivilinna 8009 - CC3000 Fix: Data can be unaligned. When dereferenced as an input 8010 ntosh(), a bad value is returned. Reported by Alan Carvalho de 8011 Assis 8012 - Correct naming of fields in struct sockaddr_in6: sin6_port and 8013 sin6_family, not sin_port and sin_family. 8014 - accept(): Correct the value returned by accept() in the case where 8015 net_lockingwait() is called. It was returning -1 and losing the 8016 errno value. Noted by Rony Xln 8017 8018 * Common Drivers: 8019 8020 - Loop device should return -EINTR is interrupted by a signal. 8021 - M25P serial flash driver: Add subsector size of the M24P16 part. 8022 From Lazlo 8023 - Common serial driver: In case a thread is doing a blocking operation 8024 (e.g. read()) on a serial device, while it is being terminated by 8025 pthread_cancel(), then uart_close() gets called, but the semaphore 8026 is still blocked. This means that once the serial device is opened 8027 next time, data will arrive on the serial port (and driver 8028 interrupts handled as normal), but the received characters never 8029 arrive in the reader thread. The problem was fixed by re- 8030 initializing the semaphores on the last uart_close() on the device. 8031 From Harald Welte 8032 - Pipes: Fixes some issues found by the PX4 team using Coverity. From 8033 Pavel Krienko 8034 - CDC/ACM driver: Fixes some issues found by the PX4 team using 8035 Coverity. From Pavel Krienko 8036 8037 * NXP LPC43xx Drivers: 8038 8039 - LPC4357: Changes required to get USART 2 & 3 working on the 8040 lpc4357-evb. From Toby Duckworth. 8041 8042 * STMicro STM32: 8043 8044 - Several fixes correcting issues with the STM32 header files from 8045 Jussi Kivilinna 8046 8047 * STMicro STM32 Drivers: 8048 8049 - Ported Tridge's STM32 I2C noise resilience logic from the PX4 8050 repository. 8051 - STM32 F2 and F4: Set the GPIO_SPEED_50MHz on all F2 and F4 SPI pin 8052 configurations. This is based on an F411 SPI1 errata but the fixed 8053 is generalized to all SPI and all F2 and F4. Discovered and fixed 8054 by Sebastien Lorquet. 8055 - Fix for STM32 OTGHS device driver working in FS mode. From Ken 8056 Pettit. 8057 - For STM32 OTG HS DEV (in FS mode): Disable ULPI clock enable in RCC 8058 AHB1 Register. If Both ULPI and the FS clock enable bits are set in 8059 FS mode, then the ARM never awakens from WFI due to a chip issue. 8060 This is only an issue if you are using the internal PHY. From Ken 8061 Pettit. 8062 - STM32 F429 LTDC: Add missing clut register definition. From Marco 8063 Krahl 8064 - STM32 serial: fix declaration and definition of up_receive() and 8065 up_dma_receive() to match fields in the interface definition of 8066 struct uart_ops_s. From Freddie Chopin. 8067 8068 * TI Tiva Drivers: 8069 8070 - Fix Tiva IRQ control logic; was limited to only 64 IRQs. That is a 8071 problem for higher numbered IRQs on many platforms 8072 8073 * C Library/Header Files: 8074 8075 - avsprintf(): Fix a bug in usage of va_list on x86. On x86, 8076 va_list is a pointer to a single copy on the stack. avsprintf() 8077 calls lib_vsprintf() twice and so traverses the va_list twice using 8078 va_start. va_start modifies that single copy on the stack so that 8079 the second call to lib_vsprintf() fails. This appears to be an 8080 issue with x86 only so far. 8081 - stdint.h: Don't use hex values to specify minimum values of fixed 8082 width, signed values. Hex values are inherently unsigned and not 8083 usable for this purpose in all contexts. 8084 - strncpy(): Would trash a lot of memory if n == 0. From Yasuhiro 8085 Osaki. 8086 - sscanf(). Accept %X and %F as well as %x %f as a format specifiers. 8087 From S�bastien Lorquet 8088 8089 * Applications: 8090 8091 - apps/examples/romfs: fix romfs example builtin app registry issue. 8092 From Librae 8093 - apps/system/cdcacm, composite and usbmsc: Fix some strangely placed 8094 conditional compilation. Looks like an automated update went awry 8095 - apps/netutils/telnetd: Add protection when CONFIG_SCHED_HAVE_PARENT 8096 is enabled: Call sigaction with SA_NOCLDWAIT so that exit status is 8097 not retained (no zombies) and block receipt of SIGCHLD so that 8098 accept is not awakened by a signal. If accept() is awakened by a 8099 signal, do not do anything crazy like exit. Most from Rony Xln 8100 - apps/nshlib/: NSH TFTP get command: Wrong file name used for the 8101 destination. From Lazlo 8102 8103NuttX-7.8 8104--------- 8105 8106The 108th release of NuttX, Version 7.8, was made on February 11, 2015, 8107and is available for download from the SourceForge website. Note 8108that release consists of two tarballs: nuttx-7.8.tar.gz and 8109apps-7.8.tar.gz. Both may be needed (see the top-level nuttx/README.txt 8110file for build information). 8111 8112This release is primarily a bugfix release for the NuttX-7.7 version that 8113was release just two weeks prior. That release included substantial 8114modifications in the NuttX networking to accommodate support for IPv6. This 8115release follows close behind NuttX-7.7 in order to correct some the problems 8116discovered in that networking code. This release does, however, include a 8117small number of new features and bug fixes unrelated to NuttX networking. 8118 8119Additional new features and extended functionality: 8120 8121 * Core OS: 8122 8123 - Tickless Mode: added limit of maximum delay that can be request 8124 by the scheduler tickless logic. This is necessary so that the 8125 tickless logic does not request a delay beyond the capability of the 8126 underlying hardware. From Macs Neklyudov. 8127 8128 * Common Drivers: 8129 8130 - VFS Unlink: Add an unlink method to both the character and block 8131 driver interface. This is important because if the driver inode is 8132 unlinked and there are no open references to the driver, then the 8133 driver resources will be stranded. On the unlink call, the driver 8134 has the opportunity (1) check if there an any open references, and 8135 if not, (2) free the driver resources. 8136 - Pipes and FIFOs: Implement the unlink method. If the pipe/FIFO is 8137 unlinked, it will marked the pipe/FIFO as unlinked. If/when all 8138 open references to the driver are closed, all of the driver 8139 resources will be freed. 8140 - Added an option to use the syslog'ing device as the system console. 8141 This option enables a low-level, write-only console device at 8142 /dev/console (similar to the low-level UART console device). From 8143 Pierre-noel Bouteville. 8144 8145 * File Systems/Block Drivers/MTD: 8146 8147 - RAM/ROM disk: Add logic to dispose of the driver and RAM buffer 8148 when the RAM disk has been unlinked and all open references to the 8149 RAM disk have been closed. Add new parameters to romdisk() to 8150 specify what should be done with the RAM/ROM buffer in this case -- 8151 Should it be freed or not? Changed all calls to ramdisk() to use 8152 these new parameters. 8153 8154 * Networking: 8155 8156 - Add support for local, Unix domain sockets. Support included for 8157 both SOCK_STREAM and SOCK_DGRAM style local socket. 8158 - UDP enhancement: Add UDP read-ahead support. In addition to 8159 eliminating the main reason for lost UDP packets, then change 8160 enables support for for poll/select on UDP sockets and also non- 8161 blocking UDP sockets. From Macs Neklyudov. 8162 - SLIP interface improvements. From Macs Neklyudov. 8163 - IPv6 Neighbor Solicitation: Added logic to support verification 8164 that we have the IPv6 address in the Neighbor Table before sending 8165 any packets. If not, then the Neighbor Solicitation message is 8166 sent. This feature is important because otherwise the first packet 8167 sent to a remote peer will fail (it would have been replaced with a 8168 Neighbor Solicitation). 8169 - IPv6 Autonomous Auto-Configuration: Added support for sending 8170 ICMPv6 Router Solicitation and receiving Router advertisement. The 8171 local IPv6 address, mask, and router address are then auto-configured 8172 from the response.. 8173 - IPv6 Router Support: Add logic to behave like a router (if so 8174 configured) only in the sense that NuttX will send the router 8175 advertisement message in response to any received router solicitation 8176 messages. Thus, one NuttX node in a network can configure the IPv6 8177 addresses of all other nodes in the network. 8178 - Optional IPv6 address filtering added to all Ethernet drivers for 8179 the all-routers multicast address. 8180 8181 * Atmel AVR: 8182 8183 - Added architecture support for the Atmel AVR ATMega1284P MCU. From 8184 Jedi Tek'Unum. 8185 8186 * Atmel AVR Boards: 8187 8188 - Added support for the LowPowerLab MoteinoMEGA that is based on the 8189 Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum. 8190 8191 * Atmel SAMA4: 8192 8193 - Add support for Tickless mode of operation for the SAM4CM platform. 8194 From Macs Neklyudov. 8195 8196 * Atmel SAMA4 Drivers: 8197 8198 - Ethernet: The SAM4E Ethernet driver can now be configuration to 8199 perform all network processing on the work queue. This greatly 8200 reduces the amount of interrupt level processing to service Ethernet 8201 packets. 8202 - SAM4E Ethernet: Add support multicast address matching and IPv6. 8203 8204 * Atmel SAMA4 Boards: 8205 8206 - SAM4E-EK: The nsh configuration now configures the Ethernet driver 8207 for execution on the work thread. 8208 8209 * Atmel SAMA5D Drivers: 8210 8211 - SAMA5D4 Ethernet: The SAMA5D4 Ethernet driver can now be configuration 8212 to perform all network processing on the work queue. This greatly 8213 reduces the amount of interrupt level processing to service Ethernet 8214 packets. 8215 - SAMA5D3 and SAMA5D4 Ethernet: Add support multicast address matching 8216 and IPv6. 8217 8218 * Atmel SAMA5D Boards: 8219 8220 - SAMA5D4-EK; Added a configuration to testing IPv6. 8221 - SAMA5D4-EK: Converted the nsh and ipv6 configurations to configure 8222 the Ethernet driver to use the work queue (vs. interrupt level 8223 processing). 8224 8225 * Freescale KL: 8226 8227 - Add architectural support for the K26Z128VLH4 chip. From Derek B. Noonburg. 8228 8229 * Freescale KL Boards: 8230 8231 - Add board support for the Freedom KL26Z board. From Derek B. Noonburg. 8232 8233 * NXP LPC17xx Drivers: 8234 8235 - Ethernet: Add support multicast address matching and IPv6. 8236 8237 * SiLabs EFM32: 8238 8239 - Add configurable option to unconditionally enable LE clocking. Even 8240 you don't use core clock LE as source for LFA or LFB, to read are 8241 write any register not clocked by HFPERCLK or HFCORECLK, HFCORECLKLE 8242 should be enabled. From Pierre-noel Bouteville. 8243 8244 * SiLabs EFM32 Drivers: 8245 8246 - EFM32 RTC: RTC driver using BURTC. From Pierre-Noel Bouteville. 8247 8248 * STMicro STM32 Drivers: 8249 8250 - AES: Add driver for STM32L162XX AES peripheral. From Juha Niskanen. 8251 - Ethernet: The STM32 Ethernet driver can now be configuration to 8252 perform all network processing on the work queue. This greatly 8253 reduces the amount of interrupt level processing to service Ethernet 8254 packets. 8255 - Ethernet: Add support multicast address matching and IPv6. 8256 8257 * STMicro STM32 Boards: 8258 8259 - Added an IPv6 configuration for the STM32F4-Discovery board (with the 8260 STM32-DISCO_BB base board). 8261 - Converted all STM32F4-Discovery configurations (with base board) to 8262 configure the Ethernet driver to use the work queue (vs. interrupt 8263 level processing). 8264 8265 * TI Tiva Drivers: 8266 8267 - Added support for TM4C123G timers. From Calvin Maguranis. 8268 - Added a Tiva ADC driver. From Calvin Maguranis. 8269 8270 * TI Tiva Boards: 8271 8272 - Added TM4C123G timers on the TM4C123G Launchpad. From Calvin Maguranis. 8273 - Added Tiva ADC support to the TM4C123G-Launchpad. From Calvin Maguranis. 8274 8275 * C Library/Header Files: 8276 8277 - Math Library: Added support for inverse hyperbolic functions, 8278 isfinite(), error functions, nan(), copysign(), and trunc() 8279 functions. From Brennan Ashton. 8280 8281 * Applications: 8282 8283 - apps/examples/ustream: Add a simple test of Unix domain stream 8284 sockets. 8285 - apps/examples/udgram: Add a simple test of Unix domain datagram 8286 sockets. 8287 - apps/netutils/netlib: Add utilities to convert to/from prefix 8288 lengths from/to 128-bit network masks. 8289 - apps/nshlib: Modify the NSH IPv6 ifconfig command to show the more 8290 standard post-pended prefix value, rather than the full 128-bit 8291 netmask. 8292 8293Efforts In Progress. The following are features that are partially 8294implemented but present in this release. They are not likely to be 8295completed soon. 8296 8297 * Processes. Much of the work in this release is focused on the 8298 realization of Unix-style user processes in NuttX. There is more to 8299 be done, however. The full roadmap and status is available at: 8300 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 8301 8302 * XMega: There are some fragments in place for an XMega port. That 8303 port has not really started, however. 8304 8305Bugfixes. Only the most critical bugfixes are listed here (see the 8306ChangeLog for the complete list of bugfixes and for additional, more 8307detailed bugfix information): 8308 8309 * Core OS: 8310 8311 - Work Queues: Fix a backward calculation when determining the time 8312 to the next interesting event. . From Liio Chen via the PX4 8313 repository. 8314 - clock_systimespec(): Fixes for compilation errors in certain 8315 configurations. From Macs Neklyudov. 8316 8317 * Graphics 8318 8319 - Fixed a problem with one of the font files. From Pierre-noel Bouteville. 8320 8321 * Networking: 8322 8323 - IOB Deadlock: There were issues with the TCP write-ahead buffering 8324 if CONFIG_NET_NOINTS was enabled: There is a possibility of 8325 deadlocks in certain timing conditions: The network should never 8326 wait for TCP read-ahead buffering space to be available. It should 8327 drop the packets immediately if no buffering is available. This was 8328 fixed by duplicating most of the IOB interfaces: The versions that 8329 waited are still present (like iob_alloc()), but now there are non- 8330 waiting versions of the same interfaces (like iob_tryalloc()). The 8331 TCP read-ahead logic now uses only these non-waiting interfaces. 8332 - TCP Deadlock: Fix another deadlock when CONFIG_NET_NOINTS is enabled. 8333 tcp_write_buffer_alloc() calls sem_wait() with network locked. That 8334 worked if CONFIG_NET_NOINTS was not defined because interrupts are 8335 automatically restored when the wait happens. But with 8336 CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad 8337 style and also can lead to a deadlock condition. 8338 - ARP response waiting: Fixes another CONFIG_NET_NOINTS issue. When 8339 called sem_timedwait() with the network locked, the network stays 8340 locked while we wait which is not what we want (without CONFIG_NET_NOINTS, 8341 interrupts are re-enabled while we wait and all is well). 8342 - TCP accept(): Fix a major TCP bug introduced with the NuttX-7.7 8343 IPv6 changes: Some connection logic was reordered; setting the 8344 socket as 'connected' got moved to BEFORE the point where the check 8345 was made if the socket was already connected. The resulting behavior 8346 was odd: Telnet would connect, but then when you exit and reconnect, 8347 it would fail to connect. But then if try again, it would connect 8348 okay. So the symptom was connect-fail-connect-fail-... 8349 - Lots of build problems introduced into multiple NIC support with the 8350 IPv6 changes of NuttX-7.7. Many places where conditional logic based 8351 on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. 8352 Lots of code changed with IPv6 that was never compiled with MULTINIC 8353 enabled. 8354 8355 * Common Drivers: 8356 8357 - Pipes and FIFOs: Fix a race condition between FIFO buffer operations 8358 and the opening and closing of FIFOs which necessary when the FIFOs 8359 are used to support Unix domain, datagram sockets. The default 8360 policy is the deallocate FIFO buffering when the last client closes 8361 the pipe. When when used for datagram communications, packets left 8362 in the FIFO will be lost. Some like UDP read-ahead is needed: The 8363 buffered data in the FIFO needs to be retained until the reader gets 8364 a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to 8365 control the buffer policy. Default (0) is the legacy behavior; Unix 8366 domain datagram logic sets the alternative policy so that the packet 8367 data persists after the FIFO is closed. 8368 - RAMTRON: Table of parts is not terminated properly if 8369 CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined. Noted by David 8370 Sidrane. 8371 8372 * All Architectures: 8373 8374 - Removed all occurrences of up_maskack_irq() that disables interrupts 8375 with up_ack_irq() that only acknowledges the interrupts. This is only 8376 used in interrupt decoding logic. Also remove the logic that 8377 unconditionally re-enables interrupts with the interrupt exits. This 8378 interferes with the drivers ability to control the interrupt state. 8379 This is a necessary, sweeping, global change and unfortunately 8380 impossible to test. 8381 8382 * ARM 8383 8384 - ARMv7-A and ARMv7-M memcpy(): Optimized ARM assembly language 8385 memcpy's were not returning a value in R0 they are required to do. 8386 From David Sidrane. 8387 - ARMv7-A interrupt handler should not automatically re-enable interrupts 8388 on interrupt return. That interferes with the driver's ability to 8389 manage interrupts. Analogous change made to all other architectures 8390 as well (ARM7, ARM9, HC, SH, x86, z16, z80, etc,. See above.). 8391 8392 * STMicro STM32: 8393 8394 - GPIO Interrupts: Disabling any of EXTI 5-9 interrupts was disabling 8395 interrupts for all EXTI 5-9. Same issue with EXTI 10-15. From Jussi 8396 Kivilinna. 8397 8398 * STMicro STM32 Drivers: 8399 8400 - RTCC: Fix for recent changes that caused compilation failrues with 8401 STM32L15XX configurations. From Jussi Kivilinna. 8402 - SPI: The source clock for SPI 4,5, and 6 should be PCLK2, not PCLK1 8403 (for F411, F427, and F429). Per David Sidrane. 8404 8405 * C Library/Header Files: 8406 8407 - execl(): Fix bad logic in counting the number of arguments. 8408 execl() parameter passing could never have worked. Noted by 8409 Pierre-noel Bouteville. 8410 8411 * Applications: 8412 8413 - Fix for building with parallel make. Build-server sometimes failed 8414 'make -j24' with errors in the builtin line or or sometimes silently 8415 succeeds but generated builds that contain a random subset of 8416 configured NuttX applications. There are two root causes for this: 8417 (1) Recipes for building builtin_list.h and builtin_proto.h are 8418 not linearizable, and (2) Nothing ensures that 'make context' is run 8419 first for apps/builtin. This change address both issues. From Juha 8420 Niskanen. 8421 8422NuttX-7.9 8423--------- 8424 8425The 109th release of NuttX, Version 7.9, was made on April 14, 2015, 8426and is available for download from the SourceForge website. Note 8427that release consists of two tarballs: nuttx-7.9.tar.gz and 8428apps-7.9.tar.gz. Both may be needed (see the top-level nuttx/README.txt 8429file for build information). 8430 8431Additional new features and extended functionality: 8432 8433 * Core OS: 8434 8435 - Assertions: Add support for dumping board-specific information on 8436 assertions. From David Sidrane. 8437 - boardctl(): : Add a new non-standard OS interface called boardctl(). 8438 This is similar to a driver IOCTL call. But this is an IOCTL call 8439 directly on the board logic. This function will eventually replace 8440 all of the ad hoc OS interfaces that are current used to perform 8441 application specific initialization and application driver test 8442 configuration. It essentially formalizes and institutionalizes 8443 these rogue interface in to at least a single crazy call. 8444 8445 * Graphics: 8446 8447 - Line Joins: Line drawing graphic functions now take an argument that 8448 will draw a circular "cap" on the ends of lines to support cleaner 8449 joining of lines segments.. 8450 8451 * Common Drivers: 8452 8453 - SPI iInterface: Add an SPIDEV_USER so that there can be board- 8454 specific definitions of SPI devices. 8455 - I2C Interface: Add a user provided void * argument to the I2C 8456 callback method for the I2C slave interface. Suggested by Nate 8457 Weibley. 8458 - AT24 EEPROM Driver: Add support for (1) the byte-oriented read() 8459 method, (2) devices that have extended memory regions, and (3) 8460 devices that use 8-bit addressing. 8461 - Freescale MPL115A barometer: Add driver for the Freescale MPL115A 8462 barometer. From Alan Carvalho de Assis. 8463 - CS2100-CP: Add a driver for the CS2100-CP Fractional-N Multipler 8464 chip. 8465 - RTC IOCTls: Added the definitions of a driver based RTC interfaces 8466 and RTC upper half driver. 8467 8468 * File Systems/Block Drivers/MTD: 8469 8470 - umount2(): Added to support un-mount flags. umount() is now a macro 8471 that just calls umount2() with flags = 0. 8472 - File system interface: Pass the umount2() flags to every unbind() 8473 implementation. That is where the decision to umount or not and how 8474 to umount will be made. 8475 - FAT unbind: Add support for umount2(target, MNT_FORCE) in the FAT 8476 file system. 8477 8478 * Networking: 8479 8480 - netdev_register(): Improve the network device registration logic. 8481 When multiple link types are used, modify how each interface number 8482 is assigned to the device name by incrementing the device number 8483 individually for each interface link type. From Max Neklyudov. 8484 - Add TUN network device. Used to support the Netutils PPPD 8485 implementation. From Max Neklyudov. 8486 8487 * ARMv7-M 8488 8489 - ARM Cortex-M7: Add basic support for the Cortex-M7 architecture. 8490 - ARMv7 Common Lazy Exception handling. Add common support for lazy 8491 FPU state saving. MCU-specific lazy FPU saving was already in place. 8492 This change just makes the code share-able. 8493 8494 * Atmel SAMA5D3/4 Drivers: 8495 8496 - SAMA5 Serial: Backport support for flowcontrol and termios from 8497 SAM3/4. 8498 8499 * Atmel SAMV7: 8500 8501 - Atmel SAMV7: Add architecture support for the Atmel SAMV7 family 8502 (Cortex-M7) 8503 8504 * Atmel SAMV7 Boards: 8505 8506 - Atmel SAMV71 Xplained Ultra: Add board support for this SAMV7 board. 8507 This initialize release includes support for: SDRAM, TWI/I2C, SPI, 8508 Ethernet, HSMCI, DMA, GPIOs, UARTs, AT24 EEPROM and the maXTouch 8509 Xplained Pro LCD. Drivers are available for SSC/I2C, the WM8904, 8510 the maXTouch trouchscreen, and USB device but have not yet been 8511 fully integrated in this release. 8512 8513 * SiLabs EFM32 Drivers: 8514 8515 - EFM32 USB Device is now functional with the efforts of From Pierre- 8516 noel Bouteville. 8517 - EFM32 I2C: Add I2C driver. From Pierre-noel Bouteville. 8518 8519 * STMicro STM32: 8520 8521 - STM32F372/F373: Adds architecture support for this STM32 parts. 8522 Tested on STM32F373CC. Contributed by Marten Svanfeldt. 8523 8524 * STMicro STM32 Drivers: 8525 8526 - STM32 RTCC: Break out a new internal interface, stm32_rtc_setdatetime(). 8527 This eliminates some un-necessary time conversions. From Freddie Chopin. 8528 - STM32 RTCC: Add an implementation of the RTC lower half interface 8529 for the STM32. 8530 - STM32 RTCC: Extend the RTC interface to support reading subseconds. 8531 From Jussi Kivilinna. 8532 - STM32 BBSRAM: Adds the ability to use the STM32F2 and STM32F4 Battery 8533 Backed SRAM in the file system. With an option to Save Panic context 8534 to one of the files. From David Sidrane. 8535 8536 * STMicro STM32 Boards: 8537 8538 - Olimexino-STM32: Board support for the Olimexino STM32 board from David 8539 Sidrane. 8540 - Viewtool-STM32F107: Add support for an optional, add-on Freescale 8541 MPL115A baramoter. From Alan Carvalho de Assis. 8542 8543 * TI Tiva: 8544 8545 - TM4C1294: Add support for the TM4C1294. Contributed by Frank Sautter. 8546 8547 * TI Tiva Drivers: 8548 8549 - Tiva ADC: Updated files to allow for ADC and PWM triggering by a 8550 timer. Refactoring of ADC implementation. From Calvin Maguranis. 8551 - Tiva Timer: Refactoring by Calvin Maguranis 8552 8553 * TI Tiva Boards: 8554 8555 - TM4C123G-launchpad: Add ADC support. From Calvin Maguranis. 8556 - TM4C123G-launchpad: Add board button interrupt support. From Calvin 8557 Maguranis. 8558 - TM4C1294 Launchpad: Add support for the TM4C1294 Launchpad. 8559 Contributed by Frank Sautter. 8560 8561 * Microchip PIC32 8562 8563 - PIC32MZ: Add architectural support for the PIC32MZ (MIPS32 M14k). 8564 Includes contributions from Kristopher Tate. 8565 8566 * Microchip PIC32MZ Boards 8567 8568 - PIC32MZ Starter Kit: Add basic board support for the PIC32MZ. 8569 Includes contributions from David Sidrane. 8570 8571 * C Library/Header Files: 8572 8573 - gettimeofday(): This function is no longer a core OS interface. It 8574 is only a wrapper around clock_settime(). 8575 - settimeofday(): Added. gettimeofday has been deprecated in POSIX 8576 2008. settimeofday() was never part of POSIX, but I decided to add 8577 it to libc as well just for symmetry. 8578 - Day-of-Week: Add CONFIG_TIME_EXTENDED to support the last 3 members 8579 of the tm struct and support for filling them in with the day of the 8580 week. From David Sidrane. 8581 - sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New 8582 signal handling functions. 8583 - sys/select.h: Extend the fd_set type definition so that it can 8584 handle more than 32 descriptors (if so configured). From Max 8585 Neklyudov. 8586 - netdb.h: Add a mostly-commented-out version of the standard netdb.h 8587 header file. 8588 - include/nuttx/board.h: Remove common board function prototypes from 8589 other files and consolidate them in this new header file. 8590 8591 * Applications: 8592 8593 - OS test: Improved error checking for sem_timedwait() from Juha 8594 Niskanen. 8595 - OS test: Add a simple test of sigprocmask, sighold, and sigrelse. 8596 - PPPD test: Add PPPD test case. Split out from the PPPD daemon by 8597 Brennan Ashton. 8598 - Netutils: Add a PPP daemon. From Max Neklyudov. 8599 - NSH: NSH initialization now calls boardctl(BOARDIOC_INIT) instead 8600 of nsh_archinitialize(). Remove support for CONFIG_NSH_ARCHMAC. 8601 It is not used and there are better ways to do that operation. 8602 - NSH: Allow NSH 'date' command with no hardware RTC. This command 8603 is useful without an RTC too. Also, this permits testing on the 8604 simulator which never has an RTC. 8605 - apps/examples/: Several tests changed (touchscreen adc, pwm, 8606 graphics). No longer call directly into the OS, but rather 8607 indirectly via boardctl(). 8608 - Modbus: Includes extensions to support RTU master mode by 8609 Armink(383016632@qq.com): https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32. 8610 Ported to NuttX by Darcy Gong. 8611 - TZ database: All logic to build timezone database needed for 8612 localtime() support. Does not do much else yet. 8613 8614Efforts In Progress. The following are features that are partially 8615implemented but present in this release. They are not likely to be 8616completed soon. 8617 8618 * Processes. Much of the work in this release is focused on the 8619 realization of Unix-style user processes in NuttX. There is more to 8620 be done, however. The full roadmap and status is available at: 8621 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 8622 8623 * XMega: There are some fragments in place for an XMega port. That 8624 port has not really started, however. 8625 8626Bugfixes. Only the most critical bugfixes are listed here (see the 8627ChangeLog for the complete list of bugfixes and for additional, more 8628detailed bugfix information): 8629 8630 * Core OS: 8631 8632 - atexit(): Fix compile failure due to reference to undefined variable 8633 in certain configurations. From Juha Niskanen. 8634 - syscalls: Last changes to message queue prototypes did not make it 8635 into call gate logic. Some additional errors had crept as well since 8636 the system calls are seldom used. 8637 - waitpid(): Do not use uninitialized boolean in waitpid(). From Juha 8638 Niskanen. 8639 - Timing functions: Fix some nanosecond comparisons. Comparisons should 8640 be greater than OR EQUAL TO 1000000000 for maximum value of nanoseconds 8641 in struct tm. From Juha Niskanen. 8642 - Time initialization: Fix an error in time initialization when there 8643 is no RTC and the time is initialized from a fixed configured value. 8644 The call to clock_calendar2utc() was returning the time in units of 8645 seconds. The initialization logic, however, was expecting to get 8646 time in units of days. This problem has been there forever but 8647 obviously has not significant impact to behavior in systems where 8648 time is not visible. 8649 - mq_timedsend(): Should not check for valid time if there is space 8650 in the message queue. Noted by Freddie Chopin. 8651 - select() and sem_timedwait(): Fix places where the errno value was 8652 being overwritten by subsequent actions so that the returned errno 8653 value was incorrect. From Max Neklyudov. 8654 - clock_systimer64(): Fix a problem in clock_systimer64 that occurs 8655 when (1) the 64-bit system time is enabled, and (2) the value of 8656 CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using 8657 the tickless mode of operation). In that case, the conversion of 8658 time to 64-bit millisecond value in clock_systmer64() causes some 8659 bad times to be returned. Time was converted to milliseconds, then 8660 to configured ticks. Precision was lost in the millisecond 8661 conversion. The fix is to first convert time to a 64-bit microsecond 8662 value, then to the configured tick value. Noted by David Sidrane. 8663 - clock_systimespec(): When an RTC is used clock_systimespec() must 8664 subtract the basetime from the returned time. It needs to return 8665 the time since power up, no the current time. Issue noted by Max 8666 Neklyudov. 8667 - AIO: correct some backward tests in aio_read() and aio_write(): 8668 Socket descriptors have higher numbers than file descriptors. In 8669 aio_contain(), Copy u.ptr (void *) when initializing aioc and not 8670 the case specific u.aioc_filep. From Michal Ulianko. 8671 8672 * File Systems/Block Drivers/MTD: 8673 8674 - procfs: Fix potential NULL pointer dereference of 'node'. From 8675 Juha Niskanen. 8676 - FAT: fat_unbind() was accessing 'fs->fs_sem' after freeing the 'fs' 8677 struct. From Juha Niskanen. 8678 - mkfatfs: Use DMA memory for mkfatfs when needed. This makes mkfatfs 8679 use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is needed 8680 to ensure mkfatfs operates with boards that use DMA for microSD. 8681 From Andrew Tridgell via the PX4/NuttX repository. 8682 - FAT unmount: Fix a bug in the FAT unbind() logic. There were 8683 problems with the way certain internal list handling was 8684 implemented. The end result is that newly opened or cloned file 8685 structures were never being added to the list of open files. So 8686 when the unmount() happens, it always looked like there were not 8687 open files and a crash could ensue. 8688 - FAT mounting: Fix misthink when CONFIG_ENDIAN_BIG=y. From Lwazi Dube. 8689 8690 * Common Drivers: 8691 8692 - CAN upper half driver: Some lines had to be reordered in the can_open 8693 function otherwise the open count will only be incremented from 0 to 8694 1. This caused problems when trying to open the can bus from two 8695 different tasks. SourceForge Patch #46. 8696 8697 * Crypto: 8698 8699 - crypto: Fix issues when AES support was added for the STM32L1. 8700 From Juha Niskanen. 8701 8702 * Networking: 8703 8704 - Network initialization: Divide net_intiialize() into net_setup() and 8705 net_initialize() to solve a chicken-and-egg problem. net_setup() 8706 must be called before up_initialize() is called so that networking 8707 data structures are ready to register new network devices. 8708 net_initialize() now does only timer related operations and is 8709 called AFTER up_initialize() where the timers are configured. 8710 Problem noted by Max Neklyudov. 8711 - netdev_unregister(): Fix a list handling error. From Max Neklyudov. 8712 - Socket dup: Do not call sockfd_socket() twice. From Juha Niskanen. 8713 8714 * Common Drivers: 8715 8716 - max11802 touchscreen: Fix possible unmatched IRQ restore (not 8717 normally a problem, but could happen in certain configurations). 8718 Noted by Juha Niskanen. 8719 - MMCSD SPI Multi-block transfers: ACMD23 must be preceded with CMD55 8720 command as any other ACMD commands. Also, after the block reading 8721 wait loop must be inserted before writing the next block of data to 8722 the sd card. From Dmitry Nikolaev via Jussi Kivilinna. 8723 - MMCSD SDIO: Fix some bad logic when file system debug is turned on: 8724 Arguments to syslog were missing so that garbage was being printed. 8725 - Common upper-half serial driver: Report correct number of bytes free 8726 in serial buffer with FIONWRITE. From Sami Pelkonen via Jussi Kivilinna. 8727 - Pipes/Fifos: Fix zero-lenth writes to pipes/FIFOs. From Jussi Kivilinna. 8728 - USB device MSC: Add NULL pointer check. From Juha Niskanen. 8729 - BCH driver: Avoid NULL pointer dereference when bch->refs == 255. 8730 From Juha Niskanen. 8731 - Various drivers: The inode unlink method should not be support if 8732 operations on the root pseudo-filesystem are disabled. 8733 8734 * ARMv7-M 8735 8736 - ARMv7M MPU: Bad syntax in ARMv7-M MPU logic would cause failure to 8737 write the correct value to the MPU_RASR register. From Juha Niskanen. 8738 8739 * Atmel SAM3/4 Drivers: 8740 8741 - SAM3/4 Serial TERMIOS: A side-effect of changing serial settings 8742 via TERMIOS (such as tcsetattr) is that serial interrupts were being 8743 left disabled. This is not a problem if the serial configuration is 8744 changed when there are no open references to the serial device. In 8745 that case, serial interrupts are disabled and will not be enabled 8746 enabled until the serial device is first opened. But it is fatal if 8747 the serial device is already opened and if there is a task waiting 8748 to receive data. In that case, the side-effect of disabling 8749 interrupts is fatal: That task is then left hanging with interrupts 8750 disabled. 8751 - SAM3/4 Serial: The IMR register is read-only. This means that 8752 sam_restoreints() did not actually re-enable UART interrupts 8753 (Fortunately, that function was not being used up to this point). 8754 - SAMA5 HSMCI: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift 8755 values were reversed resulting in a trashed value for the number of 8756 blocks in the BLOCKR register. This was sufficient to prevent DMA 8757 writes from working. 8758 8759 * Atmel SAMA5 Drivers: 8760 8761 - SAMA5 Timer/Counter: Fix typos in timer/counter header file. From 8762 Bob Doiron. 8763 8764 * STMicro STM32 Drivers: 8765 8766 - STM32 PWR and RTC: Changes to support fully write protecting the 8767 backup domain. N.B. stm32_pwr_enablebkp did not account for the delay 8768 from enable to the domain being writable. The KISS solution is a 8769 up_udelay. A more complex solution would be a negated write test 8770 with restore. From David Sidrane. 8771 - STM32 SPI: Add missing SPI callback functions to the STM32 SPI 8772 driver. From Freddie Chopin. 8773 - STM32 I2C: Add missing NULL check. From Juha Niskanen. 8774 - STM32 USB device: Fix stale initialization invalidating later NULL 8775 check. From Juha Niskanen. 8776 - STM32 UART: Fix RX DMA setup for UART5. From Jussi Kivilinna. 8777 - STM32 UART: Make input hardware flow-control work with RX DMA. From 8778 Jussi Kivilinna. 8779 - STM32 RTC and clock control: The STM32F4Discovery board doesn't 8780 come with a Low speed external oscillator so the default LSE source 8781 for the RTC doesn't work. In stm32_rtcc.c the up_rtc_initialize() 8782 logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R 8783 register lead to rtc_setup() call that rightfully enables the LSI 8784 clock; but the next times, when the rtc is already setup, the 8785 rtc_resume() call does NOT start the LSI clock! The right place to 8786 put LSE/LSI initialization is inside stm32_stdclockconfig() in 8787 stm32fxxxxx_rcc.c. Doing this I checked the possible uses of the 8788 LSI and the LSE sources: the LSI can be used for RTC and/or the 8789 IWDG, while the LSE only for the RTC (and to output the MCO1 pin). 8790 This change is not verifed for any other platforms. From Leo 8791 Aloe3132 8792 8793 * Tiva Drivers: 8794 8795 - Tiva GPIO driver needed small fixes in the configuration routines and 8796 discovered false-positive bugs in interrupt testing: interrupts are 8797 now verified to actually be working reliably. From Calvin Maguranis . 8798 8799 * MIPS32: 8800 8801 - mips32/Toolchain.mk: Current Pinguino toolchain uses the prefix p32- 8802 instead of mips-. 8803 8804 * C Library/Header Files: 8805 8806 - sigaddset() and sigdelset(): Need to set errno if a bad signal 8807 number is received. 8808 - sfrtime(): Missing implementation of %C in sfrtime() C (was being 8809 treated as %y). From Freddie Chopin. 8810 - pthread.h: Fix PTHREAD_COND_INITIALIZER. 8811 - ungetc.c: Fix NULL pointer dereference in ungetc() if 'stream' was 8812 NULL, 'stream->fs_oflags' was evaluated. From Juha Niskanen. 8813 - Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all 8814 exhibited bad cancellation errors near zero (<= 1E-10). This can be 8815 easily seen e.g. with x = 1E-30, the results are all zero though they 8816 should be extremely close to x. The cutoff values (1E-5, 1E-9) are 8817 chosen so that the next term in the Taylor series is negligible (for 8818 double). Functions could maybe be optimized to use only first term (x) 8819 and a smaller cutoff, just bigger than where the cancellation occurs 8820 - localtime(): Inconsistent configuration name: CONFIG_LIBC_TZDIR vs 8821 CONFIG_LIBC_TZ_TZDIR. Former wins. 8822 8823 * Applications: 8824 8825 - Modbus: Fix some compile problems when TCP is enabled. 8826 8827NuttX-7.10 8828---------- 8829 8830The 110th release of NuttX, Version 7.10, was made on June 9, 2015, 8831and is available for download from the SourceForge website. Note 8832that release consists of two tarballs: nuttx-7.10.tar.gz and 8833apps-7.10.tar.gz. Both may be needed (see the top-level nuttx/README.txt 8834file for build information). 8835 8836Additional new features and extended functionality: 8837 8838 * Binary Loader: 8839 8840 - ARMv-7M, binfmt/, STM32: Add support uClibc++ exceptions. This 8841 involved additional handling for relative relation types, additional 8842 support for unwinding, as well as additional changes. The 8843 culmination of a big effort from Leo Aloe3132. 8844 8845 * Graphics/Graphic Drivers: 8846 8847 - RA8875 LCD driver contributed by Marten Svanfeldt. 8848 8849 * File Systems/Block Drivers/MTD: 8850 8851 - Union File System: Add support for a union file system that can be 8852 used to overlay and merge the content of two mounted file systems. 8853 8854 * USB Host: 8855 8856 - USB Hub Support: Bring in USB hub-related files from 8857 https://github.com/kaushalparikh/nuttx. This is the work of Kaushal 8858 Parikh. This is quite a bit more hub logic was needed in before the 8859 USB hub support was fully functional. This involved changing many 8860 USB host controller driver interfaces and modifications to many 8861 drivers. 8862 - USB host CDC/ACM class driver: Added initial implementation of a 8863 host-side CDC/ACM driver. Initial version was a great learning 8864 experience, but probably should be partially redesigned (as 8865 discussed in the top-level TODO file). 8866 - IPv6 Routing: Complete implementation of the IPv6 routing logic. 8867 From Max Neklyudov. 8868 8869 * Networking: 8870 8871 - Local Sockets: Add poll support for Unix stream sockets. From Jussi 8872 Kivilinna. 8873 - net/: ARP, ICMP, ICMPv6, PKT, TCP, and UDP now all receive event 8874 notifications from both network device packet processing, but now 8875 also from Device-specific events such as when the network goes down. 8876 The device notification callback structure is now supports dual 8877 linkages so that the client can receive notifications from both 8878 source; The device structure now includes a list of clients that 8879 want to receive device related notifications. This prevents network 8880 actions from hanging when the device goes down and will be an 8881 essential part of future support for removable network devices. 8882 Some of the core logic was contributed by Max Neklyudov. 8883 - TUN: Misc. improvements to the TUN driver, mostly related to poll(). 8884 Also several bugfixes. From Max Neklyudov. 8885 8886 * Simulation Platform: 8887 8888 - Simulator: Add logic to test localtime and TZ database. See 8889 apps/system/README.txt for info. 8890 - Simulation: Add a configuration for testing the Union File System. 8891 8892 * Calypso: 8893 8894 - Calypso Compal-E86: Updates for execution out of FLASH on the C139 8895 phone. From Craig Comstock. 8896 8897 * Atmel SAMD/L: 8898 8899 - SAML21 Support: And chip definitions, configuration framework, 8900 memory map and pin configuration files for SAML21 support. 8901 8902 * Atmel SAMD/L Boards: 8903 8904 - SAML21-Xplained: Add a board support for the SAML21 Xplained Pro. 8905 This is based on the similar SAMD20 Xplained Pro board. 8906 8907 * Freescale/NXP KL: 8908 8909 - KL25Z64: Added support for the KL25Z64. The KL25Z64 is a lower 8910 memory variant of the KL25Z128 and is used on the Teensy LC. From 8911 Michael as SourceForge patch 50. 8912 8913 * Freescale/NXP KL Boards: 8914 8915 - Teensy-LC: Add board support for the Teensy LC board. Support is 8916 based off the Freedom KL25Z board. LED, PWM, and UART0 have been 8917 tested. The SPI pins are mapped correctly but have not yet been 8918 tested. From Michael Hope as SourceForge patch 51. 8919 8920 * NXP LPC111x: 8921 8922 - LPC111x: Support for the LPC11xx family (the LPC1115 MCU in 8923 particular). Contributed by Alan Carvalho de Assis. 8924 8925 * NXP LPC111x Boards: 8926 8927 - LPCXpresso LPC1115: Support for the LPCXpression LPC1115 8928 board. Contributed by Alan Carvalho de Assis. 8929 8930 * NXP LPC17xx Drivers: 8931 8932 - LPC17xx Ethernet: Add support for the Micrel KSZ8041 PHY to the 8933 LPC17xx Ethernet driver. 8934 8935 * NXP LPC17xx Boards: 8936 8937 - Lincoln60: Add a network enabled configuration for the Lincoln60 8938 board. 8939 8940 * Atmel SAM3/4 Drivers: 8941 8942 - SAM4CM: Add support for optical mode for the SAM4CM UART1. From 8943 Max Neklyudov. 8944 8945 * Freescale (NXP) Kinetis: 8946 8947 - Kinetis K20: Basic support for the Kinetis K20 architecture. Taken 8948 from PX4. This is the work of Jakob Odersky. 8949 8950 * Atmel SAMV7 Boards: 8951 8952 - SAMV71-Xplained w/maXTouch Xplained Pro: A TWIHS fix was the last 8953 barrier to getting the touchscreen working in the maXTouch Xplained 8954 Pro LCD. Added the NxWM integrated graphics demonstration 8955 configuration. 8956 8957 * STMicro STM32: 8958 8959 - STM32: Added support for STM32F302K8 and STM32F302K6. From Ben Dyer 8960 via PX4/David Sidrane. 8961 - STM32F205RG: Add basic support for the STM32F205RG. From SourceForge 8962 Ticket 40 (anonymous, 2015-05-31). 8963 - STM32 F3: Add DBGMCU register definitions for the F3 family. From 8964 Greg Meiste. 8965 8966 * STMicro STM32 Drivers: 8967 8968 - STM32 LCDC: Defined a second interface for the dma2d controller. 8969 LTDC only controls the display visibility but the DMA2D controller 8970 changes the content of the frame buffer (buffer of the layer). From 8971 Marco Krahl. 8972 - STM32 PVD: Added support for STM32's Programmable Voltage Detector 8973 (PVD) feature. By Dmitry Nikolaev, submitted by Juha Niskanen. 8974 8975 * STMicro STM32 Boards: 8976 8977 - STM32F429i-Disco: Add support for the new DMA2D features to the LTDC 8978 configuration. From Marco Krahl. 8979 8980 * TI Tiva Boards: 8981 8982 - TM4C1294 Launchpad: Added TM4C1294NCPDT EN0_LED2 (10/100-Base-Tx); 8983 removed all booster pack pin definitions. From Frank Sautter. 8984 8985 * C Library/Header Files: 8986 8987 - libc: Add an option to disable support for long long formats in 8988 lib_vsprintf(). On very tiny platforms, this reduces the footprint 8989 by omitting large libgcc.a libraries to perform the 64-bit 8990 arithmetic operations. From Alan Carvalho de Assis. 8991 8992 * Applications: apps/system: 8993 8994 - nuttx/zoneinfo: Add logic to build a ROMFS file system 8995 containing the timezone data. 8996 8997 * Applications: apps/nshlib: 8998 8999 - Add poll support for Unix stream sockets. From Jussi Kivilinna. 9000 - Enhancements to NSH ifconfig for case of multi-link operation, TUN 9001 device and local connections. From Max Neklyudov. 9002 - Enhanced output to NSH ping command from Max Neklyudov. 9003 - The NSH mount command now recognizes the Union filesystem type when 9004 listing mounted file systems. 9005 9006 * Applications: apps/netutils: 9007 9008 - apps/netutils/thttpd/ and apps/examples/thttpd/: Add support for 9009 using binfs/ with the Union FS instead of NXFLAT. NXFLAT is 9010 probably the better solution but recently compiler changes make it 9011 unusable. binfs or ELF are fallback binary formats. This commit 9012 adds an option to use binfs with the Union FS. 9013 9014 * Applications: apps/examples: 9015 9016 - Modify/simpify apps/examples build files. From Roman Saveljev. 9017 - apps/examples/ltdc: Add testing support for the STM32 LTDC's 2D DMA. 9018 From Marco Krahl. 9019 - apps/examples/ostest: Add a test of nested signals. There are no 9020 failures to handle signals but neither am I getting any nested signal 9021 handling. 9022 - apps/examples/elf: Add configuration options to support building the 9023 hello++4 example that depends upon having uClibc++ available. Also 9024 add hello++5 to the ELF example From Leo aloe3132. 9025 - apps/examples/unionfs: Add a test of the union file system to 9026 apps/examples. 9027 9028Efforts In Progress. The following are features that are partially 9029implemented but present in this release. They are not likely to be 9030completed soon. 9031 9032 * Processes. Much of the work in this release is focused on the 9033 realization of Unix-style user processes in NuttX. There is more to 9034 be done, however. The full roadmap and status is available at: 9035 http://www.nuttx.org/doku.php?id=wiki:nxinternal:memconfigs#the_roadmap_toward_processes 9036 9037 * XMega: There are some fragments in place for an XMega port. That 9038 port has not really started, however. 9039 9040Bugfixes. Only the most critical bugfixes are listed here (see the 9041ChangeLog for the complete list of bugfixes and for additional, more 9042detailed bugfix information): 9043 9044 * Core OS: 9045 9046 - boardctl(): Add missing case causing that caused failures of PWM 9047 test. 9048 - pthread_kill(): Re-implemented pthread_kill(). It was just a simple 9049 wrapper around kill() but since the correct dispatching of signals 9050 for multi-threaded task groups has been implemented, calling kill() 9051 does not do what pthread_kill() is supposed to do. The corrected 9052 implementation of pthread_kill() will direct the signal specifically 9053 to the specific pthread and no other. 9054 - uint32_t callbacks: Update the type passed to watchdog timer 9055 handlers. Using uint32_t is a problem for 64-bit machines because 9056 it it too small to pass a pointer. uintptr_t is a more appropriate 9057 type. 9058 - mq_timedreceive(): move the location where the errno value is set; 9059 the ETIMEDOUT errno setting was being overwritten by subsequent 9060 actions before returning. Noted by Freddie Chopin. 9061 - POSIX message queues: Move mq_setattr() and mq_getattr() from 9062 nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support 9063 for mq_setattr() and mq_getattr(). This is necessary in protected 9064 and kernel builds because in those cases the message queue 9065 structure is protected and cannot be accessed directly from user 9066 mode code. 9067 9068 * File Systems/Block Drivers/MTD: 9069 9070 - MTD: Increase the size of the fields in the geometry structure 9071 (again) to support larger FLASH sizes. Needed by Sebastien Lorquet. 9072 9073 * Common Drivers: 9074 9075 - poll(): Fix resource leak and memory corruption on poll failure. 9076 From Jussi Kivilinna. 9077 9078 * USB Host: 9079 9080 - LPC31xx and SAMA5Dx EHCI: Fix cache related problem in LPC31 and 9081 SAMA5Dx EHCI drivers. All buffers are now aligned with the cache 9082 line size in both starting address and in length. This cause major 9083 problems in unlucky builds where the USB host buffers where 9084 unaligned and abutting other data. The cache flush and invalidate 9085 operations could be subverted by accesses to adjacent data or could 9086 have unexpected side effects. This bug has been in the ECHI drivers 9087 forever, but was only revealed due to unlucky memory allocations 9088 during the integration of the hub feature. 9089 9090 * USB Device: 9091 9092 - All USB device class drivers: There needs to be a check to make 9093 sure that the size of a returned string does not exceed the size of 9094 the allocated request buffer. Strings such as vendor names or 9095 product names will be truncated to fit in the request buffer. 9096 9097 * Networking: 9098 9099 - TCP: Correct failures in long Telnet sessions by increasing th 9100 size of the number of bytes sent from uint16_t to uint32_t. This 9101 avoids an integer overflow that causes a long Telnet session to be 9102 closed unexpectedly. From Rony XLN. 9103 - Network locks: Correct some network lock logic: Two error 9104 conditions where the network was not being unlocked and one where it 9105 was getting unlocked twice. From Jussi Kivilinna. 9106 - Local Sockets: Local stream sockets had problem of double releasing 9107 pipes (both server and client attempt release), which causes wrong 9108 pipe pair being closed in multi-client case. Solve by adding per 9109 connection instance ID to pipe names. From Jussi Kivilinna. 9110 - TCP: Fix an important TCP networking bug: 16-bit flags was being 9111 converted to 8-bits in a few locations, causing loss of status 9112 indications. 9113 - TCP: net_startmonitor() always returned OK. In the race case 9114 where a socket has already been closed, it correctly handled the 9115 disconnection event but still returned OK. Returning OK caused the 9116 callers of net_startmonitor() to assume that the connection was 9117 okay, undoing the good things that net_startmonitor() did and 9118 causing the socket to be incorrectly marked as connected. This 9119 behavior was noted by Pelle Windestam. 9120 - setsockopt() failed when setting timeouts to values less tha 100 9121 msec. That is because the timeout is limited to stops of 1 9122 decisecond and because the conversion of structure timeval was 9123 truncating the microsecond remainder. The utility 9124 net_timeval2dsec() now accepts and option to determine how it 9125 handles the remainder: truncate, discarding the remainder, use 9126 the remainder to round to the closed decisecond value, or use any 9127 non-zero remainder to the next larger whole decisecond value. Bug 9128 discovered by Librae. 9129 - TCP: In the TCP connection operation, it was trying to setup the 9130 network monitor BEFORE the socket was successfully connected. This, 9131 of course, has ALWAYS failed because the socket is not yet connected 9132 and the TCP state is not yet correct for a connected socket. However, 9133 because of other changes net_startmonitor() now returns a failure 9134 condition that causes worse problems when trying to connect. The fix 9135 is to move the logic that starts the network monitor to AFTER the 9136 socket has been successfully connected. 9137 9138 * Atmel SAM3/4 Drivers: 9139 9140 - SAM4CM and SAMA5D Free-running timer: Logic that samples the free 9141 running counter reads the pending interrupt status register and can 9142 cause interrupts to be lost. So, if when the status register is 9143 read, the logic must also handle the timer overflow event. Found 9144 and fixed by Max Neklyudov. 9145 9146 * Atmel SAMA5 Drivers: 9147 9148 - SAM3/4 Serial: When reconfigured, serial does not receive bytes 9149 from UART. This happens because RX interrupt was disabled in the 9150 setup routine. Fixed this I save interrupt configuration before 9151 UART shutdown and restore it after. From Max Neklyudov. 9152 9153 * NXP LPC17xx Drivers: 9154 9155 - LPC176x GPIO: Reorder steps when an output GPIO is configured in 9156 order to avoid transient bad values from being output. From Hal 9157 Glenn. 9158 - LPC17 USB OHCI: Correct some initialization of data structures. 9159 When hub support is enabled, it would overwrite the end of an array 9160 and clobber some OS data structures. 9161 - LPC17xx Ethernet: Review, update, and modify the Ethernet driver so 9162 that it works better with CONFIG_NET_NOINTS=y. Also, update all 9163 LPC17xx networking configurations so that they have 9164 CONFIG_NET_NOTINTS=y selected. 9165 9166 * SiLabs EMF32 Drivers: 9167 9168 - EFM32 SPI: Add missing SPI GPIO pin initialization. From Pierre-noel 9169 Bouteville. 9170 9171 * STMicro STM32: 9172 9173 - STM32 F3: Added missing EXTI definitions for the STM32 F3; Correct 9174 an error the port D base address in the STM32 F30x and F37x memory 9175 maps. From Greg Meiste. 9176 9177 * STMicro STM32 Drivers: 9178 9179 - STM23 RTC: Fix an error introduced into stm32_pwr_enablebkp(). 9180 That function must preserve the previous state of backup domain 9181 access on return. 9182 - STM32 RTC counter: Now need to enable backup domain write access 9183 when setting the time. From Darcy Gong. 9184 - STM32 OTG FS and HS: Added protection in the event that out-of-bound 9185 endpoint numbers are received. From David Sidrane. 9186 9187 * STMicro STM32 Boards: 9188 9189 - STM32F429i Disco: (1) Fix a bad return value if the LCD driver is 9190 already initialized. (2) The LCD driver initialization is now 9191 performed during the early boot sequence. (3) Increased the size 9192 of the message queue from 32 to 64 in the lcd configuration. From 9193 Marco Krahl. 9194 9195 * TI Tiva 9196 9197 - Fixes for Tiva TM4C1294NCPDT. From Frank Sautter. 9198 9199 * Atmel SAMV71 Drivers: 9200 9201 - SAMV7 TWIHS: Fix SAMV TWIHS logic that performs multi-message 9202 transfers with and without repeated starts. 9203 9204 * Atmel SAMA5D3/4 Dirvers: 9205 9206 - SAMA5 CAN: Fix SAMA5 CAN frame construction. From Max Holtzberg. 9207 9208 * C Library/Header Files: 9209 9210 - stdlib.h: MAX_RAND should be RAND_MAX. 9211 - assert.h: Wrap definitions of assertion macros in do while so that 9212 they are valid C statements. Numerous places throughout the code 9213 where semicolons were missing at the end of an assertion also had to 9214 be fixed. Suggested by orbitalfox. 9215 - inetntoa(): Correct errors in printing IP address when type char is 9216 signed and the value is >= 128.

Needed 9371 for backward compatible support for Teensy-3.0. 9372 9373 * Freescale (NXP) Kinetis Boards: 9374 9375 - Teensy 3.x: Add board support for the PJRC Teensy-3.0 and 9376 Teensy-3.1 boards. 9377 9378 * Atmel SAMV7 Drivers: 9379 9380 - SAMV7: Add an MCAN driver for the SAMV7 platform. 9381 - SAMV7 SPI Slave Driver: Add the an SPI slave driver. 9382 9383 * STMicro STM32: 9384 9385 - STMicro STM32 F7: Add architecture support for the STMicro STM32 9386 F7. 9387 - STM32 F446: Add support for the STMicro STM32 F446. From David 9388 Sidrane. 9389 9390 * STMicro STM32 Drivers: 9391 9392 - STM32 F7: Add an STM32 F7 Ethernet driver. 9393 - STM32 F7: Port the STM32 F4 DMA driver. 9394 - STM32 F4 ADC: Add DMA support to the ADC driver for STM32 F4. From 9395 Max Kriegler. 9396 9397 * STMicro STM32 Boards: 9398 9399 - STM32F762G-Disco: Add support for the STMicro STM32 F7 Discovery 9400 board. 9401 - STM32F4-Disco: Add support to BMP180 driver on the STM32F4 Discovery. 9402 From Alan Carvalho de Assis. 9403 9404 * C Library/Header Files: 9405 9406 - Add asctime(), asctime_r(), ctime(), and ctime_r(). 9407 - sethostname(): Add support for sethostname(). 9408 - gethostbyname() and gethostbyaddr(): Add support for 9409 gethostbyname() and gethostbyaddr(). Also support included for the 9410 non-standard gethostbyname_r() and gethostbyaddr_r(). This moves 9411 the DNS client logic from apps/ into the NuttX libc implementation. 9412 9413 * Tools: 9414 9415 - testbuild.sh: Add a script that can be used to perform building 9416 testing for several board configurations. 9417 9418 * Build/Configuration System: 9419 9420 - apps/ Build System: No longer depends on hardcoded lists of 9421 directories. Instead, it does a wildcard search to find all 9422 appropriate directories. This means that to install a new 9423 application, you simply have to copy the directory (or link it) into 9424 the apps/ directory. If the new directory includes a Makefile and 9425 Make.defs file, then it will automatically be included in the build. 9426 - mkkonfig.sh: Add the tool mkkconfig.sh that dynamically builds the 9427 apps/Kconfig file at configuration time. The hardcoded 9428 configuration file has been removed and now the top-level Makefile 9429 executes tools/mkkconfig.sh to auto-generate the top-level Kconfig 9430 file. A new apps/ make target call preconfig: was added to support 9431 this operation. Now you do not have to modify the top-level Kconfig 9432 file to add a new directory into the configuration; the top-level 9433 subdirectory simply needs to include a Kconfig file and it will 9434 automatically be included in the configuration. The native Windows 9435 build is temporarily broken until a new apps/tools/mkconfig.bat 9436 script is generated. 9437 - mkkconfig.bat: Add the Windows script corresponding to 9438 apps/tools/mkkconfig.sh. Needed for a Windows native build. 9439 9440 * Applications: apps/nshlib: 9441 9442 - NSH shutdown command: NSH will now support an (optional) shutdown 9443 command if the board provides the option CONFIG_BOARDCTL_POWEROFF. 9444 The command can also be used to reset the system if 9445 CONFIG_BOARDCTL_RESET=y. 9446 - NSH uname command: Add support for a uname command. 9447 - NSH nslookup command: Add an nslookup command. 9448 9449 * Applications: apps/system: 9450 9451 - NetDB: Add a system command to access the network database. 9452 - readline(): Add support for Unix-style tab complete to readline. 9453 Contributed by Nghia Ho. 9454 - readline(): Extended the tab-completion support to also expand NSH 9455 command names. 9456 - readline(): Add support for an in-memory command line history that 9457 can be retrieved using the up and down arrows. Contributed by Nghia 9458 Ho. 9459 9460 * Applications: apps/netutils: 9461 9462 - DNS client: Moved the DNS client logic into the NuttX C library. 9463 It is a necessary part for the full implementation of the netdb logic 9464 and provides more flexibility in that location. 9465 - Replace calls to the non-standard dns_gethotip() with calls to 9466 standard gethostbyname(). 9467 - NetLib: Create netlib wrapper functions around dns_getserver() and 9468 dns_setserver() to isolate application code from changes to those 9469 interfaces. 9470 9471 * Applications: apps/examples: 9472 9473 - OS test: Extend the OS test to include a test of 9474 pthread_mutex_trylock() for recursive mutexes. From Juha Niskanen. 9475 - OS test: Add a test for the sporadic scheduler. 9476 9477Bugfixes. Only the most critical bugfixes are listed here (see the 9478ChangeLog for the complete list of bugfixes and for additional, more 9479detailed bugfix information): 9480 9481 * Core OS: 9482 9483 - pthreads: Use -1 instead of 0 as PID for unclaimed mutexes. From 9484 Juha Niskanen. 9485 - pthreads: Implement pthread_mutex_trylock() for recursive mutexes. 9486 From Juha Niskanen. 9487 - pthread_create(): Group binding needs to be cleared before 9488 sched_releasetcb(), as otherwise group_leave() will be called and 9489 group->tg_nmembers decremented or group being released. group_leave() 9490 should be called only after group_join() is called, not after 9491 group_bind(). From Jussi Kivilinna. 9492 - Protected Mode User Memory Allocator: Redesigned how the user space 9493 heap is accessed from the kernel code in protected mode. It used to 9494 call memory management functions in user space via function pointers 9495 in the userspace interface. That is inefficient because the first 9496 thing that those memory management functions do is to trap back into 9497 the kernel to get the current PID. Worse, that operation can be 9498 fatal is certain fragile situations such as when a task is exiting. 9499 The solution is to remove all of the memory management function 9500 calls from the interface. Instead, the interface exports the users 9501 pace heap structure and then kernel size implementations of those 9502 memory management functions will operate on the userspace heap 9503 structure. This avoids the unnecessary system calls and, more 9504 importantly, failures do to freeing memory when a test exits. 9505 - pthread_create(): Fix an (unlikely) error in fallback value in the 9506 event of a failure (which should never occur). 9507 9508 * Common Drivers: 9509 9510 - STMPE811 Driver: In stmpe811_instanciate() when 9511 CONFIG_STMPE811_MULTIPLE is enabled, and the call to 9512 stmpe811_checkid() fails, then the linked device list is not 9513 restored to its previous state. From Sebastien Lorquet. 9514 - CAN driver: Fix an issue in the CAN driver where the rx_sem count 9515 can grow beyond bounds. 9516 9517 * File System/Block Drivers: 9518 9519 - NFS client: Fix prototype of unbind method. The function prototype 9520 was not updated for NFS after a recent change to the file system 9521 interface. From Manuel St??. 9522 9523 * Networking/Network Drivers: 9524 9525 - netconfig.h: Fix some backward compilation that was emitting #error 9526 in the wrong condition when SLIP was enabled. 9527 - SLIP Driver: Fix a missed name change when many of network 9528 interface names changed sometime back but were apparently never 9529 updated for SLIP. 9530 - Networking: Allow receipt of empty UDP packets. From Max Neklyudov. 9531 9532 * ARMv6-M: 9533 9534 - ARMv6-M: Fix Cortex-M0 assembly error when the interrupt stack is 9535 enabled. From Alan Carvalho de Assis. 9536 9537 * Atmel SAMD/L Drivers: 9538 9539 - SAMD20, D21, L21: In the SAML21, SERCOM5 uses a different SLOW clock 9540 channel (and, hence, also a different SLOW GCLK generator). This 9541 means that the channel selection cannot be a global definition but 9542 must be a per SERCOM configuration setting. 9543 - SAMD/L: Several fixes to register definitions and types. From 9544 Janne Rosberg. 9545 9546 * Atmel SAM3/4 Drivers: 9547 9548 - SAM3/4 UART: Back out an error introduced with commit 9549 02c33f66c5a8be774034cd40e4125e9323c7b4d8. Causes an infinite loop in 9550 up_lowputc(). From Max Neklyudov. 9551 - SAM4CM: Fix SUPC register definitions. From Max Neklyudov. 9552 - SAM3/4 WDT: Correct some problems with SAM3/4 watchdog driver. 9553 Includes some small improvements. From Max Neklyudov. 9554 9555 * Atmel SAMV7 Drivers: 9556 9557 - SAMV7 UART: Also back the bad cloned change o sam_lowputc.c for 9558 SAMV7 platform. 9559 9560 * NXP LPC43xx Drivers: 9561 9562 - LPC4350: Correct some LPC4350 GPIO pin configurations. From 9563 Alessandro Temil. 9564 9565 * SiLabs EMF32 Drivers: 9566 9567 - EFM32 SPI: Correct write to incorrect register in EFM32 SPI driver. 9568 From Pierre-noel Bouteville. 9569 9570 * STMicro STM32 Drivers: 9571 9572 - STM32 F15x: STM322 F15x stm32_stdclockconfig() was calling 9573 stm32_pw_setvos() which accessed PWR_CR via an inactive APB From 9574 Juha Niskaneni. 9575 - STM32 Ethernet: Extend STM32 Ethernet operating frequency to 180MHz. 9576 From Sebastien Lorquet. 9577 9578 * STMicro STM32 Boards: 9579 9580 - SAMV7 Xplained: In clock configuration, divider was set to 25 to get 9581 25*12MHz=300MHz CPU clock. The correct multiplier is 24 because the 9582 calculation if (24+1)*12MHz. So the board was running at 312MHz. 9583 From Efim Monjak. 9584 9585 * ARMv7-A: 9586 9587 - Cortex-A5 vfork(): Fix a Cortex-A compilation error when system 9588 calls are enabled in modes other than CONFIG_BUILD_KERNEL. 9589 9590 * Atmel SAMA5 Drivers: 9591 9592 - SAMA5Dx EHCI: Fix some bad conditional compilation that left a 9593 function undefined if CONFIG_USBHOST_ASYNCH is not selected. 9594 9595 * C Library/Header Files: 9596 9597 - getopt(): Uninitialized variable can cause hardfault from getopt() 9598 if required argument is missing. From George McWilliams. 9599 9600 * Applications: apps/nshlib: 9601 9602 - NSH/THHPD: Change decoding to handle the increased size of the 9603 scheduling policy field in the TCB. 9604 9605 * Applications: apps/netutils: 9606 9607 - THTTPD: Fix compilation problems when 9608 CONFIG_THTTPD_GENERATE_INDICES is defined. 9609 - THTTPD: Missing gci-src as a dependency path when building with 9610 BINFS enabled. 9611 9612 * Applications: apps/examples: 9613 9614 - poll() example: Fix a few bit-rot compilation errors. 9615 - Nx Lines example: If CONFIG_NX_ANTIALIASING=y, then the nxlines 9616 example now erases a line that is 2 pixels longer and 2 pixels wider 9617 than the line it drew. That eliminates edges effects due to 9618 applying the anti-aliasing algorithm twice. A better solution 9619 would be to make anti-aliasing an option for each graphics call so 9620 you would rend the line with anti-aliasing ON and clear it with 9621 anti-aliasing OFF. but I don't have the wherewithal for that change 9622 today. 9623 - OS test: Improve synchronization in round robin tests. On very fast 9624 processors, there are race conditions that make the test fail. 9625 Need better interlocking to assure that the threads actually do start 9626 at the same time. 9627 9628NuttX-7.12 Release Notes 9629------------------------ 9630 9631The 112th release of NuttX, Version 7.12, was made on October 1, 2015, 9632and is available for download from the Bitbucket.org website. Note 9633that release consists of two tarballs: nuttx-7.12.tar.gz and 9634apps-7.12.tar.gz. These are available from: 9635 9636 https://bitbucket.org/patacongo/nuttx/downloads 9637 https://bitbucket.org/nuttx/apps/downloads 9638 9639Both may be needed (see the top-level nuttx/README.txt file for build 9640information). 9641 9642Additional new features and extended functionality: 9643 9644 * Graphics/Graphic Drivers: 9645 9646 - Added SSD1351 OLED controller support. Contributed by Paul 9647 Alexander Patience. 9648 9649 * Common Device Drivers: 9650 9651 - MS58xx: Generalize the MS5805 altimeter driver to support other 9652 family members. From Paul Alexander Patience. 9653 - CAN driver interface: Add an error indication bit to the CAN 9654 message report. 9655 - Developed a new interface for QSPI. Most QSPI hardware (such as the 9656 SAMV71) used a programmed interface to access the QuadSPI FLASH. 9657 That programmed interface is no compatible with the simpler NuttX 9658 SPI data transfer interface. 9659 - Added a driver for ST25L1*K QuadSPI parts. 9660 - Renamed the battery driver interface to battery_gauge since it 9661 really only implements a battery fuel gauge. From Alan Carvalho de 9662 Assis. 9663 - Added a new framework to support a batter charger interface. From 9664 Alan Carvalho de Assis. 9665 - Added a BQ24250 battery charger driver.

Modern Cygwin X86_64 9677 machines follow the Microsoft ABI for parameter passing. The Linux 9678 System 5 ABI would not work on X86_64-based Cygwin machines. Newer 9679 Cygwin tool chains do nor pre-pend symbol names with the underscore 9680 character. 9681 9682 * Atmel SAMA5Dx: 9683 9684 - Added architectural support for the Atmel SAMA5D2 parts. Not fully 9685 verified in this NuttX release. 9686 9687 * Atmel SAMA5Dx Boards: 9688 9689 - Added support for the Atmel SAMA45D2 Xplained Ultra board. Not 9690 fully verified in this NuttX release. 9691 9692 * Atmel SAMV7 Drivers: 9693 9694 - SAMV7 USBHS DCD: The device controller driver is (finally) 9695 functional. 9696 9697 * NXP LPC17xx: 9698 9699 - Implement options to use external SDRAM and or SRAM for the heap. 9700 From Pavel Pisa. 9701 9702 * NXP LPC43x: 9703 9704 - Added architectural support for the LPC4370. From Lok Tep. 9705 9706 * NXP LPC43xx Drivers: 9707 9708 - Added Ethernet support.

From Paul 9720 Alexander Patience. 9721 9722 * STMicro STM32 Drivers: 9723 9724 - Added OTG support for STM32F44x. From David Sidrane. 9725 9726 * STMicro STM32 Boards: 9727 9728 - Added support for the STMicro Nucleo F303ERE board from Paul 9729 Alexander Patience. 9730 9731 * C Library/Header Files: 9732 9733 - stdlib: Add support for div() to the C library. From OrbitalFox. 9734 Also added ldiv() and lldiv() which are equivalent to div() with 9735 long and long long types, respectively, instead of int. 9736 - Added an implementation of the standard shutdown function. 9737 9738 * Tools: 9739 9740 - tools/mksymtab: declare g_symtab array as const to occupy RO section 9741 (Flash). From Pavel Pisa. 9742 9743 * Build/Configuration System: 9744 9745 - Simplify configs/ Makefiles by combining common logic into a new 9746 Board.mk Makefile fragment. From Paul Alexander Patience. 9747 9748 * Applications: apps/system: 9749 9750 - apps/system/symtab: Optional canned symtab inclusion to the build. 9751 When option CONFIG_SYSTEM_SYMTAB is selected and symbol table file 9752 libc/symtab/canned_symtab.inc is prepared then application can use 9753 system provided complete symbol table. The option has substantial 9754 effect on system image size. Mainly code/text. If loading of 9755 applications at runtime is not planned do not select this. From 9756 Pavel Pisa. 9757 9758 * Applications: apps/canutils: 9759 9760 - apps/canutils/uavcan: Add support for libuavcan. From Paul Alexander Patience. 9761 9762 * Applications: apps/examples: 9763 9764 - apps/examples/can: Extend the CAN loopback test by adding more 9765 command line options. 9766 - apps/examples/usbserial: Can now be run as an NSH builtin-function. 9767 Now uses a configurable IO buffer size. 9768 - apps/examples/nettest: Add option to suppress network initialization. 9769 This is necessary if the nettest is run from NSH which has already 9770 initialized the network. 9771 - apps/examples/nettest: Extend test so that can be performed using 9772 the local loopback device. 9773 - apps/examples/netloop: Add a test of the local loopback device. 9774 - apps/examples/udpblaster: Add a test to stress the network by 9775 sending UDP packets at a very high rate. . 9776 - apps/examples/uavcan: libuavcan example from Paul Alexander Patience. 9777 9778Bugfixes. Only the most critical bugfixes are listed here (see the 9779ChangeLog for the complete list of bugfixes and for additional, more 9780detailed bugfix information): 9781 9782 * Core OS: 9783 9784 - wd_create(): Correct a counting error in the number of available 9785 watchdog timers. When the number of free timers is low, the counter 9786 could be incremented below zero. 9787 - mq_open(): When message queue is opened, inode_reserve() leaves the 9788 reference count at zero. mq_open() logic must assure that the 9789 reference count of the newly created inode is one. 9790 - work_queue(): Logic that sets the queued indication and the logic 9791 that does the actual queuing must be atomic. 9792 9793 * Binary Loader: 9794 9795 - Fix a memory leak in the built-in application logic: File was not 9796 being closed. From Bruno Herrera. 9797 9798 * File System/Block Drivers: 9799 9800 - poll(): If we fail to setup the poll for any file descriptor, for 9801 any reason, set the POLLERR bit. 9802 - rwbuffer: Fix some logic errors. From Dmitry Nikolaev via Juha 9803 Niskanen. 9804 - ROMFS: One allocation was not being freed if there was a subsequent 9805 failure to allocation I/O buffers resulting in a memory leak on 9806 certain error conditions. From Bruno Herrera. 9807 9808 * Networking/Network Drivers: 9809 9810 - Fix a bug in tun interface driver. From Max Neklyudov. 9811 - recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is 9812 enabled. Fix size accounting when recvfrom_udpreadahead() sets 9813 state.rf_recvlen == -1. I have not checked if data are accumulated 9814 to the right position in the buffer however. From Pavel Pisa. 9815 - networking: Correct return value from psock_tcp_accept(). From 9816 SaeHie Park. 9817 - TCP: Fix a problem in when there are multiple network devices. 9818 Polls were being sent to all TCP sockets before. This is not good 9819 because it means that packets may sometimes be sent out on the wrong 9820 device. That is inefficient because it will cause retransmissions 9821 and bad performance. But, worse, when one of the devices is not 9822 Ethernet, it will have a different MSS and, as a result, incorrect 9823 data transfers can cause crashes. The fix is to lock into a single 9824 device once the MSS is locked locked down. 9825 - net/tcp: The logic that binds a specific network device to a 9826 connection was faulty for the case of multiple network devices. On 9827 bind(), the local address should be used to associate a device with 9828 the connection (if the local address is not INADDR_ANY); On connect(), 9829 the remote address should be used (in case the local address is 9830 INADDR_ANY). On accept(), it does not matter but the remote address 9831 is the one guaranteed to be available. 9832 - net/tcp: Fix unbuffered send compilation error when Ethernet is not 9833 enabled. From Alan Cavalho de Assis. 9834 9835 * ARMv7-M: 9836 9837 - All ARMV7-M IRQ setup: Always set the NVIC vector table address 9838 unconditionally. This is needed in cases where the code is running 9839 with a bootload and when the code is running from RAM. It is also 9840 needed by the logic of up_ramvec_initialize() which gets the vector 9841 base address from the NVIC. Suggested by Pavel Pisa. 9842 - Fix some H/W floating point logic: In the original implementation, 9843 !defined(CONFIG_ARMV7M_CMNVECTOR) was a sufficient test to determine 9844 if lazy floating point register saving was being used. But recents 9845 changes added common lazy register as well so now that test must be 9846 (!defined(CONFIG_ARMV7M_CMNVECTOR) || defined(CONFIG_ARMV7M_LAZYFPU)). 9847 - ARMv7-M, all "lazy" interrupt stack logic. Assembly instruction 9848 that fetches the saved value is incorrect; replace with more 9849 traditional push and pop. This is an important fix. Noted by 9850 Stefan Kolb. 9851 - All ARMV7-M: Force 8-byte stack alignment when calling from assembly 9852 to C to interrupt handling. 9853 - up_schedulesigaction(): Fix logic that determines if there is a 9854 pending signal action before scheduling the next signal action. 9855 Both the test and the scheduling action need to be atomic. This 9856 problem was fixed on the ARMv7-M but also ported to other 9857 architectures that had the same issue. 9858 9859 * NXP LPC43xx: 9860 9861 - LPC43xx: Fix NVIC_SYSH_PRIORITY_STEP define. From Ilya Averyanov. 9862 - LPC43xx: Fix missing #define in eeprom. From Ilya Averyanov. 9863 9864 * NXP LPC43xx Drivers: 9865 9866 - Fixed the SPI driver. From Ilya Averyanov. 9867 9868 * Atmel SAMA5 Drivers: 9869 9870 - LPC31 and SAMA5D EHCI: Fix qh_ioccheck to move bp to next QH. From 9871 Ilya Averyanov. 9872 - LPC31 and SAMA5D EHCI: Performance improvement: Do not disable the 9873 asynchronous queue when adding a new QH structure. From Ilya 9874 Averyanov. 9875 9876 * C Library/Header Files: 9877 9878 - gethostbyname(): correct returned address format when DNS is used. 9879 The hostent.h_addr_list should point to raw in_addr or in6_addr 9880 as defined in the standard. Original implementation used that for 9881 numeric addresses but for DNS lookup returned pointer to whole 9882 sockaddr_in or sockaddr_in6. From Pavel Pisa . 9883 - asin(): The function did not convert for some input values. asing() 9884 did not convert for values which do not belong to the domain of the 9885 function. But aside of that the function also did not converge for 9886 allowed values. I achieved a conversion of the function by 9887 reducing the DBL_EPSION and by checking if the input value is in 9888 the domain of the function. This is a fix for the problem but the 9889 function should always terminate after a given number of iterations. 9890 From Stefan Kolb. 9891 - Change all references from avsprintf to vasprintf. From Sebastien 9892 Lorquet. 9893 9894 * Applications: apps/nshlib: 9895 9896 - Fix error handling in 'cat' command. On a failure to allocate 9897 memory, a file was not being closed. From Bruno Herrera. 9898 - Fix error handling in 'mv' command. On a failure to expand the 9899 second path, the memory allocated for the expansion of the first 9900 path was not being freed. From Bruno Herrera. 9901 9902 * Applications: apps/system: 9903 9904 - apps/system/netdb: Failed to build if CONFIG_NET_HOSTFILE was not 9905 defined because gethostbyaddr() was not available. Noted by 9906 OrbitalFox. 9907 9908 * Applications: apps/netutils: 9909 9910 - Various Kconfig files in netutils: Fix some changes from from 9911 NETUTILS_DNSCLIENT to NETDB_DNSCLIENT. From Pavel Pisa. 9912 9913 * Applications: apps/modbus: 9914 9915 - Macros PR_BEGIN_EXTERN_C and PR_END_EXTERN_C were not defined in 9916 all contexts. Replace with explicit expansion in all cases. From Stefan Kolb. 9917 9918NuttX-7.13 Release Notes 9919------------------------ 9920 9921The 113th release of NuttX, Version 7.13, was made on December 5, 2015, 9922and is available for download from the Bitbucket.org website. Note 9923that release consists of two tarballs: nuttx-7.13.tar.gz and 9924apps-7.13.tar.gz. These are available from: 9925 9926 https://bitbucket.org/patacongo/nuttx/downloads 9927 https://bitbucket.org/nuttx/apps/downloads 9928 9929Both may be needed (see the top-level nuttx/README.txt file for build 9930information). 9931 9932Additional new features and extended functionality: 9933 9934 * Core OS: 9935 9936 - External RTC: Added OS support for external RTC chips. 9937 - boardctl(): Add a command to the boardctl() interface to obtain a 9938 board unique ID. 9939 9940 * File Systems: 9941 9942 - TMPFS: Add support for a new TMPFS, RAM file system. The TMPFS 9943 file system does not require any significant amount of memory 9944 itself. It will grow dynamically as files are added and shrink back 9945 when files are deleted. A very low overhead way to retain temporary 9946 files. 9947 - VFS: The VFS was extended to support standard file operations on 9948 block drivers (open, close, read, write, etc.). The open() interface 9949 accomplishes this by creating a temporary characer driver to mediate 9950 the character oriented accesses to tje block driver. 9951 - HOSTFS: Added a HOSTFS file system for use with the simulator. The 9952 HOSTFS file system mounts in the simulated Nuttx context by provides 9953 proxied access to the file system on the host PC. This is useful for 9954 providing file system content and nonvolatile storage of files in the 9955 simulation environment. From Ken Pettit. 9956 - MTD/PROCFS: Add an interface to un-register an MTD procfs entry. 9957 From Ken Pettit. 9958 - filemtd: A new MTD conversion layer that will convert a regular file 9959 (or driver file) to an MTD device. This is useful for testing on the 9960 simulation using the HOSTFS. From Ken Pettit. 9961 - PROCFS: Extended to include networking entries in the procfs. Device 9962 status, device statistics, and network statistics are now available 9963 from the PROCFS. 9964 - PROCFS: The PROCFS file system can now be configured so that it 9965 supports runtime registration of PROCFS entries with 9966 CONFIG_FS_PROCFS_REGISTER=y. 9967 9968 * Graphics/Graphic Drivers: 9969 9970 - ST7565 Driver: Extend to include support for the ERC12864-3. From 9971 Pierre-noel Bouteville. 9972 9973 * Common Device Drivers: 9974 9975 - User buttons: Added a character driver to support application access 9976 to board buttons. Supports notification of button activity via 9977 signals. 9978 - User LEDs: Added a character driver to support application access 9979 to on-board LEDs. 9980 - Zero Cross: Added a Zero Cross device driver support. From Alan 9981 Carvalho de Assis. 9982 - MAX6675: Added support to Thermocouple-to-Digital converter MAX6675. 9983 From Alan Carvalho de Assis. 9984 - BCH: Block-to-character (BCH) driver should forward ioctl() calls 9985 to the contained block driver. 9986 - S25FL1xx: Added a S25FL1xx QuadSPI FLASH driver. 9987 - On-Chip FLASH: Added an upper half MTD device that can use the 9988 interfaces defined in included/nuttx/progmem.h to provide a 9989 standard MTD driver. 9990 - Serial: Implemented high level DMA infrastructure for serial 9991 devices. From Max Neklyudov. 9992 - AT24XX: Add support for multiple AT24xx EEPROM parts, each with 9993 unique I2C addresses, but otherwise identical. 9994 - External RTC: Added drivers for external I2C RTC chips: DS3102, 9995 DS1307, DS3231, DS3232, and NXP PCF85263. 9996 - W25: Added support for byte write mode to the W25 FLASH driver. From 9997 Ken Pettit. 9998 - dev/loop: Added a loop character device. losetup() and loteardown() 9999 should not be called directory from applications. Rather, these 10000 functions are now available as IOCTL commands to the loop driver. 10001 - dev/smart: Added support for a /dev/smart loop device. From Ken 10002 Pettit. 10003 10004 * Networking: 10005 10006 - Driver Statistics: Most network drivers do not support statistics. 10007 Those that do only supported them when DEBUG is enabled. Each 10008 driver collected an architecture specific set of statistics and 10009 there was no common mechanism to view those statistics. Thus, 10010 the driver feature was mostly useless. This release standardizes 10011 the driver statistics and puts the definition in the common network 10012 device structure defined in netdev.h where they can be accessed by 10013 network applications. All Ethernet drivers that collect statistics 10014 have been adapted to use these common statistics. 10015 10016 * Simulation Platform: 10017 10018 - W25 FLASH: Added support for W25 FLASH simulation. From Ken Pettit. 10019 - HOSTFS: Added support for the HOSTFS file system (see "File Systems", 10020 above). 10021 10022 * Atmel SAMV7: 10023 10024 - SAME70: Added support for the SAME70 family of chips. 10025 - Tickless: SAMV7 now supports the tickless mode of operation. 10026 10027 * Atmel SAMV7 Drivers: 10028 10029 - MPU: Added MPU and protected build support. 10030 - QSPI: Added a QuadSPI FLASH driver. This driver operates in the 10031 memory-mapped, Serial Memory Mode (SMM). 10032 - FLASH: Added support to write on-chip FLASH. 10033 - Timer/Counter: TC driver ported to SAMV7 from the SAMA5. Free-running 10034 and one-short timer logic also ported. 10035 - PCK: Brought programmable clock (PCK) logic from SAMA5 into SAMV7. 10036 - Timer/Counter: Support PCK6 as an optional source for the timer/ 10037 counter clock. 10038 10039 * Atmel SAMV7 Boards: 10040 10041 - SAME70-Xplained: Add NSH and networking configurations for the 10042 SAME70 Xplained board. Includes verified support for serial console, 10043 LEDs, buttons, SDRAM, HSMCI SD card, and networking. 10044 - SAMV7-XULT and SAME70-Xplained: If Tickless mode is selected then 10045 enable PCK6 as a timer/counter clock source 10046 10047 * STMicro STM32: 10048 10049 - CCM PROCFS: Is no longer a part of the 'base' procfs entries and can 10050 now only be supported via run time registration with 10051 CONFIG_FS_PROCFS_REGISTER=y. 10052 10053 * STMicro STM32 Drivers: 10054 10055 - Timers: Add a compatible lower-half timer driver for use with the 10056 common timer upper-half driver. From Wail Khemir. 10057 10058 * STMicro STM32 Boards: 10059 10060 - STM32F4-Discovery: Add low level support for the Zero Cross driver 10061 for the STM32F4-Discovery. From Alan Carvalho de Assis. 10062 - STM32F4-Discovery: Add board config to support for the MAX6675. From 10063 Alan Carvalho de Assis. 10064 10065 * C Library/Header Files: 10066 10067 - bsearch(): Added the bsearch() function from NetBSD. 10068 - freopen(): Added support for freopen(). 10069 - strftime(): Added day-of-week support (when avaialable). 10070 10071 * Tools: 10072 10073 - nxstyle: Add crappy style checking tool nxstyle.c. See thee tools/ 10074 README file for more info. 10075 10076 * Applications: NSH 10077 10078 - mksmartfs command: Add configuration option to supported multiple 10079 rootdirectories. From Ken Pettit. 10080 - Add support for 'basename' and 'dirname' commands. 10081 - set command: Like bash, NSH set command now strips off any leading 10082 or trailing whitespace. 10083 - mount command: The mount commands now accepts mount options 10084 (currently needed only for the hostfs file system). From Ken 10085 Pettit. 10086 - losetup command: NSH no longer calls losetup() and loteardown 10087 directly. Now it opens /dev/loop and accomplishes these things 10088 using ioctl() calls. 10089 - ifconfig command: If CONFIG_NETDEV_STATISTICS=y, then print the 10090 network driver statistics in the ifconfig. 10091 - ifconfig, ifup, and ifdown: These commands now uses /proc/net/<dev> 10092 to view network device configuration and status and /proc/net/stat 10093 to show network statistics. A consequence of this is that you 10094 cannot view this network information if the procfs is not enabled 10095 and mounted at /proc. 10096 - losmart command: Added a new NSH losmart command. losmart setups 10097 up a loop device for the smart MTD driver similar to losetup but 10098 with different syntax. From Ken Pettit. 10099 - ps command: The 'ps' command now uses /proc/<pid>/ to obtain task 10100 status information. A consequence of this is that you cannot use 10101 the 'ps' command if the procfs is not enabled and mounted at /proc. 10102 10103 * Applications: apps/system: 10104 10105 - apps/system/hexed: Port the hexed command line hexadeciamal editor 10106 to Nuttx. See http://apps.venomdev.net/hexed/. 10107 10108 * Applications: apps/fsutils: 10109 10110 - apps/fsutils/smartfs: Move into apps/fsutils from kernel, now uses 10111 only open and ioctl. From Ken Pettit. 10112 10113 * Applications: apps/examples: 10114 10115 - apps/examples/fstest: Add a generic file system test. This is 10116 essentially the same as examples/smart, but has all of the SmartFS 10117 specific logic ripped out. This was created for testing the new 10118 TMPFS. 10119 - apps/examples/zerocross: Add a Zero Cross application example. From 10120 Alan Carvalho de Assis. 10121 - apps/examples/media: Add a simple test for access of media via a 10122 block driver or MTD driver. 10123 10124Bugfixes. Only the most critical bugfixes are listed here (see the 10125ChangeLog for the complete list of bugfixes and for additional, more 10126detailed bugfix information): 10127 10128 * Core OS: 10129 10130 - Fixed an error in clock_timespec_subtract(). Found by Lok. 10131 - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that 10132 of the type of a pthread. Hence, it could be confused as a task. 10133 Found because this was causing a crash when /proc/nnn/cmdline was 10134 printed. 10135 10136 * File System/Block Drivers: 10137 10138 - SMART MTD: Fix some Smart wear-leveling bugs. Fixed SmartFS wear 10139 level error that occurs when the logical sector size is too small to 10140 save all wear level status bytes in a single sector. Logical 10141 sectors 1 and 2 were simply not being allocated and then the 10142 read_sector and write_sector routines were failing. From Ken 10143 Pettit. 10144 10145 * Graphics/Graphic Drivers: 10146 10147 - ILI9432: Fixed errors in orientation. Portrait, RPortrait, and 10148 Landscript should work correly now. They were displayed mirrored. 10149 From Marco Krahl. 10150 10151 * Common Drivers: 10152 10153 - CAN: Fix a problem in the CAN upper-half driver that occurs only 10154 for CAN hardware that support a H/W FIFO of outgoing CAN messages. 10155 In this case, there can be a hang condition if both the H/W and 10156 S/W FIFOs are both full. In that case, there may be no event to 10157 awaken the upper half driver. Add a new (conditional) CAN upper 10158 half interface called can_txready() that can be used by the lower 10159 half driver to avoid this hang condition. 10160 - MS58xx: Fix some issues with initialization and with CRC 10161 calculation. From Karim Keddam. 10162 - W25: Fixed W25 FLASH driver page read/write logic. From Ken Pettit. 10163 10164 * Atmel SAMV7 Drivers: 10165 10166 - USART1 pin configuration: Reconfigure System I/O when using USART1. 10167 From Frank Benkert. 10168 - MCAN: Added a call to can_txready() to the MCAN driver. 10169 10170 * STMicro STM32 Drivers: 10171 10172 - stm32 F4: Fix some TIM12 pin mappings. From Max Kriegleder. 10173 10174 * STMicro STM32 Boards: 10175 10176 - STM32F429i-Disco: Calculated partition boundries based on page 10177 block sizes but mtd_partition() is expecting calculations based on 10178 erase block size. From Alan Carvalho de Assis. 10179 10180 * C Library/Header Files: 10181 10182 - sys/types.h: When building on a 64-bit machine, the size of size_t 10183 should be 64-bits. In general, I believe that sizeof(size_t) should 10184 be the same as sizeof(uinptr_t). mmsize_t should always be 32-bits 10185 in any event. The last change to stddef has been backed out. With 10186 these changes, the simulator builds without errors or warnings an a 10187 64-bit machine. 10188 10189 * Applications: apps/nshlib: 10190 10191 - The I/O buffer, g_iobuffer, should not be a global buffer. That 10192 will not work in an environment where there are multiple NSH 10193 sessions. The I/O buffer must, instead, be a part part of the 10194 session-specific data defined in nsh_console.h. 10195 10196NuttX-7.14 Release Notes 10197------------------------ 10198 10199The 114th release of NuttX, Version 7.14, was made on January 28, 2016, 10200and is available for download from the Bitbucket.org website. Note 10201that release consists of two tarballs: nuttx-7.14.tar.gz and 10202apps-7.14.tar.gz. These are available from: 10203 10204 https://bitbucket.org/patacongo/nuttx/downloads 10205 https://bitbucket.org/nuttx/apps/downloads 10206 10207Both may be needed (see the top-level nuttx/README.txt file for build 10208information). 10209 10210Additional new features and extended functionality: 10211 10212 * Core OS: 10213 10214 - modules: Add support for kernel modules: insmod, rmmod, support 10215 functions. procfs support for user lsmod functioniality. 10216 - SIGEV_THREAD: Add support for the SIGEV_THREAD notification method 10217 in struct sigevent. This initial implementation will only work in 10218 the FLAT build since it utilizes the work queue for signal 10219 callbacks. See the top-level TODO file for additional details. 10220 - 64-Bit Timer: If the 64-bit timer is selected, then use it whenever 10221 clock_systimer() is called rather then chopping the 64-bit timer 10222 down to 32-bits. Add a new type, systime_t to represent the 32- or 10223 64-bit system timer. This eliminates clock_systimer32() and 10224 clock_systime64(); there is now only clock_systimer(). 10225 10226 * Common Device Drivers: 10227 10228 - Telnet Driver: Move the Telnet driver from apps/ to 10229 nuttx/drivers/net. It is a driver a belongs in the OS. Now works 10230 like the loop device: A new interface called telnet_initialize() 10231 registers a telnet session "factory" device at /dev/telnet. Via 10232 ioctl, the factory device can create instances of the telnet 10233 character devices at /dev/telnetN to support Telnet sessions. 10234 - PCA9635PW: Add a driver for the PCA9635PW I2C LED driver IC which 10235 can be used to control the intensity of up to 16 LEDs. From 10236 Alexander Entinger. 10237 - MCP9844: Driver for the MCP9844 I2C digital temperature sensor with 10238 a selectable resolution. From Alexander Entinger. 10239 - PN532: Add driver for the NXP PN532 NFC-chip. From Janne Rosberg 10240 and others at Offcode Ltd. 10241 - LSM9DS1: Add driver for the STMicro LSM9DS1 chip. The LSM9DS1 is a 10242 system-in-package featuring a 3D digital linear acceleration sensor, 10243 a 3D digital angular rate sensor, and a 3D digital magnetic sensor. 10244 From Paul Alexander Patience. 10245 - CAN Interface: Add more extensive error reporting capaibility to 10246 the CAN interface definitions. From Frank Benkert. 10247 - SPI Interface: Add an optional hwfeatures() method to the SPI 10248 interface. 10249 10250 * Simulation Platform: 10251 10252 - NSH configuration uses the custom start up scriptwith a read-only 10253 passwd file.

From Dimitry Kloper. 10263 - debug.h: Add an AVR-specific header file used when the AVR MEMX 10264 pointer is used. From Dimitri Kloper. 10265 10266 * Atmel AVR Boards: 10267 10268 - Arduino-Mega2560: Add support for the Arduino-Mega2560. From 10269 Dimitry Koper. 10270 10271 * Atmel SAMV7 Drivers: 10272 10273 - Port the TRNG driver from the SAMA5D3/4 to the SAMV7. 10274 - Port the WDT driver from the SAMA5D3/4 to the SAMV7. 10275 - Add an RSWDT driver. 10276 10277 * Atmel SAMV7 Boards: 10278 10279 - SAMV71-XULT: Add configuration for testing OS modules. 10280 10281 * Freescale Kinetis: 10282 10283 - MK60N512VLL100: Add support for the MK60N512VLL100 Kinetis part. 10284 From Andrew Webster. 10285 10286 * Freescale Kinetis Boards: 10287 10288 - ENET: Numerous updates to the Kinetis ENET driver. That driver is 10289 now functional. From Andrew Webster. 10290 10291 * NXP LPC43xx Boards: 10292 10293 - WaveShare LPC4337-WS: Support for the WaveShare LPC4337-WS board. 10294 From Lok Tep. 10295 10296 * STMicro STM32 Drivers: 10297 10298 - Timer Capture: Add timer input capture driver. From Pierre-Noel 10299 Bouteville. 10300 10301 * STMicro STM32 Boards: 10302 10303 - Olimex STM32 H407: Added a port to the Olimex STM32 H407 board. 10304 This board features the STMicro STM32F407ZGT6 (144 pins). 10305 Contributed by Neil Hancock. 10306 10307 * TI TMS550 Boards: 10308 10309 - TI LaunchXL-TMS57004: Add basic board support for TI LaunchXL- 10310 TMS57004. Still a work in progress. 10311 10312 * C Library/Header Files: 10313 10314 - sys/time.h: Add timeradd(), timersub(), timerclear(), timerisset(), 10315 and timercmp() as macros. These are non-POSIX interfaces, but 10316 included in most BSD deriviatives, including Linux. From Manuel St??. 10317 - AVR support: Introduce support for Atmel toolchain in-flash strings. 10318 Atmel toolchain AVR compiler provides a transparent in-flash object 10319 support using __flash and __memx symbols. The former indicates to 10320 compiler that this is a flash-based object. The later used with 10321 pointer indicates that the referenced object may reside either in 10322 flash or in RAM. The compiler automatically makes 32-bit pointer 10323 with flag indicating whether referenced object is in flash or RAM 10324 and generates code to access either in run-time. Thus, any function 10325 hat accepts __memx object can transparently work with RAM and flash 10326 objects. 10327 For platforms with a Harvard architecture and a very small RAM like 10328 AVR this allows to move all constant strings used in trace messages 10329 to flash in the instruction address space, releasing resources for 10330 other things. This change introduces IOBJ and IPTR type qualifiers. 10331 The 'I' indicates that the object may lie in instruction space on a 10332 Harvard architecture machine. For platforms that do not have __flash 10333 and __memx or similar symbols IOBJ and IPTR are empty, making the 10334 types equivalent to, for example, 'const char' and 'const char*'. 10335 For Atmel compiler these will become 'const __flash char' and 10336 'const __memx char*'. All printf() functions and syslog() functions 10337 are changed so that the qualifier is used with the format parameter. 10338 From Dimitry Kloper. 10339 - debug.h: Add configuration to support an architecture-specific 10340 debug.h header file. From Dimitri Kloper. 10341 - netdb: Add support for the use of a DNS resolver file like 10342 /etc/resolv.conf. 10343 - TEA: Add an implementation of the Tiny Encryption Algorithm. 10344 - math32.h: Add some utilities to support 64-bit arithmetic 10345 operations for platforms that do not support long long types. 10346 10347 * Tools: 10348 10349 - tools/cnvwindeps.c: Add a tool that will convert paths in 10350 dependencies generated by a Windows compiler so that they can be 10351 used with the Cygwin make. 10352 - tools/mkwindeps.sh: A script that coordinates use of cnvwindeps.exe. 10353 Dependencies now work on the Cygwin platform when using a Windows 10354 ative toolchain. 10355 10356 * Applications: NSH 10357 10358 - Module Commands: Add module commands: insmod, rmmod, and lsmod. 10359 - Time Command: Add a 'time' command that may be used to time the 10360 execution of other commands. 10361 - Password Commands: Add useradd, userdel, and passwd commands. 10362 - MOTD: Now supports a Message of the Day (MOTD) that will be 10363 presented after the NSH greeting. 10364 - Session Logins: All sessions may be protected with logins using the 10365 encrypted password in /etc/passwd. 10366 - Extended Logins. Added optional platform-specific function to 10367 perform password verification and optional delay after each failed 10368 login attempt. 10369 10370 * Applications: apps/fsutils: 10371 10372 - apps/fsutils/passwd: Utility library for accessing a password file 10373 like /etc/passwd. 10374 10375 * Applications: apps/netutils: 10376 10377 - apps/netutils/telnetd: Now creates Telnet sessions by opening a new 10378 factory device at /dev/telnet and then using ioctl calls to create 10379 the session character drivers at /dev/telnetN. 10380 - apps/netutils/netlib: Add netlib_get_dripv4addr() and 10381 netlib_get_ipv4netmask(). From Pelle Windestam. 10382 10383 * Applications: apps/examples: 10384 10385 - apps/examples/module: Add a test harness for verifying NuttX kernel 10386 modules. 10387 - apps/examples/pca9635: Add a simple test of PCA9635PW PWM LED driver. 10388 From Alan Carvalho de Assis. 10389 - apps/examples/ostest: Add a test of POSIX timers using SIGEV_THREAD. 10390 10391Bugfixes. Only the most critical bugfixes are listed here (see the 10392ChangeLog for the complete list of bugfixes and for additional, more 10393detailed bugfix information): 10394 10395 * Core OS: 10396 10397 - pthreads: CRITICAL BUGFIX: Logic was wiping out the indication that 10398 of the type of a pthread. Hence, it could be confused as a task. 10399 - waitpid: CRITICAL BUGFIX. Add a reference count to prevent waitpid 10400 from using stale memory released by the waited-for task group. 10401 - clock_systimespec(): Fix an error in a time conversion. 10402 10403 * File System/Block Drivers: 10404 10405 - poll(): Fix handling of sem_tickwait() return value sem_tickwait() 10406 does not return an -1+errno, it returns a negated errno value. 10407 Noted by Freddie Chopin. 10408 10409 * Common Drivers: 10410 10411 - TUN Driver: Fix a compile time error in the TUN driver. From 10412 Vladimir Komendantskiy. 10413 - USB Host HID Parser: Wrong size used in memcpy(). From Hang Xu. 10414 - PCA9555: Fixed a bug in the function pca9555_setbit which occurs if 10415 someone tries to set one of the pins 8-15. The problem is that 10416 after the check if the pin is greater than 7 the variable addr is 10417 incremented and used in the Call I2C_WRITEREAD. But later in the 10418 call to the I2C_WRITE buf[0] is used as address but this address is 10419 not incremented as it should be. Note address does mean the address 10420 to the register in the ioexpander and not the I2C address. From 10421 Stefan Kolb. 10422 10423 * Networking: 10424 10425 - TCP/IOB: Numerous fixes, mostly relate to TCP and IOB buffering 10426 and race conditions. These were necessary for for the NuttX 10427 networking later to be stable in some stress testing. From Andrew 10428 Webster. 10429 10430 * Atmel SAMV7 Drivers: 10431 10432 - USBHS Device: In USBHS device driver, fix check if zero length 10433 packet is needed. 10434 10435 * STMicro STM32 Drivers: 10436 10437 - OTG FS Host: Fix some backward arguments to stm32_putreg(). Note 10438 by Hang Xu. 10439 10440 * Tools: 10441 10442 - tools/mkdeps.c: Extended/fixed support for --winpath option. 10443 Dependencies now work under Cygwin with a native Windows toolchain. 10444 10445 * Build System: 10446 10447 - apps/platform/Makefile: Use a relative path to the board directory 10448 link rather than the absolute path. For Cygwin, the absolute would 10449 would need converted with cygpath. But just using the relative path 10450 is a simpler solution. 10451 10452NuttX-7.15 Release Notes 10453------------------------ 10454 10455The 115th release of NuttX, Version 7.15, was made on March 27, 2016, 10456and is available for download from the Bitbucket.org website. Note 10457that release consists of two tarballs: nuttx-7.15.tar.gz and 10458apps-7.15.tar.gz. These are available from: 10459 10460 https://bitbucket.org/patacongo/nuttx/downloads 10461 https://bitbucket.org/nuttx/apps/downloads 10462 10463Both may be needed (see the top-level nuttx/README.txt file for build 10464information). 10465 10466Additional new features and extended functionality: 10467 10468 * Core OS: 10469 10470 - Add a state variable that provides the current level of OS 10471 initialization. This is needed by some logic that may attempt to 10472 run early in the start-up sequence but cannot run if a sufficient 10473 level of initialization has not yet occurred. 10474 - Spinlocks: Add interface definitions for to support spinlocks as 10475 needed for multi-CPU configurations. 10476 - SMP support. Support for Symmetric Multi-Processing (SMP) added. 10477 This affects many internal data structures, spinlock extensions 10478 and renaming of interrupt enable/disable interfaces, new platform 10479 interfaces to support CPU initialization and inter-actions, and 10480 new application interfaces to manage CPU affinity. The changes 10481 are too extensive to summarize here; see the SMP Wiki page at 10482 http://www.nuttx.org/doku.php?id=wiki:nxinternal:smp. The 10483 new platform interfaces are also described in the NuttX porting 10484 guide: http://www.nuttx.org/doku.php?id=documentation:portingguide. 10485 Only partially verified; awaiting hardware for the complete 10486 verification. 10487 - TLS: Basic definitions needed to support thread local storage 10488 (TLS). TLS is not used anywhere yet (and may not be used in the 10489 near future either). 10490 - Performance Monitoring: Add a configuration option to buffer 10491 RTOS instrumentation data in an in-memory buffer. 10492 - boardctl(): Add boardctl() support that will permit applications 10493 to control USB devices. 10494 10495 * File Systems/Block Drivers: 10496 10497 - procfs: Add /proc/kmm entry that shows that state of the kernel 10498 heap. Only useful in PROTECTED and KERNEL build modes where there 10499 is a kernel heap. 10500 - procfs: Add support for showing CPU in the tast status if SMP is 10501 enabled. 10502 10503 * Networking: 10504 10505 - ARP: Add support for IOCTL commands to manage the ARP table. 10506 - IEEE 802.15.4 and 6LowPAN: There are some radio drivers and a 10507 directory structure is in place. However, most of this 10508 development is occurring on a fork and is not yet available in the 10509 NuttX repositories. Hopefully in NuttX-7.16. 10510 10511 * Common Device Drivers: 10512 10513 - ADS1242: Driver for the 24-Bit Differential Input ADC ADS1242 that 10514 communicates via SPI with a MCU. Reading the ADC conversion result 10515 as well as configuring the ADC, setting the input channel, etc. is 10516 implemented via ioctl calls. However, it does not yet implement 10517 the standard ADC interface. From Alexander Entinger. 10518 - U-Blox Modem: Add an upper half driver for the U-Blox Modem. From 10519 Vladimir Komendantskiy. 10520 - I2C: Add an I2C, "upper half", character drivers to support raw I2C 10521 data transfers for test applications. 10522 - RGB LED: Add a driver to manage a RGB LED via PWM. From Alan 10523 Carvalho de Assis. 10524 - Performance Monitoring: Add a character driver that will allow an 10525 application to read buffered scheduler instrumentation data. 10526 10527 * Simulation Platform: 10528 10529 - SMP: Add multi-CPU support to the simulation to support SMP 10530 investigation. There are issues with the simulation and it is less 10531 than perfect but sufficient for some very preliminary testing of 10532 the core SMP feature. 10533 10534 * ARMv7-A, ARMv7-R, and ARMv7-M: 10535 10536 - ARMv7-A, ARMv7-R, and ARMv7-M: Add test-and-set logic and 10537 definitions needed to supports spinlocks. 10538 - ARMv7-A: Added MPCOre Generic Interrupt Controller (GICv2) and 10539 Global Timer support 10540 - ARMv7-A: Now includes in MCU-specific hooks needed for SMP support. 10541 10542 * Atmel SAMV7 Drivers: 10543 10544 - HSMSI: HSMCI driver can now be configured to handle unaligned data 10545 buffers. 10546 10547 * NXP Freescale LPC11xx/17xx/43xx and LPC2378 Drivers: 10548 10549 - I2C: Backported the LPC43XX I2C driver, replacing the LPC11XX, 10550 LPC17XX, and LPC2378 I2C drivers. This gives us the I2C_TRANSFER 10551 method in all I2C drivers. 10552 10553 * NXP Freescale LPC17xx Boards: 10554 10555 - Support for the u-blox GSM and GPS module evaluation board with 10556 NXP LPCExpresso LPC1768. The GSM module is one of LISA-C200, 10557 LISA-U200 or SARA-G350. The GPS module is one of MAX-M7 or 10558 MAX-M8. From Vladimir Komendantskiy. 10559 10560 * NXP Freescale i.MX6: 10561 10562 - Basic support is in place for the i.MX6 Quad/Dual MCUs. 10563 Verification is, however, waiting for the receipt of hardware. 10564 10565 * NXP Freescale i.MX6 Boards: 10566 10567 - Sabre-6Quad: Basic support for the NXP/Freescale Sabre 6Quad 10568 board is in place but waiting for hardware for verification. 10569 10570 * STMicro STM32: 10571 10572 - STM32F46xx: Support for STM32F46xx from Paul Alexander Patience 10573 - STM32L4: Add support for the STM32L4 family. From Sebastien 10574 Lorquet. 10575 10576 * STMicro STM32 Boards: 10577 10578 - STM32F4 Discovery: Add PWM support for the onboard RGB LED. From 10579 Alan Carvalho de Assis. 10580 - Nucleo-L476: Add support for the Nucleo-L476 board. From Sebastien 10581 Lorquet. 10582 - STM32L476VG Discovery: Add support for the STM32L476VG Discovery 10583 board. From Dave. 10584 10585 * Tools: 10586 10587 - tools/refesh.sh now has a --silent option so that it can be used in 10588 batch modes without human input. 10589 10590 * Build System: 10591 10592 - Added a 'make olddefconfig' target that will refresh a .config file 10593 without interaction. 10594 10595 * Applications: NSH 10596 10597 - 'arp': Add an 'arp' command that will support access to the OS ARP 10598 table. 10599 - 'ps': The 'ps' command will show CPU if SMP is enabled. 10600 10601 * Applications: apps/netutils: 10602 10603 - apps/netutils/chat: Chat logic contributed by Vladimir 10604 Komendantskiy. 10605 - apps/netutils/netlib: Add utility functions to support accesses to 10606 the ARP table. 10607 10608 * Applications: apps/examples: 10609 10610 - apps/examples/chat: Chat example contributed by Vladimir 10611 Komendantskiy. 10612 - apps/sysem/ubloxmodem: Example to control the power 10613 state of the modem in nsh. From Vladimir Komendantskiy. 10614 - apps/examples/leds: An example to demonstrate use of LED driver. 10615 - apps/examples/smp: Add a test to verify SMP configurations. 10616 - apps/examples/rgbled: Example using the RGB LED driver to drive an 10617 RGB LED via PWM. From Alan Carvalho de Assis. 10618 - apps/examples/ostest: Add a test of TLS. 10619 - apps/examples/sched_note: Add a simple example to exercise the 10620 scheduler instrumentation logic. 10621 10622Bugfixes. Only the most critical bugfixes are listed here (see the 10623ChangeLog for the complete list of bugfixes and for additional, more 10624detailed bugfix information): 10625 10626 * Core OS: 10627 10628 - Signals: Move the list of signal actions from the TCB to the group 10629 structure. Signal handlers are not per thread but, rather, per task 10630 group. I know, I preferred it the other way too, but this is more 10631 compliant with POSIX. 10632 - Semaphores: Add an internal, non-standard interface to reset a 10633 semaphore count. This is sometimes needed by drivers in order to 10634 recover from error conditions. Were previously using sem_init() 10635 which is both inappropriate and incorrect if the semaphore count is 10636 negative. 10637 - Low-Priority Work Queue: Fix logic to find an IDLE worker thread; 10638 the test for busy was backward. From Linfei Chen. 10639 10640 * File System/Block Drivers: 10641 10642 - FAT: Add an option to force all transfers to be performed 10643 indirectly using the FAT file system's internal sector buffers. 10644 This is a fix for the case where the user provided buffers are not 10645 properly aligned for DMA (as with THTTPD). 10646 - MTD: Increase block size in mtd_geometry_s to 32-bits. 10647 10648 * Common Drivers: 10649 10650 - I2C: Restructured the I2C interface as necessary to eliminate some 10651 thread-safety issues inherent in the legacy I2C interface design. 10652 This effects the interface definition, all I2C clients, and all low- 10653 level I2C drivers. I have used caution, but I still expect a change 10654 of this magnitude to introduce some errors. Any bug reports of bug 10655 fixes will be much appreciated. 10656 - I2C_RESET: Eliminate up_i2creset(). It should not be a global 10657 function; Now it is an I2C interface method. 10658 - PCA555: Add logic to make the PCA555 driver thread safe. 10659 - syslog: If syslog timestamping is enabled, don't try to get the time 10660 if the timer hardware has not yet been initialized. 10661 - AT24xx driver: Correct missing address calculation logic. From Frank 10662 Benkert. 10663 10664 * Networking: 10665 10666 - Networking drivers that support CONFIG_NET_NOINTS: Fix a race 10667 condition that can cause the TX poll timer to stop running. From 10668 Manuel Stuhn. 10669 - Timer Poll: Fix some logic when there are multiple network 10670 interfaces. In this case, TCP timeout events can really only being 10671 processed when the poll from the correct device is received. 10672 10673 * Atmel SAMV7 Drivers: 10674 10675 - SAMV7 USB HS device: The USB driver has had some issue that would 10676 occasionally cause loss of packets. Back last December, a fix was 10677 put in for this but the fix apparently worsens the problem; now 10678 causing hangs. The basic problem is that the number of busy banks 10679 (NBUSYBKS) status is not real time but is delayed. This was fixed; 10680 now when the DMA completes and NBUSYBKS > 0, the NBUSYBK is 10681 interrupt is enabled and the operations are deferred until NBUSYBKS 10682 is truly zero. 10683 10684 * Tools: 10685 10686 - tools/testbuild.sh: .config files were not being updated because 10687 (a) kconfig-conf was being called in the wrong directory and (b) 10688 apps/Kconfig had not yet been created. Now uses 'make 10689 olddefconfig'. 10690 10691 * Applications: apps/system: 10692 10693 - apps/system/i2c: The I2C tool now obeys it OS interfacing: it now 10694 uses an I2C character driver to access the I2C bus. 10695 - apps/system/cdcacm, usbmsc, and composite: Use new boardctl() 10696 instead of calling directly in the OS when possible. 10697 10698 * Applications: apps/netutils: 10699 10700 - apps/netutils/dhcpd: DHCPD no longer calls directly into the OS but 10701 uses the new network IOCTL commands to modify the ARP table. 10702 10703 * Applications: apps/modbus: 10704 10705 - apps/modbus/nuttx/portserial.c: Was not returning an error on 10706 failure to open the device driver. From Olololshka kokoko. 10707 10708 * Applications: apps/examples: 10709 10710 - apps/examples/usbserial, composite, usbterm: Use new boardctl() 10711 instead of calling directly in the OS when possible. There are 10712 still a few bad OS calls for USB device interfaces that do not yet 10713 have boardctl() commands. 10714 10715 * Applications: apps/platform: 10716 10717 - Moved C++ initialization logic out of the RTOS and into the 10718 application space, specifically to apps/platform/board, where it 10719 belongs. 10720 10721NuttX-7.16 Release Notes 10722------------------------ 10723 10724The 116th release of NuttX, Version 7.16, was made on June 1, 2016, 10725and is available for download from the Bitbucket.org website. Note 10726that release consists of two tarballs: nuttx-7.16.tar.gz and 10727apps-7.16.tar.gz. These are available from: 10728 10729 https://bitbucket.org/nuttx/nuttx/downloads 10730 https://bitbucket.org/nuttx/apps/downloads 10731 10732Both may be needed (see the top-level nuttx/README.txt file for build 10733information). 10734 10735Additional new features and extended functionality: 10736 10737 * Core OS: 10738 10739 - Power Management: Add activity domain to all PM interfaces and 10740 driver callbacks. If CONFIG_PM_NDOMAINS == 1, then the legacy 10741 behavior is preserved. If CONFIG_PM_NDOMAINS > 1, then multiple 10742 PM domains are supported. This will allow separate control for 10743 certain power management groups. For example, a network can be 10744 shut down without affect an ongoing UI (and vice versa). 10745 - board_app_initialize(): board_app_initialize() now accepts an 10746 argument that may be used to support initialization in different 10747 configurations. 10748 10749 * File System and Block and MTD Drivers: 10750 10751 - N25Qxxx: Add MTD support for Micron N25Qxxx family of QSPI flash. 10752 From Dave (ziggurat29). 10753 - SST26F: Add an MTD driver for SST26F spi/qspi flash devices (SPI 10754 mode only). From Sebastien Lorquet. 10755 - File Descriptor Detach: Add logic to detach a file structure from a 10756 file descriptor. This is for use only within the OS. It permits an 10757 open file or driver to be used across multiple threads. 10758 10759 * Networking and Network Drivers: 10760 10761 - listen()/accept(): Separate out psock_listen() and psock_accepti() 10762 for internal, thread independent OS usage (i.e., without a socket 10763 descriptor). 10764 - VNC Server: Add support for a VNC server. This logic is code 10765 complete and functional, but not well tested. 10766 10767 * Graphics and Graphic Drivers: 10768 10769 - Framebuffer driver: Add a display number to each interface in order 10770 to support multiple display devices. 10771 - VNC Server: Add support for a VNC server. This logic is code 10772 complete and functional, but not well tested. 10773 - LCD Backpack: Add support for PCF8574 LCD Backpack driver. This 10774 driver supports an interface board that is based on the PCF8574 I/O 10775 expander and supports the HD44780-based (or compatible) LCD modules. 10776 There are a myriad of different vendors of such, but they are 10777 principally the same, save wiring and minor features like jumpers 10778 for I2C addresses. This driver supports known and unknown variants. 10779 From Dave (ziggurat29). 10780 10781 * Common Device Drivers: 10782 10783 - RTC: Simplify the RTC interface. The old interface was way too 10784 complex and was not fully implemented anywhere. 10785 - BH1750FVI: Add a character driver for Rohm Ambient Light Sensor 10786 BH1750FVI. From Alan Carvalho de Assis. 10787 - CAN: Improve CAN error reporting. From Frank Benkert. 10788 - aes.h: Modifications to the crypto API needed for LPC43xx. From 10789 Alexander Vasiljev. 10790 - ADC: Interface no longer uses global adc_receive() call. Added a 10791 new bind() method to the ADC interface. Now the ADC upper half 10792 driver will register its receipt-of-data callback. This change 10793 allows the ADC lower half driver to be used with a differ ADC upper 10794 half. 10795 10796 * Simulation Platform: 10797 10798 - Linux Host Networking: Enhance networking support for the 10799 simulation under Linux. Includes updated support for Linux TUN/TAP, 10800 and the addition of support for Linux bridge devices. From Steve. 10801 10802 * ARMv7-A, ARMv7-R, and ARMv7-M: 10803 10804 - ARMv7-M: Convert more assembly language files for use with the IAR 10805 toolchain. From Kha Vo. 10806 - ARMv7-A: Complete re-design of SMP-related logic to initialize each 10807 CPUn, n > 0, when CONFIG_SMP=y. 10808 10809 * Atmel SAMV7: 10810 10811 - Add a JTAG config and ERASE config to Kconfig to set the 10812 CCFG_SYSIO SYSIO Pins. From David Sidrane. 10813 - System Reset: Add the up_systemreset interface to the samv7 arch. The 10814 approach is slightly different in that: 1) It enables ARCH_HAVE_RESET 10815 and allows the user to set if, and for how long, to drive External 10816 nRST signal. It also does not contain a default board_reset, as that 10817 really should be done in the config's src if CONFIG_BOARDCTL_RESET 10818 is defined. From David Sidrane. 10819 10820 * Atmel SAMV7 Boards: 10821 10822 - SAMV71-XULT: Add configuration(s) that were be used to verify VNC 10823 graphics output as well as mouse and keyboard input. 10824 10825 * NXP Freescale i.MX6 Boards: 10826 10827 - Sabre-6Quad: The basic i.MX6 port is complete. This is a minimal 10828 port at present and probably still has some as-of-yet-undiscovered 10829 issues. 10830 - Sabre-6Quad: Basic SMP NSH configuration is now working. But this 10831 is probably only because the SMP test case does not stress the 10832 logic. There are know outstanding SMP issues as noted in the 10833 Sabre-6Quad README.txt file. 10834 10835 * NXP Freescale LPC43xx: 10836 10837 - LPC4337jet100: Add definitions for the LPC4337jet100 chip. From 10838 Alexander Vasiljev. 10839 10840 * NXP Freescale LPC43xx Drivers: 10841 10842 - AES: Add AES support. From Alexander Vasiljev. 10843 10844 * STMicro STM32: 10845 10846 - STM32 L4: Add configuration options to allow SRAM2 to be used for 10847 heap, or not at all, and to zero-initialize it on OS start, or not 10848 at all. From Dave dev@ziggurat29.com. 10849 - STM32 L4: Add support for HSE and MSI clocks, and auto trim of MSI 10850 to LSE (needed for USB). From Dave (ziggurat29) 10851 - STM32 L4: Add support for unique id function to arch; modified board 10852 to support unique id boardctl. From Dave (ziggurat29) 10853 10854 * STMicro STM32 Drivers: 10855 10856 - STM32 F4 RTC: Add a custom RTC driver with support for alarms. From 10857 Neil Hancock. 10858 - STM32 L4 QSPI: Add a QSPI driver with DMA support and (optional 10859 memory mapped mode support. From Dave ziggurat29). 10860 - STM32, STM32 L4, and STM32 F7 Serial: Add support for compliant 10861 SD-style breaks. From David Sidrane. 10862 - STM32 L4 CAN: Add CAN support for STM32L4. From Sebastien Lorquet. 10863 - STM32 1-Wire: Add support for a custom 1-wire driver. The serial 10864 driver already supports a 1-wire interface, but this driver uses the 10865 same serial logic to implement a lower half driver much like the 10866 I2C lower half driver. From Aleksandr Vyhovanec. 10867 - STM32 L4 SPI: Add support for SPI 4 and 5 on stm32f411 chips. From 10868 Konstantin Berezenko. 10869 - STM32 ADC: Allow omitting use of channels in a lower part of PWM. 10870 From Pierre-noel Bouteville. 10871 - STM32 L4 I2C: Get I2C working for STM32L4. From Dave (ziggurat29). 10872 10873 * STMicro STM32 Boards: 10874 10875 - STM3220G-EVAL: Add support for both the IAR and uVision GCC IDEs. 10876 From Kha Vo. 10877 - STM32F429I Discovery: Add support for the uVision GCC IDE. From 10878 Kha Vo. 10879 - STM32F4 Discovery: Integrate BH1750FVI driver in the STM32F4 Discovery 10880 board. From Alan Carvalho de Assis. 10881 - STM32L476VG Discovery: Add support for QSPI based N25Qxxx flash. 10882 From Dave (ziggurat29) 10883 - STM32L476VG Discovery: Add board ioctls for allowing user application 10884 to cause QSPI memory mapped mode to be engaged and disengaged. Also 10885 partitioned QSPI flash for file system and other (eventually xip). 10886 From Dave (ziggurat29) 10887 - Nucleo-144: Basic port for the Nucleo-144 board with the STM32F746ZG 10888 MCU. From Kconstantin Berezenko. 10889 - STM32F103 Minimum: Add support for this minimual STM32F103CBT6 "blue" 10890 board. From Alan Carvalho de Assis. 10891 - STM32F411E Discovery: Add basic configuration for stm32f411e-disco 10892 board with STM32F411VE chip. From Konstantin Berezenko. 10893 10894 * Build/Configuration System: 10895 10896 - Moved NuttX repository to https://bitbucket.org/nuttx/nuttx. 10897 Eliminated use of sub-modules. 10898 - Add support for the IAR toolchain for the limited case of the ARMv7-M 10899 architecture and the STM32 chip. From Aleksandr Vyhovanec. 10900 - make export: Pass top-level make to the script to allow -j greater 10901 than 1. From David Sidrane. 10902 - fs/Kconfig: Allow CONFIG_FS_WRITABLE to be manually selectable. This 10903 is needed when there are no writable file systems, but write support 10904 is still needed in BCH or FTL. 10905 - arch/*/Makefile: Add definitions that can be overrided to use GCC 10906 instead of LD in the final link. From Paul Alexander Patience . 10907 10908 * Applications: apps/netutils: 10909 10910 - apps/netutils/esp8266: ESP8266 driver application. From Pierre-noel 10911 Bouteville. 10912 10913 * Applications: apps/examples: 10914 10915 - apps/examples/alarm: Add a simple test of the ALARM iotcl calls of 10916 the RTC driver. 10917 - apps/examples/nximage: Add a configuration option to select 10918 greyscale. 10919 10920 * Platforms: apps/platform: 10921 10922 - apps/platform/nucleo-144: Add platform files for NUCLEO-144 10923 (NUCLEO-F746ZG). From Mark Olsson. 10924 - apps/examples/media: You can now override the default device driver 10925 path by providing an alternal path on the command line. From 10926 S�bastien Lorquet. 10927 10928Works-In-Progress: 10929 10930 * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were 10931 introduced in NuttX-7.15. Work has continued on this effort on 10932 forks from the main repositories, albeit with many interruptions. 10933 The completion of this wireless feature will postponed until at 10934 least NuttX-7.17. 10935 10936 * i.MX6 SMP. Partially functional, but there is more that still 10937 needs to be done. 10938 10939Bugfixes. Only the most critical bugfixes are listed here (see the 10940ChangeLog for the complete list of bugfixes and for additional, more 10941detailed bugfix information): 10942 10943 * Core OS: 10944 10945 - Various places: Search for places where a stray semicolon following 10946 an if condition cause the if body to be executed unconditionally. 10947 Fixes in all SAM DMA logic, unionfs, OS signalling logic, and others. 10948 - enter/leave_critical_section() may attempt to access task lists 10949 before they have been initialized in the SMP configuration. 10950 10951 * File System/Block Drivers: 10952 10953 - SMART MTD: Return code of smart_scan not checked, can cause success 10954 result in failure case, leading to 'dev' pointer being invalid. From 10955 Dave (ziggurat29) 10956 - mount: Fix a backward debug assertion. Noted by David Sidrane. 10957 10958 * Common Drivers: 10959 10960 - NRF24L01: Fix backward calculation of relative frequency. Noted by 10961 Henry Zhang. 10962 - PCA9555 I/O expander: Fix an error in the PCA9555 driver: Under 10963 certain error conditions, interrupts were not being re-enabled. 10964 Sebastien Lorquet. 10965 - ADS1255: Must not do SPI access from interrupt handler. Use the 10966 worker thread instead. Must also lock the SPI bus before using it. 10967 - Several SPI-based drivers modified. All drivers that use SPI must 10968 call SPI_LOCK and SPI_UNLOCK. This is not optional. 10969 - MS583730: Fix a bug in crc computation for ms583730. Implement 10970 POSIX read. 10971 10972 * Atmel SAMV7: 10973 10974 - Fix typo in MATRIX register definitions. From Stefan Kolb. 10975 - SAMV7 Tickless Mode: This is a fix to a problem in the handling of 10976 the oneshot timer. Due to a wrong assumption concerning the behavior 10977 directly after the start of the timer/counter the function 10978 sam_oneshot_cancel(�) calculates the wrong remaining time. The code 10979 assumes that the counter register is zero directly after the start 10980 of the timer, but this is not true. To start the time/counter a 10981 software trigger is invoked, this trigger starts the timer/count and 10982 sets the counter register to zero, but the reset of the counter 10983 register is not performed instantly. According to the datasheet: 10984 "The counter can be reset by a trigger. In this case, the counter 10985 value passes to zero on the next valid edge of the selected clock." 10986 Thus the counter is set to zero between 0 and USEC_PER_TICK 10987 microseconds after the clock was started. 10988 In my fix I use the freerun count value to determine if at least one 10989 tick passed since the start of the timer and thus if the value of 10990 the oneshot counter is correct. I also tried to use the function 10991 up_timer_gettime(�) to achieve this but, at least if compiled with 10992 no optimization the problem vanishes without using the value of the 10993 function, the function call takes too long. 10994 Another problem treated in the fix is that if the oneshot timer/counter 10995 is canceled, we only know the remaining time with a precision of 10996 USEC_PER_TICK microseconds. This means the calculated remaining time 10997 is between 0 and USEC_PER_TICK microseconds too long. To fix this I 10998 subtract one tick if the calculated remaining time is greater than 10999 one tick and otherwise set the remaining time to zero. By doing so 11000 the measured times are much more precise as without it. From Stefan 11001 Kolb. 11002 11003 * Atmel SAMA5: 11004 11005 - SAMA5: Stefan Kolb's change to the SAMV7 Oneshot Timer should also 11006 be applied to the SAMA5 oneshot time since the drivers are identical. 11007 11008 * Atmel SAM3/4: 11009 11010 - SAM3/4: Stefan Kolb's change to the SAMV7 Oneshot Timer should also 11011 be applied to the SAM3/4 oneshot time since the drivers are identical. 11012 11013 * Atmel SAMV7 Drivers: 11014 11015 - SAMV7 TWIHS (as well as SAM3/4 and SAMA5: Ensure that the TWIHS 11016 (i2c) hw get's its clock set when the sequence of 11017 sam_i2cbus_initialize(), sam_i2cbus_uninitialize(), then 11018 sam_i2cbus_initialize() or twi_reset() is called. I found this a 11019 while back in the stm32 family, so there may be more arch-es with 11020 this sort of bug. I suppose any driver that has the notion of "do 11021 not set the freq if it is already set" could be suspect. From David 11022 Sidrane. 11023 - USBHS Device: Remove disabling of whole USB on suspend of USBHS. 11024 This fix removes the disabling of the whole USB peripheral on 11025 suspend interrupt. Its enough to freeze the clock instead. When 11026 disabling the whole peripheral, the next wakeup-interrupt comes up 11027 with an disabled clocking. The unfreeze clock has no effect, because 11028 the master clock is disabled. This makes all registers, including 11029 the IDR unwriteable and the IRQ falls in an endless loop blocking 11030 the whole system. Furthermore the disabling of the peripheral clock 11031 prevents hotplugging or reconnecting the USB. From Frank Benkert. 11032 - MCAN: Fix missing unlock of device in MCAN mcan_txempty(). From 11033 Frank Benkert. 11034 11035 * STMicro STM32: 11036 11037 - STM32 L4 Clocking: Problem with resetting backup domain clears 11038 clocking options set up before in *rcc.c use INITS flag to avoid 11039 magic reg value to detect power up reset state of RTC correct a 11040 problem clearing interrupt flags (they weren't) which prevented an 11041 alarm from ever being used more than once per reset cycle. From 11042 Dave (ziggurat29) 11043 11044 * STMicro STM32 Drivers: 11045 11046 - STM32L4 SPI: That STM32Lr SPI driver is quite different. They now 11047 handle frames of arbitrary size between 4 and 16 bits. It was broken 11048 before a new bit has to be set (RX fifo threshold) to handle <= 8-bit 11049 transactions. If not set, the default is 16-bit packed >=8-bit 11050 frames and the RXNE bit is never set (it is set when 16-bits are 11051 received). weird things as always. This also add 8-bit access 11052 routines to the data register, because a 16-bit access to the data 11053 register when the frame size is below 9 bits is interpreted as a 11054 packed dual frame exchange. Sebastien Lorquet. 11055 - STM32: Correct some bad commits that broke the LTDC display example. 11056 From Marco Krahl. 11057 - STM32 F4 RTC: Fix logic in F4 RTCC driver that prevent ALARM 11058 interrupt. From Neil Hancock. 11059 - STM32 F1 ADC: Fix STM32 ValueLine ADC IRQ number selection. From 11060 David Sidrane. 11061 11062 * STMicro STM32 Boards: 11063 11064 - STM32F429I Discovery: Correct some bad commits that broke the LTDC 11065 display example. From Marco Krahl. 11066 11067 * TI Tiva: 11068 11069 - GPIO Interrupts: Fix a bug of GPIO falling-edge interrupt for tiva. 11070 From Young. 11071 11072 * C Library: 11073 11074 - math: Add a NAN test on 'x' in asin function of lib_asin.c. Suggested 11075 by Pierre-noel Bouteville. 11076 11077 * Build/Configuration System: 11078 11079 - Several Makefiles: Add .PHONY definitions to prevent 'clean up to date' 11080 message weirdness when 'make clean' is done with no .config or 11081 Make.defs file. 11082 11083NuttX-7.17 Release Notes 11084------------------------ 11085 11086The 117th release of NuttX, Version 7.17, was made on July 25, 2016, 11087and is available for download from the Bitbucket.org website. Note 11088that release consists of two tarballs: nuttx-7.17.tar.gz and 11089apps-7.17.tar.gz. These are available from: 11090 11091 https://bitbucket.org/nuttx/nuttx/downloads 11092 https://bitbucket.org/nuttx/apps/downloads 11093 11094Both may be needed (see the top-level nuttx/README.txt file for build 11095information). 11096 11097Additional new features and extended functionality: 11098 11099 * File System and Block and MTD Drivers: 11100 11101 - drivers/mtd: Add a driver of IS25xP SPI flash devices. Based on 11102 sst25xx driver. From Marten Svanfeldt. 11103 11104 * Networking and Network Drivers: 11105 11106 - Break out internal interface psock_ioctl(). 11107 11108 * Common Device Drivers: 11109 11110 - PTYs: Added support for pseduo-terminals: Device drivers that can be 11111 used for communications between tasks (usually with re-directed I/O). 11112 Based on existing pipe logic. 11113 - Button upper half driver: Added support for poll(). 11114 - CAN: Add support for poll. From Paul Alexander Patience. 11115 - GPIO: Add support for a simple GPIO driver. It supports only pre- 11116 configured input, output, and interrupting pins with basic input and 11117 output operations. Interrupt events can lead to notification via a 11118 signal. 11119 - I/O Expander: Shadow-Mode: The output- and configuration registers of 11120 the IO-Expander are held in the microcontrollers memory and only 11121 written to the IO-Expander. This reduces bus traffic and is more 11122 error-proof than the normal read-modify-write operation. Retry Mode: 11123 If enabled and an error occurs while writing to the IO-Expander the 11124 current transmission is automatically repeated once. From Michael 11125 Spahlinger. 11126 - Pipes/FIFOs: Add support to allocating different sizes for pipe and 11127 fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo() 11128 and pipe(), but allow control of the size of the underlying, in-memory 11129 circular buffer. Move pipe() and mkpipe() to the C library, they are 11130 no longer core OS interfaces. Capability currenty used only by PTY 11131 logic to support, configurable, smaller buffers for PTYs. 11132 11133 * SYSLOG/Debug Output: 11134 11135 - SYSLOG: Consolidated all SYSLOG logic in drivers/syslog. Added an 11136 abstraction layer that supports: (1) redirection of SYSLOG outpout. 11137 This is usually so that you can boot with one SYSLOG output but 11138 transition to another SYSLOG output when the OS has initialialized, 11139 (2) adds common serialization of interrupt output as a configuration 11140 option. Without this configuration setting, interrupt level output 11141 will be asynchronous. And (3) vsyslog is now a system call and is 11142 usable with other-than-FLAT builds. 11143 - SYSLOG: syslog() will now automatically redirect output to 11144 lowsyslog() if called from an interrupt handler. 11145 - Extended SYSLOG logic so that we can send SYSLOG output to a file. 11146 - SYSLOG character device channel will now expand LF to CR-LF. 11147 Controllable with a configuration option. 11148 - Add a SYSLOG character device that can be used to re-direct output 11149 to the SYSLOG channel (Not be be confused the SYSLGO output to a 11150 character device). 11151 - Debug features are now enabled separately from debug output. 11152 (1) CONFIG_DEBUG is gone. It is replaced with CONFIG_DEBUG_FEATURES. 11153 (2) The macros dbg() and vdbg() have renamed as _err() and _info(), 11154 respectively. This also applies to all of the variants as well, 11155 XXdbg() and XXvdbg(). (3) Add a new debug level, _warn() (and 11156 all variants XXwarn(), XXvwarn(), etc.). (4) Debug assertions can 11157 now be enabled separately from debug output. (5) You can now enable 11158 subsystem/device driver debug output at different output levels. For 11159 example, CONFIG_DEBUG_FS no longer enables file system debug output 11160 It enables general file system debug logic and enables selection of 11161 CONFIG_DEBUG_FS_ERROR, CONFIG_DEBUG_FS_WARN, and CONFIG_DEBUG_FS_INFO. 11162 - Since the SYSLOG layer now automatically handles low-level vs. 11163 high-level output, the low-level (ll) variants of the debug macros 11164 were eliminated. 11165 - Reviewed all uses of *err(). These macro family should indicate 11166 only error conditions. Convert *err() to either *info() or add 11167 ERROR:, depending on if an error is reported. 11168 - _alert(): New debug macro: _alert(). This is high priority, 11169 unconditional output and is used to simplify and standardize crash 11170 error reporting. 11171 - Many CONFIG_DEBUG_* options did not have matching macros defined in 11172 include/debug.h. Rather, there were various definitions scattered 11173 throughout the sourse tree. These were collected together and 11174 centralized with single macro definitions in include/debug.h 11175 11176 * Simulation Platform: 11177 11178 - Added the simulated QSPI (N25Q) flash to the simulation and extened 11179 flash simulation capabilities to run with MTD drivers based on config 11180 options (currently m25p, sst26 and w25). From Ken Pettit. 11181 11182 * Atmel SAMV7 Drivers: 11183 11184 - SPI: SPI-Freq. 40MHz; VARSELECT; hw-features This change adds the 11185 following improvements: 11186 11187 o Increase the allowed SPI-Frequency from 20 to 40 MHz. 11188 o Correct and rename the "VARSELECT" option This option was 11189 included in the code as "CONFIG_SPI_VARSELECT" but nowhere 11190 defined in a Kconfig file. The change renames it to 11191 "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation 11192 according the datasheet of Atmel. In short, this option 11193 switches the processor from "fixed peripheral selection" 11194 (single device) to "variable peripheral selection" (multiple 11195 devices on the bus). 11196 o Add a new Function to the interface to control the timing and 11197 delays of the chip according the ChipSelect lines. This function 11198 can control the delay between the assertion of the ChipSelect and 11199 the first bit, between the last bit and the de-assertion of the 11200 ChipSelect and between two ChipSelects. This is needed to tune 11201 the transfer according the specification of the connected devices. 11202 o Add three "hw-features" for the SAMV7, which controls the behavior 11203 of the ChipSelect: 11204 - force CS inactive after transfer: this forces a (short) de- 11205 assertion of the CS after a transfer, even if more data is 11206 available in time 11207 - force CS active after transfer: this forces the CS to stay 11208 active after a transfer, even if the chip runs out of data. 11209 Btw.: this is a prerequisit to make the LASTXFER bit working 11210 at all. 11211 - escape LASTXFER: this suppresses the LASTXFER bit at the end 11212 of the next transfer. The "escape"-Flag is reset automatically. 11213 11214 From Frank Benkert 11215 - TWISHS: Driver improvements from Michael Spahlinger. 11216 - GPIO-Driver fixed for Open-Drain Pins: 11217 11218 o sam_gpioread: Now the actual line level from the pin is read 11219 back. This is extremely important for Open-Drain Pins, which 11220 can be used bidirectionally 11221 o Re-Implemented twi_reset-function and enhanced it so it can be 11222 called from inside the driver (see next point) 11223 o Glitch-Filter: Added a configuration option to enable the twi- 11224 built-in glitch filter 11225 o Added a "Single Master Mode": In EMC Testing the TWI-Bus got 11226 stuck because the TWI-Master detected a Multi-Master access (but 11227 there is no second master). With the option "Single Master" we 11228 detect these events and automatically trigger a twi_reset. We 11229 also do an automatic recovery if a slave got stuck (SDA stays 11230 low). 11231 11232 With the above changes I�C-Bus reliability in harsh environments (eg. 11233 EMC) is greatly improved. The small change in the GPIO-Driver was 11234 necessary because otherwise you cannot read back the correct line 11235 status of Open-Drain Outputs and this is needed by the twi_reset 11236 function. From Michael Spahlinger 11237 11238 * NXP Freescale LPC43xx Drivers: 11239 11240 - EMC: Extend LPC43xx EMC code to support SDRAM on a dynamic memory 11241 interface. From Vytautas Lukenskas. 11242 11243 * NXP Freescale Kinetis: 11244 11245 - Kinetis K64: Add basic support for the K64 family. I leveraged the 11246 changes from https://github.com/jmacintyre/nuttx-k64f and merged 11247 into the existing kinetis code with a lot of changes and additions 11248 (like pin multiplexing definitions). 11249 11250 * NXP Freescale Kinetis Drivers: 11251 11252 - Add a KinetisUSB device controller driver. Derived from the pic32mx 11253 usb driver, which uses the same usb controller. From kfazz. 11254 - Kinetis pwm support, based on the KL pwm driver. From kfazz. 11255 - Kinetis Ethernet: Add support for the KSZ8081 PHY. 11256 - Kinetis Ethernet: Modified Ethernet driver to try all PHY addresses 11257 and then only fail if the driver cannot find a usable PHY address. 11258 This means that you no longer have to specific the PHY address in 11259 advance. 11260 - Kinetis Ethernet: Add support for CONFIG_NET_NOINTS. The driver no 11261 longer runs the networking at interrupt level but can defer interrupt 11262 work to the high-priority work queue. 11263 11264 * NXP Freescale Kinetis Boards: 11265 11266 - Teensy-3.x: Add USB support and a usbnsh configuration. 11267 From kfazz (2016-06). 11268 - Freedom-K64F: Add support for the NXP Freedom-K64F board at 120MHz. 11269 This is primarily the work of Jordan Macintyre. I leveraged this 11270 code from https://github.com/jmacintyre/nuttx-k64f which was, itself, 11271 a leverage from the old K60 TWR configuration. This includes 11272 significant corrections (LEDs, buttons, README, etc) and extensions 11273 and updates to match more recent BSPs. 11274 - Freedom-K64F: Added a configuration that supports networking. 11275 11276 * STMicro STM32: 11277 11278 - STM32 F1-4: Added support for the STM32F105R. From Konstantin 11279 Berezenko. 11280 - STM32 F4: Added support for the STM32FF76xxx and STM32FF7xx 11281 families. From David Sidrane. 11282 - STM32 F1-4: Add support for Tickless mode (two timer 11283 implementation). From Max Neklyudov. 11284 - STM32 L4: Add support for tickless OS, and incidentally timers, 11285 PWM, oneshot, free-running.... From ziggurat29. 11286 11287 * STMicro STM32 Drivers: 11288 11289 - STM32 F1-4: Add the up_getc() function to STM32 in order to support 11290 the minnsh configuration. From Alan Carvalho de Assis. 11291 - STM32 F7: Add SPI driver. From David Sidrane. 11292 - STM32 F7: Add SPI, I2C, and ADC drivers. From Lok Tep. 11293 - STM32 L4: Add ioctls to set/get CAN bit timing in stm32l4. Add 11294 ioctl hooks to allow future management of can id filters. From 11295 Sebastien Lorquet. 11296 - STM32 L4: Add some CAN mode IOCTL calls. These will be useful for 11297 device autotest when the application boots. They are redundant 11298 with the CONFIG_CAN_LOOPBACK option, which can now just be 11299 interpreted as a default setting. From Sebastien Lorquet. 11300 - STM32 F1-4: Port STM32L4 CAN IOCTLs to STM32. From Sebastien Lorquet. 11301 - STM32 L4: Implementation of loopback IOCTLs. From Sebastien 11302 Lorquet. 11303 - STM32 F7: Added SDMMC1 support for stm32F7 74-75. From Lok Tep. 11304 - STM32 F7: Add USB support. From Lok Tep. 11305 - STM32 F7: Added PWR, RTC, and BBSRAM support for stm32f7. From David 11306 Sidrane. 11307 - STM32 F7: Added STMF7xxx RTC. From David Sidrane. 11308 - STM32 F7: Added STM32F7 DBGMCU. From David Sidrane. 11309 - STM32 L4: Port support for both RX FIFOs from STM32 CAN. From Paul 11310 Alexander Patience. 11311 11312 * STMicro STM32 Boards: 11313 11314 - Added a minnsh configuration for the STM32F103-Minimum board. From 11315 Alan Carvalho de Assis . 11316 - Added support for the Nucleo-F767ZI board. From David Sidrane. 11317 - Nucleo-144/Nucleo-F767ZI: Add test for STM32 F7 SPI. From David 11318 Sidrane. 11319 - Nucleo-144: Added SDMMC support to Nucleo-144. From David Sidrane. 11320 - Olimex STM32-E4077: Add support for Olimex STM32 E407 board. From 11321 Mateusz Szafoni. 11322 - Nucleo-144: Added USB OTG device to Nucleo-144. From David Sidrane. 11323 - Nucleo-144: Added bbsram test to Nucleo-144. From David Sidrane. 11324 - STM32F4 Disovery: Add CAN support for STM32F4 Discovery. From 11325 Matthias Renner. 11326 - STM32F4 Disovery: added a canard configuration files. From 11327 Matthias Renner. 11328 - STM32F4 Discovery: Add FPU support for ostest for the STM32F4 11329 Disovery platform. From David Alessio. 11330 - STM32L476 Discovery: Update stm32l476 disco to include init code for 11331 smartfs and nxffs for cases where those fs are included in build. 11332 From ziggurat29. 11333 11334 * C Library/Header Files: 11335 11336 - include/assert.h: Check if NDEBUG is defined. From Paul Alexander 11337 Patience. 11338 - assert.h: Define static assert for C++ usage. From Paul Alexander 11339 Patience. 11340 - Add crc64 support. From Paul Alexander Patience. 11341 - hex2bin: Move the portable library portion of apps/system/hex2bin 11342 the C library with the OS internals. It is used in certain internal 11343 boot-loader builds. 11344 - Add raise(). 11345 - libm: This change should significantly improve the performance of 11346 single precision floating point math library functions. The vast 11347 majority of changes have to do with preventing the compiler from 11348 needlessly promoting floats to doubles, performing the calculation 11349 with doubles, only to demote the result to float. These changes only 11350 affect the math lib functions that return float. From David Alessio. 11351 - printf(): If there are no streams, let printf() fall back to use 11352 syslog() for output. 11353 - Move pipe() and mkpipe() to nuttx/libc, they are no 11354 longer core OS interfaces. Capability currenty used only by PTY logi 11355 to support, configurable, smaller buffers for PTYs. 11356 - Move driver-related files from include/nuttx to include/nuttx/drivers. 11357 Move driver related prototypes out of include/nuttx/fs/fs.h and into 11358 new include/drivers/drivers.h. 11359 - include /nuttx/lib: Move library-related files from include/nuttx to 11360 include/nuttx/lib. 11361 11362 * Build/Configuration System: 11363 11364 - Custom Board Configuration: Add logic to support custom board 11365 directories that include a Kconfig file. During the context phase 11366 of the build, any Kconfig file in the custom board directory is 11367 copied into configs/dummy, replacing the existing Kconfig file with 11368 the target Kconfig file. 11369 - Remove the includes/apps link to apps/include. It is no longer 11370 used. From Sebastien Lorquet. 11371 11372 * Tools: 11373 11374 - tools/tesbuild.sh will now build NxWM configurations. 11375 11376 * Appplication Build/Configuration System: 11377 11378 - Change to the way that apps/ Kconfig files are generated in 11379 order to better support reuse of the apps/ directory in NuttX 11380 products. Changes include: Make the full tree use wildcards 11381 make.defs, Add empty preconfig rules to 'leaf' makefiles, Use 11382 directory.mk for recursive dir makefiles, Individual app kconfig 11383 fixes, Recursive Kconfig autogeneration, Add kconfig files for 11384 pcode and tiff, and fix a gitignore rule, From S�bastien Lorquet. 11385 - apps/include directory structure reorganized. There are no longer 11386 any header files in the apps/include/. directory. Rather, sub- 11387 directories were added to match the partitioning of apps/ sub- 11388 directories and the header files were moved into the appropriate 11389 sub-directory. This change is intended to help with some changes 11390 being considered by S�bastien Lorquet. 11391 - Call all includes from <apps/bla/bla.h> to "bla/bla.h". From Sebastien 11392 Lorquet. 11393 - Add apps/include to include path in top-level Make.defs file. 11394 11395 * Applications: apps/nshlib: 11396 11397 - Make NSH net-initialization be a configuration option. From Marten 11398 Svanfeld. 11399 - Add NTP client initialization in NSH network startup logic. From 11400 David S. Alessio . 11401 - 'ps' command now prints out the stack usage if stack coloration is 11402 enabled. From Frank Benkert. 11403 - Allow stack usage to be disabled on constrained systems. From David 11404 Sidrane. 11405 11406 * Applications: apps/netutils: 11407 11408 - NTP Client: Add retries. From David S. Alessio. 11409 - NTP Client: The NTP client will now optionally use pool.ntp.org as 11410 the NTP server; and reset the retry count upon success -- more robust. 11411 From David Alessio. 11412 - ESP8266: Add logic to set the BAUD rate. From Pierre-noel Bouteville. 11413 - ESP8266: In Kconfig, select ARCH_HAVE_NET when NETUTILS_ESP8266 is 11414 selected. This allows, among other things, support for network debug 11415 output. From Pierre-noel Bouteville. 11416 11417 * Applications: apps/fsutils: 11418 11419 - flash_eraseall: IOCTL wrapper for MDCIO_BULKERASE command. Was in 11420 nuttx/drivers/mtd. Moved to apps/fsutils because the call directly into 11421 the OS was incorrect. 11422 11423 * Applications: apps/canutils: 11424 11425 - canlib: Basic CAN utility library. From Sebastien Lorquet. 11426 11427 * Platforms: apps/system: 11428 11429 - flash_eraseall: Now uses the IOCTL wrapper at apps/fsutils/flash_eraseall. 11430 11431 * Platforms: apps/platform: 11432 11433 - Add platform files for Olimex STM32 E407. From Mateusz Szafoni. 11434 11435 * Applications: apps/examples: 11436 11437 - apps/examples/canard: Add canard example application. From 11438 Matthias Renner. 11439 - apps/examples/pty_test: PTY test program. From Alan Carvalho de 11440 Assis. 11441 11442Works-In-Progress: 11443 11444 * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were 11445 introduced in NuttX-7.15. Work has continued on this effort on 11446 forks from the main repositories, albeit with many interruptions. 11447 The completion of this wireless feature will postponed until at 11448 least NuttX-7.18. 11449 11450 * i.MX6 SMP. Partially functional, but there is more that still 11451 needs to be done. 11452 11453Bugfixes. Only the most critical bugfixes are listed here (see the 11454ChangeLog for the complete list of bugfixes and for additional, more 11455detailed bugfix information): 11456 11457 * Core OS: 11458 11459 - semaphores: Need to set errno to EINVAL on errors in sem_post() 11460 and sem_wait(). From Paul Alexander Patience. 11461 11462 * File System/Block Drivers/MTD Drivers: 11463 11464 - Several MTD FLASH drivers nullify the freed 'priv' structure and 11465 failed to return NULL as stated in the comments. Result, will 11466 operate on a NULL pointer later. Noted by David Sidrane. 11467 - VFS ioctl(). Per comments from David Sidrane, file_ioctl() should 11468 not return succeed if the ioctl method is not supported. It 11469 probably should return ENOTTY in that case. 11470 - SST26 Driver: Before accessing the sst26 flash, the "Global Unlock" 11471 command must me executed, which I do in the sst26 driver. BUT re- 11472 reading the datasheet, the WREN instruction is required to enable 11473 the execution of this command. This was not done. I have no idea how 11474 the driver currently works except by chance. The writes should never 11475 happen at all, the flash is half-enabled! From Sebastien Lorquet. 11476 - N25Qxx Driver: Alter the notion of 'blocksize' to be equivalent to 11477 'flash write page size' in order to align with assumptions in the 11478 smartfs driver (at least, maybe other things do as well). Correct a 11479 bug that was previously masked by having blocksize=eraseblocksize 11480 which would cause buffer overflows and delicious hardfaults. 11481 Trivial spelling changes in comments, etc. From ziggurat29. 11482 - SmartFS: Fix a 32-byte memory leak. From Ken Pettit. 11483 - SMART MTD layer: Fixes freesector logic error when sectorsPerBlk=256, 11484 adds DEBUGASSERT for invalid geometry and additional memory debug 11485 logic. Also fixes the dangling pointer on error bug. From Ken 11486 Pettit. 11487 11488 * Common Drivers: 11489 11490 - USB CDC/ACM Device Class: cdcacm_unbind leaks write request objects. 11491 This arises due to freeing the bulk IN endpoint before the loop 11492 that frees the requests via cdcasm_freereq. That function checks 11493 the parameters and skips the freeing if either is NULL. Freeing 11494 the bulk IN enpoint will cause the first param to be NULL, thereby 11495 bypassing the free operation. To fix, I moved the release of the 11496 bulk IN endpoint until after to loop (much as was the case for the 11497 OUT and read requests, which did not exhibit the problem). From 11498 ziggurat29. 11499 - Pipes and FIFOs: Add missing configuration for pipe ring buffer 11500 size. From Frank Benkert. 11501 - UART 16550: Handle when CONFIG_SERIAL_UART_ARCH_IOCTL is not 11502 enabled. From Heath Petersen. 11503 - Common Serial Upper Half: Fix a race condition noted by Stefan 11504 Kolb. Between the test if the TX buffer is full and entering a 11505 critical section, bytes may be removed from the TX buffer making 11506 the wait unnecessary. The unnecessary wait is an inefficiency, 11507 but not really a problem. But with USB CDC/ACM it can be a problem 11508 because the entire TX buffer may be emptied when we lose the race. 11509 If that happens that uart_putxmitchar() can hang waiting for data 11510 to be removed from an empty TX buffer. 11511 - USB MSC Device Class: Add locks when removing request from queue. 11512 From Wolfgang Reissnegger. 11513 - USB MSC Device Class: Fix reversed logic on waiting for SCSI thread 11514 start. The scsi thread was waiting for the wrong condition. 11515 However, this was masked by the fact that the code creating the 11516 scsi thread was also holding usbmsc_scsi_lock(priv) while 11517 initializing data, hence this lock synchronized the scsi thread 11518 start with init completion. From Wolfgang Reissnegger. 11519 11520 * Graphics and Graphic Drivers: 11521 11522 - Correct conditional compilation in ST7565 LCD driver. From Pierre- 11523 noel Bouteville 11524 11525 * Networking: 11526 11527 - In both IPv6 and IPv4 incoming logic: (1) Should check if the 11528 packet size is large enough before trying to access the packet 11529 length in the IP header. (2) In the comparison between the IP 11530 length and the full packet length, need to subtract the size of 11531 he link layer header before making the comparison or we will get 11532 false positives (i.e., the packet is really too small) 11533 - TCP Networking: While working with version 7.10 I discovered a 11534 problem in TCP stack that could be observed on high network load. 11535 Generally speaking, the problem is that RST flag is set in 11536 unnecessary case, in which between loss of some TCP packet and its 11537 proper retransmission, another packets had been successfully sent. 11538 The scenario is as follows: NuttX did not receive ACK for some sent 11539 packet, so it has been probably lost somewhere. But before its 11540 retransmission starts, NuttX is correctly issuing next TCP packets, 11541 with sequence numbers increasing properly. When the retransmission 11542 of previously lost packet finally succeeds, tcp_input receives the 11543 accumulated ACK value, which acknowledges also the packets sent in 11544 the meantime (i.e. between unsuccessful sending of lost packet and 11545 its proper retransmission). However, variable unackseq is still set 11546 to conn->isn + conn->sent, which is truth only if no further 11547 packets transmission occurred in the meantime. Because of incorrect 11548 (in such specific case) unackseq value, few lines further condition 11549 if (ackseq <= unackseq)is not met, and, as a result, we are going to 11550 reset label. From Jakub Lagwa. 11551 11552 * ARMv7-M: 11553 11554 - ARM stack check: Fix double fault on IDLE task with stack size = 0. 11555 From David Sidrane. 11556 11557 * Atmel SAMV7 Drivers: 11558 11559 - CAN: CAN Message Filtering fixed: (1) stdfilters didn't work because 11560 the filter was never enabled (wrong number of bits to shift), and 11561 (2) Filters were never used because the configuration register 11562 cannot be written without using the initialization mode. Both bugs 11563 are fixed by this change. Filtering has been tested with both 11564 standard and extended identifiers and is now working properly. From 11565 Michael Spahlinger. 11566 11567 * Atmel SAMA5: 11568 11569 11570 * Atmel SAM3/4 Drivers: 11571 11572 - Fix some errors in AFEC header file. From OrbitalFox. 11573 - DAC: DACC_WPMR_WPKEY_MASK -> DACC_WPMR_WPKEY. From Wolfgang 11574 Reissnegge. 11575 - Timer: Fix ops check in TCIOC_STOP. From Wolfgang Reissnegge. 11576 - I2C: Fix reversed logic in twi_startmessage(). From Wolfgang 11577 Reissnegger. 11578 - SAM3/4 UDP: Fix handling of endpoint RX FIFO banks. This fixes 11579 a race condition where the HW fills a FIFO bank while the SW is 11580 busy, resulting in out of sequence USB packets. 11581 11582 * Atmel SAMV7 Drivers: 11583 11584 - USBHS Device: This change solves a problem which causes data loss 11585 while sending data via USB. This problem is caused by an incorrect 11586 handling of the endpoint state in the USB driver sam_usbdevhs. This 11587 leads under some circumstances to situations in which an DMA 11588 transfer is setup while a previous DMA transfer is currently active. 11589 Amongst other things I introduced the new endpoint state 11590 USBHS_EPSTATE_SENDING_DMA for the fix. To reproduce the problem, I 11591 used a program which send as many data as possible via a CDC/ACM 11592 device and verified the received data on the PC. From Stefan Kolb. 11593 11594 * NXP Freescale Kinetis Drivers: 11595 11596 - Timers: Support up to 8 channels per timer. From kfazz. 11597 11598 * NXP Freescale Kinetis Boards: 11599 11600 - Teensy 3.x clock fixes: The High Gain bit in MCG_C1 was preventing 11601 teensy from booting except after a programming session. The second 11602 change doesn't appear to change any functionality, but complies with 11603 restrictions in the k20 family reference manual on FEI -> FBE clock 11604 transiions. From kfazz. 11605 11606 * NXP Freescale LPC17xx Drivers: 11607 11608 - LPC17 Ethernet: Needs to correctly ignore PHYID2 revision number 11609 when comparing PHY IDs. 11610 11611 * NXP Freescale LPC43xx Drivers: 11612 11613 - Fix errors in GPIO interrupt logic. From v01d (phreakuencies) 11614 - Ethernet: Correct auto-negotiation mode in the LPC43xx Ethernet. 11615 From Alexander Vasiljev 11616 - Writing zero to NVIC_IRQ_ENABLE has no effect. Disable interrupts 11617 with NVIC_IRQ_CLEAR. From Paul Alexander Patience. 11618 - SPIFI: If CONFIG_SPIFI_SECTOR512 undefined, lpc43_bwrite doesn't do 11619 actual write (probably copy/paste errors). Still not sure about 11620 current state of lpc43_spifi implementation, but for me NXFFS works 11621 with this change. From Vytautas Lukenskas. 11622 11623 * Qemu-i486: 11624 11625 - Fix qemu-i486/ostest/Make.defs test for M32. From Heath Petersen. 11626 11627 * SiLabs EFM32 Drivers: 11628 11629 - Fix EFM32 FLASH conditional compilation. From Pierre-noel 11630 Bouteville 11631 - Writing zero to NVIC_IRQ_ENABLE has no effect. Disable interrupts 11632 with NVIC_IRQ_CLEAR. From Paul Alexander Patience. 11633 11634 * STMicro STM32: 11635 11636 - STM32 F1-F4: In PWM driver, just update duty if frequency is not 11637 changed and PSM started. This removeis glitch or blinking when 11638 only duty is frequently changed. From Pierre-noel Bouteville. 11639 11640 * STMicro STM32 Drivers: 11641 11642 - STM32 F7: Fixed STM32F7 DMA stm32_dmacapable. DMA working on SDMMC. 11643 From David Sidrane. 11644 - STM32 F1-F4 Timer Driver: Change calculation of per- timer pre-scaler 11645 value. Add support for all timers 11646 - STM32 F1-F4: Correct conditional compilation in STM32 timer capture 11647 logic. From Pierre-noel Bouteville 11648 - STM32 F1-F4: Fix STM32 DMA code and configuration for STM32F37X chips. 11649 From Marten Svanfeldt. 11650 - STM32 F1-F4: Fix compilation errors in debug mode of stm32_pwm.c. 11651 From Konstantin Berezenko. 11652 - STM32 F1-F4: Correct the CAN2 RX IRQ number for stm32f10xx chips. 11653 From Konstantin Berezenko. 11654 - STM32 F1-F4: Move backup domain reset to earlier in the 11655 initialization sequence (stm32_rcc.c() in order to avoid disabling 11656 LSE during RTC initialiation. From Alan Carvalho de Assis. 11657 - STM32 F1-F4: When configuring a GPIO via stm32_configgpio() the 11658 function will first set the mode to output and then set the initial 11659 state of the gpio later on. If you have an application with an 11660 externaly pulled-up pin, this would lead to a glitch on the line 11661 that may be dangerous in some applications (e.G. Reset Line for 11662 other chips, etc). This changes sets the output state before 11663 configuring the pin as an output. From Pascal Speck . 11664 - STM32 F7: Apply Pascal Speck's GPIO STM32 change to STM32 L4. 11665 - STM32 L4: Apply Pascal Speck's GPIO STM32 change to STM32 L4. 11666 From Sebastien Lorquet. 11667 - STM32 F7: BUGFIX: PLLs IS2 and SAI P Calculation. From David 11668 Sidrane. 11669 - STM32 L4: STM32 CAN fixes need to be backported to STM32L4 as well. 11670 - STM32 F1-F4 and L4: Writing zero to NVIC_IRQ_ENABLE has no effect. 11671 Disable interrupts with NVIC_IRQ_CLEAR. From Paul Alexander 11672 Patience. 11673 - STM32 F7: STMF7xxx RTC: (1) Remove proxy #defines, (2) Ensure the 11674 LSE(ON) etal are set and remembered in a) A cold start (RTC_MAGIC 11675 invalid) of the RTC, and b) A warm start (RTC_MAGIC valid) of the 11676 RTC but a clock change. The change was needed because in bench 11677 testing a merge of the latest's STM32 53ec3ca (and friends) it 11678 became apparent that the sequence of operation is wrong in the 11679 reset of the Backup Domain in the RCC code. PWR is required before 11680 the Backup Domain can be futzed with. !!!This Code should be tested 11681 on STM32 and if needed rippled to the STM32 families.

From David 11686 Sidrane. 11687 - STM32 L4: Fix incorrect clock setup for LPTIM1. From ziggurat29. 11688 - STM32 F4/L4 RTC ALARM: were enabling interrupts too early in the 11689 power-up sequence, BEFORE the interrupt system was being 11690 initialized. 11691 11692 * STMicro STM32 Boards: 11693 11694 - STM32 board.h: Fix STM32 timer input clock definitions. From David 11695 Sidrane. 11696 11697 * TI Tiva Drivers: 11698 11699 - Bug Fix in tiva_serial.c - UART5, UART6 and UART7 were not being 11700 configured as TTYS0 for printing over serial console. From Shirshak 11701 Sengupta. 11702 11703 * C Library/Header Files: 11704 11705 - include/signal.h: Change type of SIG_ERR, SIG_IGN, ... to 11706 _sa_handler_t. The type void does not work with the IAR toolchain. 11707 From Aleksandr Vyhovanec. 11708 - crc16: fix error. From Paul Alexander Patience. 11709 - strtoul() and strtoull(): Fix errno settings required by function 11710 definition. Resolved Bitbucket Issue #1. From Sebastien Lorquet. 11711 11712 * Build/Configuration System: 11713 11714 - Build system: This change fixes a build problem that only occurs 11715 when reconfiguring from Linux to Windows or vice-versa. It is a 11716 problem that was present but not usually experienced until two 11717 things happened: (1) The pre_config target was added to run before 11718 the menconfig operation and (2) the context target was added before 11719 the pre_config target in order to set up the correct symbolic links 11720 (in the apps/platform directory) needed by the pre_config target. 11721 But then now if you start with a Linux system and run 'make 11722 menuconfig' to switch to Linux, the context target will execute 11723 first and set up POSIX style symbolic links before doing the 11724 menuconfig. Then after the menuconfig, the make will fail on 11725 Windows if you are using a Windows native toolchain because that 11726 native toolchain cannot follow the Cygwin- style symbolic links. 11727 The fix here is to also execute the clean_context AFTER executing 11728 menuconfig. A lot more happens now: It used to be that doing 11729 'make menuconfig' only did the menuconfig operation. Now it does 11730 context, pre_config, menuconfig, clean_context. Not nearly as 11731 snappy as it used to be. 11732 - Need to build the drivers/ directory even it file descriptors are 11733 not supported. There are things in the drivers/ directory that are 11734 still needed (like SYSLOG logic). 11735 - Remove all inclusion of header files from the apps/include 11736 directory from NuttX core logic. There should be no dependency on 11737 logic within NuttX on logic within apps/. This caused a lot of 11738 reshuffling of logic: binfmt pcode support, usbmonitor is now a 11739 kernel thread, TZ/Olson database moved to libc/zoneinfo. 11740 11741 * Application Build/Configuration System: 11742 11743 - Make sure that APPNAME is defined in all Makefiles that generate 11744 applications. From Sebastien Lorquet. 11745 11746 * apps/builtins: 11747 11748 - apps/builtins: exec_builtin was not using the provided open flags. 11749 As a result >> redirection was not working; it was treated the same 11750 as >. 11751 11752 * apps/nshlib: 11753 11754 - apps/nshilib: PS Command: When Priority Inheritance is enabled, the 11755 format of /proc/<PID>/status changes to show both the current 11756 priority and the thread�s base priority. This messes up the format 11757 of cmd_ps. From David Alessio. 11758 11759 * apps/netutils: 11760 11761 - apps/netutils, uIP webserver: Fix a data declaration in a header 11762 file. 11763 11764 * apps/canutils: 11765 11766 - apps/canutils/libuavcan: Fix for recent change to STM32 timer 11767 frequency definiitions. 11768 11769 * apps/examples: 11770 11771 - apps/examples/alarm: ioctl call was clobbering file descriptor. 11772 - apps/examples/can: Some variables were not declared in all required 11773 cases. From Sebastien Lorquet. 11774 - apps/examples/media: media example was intended to take either a 11775 command line argument, or a compiled-in default value from config. 11776 However, the default was ignored, leading to confusing error 11777 messages. From ziggurat29. 11778 11779NuttX-7.18 Release Notes 11780------------------------ 11781 11782The 118th release of NuttX, Version 7.18, was made on October 8, 2016, 11783and is available for download from the Bitbucket.org website. Note 11784that release consists of two tarballs: nuttx-7.18.tar.gz and 11785apps-7.18.tar.gz. These are available from: 11786 11787 https://bitbucket.org/nuttx/nuttx/downloads 11788 https://bitbucket.org/nuttx/apps/downloads 11789 11790Both may be needed (see the top-level nuttx/README.txt file for build 11791information). 11792 11793Additional new features and extended functionality: 11794 11795 * Core OS: 11796 11797 - Add standard adjtime() interface and basic timekeeping support. 11798 Normally used with an NTP client to keep system time in 11799 synchronization. From Max Neklyudov. 11800 - Use the oneshot timer with optional entropy to measure CPU load if 11801 so configured. 11802 11803 * File System and Block and MTD Drivers: 11804 11805 - Add Fujistu MB85RS256B ramtron support. From Beat K�ng. 11806 - SPI-based MTD driver for Macronix MX25L3233F or MX25L6433F. From 11807 Aleksandr Vyhovanec. 11808 11809 * Graphics/Display Drivers: 11810 11811 - SH1106 0.96 OLED module support (SSD1306 compatible) + I2C fixes. 11812 From v01d (phreakuencies). 11813 11814 * Sensor Drivers: 11815 11816 - Add KXTJ9 Accelerometer driver from the Motorola Moto Z MDK. 11817 - Add MFRC522 RFID ISO14443 and Mifare transceiver driver. From Alan 11818 Carvalho de Assis. 11819 - Add driver for the LIS3MDL 3 axis magnetometer. From Alexander 11820 Entinger. 11821 - Add driver for the MLX90393 3 axis magnetometer. From Alexander 11822 Entinger. 11823 - Add driver for the LIS3DSH 3 axis accelerometer. From Alexander 11824 Entinger. 11825 - Add driver for the Bosch BMG160 3 axis gyroscope. From Alexander 11826 Entinger. 11827 - Add support for the Sensixs XEN1210 3D-board. This sensor is used 11828 on NANOSATC-BR2 a Brazillian CUBESAT project. From Alan Carvalho 11829 de Assis. 11830 - Add a new ioctl command (set MAXPOS) for Tiva QEI. From Young. 11831 11832 * Other Common Device Drivers: 11833 11834 - I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h 11835 definitons. Add support for an attach() method that may be used 11836 when any subset of pin interrupts occur. 11837 - I/O Expander Interface: Encode and extend I/O expander options to 11838 include interrupt configuration. 11839 - PCA9555 Driver: Replace the signalling logic with a simple callback 11840 using the new definitons of ioexpander.h. This repartitioning of 11841 functionality is necessary because (1) the I/O expander driver is 11842 the lower-lower part of any driver that uses GPIOs (include the GPIO 11843 driver itself) and should not be interacting directly with the much 11844 higher level application layer. And (2) in order to be compatible 11845 with the GPIO driver (and any arbitrary upper half driver), the 11846 PCA9555 should not directly signal, but should call back into the 11847 upper half. The upper half driver that interacts directly with the 11848 application is the appropriate place to be generating signal. 11849 - Add a skeleton I/O Expander driver (based on the PCA9555 driver). 11850 - Add PCF8574 I/O Expander driver. 11851 - GPIO driver: Add IOCTLs to get the pin type and to unregister a 11852 signal handler. 11853 - Add a GPIO lower-half driver that can be used to register a GPIO 11854 character driver for accessing pins on an I/O expander. 11855 - Add an SPI helper function that encapsulates and manages a sequence 11856 of SPI transfers. 11857 - Add an SPI character driver that will permit access to the SPI bus 11858 for testing purposes. 11859 - Add oneshot timer lower half interface definition. 11860 - Add an upper-half, oneshot timer character driver. 11861 - Add Audio Tone Generator for NuttX. From Alan Carvalho de Assis. 11862 - Add USB host support for composite devices. This feature is not 11863 well tested. 11864 - drivers/ioexpander: Add an (untested) TCA64XX I/O Expander driver 11865 leveraged from Project Ara. 11866 11867 * Simulation Platform: 11868 11869 - Add a simulated I/O Expander driver. 11870 - Add simulator-based test support for apps/examples/gpio. 11871 - Add a configuration useful for testing Mini Basic. 11872 - Add a simulated oneshot lowerhalf driver. 11873 11874 * Atmel SAM3/4 Drivers: 11875 11876 - SAM4CM: Add option to support oneshot timer without free-running 11877 timer. Add oneshot lower half driver. 11878 11879 * Atmel SAMA5 Drivers: 11880 11881 - SAMA5D: Add option to support oneshot timer without free-running 11882 timer. Add oneshot lower half driver. 11883 11884 * Atmel SAMV7 Drivers: 11885 11886 - SAMV71/SAME70: Add option to support oneshot timer without 11887 free-running timer. Add oneshot lower half driver. 11888 - Add support for SAMV7 DACC module. From Piotr Mienkowski. 11889 11890 * NXP Freescale Kinetis Drivers: 11891 11892 - Add support for I2C and RTC. From v01d (phreakuencies). 11893 11894 * NXP Freescale Kinetis Boards: 11895 11896 - Add teensy 3.x I2C support. From v01d (phreakuencies). 11897 11898 * STMicro STM32: 11899 11900 - Add IAR-style STM32F1xx vectors. Tested on STM32F103RB and 11901 STM32F107RC. From Aleksandr Vyhovanec. 11902 11903 * STMicro STM32 Drivers: 11904 11905 - Add timekeeping support for the STM32 tickless mode. From Max 11906 Neklyudov. 11907 - Add a oneshot, lower-half driver for STM32. 11908 - STM32 L4: Add oneshot lower half driver for STM32 L4. 11909 - STM32 L4: Add support for quadrature encoders on STM32L4. Sebastien 11910 Lorquet. 11911 11912 * STMicro STM32 Boards: 11913 11914 - stm32f103-minimum: Add board support to MFRC522 driver. From Alan 11915 Carvalho de Assis. 11916 - Add oneshot board initialization to stm32f103-minimum. From Alan 11917 Carvalho de Assis. 11918 - stm32f103-minimum: Add board configuration to initialize Audio Tone 11919 Generator. From Alan Carvalho de Assis. 11920 - stm32bufferfly2: Add support for the Kamami stm32butterfly2 11921 development board with optional ETH phy. From Michal Lyszczek. 11922 - stm32f103-minimum: Add board config support to SPI LCD module 11923 JLX12864G-086. From Alan Carvalho de Assis. 11924 - stm32l476-mdk: Support basic booting and nsh on Motorola MDK. The 11925 Motorola MDK is based off of an earlier version of NuttX. 11926 This only provides a basic NSH shell. From Jim Wylder. 11927 - STM32 F4 Discovery: Add support for XEN1210 3D-board. From Alan 11928 Carvalho de Assis. 11929 - stm32f103-minimum: Add stm32_bringup support and userled example to 11930 STM32F103 Minimum board. From Alan Carvalho de Assis. 11931 - Add support for qencoders on various nucleo boards. From Sebastien 11932 Lorquet. 11933 - olimex-stm32-e407: Add some networking configurations. From Mateusz 11934 Szafoni. 11935 11936 * TI Tiva Drivers: 11937 11938 - Add tiva PWM lower-half driver implementation. From Young. 11939 - Tiva QEI: Add QEI lower-half driver for Tiva series chip. From 11940 Young. 11941 11942 * C Library/Header Files: 11943 11944 - Separate XorShift128 PRNG from /dev/urandom and make it generally 11945 available. 11946 - Add POSIX type sig_atomic_t. From Sebastien Lorquet. 11947 - Add the difftime() function. The function depends on the toolchain- 11948 dependent CONFIG_HAVE_DOUBLE so is not available on tiny platforms. 11949 From Sebastien Lorquet. 11950 - Add support for remove(). From Sebastien Lorquet. 11951 - Add system() to stdlib.h. Actual implementation is in 11952 apps/system/system. 11953 11954 * Build/Configuration System: 11955 11956 - Rename arch/sh to arch/renesas. 11957 - Remove contactless drivers from drivers/wireless to drivers 11958 contactless. From Sebastien Lorquet. 11959 - Move all modem-related IOCTL commands to a common file to assure 11960 that they will be unique. 11961 11962 * Tools: 11963 11964 - Add sethost.sh. This is a script that you can use to quickly 11965 change the host platform from Linux to Windows/Cygwin. Might save 11966 you a lot of headaches. 11967 11968 * Applications: apps/nshlib: 11969 11970 - Add logic to support an NSH-specific system command. 11971 - Add printf command to NSH, e.g., controlling /dev/userleds from 11972 command line: nsh> printf \x01 > /dev/userleds. From Alan Carvalho 11973 de Assis. 11974 11975 * Platforms: apps/system: 11976 11977 - Port tee command from NetBSD. 11978 - Add a generic system command. Current implentation cannot use 11979 /bin/sh and spawns the custom NSH system command directly. 11980 11981 * Platforms: apps/platform: 11982 11983 - Add C++ support for STM32L476-MDK. 11984 11985 * Platforms: apps/interpreters: 11986 11987 - Add a port of Mini Basic, version 1.0, written by Malcom McLean and 11988 released under the Creative Commons Attribution license. 11989 11990 * Applications: apps/examples: 11991 11992 - Add a simple test of the GPIO driver. 11993 - Add RFID_READUID sample application. From Alan Carvalho de Assis. 11994 - Add Oneshot timer example. 11995 - Add a simple test of the system command. 11996 11997Works-In-Progress: 11998 11999 * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were 12000 introduced in NuttX-7.15. Work has continued on this effort on 12001 forks from the main repositories, albeit with many interruptions. 12002 The completion of this wireless feature will postponed until at 12003 least NuttX-7.19. 12004 12005Bugfixes. Only the most critical bugfixes are listed here (see the 12006ChangeLog for the complete list of bugfixes and for additional, more 12007detailed bugfix information): 12008 12009 * Core OS: 12010 12011 - Explicitly initialize the group tg_exitsem with sem_init(). The 12012 existing logic worked because the correct initialization value is 12013 all zero, but it is better to initialize the semaphore explicitly. 12014 - The TCB nchildren field should not be incremented when pthreads are 12015 created. 12016 - Move fields related to parent/child task relationship out of TCB 12017 into group structure where they belong. Child is a group, not a 12018 thread. 12019 - mq_send() was not setting the errno value on certain failures to 12020 allocate a message. 12021 - Define 'group' even if HAVE_GROUPID is not set. From Mateusz 12022 Szafoni. 12023 - Vector table should have dimension NR_IRQS, not NR_IRQS+1. From 12024 Sagitta Li. 12025 - pthreads: When a pthread is started, there is a small bit 12026 of logic that will run on the thread of execution of the new 12027 pthread. In the case where the new pthread has a lower 12028 priority than the parent thread, then this could cause both the 12029 parent thread and the new pthread to be blocked at the priority of 12030 the lower priority pthread (assuming that CONFIG_PRIORITY_INHERITANCE 12031 is not selected). This change temporarily boosts the priority of the 12032 new pthread to at least the priority of the new pthread to at least 12033 the priority of the parent thread. When that bit of logic has 12034 executed on the thread of execution of the new pthread, it will then 12035 drop to the correct priority (if necessary) before calling into the 12036 new pthread's entry point. 12037 12038 * File System/Block Drivers/MTD Drivers: 12039 12040 - FAT performance improvement. In large files, seeking to a 12041 position from the beginning of the file can be very time consuming. 12042 ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted 12043 time since we are going to seek to the same position. This fix 12044 short-circuits fat_seek() in all cases where we attempt to seek to 12045 current position. Suggested by Nate Weibley. 12046 - MTD: Fixed cloned typos in several FLASH drivers. From Aleksandr 12047 Vyhovanec. 12048 - mount: Corrects a bad assertion noted by Pierre-noel Bouteville. 12049 Also fixes a reference counting problem in an error condition: 12050 When the mountpoint inode is found but is not an appropriate 12051 mountpoint, the reference count on the inode was not being 12052 decremented. 12053 12054 * Common Drivers: 12055 12056 - Various serial drivers: Fix FIONWRITE and add FIONSPACE. All 12057 implementations of FIONWRITE were wrong. FIONWRITE should return 12058 the number of bytes waiting in the outgoing send queue, not the free 12059 space. Rather, FIONSPACE should return the free space in the send 12060 queue. 12061 - Add missing prototype for btn_lower_initialize(). 12062 - Make DAC sample structure packed. From Marc Recht�. 12063 12064 * Networking: 12065 12066 - TCP: tcp_ipvX_bind() not actually using the port selected with 12067 port==0. Also removes duplicate call to pkt_input(). Issues noted 12068 by Pascal Speck. 12069 - drivers/net: NET_TUN=y => NET_MULTIBUFFER=y. From Vladimir 12070 Komendantskiy. 12071 - slip driver: Fix calculations using MSEC_PER_TICK. If 12072 USEC_PER_TICK is less than 1000, then MSEC_PER_TICK will be 12073 zero. It will be inaccurate in any case. 12074 12075 * Atmel SAM3/4 Drivers: 12076 12077 - SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is 12078 configured as input. The value of a GPIO input is only sampled when 12079 the peripheral clock for the port controller the GPIO resides in is 12080 enabled. Therefore we need to enable the clock even when polling a 12081 GPIO. From Wolfgang Reissnegger. 12082 - All SAM Ethernet Drivers: Add support so that the drivers can be 12083 built with CONFIG_NET_MULTIBUFFER=y. 12084 - SAM3/4: Fix GPIO pull-up/down code. Enabling the pull-down resistor 12085 while the pull-up resistor is still enabled is not possible. In this 12086 case, the write of PIO_PPDER for the relevant I/O line is discarded. 12087 Likewise, enabling the pull-up resistor while the pull-down resistor 12088 is still enabled is not possible. In this case, the write of 12089 PIO_PUER for the relevant I/O line is discarded. From Wolfgang 12090 Rei�negger. 12091 12092 * Atmel SAMV7 Drivers: 12093 12094 - All SAM Ethernet Drivers: Add support so that the drivers can be 12095 built with CONFIG_NET_MULTIBUFFER=y. 12096 - SAM GPIO: Apply Wolfgang's change for SAM3/4 to SAMA5 and SAMV7. 12097 12098 * Atmel SAMA5: 12099 12100 - Add missing oneshot max_delay method. 12101 - All SAM Ethernet Drivers: Add support so that the drivers can be 12102 built with CONFIG_NET_MULTIBUFFER=y. 12103 - SAM GPIO: Apply Wolfgang's change for SAM3/4 to SAMA5 and SAMV7. 12104 12105 * NXP Freescale LPC43xx Drivers: 12106 12107 - LPC43xx serial: Fix typos in LPC43 serial driver. Found by Vytautas 12108 Lukenskas. 12109 - LPC43xx Serial: There are some small problems in LPC43xx RS485 mode 12110 configuration. In particular: (1) UART0,2,3 do not have DTR pins 12111 (different from UART1), so, Kconfig needs to be adjusted. (2) 12112 lpc43_uart.c in RS485 mode only configures DIR pin, but doesn't 12113 enable pin output for UART0,2,3. (3) should be option to reverse DIR 12114 control pin output polarity. (4) lpc43xx/chip/lpc43_uart.h doesn't 12115 have USART3 definitions. NOTE: I didn't modified and didn't tested 12116 USART1, as it has different hardware. From Vytautas Lukenskas. 12117 From Vytautas Lukenskas. 12118 12119 * SiLabs EFM32 Drivers: 12120 12121 - EFM32 SPI drivers adopted incompatible conventions (See STM32 for 12122 details of the issue). 12123 12124 * STMicro STM32 Drivers: 12125 12126 - STM32, STM32 L4, and EFM32 SPI drivers adopted incompatible 12127 conventions somewhere along the line. They set the number of bits 12128 to negative when calling SPI_SETBITS which had the magical side- 12129 effect of setting LSB first order of bit transmission. This is not 12130 only a hokey way to pass control information but is supported by no 12131 other SPI drivers. This change three things: (1) It adds 12132 HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the 12133 implementations of SPI_SETBITS in the STM32 and EFM32 drivers so 12134 that negated bit numbers are simply errors and it adds the 12135 SPI_HWFEATURES method that can set the LSB bit order, and 12136 (3) It changes all calls with negative number of bits from all 12137 drivers: The number of bits is now always positive and 12138 SPI_HWFEATURES is called with HWFEAT_LSBFIRST to set the bit order. 12139 - Add missing SPI2 and SPI3 support for STM32F3F3. Add STM32F37XX DMA 12140 channel configuration. For STM32F37XX, SYSCFG_EXTICR_PORTE defined 12141 twice. From Alan Carvalho de Assis. 12142 - STM32: Make stm32_pwr_enablebkp thread safe. From Max Neklyudov. 12143 - Fix bad pllmul values for STM32F1XX connectivity line. STM32F1XX 12144 connectivity line supports only x4, x5, x6, x7, x8, x9 and x6.5 12145 values. From Michal Lyszczek. 12146 - STM32F3 SPI: Fix the number of bit setting for the F3. That and 12147 data packing work differently on the STM32F3 than for other STM32 12148 parts. 12149 - STM32 and STM32 L4: Enabling SPI DMA loses other bits in CR2. 12150 - STM32F3 SPI: Cannot write always 16-bit value to DR register 12151 because of how the F3 implements data packing. 12152 - STM32F411 and STM32F446 map i2c2_sda_4 to different alternate 12153 function numbers. From Konstantin Berezenko. 12154 - STM32 DMA Fix: Change stm32 adc dma callback to send channel 12155 number instead of index. From Konstantin Berezenko. 12156 - STM32 OTGFS device: Fix for lost first word from FIFO 12157 12158 1) Do not overwrite Reserved Bits in GINTSTS (per ref manual)* 12159 2) Acknowledge all pending int on entry to ISR that are Only rc_w1* 12160 3) Do not disable RXFVL* 12161 4) Loop until RXFVL is cleared* 12162 5) Only clear the NAK on the endpoint on the OTGFS_GRXSTSD_PKTSTS_SETUPDONE to not loose the first WORD of FIFO all the data (Bug Fix) 12163 12164 Changed marked *are just driver clean up and ensure ints are not lost. The bug fix is #5 12165 12166 Test case open putty and observer the Set/Get LineCoding. Without this fix #5 the Get will not match the Set, and in fact the data might be skewed by 4 bytes, that are lost from the FIFO if the OTGFS_DOEPCTL0_CNAK bit is set in the OTGFS_GRXSTSD_PKTSTS_SETUPRECVD as opposed to the OTGFS_GRXSTSD_PKTSTS_SETUPDONE 12167 12168 Set Line Coding DATA1: 4B | 00 c2 01 00 00 00 08 | c8 1B 12169 Get Line Coding DATA1: 4B | .. .. .. .. 00 00 08 c8 .. 00 00 07 | 7a 72 12170 12171 From David Sidrane. 12172 - STM32 L4 OTGFS device: Apply stm32 fix to stm32l4. From Sebastien 12173 Lorquet. 12174 - STM32 F7: Remove duplicate call to pkt_input from Ethernet driver. 12175 Issues noted by Pascal Speck. 12176 - STM32 L4: Add support for USART3-USART5. For STM32L4 parts, the 12177 higher number USART ports supported varies. Add the HAVE_USARTx 12178 definitions to the configuration to allow enabling the higher 12179 numbered USART ports. From Jim Wylder. 12180 - STM32 USB: Set USB address to avoid a failed assertion. From 12181 Pierre-noel Bouteville. 12182 - STM32 L4 and L7 USB: Pierre's assertion-avoidance change should 12183 also be applied to STM32 F7 and L4. 12184 - STM32, L4, and F7: Remove GPIO_ETH_RMII_TX_CLK. TX_CLK is not 12185 present in RMII. Mateusz Szafoni. 12186 - STM32 Ethernet: Correct typo in conditional logic. From Neil 12187 Hancock. 12188 - STM32 L4 USB Device: Fixed L4 USB Driver by avoiding SETUPDONE and 12189 EPOUT_SETUP. From David Sidrane. 12190 - STM32 SPI: stm32_modifycr2 should be available on all platforms if 12191 DMA is enabled. 12192 - STM32 DMA2D: fix an error in up_dma2dcreatelayer where an invalid 12193 pointer was returned when a certain underlying function failed. 12194 From Jens Gr�f. 12195 12196 * TI Tiva Drivers: 12197 12198 - Fix two bugs of tiva pwm lower-half driver implementation. From 12199 Young. 12200 - Tiva Ethernet: Needs support for CONFIG_NET_MULTIBUFFER=y. 12201 12202 * C Library/Header Files: 12203 12204 - lib_dumpbuffer() now prints a large on-stack buffer first to avoid 12205 problems when the syslog output is prefixed with time. From 12206 Pierre-noel Bouteville. 12207 - libc/math: This fixes the following libc/math issues: (1) asin[f l]() 12208 use Newton�s method to converge on a solution. But Newton�s method 12209 converges very slowly (> 500,000 iterations) for values of x close to 12210 1.0; and, in the case of asinl(), sometimes fails to converge (loops 12211 forever). The attached patch uses an trig identity for values of 12212 x > sqrt(2). The resultant functions converge in no more than 5 12213 iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions are 12214 based on Chebyshev fitting to a good guess. The problem there�s a 12215 bug in the implementation that causes the functions to blow up with 12216 x near -3.0. This patch fixes that problem. It should be noted that 12217 this method returns the error function erf(x) with fractional error 12218 less than 1.2E-07 and that�s fine for the float version erff(), but 12219 the same method is used for double and long double version which 12220 will yield only slightly better precision. This patch doesn't 12221 address the issue of lower precision for erf() and erfl(). (3) a 12222 faster version of copysignf() for floats is included. From David S. 12223 Alessio. 12224 - strtod() was not returning endptr on error conditions. 12225 - libc/math: floor(), floorf(), and floorl(): Fix logic error. Was 12226 not correctly handling negative integral value. 12227 - isatty() should be prototyped in unstid.h, not termios.h. From 12228 Sebastien Lorquet. 12229 - nxglib: Fix handling of near-horizontal lines of width 1 in 12230 nxgl_splitline(). Missing handling for degenerate condition caused 12231 width 1 lines such as (0, 0) - (100, 10) to have gaps in the 12232 drawing. From Petteri Aimonen. 12233 12234 * Build/Configuration System: 12235 12236 - Top-Level Makefiles: Fix a chicken-and-egg problem. In the menuconfig 12237 target, the context dependency was executed before kconfig-mconf. That 12238 was necessary because the link at apps/platform/board needed to be set 12239 up before creating the apps/Kconfig file. Otherwise, the platform 12240 Kconfig files would not be included. But this introduces the chicken- 12241 and-egg problem in some configurations. In particular: (1) An NX 12242 graphics configuration is used that requires auto-generation of 12243 source files using cpp, (2) the configuration is set for Linux, but 12244 (3) we are running under Cygwin with (4) a Windows native toolchain. 12245 In this case, POSIX-style symbolic links are set up but the Windows 12246 native toolchain cannot follow them. The reason we are running 12247 'make menuconfig' is to change from Linux to Cygwin, but the target 12248 fails. During the context phase, NX runs CPP to generate source files 12249 but that fails because the Windows native toolchain cannot follow 12250 the links. Checkmate. This was fixed by changing all of the make 12251 menuconfig (and related) targets. They no longer depend on context 12252 being run. Instead, they depend only on the dirlinks target. The 12253 dirlinks target only sets up the directory links but does not try 12254 to run all of the context setup; the compiler is never invoked; no 12255 code is autogenerated and things work. 12256 - CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From 12257 Beat K�ng. 12258 12259 * Tools 12260 12261 - tools/refresh.sh: Recent complexities added to apps/ means that 12262 configuration needs the correct Make.defs file in place in order to 12263 configure properly. 12264 - tools/kconfig2html.c: Update to handle absolute paths when sourcing 12265 Kconfig files. 12266 - tools/mkfsdata.pl was still generating the old-style apps/include 12267 inclusion paths. 12268 12269 * Application Build/Configuration System: 12270 12271 - Add DIRLINK and DIRUNLINK tool definitions to apps/Make.defs. 12272 12273 * apps/nshlib: 12274 12275 - Fix FIFO_SIZE vs PIPE_SIZE. 12276 - Fix hex representation of IP address in Kconfig. Noted by Michal 12277 Lyszczek. 12278 - nsh_syscmds.c: missing semicolon. From Mateusz Szafoni. 12279 - In system command, don't try to flush output streams if stdio 12280 buffered I/O is not supported. 12281 12282 * apps/canutils: 12283 12284 - libuavcan: Under certain circumstances, DELIM is not be defined in 12285 Makefile. 12286 - Add definition for APPNAME in apps/canutils/canlib. From Sebastien 12287 Lorquet. 12288 12289 * apps/gpsutils: 12290 12291 - Fix an error minmea. From Aleksandr Vyhovanec. 12292 12293 * apps/examples: 12294 12295 - apps/examples/oneshot: If the requested delay is > max_delay, then 12296 break the delay up into several pieces. 12297 12298NuttX-7.19 Release Notes 12299------------------------ 12300 12301The 119th release of NuttX, Version 7.19, was made on December 26, 2016, 12302and is available for download from the Bitbucket.org website. Note 12303that release consists of two tarballs: nuttx-7.19.tar.gz and 12304apps-7.19.tar.gz. These are available from: 12305 12306 https://bitbucket.org/nuttx/nuttx/downloads 12307 https://bitbucket.org/nuttx/apps/downloads 12308 12309Both may be needed (see the top-level nuttx/README.txt file for build 12310information). 12311 12312Additional new features and extended functionality: 12313 12314 * Core OS: 12315 12316 - sched/semaphore, sched/phread/, libc/semaphore, libc/pthread: Add 12317 pthread_mutexattr_get/set_protocol and non-standard 12318 sem_get/set_protocol. These may use to enable or disable priority 12319 inheritance on a single semaphore. 12320 - Spinlocks: Added capability to provide architecture-specific memory 12321 barriers. 12322 - SMP: Add spin_trylock(). Use this in conditions where other CPUs need 12323 to stopped but we cannot call enter_critical_section(). 12324 - sched note: Extend OS instrumentation to include some SMP events. 12325 Also add spinlock instrumentation; In SMP configurations, add a 12326 filter mask to log only notes from certain CPUs. 12327 - sched note: Permit spinlock and critical section notes in in-memory 12328 buffer iff sched_not_get() interfaces is disabled. 12329 - sched note: Add additional note to see if/when CPU is started in SMP 12330 mode. 12331 - sched note: Record ID enumeration now results on constant values; ID 12332 values do not change with configuration. This makes writing post-processing software much easier. 12333 - boardctl: Add new boardctl() command, BOARDIOC_NX_START, to start the 12334 NX server as a kernel thread. 12335 - pthreads: Add pthread_cleanup_push() and pthread_cleanup_pop(). 12336 - pthreads: Added pthread_setcanceltype() and pthread_testcancel(). 12337 - pthreads: Add support for cancellation points. 12338 - task_delete() now obeys all cancellation point semantics. 12339 - Add task_setcancelstate(), task_setcanceltype(), and 12340 task_testcancel(). These are non-standard interfaces analogous to the 12341 correponding pthread_ interfaces that provide cancellation controls 12342 for tasks. 12343 12344 * Graphics/Display Drivers: 12345 12346 - boardctl: Add new boardctl() command, BOARDIOC_NX_START, to start the 12347 NX server as a kernel thread. 12348 12349 * Networking/Network Drivers: 12350 12351 - Network drivers: Add option to use low-priority work queue to all 12352 Ethernet and MAC level drivers. 12353 - Network Drivers: Adapt all Ethernet (and other MAC) drivers to work 12354 as though CONFIG_NET_MULTIBUFFER were set. Remove all references to 12355 CONFIG_NET_MULTIBUFFER. 12356 - Eliminate CONFIG_NO_NOINTS. There is no longer any support for 12357 interrupt level processing of the network stack. Lots of files changed. 12358 12359 * Other Common Device Drivers: 12360 12361 - Vishay VEML6070: Add Vishay VEML6070 driver. From Alan Carvalho de 12362 Assis. 12363 12364 * ARMv7-A 12365 12366 - ARMv7-A/i.MX6: Add SCU register definitions. Add some controls to 12367 enable SMP cache coherency in SMP mode. Makes no difference, however 12368 -- cache still incoherent on i.MX6. 12369 - ARMv7 GIC: SGIs are non-maskable but go through the same path as 12370 other, maskable interrupts. Added logic to serialize SGI processing 12371 when necessary. 12372 12373 * Atmel SAM3/4: 12374 12375 - SAM3/4: Add SMP support for the dual-core SAM4CM. From Masayuki 12376 Ishikawa. 12377 12378 * Atmel SAM3/4 Drivers: 12379 12380 - Add support for the SAM5CMP-DB board. From Masayuki Ishikawa. 12381 12382 * Atmel SAM3/4 Boards: 12383 12384 - SAM4CMP-DB: Add support for the Atmel SAM4CMP-DB board running in an 12385 SMP configuration. From Masayuki Ishikawa. 12386 - SAM4CMP-DB: Add hooks to auto-mount the procfs file system on startup 12387 in board bring-up logic. 12388 12389 * Atmel SAMV7 Drivers: 12390 12391 - SAMv7: Register the watchdog device at the configured device path 12392 CONFIG_WATCHDOG_DEVPATH vs. hard-coded /dev/wdt. From Frank Benkert. 12393 12394 * Calypso 12395 12396 - Calyps: Remove all Calypso board configurations. Remove Calypso 12397 architecture support and support for Calypso SERCOMM driver. 12398 12399 * Misoc LM32: 12400 12401 - Misoc LM32: Adds basic support for the Misoc procoessors and the LM32 12402 in particular. From Ramtin Amin. 12403 - Misoc LM32: Add signal handling logic. From Ramtin Amin. 12404 - Misoc LM32: Add logic to flush/invalidate caches. From Ramtin Amin. 12405 12406 * Misoc LM32 Drivers: 12407 12408 - Misoc LM32 Serial: Add interrupting Misoc serial driver. From Ramtin 12409 Amin. 12410 - Misoc LM32 Timer: Add timer driver. From Ramtin Amin. 12411 - Misoc LM32: Add Misoc Ethernet driver From Ramtin Amin. 12412 12413 * Misoc LM32 Boards: 12414 12415 - Misoc LM32 Qemu: Board support for testing Misoc LM32 with Qemu. From 12416 Ramtin Amin. 12417 - Misoc LM32 Qemu: Integrate network support into configs/misoc/hello. 12418 From Ramtin Amin. 12419 - Misoc LM32 Qemu: Remove configs/misoc/include/generated directory. I 12420 suppose the intent now is that this is a symbolic link? DANGER! 12421 This means that you cannot compile this code with first generating 12422 these files a providing a symbolic link to this location! There is a 12423 sample directory containing generated sources. This is really only 12424 useful for performing test builds. You really must generate the Misoc 12425 architecture for a real-life build. From Ramtin Amin. 12426 12427 * NXP Freescale i.MX6 Drivers: 12428 12429 - i.MX6: Add an untested SPI driver taken directly from the i.MX1 port. 12430 12431 * NXP Freescale Kinetis: 12432 12433 - Kinetis: Added missing headers. Kinetis broke out SPI to 12434 kinetis/kinetis_spi.h. Broke out DMA to use the modern Nuttx chip 12435 inclusion - still STUBS. Add Kinetis support for ARMV7-M Common 12436 Vector and FPU. Allow CONFIG_ARMV7M_CMNVECTOR, 12437 CONFIG_STACK_COLORATION, CONFIG_ARCH_FPU. Fix i2c driver offset 12438 swapped for value in kinetis_i2c_putreg. From David Sidrane. 12439 12440 * NXP Freescale Kinetis Drivers: 12441 12442 - Kinetis: Add UID Unique ID. From Neil Hancock. 12443 12444 * NXP Freescale Kinetis Boards: 12445 12446 - Freedom-K64F board: Add support for UID Unique ID. From Neil Hancock. 12447 12448 * NXP Freescale LPC17xx Boards: 12449 12450 - Olimex-LPC1766-STK: Enable procfs in NSH configuration. Automount 12451 /proc on startup. 12452 12453 * NXP Freescale LPC43xx Drivers: 12454 12455 - LPC43xx: Add timer driver: From Alan Carvalho de Assis. 12456 - LPC43xx GPDMA driver: The GPDMA block is basically the same as the 12457 LPC17xx. Only the clock configuration is different and LPC43xx has 12458 four different DMA request sources, where LPC17xx has only two. From 12459 Alan Carvalho de Assis. 12460 12461 * NXP Freescale LPC43xx Boards: 12462 12463 - Bambino 200E: Add basic support to Micromint Bambino 200E board. 12464 This includes contributions from Jim Wolfman. From Alan Carvalho de 12465 Assis. 12466 - Bambino 200E: Add support for timer driver. From Alan Carvalho de 12467 Assis. 12468 12469 * RGMP: 12470 12471 - Remove RGMP and RGMP drivers. 12472 12473 * RISC-V: 12474 12475 - RISC-V: Add support for the RISC-V architecture and 12476 configs/nr5m100-nexys4 board. The board support on this is pretty 12477 thin, but it seems like maybe a good idea to get the base RISC-V stuff 12478 in since there are people interested in it. From Ken Pettit. 12479 12480 * STMicro STM32 Drivers: 12481 12482 - STM32 F3: Implemention of the STM32 F37xx SDADC module. There are 12483 also changes to ADC, DAC modules. SDADC has only been tested in DMA 12484 mode and does not support external TIMER triggers. This is a work in 12485 progress. From Marc Recht�. 12486 - STM32 F3: Add PWM driver support for STMF37xx. The changes have been 12487 tested successfuly for TIM4 and TIM17 (different IPs). From Marc 12488 Recht�. 12489 - STM32 F4: Support oversampling by 8 for the STM32 F4. From David 12490 Sidrane. 12491 - STM32 F4: Added Timers 2-5 and control of SAI and I2S PLLs.

ESP32 added. 12532 - Xtensa ESP32: Add EXPERIMENTAL hooks to support lazy Xtensa 12533 co-processor state restore in the future. 12534 - Xtensa ESP32: Basic port is function in both single CPU and dual CPU 12535 SMP configurations. There is an NSH configuration for each CPU 12536 configuration. Outstanding issues include missing clock configuration 12537 logic, missing partition tables to support correct configuration from 12538 FLASH, and some serial driver pin configuration issues. 12539 - Xtensa ESP32: Add stack checking logic. 12540 12541 * Xtensa/ESP32 Boards: 12542 12543 - ESP32 Core v2: Basic support for Expressif ESP32 Core v2 board 12544 added. The initial release includes an NSH and an SMP test 12545 configuration. 12546 - ESP32 Core v2: Add configuration to support linking NuttX for 12547 execution out of IRAM. 12548 - ESP32 Core v2: Automatically mount /proc at start-up. 12549 - ESP32 Core v2: Add an OS test to verify the port. 12550 12551 * C Library/Header Files: 12552 12553 - libc/locale: Add a dummy setlocale() function to avoid drawing the 12554 function from newlib. Add clocale header file. 12555 - include/locale.h: Modify locale.h to add localeconv() and lconv 12556 structure. From Alan Carvalho de Assis. 12557 - libc/locale: Allows c++ code to compile with or without 12558 CONFIG_LIBC_LOCALE and will generate a link error if 12559 CONFIG_LIBC_LOCALE is not defined and setlocale is referenced. With 12560 CONFIG_LIBC_LOCALE defined setlocale will act as if MB string is not 12561 supported and return "C" for POSIX. C and "". From David Sidrane. 12562 - libc/wchar: Add wcslen, wmemchr, wmemcmp, wmemcpy wmemset, btowc, 12563 mbrtowc, mbtowc, wcscmp, wcscoll, and wmemmove to NuttX. From Alan 12564 Carvalho de Assis. 12565 - libc/wctype: Add functions wcrtomb, wcslcpy, wcsxfrm, wctob, wctomb, 12566 wctype, localeconv, strcoll, strxfrm, swctype, towlower, towupper and 12567 wcsftime. Add wctype.h; Move lib_wctype.c to libc/wctype. From Alan 12568 Carvalho de Assis. 12569 - include/ctype.h : Add isblank() macro to ctype.h. From Alan Carvalho 12570 de Assis. 12571 - lic/stdlib: Add strtof() and strtold() as simply a copy of strtod 12572 with types and limits changed. 12573 - sscanf(): Use strtof() instead of strtod() if a short floating point 12574 value was requested. The should help performance with MCUs with 12575 32-bit FPU support with some additional code size. 12576 - sscanf(): Add scansets to the scanf function. Enabled 12577 CONFIG_LIBC_SCANSET option. From Aleksandr Vyhovanec. 12578 - include/inttypes.h: Add architecture-specific inttypes.h. From Paul 12579 A. Patience. 12580 - C Library: Allow option to enable IP address conversions even when 12581 the IP address family is not supported. 12582 12583 * Build/Configuration System: 12584 12585 - The Smoothie project needs to compile C++ inside config/boardname/src/ 12586 to use with High Priority Interruption, then I modified the board 12587 configs Makefile to support it. It works fine for the first time 12588 compilation, but if we execute "touch config/boardname/src/Pin.cxx" 12589 and execute "make" it will not detect that Pin.cxx was modified. I 12590 think there is some other place I should modify, but I didn't find 12591 it. From Alan Carvalho de Assis. 12592 12593 * Tools: 12594 12595 - tools/: Add tools/showsize.sh. 12596 12597 * NSH: apps/nshlib: 12598 12599 - NSH: dd command will show statistics. From Masayuki Ishikawa. 12600 12601 * Applications: apps/system: 12602 12603 - apps/system/sched_note: Extend to include additions to instumentation 12604 for SMP. 12605 - apps/system/sched_note: Add support for spinlock notes. 12606 - apps/system/sched_note: Add support for new scheduler instrumentation. 12607 12608 * Platforms: apps/platform: 12609 12610 - ESP32 Core v2: Add platform support for the ESP32 core v2 board. 12611 - Olimex STM32-p407: Add platform support for the Olimex STM32 P407. 12612 12613 * Graphics: apps/graphics 12614 12615 - graphics/traveler/tcledit and libwld: Add an X11 Tcl/Tk tool that can 12616 be used to edit Traveler world files. 12617 - Graphics: Remove all NX server taks. Instead, call boardctl() to the 12618 NX server kernel thread. 12619 12620 * Applications: apps/examples: 12621 12622 - examples/buttons: Add a new buttons example that uses the button 12623 character driver instead of the architecture buttons directly. From 12624 Alan Carvalho de Assis. 12625 - examples/cctype: Add an example to verify cctype functions. 12626 - Remove RGMP example. 12627 - examples/ostest: Extend the pthread cancellation test to exercise 12628 pthread_cleanup_push() (and pthread_cleanup_pop() indirectly via 12629 pthread_cancel() and pthread_exit(). 12630 - examples/ostest: enhance pthread cancellation test some. 12631 12632Works-In-Progress: 12633 12634 * IEEE802.14.5/6LowPAN. Hooks and framework for this effort were 12635 introduced in NuttX-7.15. Work has continued on this effort on 12636 forks from the main repositories, albeit with many interruptions. 12637 The completion of this wireless feature will postponed until at 12638 least NuttX-7.20. 12639 12640Bugfixes. Only the most critical bugfixes are listed here (see the 12641ChangeLog for the complete list of bugfixes and for additional, more 12642detailed bugfix information): 12643 12644 * Core OS: 12645 12646 - sched/semaphore: Within the OS, when a thread obtains a semaphore 12647 count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is 12648 enabled. If a count is available, then sem_wait() calls 12649 sem_addholder(), otherwise it waited for the semaphore and called 12650 sem_addholder() when it eventually received the count. This caused a 12651 problem when the thread calling sem_wait() was very low priority. 12652 When it received the count, there may be higher priority threads 12653 "hogging" the CPU that prevent the lower priority task from running 12654 and, as a result, the sem_addholder() may be delayed indefinitely. 12655 The fix was to have sem_post() call sem_addholder() just before 12656 restarting the thread waiting for the semaphore count. This problem 12657 was noted by Benix Vincent who also suggested the solution. 12658 - Many files: Make sure that priority inheritance is not enabled for 12659 semaphores whose primary use is signaling (vs locking of resources) by 12660 calling sem_setprotocol(). 12661 - sched/semaphore: sem_trywait() no longer modifies the errno value 12662 UNLESS an error occurs. This allows these functions to be used 12663 internally without clobbering the errno value. From Freddie Chopin. 12664 - sched/clock: Correct clock initialization. The correct range for the 12665 month is 0-11 but is entered as 1-12 in the .config file. Add ranges 12666 to START_YEAR, MONTH, and DAY in sched/Kconfig. 12667 - sched/clock: Correct calculation for the case of Tickless mode with a 12668 32-bit timer. In that case, the calculation was returning millisecond 12669 accuracy. That is not good when the timer accuracy is < 1 msec. From 12670 Rajan Gill. 12671 - Work Queue: When queuing new LP work, don't signal any threads if 12672 they are all busy. From Heesub Shin. 12673 - Work Queue: Signal sent from work_signal() may interrupt the low 12674 priority worker thread that is already running. For example, the 12675 worker thread that is waiting for a semaphore could be woken up by the 12676 signal and break any synchronization assumption as a result. It also 12677 does not make any sense to send signal if it is already running and 12678 busy. This change fixes it. From Heesub Shin. 12679 - Fix DEBUGASSERT() in group_signal.c. From Masayuki Ishikawa. 12680 - Eliminate bad boardctl() commands: Remove all references to 12681 BOARDIOC_PWMSETUP and board_pwm_setup(). Remove all references to 12682 BOARDIOC_ADCSETUP and board_adc_setup(). Remove 12683 BOARDIOC_CAN_INITIALIZE. CAN initialization is now done in the board 12684 initialization logic just like every other device driver. 12685 - pthreads: Fix an error in pthread_mutex_destroy(). An error could 12686 occur while destroying a mutex after a pthread has been canceled while 12687 holding the mutex. 12688 - task_restart: Make sure new task starts with pre-emption disabled and 12689 not in a critical section. 12690 - Enter/leave Critical Sections. Major redeign to 12691 enter/leave_critical_section logic to deal with the case where 12692 interrupts are disabled only on the local CPU. In this case, some 12693 rather complex spinlocks must be used to maintain the critical section 12694 accross all CPUs. 12695 - SMP Critical Sections: Fixes for the SMP case: (1) Change order for 12696 SMP case in enter_critical_section: (1) Disable local interrupts 12697 BEFORE taking spinlock and (2) If SMP is enabled, if any interrupt 12698 handler calls enter_critical_section(), it should take the spinlock. 12699 - SMP wdogs: Wdog timers use a tasking interface that to manipulate 12700 wdogs, and a different interface in the timer interrupt handling logic 12701 to manage wdog expirations. In the single CPU case, this is fine. 12702 Since the tasking level code calls enter_critical_section, interrupts 12703 are disabled and no conflicts can occur. But that may not be the case 12704 in the SMP case. Most architectures do not permit disabling 12705 interrupts on other CPUs so enter_critical_section must work 12706 differently: Locks are required to protect code. this change adds 12707 locking (via enter_critical section) to wdog expiration logic for the 12708 the case if the SMP configuration. 12709 - SMP vfork(): Fix a race condition in the SMP case. Existing logic 12710 depended on the fact that the child would not run until waitpid was 12711 called because the child had the same priority as the parent. BUT in 12712 the SMP case that is not true... the child may run immediately on a 12713 different CPU. 12714 - SMP: This change adds a new internal interfaces and fixes a problem 12715 with three APIs in the SMP configuration. The new internal interface 12716 is sched_cpu_pause(tcb). This function will pause a CPU if the task 12717 associated with 'tcb' is running on that CPU. This allows a different 12718 CPU to modify that OS data stuctures associated with the CPU. When 12719 the other CPU is resumed, those modifications can safely take place. 12720 The three fixes are to handle cases in the SMP configuration where one 12721 CPU does need to make modifications to TCB and data structures on a 12722 task that could be running running on another CPU. Those three cases 12723 are task_delete(), task_restart(), and execution of signal handlers. 12724 In all three cases the solutions is basically the same: (1) Call 12725 sched_cpu_pause(tcb) to pause the CPU on which the task is running, 12726 (2) perform the necessary operations, then (3) call up_cpu_resume() to 12727 restart the paused CPU. 12728 - SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting 12729 for g_cpu_irqlock with interrupts interrupts and CPU0 is waiting for 12730 g_cpu_paused. 12731 - SMP: Enforce this rule: Tasks which are normally restored when 12732 sched_unlock() is called must remain pending (1) if we are in a 12733 critical section, i.e., g_cpu_irqlock is locked , or (2) other CPUs 12734 still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In 12735 those cases, the release of the pending tasks must be deferred until 12736 those conditions are met. 12737 12738 * File System/Block Drivers/MTD Drivers: 12739 12740 - AT24XX EEPROM MTD driver: Added EEPROM timeout. Fromo Aleksandr 12741 Vyhovanec. 12742 - fs/procfs: Fix procfs status for SMP case. 12743 12744 * Graphics/Graphic Drivers: 12745 12746 - Fonts: Correct some default font IDs. From Pierre-Noel Bouteville. 12747 12748 * Common Drivers: 12749 12750 - usbhost/enumerate: Fix possible buffer overwrite. From Janne Rosberg. 12751 - usbhost/composite: Fix compile; missing semicolons. From Jann Rosberg. 12752 - syslog: Fixes required for file syslog output. From Max Kriegleder. 12753 - SPI configuration: Fix Kconfig warning. This change moves the 12754 ARCH_HAVE_SPI options outside the check for SPI. Those options don't 12755 depend on SPI, and Kconfig files in arch/ enable them even if SPI 12756 isn't enabled. Source the driver's Kconfig in drivers/Kconfig only 12757 if support for the driver is enabled prevents us from defining these 12758 ARCH_HAVE options in the driver's Kconfig. We should probably remove 12759 the other checks in drivers/Kconfig and check if the drivers are 12760 enabled only in their Kconfig. From Paul A. Patience. 12761 - drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call. 12762 This calls directly from the timer driver into application code. That 12763 is non-standard, non-portable, and cannot be supported. Instead, add 12764 timer driver hooks to support signal notification of timer 12765 expiration. Signal notification logic added by Sebastien Lorquet. 12766 - All timer lower half drivers. Port Sebastien's changes to all other 12767 implementations of the timer lower half. 12768 - USB MSC Device: Fix length of mode6 sense reply packet. From 12769 Wolfgang Rei�negger. 12770 - USB Composite Host: Fix end offset in usbhost_copyinterface(). From 12771 Janne Rosberg. 12772 - USB CDC/ACM Host: Add CDC_SUBCLASS_ACM and CDC_PROTO_ATM to 12773 supported class and proto. From Janne Rosberg. 12774 - SSD1306: Fix errors in SPI mode configuration. From Gong Darcy. 12775 - CDC/ACM Device Class: uart_ops_s portion of cdcacm will not be 12776 initialized with correct functions if CONFIG_SERIAL_DMA is selected. 12777 12778 * Networking/Network Drivers: 12779 12780 - drivers/net/tun.c: Fix bug in TUN interface driver. From Max Nekludov. 12781 12782 * ARMv7-A: 12783 12784 - ARMv7-A SMP: Add SMP logic to signal handling. 12785 12786 * ARMv7-M: 12787 12788 - ARMv7-M: Fix double allocation of MPU region in mmu.h. 12789 12790 * ARMv7-R: 12791 12792 - ARMv7-R: Fix compilation error. This change fixes compilation errors 12793 on MPU support for ARMv7-R. From Heesub Shin. 12794 - ARMv7-R: fix invalid drbar handling. In ARMv7-R, [31:5] bits of DRBAR 12795 is physical base address and other bits are reserved and SBZ. Thus, 12796 there is no point in passing other than the base address. From Heesub 12797 Shin. 12798 - ARMv7-R: Remove the redundant update on SCTLR. mpu_control() is 12799 invoking cp15_wrsctlr() around SCTLR update redundantly. From Heesub 12800 Shin. 12801 - ARMv7-R: Add new Kconfig entries for D/I-cache. Unlike in ARMv7-A/M, 12802 Kconfig entries for data and instruction caches are currently missing 12803 in ARMv7-R. This change adds those missing Kconfig entries. Actual 12804 implmenetation for those functions will be added in the subsequent 12805 patches. From Heesub Shin. 12806 - ARMv7-R: Add cache handling functions. This change adds functions for 12807 enabling and disabling d/i-caches which were missing for ARMv7-R. 12808 From Heesub Shin. 12809 - ARMv7-R: Fix typo in mpu support. s/ARMV7M/ARMV7R/g. From Heesub Shin. 12810 - ARMv7-R: Fix CPSR corruption after exception handling. A sporadic 12811 hang with consequent crash was observed when booting. It seemed to be 12812 caused by the corrupted or wrong CPSR restored on return from 12813 exception. NuttX restores the context using code like this: msr spsr, 12814 r1. GCC translates this to: msr spsr_fc, r1. As a result, not all 12815 SPSR fields are updated on exception return. This should be: msr 12816 spsr_fsxc, r1. On some evaluation boards, spsr_svc may have totally 12817 invalid value at power-on-reset. As it is not initialized at boot, the 12818 code above may result in the corruption of cpsr and thus unexpected 12819 behavior. From Heesub Shin. 12820 - ARMv7-R: Fix to restore the Thumb flag in CPSR. Thumb flag in CPSR is 12821 not restored back when the context switch occurs while executing thumb 12822 instruction. From Heesub Shin. 12823 12824 * Atmel SAM3/4 Drivers: 12825 12826 - SAM3/4 UDP: Add delay between setting and clearing the endpoint RESET 12827 bit in sam_ep_resume(). We need to add a delay between setting and 12828 clearing the endpoint reset bit in SAM_UDP_RSTEP. Without the delay 12829 the USB controller will (may?) not reset the endpoint. If the 12830 endpoint is not being reset, the Data Toggle (DTGLE) bit will not to 12831 be cleared which will cause the next transaction to fail if DTGLE is 12832 1. If that happens the host will time-out and reset the bus. Adding 12833 this delay may also fix the USBMSC_STALL_RACEWAR in usbmsc_scsi.c, 12834 however this has not been verified yet. From Wolfgang Rei�negger. 12835 - SAM3/4: Remove unused 'halted' flag from UDP driver. From Wolfgang 12836 Rei�negger. 12837 - SAM3/4: Remove 'stalled' flag from the UDP driver. This flag is not 12838 necessary because the state of the endpoint can be determined using 12839 'epstate' instead. From Wolfgang Rei�negger. 12840 12841 * Atmel SAM3/4 Boards: 12842 12843 - SAM4S Xplained Pro: Configuration uses old, improper timer interface. 12844 CONFIG_TIMER disabled in configuration. Remove obsolete timer 12845 initialization logic. 12846 12847 * Atmel SAMV7 Drivers: 12848 12849 - SAMv7 USBDEVHS: A problem occurred with the SAMV7 USBDEVHS driver if 12850 the USB cable is unplugged while a large amount of data is send over 12851 an IN endpoint using DMA. If the USB cable is plugged in again after a 12852 few seconds it is not possible to send data over this IN endpoint 12853 again, all other endpoints work as expected. The problem occurs 12854 because if the USB cable is unplugged while an DMA transfer is in 12855 flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL 12856 is left in an undefined state. The problem was fixed the problem by 12857 resetting the register SAM_USBHS_DEVDMACTRL to a known state. 12858 Additionally all pending interrupts are cleared. From Stefan Kolb. 12859 - SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to 12860 CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node 12861 acknowledges the message sent. This will also occur if the device is 12862 not connected to the can-bus. The CAN-Standard declares, that the Chip 12863 has to retry a given message as long as it is not sent successfully 12864 (or it is not cancelled by the application). Every time the chip tries 12865 to resend the message an Acknowledge-Error-Interrupt is generated. At 12866 high baud rates this can lead in extremely high CPU load just for 12867 handling the interrupts (and possibly the error handling in the 12868 application). To prevent this Interrupt-Flooding we disable the ACKE 12869 once it is seen as long we didn't transfer at least one message 12870 successfully. From Frank Benkert. 12871 - SAMV7 MCAN: Make delete_filter functions more robust. From Frank 12872 Benkert. 12873 12874 * Atmel SAMA5 Drivers: 12875 12876 - SAMA5 PWM: Driver does not build when executing from SDRAM before 12877 board frequencies are not constant. Rather, the bootloader configures 12878 the clocking and we must derive the clocking from the MCK left by the 12879 bootloader. This means lots more computations. This is untested on 12880 initial change because I don't have a good PWM test setup right now. 12881 12882 * Misoc LM32: 12883 12884 - Misoc LM32: Corrects a bug that never occured in qemu on simulation or 12885 real fpga. The error was that the r1 register was being modified out 12886 of context switching and not restoring it. From Ramtin Amin 12887 12888 * NXP Freescale i.MX6: 12889 12890 - i.MX6 interrupt handling: Additional logic needed to handle nested 12891 interrupts when an interrupt stack is used. Nesting can occur because 12892 SGI interrupts are non-maskable. 12893 12894 * NXP Freescale LPC43xx Drivers: 12895 12896 - LPC43xx serial: Fix a typo in ioctl TIOCSRS485 ioctl. From Vytautas 12897 Lukenskas. 12898 - LPC43xx serial: Restore RS485 mode on serial port open (if RS485 is 12899 enabled via menuconfig). From Vytautas Lukenskas. 12900 - LPC43xx SD/MMC: Correct some definitions on SMMC control register in 12901 lpc43_sdmmc.h. From Alan Carvalho de Assis. 12902 - LPC43xx SD card: Correct pin configuration options needed for SD card 12903 pins. From Alan Carvalho de Assis. 12904 12905 * SiLabs EFM32: 12906 12907 - EFM32: Fix a compilation error. From Pierre-noel Bouteville. 12908 12909 * STMicro STM32 Drivers: 12910 12911 - STM32 CHxN channels are always outputs. From Sebastien Lorquet. 12912 - STM32 DAC: Fix shift value whenever there are is a DAC2 and, hence, 12913 up to three interfaces. From Marc Recht�. 12914 - STM32 F1: Add TIM8 to STM32F103V pinmap. From Maciej W�jcik. 12915 - STM32 F1: Fix for F1 RTC Clock, tested on F103. From Maciej W�jcik. 12916 - STM32 F3: STM32F303xB and STM32F303xC chips have 4 ADCs. From Paul 12917 A. Patience. 12918 - STM32 F4: A new implementation of the STM32 F4 I2C bottom half. The 12919 common I2C as this did not handled correctly in the current 12920 implementation (see also https://github.com/PX4/NuttX/issues/54). The 12921 changes almost exclusively affect the ISR. From Max Kriegleder. 12922 - STM32 F4 OTGHS Host: If STM32F446 increase number of channels to 12923 16. From Janne Rosberg. 12924 - STM32 F4: I think, that Size is (highest address+1 - Base address). 12925 Base address has been removed and if address+count >= size we are 12926 outside of the Flash. From David Sidrane. 12927 - STM32 F4: Fix ADC compilation error when DMA isn't enabled. From Paul 12928 A. Patience. 12929 - STM32 F4: STM32F427 was rebooting. Over reached family. From David 12930 Sidrane. 12931 - STM32 F4: Added STM32F469 RAM size and deliberated STM32F446 size. 12932 From David Sidrane. 12933 - STM32 F4: Typo in stm32f76xxxx_pinmap.h edited online with 12934 Bitbucket. From David Sidrane. 12935 - STM32 F7: stm32_i2c.c Dejavu. Fixes a bug previously found in the 12936 F4. From David Sidrane. 12937 - STM32 F7: OTGDEV fixed typo. From David Sidrane. 12938 - STM32 F7: Fix to SPI-Master driver. Without this the chip select 12939 decoding feature will not work properly. From Michael Spahlinger. 12940 - STM32 F7: STM32F7 SD/MMC driver depends on CONFIG_SDIO_DMA which is 12941 only defined in stm32/Kconfig. Changed to CONFIG_STM32F7_SDMMC_DMA 12942 and defined in stm32f7/Kconfig. 12943 - STM32 F7: Fix some STM32F7 copy paste errors. From David Sidrane. 12944 - STM32 L4: Complementary PWM outputs on STM32L4" (1) too many 12945 parentheses when calculating max chan count and (2) channel 4 does not 12946 have a complementary output. From Sebastien Lorquet. 12947 - STM32 L4: Fix I2C devices RCC registers. From Sebastien Lorquet. 12948 - STM32 L4: Enable and renaming for 32l4 UARTs 4 and 5. From Sebastien 12949 Lorquet. 12950 - STM32 L4: Change the way to configure quadrature encoder prescalers. 12951 From Sebastien Lorquet. 12952 - STM32 L4: Correct USART1/2 definitions. Use default mbed UART4 12953 settings. From Sebastien Lorquet. 12954 12955 * STMicro STM32 Boards: 12956 12957 - STM32F103 Minimum: Fix Timers 2 to 7 clock frequencies. From Alan 12958 Carvalho de Assis. 12959 - Nucleo-F303RE: Remove duplicate setting from board.h. From Marc 12960 Recht�. 12961 - Nucleo F303RE: Various fixes to get the ADC configuration building 12962 again after PR. Refresh all configurations. 12963 - Nucleo L476RG: Add better selection of timer. 12964 12965 * TI Tiva Boards: 12966 12967 - DK-TM4C129x: Typo fix. From Wolfgang Rei�negger. 12968 12969 * Xtensa ESP32: 12970 12971 - ESP32 core v2: Flush the UART TX buffer in the esp32 serial shutdown 12972 routine. The ROM bootloader does not flush the FIFO before handing 12973 over to user code, so some of this output is not currently seen when 12974 the UART is reconfigured in early stages of startup. From Angus 12975 Gratton. 12976 - Xtensa ESP32: Corrects a problem with dispatching to signal 12977 handlers: Cannot vector directly to the signal handling function as 12978 in other ABIs under the Xtensa Window ABI. In that case, we need to 12979 go through a tiny hook when performs the correct window call (call4) 12980 otherwise registers will be scrambled in the signal handler. 12981 12982 * Xtensa ESP32 Boards: 12983 12984 - ESP32 core v2: Changes the openocd config file's default flash 12985 voltage from 1.8V to 3.3V. This is not necessary right now, but may 12986 save some hard-to-debug moments down the track (3.3V-only flash 12987 running at 1.8V often half-works and does weird things...). From 12988 Angus Gratton. 12989 12990 * C Library/Header Files: 12991 12992 - libc/stdio: Fixes sscanf() %sn where strlen(data) < n. From David 12993 Sidrane. 12994 - libc/stdio: Include wchar.h in lib_libvsprintf.c to fix compilation 12995 error. From Alan Carvalho de Assis. 12996 - include/sys/time.h: timersub macro modified per recommendations of 12997 phreakuencies. 12998 - include/ctype.h and cxx/cctype: Implement ctype.h functions as inline 12999 if possible. cctype can then properly select namespace. 13000 - include/: Fix a number of header files with mismatched 'extern C {' 13001 and '}'. 13002 - libc/unisted: Change brings strtol() and related functions more 13003 conformant with POSIX. Corner cases like strtol(-2147483648, NULL, 13004 10) now pass clang -fsanitize=integer without warnings. From Juha 13005 Niskanen. 13006 - libc/unistd: sleep() was returning remaining nanoseconds (kind of), 13007 instead the remaining seconds. From Eunbong Song. 13008 - termios.h: Fix CRTSCTS define to include input and output flow. From 13009 Lorenz Meier. 13010 13011 * Build/Configuration System: 13012 13013 - configs/*/defconfig: The buttons example was changed to archbuttons. 13014 As a result all of the button configurations are broken and need some 13015 renaming in the defconfig files. Noted by Frank Berkert. 13016 - config/*/defconfgs: More fallout from name change of 13017 apps/examples/buttons to archbuttons. 13018 - configs: All QE encoder files. Last change made timer hard-coded to 13019 3. Make configurable. 13020 - configs: Remove all traces of the no-longer existent ARCHBUTTONS 13021 example. Remove all button configurations that depended on the 13022 obsoleted ARCHBUTTON example. 13023 - minnsh Configurations: Remove minnsh configurations and support 13024 logic: up_getc() and lowinstream. This was an interesting exercise 13025 to see just how small you could get NuttX, but otherwise it was not 13026 useful: (1) the NSH code violated the OS interface layer by callup 13027 up_getc() and up_putc() directly, and (2) while waiting for character 13028 input, NSH would call up_getc() which would hog all of the CPU. Not a 13029 reasonable solution other than as a proof of concept. 13030 13031 * Application Build/Configuration System: 13032 13033 - Make.defs: Using wrong link script if native window tool used with 13034 Cygwin. 13035 13036 * apps/platform: 13037 13038 - ESP32 Core v2 Platform: Fix some naming that prevented building the 13039 C++ support. 13040 13041 * apps/nshlib: 13042 13043 - NSH Library: nsh_getdirpath(), use snprint instead of sprintf to 13044 avoid possibility of buffer overrun. Noted by Chung Hwan Kim. 13045 13046 * apps/system: 13047 13048 - Remove std_readline(). This called up_getc() and up_putc() directly, 13049 violating the POSIX OS interface. 13050 13051 * apps/netutils: 13052 13053 - FTPD: Fixed bug that didn't free ftpd ressources on exit. From Pascal 13054 Speck. 13055 - NTP client: Fix missing left parenthesis. From Pierre-Noel Bouteville. 13056 - cJSON: Import patch to fix:cJSON_PrintUnformatted() behaves unexpected 13057 if an empty array shall be printed to text. from Jerome Lang 13058 2012-04-19. From Pierre-Noel Bouteville. 13059 - esp8266 update cosmetic and many bug fix. From Pierre-Noel Bouteville. 13060 - FTPD: Fix bug un ftpd file or socket may be not closed. From 13061 Pierre-Noel Bouteville. 13062 13063 * apps/modbus: 13064 13065 - Modbus Master is missing many files and doesn't compile at all. More 13066 details in 13067 https://groups.yahoo.com/neo/groups/nuttx/conversations/topics/13734. 13068 From Vytautas Lukenskas. 13069 13070 * apps/examples: 13071 13072 - The examples/qencoder app was trying to init the encoder by a direct 13073 call into the board, cheating in a local header to declare the 13074 normally unavailable function prototype. From Sebastien Lorquet. 13075 - apps/examples/timer: Should detach signal handler before exiting. 13076 - examples/qencode: The examples/qencoder app was trying to init the 13077 encoder by a direct call into the board, cheating in a local header to 13078 declare the normally unavailable function prototype. From Sebastien 13079 Lorquet. 13080 - apps/examples/archbuttons: Removed becaue it violates OS interface 13081 principles. 13082 - examples/adc, pwm, can: Remove all usage of BOARDIOC_ADCTEST_SETUP, 13083 BIOARDIOC_PWMSETUP. Remove BOARDIOC_CAN_INITIALIZE. CAN 13084 initialization is now done in the board initialization logic just like 13085 every other device driver. 13086 - examples/ostest: Add some delays to the pthread cancellation test. 13087 With deferred cancellation enabled, things happen more asynchronously. 13088 13089NuttX-7.20 Release Notes 13090------------------------ 13091 13092The 120th release of NuttX, Version 7.20, was made on March 8, 2017, 13093and is available for download from the Bitbucket.org website. Note 13094that release consists of two tarballs: nuttx-7.20.tar.gz and 13095apps-7.20.tar.gz. These are available from: 13096 13097 https://bitbucket.org/nuttx/nuttx/downloads 13098 https://bitbucket.org/nuttx/apps/downloads 13099 13100Both may be needed (see the top-level nuttx/README.txt file for build 13101information). 13102 13103Additional new features and extended functionality: 13104 13105 * Core OS: 13106 13107 - Kernel Modules: Module initializer may now return a symbol table. 13108 - Modules: Extend the module interface so that we can access symbols 13109 exported by the module. 13110 - Shared Libraries: In the FLAT build mode, kernel modules may be 13111 used to provide minimal shared library functionality. 13112 - Modules/Shared Libraries: Add support for dependencies between 13113 modules. 13114 - Module Library: Add build a configuration logic for a shared module 13115 library. 13116 - Shared Libraries: Implement module based shared libraries for the 13117 PROTECTED mode build. 13118 - Interrupt handling: irq_attach() now includes an argument of type 13119 xcpt_t that retained with the handler address. That argument is 13120 then provided to the interrupt handler when the interrupt occurs. 13121 The common parameter passing replaces the ad hoc parmater passing 13122 implemented in current drivers. From Mark Schulte. 13123 - Adapt many drivers to utilize the IRQ argument feature. 13124 - All functions that used to return an xcpt_t old handler value, now 13125 return an int error code. The oldhandler value is no longer useful 13126 with the recent changes to the interrupt argument passing. Some of 13127 the functions effected include board_button_irq(), arch_phy_irq(), 13128 STM32 EXTI functions (Alarm, COMP, PVD), GPIO interrupt logic like 13129 kinetis_pinirq(), stm32_gpiosetevent(), and others. 13130 - IRQ subsystem: Add support for smaller interrupt tables as 13131 described at 13132 http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors . This 13133 is partially the work of Mark Schulte. 13134 13135 * File Systems/Block and MTD Drivers 13136 13137 - Pseudo File System: Add support for soft links in the top-level 13138 pseudo file system. 13139 - Soft links: Add an implementation of readlink(). 13140 - Add fstat() support. Implement fstat() method in binfs, romfs, 13141 unionfs, tmpfs, nxffs, nfx, hostfs, procfs, and smartfs. 13142 - fstat: Add fstat() support to FAT. From Alan Carvalho de Assis. 13143 13144 * Graphics/Display Drivers: 13145 13146 - Fonts: Add support for Tom Thumb small mono-space font. From Alan 13147 Carvalho de Assis. 13148 - Graphics: Separated of font cache from graphics/nxterm. Now in 13149 libnx/nxfronts where it can be shared with other grapics 13150 applications. 13151 13152 * Networking/Network Drivers: 13153 13154 - Ethernet drivers: Add framework for serialization in the case where 13155 multiple low-priority work queues are used. 13156 13157 * Other Common Device Drivers: 13158 13159 - Add capabilities() method to SDIO interface. Remove 13160 CONFIG_SDIO_WIDTH_D1_ONLY. That should not be a global propertie, 13161 but rather a capability/limitation of single slot when there may be 13162 multiple slots. 13163 - Removed dmasupported() method from the SDIO interface. That is now 13164 a bit in the capability set. 13165 - drivers/sensors: Add driver for the ST L3GD20 3 axis gyro. From 13166 raiden00. 13167 13168 * Atmel SAM3/4: 13169 13170 - SAM3/4: Add support for ATSAM4S4C.

Refactor 13191 implementation. From David Sidrane. 13192 13193 * NXP Freescale Kinetis Drivers: 13194 13195 - Kinetis Ethernet: Kinetis Support RMII clock source select. This 13196 defined the RMII clock source select bits and allows the selection 13197 to be made via Kconfig. From David Sidrane. Freedom-K66F uses 13198 ENET_1588_CLKIN as RMII clock 13199 - Kinetis Serial: Added configurable 1|2 stop bits. 13200 HAVE_SERIAL_CONSOLE -> HAVE_UART_CONSOLE to be consistent with 13201 HAVE_LPUART_CONSOLE naming. From David Sidrane. 13202 - Kinetis LPserial: Add LPUART serial driver and Clock 13203 configuartaion to freedom-k66f board. From David Sidrane. 13204 - Kinetis USB device: Refactor clocking in kinetis_usbdev.

From Alan Carvalho de 13218 Assis. 13219 13220 * STMicro STM32: 13221 13222 - STM32 F7: Allow board to configure HSE clock in bypass-mode. This 13223 is needed to enable HSE with Nucleo-F746ZG board. From Jussi 13224 Kivilinna. 13225 - STM32 F7: stm32_allocateheap: allow use DTCM memory for heap. 13226 STM32F7 has up to 128KiB of DTCM memory that is currently left 13227 unused. This change adds DTCM to main heap if 13228 CONFIG_STM32F7_DTCMEXCLUDE is not enabled. From Jussi Kivilinna. 13229 - Add basic support for the STM32F334. From Mateusz Szafoni. 13230 - STM32F33XX DAC, OPAMP, COMP, ADC, HRTIM headers.

From 13266 Aleksandr Vyhovanec. 13267 - Math library: Leverage optimized ARMv8-M functions from BSD license 13268 ARM file. 13269 - Shared libraries: Add a non-standard dllfnc.h function to set the 13270 symbol table. 13271 - C Library: Add a support for setvbuf(). This is a collaborative 13272 effort. Alan Carvalho de Assis did the initial prototype. 13273 - C Library: Add setbuf() which is a trivial wrapper around setvbuf(). 13274 - C library: Add swab(). 13275 - C library: Add strtoimax and strtoumax. 13276 - C library: Add ffs(), rindex(), an index(). Add strings.h. Move 13277 strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they 13278 belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are 13279 legacy functions; the contemporary counterparts should be used 13280 instead. 13281 - C library: Add fstatfs(). 13282 - Update cwchar. Add cwctype. 13283 13284 * Build/Configuration System: 13285 13286 - Add configuration support for builds with Ubuntu under Windows 10. 13287 13288 * Tools: 13289 13290 - tools/noteinfo.c: A hack tool that I use to analyze some sched_note 13291 output. Needs a home and may be useful to others. 13292 - tools/mkconfig.c: Add logic to keep all of the buffering options in 13293 sync. 13294 13295 * NSH: apps/nshlib: 13296 13297 - NSH: Add support for the 'ln' command. 13298 - NSH ls command: if node is a symobolic link, use readlink() to get 13299 and the display the target of the symblic link. 13300 - NSH: Add readlink command. 13301 13302 * Applications: apps/examples: 13303 13304 - apps/examples/nxtext: Make line spacing configurable. 13305 - apps/system/zmodem/host/nuttx/compiler.h synchronized with 13306 nuttx/nuttx/include/nuttx/compiler.h.

Hooks and framework for this effort were 13315 introduced in NuttX-7.15. Work has continued on this effort on 13316 forks from the main repositories, albeit with many interruptions. 13317 The completion of this wireless feature will postponed until at 13318 least NuttX-7.21. 13319 13320Bugfixes. Only the most critical bugfixes are listed here (see the 13321ChangeLog for the complete list of bugfixes and for additional, more 13322detailed bugfix information): 13323 13324 * Core OS: 13325 13326 - SMP: There were certain conditions that we must avoid by preventing 13327 the release of the pending tasks while withn a critical section. 13328 But this logic was incomplete; there was no logic to prevent other 13329 CPUs from adding new, running tasks while on CPU is in a critical 13330 section. This commit corrects this. This is matching logic in 13331 sched_addreadytorun to avoid starting new tasks within the critical 13332 section (unless the CPU is the holder of the lock). The holder of 13333 the IRQ lock must be permitted to do whatever it needs to do. 13334 - SMP: Make checks for CPU lock set more robust. There are certain 13335 conditions early in initialization on during interrupt handling 13336 where things need to be done a little differently. 13337 - sched_cpulocked: Avoid use of spinlock. That has been reported to 13338 cause a deadlock (2016-12-28). 13339 - SMP: Fix a gap where we may try to make modifications to the task 13340 lists without being in a critical sections. That permits 13341 concurrent access to the tasks lists and many subtle problems. 13342 This fix just remains in the critical section throughout the 13343 operation (and possible until the task is restore in the event of a 13344 context switch). Makes a big difference in stability. 13345 - SMP: Fix an error in critical section logic when performing a 13346 context switch from an interrupt handler. The g_cpu_irqset bit was 13347 not being set for the CPU so other CPUs did not know about the 13348 critical section. 13349 - SMP Signals: Fix some SMP signal delivery logic. Was not handling 13350 some critical sections correctly and was missing logic to signal 13351 tasks running on other CPUs. 13352 - SMP: Fix timer related issues: Round robin and sporadic 13353 scheduling were only being performed for tasks running on the CPU 13354 that processes the system timer interrupt. Similary, CPU load 13355 measurements were only be processed for running on the CPU that 13356 receives the sampling interrupt. 13357 - sched_note: Fix spinlock instrumentation. From Masayuki Ishikawa. 13358 - In all implementations of _exit(), use enter_critical_section() vs. 13359 disabling local interrupts. 13360 - sigtimedwait: When timer expires, up_unblock_task() is called. 13361 This is okay in the single CPU case because interrupts are disable 13362 in the timer interrupt handler. But it is insufficient in the SMP 13363 case. enter_ and leave_critical_section() must be called in order 13364 to manage spinlocks correctly. 13365 - Fix a compile error: in sched_cpuload.c:Line136, the variables ts 13366 and secs are not defined if CONFIG_CPULOAD_ONESHOT_ENTROPY = 0. 13367 However, these variables are used regardless of 13368 CONFIG_CPULOAD_ONESHOT_ENTROPY at lines~180:onwards. From Rajan Gill. 13369 - CPU load: Correct computation of the nominal period to use when the 13370 source is a oneshot timer. 13371 - Cancellation points: Fix some backward logic in conditional 13372 compilation. 13373 - Remove an unused variable when calling sigwaitinfo() and 13374 sigtimedwait(). From Masayuki Ishikawa. 13375 13376 * File System/Block and MTD Drivers: 13377 13378 - procfs: Correct to snprintf-related errors in fs_procfsproc.c. 13379 Resolves issue #24. 13380 - Add logic to VFS rename: If target of rename exists and is a 13381 directory, then the source file should be moved 'under' the target 13382 directory. POSIX also requires that if the target is a file, then 13383 that old file must be deleted. 13384 - Fix open() a block device with 13385 CONFIG_DISABLE_PSEUDOFS_OPERATIONS=y. From Masayuki Ishikawa. 13386 - File System: Don't build block driver proxy if PSEUDOFS_OPERATIONS 13387 are disabled. 13388 - sendfile(): Fix error introduced with commit 13389 ff73be870e38959b0aaee5961dc47b4b58dc2d86. Noted by Maciej W�jcik. 13390 13391 * Graphics/Graphic Drivers: 13392 13393 - NxWM configurations. If using a 7-bit character set, then the 13394 cursor character cannot be 137 (graphic block). Use 95 13395 (underscore) instead. 13396 - NX server: Correct message queue names. Should not be at /dev, 13397 but rather relative to /var/mqueue. 13398 13399 * Common Drivers: 13400 13401 - MMCSD_SDIO: Only wait for card ejected if card detection is 13402 supported. From Alan Carvalho de Assis. 13403 - Typos withim mtd/ with Macronix MX25L. In 13404 NuttX/drivers/mtd/Make.defs letters X between M and 25 are 13405 missing. Noted by Oleg Evseev. 13406 - USBMSC: Always set LUN readonly flag. From Wolfgang Rei�negger. 13407 - drivers/lcd: ssd1306_configspi() must have global scope. 13408 - MMC/SD SDIO: Some drivers need to start DMA before sending CMD24 13409 and some AFTER. From Alan Carvalho de Assis. 13410 - drivers/tone.c: Handle configuration with multiple PWM channels. 13411 This resolves issue #30: Audio Tone Generator and PWM Multiple 13412 Output Channel options. 13413 - drivers/tone.c: 50% duty needs to be expressed a a fixed precision 13414 number. 13415 - drivers/spi/Kconfig: There is too much SPI in the configuration 13416 menu; SPI Driver Support menu is empty. From Maciej W�jcik. 13417 - option to enable Memory Card debug output was hidden with SD cards 13418 connected through SPI. From Maciej W�jcik. 13419 - usbhost_cdcacm: fix tx outbuffer overflow and remove now invalid 13420 assert. From Janne Rosberg. 13421 13422 * Networking/Network Drivers: 13423 13424 - Networking: Fixed some issues that prevented IPv6 from working with 13425 IPv4 enabled. From Pascal Speck. 13426 - Networking: fixed a nullptr-dereference on iob_clone. From Pascal 13427 Speck. 13428 - Ethernet: Need two work structures (minimum) in all Ethernet 13429 drivers so that pending poll work is not lost when an interrupt 13430 occurs. 13431 13432 * ARMv7-R: 13433 13434 - I found an issue inside the cp15_coherent_dcache function: The 13435 "mcr CP15_BPIALLIS(r0)" should only be used with SMP 13436 configurationa. In non-SMP configuration this instruction could 13437 become undefined. From Manohara HK. 13438 13439 * Atmel SAM3/4 Drivers: 13440 13441 - SAM3/4: GPIO bit numbering typo fixes. From Wolfgang Rei�negger. 13442 13443 * Atmel SAM3/4 Boards: 13444 13445 - Add missing sched_note_*() calls in sam4cm SMP functions. 13446 13447 * NXP/Freescale Kinetis: 13448 13449 - Kinetis: Fixed wrong MCG VDIV calculation on new NXP K60. From 13450 Maciej Skrzypek. 13451 - Kinetis: Need to set HAVE_UART_DEVICE when UART4 is selected. From 13452 Maciej Skrzypek. 13453 - Kinetis MCG: Wrong FRDIV set in MCG_C1. From Maciej Skrzypek. 13454 13455 * NXP/Freescale Kinetis Drivers: 13456 13457 - Kinetis Serial: Fixed compile error when UART5 is selected. From 13458 Maciej Skrzypek. 13459 - Kinetis SDHC - Enable clock after selected. From David Sidrane. 13460 - Kinetis: Correct some SPI and I2C configuration issues. From 13461 David Sidrane. 13462 - Kinetis Ethernet: Add #define for number of loops for auto 13463 negotiation to complete. From Marc Recht�. 13464 - Kinetis Werial: Fixed up_rxint - did not disable the RX 13465 interuppts. There was an OR where and AND NOT was needed. From 13466 David Sidrane. 13467 13468 * NXP/Freescale LPC43xx: 13469 13470 - LPC43 pinset definitions: Add more 1 bit to pinset to reach 13471 SFSCLK0-SFSCLK3. Remove PINCONFIG_DIGITAL. From Alan Carvalho de 13472 Assis. 13473 13474 * NXP/Freescale LPC43xx Drivers: 13475 13476 - LPC43 serial: Correct conditional logic that selects /dev/ttySN. 13477 Problem noted by Alan Carvalho de Assis. 13478 13479 * NXP/Freescale i.MX6: 13480 13481 - i.MX6: Fix clearing GPT status register. From Masayuki Ishikawa. 13482 13483 * STMicro STM32: 13484 13485 - STM32, STM32L4 Oneshot: Fix logic so that it can support multiple 13486 oneshot timers. 13487 - STM32 F7: Added missing ARCH_HAVE_RESET for F7. From David Sidrane. 13488 - STM32: Add missing STM32_BKP_BASE. From David Sidrane. 13489 - STM32 and STM32F7: Fixes the BKP reference counter issue. From 13490 David Sidrane. 13491 13492 * STMicro STM32 Drivers: 13493 13494 - Fix for SAMv7 SPI: DLYBS value was calculated, but never written to 13495 any registers. This led to incorrect timings on the bus. From 13496 Michael Spahlinger. 13497 - STM32 QEncoder: Fix QEncoder driver, based on STM32L4 driver. From 13498 Alan Carvalho de Assis. 13499 - STM32 QEncoder: Enable clocking to the timer on QE setup; disable 13500 clock on QE teardown. 13501 - STM32 Ethernet: Need two work structures so that pending poll work 13502 is not lost when an interrupt occurs. This change has also been 13503 ported to all all other effected Ethernet drivers. 13504 - STM32 OTGHS host: stm32_in_transfer() fails and returns NAK if a 13505 short transfer is received. This causes problems from class 13506 drivers like CDC/ACM where short packets are expected. In those 13507 protocols, any transfer may be terminated by sending short or NUL 13508 packet. From Janne Rosberg. Adapted Janne Rosberg's patch to 13509 STM32 OTGHS host to OTGFS host, and to similar USB host 13510 implementations for STM32 L4 and F7. 13511 13512 * STMicro STM32 Boards: 13513 13514 - STM32F4 Discovery: Fix issues with QEncoder support. From Alan 13515 Carvalho de Assis. 13516 13517 * C Library/Header Files: 13518 13519 - Add debug assertion in libdtoa to catch attempts to use floating 13520 point output formats from within an interrupt handler. That will 13521 cause assertions or crashes downstream because __dtoa will attempt 13522 to allocate memory. From Pierre-noel Bouteville. 13523 - libc: Fix ARMv7-A/R memcpy assembly. 13524 - Fix return value if x is NaN. From Aleksandr Vyhovanec. 13525 13526 * apps/nshlib: 13527 13528 - NSH: Eliminate a warning when all memory inspection commands are disabled. 13529 13530 * apps/graphics: 13531 13532 - apps/graphics/traveler/tools: Fix linkage issue. The -lm should 13533 come after -o binname. From Alan Carvalho de Assis. 13534 13535 * apps/netutils: 13536 13537 - The CONFIG_NETUTILS_HTTPD_PATH constant is used by httpd_mmap.c and 13538 httpd_sendfile.c but It was not present in Kconfig menu. From 13539 Maciej W�jcik. 13540 13541 * apps/examples: 13542 13543 - Configurations that enable OSTEST must not disable signals. 13544 - apps/examples/ostest: Was ignoring 13545 CONFIG_EXAMPLES_OSTEST_FPUTESTDISABLE. 13546 - In apps/examples/mtdpart/mtdpart_main.c where 13547 CONFIG_EXAMPLES_MTDPART_NPARTITIONS defining is checked should be 13548 #ifndef instead of #ifdef. Noted by Oleg Evseev. 13549 13550NuttX-7.21 Release Notes 13551------------------------ 13552 13553The 121st release of NuttX, Version 7.21, was made on June 6, 2017, 13554and is available for download from the Bitbucket.org website. Note 13555that release consists of two tarballs: nuttx-7.21.tar.gz and 13556apps-7.21.tar.gz. These are available from: 13557 13558 https://bitbucket.org/nuttx/nuttx/downloads 13559 https://bitbucket.org/nuttx/apps/downloads 13560 13561Both may be needed (see the top-level nuttx/README.txt file for build 13562information). 13563 13564Additional new features and extended functionality: 13565 13566 * Core OS: 13567 13568 - pthread rwlocks: Add an implementation for read/write locks 13569 (rwlocks) into the pthread library. These locks are writer 13570 priority, such that if any writers come in they are given priority 13571 for writing. From Mark Schulte. 13572 - pthread robust mutexes: Implement robust mutex support: 13573 pthread_mutex_lock() and trylock() will return EOWNERDEAD if the 13574 mutex is locked by a thread that no longer exists. Add 13575 pthread_mutex_consistent() to recover from this situation. Keep 13576 list of all mutexes held by a thread in a list in the pthread's TCB. 13577 When pthread exits or is cancelled, mutexes held by thread are 13578 marked inconsistent and the highest priority thread waiting for the 13579 mutex is awakened. There is a configuration option to (a) support 13580 only robust mutexes, (b) support only traditional unsafe mutexes, 13581 or (c) Support both unsafe and robust mutexes via 13582 pthread_mutexattr_get/setrobust(). 13583 - pthread cancellation points: Add logic to disable cancellation 13584 points within the OS. This is useful when an internal OS function 13585 that is NOT a cancellation point calls an OS function which is a 13586 cancellation point. In that case, irrecoverable states may occur if 13587 the cancellation is within the OS. From Juha Niskanen. 13588 - clock: Add clock_resynchronize and use subseconds RTC. Add 13589 clock_resynchronize for better synchronization of CLOCK_REALTIME and 13590 CLOCK_MONOTONIC to match RTC after resume from low-power state. Add 13591 up_rtc_getdatetime_with_subseconds under 13592 CONFIG_ARCH_HAVE_RTC_SUBSECONDS to allow initializing (and 13593 resynchronizing) system clock with subseconds accuracy RTC. From 13594 Jussi Kivilinna. 13595 - clock: Add new type ssystime_t for relative 64-bit ticks, change 13596 ticks<->time conversion functions to use ssystime_t. From Jussi 13597 Kivilinna. 13598 - clock: Add testing for 32-bit overflow of 64-bit system timer. From 13599 Jussi Kivilinna. 13600 13601 * File Systems/Block and MTD Drivers 13602 13603 - drivers/mtd/w25.c: Erase sector only if it is not in erased state. 13604 From Jussi Kivilinna. 13605 13606 * Graphics/Display Drivers: 13607 13608 - drivers/lcd: Extend st7565 driver to include support for the 13609 AQM_1248A. From Masayuki Ishikawa. 13610 - drivers/lcd: Add driver for Nokia 5110 (Philips PCD8544). From Alan 13611 Carvalho de Assis. 13612 13613 * Networking/Network Drivers: 13614 13615 - Extensive modifications to support wireless network (see below). 13616 - TUN driver: Implement TAP (OSI layer 2) mode. Enable by setting the 13617 IFF_TAP flag instead of the IFF_TUN flag in ifr_flags. From Thomas 13618 Keh. 13619 - Add user-space networking stack API (usrsock). User-space 13620 networking stack API allows user-space daemon to provide TCP/IP 13621 stack implementation for NuttX network. Main use for this is to 13622 allow use and seamless integration of HW-provided TCP/IP stacks to 13623 NuttX. For example, user-space daemon can translate /dev/usrsock 13624 API requests to HW TCP/IP API requests while rest of the user-space 13625 can access standard socket API, with socket descriptors that can be 13626 used with NuttX system calls. From Jussi Kivilinna. 13627 - net/: Network driver now retains Ethernet MAC address in a union so 13628 that other link layer addresses may be used in a MULTILINK 13629 environment. 13630 13631 * Wireless Networking/Wireless Drivers: 13632 13633 - BCM43362: Support for Broadcom's BCM43362 WiFi chip was contributed 13634 by Simon Piriou as part of the port of the Particle Photon board. 13635 Only station functionality is available at present. This work 13636 includes not on the WiFi driver, but the support Particle Photon 13637 board, the infrasture for IEEE 802.11 FullMAC networking including 13638 the network device interface, WiFi configuration, AP scanning and 13639 authentication and association with an AP. 13640 - IEEE 802.11 networking tools and support. 13641 - IEEE 802.15.4 MAC support. This is an effort that was started some 13642 time back by Sebastien Lorquet (with some help from Matte Poppe). 13643 Recently, Anthony Merlino has taken on this effort and has made 13644 some significant progress. Using the Microchip MRF24J40 module with 13645 the Mikroe Clicker2-STM32 board along with a PC-based IEEE 802.15.4 13646 sniffer, Anthonly has verified correct transmittion and receipt of 13647 basic frames. 13648 - Microchip MRF24J40: As mentioned above, this IEEE 802.15.4 radio 13649 driver is now basically functional. 13650 - IEEE 802.15.4 Network Driver: A driver that interfaces the NuttX 13651 network with the IEEE 802.15.4 MAC has been developed but is still 13652 incomplete and has not been verified. 13653 - IEEE 802.15.4 Network Loopback Driver: A simple IEEE 802.15.4 MAC 13654 loopback driver was developed. This driver allowed for parallel 13655 development of the IEEE 802.15.4 MAC and 6LoWPAN. 13656 - 6LoWPAN: The Contiki 6LoWPAN stack has been ported so that works 13657 within the NuttX networking framework and interfaces with the new 13658 IEEE 802.15.4 MAC via the network driver. Live testing with 13659 IEEE 802.15.4 radios has not yet been done; all testing has used 13660 the loopback driver. There are no known problems and the stack 13661 is ready for additional testing. 13662 - Add option to enable wireless debug output. 13663 13664 * Other Common Device Drivers: 13665 13666 - Add entropy pool and strong random number generator. Entropy pool 13667 gathers environmental noise from device drivers, user-space, etc., 13668 and returns good random numbers, suitable for cryptographic use. 13669 Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm 13670 for CSPRNG output. Patch also adds /dev/urandom support for using 13671 entropy pool RNG and new 'getrandom' system call for getting 13672 randomness without file-descriptor usage (thus avoiding file- 13673 descriptor exhaustion attacks). The 'getrandom' interface is similar 13674 as 'getentropy' and 'getrandom' available on OpenBSD and Linux 13675 respectively. From Jussi Kivilinna. 13676 - XBox One controller: Adds USB host driver support for the XBox One 13677 controller. Currently only the latest version (XBox One X) 13678 controller works. The older XBox One controllers do not enumerate 13679 correctly. From Brian Webb. 13680 - drivers/analog: Add basic COMP driver. From Mateusz Szafoni. 13681 - drivers/analog: Add driver for the LTC1767L ADC. From Martin 13682 Lederhilger. 13683 - drivers/analog: Add basic OPAMP driver. From Mateusz Szafoni. 13684 - drivers/sensors: Add driver for ST HTS221 humidity sensor. From 13685 Juha Niskanen. 13686 - drivers/sensors: Add driver for ST LPS25H pressure sensor. From 13687 Juha Niskanen. 13688 - drivers/sensors: Add driver for ST LIS2DH accelerometer. From Timo 13689 Voutilainen. 13690 - drivers/usbmisc: Add driver for Fairchild FUSB301 USB type-C 13691 controller. From Harri Luhtala. 13692 - RTC: Add interface for check if RTC time has been set. New 13693 interface allows checking if RTC time has been set. This allows to 13694 application to detect if RTC has valid time (after reset) or should 13695 application attempt to get real time by other means (for example, by 13696 launching ntpclient or GPS). From Jussi Kivilinna. 13697 - Buttons: Change return value of board_buttons() and the type of 13698 btn_buttonset_t to uint32_t so that more than 8 buttons can be 13699 supported. 13700 - drivers/syslog: Use monotonic clock for timestamp when available. 13701 From Jussi Kivilinna. 13702 - SPI: Add an instance argument to the SPIDEV definitions. Thus, 13703 instead of specifying a FLASH device, for example, as SPI_FLASH, you 13704 would now use SPI_FLASH(0) where the "instance" argument now 13705 distinguishes multiple FLASH devices on the same SPI bus. From 13706 Sebastien Lorquet. 13707 - IOBs: Move from net/iob to a better location in mm/iob where they 13708 can be shared outside of the networking logic. Current also used 13709 by IEEE 802.15.4 MAC and by syslog (when buffering enabled). 13710 - syslog: Add option to buffer SYSLOG output to avoid interleaving. 13711 Uses new shareable IOBs. Additional logic to assure that the the 13712 write from the buffer is a single atomic write in normal debug 13713 output. 13714 - drivers/can: Move CAN subsystem to its own directory and put device 13715 drivers there. From Alan Carvalho de Assis. 13716 - drivers/can: Add Microchip MCP2515 CAN Bus controller driver. From 13717 Alan Carvalho de Assis. 13718 - drivers/audio: Add cs43l22 audio driver. From Taras Drozdovsky. 13719 - drivers/input: Add Cypress MBR3108 CapSense touch button driver. 13720 From Juha Niskanen. 13721 13722 * Simulation 13723 13724 - configs/sim/sixlowpan: Configuration for testing the 6LoWPAN with 13725 the IEEE 802.15.4 loopback network driver. 13726 13727 * Infineon XMC4xxx: 13728 13729 - arch/arm/src/xmc4: Initial, partial support for Infineon XMC4xxx. 13730 13731 * Infineon XMC4xxx Boards: 13732 13733 - XMC4500 Relax: Add basic board support infrastructure of Infineon 13734 XMC4500 Relax Lite v1.

Not tested for any product 13833 family, but now it at least compiles. L496 devices can have one bit 13834 wider Volatile Data Segment. From Juha Niskanen. 13835 - STM32 TIM: Add method to get timer width. Freerun timer: Use timer 13836 width to get the correct clock rollover point. 13837 - STM32 L4: Add internal flash write support. From Juha Niskanen. 13838 - STM32 L4: Port stm32l4_serial_get_uart function from STM32F7. From 13839 Juha Niskanen. 13840 - STM32 Ethernet: Add support for KSZ8081 PHY interrupts. From 13841 Sebastien Lorquet. 13842 - STM32 F4: Add I2S driver. From Taras Drozdovsky. 13843 - STM32 L4: Add IWDG peripheral. This is the same as for STM32 13844 except that prescale and reload can be changed after watchdog has 13845 been started, as this seems to work on L4. From Juha Niskanen. 13846 - STM32 F7: Add SPI DMA support. From Jussi Kivilinna. 13847 13848 * STMicro STM32 Boards: 13849 13850 - Support for the Particle Photon board was contributed by Simon 13851 Piriou. The Photon board is based on a STM32F205G MCU with and on- 13852 board BCM43362 WiFi chip that interfaces via the STM32's SDIO 13853 interface. Board configuration support includes, in addition, 13854 buttons, LEDS, IWDG, USB OTG HS, and procfs support. Configurations 13855 available for nsh, usbnsh, and wlan configurations. 13856 - Clicker2-STM32: Support for the Mikroelektronika Clicker 2 for 13857 STM32 was added by Anthony Merlino. This board, along with the 13858 MRF24J40 Click board is the platform used to deveop the IEEE 13859 802.15.4 support.

From Alan Carvalho de Assis. 13877 13878 * C Library/Header Files: 13879 13880 - C library: Add strerror_r(). 13881 - C Library: Add wcstoull(), swprintf(), wcstod(), wcstof(), wcstol(), 13882 wcstold(), wcstoul(), wcstoll() functions. Add mbsnrtowcs() and 13883 wcsnrtombs() (just returning success). Add mbtowc() and wctomb() to 13884 C++ std namespace. From Alan Carvalho de Assis. 13885 - C Library: Add ffsl(), ffsll(), fls(), flsl(), flsll() and use 13886 GCC's __builtin_ctz/__builtin_clz for faster implementation of these. 13887 From Jussi Kivilinna. 13888 - fixedmath: Add square root and b32_t conversion operators. From 13889 Jussi Kivilinna. 13890 - locale.h: Add a bogus definition of locale_t. 13891 - C library: Versions mbrlen and mbsrtowcs taken and adapted from 13892 FreeBSD code (at https://github.com/freebsd/freebsd/). From Matias 13893 v01d. 13894 13895 * Build/Configuration System: 13896 13897 - Include C++ library in 'make export'. From Alan Carvalho de Assis. 13898 - configs: Remove all setenv.sh and setenv.bat files. Remove all 13899 references to setenv.sh and setenv.bat from all config README files. 13900 - Kconfig/deconfigs: Add CONFIG_ARCH_TOOLCHAIN_GNU to indicate that 13901 the toolchain is based on GNU gcc/as/ld. This is in addition to the 13902 CPU-specific versions of the same definition. 13903 - Move prototype for up_cxxinitialize() from nuttx/include/nuttx/arch.h 13904 to apps/include/platform/cxxinitialize.h. 13905 13906 * Tools: 13907 13908 - Add initialconfig.c so that perhaps in the future we will be able to 13909 use this to generate a new configuration from scratch (rather than 13910 having to derive new configurations from existing configurations). 13911 NOTE: Not yet intregated into the build system. 13912 13913 * NSH: apps/nshlib: 13914 13915 - Added support for set [{+|-}{e|x|xe|ex}] [<name> <value>]. Set the 13916 'exit on error control' and/or 'print a trace' of commands when 13917 parsing scripts in NSH. The settinngs are in effect from the point 13918 of exection, until they are changed again, or in the case of the init 13919 script, the settings are returned to the default settings when it 13920 exits. Included child scripts will run with the parents settings and 13921 changes made in the child script will effect the parent on return. 13922 Use 'set -e' to enable and 'set +e' to disable (ignore) the exit 13923 condition on commands. The default is -e. Errors cause script to 13924 exit. Use 'set -x' to enable and 'set +x' to disable (silence) 13925 printing a trace of the script commands as they are ececuted. The 13926 default is +x. No printing of a trace of script commands as they are 13927 executed. From David Sidrane. 13928 - Print expanded variables if -x.

Only the most critical bugfixes are listed here (see the 14007ChangeLog for the complete list of bugfixes and for additional, more 14008detailed bugfix information): 14009 14010 * Core OS: 14011 14012 - Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is 14013 only a single, hard-allocated holder structure. This is problem 14014 because in sem_wait() the holder is released, but needs to remain in 14015 the holder container until sem_restorebaseprio() is called. The call 14016 to sem_restorebaseprio() must be one of the last things the 14017 sem_wait() does because it can cause the task to be suspended. If in 14018 sem_wait(), a new task gets the semaphore count then it will fail to 14019 allocate the holder and will not participate in priority 14020 inheritance. This fix is to add two hard-allocated holders in the 14021 sem_t structure: One of the old holder and one for the new holder. 14022 - Priority inheritance: sem_holder sem_findholder missing 14023 inintalization of pholder. sem_findholder would fail and code 14024 optimization covered this up. From David Sidrane. 14025 - Partial Fix priority inheritance CONFIG_SEM_PREALLOCHOLDERS=0. From 14026 David Sidrane. 14027 - Priority inheritance: sem_boostholderprio prevent overrun of 14028 pend_reprios. The second case rtcb->sched_priority <= 14029 htcb->sched_priority did not check if there is sufficient space in 14030 the pend_reprios array. From David Sidrane. 14031 - lp_worker: Guard from pend_reprios overflow. From David Sidrane. 14032 - Priority inheritance: Fixes improper restoration of base_priority in 14033 the case of CONFIG_SEM_PREALLOCHOLDERS=0. The call to 14034 sem_restorebaseprio_task context switches in the 14035 sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to 14036 releasing the holder. So the running task is left as a holder as is 14037 the started task. Leaving both slots filled thus failing to perform 14038 the boost/or restoration on the correct tcb. This PR fixes this by 14039 releasing the running task slot prior to reprioritization that can 14040 lead to the context switch. To faclitate this, the interface to 14041 sem_restorebaseprio needed to take the tcb from the holder prior to 14042 the holder being freed. In the failure case where sched_verifytcb 14043 fails it added the overhead of looking up the holder. There is also 14044 the additional thunking on the foreach to get from holer to 14045 holder->tcb. An alternate approach could be to leve the interface 14046 the same and allocate a holder on the stack of sem_restoreholderprioB 14047 copy the sem's holder to it, free it as is done in this pr and 14048 then pass that address sem_restoreholderprio as the holder. It could 14049 then get the holder's tcb but we would keep the same sem_findholder 14050 in sched_verifytcb.

From Masayuki Ishikawa. 14065 - binfmt/elf: Fix offset value when calling elf_read() in 14066 elf_sectname(). From Masayuki Ishikawa. 14067 - There can be a failure in IOB allocation to some asynchronous 14068 behavior caused by the use of sem_post(). Consider this scenario: 14069 (1) Task A holds an IOB.� There are no further IOBs.� The value of 14070 semcount is zero. Task B calls iob_alloc().� Since there are not 14071 IOBs, it calls sem_wait().� The value of semcount is now -1. (2) 14072 Task A frees the IOB.� iob_free() adds the IOB to the free list and 14073 calls sem_post() this makes Task B ready to run and sets semcount to 14074 zero NOT 1.� There is one IOB in the free list and semcount is zero. 14075 When Task B wakes up it would increment the sem_count back to the 14076 correct value. (3) But an interrupt or another task runs occurs 14077 before Task B executes.� The interrupt or other tak takes the IOB off 14078 of the free list and decrements the semcount.� But since semcount is 14079 then < 0, this causes the assertion because that is an invalid state 14080 in the interrupt handler. So I think that the root cause is that 14081 there the asynchrony between incrementing the semcount. This change 14082 separates the list of IOBs: Currently there is only a free list of 14083 IOBs. The problem, I believe, is because of asynchronies due 14084 sem_post() post cause the semcount and the list content to become out 14085 of sync. This change adds a new 'committed' list: When there is a 14086 task waiting for an IOB, it will go into the committed list rather 14087 than the free list before the semaphore is posted. On the waiting 14088 side, when awakened from the semaphore wait, it will expect to find 14089 its IOB in the committed list, rather than free list. In this way, 14090 the content of the free list and the value of the semaphore count 14091 always remain in sync. 14092 - binfmt: Fix .dtor memory allocation.

According the Datasheet 14241 the WDD Value is the lower bound of a so called Forbidden Window and 14242 to disable this we have to set the WDD Value greater than or equal to 14243 the WDV Value. This seems to be a bug in the datasheet. It looks 14244 like we have to set it to a greater value than the WDV to really 14245 disable this Thing. When triggering the Watchdog faster than the 14246 (very slow) clock source of the Watchdog fires, this Forbidden Window 14247 Feature resets the System if WDD equals to WDV.

Sugested by webbbn@gmail.com. 14303 - Save elapsed time before handling I2C in stm32_i2c_sem_waitstop(). 14304 This change follows the same logic as in previous fix to 14305 stm32_i2c_sem_waitdone(). It is possible that a context switch 14306 occurs after I2C registers are read but before elapsed time is saved 14307 in stm32_i2c_sem_waitstop(). It is then possible that the registers 14308 were read only once with "elapsed time" equal 0. When scheduler 14309 resumes this thread it is quite possible that now "elapsed time" will 14310 be well above timeout threshold. In that case the function returns 14311 and reports a timeout, even though the registers were not read 14312 "recently". Fix this by inverting the order of operations in the loop 14313 - save elapsed time before reading registers. This way a context 14314 switch anywhere in the loop will not cause an erroneous "timeout" 14315 error.

So, e.g., removing stm32_i2c_sendstop (#1744) and adding 14345 stm32_i2c_sendstart after data reading helps to make DS3231 working. 14346 From Alexander Oryshchenko; verified by David Sidrane. 14347 - STM32 F7 Serial: Serial fix for dropped data: (1) Revert the 14348 inherited dma bug from the stm32. see 14349 https://bitbucket.org/nuttx/nuttx/commits/df9ae3c13fc2fff2c21ebdb098c520b11f43280d 14350 for details. And (2) Most all CR1-CR3 settings can not be configured 14351 while UE is true. Threfore we make all operation atomic and disable 14352 UE and restore it's originalstate on exit. From David Sidrane. 14353 - STM32 L1: Fix IWDG and WWDG debug mode stop for STM32L15XX. From 14354 Juha Niskanen. 14355 - STM32 F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi 14356 Kivilinna. 14357 - STM32 F7: Add warning for RXDMA + IFLOWCONTROL combination. 14358 Combination of RXDMA + IFLOWCONTROL does not work as one might 14359 expect. Since RXDMA uses circular DMA-buffer, DMA will always keep 14360 reading new data from USART peripheral even if DMA buffer underruns. 14361 Thus this combination only does following: RTS is asserted on USART 14362 setup and deasserted on shutdown and does not perform actual RTS 14363 flow-control. Data loss can be demonstrated by doing long up_mdelay 14364 inside IRQ critical section and feeding data to RXDMA+IFLOWCONTROL 14365 UART. From Jussi Kivilinna. 14366 - STM32 F7 Serial: Do not stop processing input in SW flow-control 14367 mode. From Jussi Kivilinna. 14368 - STM32 L4 DMA: Correct bad channel definition. From Sebastien Lorquet. 14369 - STM32 F7: Warn if no DMA2 configured when using ADC with DMA. Also 14370 correct ADC channel numbers that DMA callback passes to upper half 14371 driver. From Juha Niskanen. 14372 - STM32 F7 ADC: Do not override ADCPRE_DIV when measuring 14373 internal voltage. From Juha Niskanen. 14374 - STM32 L4: Don't think these chips have DPFPU, DTCM or ITCM. From 14375 Juha Niskanen. 14376 - STM32 F7 Flash: macro naming errors, there is no FLASH_CONFIG_F for 14377 F7. From Juha Niskanen. 14378 - STM32 L4: stm32l4x6xx_pinmap: Update I2C4 and DCMI pins. From Juha 14379 Niskanen. 14380 - STM32 L4: stm32l4_i2c: change wrong macro to CONFIG_I2C_POLLED. From 14381 Juha Niskanen. 14382 - Fix STM32F7 I2C interrupt handler. From Jussi Kivilinna. 14383 - STM32: Serial Allow configuring Rx DMA buffer size. From David 14384 Sidrane. 14385 - STM32 CAN: I had the problem that the transmit FIFO size (= actual 14386 elements in FIFO) was slowly increasing over time, and was full after 14387 a few hours. The reason was that the code hit the line 14388 "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so 14389 can_xmit thinks it has sent the packet to the hardware, but actually 14390 has not. Therefore the transmit interrupt never happens which would 14391 call can_txdone, and so the size of the FIFO size does not decrease. 14392 The reason why the code actually hit the mentioned line above, is 14393 because stm32can_txready uses a different (incomplete) condition than 14394 stm32can_send to determine if the mailbox can be used for sending, 14395 and thus can_xmit forwards the packet to stm32can_send. 14396 stm32can_txready considered mailboxes OK for sending if the mailbox 14397 was empty, but did not consider that mailboxes may not yet be used if 14398 the request completed bit is set - stm32can_txinterrupt has to 14399 process these mailboxes first. Note that I have also modified 14400 stm32can_txinterrupt - I removed the if condition, because the CAN 14401 controller retries to send the packet until it succeeds. Also if the 14402 condition would not evaluate to true, can_txdone would not be called 14403 and the FIFO size would not decrease also. From Lederhilger Martin. 14404 - STM32 Serial: Fix freezing serial port. Serial interrupt 14405 enable/disable functions do not disable interrupts and can freeze 14406 device when serial interrupt is received while execution is at those 14407 functions. Trivially triggered with two or more threads write to 14408 regular syslog stream and to emergency stream. In this case, freeze 14409 happens because of mismatch of priv->ie (TXEIE == 0) and actually 14410 enabled interrupts in USART registers (TXEIE == 1), which leads to 14411 unhandled TXE interrupt and causes interrupt storm for USART. From 14412 Jussi Kivilinna. 14413 - STM32 I2C: Make private symbols static. From Juha Niskanen. 14414 - STM32 L4 GPIO: Put back EXTI line source selection. From Juha 14415 Niskanen. 14416 - STM32 L4 RTC: Store RTC MAGIC to backup reg, not to address zero. 14417 From Juha Niskanen. 14418 14419 * STMicro STM32 Boards: 14420 14421 - Disable serial console on stm32f103-minimum usbnsh example project 14422 config. Devices enumerate after this change. From Bob Ryan. 14423 - Nucleo-144: Default for choice in Kconfig was not one of the 14424 possible choices. 14425 - Nucleo-F4X1RE User LEDS: Issue #51 reports compilation problems with 14426 stm32_userled.c. Reported by Gappi92. 14427 14428 * TI Tiva Drivers: 14429 14430 - Tiva I2C: Correct an error in conditional compilation. 14431 - Tiva SSI: Resolves issue 52 'Copy-Paste error in 14432 tiva_ssibus_initialize()' submitted by Aleksandr Kazantsev. 14433 14434 * C Library/Header Files: 14435 14436 - C Library vsnprintf(): Fix precision for string formatting. Fixes 14437 use of format precision to truncate input string. From Jussi 14438 Kivilinna. 14439 - C Library vsnprintf(): If size is zero, then vsnprintf() should 14440 return the size of the required buffer without writing anything. 14441 From Jussi Kivilinna. 14442 - C Library netdb: in dns_query_callback, ret != -EADDRNOTAVAIL 14443 condition consumes error returns including EAGAIN in this case, 14444 dns query retransmission doesn't work. From Ritajina. 14445 - C Library netdb: Fix time info in lib_dnscache.c. From Masayuki 14446 Ishikawa. 14447 - C Library netdb: Fix bugs in lib_gethostbynamer.c. This fix sets 14448 h_name in struct hostent returned by gethostbyname(). From Masayuki 14449 Ishikawa. 14450 - C Library Defect Workaround: replace '%6.6u' format with an 14451 equivalent '%06u'. From Tomasz Wozniak. 14452 14453 * Tools 14454 14455 - Fix mksyscall host binary name. From Alan Carvalho de Assis. 14456 14457 * Applications (apps/) 14458 14459 - Fix some calls to task_create(): argv[0] is the first parameter, not 14460 the name of the task. 14461 - Bitbucket Issue 5: I found an unexpected behavior in apps/ 14462 configuration generation. Adding external symbolic link in apps/ 14463 directory and using Make.defs for Kconfig generation, Kconfig file 14464 has a wrong path in the source argument. It contains original dir 14465 path outside of the source tree instead path to sub-directory in 14466 apps/. The problem is connected with make/system symbolic link path 14467 resolution. Corrected by a patch submitted by Artur Madrzak with 14468 Issue 5. 14469 - apps/: Make more globals static to avoid name clashes. From Juha 14470 Niskanen. 14471 14472 * NSH: apps/nshlib: 14473 14474 - NSH library: In nsh_argexand(), if CONFIG_NSH_ARGCAT is defined but 14475 CONFIG_NSH_CMDPARMS defined and/or CONFIG_DISABLE_ENVIRON not 14476 defined, then there is a situation that causes an infinite loop in 14477 the parser. Noted by Freddie Chopin. 14478 - NSH library: Fix building when CONFIG_NET_USRSOCK enabled with other 14479 link-layers. From Jussi Kivilinna. 14480 - NSH library: Fix some warnings about integer/pointer casts of 14481 different sizes (probably only effects 64-bit simulation). 14482 - NSH library: Fix open flags in nsh_codeccmd.c. From Masayuki 14483 Ishikawa. 14484 - I need to look at the registers that are at or around 0xe000ef90. 14485 Using mw and xd, I see that nsh does not support pointers greater 14486 than 0x7fffffff. A quick look at the source shows that the pointers 14487 for those two commands are set with calls to strtol() rather than 14488 strtoul(). Changing the two pointer-setting instances to strtoul() 14489 fixes the problem, at least for my architecture/config. From Ian 14490 McAfee. 14491 - NSH library: Fix a resource leak in cmd_hexdump(). From Nobutaka 14492 Toyoshima. 14493 14494 * Examples/Tests: apps/examples: 14495 14496 - apps/examples/hidkbd: Remove call to arch_usbhost_initialize(). 14497 That is violation of the OS interfacing rules and will no longer be 14498 supported. USB host should be initialized as part of the normal 14499 board bring-up logic as with any other devices and should not involve 14500 illegal calls from applications into the OS. 14501 - apps/examples/usbterm: Removed because it is not very useful and 14502 because it can be configured to use an illegal call into the OS. 14503 - examples/mm: Fix Makefile. Built-in was not being registered. 14504 - examples/hidkbd: Add some missing configuration settings. 14505 - examples/random: Avoid stack overflows. From Juha Niskanen. 14506 - examples/nettest: Fix an error in pre-processor expression. 14507 - examples/mtdpart: Prevent part array overflow. mtdpart examples 14508 create partions and allocate from 1 index not a 0 index to part[] 14509 array. This cause buffer overflow for part array. This change fixes 14510 this problem. From EunBong Song. 14511 - examples/can: Fix can example app to print data when 14512 CONFIG_EXAMPLES_CAN_READ is defined. From Alan Carvalho de Assis. 14513 14514 * Network Utilities: apps/netutils: 14515 14516 - Not a clean fix, but at least makes DHCP working with 14517 CONFIG_NETDEV_MULTINIC. From Andreas Bihlmaier. 14518 - Ensure netlib will not be broken when setip will not bring the 14519 network up anymore. From Sebastien Lorquet. 14520 14521 * CAN Utilities: apps/canutils: 14522 14523 - Fix libcanard github download link to get it compiling correctly. 14524 From Alan Carvalho de Assis. 14525 - Fix to use the new canardInit() function. From Alan Carvalho de 14526 Assis. 14527 14528 * System Utilities (apps/system) 14529 14530 - system/dhcpc: Add missing argument of fprintf. 14531 14532 * Tools (apps/tools): 14533 14534 - The dedicated windows tool at tools/mkkconfig.bat uses $APPSDIR, 14535 which is not a windows shell variable, and is left uninitialized, but 14536 in fact should be the current directory. From Sebastien Lorquet. 14537 14538NuttX-7.22 Release Notes 14539------------------------ 14540 14541The 122nd release of NuttX, Version 7.22, was made on September 9, 2017, 14542and is available for download from the Bitbucket.org website. Note 14543that release consists of two tarballs: nuttx-7.22.tar.gz and 14544apps-7.22.tar.gz. These are available from: 14545 14546 https://bitbucket.org/nuttx/nuttx/downloads 14547 https://bitbucket.org/nuttx/apps/downloads 14548 14549Both may be needed (see the top-level nuttx/README.txt file for build 14550information). 14551 14552Additional new features and extended functionality: 14553 14554 * Core OS: 14555 14556 - pthreads: Move functions from sched/pthreads to libc/pthreads. These 14557 functions just coordinate other OS interface calls but are not a 14558 fundamental OS interfaces and, hence, do not belong within the OS: 14559 pthread_yield(), pthread_once(), pthread_cond_init(), 14560 pthread_cond_destroy(), pthread_barrier_init(), 14561 pthread_barrier_destroy(), and pthread_barrier_wait(). 14562 - Add power-related debug output. 14563 14564 * File Systems/Block and MTD Drivers 14565 14566 - RAMTRON: Add support for splitting block writes in chunks. Some 14567 Re-RAMs like MB85AS4MT have a write buffer size limitation. From 14568 Boris Astardzhiev. 14569 - MTD: Add driver for Macronix QuadSPI flash memory. From Simon Piriou. 14570 14571 * Graphics/Display Drivers: 14572 14573 - SSD1306 LCD Driver: (1) Separate lcd_dev_s setup to separate object. 14574 g_oleddev takes 1 KiB because framebuffer and was allocated to .data 14575 section because of lcd_dev_s function pointer setup. Move lcd_dev_s 14576 setup out, so that g_oleddev goes to .bss and avoid wasting ROM. (2) 14577 Fix memory corruption caused by ssd1306_getrun(). ssd1306_getrun was 14578 writing one extra byte (with value 0) past target buffer when pixlen 14579 is multiple of 8. When pixlen was not multiple of 8, last byte of 14580 buffer was fully cleared, instead of modifying only the (pixlen % 8) 14581 bits of last byte. (3) Add support for board power control. 14582 ThingseeOne has regulator for controlling display power on/off. Patch 14583 adds support for board based power control to SSD1306 driver. (4) Add 14584 DD-12864WO-4A/SSD1309 support to SSD1306 driver. From Jussi Kivilinna. 14585 14586 * Networking/Network Drivers: 14587 14588 - Sockets: Support listening sockets in the getsockname() function. 14589 From Roland Takacs. 14590 - IP Forwading: At the IP level, network may be configured to forward 14591 IP packets that are not destined for the target through a different 14592 network device, decrementing the packet TTL. 14593 - IP forwarding: Add optional support to forward broadcast and 14594 multicast packets. Add missing ICMP support. 14595 - ICMPv6: Add 6LoWPAN and IP forwarding support. 14596 - ICMPv6: Support source link-layer address option in RA. From 14597 Masayuki Ishikawa. 14598 - TUN Driver: Add definitions that will permit TUN-only networking. 14599 - Socket I/F: Created a socket interface used to provide socket support. 14600 Each address family has an interface that describes how to perform 14601 socket operations on that address family. Currently only a couple of 14602 methods are defined in the socket interface call table 14603 - Remove CONFIG_NET_MULTILINK. This increases code size by a little, 14604 but greatly reduces the complexity of the network code. 14605 - Network procfs: Add support for routing tables at proc/net/route. 14606 - Network procfs: Add support for network procfs statistics for the 14607 PF_IEEE802154 address family. 14608 - Network Driver Backlog: Remove driver based backlog support. This 14609 affects the entire network, but is used by only one driver. The only 14610 supported RX backlog is now via common read-ahead buffering. 14611 14612 * Wireless Networking/Wireless Drivers: 14613 14614 - IEEE 802.15.4 MAC / MRF24J60 Driver: Extensive updates for 14615 association/beacon-enabled networks. From Anthony Merlino. 14616 - IEEE 802.15.4 MAC / MRF24J60 Driver: Hook in setdevmode from newly 14617 added radio attribute setting. From Anthony Merlino. 14618 - IEEE 802.15.4 MAC: Supports get request for coordinator address. From 14619 Anthony Merlino. 14620 - IEEE 802.15.4 MAC: Notify radio layer of changes in devmode. From 14621 Anthony Merlino. 14622 - IEEE 802.15.4: Add special attribute that can be used to perform a 14623 regdump of the radio. From Anthony Merlino. 14624 - IEEE 802.15.4 loopback driver: Better simulation addressing: short 14625 and extended addresses, panid, and IP address conversion. 14626 - IEEE 802.15.4 Network Driver: Add logic to setup the network mask, 14627 update the MAC-based IPv6 addressing when the network is brought up. 14628 The idea is that addressing changes are supposed to occur only while 14629 the network is down but won't take effect until the network is up 14630 again. 14631 - PktRadio: Add an infrastructure to support networking on generic 14632 (non-IEEE 802.15.4) packet radios. 14633 - PktRadio Loopback Driver: Add a PktRadio loopback network driver to 14634 testing testing with 6LoWPAN and PktRadios on the simulator. 14635 - Spirit Network Driver: The Spirit1 radio (SPSGRF-915) is the first 14636 generic PktRadio Network driver. Based on STMicros STack packets 14637 with 8-bit addressing. We need to use the STack packets in order to 14638 provide the source address and automatic ACKing. 14639 - Network procfs: Fix so that PktRadio address are shown correctly. 14640 - Networking: Add support for some packet radio IOCTL commands. 14641 - 6LoWPAN: Added handling for TCP and ICMPv6 packets. 14642 - 6LoWPAN: Add configurable support for 6LoWPAN star topology. With 14643 this change, the endpoints which are the 'points' of the star will 14644 forward all traffic to the coordinator. The coordinator is assumed to 14645 be the 'hub' of the star. This function also used IPv6 forwarding. 14646 - 6LoWPAN: The original, Contiki-based design used only a single buffer 14647 for reassemblying larger packets. This could be a problem issue for 14648 hub configurations which really need the capability concurrently 14649 reassemble multiple incoming streams concurrently. These was also a 14650 design issue in that the reassembly buffer could be corrupted by 14651 outgoing packets. The design was extended to support multiple 14652 reassembly buffers, each associated with the reassembly tag and source 14653 address. This assures that there can be be no corruption of the 14654 reassembly once it has started. 14655 - 6LoWPAN PktRadio: Now radio agnostic. All IEEE 802.15.4 dependencies 14656 have been removed or isolated so that 6LoWPAN can be used with any 14657 kind of packet radio. This involved things like: (1) generalizing 14658 the representation of radio MAC meta-data, (2) changes to handle 14659 variable-length radio addresses, (3) removal of all explicit IEEE 14660 802.15.4 types, references, and interfaces, (4) a new radio driver 14661 interface to return 'capabilities' of the drvier. 14662 - ICMPv6: Update so that ICMPv6 can be used with 6LoWPAN. 14663 - IPv6 Neighbor: Update table format to support IEEE 802.15.4 MAC 14664 addresses. 14665 - PF_IEEE802154 Address Family: Add support for the PF_IEEE802154 14666 address family socket type. This socket is similar to the PF_PACKET, 14667 "raw" packet address family except that: (1) it supports only 14668 SOCK_DRAM, not SOCK_RAW, and (2) works only with IEEE 802.15.4 14669 MAC-based radios. This address family permits simple access to IEEE 14670 802.15.4 IOCTLs and frame-level network transfers. 14671 14672 * Other Common Device Drivers: 14673 14674 - Dynamically configurable USB composite devices: We developed a huge 14675 Changeset over a year ago to make USB Composite configuration 14676 dynamical and be able to instantiate the CDC/ACM multiple times inside 14677 this device. We use this feature to switch between one in typical USB MSC + CDC/ACM configuration and up to three CDCACMs dynamically. 14678 I've changed the interface for some USB-Functions to receive also the 14679 dynamic configuration. From Frank Benkert. 14680 - Franks' change remained on a branch until all issues were resolved. 14681 the current version in Master is complete and ready for use. 14682 - power: battery_charger: Add ioctl for charging input current.

From Juha 14699 Niskanen. 14700 - ADC Driver: Add poll support. From Juha Niskanen. 14701 - BCH Driver: Add poll support. From Jussi Kivilinna. 14702 - RTC Driver: Extend the RTC framework with an alarm read ioctl 14703 (RTC_RD_ALARM). Through it consumer could get configuration settings 14704 about previously scheduled hardware alarms (active status, hours, 14705 minutes, seconds). From Boris Astardzhiev. 14706 14707 * Simulation 14708 14709 - sim/ipforward: Add an IP forwarding configuration using TUN devices 14710 and apps/examples/tun. 14711 - Console: Add non blocking read to devconsole driver. From Simon 14712 Piriou. 14713 - Networking: Poll for TX frames to speed up driver. From Simon Piriou. 14714 - pf_ieee802154: Add configuration for testing PF_IEEE802154 address 14715 family sockets. 14716 - ARM Simulator: Adds necessary functionality to build Simulator under 14717 ARM Linux. Tested only on Raspberry3. Currently setjmp/longjmp do not 14718 save/restore floating point registers. From Nickolay Semyonov. 14719 14720 * MicroChip/Atmel SAML21 Drivers: 14721 14722 - SAML21 I2C driver. Developed for and contributed with permissin from 14723 Filament company. From Alan Carvalho de Assis. 14724 - SAMD/L21 USB Driver: Add a USB driver. Developed for Filament Inc. 14725 by Offcode, LTD. From Janne Rosberg. 14726 14727 * MicroChip/Atmel SAMv7 Boards: 14728 14729 - SAMV71-XULT: Add support for the MRF24J40 radio and create a 14730 mrf24j40-starhub configuration. 14731 - SAME70-Xplained: Add MRF24J40 support. 14732 14733 * NXP Freescale Kinetis Drivers: 14734 14735 - Kinetis USB Improvements: usbdev clean up ensuring proper use of HW. 14736 Rework suspend and resume logic so they perform properly. Made attach 14737 and detach functions optional. As they do not make sense for a bus 14738 powered device. From David Sidrane. 14739 - Kinetis SPI driver: From David Sidrane. 14740 - Kinetis: I2C driver added I2C3, reference counting and reset. 14741 Refactored the driver to support reference counting and reset added 14742 I2C3. From David Sidrane. 14743 - Kinetis RTC: Implementation of the alarm read function. 14744 14745 * NXP Freescale Kinetis Boards: 14746 14747 - configs/teensy-3.x USB: Define USBOTG-FS Read from FLASH access in 14748 board config. Allow the board config to define the USBOTG-FS to have 14749 Read access to FLASH. From David Sidrane. 14750 - configs/teensy-3.x: Removed call to khci_usbattach. The call is not 14751 need by the driver if CONFIG_USBDEV_BUSPOWERED=y. On a USB powered device if we are running we are attached. From David Sidrane. 14752 - freedom-k66f: Use SPI driver. Initalize SPI1 on connector J6. No 14753 real use, as of yet. From David Sidrane. 14754 14755 * NXP Freescale LPC43xx: 14756 14757 - LPC43xx: Modify up_allocate_(k)heap() to support PROTECTED mode. From 14758 Alan Carvalho de Assis. 14759 14760 * NXP Freescale LPC4xx Boards: 14761 14762 - configs/Bambino: Add protected mode configuration to Bambino board. 14763 From Alan Carvalho de Assis. 14764 14765 * On Semiconductor LC823450 14766 14767 - LC823450: Initial support for ON Semiconductor LC823450. From Masayuki 14768 Ishikawa. 14769 - LC823450: eMMC/SD and USB support for LC823450. From Masayuki Ishikawa. 14770 14771 * On Semiconductor LC823450 Boards 14772 14773 - LC823450-XGEVK: LC823450-XGEVK board support. From Masayuki 14774 Ishikawa. 14775 - LC823450-XGEVK: Add eMMC/SD and USB support. From Masayuki Ishikawa. 14776 14777 * STMicro STM32: 14778 14779 - STM32 L4: Add support for the STM32L475 family. 14780 - STM32 L4 RCC: Enable ADC clock source. From Juha Niskanen. 14781 - STM32: Allow clock frequencies > 168 Mhz on stm32f427/429. We need 14782 to enable the power overdrive for this case. This change allows the 14783 required bits to be set in proper sequence. It also modifies the 14784 local register access operations to allow more than 16-bit registers. 14785 From Sebastien Lorquet . 14786 - STM32 F4: Add support for STM32F433RC. From Alan Carvalho de Assis. 14787 - STM32 F7: Add new configuration option for enabling flash ART 14788 Accelerator and flash prefetcher. From Jussi Kivilinna. 14789 14790 * STMicro STM32 Drivers: 14791 14792 - STM32 TIM: Add the set counter function for stm32 timers. From 14793 Sergey Ustinov. 14794 - STM32 HRTIM: Update HRTIM definitions. Add HRTIM driver. From 14795 Mateusz Szafoni. 14796 - STM32 HRTIM: Add HRTIM character driver. From Mateusz Szafoni. 14797 - STM32 HRTIM: Fix DAC triggers configuration, Add missing master timer 14798 logic, enable DAC triggering. From Mateusz Szafoni. 14799 - STM32 HRTIM: Add DMA configuration. From Mateusz Szafoni. 14800 - STM32 HRTIM: Add burst mode configuration. From Mateusz Szafoni. 14801 - STM32 RTC: Port Boris Astardzhiev's RTC change for STM32L4 to STM32. 14802 - STM32 DAC: Add support for HRTIM triggering. Separate dma buffer 14803 configuration for channels. From Mateusz Szafoni. 14804 - STM32 DAC: Conditional logic for timer triggering, fix TSEL 14805 configuration when HRTIM, DMA request remapping, Add DMA buffers 14806 initialization logic. From Mateusz Szafoni. 14807 - STM32 DAC: Support external triggering for DMA transfer. From Mateusz 14808 Szafoni. 14809 - STM32 L1 TIM: Add base address for TIM11. From Juha Niskanen. 14810 - STM32 F4 FLASH: Enable/disable the flash write protection on any 14811 sector. I have verified it to work on the STM32 F427. From Sebastien 14812 Lorquet. 14813 - STM32 F4 Clocking: To use an external oscillator module (not just a 14814 crystal) with the STM32F4, one needs to enable the HSEBYP bit in the 14815 RCC_CR register. This change allows an integrator to define 14816 STM32_RCC_CR_HSEBYP in their board.h file if they want this 14817 configuration. From Jeff. 14818 - STM32 F4 USB: I'm working on bringing up USB full-speed support on 14819 STM32F405.� My board does not include a USB power switch, VBus 14820 sensing, over current detection, or ID pin. This commit add a 14821 config�STM32_OTGFS_VBUS_ CONTROL which lets us selectively disable 14822 VBus sensing and control.� I also sneaked in a change to disable the 14823 configgpio call for the ID pin, which is only used in OTG mode which 14824 isn't supported yet.� The only pins that need to be initialized should 14825 be OTGFS_DP and OTGFS_DM. From Jeff. 14826 - STM32 FLASH: Add CONFIG_STM32_STM32F469 support. From David Sidrane. 14827 - STM32 COMP: Add default INM configuration and some missing COMP 14828 1,3,5,7 code. From Mateusz Szafoni. 14829 - STM32 F33: Add missing SYSCFG CFGR3 definitions. From Mateusz Szafoni. 14830 - STM32 L4 Serial: Allow configuring Rx DMA buffer size. From Juha 14831 Niskanen. 14832 - STM32 L4 COMP: Input minus pin extended selection. From Juha Niskanen. 14833 - STM32 L4 COMP: Bind to upper half comp driver. From Pekka Ervasti. 14834 - STM32 L4 DAC: Port from STM32. Add ADC register definitions. From 14835 Juha Niskanen. 14836 - STM32 L4 DAC: Add option for routing DAC output to ADC. Actually 14837 write something to the DAC DMA buffer. From Juha Niskanen. 14838 - STM32 L4 DAC: Separate DMA buffer configuration for channels. From 14839 Juha Niskanen. 14840 - STM32 L4 ADC: Implement peripheral. From Juha Niskanen. 14841 - STM32 F7: Definitions for I2C4, SDMMC2. Adapted RAM start / size to 14842 internal SRAM. From Titus von Boxberg. 14843 - STM32 F7 I2C4: I2C4_SDA can also be on GPIO PB7. From Titus von 14844 Boxberg. 14845 - STM32 F7 LTDC: Option for DSI output, inconsistency: the stm32f746 14846 does not feature a DSI interface. compilable with LTDC_INTERFACE and 14847 LTDC_USE_DSI. From Titus von Boxberg. 14848 - STM32 F7 Clocking: Added functions for DSI clock source selection. 14849 From Titus von Boxberg. 14850 - STM32 F7 Clocking: Enable APB2 DSI clock. From Titus von Boxberg. 14851 - STM32 F7 LTDC: No board specific dithering values used; corrected 14852 dithering init. Corrected LIPOS/LIPCR calculation. Change only 14853 polarity bits in LTDC_GCR. From Titus von Boxberg. 14854 - STM32 F7 Reset: Added function for reset. From Titus von Boxberg. 14855 - STM32 F7 DMA: DMA add dcache alignment check in stm32_dmacapable. In 14856 the case dcache write-buffed mode is used (not write-through) buffer 14857 alignment is required for DMA transfers because a) 14858 arch_invalidate_dcache could lose buffered writes data and b) 14859 arch_flush_dcache could corrupt adjacent memory if the maddr and the 14860 mend+1, the next next address are not on ARMV7M_DCACHE_LINESIZE 14861 boundaries. From David Sidrane. 14862 - STM32 F7 SDMMC: SDMMC remove widebus limitation on DMA. There is no 14863 documantation for the STM32F7 that limits DMA on 1 bit vrs 4 bit 14864 mode. From David Sidrane. 14865 - STM32 F7 SDMMC: SDMMC add dcache alignment check in 14866 dma{recv|send}setup. In the case where CONFIG_SDIO_PREFLIGHT is not 14867 used. 14868 - STM32 F7 RTC: Port Boris Astardzhiev's RTC change for STM32L4 to 14869 STM32F7. 14870 14871 * STMicro STM32 Boards: 14872 14873 - STM32F103-Minimum: Add GPIO device driver example. From Alan 14874 Carvalho de Assis. 14875 - STM32F103-Minimum: Add small hello example for STM32F103-Minimum 14876 board. From Alan Carvalho de Assis. 14877 - STM32F103-Minimum: Add support for SmartFS on Winbond W25 SPI NOR 14878 Flash. From Alan Carvalho de Assis. 14879 - STM32F103-Minimum: (1) Enable CONFIG_MTD_PARTITION in Kconfig if flash 14880 partition is enabled and (2) Update the README.txt file with info 14881 needed to get SmartFS working. From Alan Carvalho de Assis. 14882 - Nucleo-F334R8: Add HRTIM initialization. From Mateusz Szafoni. 14883 - Nucleo-F334R8: UART2 is default serial port (STLINK Virtual Port). 14884 From Mateusz Szafoni. 14885 - Clicker2-STM32: Add a configuration that was used with the MRF24J60 14886 for 6loWPAN testing. 14887 - Clicker2-STM32: Allow both IEEE 802.15.4 MAC character and network 14888 devices to be registered. 14889 - Clicker2-STM32: Add configurations to support the endpoint and hub 14890 roles in a star topology. 14891 - Clicker2-STM32: Add support for per-function-call stack checking. 14892 From Anthony Merlino. 14893 - Clicker2-STM32: Configure EDBG SPI CS just to make that it is 14894 disabled. 14895 - STM32F4 Discovery: Add logic to register the button driver and the 14896 user led driver if so configured. From Jan Pobrislo. 14897 - STM32F4-Discovery: Add a configuration for testing libc++. From Alan 14898 Carvalho de Assis. 14899 - B-L475E-IOT01A: Add support for the STMicro B-L475E-IOT01A board. 14900 From Simon Piriou. 14901 - B-L475E-IOT01A: Add support for the SPSRGF/Spirit1 radio module. Add 14902 a configuration for testing sprit radio. 14903 - B-L475E-IOT01A: Add configurations to support a star topology. 14904 - B-L475E-IOT01A: Add basic support for external Macronix QuadSPI flash 14905 memory. From Simon Piriou. 14906 - B-L475E-IOT01A: Enable UDP broadcast test in the spirit-starhub 14907 configuration. 14908 - STM32F334-DISCO: Add STM32F334-DISCO basic support. From Mateusz 14909 Szafoni. 14910 - STM32F746-Disco: Add ADC3 support. From Ivan Ucherdzhiev. 14911 - STM32L476-Disco: Add a knsh configuration that may be used to test 14912 the PROTECTED build mode. 14913 - STM32F769I-DISCO: Initial port to STM32F769I-DISCO. From Titus von 14914 Boxberg. 14915 14916 * C Library/Header Files: 14917 14918 - Move TUN ioctl command to include/nuttx/net/ioctl.h so that it will 14919 always be unique. 14920 - Math Library: Port gamma() and lgamma() from FreeBSD to NuttX. From 14921 Alan Carvalho de Assis. 14922 - C++: Compilation with recent C++ compiler needs an overloaded delete 14923 operator that includes a size_t size argument. New sized delete 14924 operators are only for C++14 and above. 14925 14926 * Build/Configuration System: 14927 14928 - Initial clang compile. From Goran Mekic. 14929 - Add CLANG definitions in Kconfig and Toolchain.defs. 14930 - drivers/wireless/ieee802154: Moved radios to individual 14931 sub-directories. From Anthony Merlino. 14932 - Makefile.unix: Add savedefconfig target. From Gwenhael Goavec-Merou. 14933 - Add Gwenhael's change to Makefile.win and update README.txt to 14934 described the new make target. 14935 - All defconfig files are now in the compressed format created with 14936 'make savedefconfig.' The original .config file can be reconstituted 14937 using 'make olddefconfig.' 14938 - Build System: It is no longer necessary to have a unique Make.defs 14939 file for each configuration. A board may share a common Make.defs 14940 file in the scripts directory. Duplicate Make.defs files removed; 14941 common Make.defs file moved to the scripts/ sub-directory for each 14942 board. 14943 - Networking: Move INET socket interface out of net/sockets to its own 14944 directory net/inet. 14945 14946 * Tools: 14947 14948 - testbuild.sh: Added -x to fail build on errors for continous 14949 integration (CI). On CI we want to know ASAP of a failure. From 14950 David Sidrane. 14951 - Improve configure.sh behavior: (1) enable to call from top directory. 14952 (2) enable to designate direct path for config. (3) install .gdbinit 14953 if the target has. From Hidetaka Takano. 14954 - Update tools/configure.c to same functionality as configure.sh. Add 14955 an array of optional file names. Currently, .gdbinit is the only 14956 optional file but other things like IDE-specific project files might 14957 need to be copied as well. 14958 - tools/configure.sh will now copy Eclipse project files if they are 14959 present in the board directory file. 14960 - Update configure.sh, configure.bat, configure.c: With compressed 14961 format, part of the installation requires that we run 'make 14962 olddefconfig' to restore the uncompressed defconfig format. Also, 14963 while I was at it, I also added options to select host platform on 14964 configure command line. 14965 - tools/refresh.sh: Now runs make savedefconfig before copying the new 14966 defconfig file in place; Also, added a new option --defaults. Since 14967 the number of defaults that you now have to answer is so large, the 14968 option lets you just accept the default values. So it works just like 14969 --silent but still prompts you for the decision to save or discard the 14970 new defconfig file. 14971 - tools/refresh.sh: Update so that it can find the Make.defs file in 14972 the new location. 14973 14974 * NSH: apps/nshlib: 14975 14976 - NSH Library: Add a Telnetd command. This is needed when network 14977 initialization is deferred. In that case, telnet daemon cannot be 14978 started until the network is finally initialized. The telnetd command 14979 was added just for that case: So that the telnet daemon can be 14980 started from the NSH command line after the network is configured. 14981 - NSH Library: Misc changes needed for PktRadio support. 14982 - NSH Library: Extend ifconfig command so that it can set variable 14983 length packet radio addresss. 14984 - NSH Library: Update addroute and delroute command. The would support either 14985 IPv4 or IPv6, but not both. Allow expression of the netmask in IPv4 CIDR or 14986 IPv6 slash notation. This really reduces the pain of using the commands, 14987 especially for IPv6. 14988 - NSH Library: Add a route command that will dump the content of routing table. 14989 14990 * Examples/Tests: apps/examples: 14991 14992 - examples/udp: Add configurable network device name; Add option to 14993 suppress network initialization which is not needed if started by NSH 14994 or for 6LoWPAN. 14995 - examples/udp: Fix registration as a built-in program; Change some 14996 naming to make room for a second target. Current one endpoint is the 14997 target and one is the host. This will (eventually) allow two targets 14998 to be both endpoints of the test. Change build so that both server 14999 and client can be on a target, rather than one on the target one on 15000 the host PC. Server IP address may not be provided on the command line. 15001 - examples/udp: Port numbers need to be configurable to work with 15002 6LoWPAN. Need to bind the client socket to a port number. This was 15003 not required before so is a apparently a change in the UDP packet 15004 dispatch logic. 15005 - examples/udp: Enable testing with the broadcast address. 15006 - examples/nettest: Support target boards on both ends of the test. 15007 Separate out network initialization so that it may be used by both a 15008 target server and a target client. Fix client/server naming 15009 confusion; Add command line option to select the server address on the 15010 target. Add support for both enpoints on target boards vs. one on a 15011 target and one on the host PC. 15012 - examples/nettest: The send buffer size is now a configuration option. 15013 - examples/nettest: Loopback option should be available in Kconfig for 15014 PktRadio. 15015 - examples/keypadtest: REMOVED and warehoused in the Obsoleted 15016 repository. This was just a bad clone of apps/examples/hidkbd for a 15017 keypad driver that was removed years ago. It also uses illegal 15018 function calls into the OS. So it has no purpse: It is redundant, it 15019 uses illegal interfaces, and is a test for non-existent code. 15020 - examples/ipforward: Add an IP forwarding example using only TUN 15021 devices. Test extended to test forwarding of ICMPv6 multicast messages. 15022 - Implement powermonitor example for ltc4151 current and voltage 15023 monitor. From Giorgio Gro�. 15024 - examples/pf_ieee802154: Add for testing PF_IEEE802154 sockets. Add 15025 PANID to command line options; Cannot bind to address zero... There is 15026 no counterpart to INADDR_ANY for these radios (not now at least). 15027 - examples/dac: Add DAC example. From Juha Niskanen. 15028 15029 * Network Utilities: apps/netutils: 15030 15031 - netutils/telnetc: This a port of libtelnet to NuttX. 15032 - netutils/telnetd and users of telnetd: Add support for IPv6. 15033 - netutils/thttpd: Remove the netstats demo. This depends on an 15034 illegal function call and cannot be supported. That example could be 15035 replaced with logic that uses the procfs network entries as was done 15036 for NSH which had the same issue. But I am too lazy to implement that. 15037 - netutils/netlib: Add support for PktRadio IOCTL commands. 15038 - netutils/netlib: Add a helper to decode short addresses. 15039 15040 * Wireless Utilities: apps/wireless: 15041 15042 - wireless/ieee802154/i8sak: Rewrote i8sak to be test CLI for IEEE 15043 802.15.4 MAC layer. From Anthony Merlino. 15044 - wireless/ieee802154/i8sak: Updates to i8sak for 15045 association/beacon-enabled changes to IEEE 802.15.4. From Anthony 15046 Merlino. 15047 - wireless/ieee802154/i8sak: Add option to make it easy to send large 15048 frame for testing purposes. From Anthony Merlino. 15049 - wireless/ieee802154/i8sak: Add scan command. From Anthony Merlino. 15050 - wireless/ieee802154/i8sak: Add coordinfo command allowing you to 15051 poll various attributes related to the coordinator. From Anthony 15052 Merlino. 15053 - wireless/ieee802154/i8sak: Add a option to retry on failures to the 15054 assoc command (usually meaning tht the coordinator is not yet up). 15055 - iwireless/ieee802154/8sak: Add reset command to reset the MAC layer. 15056 Adds option to assoc command -t to specify how long to wait for a 15057 response from the Coordinator. From Anthony Merlino. 15058 - ieee802154/i8sak: Adds command to trigger regdump of radio. From 15059 Anthony Merlino. 15060 15061 * System Utilities (apps/system) 15062 15063 - apps/system/composite: Update to apps/system/composite assocated with 15064 big changes to the composite device logic. From Frank Benkert. 15065 - apps/system/composite: Remove CDC/ACM and MSC configuration logic. 15066 This belongs in the OS composite initialization. Add and argument so 15067 that you can select the USB composite configuration to be attached. 15068 Restore USB tracing; remove unused field in a structure. Remove 15069 configuration settings that are no longer used. Fix configuration 15070 selecting.. was setting the port number, not the configure ID. Also 15071 add a configuration option to select the default configuration. 15072 - apps/system/composite: Add a configuration option to the boardctl() 15073 calls to support multiple composite device configurations dynamically. 15074 - apps/system/composite: Remove references to USBMSC. There still 15075 dependencies on CDC/ACM in the serial USB trace output. 15076 - apps/system/telnet: Add Telnet Chat deamon and client from 15077 libtelent. 15078 15079 * Platform-Specific Support (apps/platform) 15080 15081Bugfixes. Only the most critical bugfixes are listed here (see the 15082ChangeLog for the complete list of bugfixes and for additional, more 15083detailed bugfix information): 15084 15085 * Core OS: 15086 15087 - Fix ELF loader up_checkarch on ARM arch. From Cristian Condurache. 15088 - pthread_mutex_unlock(): Missing check for the case where 15089 pthread_mutex_lock() is called when the mutex is not locked. In that 15090 case, it would increment the underlying semaphore above 1. This is 15091 the fix for a problem noted by initialkjc@yahoo.com. 15092 - sig_timedwait(): Pending signal structure used after it has been 15093 releasd. From anonymous Bitbucket Issue 59. 15094 - mm_mallinfo: do heap end debug assert check with heap semaphore held. 15095 From Jussi Kivilinna. 15096 - sched/: Fix return value in sched_setaffinity(). From Masayuki 15097 Ishikawa. 15098 - Work Queues: work_queue() must cancel existing work prior to queuing 15099 new work, otherwise the work queue list structure can become 15100 corrupted. Problem noted by Pascal Speck. 15101 - waitpid(): Corrects two problems when CONFIG_SCHED_HAVE_PARENT + 15102 CONFIG_SCHED_CHILD_STATUS are enabled: (1) Was erroring out if the 15103 waited for task had already exited, and (2) was not freeing resources 15104 when a wait was completed. From Boris Astardzhiev. 15105 15106 * File System/Block and MTD Drivers: 15107 15108 - VFS poll(): Fix timeout calculation. From Jim Paris. 15109 - VFS poll(): Fix poll for regular files and block devices. Open Group 15110 documentation says that poll (and select) support regular files and 15111 that 'Regular files shall always poll TRUE for reading and writing'. 15112 From Jussi Kivilinna. 15113 - VFS epoll(): Fix epoll_wait function. From Simon Piriou. 15114 - Smart FS: Fix wrong freeing of device structure and use-after-free 15115 issues on error paths. From Jussi Kivilinna. 15116 - MTD FLASH drivers: The byte write method of several drivers had a 15117 cloned error: It was not locking the bus while performing byte write 15118 operations. 15119 - MTD M2PX: If we READ while a write/erase is pending, the command is 15120 ignored and the write/erase continues. If we dont catch this situation 15121 we will return garbage to the user because the flash will not execute 15122 the command. So READ MUST wait for write completion, and before that, 15123 the bus must be locked since it's a precondition to calling 15124 waitwritecomplete(). From Sebastien Lorquet. 15125 - MTD FLASH drivers: Clone Sebastien Lorquet's m25px change to at25, 15126 is25xp, ramtron, and sst25xx. 15127 - MTD W25: Add missing locking and fix SPI_SELECT usage for 15128 w25_unprotect. From Jussi Kivilinna. 15129 - MTD W25: Wait for BUSY flag to clear in w25_readid and 15130 w25_unprotect. W25Q128 datasheet says that all instructions expect 15131 'Read Status Register' and 'Erase/Program Suspend' are ignored when 15132 BUSY flag in status register is '1'. Therefore wait for busy flag to 15133 clear in w25_readid() and w25_unprotect(). From Jussi Kivilinna. 15134 - Automounter: FS_AUTOMOUNTER should depend on SCHED_LPWORK. From 15135 Nickolay Semyonov. 15136 15137 * Networking/Network Drivers: 15138 15139 - TCP Listen: Throw error when error happens in the tcp_listen 15140 function. From Roland Takacs. 15141 - Nework Device Management: Do not search net device when all-zeros 15142 address is used. From Roland Takacs. 15143 - Network Device Management: Fix a error in netdev_register(); it was 15144 not handling device names properly when TUN is the only network device. 15145 - Network Device Management: Fix netdev_dev_lladdrsize(). In some 15146 configurations, it could return the wrong size for the address of a 15147 packet radio. 15148 - Network Device Management: Fix typo for 802.11 devices in 15149 netdev_register(). Was being masked before because depended on 15150 CONFIG_NET_MULTLINK. 15151 - TUN Driver: Use critical section instead of semaphore in 15152 tun_ifdown(). From Masayuki Ishikawa. 15153 - TUN Driver: Do all polling on worker thread. Otherwise, the stack 15154 gets very deep. 15155 - TUN Driver: Currently cannot support TAP mode unless Ethenet is 15156 enabled. 15157 - netdb: Fixed buffer size used for sending DNS queries should depend 15158 on the configured DNS name size. From Ritjaina. 15159 - UDP networking: The TTL (time to live) was not being set in the IPv4 15160 or IPv6 header unless the UDP socket was bound. 15161 - UDP Networking: Fix a copy-paste error that could effect networking 15162 when both IPv4 and IPv6 are enabled. 15163 - UDP Networking: When upd_input() cannot process a packet, it returns 15164 ERROR so that network drivers may try calling ipv4_input() later. In 15165 this case, it must also set d_len to zero. Otherwise, all network 15166 drivers will assume tht there is also an outgoing packet. This 15167 results in a gratuitous ARP. 15168 - TCP Networking: Correct some issues that prevent TCP from working 15169 correctly when both IPv4 and IPv6 are enabled. 15170 - TCP Networking: TCP disconnection callbacks are not retained in a 15171 list. This will support multiple callbacks per lower-level TCP 15172 connection structure. That is necessary for the cae where a socket is 15173 dup'ed and shares the same lower-level connection structure. NOTE: 15174 There still needs to be a call to tcp_start_monitor() when the socket 15175 is dup'ed. 15176 - TCP Networking: Start the network monitor for a socket when a TCP 15177 socket is dup'ed. 15178 - TCP Networking: If one of the dup'ed socket's is closed, then network 15179 monitor resources associated with that one socket must be recovered. 15180 Also, in the event that socket is being used on one thread, but then 15181 closed on another, any threads waiting for events from the socket 15182 should be informed of the closure. That latter requirement is not 15183 implemented because current data structures do not support it. 15184 - TCP Networking: Fix a race condition. The accept() operation is 15185 performed with the network locked. However, the network is unlocked 15186 BEFORE the connected state is set. Therefore, a context switch may 15187 occur and the socket may no longer be connected when it is marked so. 15188 Noted by Pascal Speck. 15189 - Network routing tables: Fix a compilation error when IPv6 and 15190 routing are enabled. 15191 - Network procfs: Fix some spacing when both IPv6 and IPv4 are enabled. 15192 - Network Local Sockets: Fix accept for local stream sockets. From 15193 Jussi Kivilinna. 15194 - Network Local Sockets: Fix server lc_waitsem overflow. From Jussi 15195 Kivilinna. 15196 - IPv6 Networking: Remove comparisons to the address with all ones 15197 set. IPv6 does not support broadcast addresses and certainly not in 15198 that form. Replace with multicast addresses beginning with 0xff02. 15199 - ICMPv6 Networking: Fix a compilation issue with 15200 CONFIG_NET_ICMPv6_AUTOCONF=y. From Masayuki Ishikawa. 15201 - Networking: Fix net_lock returning ERROR when instead of real error 15202 code on failure. From Jussi Kivilinna. 15203 - IGMPv2 Networking: Remove special support for interrupt level 15204 processing (there is none) and fix some timer cancellation logic. In 15205 many files, correct comments. There is no interrupt level processing 15206 in the networking layer. 15207 15208 * Wireless/Wireless Drivers: 15209 15210 - IEEE 802.15.4 MAC: Need counting protection on the logic that 15211 releases the notification resources. Otherwise, notification handlers 15212 may be operating with a stale pointer. 15213 - IEEE 802.15.4 MAC: Improves internal timer logic to handle work 15214 serially. Before, the MAC timer used a watchdog to schedule work with 15215 the high priority worker queue. However, since everything in the MAC 15216 is supposed to be serialized through the use of the high priority work 15217 queue, but the timer uses a watchdog, there are some unintended 15218 consequences. To simplify, we now use the delayed work feature of the 15219 work queue. From Anthony Merlino. 15220 - IEEE 802.15.4 Network Driver: Update RX statistics in network driver. 15221 - IEEE 802.15.4 MRF24J40 Driver: Minor timing fix.

Also reserve two bytes at 15236 the end of the frame for the FCS. 15237 - 6LoWPAN: Fixes needed when extended addressing is enabled; broke short 15238 addressing. Loopback driver needs to initialize the MAC meta data; 15239 Address decompression logic must have the MAC address to handle the 15240 most common compression cases. Fix a src/dest address confusion and 15241 other addressing problems. 15242 - 6LoWPAN: Add missing IPv6 address creation to HC1 decode logic. Fix a 15243 typo in an index that prevented use with HC1 and extended addresses. 15244 - 6LoWPAN: TCP logic was not obeying MTU packet size limitations. 15245 - 6LoWPAN: Major re-architecting of TCP logic to properly handle TCP 15246 stuff like ACKs and TDP windowing which were not properly covered in 15247 the initial design. 15248 - 6LoWPAN: HC06, copy TCP header as though it were data. TCP packet 15249 reassembly now seems to work OK. 15250 - 6LoWPAN: Fix duplicate and bad memcpy in loopback driver. 15251 - 6LoWPAN: Fix a misconception about HC06 16-bit IPv6 address 15252 compression. 15253 - 6LoWPAN: TCP send logic was returning a failure in one case when, in 15254 fact, the send was successful. 15255 15256 * Common Drivers: 15257 15258 - USB MSC: Use struct instead of pointer to the struct as sizeof 15259 argument in memset in usbmsc.c. Otherwise it leads to error: argument 15260 to sizeof in memset call is the same pointer type struct usbmsc_lun_s 15261 * as the destination. From Oleg Evseev. 15262 - USB MSC: Add missing logic to define endpoints. The composite 15263 changes broke the the non-composite, USB MSC only case because it omitted the critical setup when USB MSC was not part of the composite. 15264 - USB CDC/ACM. Fix several known problems resulting from merge of USB 15265 composite device. That merge now breaks some of the non-composite USB 15266 devices. 15267 - Button Driver: Interrupts weren't enabled since nothing updates them 15268 after btn_poll() marks the file descriptor structure as being polling. 15269 From Jan Pobrislo. 15270 - ADC Driver: Fix some data alignment issues in the ADC driver. 15271 - I2C Drivers: Handle I2C_TRANSFER return value consistently. Some I2C 15272 peripherals transfers return zero on success, others number of 15273 completed transfers. Make drivers robust against this. From Juha 15274 Niskanen. 15275 - COMP Driver: Fix compilation errors when poll disabled. From Mateusz 15276 Szafoni. 15277 15278 * Simulation: 15279 15280 - Simulation: Fix mkdir issue in GNU target.

From Jussi 15283 Kivilinna. 15284 15285 * ARM: 15286 15287 - ARM: The older ARM7 and ARM9 configurations were determining CFLAGS 15288 based on the GCC version 4.x.x or not. That needx to be extended for 15289 5.x.x and 6.x.x which also behave like 4.x.x. 15290 15291 * ARMv7-M: 15292 15293 - Fixed ARMv7-M Toolchain setting. Cortex-M4 only have Single 15294 Precision FPU. From Hidetaka Takano. 15295 - ARMv7-M syscall logic: Clear bit 0 in PC settings. Bit 0 is the 15296 thumb mode indication and should not be set in the PC. This extra bit 15297 has not caused problems in the past, but seeing it set in the PC is 15298 unnerving. 15299 15300 * Expressif ESP32: 15301 15302 - Fix ESP32 gpio enable reg and default UART pin. Modify default UART 15303 pin for ESP-WROOM-32. Fix gpio enable reg. From Sungki Kim. 15304 15305 * Microchip/Atmel SAMD21 Drivers: 15306 15307 - SAMD21: Fix some SPI-related issues. From Matt Thompson. 15308 - SAMD21 SPI: I was having issues with the bus freezing up .. slaves 15309 holding SDL low.. so I rewrote a good portion of the interrupt logic 15310 based on the application notes from Atmel. One major improvement is 15311 using the RXNACK flag in the STATUS register, which indicates that no 15312 device responded to an address packet. Assuming that the chip will 15313 always give an interrupt status, I believe it's possible to eliminate 15314 the timer as well. From Matt Thompson. 15315 - SAMD/L21: Need to preserve errno value across syslog() call. 15316 - SAMD21: Changes needed to get USB working. From Matt Thompson. 15317 15318 * Microchip/Atmel SAMv7 Drivers: 15319 15320 - SAMv7 TWIHS: TWIHS driver add reference counting. From David Sidrane. 15321 - SAMv7 CAN: We discovered a problem with the samv7 mcan driver which 15322 results, under some circumstances, in a very high CPU load. The 15323 problem occurs, and is easily reproducible, if the device is connected 15324 to a CAN network with a wrongly configured CAN speed (baud rate). In 15325 our tests we set the CAN speed of the device to 1000000 and the speed 15326 of the other CAN nodes to 500000. The device is restarted and sends a 15327 CANopen "bootup message" to the CAN network. This results in huge 15328 amount of errors messages on the CAN bus, probably because of the CAN 15329 feature for acknowledging error messages. The error messages can�t be 15330 read by the device because of the misconfigured CAN speed, instead the 15331 CAN chip reports lots of errors, which are reported to the application 15332 which uses the CAN driver (CONFIG_CAN_ERRORS is enabled). The CAN 15333 errors are reported from the CAN chip via interrupts and thus the 15334 interrupt load is very high in this scenario. To fix the problem the 15335 driver now disables each RX error interrupt after it is occurred. The 15336 RX error interrupts are turned back on if at least one CAN message is 15337 received successfully. From Stefan Kolb. 15338 - SAMv7 CAN: I discovered while working on the SAMV7 mcan driver that 15339 the implementation of the CAN error handling is suboptimal. In the 15340 current implementation the many errors are implemented as pending 15341 errors. But those errors are not pending, the errors occurred and are 15342 gone directly afterwards. This commit changes the described behavior 15343 and simplifies the handling of CAN errors. From Stefan Kolb. 15344 15345 * Microchip/Atmel SAMv7 Boards: 15346 15347 - SAMv71-XULT: Fix MRF24J40 interrupt GPIO number. 15348 15349 * NXP/Freescale Kinetis: 15350 15351 - Kinetis MPU: Disable MPU when not in protected mode. The hardware 15352 reset state of the the MPU precludes any bus masters other then DMA 15353 access to memory. Unfortunately USB and SDHC have there own DMA and 15354 will not have access to memory in the default reset state. This change 15355 disabled the MPU if present on system startup. From David Sidrane. 15356 - Kinetis MPU: Fixed warning for kinetis_mpudisable. Missing header 15357 file added. From David Sidrane. 15358 - Kinetis SIM: Ensure isolation of clock dividers for 0 value case. 15359 This fixes a bug were a SoC does not have a clockdivN register and 15360 passes a 0 for the init value. This prevents overflow of the 0 15361 decremented to -1 (0xffffffff) spilling over to other clockdivN 15362 fields. From David Sidrane. 15363 15364 * NXP/Freescale i.MX6 Drivers: 15365 15366 - i.MX6: Fix a wrong parameter passed when calling irq_attach() in 15367 imx_serial.c. From Masayuki Ishikawa. 15368 - Based on Masayuki's change, I review all serial driver vector 15369 attachment.

"AN 4667 - STM32F7 15383 Series system architecture and performance" recommends to disable 15384 read-modify-write on DTCM: "If the DTCM-RAM is used as data location 15385 and the variables used are byte or/and halfword types, since there is 15386 no ECC management in this RAM on the STM32F7 Series, it is recommended 15387 to disable the read-modify-write of the DTCM-RAM in the DTCM interface 15388 (inthe DTCMCR register) to increase the performance." From Jussi 15389 Kivilinna. 15390 15391 * STMicro STM32 Drivers: 15392 15393 - STM32 TIM3/4 are always 16-bits; never 32-bits.

From Juha 15404 Niskanen. 15405 - STM32 F1 RTC fixes: (1) Compile issues because of missing RTC_MAGIC 15406 #defines, (2) missing functionality based on RTC_MAGIC in RTC based on 15407 stm32_rtcounter.c, (3) IRQ setup from up_rtc_initialize was later 15408 reset in up_irqinitialize, (4) write access to backup registers 15409 without enabling access to backup domain, (5) possible races in 15410 set/cancel alarm. tested with STM32F103C8 only. device now wakes up 15411 from forced STANDBY mode by alarm. From Leif Jakob. 15412 - STM32/STM32 L4 PWM: While attempting to output a 70 MHz square wave 15413 from the timer output of a STM32 clocked at 140 MHz, found that the 15414 reload calculation was off by one. This correction does allow the 15415 output up to 70 MHz. I am not sure this affects most users 15416 generating slow PWM but for frequencies close to the PCLK, the 15417 difference becomes significant. From JM. 15418 - STM32 L4 I2C: Set I2C SDA and SCL pins to open drain mode. From Pekka 15419 Ervasti. 15420 - STM32 L4 I2C: I2C4 was writing to wrong RCC registers. From Juha 15421 Niskanen. 15422 - STM32 L4 DAC: Report transfer as completed in DMA callback. Without 15423 this even O_NONBLOCK writes block the calling task if DAC was using 15424 DMA.

From Eetu 15432 Nevalainen. 15433 - STM32 F7 Ethernet: Fix typo in header; Add memory sync barrier 15434 between writing to DMA TX descriptor and restarting DMA TX. Avoid 15435 calling work_queue on pollwork if it's already queued, just skip a 15436 poll cycle instead. Nucleo-144: Fix RMII TXD1 signal, connected to 15437 PB13 not to PG14. From savinz. 15438 - STM32 F7: Added missing config option for register value debugging. 15439 From Titus von Boxberg. 15440 - STM32 F7: No FSMC, only FMC for STM32F7. From Titus von Boxberg. 15441 - STM32 F7: HEAP2 depends on CONFIG_ARCH_HAVE_HEAP2, not on particular 15442 FMC RAM type. From Titus von Boxberg. 15443 - STM32 F7: STM32_RCC_DCKCFGR2 has nothing to do with PLLI2S; PLLI2S is 15444 not dependent on LTDC, instead on SAICLK1/2 generated from PLLI2S. 15445 From Titus von Boxberg. 15446 - STM32F7: Some STM32F7 builds failed in build testing due to undefined 15447 STM32_SRAM1_BASE. I think that is because stm32_allocateheap.c was 15448 not including chip/stm32_memorymap.h. 15449 - STM32 F7: dcache write-buffed mode is used (not write-through) buffer 15450 alignment is required for DMA transfers because a) 15451 arch_invalidate_dcache could lose buffered writes data and b) 15452 arch_flush_dcache could corrupt adjacent memory if the buffer and the 15453 bufflen, are not on ARMV7M_DCACHE_LINESIZE boundaries.

From Ivan Ucherdzhiev. 15474 15475 * Build System 15476 15477 - Fix -Werror=implicit-fallthrough on gcc7. From Julien Lecoeur. 15478 - configs/Board.mk: Remove comment form end of line. In windows native 15479 build, it appears to be trying to make that an extra parameter to the 15480 AR command. From Jeff. 15481 - configs/Board.mk: Remove quotes from CONFIG_ARCH_FAMILY. Causes 15482 problems with Windows native build. From Jeff. 15483 - Makefile.win would only create uboot images for ARM. MIPS support 15484 also needed. From Lwazi Dube. 15485 15486 * C Library/Header Files: 15487 15488 - C++: Fix C++ __guard implementation for ARM. The standard C++ ABI 15489 that most platforms follow defines __guard to be 64 bits. The existing 15490 implementation of libxx_cxa_guard.cxx follows this. However, the 15491 32-bit ARM C++ ABI defines it as 32 bits instead, and changes the 15492 meaning slightly so only the lowest bit is used. This matters because 15493 GCC creates guard symbols without regards to what libxx_cxa_guard.cxx 15494 says. So on ARM, gcc allocates 4 bytes, but __cxa_guard_release 15495 writes 8 bytes, zeroing out another unlucky variable nearby. Fix it 15496 by special-casing 32-bit ARM in libxx_cxa_guard. From Jim Paris. 15497 - C++: In cwchar it uses CONFIG_LIBC_WCHAR to only export the wc/mb 15498 functions. When a build does not want to use wide or multibyte char 15499 CONFIG_LIBC_WCHAR is not set. Therefore we should to only export the 15500 wc/mb functions when defined. Regardless of the stat of 15501 CONFIG_LIBC_WCHAR the non mb/wc definitions such as mbstate_t, 15502 wint_t, wctype_t need to be exported.

From Alan Carvalho de Assis. 15505 - C Library: (1) Fix an error in mkstemp() the could result in an 15506 infinite loop. (2) Fix for wrong output in some cases. For Example: 15507 (a) input: "FILEXX", output: "FILE00" and repeats same output for 15508 further invocations of mkstemp(). But, the output has to be FILE01, 15509 FILE02, ...., FILEZZ. (b) input: "FILEXXXXXX", output: "FILE100000", 15510 for next invocation "FILE200000" and so on. But it's good, if the 15511 output goes like FILE000001, FILE000002, ..., FILE000101, ...

Hopefully this will end awkward problems when you Control-C 15532 out of a build and libapps.a is deleted. 15533 - platform/Makefile: More attempts to fix for Windows native build. 15534 Backslash as a delimiter causes problems in pattern subsitutions. 15535 15536 * NSH: apps/nshlib: 15537 15538 - NSH network initialization: Fix some ieee 802.15.4 initialization 15539 logic. It should not set the saddr or panid; those cannot be 15540 hard-coded but must come from the coordinator. Re-factor a function 15541 that has gotten too big and too complex. Do not set the IP address 15542 for 6loWPAN. The 6loWPAN stack uses IP address that derive from the 15543 ieee 802.15.4 addressing and cannot be (safely) configured by the user. 15544 - NSH Library: Fix copy-paste typo in nsh_usbconsole.c.

From 15603 Jeff. 15604 15605NuttX-7.23 Release Notes 15606------------------------ 15607 15608The 123rd release of NuttX, Version 7.23, was made on December 4, 2017, 15609and is available for download from the Bitbucket.org website. Note 15610that release consists of two tarballs: nuttx-7.23.tar.gz and 15611apps-7.23.tar.gz. These are available from: 15612 15613 https://bitbucket.org/nuttx/nuttx/downloads 15614 https://bitbucket.org/nuttx/apps/downloads 15615 15616Both may be needed (see the top-level nuttx/README.txt file for build 15617information). 15618 15619Additional new features and extended functionality: 15620 15621 * Core OS: 15622 15623 - sem_open() should return SEM_FAILED on any failures. This is change 15624 in the POSIX specification since the original sem_open() was written 15625 so many years ago. 15626 - exec(): The non-standard interface exec() is now enshrined as a 15627 official NuttX API. I really dislike doing this but I think that 15628 this is probably the only want to load programs in the protected 15629 mode. It is currently used by some example code under apps/ that 15630 generate their own symbol tables for linking. Other file execution 15631 APIs relay on a symbol table provided by the OS. In the protected 15632 mode, the OS cannot provide any meaning symbol table for execution 15633 of code in the user-space blob so that is they exec() is really 15634 needed in that build case. And, finally, the interface is 15635 completely useless and will not be supported in the KERNEL build 15636 mode where the contrary is true: An application process cannot 15637 provide any meaning symbolic information for use in linking a 15638 different process. 15639 - OS Internal Functions: Rename many OS internal functions so it is 15640 clear that they are not part of the application interface. All 15641 internal functions with the sem_* prefix became nxsem_*, sig* become 15642 nxsig_*, mq_* become nxmq_*, etc. 15643 - Cancellation Points: Add new cancellation point interface, 15644 check_cancellation_point(). 15645 - Signals: Add logic to wake up a thread that is waiting on a signal 15646 if it is canceled. 15647 - sigtimedwait(): Add logic to suppress the wait if there is a 15648 pending cancellation. 15649 - clock_nanosleep(): Implement clock_nanosleep(). nanosleep() is now 15650 reduced to a libc wrapper around clock_nanosleep(). 15651 - task_delete(): Do not permit user applications to delete kernel 15652 threads. 15653 - kthread_create(): Rename kernel_thread() to kthread_create() for 15654 better naming consistency with task_create() and kthread_delete(). 15655 - boardctl(): Remove the BOARDIOC_GRAPHICS_SETUP command. 15656 - TCB: Move POSIX thread specific data from pthread TCB to common TCB 15657 structure. This change allows using pthread_getspecific and 15658 pthread_setspecific from main thread. Patch also enables using 15659 pthread data with config option CONFIG_DISABLE_PTHREAD=y. From Jussi 15660 Kivilinna. 15661 - mm: Remove the CONFIG_GRAN_SINGLE configuration option. It adds no 15662 technical benefit (other than some minor reduction in the number of 15663 interface arguments) but adds a lot of code complexity. Better 15664 without it. 15665 - mm: Add a function to get information about the state of the 15666 granule allocator. This is the moral equivalent of mallinfo(). 15667 15668 * File Systems/Block and MTD Drivers 15669 15670 - MT25Q Serial FLASH: Add support for Micron MT25Q series MT25Q128. 15671 From Sebastien Lorquet. 15672 - MX35LFxGE4AB: Add an MTD driver for Macronix MX35LFxGE4AB serial 15673 NAND flash. From Ekaterina Kovylova. 15674 - FileMTD: Add block device MTD interface. Block MTD interface 15675 allows using block device directly as MTD instead of having to use 15676 file-system in between. NOTE that this provides the opposite 15677 capability of FTL which will let you use an MTD interface directly 15678 as a block device. From Jussi Kivilinna. 15679 - BCH: The character driver to block device access now supports an 15680 IOCTL to get the geomtry of the underlying block device. 15681 - mkfatfs: Remove mkfatfs from the OS. This is a user-space 15682 application and belongs in apps, not in the OS. 15683 - procfs: Implements procfs /proc/fs/blocks and /proc/fs/usage files, 15684 replacing the NSH df command. Also implements procfs /proc/fs/mount 15685 file, replacing the NSH mount command when there are no arguments. 15686 - procfs: Add /proc/meminfo. This is an alternative way to get the 15687 information that was previoulsy available in apps/system/free. 15688 apps/system/free was removed beause it made illegal calls into the 15689 OS violating the portable interface. This new procfs entry provides 15690 the same information with no such violation. it also provides 15691 information about the kernel heap (formerly /proc/kmm), about the 15692 use of program memory(formerly /proc/progmem). And also information 15693 for the page table usage in the KERNEL build. 15694 - UserFS: Adds the UserFS client and of the UserFS feature in 15695 general. Initially used Unix domain local sockets instead of 15696 message queues. Easier to transfer big data in local sockets than 15697 message queues. However, that lead to certain inescapable deadlock 15698 conditions So the IPC was converted to UDP LocalHost loopback 15699 sockets. The problem with the local sockets is that they do require 15700 operations on the top level pseudo-file system inode tree. That 15701 tree must be locked during certain traversals such as enumerate 15702 mountpoints or enumerating directory entries. This conversion is 15703 unfortunate in the sense that Unix local domain sockets are 15704 relatively lightweight. LocalHost UDP sockets are much heavier 15705 weight since they rely on the full UDP stack. 15706 15707 * Graphics/Display Drivers: 15708 15709 - Framebufer character driver: Add framebuffer character device driver. 15710 - LCD Framebuffer: Add support for a generic front-end that will 15711 convert any LCD driver into a framebuffer driver. 15712 - Framebufer character driver: Include support for LCD drivers that 15713 use a simulated framebuffer and must receive explicit notification 15714 when there is an update to a region in the framebuffer. 15715 - LCD: Make LCD driver configuration indepently selected from NX 15716 graphics configuration. This makes things awkward and loses some 15717 error checking but is a necessary step in order to make LCD drivers 15718 usable when the NX graphics system is disabled. 15719 15720 * Networking/Network Drivers: 15721 15722 - Networking: Add implementation of logic for SIOCGIFCONF and 15723 SIOCGLIFCOF IOCTL commnds. 15724 - Network IOCTLs: Add support for the SIOCGIFBRDADDR ioctl() command. 15725 - Routing Tables: Permit IPv4 and IPv6 routing tables to be of 15726 different sizes. 15727 - Routing Tables: Adds support for read-only routing tables. Prior 15728 to this change, routing tables were only support in RAM and had to 15729 be initialized with explicit logic to add the necessary routes to 15730 the routing table. With this change, routes may be defined in the 15731 pre-initialized, read-only routing table provided by the 15732 board-specific logic. 15733 This would be particularly useful, for example, in the case where 15734 there is only a single network adaptor and you want all output 15735 packets to go to the single adaptor in all cases. So for that 15736 behavior you could add a read-only routing table to the 15737 board-specific long that contains a single entry, the default route: 15738 0.0.0.0/0. 15739 - Routing Tables. Added support for routing tables in files in a file 15740 system. This might be useful for customized, per-unit routing 15741 tables. There are two issues with it however: 15742 1. Reading from file system on a per packet basis could be slow. I 15743 think it probably should have a small, in-memory cache of most 15744 frequently used routes for good problem. 15745 2. Currently the delroute logic is disabled due to a problem with 15746 the design. NuttX does not currently support truncate(). 15747 Therefore, it is not possible to delete entries from the routing 15748 table file. In this current implementation, that leaves the last 15749 entry intact at the end of the file. An alternative design 15750 might include a tag on each record to indicate if the record is 15751 valid or not. That would work but would add complexity to the 15752 other routing table functions. 15753 - Routing Tables: Add support for an in-memory routing table cache in 15754 order to improve performance when the routing table is retained in a 15755 file. The cache holds the most recently used routing table entries 15756 and so can eliminate some file access. Flush the in-memory cache 15757 when any entry is deleted from the routing table. When a router 15758 matching an IP address is found, add the routing table entry to the 15759 cache. 15760 - Routing Tables: Add logic to mark a route as most-recently-used in 15761 the route cache. 15762 - ICMP: This change adds support for semi-standard IPPROTO_ICMP 15763 AF_INET datagram sockets. This replaces the old ad hoc, nonstandard 15764 way of implementing ping with a more standard, socket interface. 15765 - ICMPV6: This commit adds support for semi-standard IPPROTO_ICMP6 15766 sockets. This is a replacement for the non-standard ICMPv6 ping 15767 support that violated the portable POSIX OS interface. 15768 - ICMPv6: Add option to manually specify router prefix in router 15769 advertisement message. From Sakari Kapanen. 15770 - Local Sockets: This commit modifies the Unix domain local socket 15771 design. Local sockets are built on top of pipes. The Local socket 15772 implementation maintained file descriptors to interrupt with the 15773 pipes. File descriptors have the bad property that they are valid 15774 only while running on the thread within the task that created the 15775 local socket. 15776 As a policy, all internal OS implementations must use "detached" 15777 files which are valid in any context and do not depend on the 15778 validity of a file descriptor at any point in time. This commit 15779 converts the usage of file descriptors to detached files throughout 15780 the local socket implementation. 15781 15782 * Wireless Networking/Wireless Drivers: 15783 15784 - IEEE-802154: Adds support for receiving MAC events via IOCTL through 15785 socket interface. From Anthony Merlino. 15786 - IEEE-802154: Simplifies notify() and rxframe() calls to a single 15787 notify() call. dataind's and all other "notifs" are now "primitives" 15788 which aligns with standard terminology From Anthony Merlino. 15789 - MAC802154: Add support for getting promiscuous mode state From 15790 Anthony Merlino. 15791 - MAC802154 Character Driver: When in promiscuous mode, the char 15792 driver sends the entire frame, including the MAC header. This 15793 change adds an offset field indicating the header-payload boundary. 15794 It is set to 0 when not in promiscuous mode as the header is not 15795 passed to the application 15796 - 6LoWPAN: Remove CONFIG_NET_6LOWPAN_FRAMELEN. In this case where 15797 multiple radios are supported, this may not be a constant. 6LoWPAN 15798 now always queries the driver to get the maximum frame length. 15799 - 6LoWPAN: Support sending to a router that is on-link and may be 15800 able to forward the packet for us if the destination is not 15801 reachable directly. From Anthony Merlino. 15802 - XBee: Adds XBee S2C (802.15.4 firmware) support. XBee driver 15803 emulates mac802154 interface. From Anthony Merlino. 15804 15805 * Other Common Device Drivers: 15806 15807 - PowerLED: Add upper-half driver for high power LED driver (powerled) 15808 From Mateusz Szafoni. 15809 - RTC Driver: Add periodic alarms to upper and lower halves. From 15810 Juha Niskanen. 15811 - Pipes: Fix writing large buffers not triggering POLLIN for reader 15812 poll. From Jussi Kivilinna. 15813 - USB CDC/ACM Device: Add support for RX flow control to the CDC/ACM 15814 driver. 15815 - USB CDC/ACM Device: Add support for flow control TERMIOs in CDC/ACM 15816 driver. 15817 - USB RNDIS Device: Add RNDIS-over-USB driver. From Sakari Kapanen 15818 with added Hi-Speed support from Masayuki Ishikawa. 15819 - Loop Driver: Don't use file descriptors... Use the internal file 15820 system interfaces so that the loop device can be shared across 15821 threads. 15822 - APA102 LED controller: Add driver for APA102 LED controller. These 15823 LEDs are used on LED Strips and are controlled over SPI. 15824 - INA219. Add INA219 Driver. The INA219 is a combined voltage and 15825 current sensor that can measure up to 26 volts and a current that 15826 depends on an external shunt resistor. Connection happens via 15827 i2c/smbus and the chip features a power supply rail that is 15828 independent from the measured voltage, so it can measure low 15829 voltages. Right now it measures bus voltage and current, and does 15830 not use the internal calibrated current reading, nor the available 15831 power measurement. From Sebastien Lorquet. 15832 - PCA9555: The IRQ subsystem now supports passing a void * parameter 15833 to IRQ handlers. Use that method to support multiple PCA9555 15834 devices, by passing a pointer to the device to the board defined IRQ 15835 handler. Now the CONFIG_ for multiple PCA devices just allocates 15836 device structures dynamically instead of statically when not enabled. 15837 The same interrupt handler is entered with the device structure 15838 parameter in all situations, multiple or single PCA. One should 15839 still be careful if multiple PCA devices share the same IRQ. From 15840 Sebastien Lorquet. 15841 - APDS-9960: Add driver for the APDS-9960 gesture sensor. From Alan 15842 Carvalho de Assis. 15843 - MAX7219: Add support to MAX7219 LED Matrix as LCD interface. From 15844 Alan Carvalho de Assis. 15845 - WM8774: Add WM8774 audio DAC support. From Masayuki Ishikawa. 15846 - Nunchuck: Add Nintendo Wii Nunchuck driver. From Alan Carvalho de 15847 Assis. 15848 15849 * Simulation 15850 15851 - Simulation: Add a configuration for non-graphical testing of the 15852 frambuffer character driver using apps/example/fb. 15853 - Simulation: Add a configuration for testing the UserFS using 15854 apps/examples/userfs. 15855 15856 * Broadcom BCM2708: 15857 15858 - BCM2708: Add enough infrastructrue (more stubs) to get a clean 15859 compilation of the Pi Zero configuration (with many undefined things 15860 at link time). This includes several register definition header 15861 files (some from Alan Carvalho de Assis), basic interrupt handling 15862 logic, boot-up files, GPIO support, tickless timer, build and 15863 configuration logic 15864 15865 * Broadcom BCM2708 Boards: 15866 15867 - Raspberry Pi Zero. Basic board support at configs/pizero. Untested 15868 in this release and still some remaining issues. 15869 15870 * Infineon XMC4xxx Boards: 15871 15872 - XMC4500-Relax: Add config for UART3 on RXD P0.0 and TXD P0.1 pins. 15873 From Alan Carvalho de Assis. 15874 15875 * NXP Freescale LPC17xx Boards: 15876 15877 - Open1788: Add initialization of Framebuffer driver. Add 15878 configuration for testing the framebuffer driver. 15879 15880 * NXP Freescale LPC43xx Drivers: 15881 15882 - LPC43xx: Add LPC43xx CAN driver. From Alexander Vasiljev. 15883 15884 * NXP Freescale LPC43xx Boards: 15885 15886 - MCB1700: Add support for Keil MCB1700 board. From Alan Carvalho de 15887 Assis. 15888 - Open1788: Add support for the discrete joystick driver. 15889 - Open1788: Add a configuration for testing pdcurses with discrete 15890 joystick. 15891 15892 * On Semiconductor LC823450 15893 15894 - LC823450: Add ADC driver and watchdog drivers. From Masayuki 15895 Ishikawa. 15896 - LC823450: Add IPL2 support. From Masayuki Ishikawa. 15897 - LC823450: Add I2S support. From Masayuki Ishikawa. 15898 - LC823450: Add auto LED for CPU activity. From Masayuki Ishikawa. 15899 15900 * On Semiconductor LC823450 Boards 15901 15902 - LC823450-XGEVK: Enable ADC and watchdog driver. From Masayuki 15903 Ishikawa. 15904 - LC823450-XGEVK: Add IPL2 support. From Masayuki Ishikawa. 15905 - LC823450-XGEVK: Add WM8774 support. From Masayuki Ishikawa. 15906 - LC823450-XGEVK: Add auto LED support. From Masayuki Ishikawa. 15907 - LC823450-XGEVK: Enable CONFIG_SMP for audio. From Masayuki Ishikawa. 15908 - LC823450-XGEVK: Add rndis configuration. From Masayuki Ishikawa. 15909 15910 * STMicro STM32: 15911 15912 - ARM Kconfig: Add support for classic ARM11 architecture selections. 15913 - STM32 Tickless: Removes the restriction to 16-bit counts when a 15914 32-bit timer is used for tickless operation on the stm32. As it 15915 was, the restriction is very limiting, especially if one wants high 15916 granularity and large achievable intervals and has the hardware 15917 (namely the 32bit timers) available. From Rajan Gill. 15918 - STM32 L4 Kconfig: Add some L486 and L496 chips. From Juha Niskanen 15919 - STM32 F7: Adds architecture support for the STM32 F72x and F73x 15920 families. From Bob Feretich. 15921 - STM32 F7: Allow changing voltage output scaling setting and 15922 prevents enabling over-drive mode for low frequencies (STM32 F74xx, 15923 75xx, 76xx, 77xx). From Jussi Kivilinna. Changes replicated for 15924 the 72xx and 73xx families. 15925 15926 * STMicro STM32 Drivers: 15927 15928 - STM32 ADC: Added support for ADC's IO_ENABLE_TEMPER_VOLT_CH ioctl 15929 on STM32F10XX and STM32F20XX. From Dmitriy Linikov. 15930 - STM32 Wakeup: Add logic for enabling wakeup pins. From Oleg Evseev. 15931 - STM32 PWR: Adds stm32_pwr_getsbf and stm32_pwr_getwuf functions 15932 that return the standby flag and the wakeup flag PWR power 15933 control/status register. From Oleg Evseev. 15934 - STM32 HRTIM: Sdd support for capture, chopper, deadtime and dump 15935 registers. From Mateusz Szafoni. 15936 - STM32 RTC: Canceling an alarm marks it as inactive. From Juha 15937 Niskanen 15938 - STM32 Serial: Add interface to get uart_dev_t by USART number, 15939 stm32_serial_get_uart(). From Juha Niskanen. 15940 - STM32 F33xx ADC: Initial ADC support for the STM32F33XX. From 15941 Mateusz Szafoni. 15942 - STM32 F33xx ADC: Add ADC DMA support to STM32F33 configuration. From 15943 Mateusz Szafoni. 15944 - STM32 L4 ADC: Port analog watchdog ioctl commands from the Motorola 15945 MDK. From Juha Niskanen 15946 - STM32 L4 ADC: Add option for routing ADC data to DFSDM, fix DFSDM 15947 DMA. From Juha Niskanen 15948 - STM32 L4 ADC: Add PM hooks from Motorola MDK 15949 - STM32 L4 FLASH: Add function for modifying device option bytes, 15950 From Juha Niskanen. 15951 - STM32 L4 DFSDM: Add peripheral support for digital filters for 15952 sigma-delta ADCs. Initial version. Timer trigger support is not 15953 completed and there is some issue with DMA. From Juha Niskanen. 15954 - STM32 L4 I2C: Port then STM32 F7 I2C driver to STM32 L4. STM32L4 I2C 15955 driver is in work-in-progress state (plentiful of TODOs and 15956 #warnings) and lags many features found in more up-to-date STM32 I2C 15957 drivers. The peripheral on STM32F7 and STM32L4 are identical except 15958 for L4's 'wakeup from stop mode' flag and STM32F7's I2C driver is in 15959 more 'ready to use' state. The I2C clock configuration is kept the 15960 same as before (I2CCLK = PCLK1 80 Mhz) instead of switching to 15961 STM32F7 arch default that is I2CCLK=HSI. Further work would be to 15962 add configuration option for choosing I2C clock source instead of 15963 current hard-coded default. From Jussi Kivilinna. 15964 - STM32 L4 RTC: Add up_rtc_getdatetime_with_subseconds 15965 - STM32 L4 RTC: Change maximum alarm time from 24h to one month. From 15966 Juha Niskanen. 15967 - STM32 L4 RTC: Add support for periodic interrupts with 15968 (experimental) CONFIG_RTC_PERIODIC. From Juha Niskanen. 15969 - STM32 L4 SDMMC: Add support for an SDMMC driver. From Miha Vrhovnik. 15970 - STM32 L4 Serial: Suspend serial for Stop mode. From Juha Niskanen. 15971 - STM32 L4 Serial/PM: STM32L4 serial PM interface improvements: 15972 Check rx/tx buffers for pending data in pmprepare. Remove adhoc PM 15973 interfaces and move serial suspend functionality behind CONFIG_PM. 15974 From Jussi Kivilinna. 15975 15976 * STMicro STM32 Boards: 15977 15978 - STM32F103-Minimum: Add board support for APA102 driver. From Alan 15979 Carvalho de Assis. 15980 - STM32F103-Minimum: Add ADC support on stm32f103-minimum board. 15981 From Alan Carvalho de Assis. 15982 - STM32F103-Minimum: Add support for LM75 in the stm32f103-minimum 15983 board. From Alan Carvalho de Assis. 15984 - STM32F103-Minimum: Add an ADPS-9960 example configuration. From 15985 Alan Carvalho de Assis. 15986 - STM32F103-Minimum: Add board support for MAX7219 LED Matrix 15987 controller. From Alan Carvalho de Assis. 15988 - STM32F103-Minimum: Add USB MSC device initialzation to 15989 stm32f103-minimum. From Alan Carvalho de Assis. 15990 - STM32F103-Minimum: Add framebuffer driver initialization for 15991 stm32f103-minimum board. From Alan Carvalho de Assis. 15992 - STM32F103-Minimum: Add Nunchuck board support for 15993 stm32f103-minimum board. From Alan Carvalho de Assis. 15994 - STM32F4 Discovery: Add support for JLX12864G display on STM32F4 15995 Discovery board. From Alan Carvalho de Assis. 15996 - Viewtool-STM32F107: Add support to auto-mount the procfs file system. 15997 - Photon: Support SPI1 and SPI3. From Anthony Merlino. 15998 - STM32F334-DISCO: Add lower half driver for high power LED 15999 (powerled). From Mateusz Szafoni. 16000 - STM32F334-DISCO: Add flash mode support for powerled driver. From 16001 Mateusz Szafoni. 16002 - STM32F334-DISCO: Add powerled example configuration. From Mateusz 16003 Szafoni. 16004 - STM32F334-DISCO: Add lower-half driver for SMPS (buck-boost onboard 16005 converter). From Mateusz Szafoni 16006 - Nucleo-F334R8: Add logic for zero latency high priority interrupts 16007 example. From Mateusz Szafoni. 16008 - Nucleo-F334R8: Add highpri example configuration. From Mateusz 16009 Szafoni. 16010 - STM32 F4 Discovery: Added support for the LIS3DSH accelerometer on 16011 the STM32F4 Discovery rev. C boards. From Florian Olbrich. 16012 - STM32 F4 Discovery: ROMFS for STM32F4 Discovery board. From Tomasz 16013 Wozniak. 16014 - STM32 F4 Discovery: Add a USB MSC configuration. From Alan Carvalho 16015 de Assis. 16016 - STM32 F4 Discovery: RNDIS support on STM32F4Discovery + DM-STF4BB. 16017 NOTE: MAC address for the host side starts 0xaa. This assignment 16018 scheme should be fixed later. From Masayuki Ishikawa. 16019 - STM32 F4 Discovery: Add STM32F4 Discovery board support for 16020 Nunchuck joystick. From Alan Carvalho de Assis. 16021 - STM3240G-EVAL: Add a configuration for testing the Framebuffer 16022 character driver using the LCD framebuffer front. 16023 - STM3240G-EVAL: Mount procfs if enabled. 16024 - STM3240G-EVAL: Add support for pdcurses and the pdcurses demo 16025 programs in the 'fb' configuration. 16026 - Clicker2-STM32: Adds SD card, automount, and syslog file 16027 support and fixes a few minor issues. From Anthony Merlino. 16028 - Clicker2-STM32: Adds support for USB RNDIS device. From Anthony 16029 Merlino. 16030 - Olimex STM32-H407: Add serial support on the on-board UEXT 16031 connector. Add USART6 for UEXT connector. Add nsh_uext 16032 configuration and README update. From Jan Pobr�slo. 16033 - Nucleo-F410RB: Add support for the nucleo-F410RB board. From 16034 Gwenhael Goavec-Merou. 16035 - STM32F429i-DISCO: Add framebuffer driver initialization. Add a 16036 framebuffer (fb) configuration. 16037 - STM32F429i-DISCO: Add logic to auto-mount procfs. Enable procfs in 16038 all configurations that use NSH. 16039 - STM32F429i-DISCO: Enable support for the STMPE811 touchscreen 16040 controller. Enable touchscreen and also the touchscreen testa at 16041 apps/examples/touchscreen in the fb configuration. 16042 - STM32F429i-DISCO: Convert NxWM configuration to use LTDC 16043 framebuffer driver instead of SPI serial. Also reduce number of 16044 layers from 4 to 1 in fb configuration. Only one layer is used. 16045 - STM32L476-MDK: Add support for the on-board LEDs. 16046 - Nucleo-L496ZG: Add DFSDM initialization. From Juha Niskanen 16047 - Nucleo-L496ZG: Add support for SDMMC driver. From Miha Vrhovnik. 16048 - Nucleo-L496ZG: Enable I2C4 bus with i2ctool in NSH configuration. 16049 From Jussi Kivilinna. 16050 - Nucleo-L496ZG: Make HSE on Nucleo-L496ZG default to enable USB. 16051 From Miha Vrhovnik. 16052 - Nucleo-F746ZG: Use the serial console over /dev/ttyACM0 by default. 16053 The Nucleo-F746ZG doesn't come with Arduio RS-232 shield, then it is 16054 better to use the serial over the /dev/ttyACM0 that is created 16055 automatically when the board is plugged in the computer. From Alan 16056 Carvalho de Assis. 16057 - Nucleo-144: Adds support for the Nucleo-144 boards with 16058 STM32F722ZE. From Bob Feretich. 16059 16060 * ZiLOG Z80 16061 16062 - z80/include: compiler.h, limits.h, types.h: Update SDCC/z80 files 16063 to include support for long long, inline, __FILE__, and __func__. 16064 16065 * C Library/Header Files: 16066 16067 - include/: Add stdnoreturn.h. Holds definitions for the C11 16068 noreturn keyword. Applies to C too. 16069 - include/netinet/tcp.h: Add trivial standard tcp.h header file. 16070 - libc: Add support for readv() and writev(). 16071 - libc: Adds tcflow(). 16072 - libc: Add support for sigwait(). 16073 - libnx: Changes to allow the font subsystem to be built without 16074 enabling the entire graphics system (CONFIG_NX). Adds 16075 CONFIG_NXFONTS and CONFIG_NXGLIB. Needed to duplicate some Kconfig 16076 setting for NXFONTs if it can be configured and built independently 16077 of NX. 16078 16079 * Tools: 16080 16081 - tools/configure.sh: Add special support so that you can start with a 16082 windows native configuration and install on a different host (and 16083 vice versa). 16084 - tools/configure.c: Duplicate new functionaity added to configure.sh. 16085 - tools/configure.sh: This commit adds a -m option for macOS. For 16086 anyone not aware, Apple renamed OSX to macOS recently; thus the 'm' 16087 instead of 'o'. This does not change the other uses of *_OSX to 16088 macOS. From jeditekunum. 16089 - tools/configure.c: Update functionality to match last change to 16090 tools/configure.sh. 16091 16092 * NSH: apps/nshlib: 16093 16094 - apps/nshlib: mount command no long uses the non-standard OS 16095 interface foreach_mountpoint(). Now simply cats /proc/fs/mount 16096 when there are no arguments to the mount command. 16097 - apps/nshlib: df command no long uses the non-standard OS interface 16098 foreach_mountpoint(). Now simply cats /proc/fs/blocks or 16099 /proc/fs/usage. 16100 - apps/nshlib: The free commands no longer used mallinfo() to get 16101 the state of the use heap. Two reasons: That is not useful 16102 information in the kernel build. And (2) there are other memory 16103 resources of interest in other configurations such as the Kernel 16104 heap in PROTECTED and KERNEL builds, and the prog mem uses when 16105 FLASH is used to hold modifiable data. The free command has been 16106 extended to just dump the content of procfs entries and to include 16107 all of these other memory resources of the procfs entries are 16108 available. 16109 16110 * Examples/Tests: apps/examples: 16111 16112 - apps/examples/fb: Add a simple test for the framebuffer character 16113 driver.. 16114 - apps/examples/ostest: sem_open() now returns SEM_FAILED in the 16115 event of a failure. 16116 - examples/ostest: Extend cancellation test to make sure that 16117 cancelable threads waiting on a message queue or on a signal can be 16118 canceled. 16119 - Added a simple reader example for the LIS3DSH acceleration sensor 16120 on STM32F4Discovery. From Florian Olbrich. 16121 - apps/examples/apa102: Add a Rainbow example for APA102 LED Strip. 16122 From Alan Carvalho de Assis. 16123 - apps/examples/flowc: Add a simple test of serial hardware flow 16124 control. 16125 - Add powerled driver example. From Mateusz Szafoni. 16126 - apps/examples/ina219: A simple infinite loop that polls the INA219 16127 sensor and displays the measurements. From Sebastien Lorquet. 16128 - apps/examples/alarm: Add options for reading alarm value and 16129 canceling it. From Juha Niskanen. 16130 - Add -n samples to lm75 app and replace Centigrade with Celsius. 16131 From Alan Carvalho de Assis. 16132 - apps/examples/adps9960: Add ADPS-9960 example. From Alan Carvalho 16133 de Assis. 16134 - apps/examples/obd2: Add OBD2 example application. From Alan 16135 Carvalho de Assis. 16136 - apps/examples/userfs: Add a test case for verifying UserFS. 16137 - apps/examples/smps: Add SMPS driver example. From Mateusz Szafoni. 16138 - apps/examples/pdcurses: Bring in pdcurses demos and make them 16139 conform to the NuttX coding style. 16140 - apps/examples/pdcurses: Add a very simple example that just shows 16141 the entire character set (7-bit only). It adapts to the size of 16142 the framebuffer and, hence, can be used with very tiny displays. 16143 In fact it looks really dumb on big displays. 16144 - apps/examples/nunchuck: Add Nunchuck example application. From 16145 Alan Carvalho de Assis. 16146 16147 * File System Utilities: apps/fsutils: 16148 16149 - apps/fsutils/mkfatfs: Move mkfatfs from the OS to here. 16150 16151 * Network Utilities: apps/netutils: 16152 16153 - apps/netutils/netlib: Add netlib_ipv6adaptor() and 16154 netlib_ipv4adaptor(). 16155 - apps/netutils/netlib: Add helpers for reading the routing table: 16156 netlib_read_ipv4route() and netlib_read_ipv6route(). 16157 - apps/netutils/netlib: Add new utilities netlib_ipv[4|6]router() 16158 that can be used to determine the IP address of a router that would 16159 be used some some destination IP address that is not locally 16160 accessible. 16161 - apps/netutils/ftpc: Adds support for IPv6 and fixes various 16162 transfer issues. From Anthony Merlino. 16163 16164 * CANUtilities: apps/canutils: 16165 16166 - apps/canutils/libobd2: Add libobd2 for NuttX. From Alan Carvalho 16167 de Assis. 16168 16169 * Graphics: apps/graphics: 16170 16171 - graphics/traveler: Convert to use the framebuffer driver. 16172 - apps/graphics/pdcurs34: This commit brings the public domain 16173 pdcurses library into NuttX. NuttX graphics support based on the 16174 framebuffer character drivers has been integrated. Input is 16175 currently limited to a discrete joystick driver. 16176 16177 * Wireless Utilities: apps/wireless: 16178 16179 - apps/wireless/ieee802154/i8sak: Adds socket interface support. You 16180 can now use both socket or char driver to control the MAC layer. 16181 From Anthony Merlino. 16182 - apps/wireless/ieee802154/i8sak: Adds sniffer port option and a few 16183 other get/set parameters. From Anthony Merlino. 16184 - apps/wireless/ieee802154/i8sak: Changes 'notif' to 'primitive' 16185 corresponding to the changes in the Kernel. From Anthony Merlino. 16186 - apps/wireless/ieee802154/i8sak: Channel setting is now saved 16187 locally, so when performing a startpan or assoc, the channel 16188 previously set is still used, even though the MAC layer gets reset. 16189 From Anthony Merlino. 16190 - apps/wireless/ieee802154/i8sak: Adds ability to get/set rxonidle 16191 setting for MAC layer. From Anthony Merlino. 16192 - apps/wireless/ieee802154/i8shark: Adds i8shark, a sniffer "adapter" 16193 that captures all 802.15.4 traffic, packages it into a Wireshark ZEP 16194 packet, and sends it to a host running Wireshark From Anthony 16195 Merlino. 16196 16197 * System Utilities (apps/system) 16198 16199 - apps/system/ping and ping6: This commit removes the ping and ping6 16200 commands from NSH and replaces then with the apps/system/ping and 16201 apps/system/ping6 built-in commands. The NSH ping[6] commands had 16202 to be removed because they violated the portable POSIX OS interface. 16203 The apps/system/png and ping6 command uses the sem-standard 16204 IPPROTO_ICMP and IPPROTO_ICMP6 socket interfaces. 16205 16206 * Platform-Specific Support (apps/platform) 16207 16208Bugfixes. Only the most critical bugfixes are listed here (see the 16209ChangeLog for the complete list of bugfixes and for additional, more 16210detailed bugfix information): 16211 16212 * Core OS: 16213 16214 - Task Environment Creation: Fix an error in the duplication of the 16215 child tasks environment in the special case where the parent's 16216 environment was created, but then all of the variables were unset. 16217 In that case, there is still an allocation in place but the size of 16218 the allocation is zero. This case was not being handled correctly 16219 when a child task attempts to create its environment and inherit the 16220 zero-size partent environment. Noted by Anthony Merlino. 16221 - timer_create(): Fix watchdog resource leak if cannot allocate a new 16222 timer. From Bruno Herrera. 16223 - OS Internal Functions: Internal OS functions should not return error 16224 information via the user errno variable: This includes functions 16225 like file_seek(), file_read(), file_write(), etc. The complete list 16226 is too long to duplicate here (please refer to the ChangeLog for 16227 details). 16228 - OS Internal Functions: Not only should internal OS functions not 16229 modify the errno variable, they should never introduce cancellation 16230 points: psock_connect(), psock_listen(), psock_getsockopt(), etc. 16231 The list is too long to duplicate here (please refer to the 16232 ChangeLog for details). 16233 - OS Internal Functions: Create OS internal versions of many 16234 applications functions that were used by the OS. The new versions 16235 differ from the application interfaces in that (1) they do not 16236 return error information via the errno variable, and (2) they never 16237 create cancellation points. This includes new internal interfaces 16238 like nxsem_init() that is like sem_init(), etc. There are too many 16239 to list here (see the ChangeLog for details). 16240 - Task Exit: task_exithook.c fails to link if signals are disabled 16241 because was unconditionally trying to send the SIGCHLD signal to the 16242 parent in certain configurations. Noted by Jeongchan Kim. 16243 - memalign(): Fix heap corruption caused by using unaligned chunk 16244 size. Unaligned nodes generated by memalign later cause heap 16245 corruptions when nodes are shrink further (for example, 24 bytes -> 16246 8 bytes, when alignment is 16 bytes). From Jussi Kivilinna. 16247 - SMP: In sched/sched/sched_cpuselect.c, in order to find the cpu 16248 with the lowest priority thread, we have to remember the already 16249 found lowest priority. Noted by Anonymous in Issue #75. 16250 - spinlocks: Disable local interrupts in spin_setbit() and 16251 spin_clrbit() in order to avoid a deadlock condition. From Masayuki 16252 Ishikawa. 16253 - atexit()/on_exit(): Clear atexit()/on_exit() function pointer 16254 before calling it. On most archs, up_assert() calls exit() so 16255 without this change, if atexit() function triggers an assertion we 16256 are in endless loop. From Juha Niskanen. 16257 16258 * File System/Block and MTD Drivers: 16259 16260 - tmpfs: Fixed directory unlocking in tmpfs_opendir. From Dmitriy 16261 Linikov. 16262 - fcntl(): fcntl() did not return success fail for F_SETFL. Reported 16263 by Jussi Kivilinna. 16264 - tcdrain(): tcdrain() was recently added to the NuttX C library. 16265 But there is a problem. The specification of tcdrain() requires 16266 that it be a cancellation point. In order to do this, tcdrain was 16267 moved from the C library into the OS and the addition cancellation 16268 point hooks were added. In non-FLAT builds, access via system calls 16269 is also now supported. 16270 - FS FAT: Fix hard-fault when listing contents of FAT root. From 16271 Jussi Kivilinna. 16272 - procfs: Correct a problem that was causing an apparent directory to 16273 be reported as a file instead of a directory by opendir. This 16274 happened after adding these three new procfs entries: fs/block, 16275 fs/mount, and fs/usage. Of course, there is no directory fs in this 16276 case, only three files that have fs/ in their relative pathnames. 16277 The logic was detecting that fs was the name of the enty to report, 16278 but it was then declaring that fs was a file (because fs/block is of 16279 type file). This was fixed by adding a check for matching lenghts. 16280 i.e., if strlen(fs) != strlen(fs/block), then report fs as a 16281 directory instead of a file. 16282 - procfs: Fix uptime being clse to maximum 32-bit value in certain 16283 config. From Juha Niskanen. 16284 16285 * Binary Loader: 16286 16287 - binfmt/: Don't schedule starthook if there are no constructors. 16288 16289 * Graphics/Display Drivers: 16290 16291 - LCD: ILI9341 initialize method not permitted to set errno. 16292 16293 * Networking/Network Drivers: 16294 16295 - Networking: net/netdev/netdev_ifconfig.c: Was not returning all of 16296 the address info. 16297 - Networking: In some cases, packets are still not sent behind the 16298 router. I found that NuttX sends the ARP requests not to the router 16299 but to the target. Mistake in file net/route/netdev_router.c. From 16300 Aleksandr Kazantsev. 16301 - SIOCGIFCONF and SIOCGLIFCONF IOCTL commands should only report on 16302 network adatpors in the UP state. 16303 - recvfrom(): Fix double leave_cancellation_point on error path. 16304 From Jussi Kivilinna. 16305 - send(): Verify that sock descriptor is valid. Fixes assertion when 16306 using send on closed socket. From Jussi Kivilinna. 16307 - sendto(): Remove assert check for null psock and buf input 16308 pointers. Removes check as 'psock == NULL' altogether because that 16309 checked for later in psock_send and psock_sendto. Change null check 16310 for 'buf' so that it is handled same as in recvfrom.c (return 16311 -EINVAL instead of assert). From Jussi Kivilinna. 16312 - sockgetname() files need to include udp/udp.h and tcp/tcp.h or 16313 otherwise NET_UDP_HAVE_STACK and NET_TCP_HAVE_STACK are undefined 16314 and the logic is never compiled. Noted by Anthony Merlino. 16315 - dup()/dup2(): There was a reference counting problem in the TPC 16316 logic of net_clone(). net_clone() which is the common logic 16317 underlying dup() and dup2() for sockets. When net_clone() calls 16318 net_start_monitor() and net_start_monitor() returns a failure 16319 (because the underlying TCP connection) then net_clone() must back 16320 out the reference count on the structure. Problem noted by Pascal 16321 Speck and this implementation of the solution is based on his 16322 suggestion. 16323 - close(): There was a possible recursion that could eventually 16324 overflow the stack. The error occurred when closing the socket with 16325 inet_close() while a socket callback was still queued. When the 16326 socket callback was executed by devif_conn_event(), this resulted in 16327 a call to psock_send_eventhandler() with TCP_CLOSE flag set which 16328 then called tcp_lost_connection(). tcp_shutdown_monitor() then 16329 called tcp_callback() again, which again called 16330 psock_send_eventhandler(), and so on.... Noted by Pascal Speck. 16331 Solution is also similar to a solution proposed by Pascal Speck. 16332 - inet: Add check for protocol before handing out TCP and UDP sockets. 16333 - IP Forwarding: Fixes typo that caused build error when IP 16334 forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as 16335 well. From Anthony Merlino. 16336 - IP Forwarding: Do not add link layer header size to d_len inside 16337 devif_forward(). From Anthony Merlino. 16338 - TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a 16339 situation where a NULL pointer may be dereferenced. In this 16340 configuration, the TCP connection's 'semi-permanent' callback, 16341 s_sndcb was nullified in tcp_close_disconnect. However, other logic 16342 in tcp_lost_connection() attempt to use that callback reference 16343 after it was nullifed. Fixed in tcp_lost_connectino() by adding a 16344 NULL pointer change before the access. This was reported by Dmitriy 16345 Linikov in Bitbucket Issue 72. 16346 - UDP Broadcat: Fix some issues with regard to UDP broadcast 16347 handling. This is Bitbucket Issue #77. 16348 - ICMP: Fix an error in the poll logic. It was assumed that the 16349 input parmeter pvconn was valid. It was not. Instead, the poll 16350 logic must work like the sendto() and recvfrom() logic: It must 16351 keep a copy of the conn structure in the private data. 16352 - ICMPv6: Fixes several errors preventing icmpv6_radvertise.c from 16353 being compiled. Fixes conversions to network byte order (namely 16354 vlifetime, plifetime, mtu). IPv6 source address is set to 16355 link-local IP address instead of the address in the netdev 16356 structure. This is in compliance to RFC 4861. RA didn't work on 16357 Linux before this change. Finally, router prefix and prefix length 16358 are derived from the IPv6 address and netmask in the netdev 16359 structure. This seems to make more sense than using a predefined, 16360 separate prefix from the config. From Sakari Kapanen. 16361 - ICMPV6: icmpv6_input() needs to set d_len to 0 after consuming echo 16362 reply, otherwise, garbage will get sent out. From Anthony Merlino. 16363 - ICMPV6: Fix an error in the poll logic. It was assumed that the 16364 input parmeter pvconn was valid. It was not. Instead, the poll 16365 logic must work like the sendto() and recvfrom() logic: It must 16366 keep a copy of the conn structure in the private data. 16367 - IGMPv2 Send: Fix incoming IGMP checksum calculation. From Louis 16368 Mayencourt. 16369 - ARP: Fix IGMP Ethernet address computation. From Louis Mayencourt. 16370 16371 * Wireless/Wireless Drivers: 16372 16373 - CC1101: CC1101 driver not permitted to set errno. 16374 - 6LoWPAN: Correct an error in uncompressing multicast address. 16375 - 6LoWPAN: Correct a bug in handling uncompressed frames (IPv6 16376 dispatch). Adds a separate local variable, protosize, to keep track 16377 of the size of thep protocol header. 16378 - 6LoWPAN: Fix an endian-ness problem in 6LoWPAN address 16379 decompression. From Anthony Merlino. 16380 - 6LoWPAN: The logic that extracts interface identifier from the IP 16381 address needs to be generalized to handle cases where the address is 16382 not a link local address. From Anthony Merlino. 16383 16384 * Common Drivers: 16385 16386 - Serial: 16550 UART driver IOCTL method must not set errno; it must 16387 return a negated errno value. 16388 - LIS3DSH: Added the argument parameter (FAR void *arg) to the 16389 interrupt handler provided by the LIS3DSH driver to fit the 16390 definition for ISRs in xcpt_t. Changed the check for working queue 16391 availability in lis3dsh interrupt handler to use work_available() 16392 and not crash in case of an overrun. From Florian Olbrich. 16393 - LIS2DH: Fixes for self-test. From Jussi Kivilinna. 16394 - LIS2DH: Fix use of obsolete dbg macro. From Jussi Kivilinna. 16395 - LIS331DL: LIS331DL driver not permitted to set errno. 16396 - HTS221: Power-on sensor for loading calibration data. From Jussi 16397 Kivilinna. 16398 - MCP2515: Fix the MCP2515 Bit Rate Prescale calculation. Fix BRP 16399 for SET_BITTIMING ioctl as well. From Alan Carvalho de Assis. 16400 - STMPE811: Fix GPIO operation of STMPE811 driver. 16401 1. STMPE811_GPIO_DIR was defined for register name and later was 16402 redefined to be the pin direction mask for `stmpe811_gpioconfig`. 16403 I decided to change register name to be STMPE811_GPIO_DIR_REG, and 16404 keep pin direction mask STMPE811_GPIO_DIR, so that any external 16405 code that already use this driver will be unchanged. 16406 2. The STMPE811 register GPIO_DIR uses bit value 1 for output and 0 16407 for input, but `stmpe811_gpioconfig` set the opposite. 16408 3. The call to `stmpe811_gpiowrite` from inside of 16409 `stmpe811_gpioconfig` leaded to deadlock. 16410 From Dmitriy Linikov. 16411 - BQ2429X: Add BATIO_OPRTN_SYSON for enabling BATFET after SYSOFF. 16412 From Jussi Kivilinna. 16413 16414 * Simulation: 16415 16416 - Simulation: Serial and console drivers are not permitted to set 16417 the errno. 16418 16419 * ARMv7-M: 16420 16421 - ARM Stack Check: Fix assert panic when both TLS and interrupt stack 16422 are enable. From Jussi Kivilinna. 16423 16424 * Infineon XMC4xxx Drivers: 16425 16426 - XMC4 USIC: Kconfig was not selecting XMC4_USIC for USIC1. From Alan 16427 Carvalho de Assis. 16428 - XMC4 UART: Fix XMC4xxx USIC UART sginal to be high level when in idle. 16429 From Alan Carvalho de Assis. 16430 - XMC4 UART:xmc4_uart_configure() expects the channel# not uartbase as 16431 an input parameter. From Alan Carvalho de Assis. 16432 - XMC4 UART: Enable RX/TX status. From Alan Carvalho de Assis. 16433 - XMC4 UART: The Alternative Receive Interrupt was not being 16434 configured. 16435 16436 * Infineon XMC4xxx Boards: 16437 16438 - XMC4500-Relax: Setup max. freq. 120MHz and setup pull-up to UART 16439 RXD pin. From Alan Carvalho de Assis. 16440 16441 * Microchip/Atmel SAMv7 Drivers: 16442 16443 - SAMv7: DAC and ADC drivers are not permitted to set the errno. 16444 - SAMv7: Correct an error in RX DMA setup. From Manish Kumar Sharma. 16445 - SAMv7 USB: It is necessary to disable pre-emption and interrupts 16446 around a loop that copies TX data into the hardware in order to 16447 avoid a TX data underrun condition. From Anthony Merlino. 16448 16449 * NXP/Freescale LPC31xx Drivers: 16450 16451 - LPC31xx: Serial and console drivers are not permitted to set 16452 the errno. 16453 16454 * NXP/Freescale LPC43xx: 16455 16456 - lpc43xx: lpc43_adc.c was being selected by the build system wehn 16457 DAC was selected. 16458 16459 * NXP/Freescale LPC43xx Drivers: 16460 16461 - LPC43xx Ethernet: Fix some backward logic setting full-duplex and 16462 100mbps when autoconfiguration is disabled. Noted by Anonymous in 16463 Issue #76. 16464 - lpc43xx: UART_RX pins should be configured with input buffers 16465 enabled. Otherwise it cannot be read. From Alexander Vasiljev. 16466 16467 * STMicro STM32: 16468 16469 - STM32 F2: Fixed build for STM32F20XX platforms when 16470 CONFIG_STM32_DMACAPABLE is enabled. From Dmitriy Linikov. 16471 - STM32 F4: Remove ltdc.h and dma2d.h. Those header files in that 16472 location permitted inclusion into application space logic and, 16473 hence, facilitated and encouraged calling into the OS and violating 16474 the portable POSIX OS interface. The definitions in those header 16475 files were move the appropriate location in the counterpart, 16476 architecture specific files at arch/arm/src/stm32/dma2d.h and ltdc.h. 16477 - STM32 L4: Build stm32l4_idle.c only if CONFIG_ARCH_IDLE_CUSTOM is 16478 not enabled. From Jussi Kivilinna. 16479 - STM32 F7: Remove ltdc.h and dma2d.h. Those header files in that 16480 location permitted inclusion into application space logic and, 16481 hence, facilitated and encouraged calling into the OS and violating 16482 the portable POSIX OS interface. The definitions in those header 16483 files were move the appropriate location in the counterpart, 16484 architecture specific files at arch/arm/src/stm32f7/dma2d.h and 16485 ltdc.h. 16486 16487 * STMicro STM32 Drivers: 16488 16489 - STM32: DAC and ADC drivers are not permitted to set the errno. 16490 - STM32 ADC: Clear pending interrupts. From Mateusz Szafoni. 16491 - STM32 CAN: Lower part of STM32 CAN driver 16492 arch/arm/src/stm32/stm32_can.c uses all three hw tx mailboxes and 16493 clears TXFP bit in the CAN_MCR register (it means transmission order 16494 is defined by identifier and mailbox number). 16495 This creates situation when order frames are put in upper part of 16496 CAN driver (via can_write) and order frames are sent on bus can be 16497 different (and I experience this in wild). Since CAN driver API 16498 pretends to be "file like" I expect data to be read from fd the same 16499 order it is written. So I consider described behaviour to be a bug. 16500 Fixed by settin the TXFP bit in the CAN_MCR register (FIFO 16501 transmit order). From comments by Alexey T, in Bitbucket Issue 73. 16502 - STM32 HRTIM: Fix pclk calculation. From Mateusz Szafoni. 16503 - STM32 HRTIM: Fix burst mode prescaler update. From Mateusz Szafoni. 16504 - STM32 (alt) I2C: Ensure proper error handling. Injecting data 16505 errors would cause the driver to continually reenter the isr with 16506 BERR an RxNE. This fix allows the error to be cleared and 16507 propagated to the waiting task. From David Sidrane. 16508 - STM32: LTDC and DMA2D drivers are not permitted to set the errno. 16509 - STM32 RTC: Workaround for potential subseconds race condition. In 16510 all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed 16511 to lock the values in the higher-order calendar shadow registers 16512 until RTC_DR is read. However many old chips have in their errata 16513 this silicon bug (at least F401xB/C, F42xx, F43xx, L15xxE, L15xVD 16514 and likely others): "When reading the calendar registers with 16515 BYPSHAD=0, the RTC_TR and RTC_DR registers may not be locked after 16516 reading the RTC_SSR register. This happens if the read operation is 16517 initiated one APB clock period before the shadow registers are 16518 updated. This can result in a non-consistency of the three 16519 registers. Similarly, RTC_DR register can be updated after reading 16520 the RTC_TR register instead of being locked." 16521 - STM32 Serial: Do not stop processing input in SW flow-control 16522 mode. From Juha Niskanen. 16523 - STM32F33xxx ADC: Add some publicly visable interfaces and some 16524 code to support injected channels. From Mateusz Szafoni. 16525 - STM32F33xxx DMA: Add public interface to handle with DMA 16526 interrupts. From Mateusz Szafoni. 16527 - STM32F33xxx RCC: Fix CAN clock enable. From Mateusz Szafoni. 16528 - stm32 F4 I2C: Ensure proper interrupt handling. Injecting data 16529 errors that causes a STOP to be perceived by the driver, will 16530 continually re-enter the isr with SB not set and BTF and RxNE set. 16531 This changes allows the interrupts to be cleared and propagates a 16532 I2C_SR1_TIMEOUT to the waiting task. From David Sidrane. 16533 - STM32 L4 Serial: Do not stop processing input in SW flow-control 16534 mode. From Juha Niskanen. 16535 - STM32 F7: LTDC and DMA2D drivers are not permitted to set the errno. 16536 - STM32 L4: DAC and ADC drivers are not permitted to set the errno. 16537 - STM32 L4 DAC: Do not configure output pin if it is not used. From 16538 Juha Niskanen. 16539 - STM32 L4 RTC, PM: Small fixes to subseconds handling, ADC 16540 power-management hooks 16541 - STM32 F4 RTC: Fix reading alarm value that is more than 24h in 16542 future. From Juha Niskanen 16543 - STM32 L4 RTC: Fix reading alarm value that is more than 24h in 16544 future. From Juha Niskanen 16545 - STM32 L4 TIM: Fix compilation of timers with complementary outputs 16546 when not PWM_MULTICHAN. From Juha Niskanen. 16547 - STM32 L4 RCC: Restore backup-registers after backup-domain reset. 16548 From Jussi Kivilinna. 16549 - STM32 L4 RTC: Correct RTC_SSR and RTC_TR read ordering. In all 16550 recent STM32 chips reading either RTC_SSR or RTC_TR is supposed to 16551 lock the values in the higher-order calendar shadow registers until 16552 RTC_DR is read. Change the register read ordering to match this and 16553 don't keep a workaround for a hypothetical race condition (not in 16554 any L4 errata, lets for once assume ST's silicon works as it is 16555 documented...) 16556 - STM32 L4 RTC: Init mode was never exited because nested locking in 16557 rtc_synchwait() disabled backup domain access. From Juha Niskanen. 16558 - STM32 L4 RTC: Use backup register magic value instead of INITS 16559 bit. The INITS (bit 4) of RTC_ISR register cannot be used to 16560 reliably detect backup domain reset. This is because we can operate 16561 our device without ever initializing the year field in the RTC 16562 calendar if our application does not care about correct date being 16563 set. Hardware also clears the bit when RTC date is set back to year 16564 2000. From Juha Niskanen. 16565 - STM32 L4 RTC: Put back the SSR race condition workaround. ST has 16566 confirmed that the issue has not been fixed, and that it applies to 16567 STM32 L4 too (was not in errata sheets due to documentation bug) See 16568 discussion: https://community.st.com/thread/43710-issue-with-rtc-maximum-time-resolution . 16569 From Juha Niskanen. 16570 - STM32 F7 BBSRAM: Avoid assert in stm32_bbsram_savepanic. If panic 16571 happens before stm32_bbsram is initialized, stm32_bbsram_savepanic 16572 caused additional assert panic. Function has null pointer check, so 16573 drop DEBUGASSERT. From Jussi Kivilinna. 16574 - STM32 F7 I2C: fix I2C_M_NORESTART handling. From Jussi Kivilinna. 16575 - STM32 F7 I2C: Restore bus frequency after I2C reset. Copy 16576 frequency restoration fix from STM32L4 I2C driver to STM32F7 I2C 16577 driver. From Jussi Kivilinna. 16578 - STM32 F7 RTC: Fix reading alarm value that is more than 24h in 16579 future. From Juha Niskanen 16580 16581 * STMicro STM32 Boards: 16582 16583 - STM32F334-DISCO: Add missing ram_vectors configuration in linker 16584 script. From Mateusz Szafoni. 16585 - Nucleo-F334R8: Add missing ram_vectors configuration in linker 16586 script. From Mateusz Szafoni. 16587 - Nucleo-F334R8: Add Missing ADC trigger configuration tot he highpri 16588 configuration. From Mateusz Szafoni. 16589 - STM3240G-EVAL: The timer frequencies (BOARD_TIMx_FREQUENCY) are 16590 incorrectly defined in�board.h. Since the APB prescalers are set to 16591 divide by 4 and 2 respectively, the frequencies should be "2xAPBx" 16592 as said in the comment.� The correct frequencies are already defined 16593 but as STM32_APBx_TIMx_CLKIN. From Mattias Edlund. 16594 - STM32F429i-DISCO: The ltdc configuration has been deleted because 16595 it violated the portable POSIX OS interface. It used 16596 apps/examples/ltdc and include ltdc.h and dma2d.h which were also 16597 removed for the same reason. 16598 16599 * ZiLOG Z80 16600 16601 - configs/z80sim and xtrs: Serial driver lower halfs ioctl methods 16602 should return a negated errno value, not set the errno variable. 16603 - z80 Make.defs: Fixes dependency generation with newest SDCC 16604 compiler. 16605 - configs/z80sim: Fix a naming problem. Also, don't try to build the 16606 serial driver if CONFIG_NFILE_DESCRIPTOR=0. 16607 - Z80: Makefile fix for use with current SDCC. 16608 16609 * Build System 16610 16611 - configs/: All defconfig filess that include 16612 CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and 16613 deselect CONFIG_DISABLE_POLL. 16614 - configs/: All NX configuration... Because of recent changes to 16615 libnx/nxfonts, Supported bit per pixel must be separated specified 16616 for NXFONTs too and need to match the select BPP for NX. 16617 - Build system: Fix CONFIG_BUILD_KERNEL logic directories that have 16618 ubin and kbin subdirectories. Conditional logic was fine for 16619 CONFIG_BUILD_FLAT and CONFIG_BUILD_PROTECTED but generated useless 16620 dependencies if CONFIG_BUILD_KERNEL. 16621 16622 * C Library/Header Files: 16623 16624 - libc/stdio: Build the lib_noflush() and lib_snoflush() stubs even 16625 if CONFIG_FILE_DESCRIPTORS=0. They may still be needed. 16626 - libc and libnx: When the libraries are built into two libraries, a 16627 user space library and a OS space library (as in the PROTECTED and 16628 KERNEL build). Then the user space library must not use the OS 16629 internal interfaces; similarly, the OS must avoid using the 16630 userspace interfaces so that it does not muck the errno value or 16631 create spurious cancellation points. 16632 - libc/match: Use of exp() vs expf() in logf() caused function to be 16633 slow. From Alan Carvalho de Assis. 16634 - libnx: Fixes a memory leak that is caused because the client message 16635 queue is not unlinked after the client disconnects from the NX 16636 server. From Masayuki Ishikawa. 16637 - sscanf(): Fix sscanf() character conversion (%c): do not add '\0' at 16638 the end as for strings, cause, for example, parsing one character 16639 will fill two bytes: character itself and zero one '\0' after it, so 16640 will overflow one byte variable argument and corrupt memory for 16641 variables allocated after it. From Oleg Evseev. 16642 16643 * Tools 16644 16645 - tools/: configure.sh and configure.c should redirect stdout to 16646 /dev/null but should not suppress stderr output. 16647 16648 * NSH: apps/nshlib: 16649 16650 - apps/nshlib/: Avoid truncating the strcmp result in the parser 16651 into a unsigned char variable. nshlib/nsh_netcmds.c: Check for 16652 valid hostip before using it. From Bruno Herrera. 16653 - apps/nshlib/: Fix resouce leak in 'dd' commenad when 'if=' or 16654 'of=' params are repeated in the command line. For example: 16655 dd if=/dev/null if=/dev/zero of=/dev/null or 16656 dd if=/dev/zero of=/dev/zero of=/dev/null. From Bruno Herrera. 16657 - apps/nshlib: This commit eliminates the ping and ping6 commands 16658 from NSH and replaces them with 'built-in' commands at 16659 apps/system/ping and ping6. The original NSH version of ping[6] 16660 commands violated the portable POSIX interface and, hence, had to 16661 be removed. The new system/ping and ping6 built-in commands uses 16662 the new IPPROTO_ICMP AF_INET and IPPROTO_ICMP6 AF_INET6 datagram 16663 sockets to implement ping. 16664 - apps/nshlib: Fix parsing of empty strings when CONFIG_NSH_CMDPARMS 16665 is not defined. Problem noted by Juha Niskanen. 16666 16667 * Examples/Tests: apps/examples: 16668 16669 - All configurations that use NXIMAGE or NXHELLO must select 16670 NX_MULTIUSER. All configurations that use examples/nxterm must 16671 enable CONFIG_LIB_BOARDCTL. 16672 - All configurations that use NXLINES must select NX_MULTIUSER. All 16673 configurations that use the NX server need to have larger POSIX 16674 messages. 16675 - apps/examples/adc: Fix g_adcstate.count initialization. From 16676 Masayuki Ishikawa. 16677 - apps/examples/elf: Remove low-level interfaces and replace with 16678 call to exec(). 16679 - apps/examples/nxflat: Remove low-level interfaces and replace with 16680 call to exec(). 16681 - examples/ostest: Works around a bug in printf() when cancellation 16682 points are enabled. printf() is a cancellation point because it 16683 calls write(). This is correct according to OpenGroup.org. 16684 However, printf holds the stdio library semaphore when it is 16685 canceled and this leaves the semaphore in a bad state. No fix for 16686 the printf bug yet. 16687 - apps/examples/nx: The NX example no longer supports single user 16688 mode. 16689 - apps/examples/nxtext: The nxtext example no longer supports single 16690 user mode. 16691 - apps/examples/nxhello now supports only multiuser mode. 16692 - apps/examples/nximage now supports only multiuser mode. 16693 - examples/nxlines: Now supports only multiuser mode. 16694 16695 * Network Utilities: apps/netutils: 16696 16697 - apps/netutils/ftpc: Fix some crazy comparisons to determine is a 16698 file is an absolute path. Noted by Anthony Merlino. 16699 16700 * System Utilities (apps/system) 16701 16702 - apps/system/i2ctool: Fixed i2ctool write operation in `no restart` 16703 mode (flag `-n`). It seems that I2C driver has changed a bit since 16704 i2ctool was written, so now i2ctool sends repeated start even if 16705 `no restart` flag (-n) was passed to it. From Dmitriy Linikov. 16706 16707NuttX-7.24 Release Notes 16708------------------------ 16709 16710The 124th release of NuttX, Version 7.24, was made on March 2, 2018, 16711and is available for download from the Bitbucket.org website. Note 16712that release consists of two tarballs: nuttx-7.24.tar.gz and 16713apps-7.24.tar.gz. These are available from: 16714 16715 https://bitbucket.org/nuttx/nuttx/downloads 16716 https://bitbucket.org/nuttx/apps/downloads 16717 16718Both may be needed (see the top-level nuttx/README.txt file for build 16719information). 16720 16721Additional new features and extended functionality: 16722 16723 * Core OS: 16724 16725 - SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore(). 16726 These APIs are simplified version of enter_critical_section() 16727 and leave_critical_section() to protect data (e.g. registers) in 16728 SMP mode. By using these APIs inside drivers, performance will 16729 be improved. From Masayuki Ishikawa. 16730 - System Timer: Replace critical section APIs with spinlock APIs. 16731 (64bit only). If SMP=n or SMP=y && SPINLOCK_IRQ=n, this works 16732 in the same way as before. If SMP=y && SPINLOCK_IRQ=y, performance 16733 will be improved. From Masayuki Ishikawa. 16734 - POSIX Timers: Replace critical section APIs with spin lock APIs in 16735 clock_gettime.c. This change will improve performance for SMP 16736 systems but nothing changes for non-SMP systems. In SMP mode, 16737 the running TCB is not always at the g_readytorun.head. From 16738 Masayuki Ishikawa. 16739 - SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note(). These 16740 APIs are used in sched_note.c to protect instrumentation data. The 16741 difference between these APIs to exsiting spin_lock() and 16742 spin_unlock() is that they do not perform instrumentation to avoid 16743 recursive call when SCHED_INSTRUMENTATION_SPINLOCKS=y. From 16744 Masayuki Ishikawa. 16745 - Interrupts: Add a configuration option to show interrupt 16746 information via a procfs file. 16747 16748 * File Systems/Block and MTD Drivers 16749 16750 - VFS: Add support for truncate() and ftruncate(). 16751 - FAT, SmartFS, UserFS, UnionFS, TmpFS, NFS: Add truncate() support. 16752 - FAT. Effectively handles the situation when a new file position is 16753 within the current sector. Accelerates the work of the FS with a 16754 multitude of operations to write small pieces of data within the 16755 current sector. From Aleksandr Vyhovanec. 16756 16757 * Graphics/Display Drivers: 16758 16759 - HiletGo OLED: Add configuration support for HiletGo SSD1306 OLED. 16760 - lcd/ft80x: This commit adds an FTDI/BridgeTek FT80x GUI driver. It 16761 is untested (I don't even have hardware yet) and, hence, it is 16762 marked as EXPERIMENTAL). 16763 16764 * Networking/Network Drivers: 16765 16766 - 6LoWPAN: Adds configuration options for specifying preloaded 16767 address contexts for compression From Anthony Merlino. 16768 - TCP: Introduce tcp receive window control based on I/O buffer. 16769 NOTE: The algorithm is still experimental but useful for http 16770 streaming. From Masayuki Ishikawa. 16771 - UDP: Add an implementation of UDP write buffering. 16772 - Routing Tables: Adding ftruncate() support eliminates an issue 16773 in file-based routing table management system. 16774 - Telnet: Add support for Telnet character mode From Masayuki 16775 Ishikawa. 16776 16777 * Other Common Device Drivers: 16778 16779 - drivers/input/ft5x06.c: Add a driver for the FT5x06 capacitive, 16780 multi-touch, touchscreen controller. 16781 - drivers/input/ft5x06: Add a polled mode of operation for the FT5x06 16782 in attempt to work around the fact that the LPCXpresso-LPC54628 16783 chose a non-interrupt pin for the FT5x06 interrupt. Driver is still 16784 not yet functional. 16785 - drivers/power/bq2429x.c: Add trickle charging mode From Juha 16786 Niskanen. 16787 - drivers/sensors: Add support to MAX44009 ambient light sensor. 16788 From Juha Niskanen. 16789 - drivers/sensors: Added support for LIS3DH accelerometer sensor. 16790 From Matt Thompson. 16791 - drivers/eeprom: EEPROM driver for AT24xx compatible EEPROMs. 16792 From Sebastien Lorquet. 16793 16794 * Simulation 16795 16796 - sim: Add support for a RAM MTD driver and initialization for use 16797 with SmartFS. 16798 - sim: Add support for testing NXFFS. 16799 16800 * ARM: 16801 16802 - ARMv7-A, ARMv7-R, ARMv7-M: Add atomic read-add-write and 16803 read-subtract-write functions. 16804 16805 * Infineon XMC4xxx: 16806 16807 - XMC4xxx: Refactor PLL setup, refactored PLL/CLK config, easier, 16808 checks for correctness, call go_os_start if STACK_COLORIZED, smarter 16809 config of EXTCLK output freq. From David Alessio. 16810 16811 * Infineon XMC4xxx Boards: 16812 16813 - Add FPU to xmc4 ostest. Remove +x from makefiles, preserve 16814 .gdbinit across make clean, add FPU support to ostest on xmc4, 16815 add FPU test to ostest on xmc4 From David Alessio. 16816 16817 * Microchip/Atmel SAMD/L Drivers: 16818 16819 - SAMD: SAMD External Interrupt Controller (EIC) support From Matt 16820 Thompson. 16821 - SAMD/L: Added Analog Comparator basic initialization From Matt 16822 Thompson. 16823 - SAMD/L: Added FDPLL clock support. Fixed sequence of OSC32K 16824 calibration setup. From Matt Thompson. 16825 - SAMD/L: Added loading factory USB calibration data from NVRAM. 16826 From Matt Thompson. 16827 - SAMD/L: Added experimental DMA support to SPI driver. spi_exchange() 16828 uses a pair of DMA channels for TX and RX. From Matt Thompson. 16829 16830 * Microchip/Atmel SAM3/4 Boards: 16831 16832 - Flip&Click SAM3X: Add board support for the Mikroe Flip&Click 16833 SAM3X. 16834 - Flip&Click SAM3X: Adds basic board support for the HiletGo OLED. 16835 16836 * Microchip PIC32MZ 16837 16838 - PIC32MZEF: Add architectural support for the PIC32MZEF family. 16839 16840 * Microchip PIC32MZ Boards 16841 16842 - Flip&Click PIC32MZ: Adds board support for the Mikroe Flip&Click 16843 PIC32MZ board. 16844 - Flip&Click PIC32MZ: Add board support for HiletGo OLED. 16845 - Flip&Click PIC32MZ: Add an nxlines configuration for use in 16846 testing the custom HiletGo Click board. 16847 16848 * NXP Freescale LPC43xx Drivers: 16849 16850 - LPC43xx: Adapt LPC176x RTC driver for the LPC43xx.

From Alan Carvalho 17040 de Assis. 17041 - apps/graphics/ft80x: Add the FTDU FT80x GUI support library. 17042 Consists of some display list helpers, audio helpers, touch helpers, 17043 RAM access, register access etc. 17044 17045 * System Utilities (apps/system) 17046 17047 - apps/system/nxplayer: Add support for HTTP streaming in nxplayer. 17048 From Masayuki Ishikawa. 17049 - apps/system/setlogmask: Adds 'setlogmask' application that allows 17050 you to set the syslog priority via a simple command. From Anthony 17051 Merlino. 17052 - apps/system/usbmsc: Added Kconfig options to configure write 17053 protection for each LUN. From Fabio D'Urso. 17054 - system/stackmonitor: Re-design the stack monitor so that it does not 17055 make forbidden calls directly into the OS, breaking the portable POSIX 17056 OS interface. It now properly uses the PROCFS file system to glean 17057 information about stack usage. 17058 17059Bugfixes. Only the most critical bugfixes are listed here (see the 17060ChangeLog for the complete list of bugfixes and for additional, more 17061detailed bugfix information): 17062 17063 * Core OS: 17064 17065 - System Timer: Change the way that the 64-bit time is sampled. 17066 Previously, we disabled interrupts before sampling the 64-bit 17067 timer since the uint64_t access is not atomic on most CPUs. However, 17068 disabling (local) interrupts does not work in the SMP case. In that 17069 case, the timer interrupt may be running on only one of the CPUs; 17070 disabling interrupts on a different CPU will provide no protection 17071 from timer rollover. To work around this, logic was added that 17072 samples 64-bit timer is sampled twice and if 32-bit rollover was 17073 detected between samples, then loops until there is no rollover. 17074 - POSIX Timers: In SMP mode, running TCB is not always at the head of 17075 the g_readytorun list. This change removes DEBUGASSERT() to avoid 17076 this condition. From Masayuki Ishikawa. 17077 - Spinlocks: Add memory barrier operations in spin_unlock(). In ARM 17078 document regarding memory barriers, SP_DMB() must be issued before 17079 changing a spinlock state to SP_UNLOCKED. However, we found that 17080 SP_DSB() is also needed to ensure that spin_unlock() works 17081 correctly for network streaming aging test. From Masayuki Ishikawa. 17082 - Sporadic Scheduler: Fix compiler error in Sporadic Scheduler when 17083 priority inheritance is enabled. Noted by eunb.song@samsung.com 17084 - Priority Inheritance: Fix some priority inheritance related issues 17085 noted during review of logic. Also add some REVISIT comments for some issues noted in the design. 17086 - boardctl: Remove the BOARDIOC_TSCTEST_TEARDOWN and 17087 BOARDIOC_TSCTEST_SETUP boardctl() commands. Remove all 17088 implementations of board_tsc_teardown(). Each board now initializes 17089 the touchscreen controller as a normal part of its board bring-up. 17090 board_tsc_setup() is gone; the touchscreen controller is now treated 17091 like any other on-board device. 17092 - configs: CONFIG_MAX_TASKS must be a power of 2. 17093 - SMP: Introduce a new global IRQ clearing logic and tasklist 17094 protection. The previous implementation of clearing global IRQ in 17095 sched_addreadytorun() and sched_removereadytorun() was done too 17096 early. As a result, nxsem_post() would have a chance to enter the 17097 critical section even nxsem_wait() is still not in blocked state. 17098 This patch moves clearing global IRQ controls from 17099 sched_addreadytorun() and sched_removereadytorun() to 17100 sched_resumescheduler() to ensure that nxsem_post() can enter the 17101 critical section correctly. For this change, 17102 sched_resumescheduler.c is always necessary for SMP configuration. 17103 In addition, by this change, task_exit() had to be modified so that 17104 it calls sched_resumescheduler() because it calls 17105 sched_removescheduler() inside the function, otherwise it will cause 17106 a deadlock. However, I encountered another DEBUGASSERT() in 17107 sched_cpu_select() during HTTP streaming aging test on LC823450-XGEVK. 17108 Actually sched_cpu_select() accesses the g_assignedtasks which might 17109 be changed by another CPU. Similarly, other tasklists might be 17110 modified simultaneously if both CPUs are executing scheduling logic. 17111 To avoid this, I introduced tasklist protection APIs. With these 17112 changes, SMP kernel stability has been much improved. From Masayuki 17113 Ishikawa. 17114 - SMP: Fix this_task() to be an atomic operation. In the previous 17115 implementation, this_task() was defined in sched.h by using just a 17116 macro current_task(this_cpu()). However, I found that this is not 17117 atomic and actually sometimes switching CPU happened in executing 17118 the macro when we tested audio steaming plus executing commands via 17119 Telnet. This change resolves this issue by implementing atomic 17120 this_task()in sched_thistask.c which is newly introduced. From 17121 Masayuki Ishikawa. 17122 - SMP: Implements a global scheduler lock capability as part of SMP 17123 support. This allows the scheduler to be locked with no knowledge 17124 or access to the TCB of the currently running task. This is 17125 necessary because accessing the TCB of the currently running task 17126 is, itself, a non-atomic operation. This global scheduler lock 17127 capability was add just to support that atomic access to the TCB. 17128 - SMP: Extend the last global lock change to work with the 17129 LC823450-XGEVK which does not support the atomic fetch add but 17130 does support disabling interprocessor interrupts. Disabling 17131 interprocessor interrupts will also guarantee that the TCB address 17132 calculation is atomic. 17133 - SMP: Fix a infinite recursion problems that a recent changes 17134 introduced into the i.MX6 SMP implementation. This is not seen 17135 with the LC823450 because you can disable inter-processor interrupts 17136 in that architecture; but you cannot in the ARMv7-A/GIC architecture. 17137 - SMP: Remove SMP related logic in sig_dispatch.c. This change 17138 prevents from a deadlock in up_schedulesigaction.c where inter-CPU 17139 signal handling is actually implemented. arch/arm/src/armv7-m: Fix 17140 signal handling for SMP. In previous implementation, signal handling 17141 for SMP was incorrect. Thus, for example, if an inter-CPU signal 17142 happened an incorrect tcb was signaled and caused ASSERT(). This 17143 change fixes the issues and works for both inter-CPU signal handling 17144 and signal handling on the same CPU. From Masayuki Ishikawa. 17145 - Tasking: Add nxtask_create(). Kthread_create() and nxtask_create() 17146 are internal OS functions and should not modify the errno variable. 17147 Convert legitimate uses of task_create() to nxtask_create(). 17148 Review handling of returned values from all uses of kthread_create() 17149 (as well as nxtask_create()). 17150 - Tasking: Threads started by board bring-up logic should be kernel 17151 threads, not user tasks. 17152 - Tasking: Threads started by drivers should be kernel threads, not 17153 user tasks. 17154 - Semaphore Usage: Added ECANCELED condition to DEBUGASSERT's 17155 checking sem_wait result From Dmitriy Linikov. 17156 17157 - errno: Add new internal OS function nxsched_setaffinity() that is 17158 identical to sched_isetaffinity() except that it does not modify the 17159 errno value. All usage of sched_setaffinity() within the OS is 17160 replaced with nxsched_setaffinity(). 17161 - errno: Internal functions sched_reprioritize() and 17162 sched_setpriority() no longer modify the errno value. Also renamed 17163 to nxsched_reprioritize() and sched_setpriority(). 17164 - errno: Add new internal OS function nxsched_getscheduler() that is 17165 identical to sched_getscheduler() except that it does not modify the 17166 errno value. All usage of sched_getscheduler() within the OS is 17167 replaced with nxsched_getscheduler(). 17168 - errno: Add new internal OS function nxsched_setparam() that is 17169 identical to sched_setparam() except that it does not modify the 17170 errno value. All usage of sched_setparam() within the OS is 17171 replaced with nxsched_setparam(). 17172 - errno: Add new internal OS function nxsched_getparam() that is 17173 identical to sched_getparam() except that it does not modify the 17174 errno value (actually, the previous value erroneously neglected to 17175 set the errno value to begin with, but this fixes both issues). All 17176 usage of sched_getparam() within the OS is replaced with 17177 nxsched_getparam(). 17178 - errno: wd_start() is an internal OS function and should not set the 17179 errno value. Reviewed and updated every call to wd_start() to 17180 verify if return value is used and if so if the errno value is 17181 accessed. 17182 - errno: Fix several inappropriate accesses to get_errno() that were 17183 missed in previous changes (some going back to nuttx-7.23). Add new 17184 nxsched_setscheduler() and nxsched_getaffinity() which are 17185 equivalent to their counterparts without the nx on front. These 17186 versions do not modify the errno value. Changed all calls within 17187 the OS to use these newer versions of the functions. 17188 - errno: binfmt/, configs/, grahics/, libc/, mm/, net/, sched/: OS 17189 references to the errno variable should always use the set_errno(), 17190 get_errno() macros. 17191 - drivers/, fs/ and libc/: OS references to the errno variable should 17192 always use the set_errno(), get_errno() macros. 17193 17194 * File System/Block and MTD Drivers: 17195 17196 - FAT: CONFIG_FAT_MAXFNAME may not exceed NAME_MAX (CONFIG_NAME_MAX) 17197 - NFS: Correctly infer file type. The file type is in struct 17198 nfs_statinfo_s's ns_type field, not in the ns_mode field. From 17199 Michael Jung. 17200 - NFS: Fix buffer corruption. In case multiple read requests to the 17201 NFS server are required to fill up the user provided buffer, 17202 nfs_read() might write behind the end of said buffer. This is fixed 17203 with this change. From Michael Jung. 17204 - VFS: reopen() should return NULL when oflags is less than 0, not 17205 equal to 0. Because negative value is returned on failure of 17206 lib_mode2offlags() which converts the mode string into file open 17207 mode flag. 17208 - ProcFS: Fix an error in a common function that manages read data. 17209 - drivers/mmcsd: Respect SDIO_CAPS_DMABEFOREWRITE on CMD25. From 17210 Evgeniy Bobkov. 17211 - AT24xx: Correct page size for AT24C02 part. From Alexander 17212 Oryshchenko. 17213 - mtd_config.c: Add still more error handling (to detect bad 17214 underlying flash implementations). Remove MTD_ERASE that was 17215 erasing data block instead of erase block. This is a partial 17216 revert of 4f18b4. Reported-by: Pascal Speck <iktek01@yahoo.com> 17217 17218 * Graphics/Display Drivers: 17219 17220 - drivers/lcd: Fix the default I2C address of SSD1306 OLED display 17221 (7- vs 8-bit addressing) From Alan Carvalho de Assis. 17222 - drivers/lcd: lcd_framebuffer.c does not need to include board- 17223 specific board.h. 17224 - include/lcd: Eliminate a warning from an SSD1306 header file by 17225 adding a forward reference to struct i2c_master_s. From Sebastien 17226 Lorquet. 17227 17228 * Networking/Network Drivers: 17229 17230 - ARP: Fix an error introduced when ICMP and ICMP6 socket support was 17231 added in NuttX-7.3. A gratuitous ARP (or solicitation) was being 17232 sent after receive of the ECHO replay (advertisement). 17233 - ARP: Fix IGMP multicast address computation on Nuttx network stack. 17234 This change fixes the IGMP address computation to allow multicast 17235 UDP messages. The destination address was created with the incorrect 17236 bytes of the given IPv4 address. From Louis Mayencourt. 17237 - ioctl: The existence of the network driver ioctl() method should 17238 depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL. 17239 The former enables the method, the later enables a subset of 17240 possible driver IOCTLs. 17241 - TCP: Write buffering logic should not wait for a free buffer if 17242 the socket was opened non-blocking. 17243 - TCP: Fixed bad return value handling in psock_tcp_send(). send() 17244 expects psock_tcp_send() to return a negated errno value, not -1 17245 with the errno set (GN: I added same change for tcp_send_buffered.c 17246 which has the same issue as tcp_send_unbuffered.c) From Pelle 17247 Windestam. 17248 - TCP: Fixes hardfault when network goes done and network monitoring 17249 is in place. From Gianpaolo Ferroni Ariani. 17250 - TCP: tcp_send_[un]buffered.c: Check routing table in 17251 psock_send_addrchck(). Previously only ARP table was considered 17252 when determining if the data will actually be sent. From Juho 17253 Grundstrom. 17254 - TCP: Generalize Juho Grundstrom's IPv4 change for IPv6 as well. 17255 - UDP: Remove some conditional logic that was true if there is only a 17256 single network device, but not true in the multi-device context. 17257 - UDP: In sendto(), return EHOSTUNREACH if the network is down. 17258 17259 * Common Drivers: 17260 17261 - drivers/pipes: In poll logic, fix off-by-one error in calculation 17262 of bytes in the buffer. Buffer calculation in pipe poll setup is 17263 off-by-one when read index is larger than write index. This causes 17264 poll() not getting POLLIN when buffer has one byte as calculation 17265 gives zero bytes in buffer. From Jussi Kivilinna. 17266 - drivers/audio: Improve stability of the WM8776 driver in SMP mode. 17267 Apply irq_spin APIs to improve performance. Repeat to process a 17268 message to avoid deadlock. From Masayuki Ishikawa. 17269 - drivers/ioexpander: Fixed build of PCF8574 driver when its 17270 interrupts aren't enabled by config. From Dmitriy Linikov. 17271 - drivers/syslog: Fixes LOG_UPTO macro to include specified log level. 17272 From Anthony Merlino. 17273 - drivers/sensors: Fix HTS221 sensor reset with BOOT bit From Jussi 17274 Kivilinna. 17275 - drivers/loop: If we want to open read-only in losetup.c, flags 17276 should be O_RDONLY not O_RDWR. From Fabio D'Urso. 17277 - drivers/timers/ds3231.c: Correct some debug statements. From 17278 Alexander Oryshchenko. 17279 - drivers/sensors/lis2dh: Use realtime clock if monotonic is not 17280 available From Juha Niskanen. 17281 - drivers/i2c and drivers/spi: Fix compile error if 17282 CONFIG_DISABLE_PSEUDOFS_OPERATIONS, fix bad NULL checks From Juha 17283 Niskanen. 17284 17285 * ARMv7-A: 17286 17287 - Data Cache: Fix cp15_invalidate_dcache. In cases where more than 17288 one dcache line was to be invalidated, a missing branch label 17289 would result in a false branch target into cp15_flush_idcache. Also 17290 the .size macro was fixed for both cp15_invalidate_dcache. From 17291 Michael Jung. 17292 - SMP: Port the signal-related SMP change by Masayuki Ishikawa to the 17293 ARMv7-A family. 17294 17295 * Extensa: 17296 17297 - SMP: Port the signal-related SMP change by Masayuki Ishikawa to the 17298 Xtensa family. 17299 17300 * Infineon XMC4xxx Drivers: 17301 17302 - XMC4xxx: Only setup USB clock when USB PLL is enabled From Alan 17303 Carvalho de Assis. 17304 - XMC4xxx: Fix USIC_BRG_SCLKCFG definition From Alan Carvalho 17305 de Assis. 17306 17307 * Microchip PIC32MZ 17308 17309 - MIPS32: In up_idle, the kludge that was conditionally enabled if 17310 the work queue was enable appears to be needed even when he work 17311 queue is not enabled on the PIC32MZ. 17312 - PIC32MZ: Fix some typos in debug instrumentation in pic32mz-gpio.c; 17313 fix some typos related to UART5 configuration in pic32mz-serial.c. 17314 17315 * Microchip/Atmel SAMD/L: 17316 17317 - SPI: In sam_spibus_initialize(), the pinmux configuration was 17318 smashing the previous CTRLA register configuration. There are 17319 also some typos in samd_spi.h From Matt Thompson. 17320 - SPI: Fixes g_spi2ops and g_spi2dev using incorrect values From Matt 17321 Thompson. 17322 - SPI: SPI must be disabled before changing the mode bits in CTRLA 17323 register From Matt Thompson. 17324 - DMA: Fix DMA controller support. From Matt Thompson. 17325 17326 * NXP/Freescale LPC17xx Drivers: 17327 17328 - LPC17xx: Disable LPC17 FDR when not used. If a boot loader set the 17329 fractional divider (FDR) the baud rate in nuttx will be wrong 17330 (multiplied by this fraction). So if it is not used, it should be 17331 disabled. From Harald Gutsche. 17332 17333 * NXP/Freescale Kinetis Drivers: 17334 17335 - Kinetis: Correct some Ethernet PHY register bit tests for the 17336 KSZ8081 PHY. From Stewart. 17337 17338 * On Semiconductor LC823450 17339 17340 - arch/arm/src/LC823450: Add SP_DMB() into lc823450_testset.c. 17341 In LC823450, ldrex and strex are not supported. So we implemented 17342 up_testset() with H/W Mutex. However, there was a bug in memory 17343 access order. This change ensures correct memory access order in 17344 up_testset() for LC823450. From Masatoshi Tateishi. 17345 17346 * STMicro STM32 Drivers: 17347 17348 - STM32 F3 RCC: A flash wait state configuration. Flash latency must 17349 be fixed according to sysclk frequency. If this operation is not 17350 done or done after PLL configuration, the STM32 fail to continue 17351 boot operation if the frequency if greater than 24MHz according to 17352 the board variable STM32_SYSCLK_FREQUENCY. Tested on stm32f334-disco 17353 board. From Gwenhael Goavec-Merou. 17354 - STM32 RTC: Make STM32 usable with an external RTC. 17355 - STM32 SPI: Removed unnecessary (and incorrect) speed limitation. 17356 From Alexander Oryshchenko. 17357 - STM32 SPI: I have a SPI bus with both Mode 0 and Mode 3 devices 17358 on it. After performing SPI I/O to a Mode 0 device, switching to a 17359 Mode 3 device locked up the SPI interface. Only zeroes would be 17360 read. I traced the reason for the lock-up to arm/arm/src/stm32f7/stm32_spi.c function spi_setmode(). Changing 17361 the mode causes a spurious SPI clock transmission that confuses the 17362 stm32f7 SPI input hardware. This problem is solved by (1) changing 17363 the SPI mode with SPI (and perhaps DMA) disabled, and (2) flushing 17364 the receive FIFO if the mode change results in garbage in the FIFO. 17365 From Bob Feretich. 17366 - STM32 and STM32 F7: Remove confusing, redundant, and misleading 17367 definitions of STM32_BKP_BASE from the F2, F3, and F4 memory 17368 maps. Unlike the F1, these parts do not have a separate BKP address 17369 region. The BKP registers are with the RTCC address regions. 17370 stm32_bkp.h should only be used for STM32 F1. stm32_rtcc.h should be 17371 used to access BKP registers on F2, F3, and F4. 17372 - STM32 and STM32 F7: Architecture-specific code is not permitted to 17373 modify the errno variable. 17374 - STM32 F4 I2C: Correct some recent changes to STM32F4 I2C that broke 17375 poll mode of operation. From Alexander Oryshchenko. 17376 - STM32 F4 I2C: Corrections to STM32 F4 I2C to restore functionality. 17377 From Alexander Oryshchenko. 17378 - STM32 F4 I2C: Corrections to STM32 F4 I2C to fix the NORESTART 17379 flag. From Alexander Oryshchenko. 17380 - STM32 F7: Fixes a bug in multi-block SD-card operations on the 17381 STM32F7 platform. DBLOCKSIZE must be the size of SD-card block, not 17382 the total amount of transferred bytes. From Evgeniy Bobkov. 17383 - STM32 F7: Fix undefined variable when using USART1 for other 17384 purposes than UART (e.g. SPI). From Frank Benkert. 17385 - STM32 F7: Backport RTC alarm setting changes from STM32L4. Most 17386 notably this fixes RTC getting stuck issue when both alarms were 17387 used. Root cause was writing RTC ISR register contents to RTC CR 17388 register. From Juha Niskanen. 17389 - STM32 L4 Flash: Change flash programming to use page buffer for 17390 unaligned writes. From Juha Niskanen. 17391 17392 * STMicro STM32 Boards: 17393 17394 - Nucleo-L432KC: Fix some bogus logic noted by Fanda. 17395 - configs/nucleo-* and configs/stm32l476vg-disco: Fix more 17396 stm32_userleds.c bogus logic From Juha Niskanen. 17397 - Nucleo-L432KC: Fixed nucleo-l432kc broken build when 17398 CONFIG_USERLED_LOWER defined From Fanda. 17399 - Nucleo-L432KC: Issue #85: /dev/userleds is not working for 17400 Nucleo-L432KC fixed From Fanda Vacek. 17401 - STM32F429I-Disco: Separate SPI4 from MTD init. I was trying to 17402 attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4 17403 port and was hitting compilation problems, since CONFIG_MTD and 17404 thus 'struct mtd_geometry_s' was not defined. This patch separates 17405 SPI4 initialization logic from MTD initialization logic. From 17406 Michael Jung. 17407 - STM32F103-Minimum: Remove CONFIG_NX_LCDDRIVER dependence from 17408 stm32_ssd1306.c From Alan Carvalho de Assis. 17409 17410 * C Library/Header Files: 17411 17412 - libc/stdio: In dtoa(), up_interrupt_context() is used in a debug 17413 assertion. up_interrupt_context() is not available in the user-mode 17414 phase of the PROTECTED or KERNEL build configurations. In those 17415 configurations, enabling libc floating point support and debug 17416 assertions will result in an undefined reference to 17417 up_interrupt_context(). 17418 - libc/netdb: Fixed parsing of DNS response packets having compressed 17419 names ending with pointer. There were troubles parsing response 17420 packets which have compression of QNAME/NAME field when only 17421 trailing part of the name (not the whole name) is replaced with 17422 pointer to another part of the packet. This commit fixes parsing of 17423 such packets. Also I added checks to keep parsing only in bounds of 17424 the read part of DNS response packet. From Dmitriy Linikov. 17425 17426 * Tools 17427 17428 - tools/*.c: Add #define _GNU_SOURCE to all C files that call 17429 asprintf() to eliminate a warning. 17430 - tools/cvsparser.c: Add a check to avoid access past the end 17431 of a fixed size array 17432 17433 * NSH: apps/nshlib: 17434 17435 - apps/nshlib: Fix compile error when CONFIG_NSH_DISABLESCRIPT is not 17436 defined. The field np_flags does not exist if scripting is disabled. 17437 17438 * Examples/Tests: apps/examples: 17439 17440 - apps/examples/touchscreen: Eliminate BOARDIOC_TSCTEST_SETUP. 17441 17442 * Network Utilities: apps/netutils: 17443 17444 - apps/netutils/ftpc: Fix some corner-cases that could cause FTP to 17445 access past the end of valid data. 17446 17447 * Wireless Utilities: apps/wireless: 17448 17449 - apps/wireless/ieee802154/i8shark: Fixes special XBee compensation 17450 by purposely chopping off the FCS. From Anthony Merlino. 17451 17452NuttX-7.25 Release Notes 17453------------------------ 17454 17455The 125th release of NuttX, Version 7.25, was made on June 3, 2018, 17456and is available for download from the Bitbucket.org website. Note 17457that release consists of two tarballs: nuttx-7.25.tar.gz and 17458apps-7.25.tar.gz. These are available from: 17459 17460 https://bitbucket.org/nuttx/nuttx/downloads 17461 https://bitbucket.org/nuttx/apps/downloads 17462 17463Both may be needed (see the top-level nuttx/README.txt file for build 17464information). 17465 17466Additional new features and extended functionality: 17467 17468 * File Systems/Block and MTD Drivers 17469 17470 - fs/cromfs: Added CROMFS file system. CROMFS is a commpressed, in- 17471 memory, read-only file system based on LZF. 17472 - fs/vfs: Added support for checking if a descriptor is a socket in 17473 fstat(). From Pelle Windestam. 17474 17475 * Graphics/Display Drivers: 17476 17477 - drivers/lcd: Remove support for the Nokia6100 LCD. That LCD uses a 17478 9-bit SPI interface (the 9th bit being the command/data bit that is 17479 normally a discrete). That communication was never successfully 17480 integrated. I now believe that it would would require some special 17481 support from the low-level, MCU SPI driver to manage that 9th bit. 17482 The deleted code is still available in the Obsoleted repository. 17483 17484 * Networking/Network Drivers: 17485 17486 - net/tcp: Added support for TCP Keepalive, add SO_KEEPALIVE socket 17487 option. Added socket options needed to manage TCP-keepalive and TCP 17488 state machine logic to detect if that the remote peer is alive. 17489 - net/tcp: In tcp_input(), add the logic to detect, decode, and 17490 respond to TCP Keep-Alive packets. 17491 - net/tcp: Extended support for sending to non-blocking tcp sockets. 17492 From Pelle Windestam. 17493 - net/bluetooth: Added support for AF_BLUETOOTH sockets. 17494 - drivers/net: Added TAP (network bridge) mode to tun.c. In the 17495 previous implementation, TAP mode did not handle a packet correctly. 17496 Also, the driver did not set the link layer type and could not 17497 assign the interface name. This change fixes such issues and supports 17498 TAP mode correctly. From Masayuki Ishikawa. 17499 17500 * Wireless/Wireless Drivers: 17501 17502 - wireless/ieee802154: Added basic MAC support for RX-ENABLE.request 17503 primitive From Anthony Merlino. 17504 - wireless/ieee802154: Added MAC ackreq flag to TX descriptor for use by 17505 radio driver. The radio layer is responsible for a full "transaction". 17506 Because of differences in radio capabilities, the radio must be 17507 responsible for the handling of acks and retransmissions. This commit 17508 simply passes the ackreq meta-data flag along to the radio. Also 17509 Fixes bug where primitive was freed when it shouldn't have been, 17510 causing double free call. From Anthony Merlino. 17511 - wireless/bluetooth: Bring in the Bluetooth stack from the Intel/ 17512 Zephyr arduino101_firmware_source-v1.tar package. 17513 - drivers/bluetooth: Added re-architected version of the Bluetooth 17514 UART driver from the Intel/Zephyr arduino101_firmware_source-v1.tar 17515 package. 17516 - include/nuttx/wireless: Added a setbaud() method to the HCI UART 17517 lower half interface that can be used to change the default BAUD 17518 selection. 17519 - wireless/bluetooth and include/nutt/net: Added support for Bluetooth 17520 IOCTL commands. 17521 - drivers/wireless/bluetooth: Added a NULL device to support some very 17522 low level testing on the Simulator. 17523 - drivers/wireless/cc3000: Eliminate support for the CC3000 wireless 17524 part because it doesn't use the USRSOCKET. From Alan Carvalho de 17525 Assis. 17526 - drivers/wireless/ieee80211: Added BCM43428 support. From hhuysqt. 17527 17528 * Other Common Device Drivers: 17529 17530 - drivers/1wire: Added 1-wire subsystem and ds28e17 driver From Juha 17531 Niskanen. 17532 - drivers/1wire: Added PM hooks and unlink support to sht21 sensor 17533 (allowing hot-swappable I2C bus from 1-wire converter). Unlike most 17534 other unlink implementations in NuttX drivers, this one does not 17535 allow any I2C operations after unlink, making it possible to 17536 deallocate the I2C bus. From Juha Niskanen. 17537 - drivers/i2c: Added support for the pca9540bdp i2cmultiplexer. From 17538 Giorgio Gro�. 17539 - drivers/power: Added pm_unregister From Juha Niskanen. 17540 - drivers/power: Added generic upper-half motor driver From Mateusz 17541 Szafoni. 17542 - drivers/rgbled: Added support for multichannel PWM (multiple PWM 17543 channels on a single timer) From Anthony Merlino. 17544 - drivers/sensors: Added support for Sensirion SHT2x humidity sensor. 17545 From Juha Niskanen. 17546 - drivers/sensors: Added LSM330 SPI and ADXL372 drivers along with the 17547 - drivers/sensors: Added support for INA3221 power sensor. This has a 17548 3 channel bus/shunt voltage pairs. From Anthony Merlino. 17549 cluster driver infrastructure. From Bob Feratich. 17550 - drivers/sensors: Added multiple MAX31855 sensors feature support. 17551 From Tiago Almeida. 17552 - drivers/wireless/cc1101.c: Driver improvements from from lihaichen. 17553 - progmem interface: Discern r/w and erase page sizes. Introduce new 17554 up_progmem_erasesize architecture API to be able to communicate the 17555 read/write page size independently from erase page size. Implement 17556 up_progmem_erasesize for all architectures that already support 17557 progmem, assuming that for those architectures the sizes of both 17558 read/write and erase pages are identical. From Michael Jung. 17559 17560 * Simulation 17561 17562 - configs/sim: Added a configuration that will support some limited 17563 testing of the Bluetooth stack. 17564 17565 * ARM: 17566 17567 - ARM: All ARM architectures now support CONFIG_ARCH_IDLE_CUSTOM. 17568 17569 * MIPS: 17570 17571 - MIPS: All MIPS architectures now support CONFIG_ARCH_IDLE_CUSTOM. 17572 17573 * Infineon XMC4xxx Drivers: 17574 17575 - XMC4: Added SPI support for Infineon XMC45xx microcontroller. From 17576 Alan Carvalho de Assis. 17577 17578 * Infineon XMC4xxx Boards: 17579 17580 - XMC4500-Relax: Added board support for SPI. From Alan Carvalho de 17581 Assis. 17582 17583 * Nordic NRF52: 17584 17585 - NRF52: Initial support for the NRF52 including UART, Timer, and 17586 GPIO support. From Janne Rosberg. 17587 17588 * Nordic NRF52 Drivers: 17589 17590 - NRF52: Added watchdog timer drivers. Includes significant 17591 updates from Levin Li. 17592 - NRF52: Added nRF52 Flash PROGMEM support From Alan Carvalho de 17593 Assis. 17594 17595 * Nordic NRF52 Boards: 17596 17597 - configs/nrf52-pca10040: Added support for the NRF52-PCA10040 board 17598 including LEDs and buttons From Janne Rosberg. 17599 - configs/nrf52-pca10040: Added support for starting the watchdog 17600 timer on the nRF52. From Alan Carvalho de Assis. 17601 - configs/nrf52-pca10040: Added a configuration for testing the 17602 watchdog timer. From Alan Carvalho de Assis. 17603 17604 * NXP Freescale i.MX RT: 17605 17606 - i.MX RT: Brings in basic support for the i.MX RT 1050 'crossover' 17607 SoC. Includes timer and UART support. This port was the joint 17608 effort of Janne Rosberg, Ivan Ucherdzhiev, and myself. I give 17609 credit to Ivan for the kill because he is the one to held on to 17610 the end. From Ivan Ucherdzhiev. 17611 17612 * NXP Freescale i.MX RT Drivers: 17613 17614 - i.MX RT: Added power management hooks. 17615 - i.MX RT: Added eDMA support (unverified). 17616 - i.MX RT: Added Ethernet driver. From Jake Choy. 17617 - i.MX RT: Added cache operations to permit the Ethernet driver to 17618 work with the D-Cache enabled, at least in write-through mode. 17619 Added support for PHY interrupts and PHY IOCTLs. 17620 17621 * NX FreescaleP i.MX RT Boards: 17622 17623 - IMXRT1050-EVK: Added support for booting from the on board HYPER 17624 Flash. From Ivan Ucherdzhiev. 17625 - IMXRT1050-EVK: Added logic to support the board's user LED. From 17626 Jake Choy. 17627 - IMXRT1050-EVK: Added procfs auto-mount support in imxrt_bringup.c. 17628 From Ivan Ucherdzhiev. 17629 - IMXRT1050-EVK: Added LIBCXX test configuration. 17630 - IMXRT1050-EVK: Added support for the imxrt1050-evk button. From 17631 Jake Choy. 17632 - MXRT1050-EVK: Added support for on-board NOR FLASH boot. From 17633 Ivan Ucherdzhiev. 17634 - IMXRT1050-EVK: Disable LED support because pins conflict with PHY. 17635 Enable device statistics. Enable NSH ifup and ifdown commands. 17636 Added an NSH configuration for testing Ethernet. 17637 17638 * NXP Freescale Kinetis: 17639 17640 - K28F: Added architecture support for the Kinetis K28F. 17641 17642 * NXP Freescale Kinetis Drivers: 17643 17644 - SDHC: Make Kinetis SDHC pullups work the same as the STM32 SDIO 17645 pullups. 17646 17647 * NXP Freescale Kinetis Boards: 17648 17649 - Freedom-K28F. Added support for the Kinetis Freedom-K28F board. 17650 17651 * NXP LPC17xx: 17652 17653 - LPC17xx: Added support for ARMv7-M run time stack checking on NXP 17654 LPC17xx MCUs based on CONFIG_ARMV7M_STACKCHECK. Basically copied 17655 from STM32. From Michael Jung. 17656 17657 * NXP LPC17xx Drivers: 17658 17659 - LPC17xx: Added a configurable option to allow using a part of 17660 LPC17xx's internal flash memory as a Memory Technology Device via 17661 NuttX' mtd_progmem infrastructure. Tested with LPC1769. From 17662 Michael Jung. 17663 17664 * NXP LPC17xx Boards: 17665 17666 - Olimex-LPC1766STK: Remove support for the Nokia6100 LCD. That 17667 LCD uses a 9-bit SPI interface (the 9th bit being the command/data 17668 bit that is normally a discrete). That communication was never 17669 successfully integrated. 17670 17671 * NXP LPC43xx Boards: 17672 17673 - configs/bambino-200e: Added support for multiple MAX31855 sensors 17674 to the bambino-200e. From Tiago Almeida. 17675 17676 * OpenRISC 17677 17678 - arch/or1k/src. Added basic architectural support for the OpenRISK 17679 mor1kx architecture. The initial commit was verified on a Qemu 17680 simulation but is otherwise untested. From Matt Thompson. 17681 17682 * OpenRISC Board 17683 17684 - configs/or1k. OpenRISK mor1kx Qemu simulation. From Matt Thompson. 17685 17686 * STMicro STM32: 17687 17688 - STM32: Added support for the STM32F401xB and STM32F401xC families. 17689 17690 * STMicro STM32 Drivers: 17691 17692 - STM32 HRTIM: Added HRTIM software capture trigger, added software 17693 reset trigger, added outputs polarization configuration From 17694 raiden00pl. 17695 - STM32 ADC: Added ADC injected channels configuration. From Mateusz 17696 Szafoni. 17697 - STM32 HCIUART: Added a Bluetooth HCI UART lower half driver for the 17698 STM32. 17699 - STM32 HCIUART: Implement the setbaud() method for the STM32 HCI 17700 UART interface. 17701 - STM32 SDIO: Added support for SDIO card to SDIO driver. From 17702 hhuysqt. 17703 - STM32 SDIO: Added internal pull-up option for SDIO pins. From Alan 17704 Carvalho de Assis. 17705 - STM32 F2/F4 ADC: Added Vbat measurement to ADC driver for 17706 STM32F20xx and STM32F4xxx. As with the MCU temperature and VREFINT 17707 measurement, this change requires user to enable the corresponding 17708 channel first. For Vbat channel the ioctl cmd is 17709 IO_ENABLE_DISABLE_VBAT_CH, and its arg should be a pointer to bool 17710 which must be true to enable and false to disable the Vbat channel. 17711 Moreover, since Vbat input contains a built-in voltage divider, it 17712 is highly suggested to disable Vbat input channel after measurement 17713 is done in order to prevent battery drain through the divider. From 17714 Dmitriy Linikov. 17715 - STM32, STM32L4 1WIRE: Added one bit read and write to 1-wire 17716 interface. This is needed for devices that require single bit 17717 timeslot generation and for 1-Wire search algorithm triplets. From 17718 Juha Niskanen. 17719 - STM32 F3 SPI: Enable DMA for SPI on stm32f30xxx MCUs. From Michal 17720 Lyszczek. 17721 - STM32 L4 1WIRE: Ported 1wire driver from STM32. From Juha 17722 Niskanen. 17723 - STM32 L4 I2C/SPI/1WIRE: Added PM hooks to I2C, SPI and 1-wire From 17724 Juha Niskanen. 17725 - STM32 F7 RTC: Added CONFIG_RTC_PERIODIC support. Also makes the RTC 17726 lowerhalf more like in STM32L4. From Juha Niskanen. 17727 - STM32 F7 ADC/I2C/SPI: Added PM hooks to ADC, I2C and SPI. From 17728 Juha Niskanen. 17729 17730 * STMicro STM32 Boards: 17731 17732 - Indium-F7: Removed support for the Indium-F7 board. This was done 17733 for two reasons: (1) The board support was just clone of the 17734 Nucleo-144 board support with naming changes. There has been no 17735 support and no further development for the board support. (2) There 17736 does not seem to be any available Indium-F7 board available to the 17737 public anywhere on the Internet. There is not even a reference to 17738 the board on the rafresearch.com web stie. 17739 - Nucleo-L452RE: Added buttons example From Juha Niskanen. 17740 - Nucleo-L476RG: Added support to Nokia LCD PCD8544 on nucleo-l476rg. 17741 From Alan Carvalho de Assis. 17742 - Nucleo-L476RG: Added nxdemo configuration to nucleo-l476rg using 17743 PCD8544. From Alan Carvalho de Assis. 17744 - Olimex-STM32-P407: Added a zmodem test configuration. 17745 - Olimex-STM32-P407: Added the module configuration. 17746 - Photon: Added RGB led support From Anthony Merlino. 17747 - STM32F103-Minimum: Added support for DFU bootloader From Simon 17748 Piriou. 17749 - Spark: Removes Spark board configuration. Still available in the 17750 Obsoleted repository. If there is no CC3000 support, then there is 17751 no purpose in supporting the Spark either. 17752 - STM32F334-Disco: Added buck/boost converter example configuration. 17753 From Mateusz Szafoni. 17754 - STM32F4 Discovery: Added support for multiple MAX31855 sensors to the 17755 STM32F4 Discovery From Tiago Almeida. 17756 - STM32F4 Discovery: Added support in bring-up logic to initialize the 17757 HCI UART and register the HCI UART network device. 17758 - STM32F4 Discovery: Added MAX7219 support to STM32F4Discovery board. 17759 From Alan Carvalho de Assis. 17760 - STM32F4 Discovery: Added board configuration for CS43L22 audio 17761 example. From Alan Carvalho de Assis. 17762 - STM32F4 Discovery: Added a module configuration for testing the 17763 kernel module example with the STM32F4Discovery board. From Alan 17764 Carvalho de Assis. 17765 - STM32F429I-DISCO: Added a LittlevGL configuration for stm32f429i- 17766 disco. From seyyah. 17767 - STM32F746G-DISCO. Added clang support to stm32f746g-disco board. 17768 From Goran Mekic. 17769 - STM32L1 Discovery: Added support for the STM32L152RCT6 version of 17770 the board. 17771 17772 * TI TMS570: 17773 17774 - TMS570: Added support for the TMS570LS3137ZWT. From Ivan Ucherdzhiev. 17775 17776 * TI TMS570 Boards: 17777 17778 - configs/tms570ls31x-usb-kit: Added support for the TI Hercules 17779 TMS570LS31x USB Kit From Ivan Ucherdzhiev. 17780 17781 * TI Tiva: 17782 17783 - CC3200: Remove all support for the CC3200. This was a port that was 17784 started but never completed. What good is partial CC3200 support 17785 with no wireless support?. 17786 17787 * TI Tiva Drivers: 17788 17789 - EEPROM: Implements an EEPROM driver in compliance with MTD driver 17790 as provided by NUTTX for TM4C1294. The EEPROM driver currently 17791 supports only two functionalities - read bytes(multiple of 4) and 17792 write bytes (multiple of 4). From Shirshak Sengupta. 17793 - FLASH: Implemented Flash CONFIG_MTD_BYTE_WRITE for TM4c1294. 17794 Implemented the tiva_write function which will write an arbitrary 17795 number of bytes to flash (in multiple of 4). From Shirshak Sengupta. 17796 - Serial: Added TERMIOS IOCTL support to the Tiva serial driver. 17797 From Dmitry Sharihin. 17798 17799 * TI Tiva Boards: 17800 17801 - CC3200-Launchpad: Remove all support for the CC3200-Launchpad. 17802 This was a port that was started but never completed. What good is 17803 partial CC3200-Launchpad board support with no wireless support?. 17804 17805 * Libraries/Header Files: 17806 17807 - libs/: Moved all of the libraries under a common directory called 17808 libs/ (libc, libnx, and libxx). This almost certainly break libcxx 17809 for now. 17810 - libs/libc/time: Added an implementation of clock(). 17811 - libs/libc/lzf: Added a modified version of Marc Alexander Lehmann's 17812 LIBLZF3.6 library From Boris Astardzhiev. 17813 - libs/libc/unistd: Initial, minimal implementation of sysconf(). 17814 Only sufficient to support the functionality of less standard 17815 getdtabilesize(). From Michael Jung. 17816 - libs/libdsp: Added DSP support library. From Mateusz Szafoni. 17817 - include/sys: Added resource.h. 17818 - include/nuttx/video: Add overlay support to framebuffer interface 17819 definition. From Marco Krahl. 17820 17821 * Tools: 17822 17823 - tools/gencromfs.c: Added tools/gencromfs.c, a tool that can be used 17824 to generate CROMFS file system images. 17825 - tools/mkromfsimg.sh: Include an option in mkromfsimg.sh to ignore 17826 FAT/RAMDISK. This permits you to build tiny systems with ROMFS but 17827 with the rather large FAT FS support. From Alan Carvalho de Assis. 17828 - tools/nxstyle.c: Added check for blank lines before and after single 17829 line comments. From Bob Feretich. 17830 - tools/sethost.sh: Added support for macOS. 17831 - tools/uncrustify.cfg: An initial cut at an uncrustify C formatting 17832 script from Gregory Nutt. Updated, corrected, and verified. From 17833 Bob Feretich. 17834 17835 * Build System: 17836 17837 - Makefile: Added support for nconfig frontend for 'make nconfig'. 17838 From Michal Lyszczek. 17839 - configs/: Added definition of strip to many Make.defs files. 17840 - staging/: Remove fixed lib/ subdirectory and its content. Replace 17841 with new directory called staging/ that is created dynamically when 17842 building and removed when 'make clean' is done. This both improves 17843 the naming and eliminates a garbage directory from the repository. 17844 - tools/: Move all build-related files (except the top-level Makefile) 17845 into the tools/ sub-directory. This really cleans up the top-level 17846 directory. 17847 17848 * NSH: apps/nshlib: 17849 17850 - apps/nshlib: Added the mkfatfs -r option which can be used to 17851 specify the number of entries in the FAT12/FAT16 root directory. 17852 From Boris Astardzhiev. 17853 17854 * Examples/Tests: apps/examples: 17855 17856 - apps/examples/adxl372_test and lxm330spi_test: Added ADXL372 and 17857 LSM330 tests. From Bob Feretich. 17858 - apps/examples/cc3000: Removed the CC3000 example. From Alan 17859 Carvalho de Assis. 17860 - apps/examples/cromfs: Added an example of how to build a CROMFS 17861 file system image. 17862 - apps/examples/elf: Extend the ELF program module demo so that you 17863 can use compressed ELF programs with CROMFS. 17864 - apps/examples/elf: Use strip command to make ELF binaries MUCH 17865 smaller. Added an option to strip debug symbols even if the debug 17866 symbols are enabled in the base code. 17867 - apps/examples/max31855: Added an example to read multiple max31855 17868 sensors. From Tiago Almeida. 17869 - apps/examples/netloop: Update network loopback example so that it 17870 can be used to test TCP KeepAlive. 17871 - apps/examples/nxdemo: Added nxdemo application From Alan Carvalho 17872 de Assis. 17873 - apps/examples/powerled: Added arch initialization. 17874 - apps/examples/uavcan: Removed because apps/canutils/libuavcan is no 17875 longer available. 17876 17877 * System Utilities: apps/system 17878 17879 - apps/system/lzf: Added the test case from Marc Alexander Lehmann's 17880 LIBLZF3.6 librrary From Boris Astardzhiev. 17881 - apps/system/embedlog: Support for embedlog data loggin package from 17882 https://embedlog.kurwinet.pl/ From Michal Lyszczek. 17883 - apps/system/zmodem: Added an option to enable hardware flow control 17884 via termios. Allow stack size and priority to be configured. 17885 - apps/system/zmodem: Call tcflush() before closing the serial port. 17886 This is necessary because that close operation may hang if hardware 17887 flow control is enabled. Consider this scenario: After the host 17888 sz runs on the host, it exits and leaves CTS high. The target rz 17889 completes, and tries to close the serial port. But if there is 17890 buffered Tx data, then the close will hang when it tries to drain 17891 the buffered Tx data since there is no where it can go. tcflush() 17892 discards the buffered data and permits the close to continue. 17893 There is additional logic in nuttx/drivers/serial needed to work 17894 with this. 17895 17896 * CAN Utilities: apps/canutils: 17897 17898 - apps/canutils/libuavcan. Removed! libuavcan has not built for a 17899 year or so. The basic problem is that as NuttX advances, the old 17900 frozen version of libuavcan has become absolute because it violates 17901 the portable POSIX OS interface. No one is maintaining the port so 17902 there is no alternative but to remove it. 17903 17904 * Network Utilities: apps/netutils: 17905 17906 - apps/netutils/tftpc: Modified the TFTP client functions to use a 17907 data read/write callback instead of a file. This allows TFTP to 17908 write to arbitrary destination (in my case, a MTD device - for 17909 firmware update). Two new functions are introduced for this, named 17910 tftpget_cb and tftpput_cb. They are just made of most of the 17911 existing code. The previously existing tftpget/tftpput functions 17912 are now wrappers on the new ones, with callbacks that read/write 17913 from files, so my modifications are backwards compatible with 17914 existing applications, eg the associated nsh commands dont need to 17915 be changed. From Sebastien Lorquet. 17916 17917 * Wireless Utilities: apps/wireless: 17918 17919 - apps/wireless/bluetooth/btsak: Added a Bluetooth debug tool. 17920 17921Bugfixes. Only the most critical bugfixes are listed here (see the 17922ChangeLog for the complete list of bugfixes and for additional, more 17923detailed bugfix information): 17924 17925 * Core OS: 17926 17927 - sched/sched: Fix a deadlock in SMP mode. Two months ago, I 17928 introduced sched_tasklist_lock() and sched_tasklist_unlock() to 17929 protect tasklists in SMP mode. This change works well for HTTP 17930 audio streaming aging test with lc823450-xgevk. However, I found a 17931 deadlock in the scheduler when I tried similar aging tests with DVFS 17932 autonomous mode where CPU clock speed changed based on cpu load. In 17933 this case, call sequences were as follows. To avoid this deadlock, 17934 I added sched_tasklist_unlock() when calling up_cpu_pause() and 17935 sched_addreadytorun(). Also, added sched_tasklist_lock() after the 17936 call. Also added critical sections to lib_filesem.c, mm_sem.c, and 17937 net_lock.c for SMP for SMP. From Masayuki Ishikawa. 17938 - sched/sched: Change ordering of round-robin time slice check 17939 (sched_process_scheduler()) and processing of wdog timers 17940 (wd_timer()). wd_timer()'s callback function can change current 17941 running task and, hence, must be done after the time slice check. 17942 The time slice check will decrement the currently running task's 17943 time slice allotment. If such a context switch occurs, then the 17944 newly started task will lost one could of that allotment before it 17945 even has a chance to run. From EunBong Song. 17946 17947 * File System/Block and MTD Drivers: 17948 17949 - fs/fat: In fs_stat(), when stat'ing the root directory, avoid 17950 calculating the address of the root directory entry. The 17951 calculation is bogus (but not harmful) because the root directory 17952 does not have a directory entry. Noted by Boris Astardzhiev. 17953 - fs/fat: Avoid calculating the bogus directory entry address for 17954 the FAT root directory (since it has no directory entry). This 17955 change should have no effect, other than making the logic clearer. 17956 From Boris Astardzhiev. 17957 - fs/mount: Fix wrong size reported by df -h. Reason is that size 17958 in bytes is calculated always on uint32_t types and cards bigger 17959 than 4GB will overflow uint32_t type. Solution is to use uint64_t 17960 where possible. From Michal Lyszczek. 17961 - fs/smartfs: Fix a hardfault in SmartFS. Problem occurred when 17962 opening a file with O_CREAT (only) when the file arelready exists 17963 but has a size of zero. From Michal Lyszczek. 17964 - fs/vfs: Fix negative errno set in fs_open.c From Michal Lyszczek. 17965 - drivers/mtd: Fixed a W25 driver w25_cacheflush sector bug. From 17966 lihaichen. 17967 - drivers/mtd: mtdconfig_register() returned OK instead of -ENOMEM on 17968 failed allocation. From Michal Lyszczek. 17969 17970 * Graphics/Display Drivers: 17971 17972 - drivers/lcd/ft80x: ACTIVE host command appears to be formatted 17973 differently than other host commands; Fix ROM CHIPID. Appears to 17974 be big-ending, BCD. Fix some compile issues when debug features 17975 are enabled. 17976 - drivers/lcd/ft80x: Fix a typo that caused the driver to fail to 17977 recognize the ft801 chip version. From Gregory Nutt. 17978 - Review all board implementations of board_lcd_initialize(). The 17979 NuttX convention is that all internal functions that return errors 17980 as an 'int' must return a negated errno value on failure and a non- 17981 negative value on success. Most were right but eight of them had 17982 cloned logic that returns 1 on success and zero on failure. both 17983 of which are interpreted as success by the caller since they are 17984 non-negative. 17985 17986 * Networking/Network Drivers: 17987 17988 - net/tcp: Fixed problem with send() retrun value when using 17989 nonblocking I/O over buffered tcp socket From Dmitriy Linikov. 17990 - net/sixlowpan: Fix a nasty, byte-ordering/endian-ness problem. 17991 The root cause has been found and corrected. And a half dozen 17992 or so bandaid fixes were reverted. 17993 - net/sixlowpan: Preserve big-endian (network order) when 17994 uncompressing address. From Anthony Merlino. 17995 - net/sixlowpan: TCP send should have PSH and ACK flags set when 17996 sending. This matches the standard network (Ethernet) TCP send 17997 logic. From Anthony Merlino. 17998 - net/udp: Fix several issues using connected UDP sockets: sendto() 17999 should not accept an address. Normally send() should be used with 18000 connect UDP sockets instead. recvfrom() is no longer necessary. 18001 recvfrom() and poll() should not reset to accept any addresses but 18002 should, instead, only accept inputs and events from the connected 18003 remote peer. On of these issues was noted by ??? 18004 <liguiding@pinecone.net>. Changes were made as summarized here: 18005 http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch08lev1sec11.html 18006 From Gregory Nutt. 18007 - net/udp: Resolve race condition in connection-less UDP sockets with 18008 read-ahead buffering. In connection-mode UDP sockets, a remote 18009 address is retained in the UDP connection structure. This 18010 determines both there send() will send the packets and which packets 18011 recv() will be accepted. This same mechanism is used for 18012 connection-less UDP sendto: A temporary remote address is written 18013 into the connection structure to support the sendto() operation. 18014 That address persists until the next recvfrom() when it is reset to 18015 accept any address. When UDP read-ahead buffering is enabled, 18016 however, that means that the old, invalid remote address can be left 18017 in the connection structure for some time. This can cause read- 18018 ahead buffer to fail, dropping UDP packets. Shortening the time 18019 between when he remote address is reset (i.e., immediately after the 18020 sendto() completes) is not a solution, that does not eliminate the 18021 race condition; in only makes it smaller. With this change, a flag 18022 was added to the connection structure to indicate if the UDP socket 18023 is in connection mode or if it is connection-less. This change 18024 effects only UDP receive operations: The remote address in the UDP 18025 connection is always ignored if the UDP socket is not in connection- 18026 mode. No for connection-mode sockets, that remote address behaves as 18027 before. But for connection-less sockets, it is only used by sendto(). 18028 18029 * Wireless/Wireless Drivers: 18030 18031 - drivers/wiresless/ieee80211: Correct some initialization problems 18032 with BCM43362 chip. From hhuysqt. 18033 - drivers/ieee802154/xbee: Added a timeout to send logic to handle 18034 case where XBee module fails to respond to a Transmit request with 18035 a Transmit Status From Anthony Merlino. 18036 18037 * Common Drivers: 18038 18039 - Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and 18040 debug wrappers -- does not return a value. Rename _vsyslog to 18041 nx_vsyslog. Use internal nx_vsyslog in the few cases where a 18042 return value is required. 18043 - drivers/leds: Fixes RGB LED issues caused by uninitialized memory 18044 with CONFIG_RGBLED_MULTICHAN. The uninitialized pwm_info_s struct 18045 caused a rogue channel to be started causing errors in the pwm 18046 driver From Anthony Merlino. 18047 - drivers/sensors/lis2dh: Clear INT1 at SNIOC_WRITE_INT1THRESHOLD 18048 ioctl. From Jussi Kivilinna. 18049 - drivers/sensors/sht21: Changed I2C_TRANSFER return value so that 18050 it return on zero on success, not the count of bytes transferred. 18051 From Juha Niskanen. 18052 - drivers/serial: Per Matias Edlund: I recently used the tcflush 18053 function and found that it failed with ENOTTY. The reason is that 18054 the TCFLSH case in the function uart_ioctl in the file 18055 drivers/serial/serial.c does not update the ret value." On 18056 success, the TCFLSH IOCTL logic needs to explicitly set the return 18057 value (ret) to zero. 18058 - drivers/serial: Added a timeout to uart_tcdrain(). Even if 18059 tcflush() is used to discard buffered data, the close() can still 18060 hang if (a) hardware flow control is enabled, (b) CTS == 1, and 18061 (c) there is data stuck in the hardware Tx FIFO. tcflush() does 18062 not currently clear the MCU serial drivers' hardware Tx FIFOs. 18063 This is a workaround for that. 18064 - drivers/sensors: Fix APDS9960 work queue BUG found by Kyle Lei. 18065 From Alan Carvalho de Assis. 18066 18067 * Simulator: 18068 18069 - arch/sim: Various fixes necessary to build the simulator under 18070 MSYS2. 18071 18072 * ARMv7-R: 18073 18074 - ARMv7-R: Corrected several ARMv7-R issues. From Ivan Ucherdzhiev. 18075 18076 * Infineon XMC4xxx Boards: 18077 18078 - XMC4500-Relax: Call xmc4_spidev_initialize() in xmc4_boot.c. From 18079 Alan Carvalho de Assis. 18080 18081 * NXP/Freescale LPC17xx Drivers: 18082 18083 - LPC17xx USB: Fix USB device endpoint allocation bookkeeping. From 18084 Michael Jung. 18085 - LPC17xx USB: Freeing endpoints should be set the same allocations 18086 as when endpoint was allocated. 18087 - LPC17xx USB: Fix loss of RX initiatives. USB bulk endpoints are 18088 double buffered on LPC17xx MCUs. This means that up to two packets 18089 might be received on an OUT endpoint that can not be handled 18090 immediately if the receive request queue is empty. Thus, 18091 rxpending must be a counter not a boolean flag. From Michael Jung. 18092 18093 * NXP/Freescale Kinetis Drivers: 18094 18095 - Kinetis USG: USB device fixes: Use correct CONFIG OTG control, 18096 Fix interrupt storm when cable is disconnected. The DM, DP state 18097 were incorrect because the pulldowns were not enabled. Also the 18098 pending asynchronous resume interrupt needed to be re-armed after 18099 the suspend is in effect. This is now done in the isr. From David 18100 Sidrane. 18101 - Kinetis Serial: In kinetis_lowputc.c, fix esBRFA calculation 18102 effecting baudrate. Previous BRFA was not cleared and or-ed into 18103 new BRFA, hence, buadrate was wrong. Where Baud Rate Fractional 18104 Divisor (BRFD) UART baud rate = clock / (16 * (SBR + BRFD)). From 18105 David Sidrane. 18106 - Kinetis Serial: In kinetis_lowputc.c, fixed parity settings. 18107 Kinetis UART must be placed in 9 bit mode (M=1) with when 8 bit data 18108 with parity is required. If left in 8 bit mode (M=0) with parity 18109 then D7 of the TX/RX register becomes parity bit. Hence what is 18110 called 9-bit or 8-bit Mode Select is a misnomer. 8 bit mode when 18111 parity is enabled is realy 7 bit with parity. From David Sidrane. 18112 18113 * NXP/Freescale Kinetis Boards: 18114 18115 - configs/teensy-3.x: Remove CONFIG_USBDEV_DUALSPEED from the usbnsh 18116 configuration. Hardware supports only FS. 18117 18118 * NXP i.MX6 Drivers: 18119 18120 - i.MX6: Bring in a few i.MX6 fixes that were committed to similar 18121 files for the i.MX RT. 18122 18123 * STMicro STM32: 18124 18125 - STM32 F3: Problem: stm32f30xx hangs waiting for LSE to initialize. 18126 Reason for hang is that operation of setting LSE_ON does not take 18127 effect because there is no clock on PWR peripheral. This is 18128 initialized later in the code From Michal Lyszczek. 18129 18130 * STMicro STM32 Drivers: 18131 18132 - STM32 and STM32 L4 1WIRE: In 1wire driver, do not write useless 18133 WRITEBIT zero return value to const buffer From Juha Niskanen. 18134 - STM32 HRTIM: Fixed capture_get function,. From raiden00pl. 18135 - STM32 F3 ADC: Fixed bug in RCC reset logic that resets ADC1 18136 configuration when both ADC1 and ADC2 are in use From Mateusz 18137 Szafoni. 18138 - STM32 Ethernet: In case of PHY failure, usually because of the 18139 lack of 25/50 MHz REFCLK input, the Ethernet block would lock up 18140 in a while loop waiting for readiness, which will never happened. 18141 This prevented the board from starting at all in the case of a PHY 18142 failure. This commit adds a retry loop to avoid bricking the board 18143 if the Ethernet block is unable to start. From Sebastien Lorquet. 18144 - STM32 F7 SDMMC: Added support for the second SDMMC device. The 18145 second SDMMC device was already supported but the clock was never 18146 enabled. This fixes that. From William Douglas. 18147 - STM32 Serial: Fix UART glitch when lowputc is enabled. From 18148 Simon Piriou. 18149 - STM32 USB: Skip recipient check for descriptor related 18150 requests From Simon Piriou. 18151 18152 * TI Tiva Drivers: 18153 18154 - Tiva ADC: Fix compilation errors on Tiva ADC code when ADC is 18155 enable. From Vinicius Maciel. 18156 - Tiva Serial: Allow building of Tiva platform with no serial 18157 console. From Dmitry Sharihin. 18158 18159 * C Library/Header Files: 18160 18161 - lib/libc/netdb: Fixed boundary conditions in dns_recv_response(). 18162 Fixed typos in include/nuttx/net/dns.h. From Masayuki Ishikawa. 18163 - libs/libc/modlib: Fixed backward test for an error in 18164 modlib_verify.c. 18165 18166 * Build System: 18167 18168 - Makefiles: Eliminate the spurious errors reported by 'make 18169 savedefconfig'. 18170 - Makefile(s): There is a sort command in the 'make savedefconfig' 18171 file. I found that sort behaves differently on different platforms 18172 based on the environment variable LC_ALL. Now, Makefile.unix will 18173 force LC_ALL=C just for the sort command so that we can all generate 18174 equivalent defconfig files. 18175 - Makefile(s): The clean_context target needs to invoke a 18176 corresponding clean_context target in the apps/Makefile in order to 18177 remove linkages. From Gregory Nutt. 18178 - LibTargets.mk, tools/Config.mk: Drop executable bit on installed 18179 libraries. The rules to install libraries under lib/ were modified 18180 to use mode 0644 instead of the default 0755. From Andrey Zabolotnyi. 18181 18182 * Examples/Tests: apps/examples: 18183 18184 - apps/examples/ft80x: Fix some size calculations. Added option to 18185 disable primitive tests. just too boring to have to watch over and 18186 over again. Fix a typo in backlight fade logic; Fix error in 18187 formatted display light debug dump output. 18188 - apps/examples/ft80x: Text is handled by the coprocessor and, hence, 18189 must use RAM_CMD, not RAM_DL. 18190 - apps/examples/ft80x: Fix some errors in co-processor demos. Correct 18191 an error in the spinner demo. 18192 - apps/examples/nsh and posix_spawn: Must not call exec_setsymtab() 18193 directly. That is a non-POSIX internal OS interface. 18194 - apps/examples/ostest: Do not call AIO test without 18195 CONFIG_EXAMPLES_OSTEST_AIO From Juha Niskanen. 18196 - apps/examples/smps: Fix typos in Kconfig. All power, voltage, 18197 current values were strings with no default. I assume they should 18198 be 'int' with what default?. 18199 - apps/examples/smps: Fixes in some printf and in Kconfig From 18200 Mateusz Szafoni. 18201 - apps/system/zmodem: Fix Makefile.host. It was broken when zmodem.h 18202 was moved to apps/include/system. Fix an incompatibility with the way 18203 that CRCs are calculated. 18204 18205 * System Utilities: apps/system: 18206 18207 - apps/system: Applications should use the standard clock() interface, 18208 not the internal NuttX clock_systimer() interface. 18209 - apps/system/stackmonitor: Fix comparison between pointer and zero 18210 character constant. From Juha Niskanen. 18211 18212 * Network Utilities: apps/netutils: 18213 18214 - apps/netutils/netlib: Various fixes needed to get a clean netlib 18215 build with Bluetooth only. 18216 18217 * Wireless Utilities: apps/wireless: 18218 18219 - apps/wireless: Applications should use the standard clock() 18220 interface, not the internal NuttX clock_systimer() interface. 18221 18222NuttX-7.26 Release Notes 18223------------------------ 18224 18225The 126th release of NuttX, Version 7.26, was made on September 8, 2018, 18226and is available for download from the Bitbucket.org website. Note 18227that release consists of two tarballs: nuttx-7.26.tar.gz and 18228apps-7.26.tar.gz. These are available from: 18229 18230 https://bitbucket.org/nuttx/nuttx/downloads 18231 https://bitbucket.org/nuttx/apps/downloads 18232 18233Both may be needed (see the top-level nuttx/README.txt file for build 18234information). 18235 18236Additional new features and extended functionality: 18237 18238 * Core OS: 18239 18240 - General: Eliminate use of the non-standard type systime_t and 18241 replace it the equivalent, standard type clock_t From Gregory Nutt. 18242 - General: Replace non critical PANIC with DEBUGPANIC to save the 18243 code space From Xiang Xiao. 18244 - General: Replace all ASSERT with DEBUGASSERT to save the code 18245 space From Xiang Xiao. 18246 - Initialization: Add option to mount block device for 18247 INIT_FILEPATH case. From anchao. 18248 - clock(): clock_systimer() is no longer a system interface. It has 18249 been replaced with the equivalent, standard interface clock(). 18250 Moved the implementation of clock() from the C library into the OS 18251 core. This is necessary because it calls the (now) internal OS 18252 function clock_systimer(). clock() is now accessed only via a 18253 system call in certain configurations. From Gregory Nutt. 18254 - clock Utilities: Move clock_timespec_[add|subtract] to 18255 include/nuttx/clock.h From Xiang Xiao. 18256 - Binary Loader: Add binfmt_initialize(). All binary formats are 18257 now registered centrally vs. in board-specific logic. This 18258 simplifies the usage of the binfmt subsystem. From Xiang Xiao. 18259 - Binary Loader: Reference default symtab name to binfmt From anchao. 18260 - mm: Add mm_heapmember function and reimplement kmm_heapmember base 18261 on mm_heapmember since this function is very useful if multiple 18262 heaps exist. From Xiang Xiao. 18263 - mm: Add {kumm/kmm}_calloc API. Add calloc API for manage user 18264 memory and kernel memory in Flat Build/Kernel Build without kernel 18265 heap. From zhuyanlin. 18266 - pthreads: Add support static pthread stack. Add standard 18267 pthread_attr_setstack() and pthread_attr_getstack(). In all cases 18268 where the stack is released, add check to see which allocator must 18269 be used to free the stack: The user or the kernel allocator. From 18270 xuanlin. 18271 - Semaphores: Apply the semaphore wait function 18272 nxsem_wait_uninterruptible(). This function is a wrapped version 18273 of nxsem_wait() that is uninterruptible and convenient for use. 18274 From liuhaiyang. 18275 - Signals: Add default signal action to SIGKILL. From ligd. 18276 - Signals: Update the signal default action logic to support 18277 sigaction(). signaction() must be able to handle and input action 18278 of SIG_DFL to setup the default signal action; it mast also return 18279 SIG_DFL it is replacing the default action. From Gregory Nutt. 18280 - Signals: Default Signal Actions. Change some types to 18281 superficially simplify. Add configuration options to enabled 18282 default signal behaviors on a per-signal basis. I don't think 18283 users are prepared for SIGALRM to terminate the task (which is the 18284 correct default behavior if you don't change it). Extend the 18285 implementation of default signals so that it is totally table 18286 driven and extensible by simply mondifying the content of const 18287 tables. From Gregory Nutt. 18288 - Signals: Add support for SIGINT in addition to SIGKILL. 18289 - Signals: Add logic and an interface to determine if a signal can 18290 be caught or ignored. sigaction now correctly returns EINVAL on 18291 any attempt to catch or ignore such signals (only SIGKILL for now 18292 and only if CONFIG_SIG_DEFAULT=y). From Gregory Nutt. 18293 - Signals: Add support for default signal actions for SIGSTOP, 18294 SIGSTP, and SIGCONT. Add procfs support to show stopped tasks. 18295 From Gregory Nutt. 18296 - Signals: Add nxsig_action() to solve a chicken and egg problem: 18297 We needed to use sigaction to set default actions, but sigaction() 18298 would refuse to set actions if the default actions could not be 18299 caught or ignored. From Gregory Nutt. 18300 - Signals: Add configuration option to selectively enabled/disable 18301 default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT. 18302 - Signals: If a task/thread was already blocked when 18303 SIGSTOP/SIGSTP was received, it will restart in the running state. 18304 It will appear that to the task/thread that the blocked condition 18305 was interrupt by a signal and returns the EINTR error. From 18306 Gregory Nutt. 18307 - Signals: Update signal default STOP action. If waitpid was 18308 called with the WUNTRACED then wake up waitpid(). From Gregory 18309 Nutt. 18310 - IRQs: Monitor the IRQ execution time. This is very useful for 18311 measuring the interrupt latency. From Xiang Xiao. 18312 - IRQ Dispatch: Add support interrupt chains in NuttX. IRQ chain is 18313 very useful in these cases: (1) Multiple hardware connect to the 18314 same request line(e.g. PCI), (2) Need multiple driver to support 18315 one hardware block (like Linux MFD) From zhuguangqing. 18316 - Work Queue: Modify high priority work queue to support multiple 18317 threads. From ligd. 18318 - System Calls: Add support for getpeername() and get_sockname() 18319 system calls. From Gregory Nutt. 18320 - System Calls: svcall/sycall logic needs to get the ucontext 18321 argument from R4 instead of stack since all syscall parameters pass 18322 from registers in syscall.h From Xiang Xiao. 18323 - CPU Load Measurement: Support the CPU load measurement using 18324 timer_lowerhalf_s interface From Xiang Xiao. 18325 - Assertions: Change CONFIG_BOARD_RESET_ON_CRASH to 18326 CONFIG_BOARD_RESET_ON_ASSERT, arch/: Implement call to 18327 board_reset() if in all implementations of up_assert() when 18328 CONFIG_BOARD_RESET_ON_ASSERT=y. From Xiang Xiao. 18329 - boardctl(): Add support for board_app_finalinitialize() From ligd. 18330 - Architecture Interface: Add prototype for an architecture-specific 18331 up_trigger_irq function. From dongjianli. 18332 - Architecture Interface: Add the garbage collection hook so each 18333 architecture can do custom memory cleanup if necessary. From Xiang 18334 Xiao. 18335 - Architecture Interface: Add architecture-specific prototypes for 18336 conversions between physical and virtual address. From ligd. 18337 18338 * File Systems/Block and MTD Drivers 18339 18340 - ProcFS: Add support for a procfs entry that will permit examining 18341 the environment of any task. From Gregory Nutt. 18342 - ProcFS: Add support for proc/self/, a convenient way for getting 18343 information about the currently running task. From Gregory Nutt. 18344 - HostFS: Add support for open() append mode From anchao. 18345 - HostFS: Add ftruncate support. From Xiang Xiao. 18346 - HostFS: Remove ARCH_SIM dependence since other architectures 18347 (e.g., arm semihosting) could support hostfs too From Xiang Xiao. 18348 - HostFS: Support remote directory names without a trailing '/' 18349 From ligd. 18350 - HostFS: Add re-try when hostfs mount() fails From ligd. 18351 - NFS: Update NFS client mount to VER3 From zhangyuan7. 18352 - Partitions: Add PTABLE parser fs/partion: Add a partition parser 18353 framework fs/driver/fs_blockpartition.c: Add 18354 register_blockpartition for block partition From Xiang Xiao. 18355 - MTD: Add gd25 driver From wangyanjiong. 18356 - MTD: In MTD partitions, copy the partition name to internal 18357 buffer so that the caller can free the name argument From Xiang 18358 Xiao. 18359 - MTD: Support initialization of an FTL block device with a custom 18360 name From Xiang Xiao. 18361 - MTD: FTL: Reduce size of stack buffer from 64 to a maximum size 18362 as determined from NAME_MAX. From Gregory Nutt. 18363 - VFS poll(): Send poll() notification when the Tx buffer is flushed 18364 From ligd. 18365 - VFS fstat(): Add file_fstat() function for internal OS use. From 18366 ligd. 18367 - VFS fcntl(): Add file_fcntl, psock_fcntl, and psock_dupsd for use 18368 within the kernel. From Xiang Xiao. 18369 - VFS dup2(): Addpsock_dupsd for use within the kernel. From Xiang 18370 Xiao. 18371 - VFS poll(): Add poll use in kernel space. From dongjianli. 18372 - VFS select(): Make select be more consistent with Linux man page: 18373 'The timeout ... Some code calls select() with all three sets 18374 empty, nfds zero, and a non-NULL timeout as a fairly portable way 18375 to sleep with subsecond precision.' From anchao. 18376 18377 * Networking/Network Drivers: 18378 18379 - Sockets: Add getpeername() support From ligd. 18380 - sockopt(): Move psock check from [get|set]sockopt to 18381 psock_[get|set]sockopt From Xiang Xiao. 18382 - getsockname(): Add psock_getsockname function From Xiang Xiao. 18383 - Netlink Sockets: This brings in a fragmentary, experimental 18384 implementation of NETLINK sockets. There is not too much to that 18385 socket support on this initial commit, just the netlink socket 18386 framework. However, I decided to bring it into master because 18387 there is a enough that I would not want to lose what is in place. 18388 And since it is dependent on CONFIG_EXPERIMENTAL, its presence on 18389 master should be innocuous. From Gregory Nutt. 18390 - Interface Indexes: Add driver interface index support. Add 18391 implementation of if_nametoindex() and if indextoname(). Raw 18392 AF_PACKET sockets now depend on CONFIG_NETDEV_IFINDEX. Add syscall 18393 support for if_nametoindex() and if_indextoname(). Includes an 18394 algorithm to prevent an interface index from being reused until all 18395 network interfaces have by assigned once. The prevents removable 18396 devices from being removed, unregistered and re-installed, 18397 re-registered and keeping the same interface index. From Gregory 18398 Nutt. 18399 - Driver Interface: Add devif_loopback() to check the loopback 18400 case where a packet is being sent to itself. Modify the net driver 18401 to call this function in this case. This function will simply 18402 re-inject the packet back into the network and the network driver 18403 will not put anything on the wire. From Xiang Xiao. 18404 - Network Devices: Remove all references to CONFIG_NET_USER_DEVFMT. 18405 That feature is now unconditionally enabled. This was done because 18406 (1) the feature does not require very much additional memory, and 18407 (2) it causes confusion in the configuration due to the additional 18408 complexity. Any network drivers that fail to zero the device 18409 structure interface name field (d_ifname) because calling 18410 netdev_register() will, however, get a nasty surprise. From 18411 Gregory Nutt. 18412 - Network Devices: Add support for Microchip LAN91C111 driver From 18413 Xiang Xiao. 18414 - Network Devices: netdev_findby_ipv[4|6]addr return 18415 netdev_default() as last resort but don't return loopback device 18416 if another network device is in the UP state. From Xiang Xiao. 18417 - Network Device IOCTLs: Add si_ioctl callback and net_ioctl_arglen 18418 so usrsock could forward the ioctl to the remote end/ From 18419 dongjianli. 18420 - IPv6: Rename g_ipv6_allzeroaddress with the more meaning 18421 g_ipv6_unspecaddr since the all-zero address is the IPv6 18422 unspecified address (sometime IN6_ADDR_ANY). Replace more inline 18423 tests for IPv6 multicast with common net_is_addr_mcast() macro. 18424 From Gregory Nutt. 18425 - ARP: arp_find() now checks if the target IP belongs to one of the 18426 local network devices. From Xiang Xiao. 18427 - ARP: Make the function arp_find() thread-safe. It now returns a 18428 copy of the MAC address from the ARP table entry, rather than a 18429 potentially unstable reference to the ARP table entry. From 18430 Gregory Nutt. 18431 - TCP: Re-work of TCP receive window size algorithm. The new logic 18432 is based only on the ability to buffer TCP read-ahead data. From 18433 Gregory Nutt. 18434 - UDP: Add support for the UDP_BINDTODEVICE protocol socket option 18435 From Sebastien Lorquet. 18436 - Slip: Uncomment the prompt of NET_SLIP_PKTSIZE in Kconfig file. 18437 From Xiang Xiao. 18438 - USRSOCK: Combine some the duplicated logic. From Xiang Xiao. 18439 - USRSOCK: Optimize option dependence From Xiang Xiao. 18440 - USRSOCK: Add the listen/accept/getpeername/ioctl support From 18441 dongjianli. 18442 18443 * Other Common Device Drivers: 18444 18445 - Analog DAC: Add driver for digital to analog converter DAC7571. 18446 Nucleo-L422KC: Add support for a connect DAC7571 converter. From 18447 Daniel Pereira Carvalho. 18448 - Audio Interface: Change member samp of apb to pointer so driver 18449 can customize sample buffer allocation From ZhongAn. 18450 - Audio Interface: Add ioctl cmd 'AUDIOIOC_SETBUFFERINFO' so user 18451 space could config the buffer From ZhongAn. 18452 - Audio Interface: Add hardware format support From anchao. 18453 - I2S Interface: Add i2s_rxchannels and i2s_txchannels methods to 18454 the I2S lower half interface. From ZhongAn. 18455 - Audio: Move the I2S character driver to a dedicated folder. From 18456 Xiang Xiao. 18457 - Audio: Add audio_i2s device driver. From ZhongAn. 18458 - Audio: Add the composite audio driver From Xiang Xiao. 18459 - Crypto: Move dev_urandom.c into new crypto folder. From Xiang 18460 Xiao. 18461 - GPIO driver: Add gpio_pin_unregister function to GPIO driver 18462 driver/ioexpander: Add pinset struct to GPIO driver for interrupt 18463 pins larger than 64. Initialize pintype/inttype when registering 18464 ioexpander device. Add SETPINTYPE ioctl command to the GPIO 18465 driver. From zhuyanlin. 18466 - I2C Interface: Add a definition to distinguish a new START of 18467 messages from a repeated start. No lower-half I2C drivers actually 18468 implement this new flag bit, however. In I2C write/read logic use 18469 new repeated START definition where appropriate. Rename 18470 I2C_M_NORESTART to I2C_M_NOSTART since it may be used in other 18471 contexts than a repeated start. Add comments to clarify setup for 18472 repeated start. From Gregory Nutt. 18473 - I2C: Add the standard speed macros. From dongjiuzhu. 18474 - Leds: Add support to MAX7219 to control 7-segment displays. From 18475 Alan Carvalho de Assis. 18476 - Power: PM: Add pm_stay and pm_relax function so special apps(e.g. 18477 mediaplayer) could disable suspend during playback much like linux 18478 kernel counterpart From Xiang Xiao. 18479 - Power: PM: Add pm_querystate function From zhuguangqing. 18480 - Power: PM: Don't update the power state in work thread: (1) 18481 Simplify the code logic and remove the work queue dependence, (2) 18482 Power calculation is too simple to delay into the work queue From 18483 Xiang Xiao. 18484 - Power: PM: Decrease the power state in the reverse order. Since 18485 the child driver need power off before parent driver. From 18486 zhuguangqing. 18487 - Power: PM: Make power manager service available as soon as 18488 possible: (1) Initialize g_pmglobals at the definition, (2) skip 18489 hold the lock if OS isn't ready From Xiang Xiao. 18490 - Power: PM: Add PM_RESTORE to notify driver that device exit WFI 18491 so the driver could restore state. For example, WDT may stop 18492 counting before enter low power state and restore the counting 18493 again in PM_RESTORE notification From zhuguangqing. 18494 - Power: PM: Add timer to decrease PM level automatically. From 18495 ligd. 18496 - PTYs: Add support so that a PTY can poll for both IN/OUT event 18497 simultaneously. From ligd. 18498 - PWM: Move pwm.c into pwm folder From Xiang Xiao. 18499 - RTC Interface: Extend struct rtc_time by adding. From Xiang 18500 Xiao. tm_nsec if RTC supports hiresolution time. From Xiang Xiao. 18501 - Sensors: Add support for Telair T6713 carbon dioxide sensor. From 18502 Juha Niskanen. 18503 - Sensors: Add support for LSM303AGR and LSM6DSL sensors From 18504 DisruptiveNL. 18505 - Sensors: Add driver for DHTxx sensor. From Ouss4. 18506 - syslog: Enable a partial, crippled version of syslog_flush(); 18507 Call syslog_flush() from assertion handling logic of all 18508 architectures. From Gregory Nutt. 18509 - syslog: Channel configuration. Decouple SYSLOG_SERIAL_CONSOLE and 18510 ARCH_LOWPUTC. Since some hardware can output log to the special 18511 debug channel not serial. From anchao. 18512 - syslog: Support pre-pending a prefix string to log output if 18513 enabled. This very useful to identify which CPU send out the log 18514 in AMP SoC. From anchao. 18515 - Serial: Add Ctrl-C/Ctrl-X support. From ligd. 18516 - Serial: Support UART direct write for non console device From 18517 xuanlin. 18518 - Serial: It is no longer necessary to restrict Ctrl-C handling to 18519 the FLAT build sched/signal: Add a new configuration option to 18520 select signal default actions, separate handling of signal default 18521 actions from both task startup logic and from the serial TTY 18522 Ctrl-C logic. Add a signal set in the group structure to keep 18523 track of what signals have been set to the default action. In 18524 dispatching signals in PROTECTED or KERNEL mode, use this signal 18525 set to determine if the default signal handler is attached and 18526 dispatch the signal in kernel mode for the default actions. From 18527 Gregory Nutt. 18528 - Serial: Integrate new Ctrl-C logic with the ISIG flag in the 18529 termios c_lflag. From Gregory Nutt. 18530 - Serial: Use SIGINT instead of SIGKILL when control-C is pressed. 18531 From Gregory Nutt. 18532 - Serial: Add support for Ctrl-Z. This works just like the 18533 recently added Ctrl-C support except that SIGSTP is sent when the 18534 Ctrl-Z characters is encountered vs. SIGINT. From Gregory Nutt. 18535 - 16550 UART: Add a configuration, analogous to the STM32 18536 configuration option, to suppress the NuttX standard re-ordering 18537 for /dev/ttySN for special case of the 16550 UART. 18538 - 16550 UART: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a 18539 memory mapped device doesn't need to provide uart_getreg() and 18540 uart_putreg() implementations. 18541 - 16550 UART: Add stub implementations of DMA-related methods in the 18542 16550 UART v-table. From ligd. 18543 - 16550 UART: Add serial termios handling From anchao. 18544 - 16550 UART: Support 16550 auto hardware flow control 18545 drivers/serial/uart_16550.c: Add configuration option 18546 CONFIG_16550_SUPRESS_INITIAL_CONFIG. This is identical to the 18547 standard configuration in arch/Kconfig 18548 CONFIG_SUPPRESS_UART_CONFIG, but with scope of only the 16550 18549 driver. From Xiang Xiao. 18550 - syslog: Make timestamp output same as linux kernel. It's very 18551 useful if NuttX syslog retarget to Linux syslog. From Xiang Xiao. 18552 - Timers: Add maxtimeout method to the struct timer_ops_s interface 18553 From Xiang Xiao. 18554 - Timers: Add a new method to the struct oneshot_operations_s 18555 interface to get the current time from a oneshot timer driver (if 18556 it is available from the lower half) From Xiang Xiao. 18557 - Timers: Implement timer arch API on top of timer driver. From 18558 Xiang Xiao. 18559 - Timers: Implement alarm arch API on top of oneshot driver 18560 interface. From Xiang Xiao. 18561 - Timers: Implement RTC arch API on top of RTC driver interface. 18562 From Xiang Xiao. 18563 - CDC/ECM: Adds USB device support for CDC/ECM From Michael Jung. 18564 - USB Host: Add support for the Maxim M3421E USB host driver. Not 18565 yet fully tested. From Gregory Nutt. 18566 18567 * General Architecture-Specific: 18568 18569 - All architectures: Make sure the up_irq_enable() is available on 18570 all architectures. From Gregory Nutt. 18571 18572 * Simulation 18573 18574 - Simulator Configurations: Add dsptest configuration. From Mateusz 18575 Szafoni. 18576 - Simulator: In network driver (1) Remove up_comparemac() check for 18577 matching MAC address. Let's trust that the tap device just return 18578 the packet which belong to us like other real network device 18579 hardware. (2) Add network device statistics support. From Xiang Xiao. 18580 18581 * ARM: 18582 18583 - ARM (all): Add CONFIG_DEBUG_MEMFAULT to Kconfig. From Masayuki 18584 Ishikawa. 18585 - ARM: (1) Add semihost support for syslog, (2) Add semihost support 18586 for HostFS From Gregory Nutt. 18587 18588 * ARMv6-M: 18589 18590 - ARMv6-M: Introduce CONFIG_DEBUG_HARDFAULT_INFO to up_hardfault.c 18591 From Masayuki Ishikawa. 18592 18593 * ARMv7-M: 18594 18595 - ARMv7-M: Removes support for the dedicated vector handling from the 18596 many older architectures. Only common vectors are now supported. 18597 From Gregory Nutt. 18598 - ARMv7-M: Introduce CONFIG_DEBUG_HARDFAULT_INFO to up_hardfault.c 18599 From Masayuki Ishikawa. 18600 - ARMv7-M: Implement SYSTICK timer driver From Xiang Xiao. 18601 - Simulator: Add loadable demo for arch sim. From anchao. 18602 - ARMv7-M: Add logic to trigger ARMv7-M interrupts and exceptions. 18603 From Gregory Nutt (from sample logic by Xiang Xiao). 18604 - ARMv7-M: Add NVIC definitions needed by up_trigger_irq(). From 18605 Gregory Nutt. 18606 18607 * ARMv7-R: 18608 18609 - ARMv7-R: Add general interrupt controller. This is based on 18610 ARMv7-A gic controller code. From EunBong Song. 18611 - ARMv7-R: Add invalidate dcache in arm_head.S. From EunBong Song. 18612 18613 * Infineon XMC4xxx Drivers: 18614 18615 - XMC4 GPIO: Add a specific bit encoding to GPIO driver for 18616 opendrain GPIO pin. From Alan Carvalho de Assis. 18617 18618 * Infineon XMC4xxx Boards: 18619 18620 - XMC4500-Relax: Add support to MAX6675 on XMC4500-Relax board. 18621 From Alan Carvalho de Assis. 18622 18623 * Microchip PIC32MX Boards; 18624 18625 - PIC32MX: Update some PIC32MX configurations so that either the 18626 MPLAB or Penguino toolchains may be used. From Gregory Nutt. 18627 18628 * Microchip/Atmel SAMD2x/L2x: 18629 18630 - SAMD2x/L2x: Rename all usage of samdl/SAMDL to samd2l2/SAMD2L2 to 18631 make room in the name space for samd5e5/SAMD5E5 From Gregory Nutt. 18632 18633 * Microchip/Atmel SAMD5x/E5x: 18634 18635 - SAMD5x/E5: Add a port to the SAMD5x/E5x MCU family. From Gregory 18636 Nutt. 18637 18638 * Microchip/Atmel SAMD5x/E5x Drivers: 18639 18640 - SAMD5x/E5x SPI/I2C: Bring in untested SPI and I2C drivers from 18641 SAMD2L2. From Gregory Nutt. 18642 - SAMD5x/E5x DMA: Leverage the SAMD2L2 DMA controller. From Gregory 18643 Nutt. 18644 - SAMD5x/E5x USB: Bring the SAMDL2 USB driver into the SAMD5E5 18645 port. From Gregory Nutt. 18646 18647 * Microchip/Atmel SAMD5x/E5x Boards: 18648 18649 - Metro M4: Add support for the Adafruit Metro M4 board. From 18650 Gregory Nutt. 18651 - Metro M4: Add an option to build the Metro M4 image to run out of 18652 SRAM. This ought to be a safer and quicker way to do the initial 18653 bring-up (having bricked the first Metro M4 due to a bad FLASH 18654 image). From Gregory Nutt. 18655 - Metro M4: Add a configuration option to use OSCULP32K instead of 18656 XOSC32K. From Gregory Nutt. 18657 - Metro M4: After some final fixes related to the SERCOM console, 18658 the basic NSH configuration appears fully functional. From 18659 Gregory Nutt. 18660 - Metro M4: Verify the CMCC and enable it by default in the NSH 18661 configuration. From Gregory Nutt. 18662 18663 * Microchip/Atmel SAMv7 Drivers: 18664 18665 - SAMv7 CAN: Add ability for CAN BUS_OFF autorecovery according 18666 ISO11898-1:2015. With this change we added an ioctl for triggering 18667 the autorecovery sequence for BUS_OFF to the CAN-driver and the 18668 SAMV7 low-level driver. According the datasheet: If the device 18669 goes Bus_Off, it will set MCAN_CCCR.INIT of its own accord, 18670 stopping all bus activities. Once MCAN_CCCR.INIT has been cleared 18671 by the processor (application), the device will then wait for 129 18672 occurrences of Bus Idle (129 * 11 consecutive recessive bits) 18673 before resuming normal operation. At the end of the Bus_Off 18674 recovery sequence, the Error Management Counters will be reset. 18675 During the waiting time after the resetting of MCAN_CCCR.INIT, each 18676 time a sequence of 11 recessive bits has been monitored, a Bit0 18677 Error code is written to MCAN_PSR.LEC, enabling the processor to 18678 readily check up whether the CAN bus is stuck at dominant or 18679 continuously disturbed and to monitor the Bus_Off recovery 18680 sequence. MCAN_ECR.REC is used to count these sequences. From 18681 Frank Benkert. 18682 18683 * NXP Freescale i.MX RT Drivers: 18684 18685 - i.MXRT RTC: Add support for the i.MXRT RTC. This is code complete 18686 (with limited features and options) but untested. The HPRTC is 18687 functional. However, if the LPSRTC is enabled, then there is a 18688 hang during LPSRTC initialization. It appears that there is some 18689 problem in providing clocking and initializing the LPSRTC domain. 18690 From Gregory Nutt. 18691 - i.MXRT SNVS: Add trivial SNVS from Rev 1. of the Reference Manual. 18692 From Gregory Nutt. 18693 - i.MXRT LSPI: IMXRT1050 LPSPI register and bit definitions added. 18694 From Ivan Ucherdzhiev. 18695 - i.MXRT Serial: IMXRT1050 LPUART TERMIOS support added. From Ivan 18696 Ucherdzhiev. 18697 18698 * NXP Freescale i.MX RT Boards: 18699 18700 - IMXRT1050-EVK: Add knsh configuration. PROTECTED mode NSH build. 18701 From Gregory Nutt. 18702 18703 * NXP Freescale Kinetis: 18704 18705 - Kinetis: Add DMA support. From David Sidrane. 18706 18707 * NXP Freescale Kinetis Drivers: 18708 18709 - Kinetis: Use circular DMA as an option to augment the RX FIFOs in 18710 the Serial driver. From David Sidrane. 18711 18712 * NXP LPC54xx: 18713 18714 - LPC54xx: The LPC54608 can only run at a maximum frequency of 18715 180Mhz. This configuration requires uses the clk_in, external 18716 crystal clock, to drive the PLL. When that input was selected, the 18717 board bootup failed waiting for the PLL to lock. After referring 18718 the driver from NXP, we should turn on power sources for the ext 18719 clock if system pll input select clk_in. NOTE that the LPC54628 18720 did not require this step... perhaps because the system oscillator 18721 power was already enabled. From kxjiang. 18722 - LC823450: Add support for mpu and userspace LC823450-XGEVK: Add 18723 kostest PROTECTED build LC823450-XGEVK: Add knsh PROTECTED build 18724 From Masayuki Ishikawa. 18725 18726 * NXP LPC54xx Boards: 18727 18728 - Lpcxpresso-LPC54628: Update lvgl board config to use the new 18729 version From Alan Carvalho de Assis. 18730 18731 * On Semi LPC23450 Drivers: 18732 18733 - LC823450 Bluetooth: Add lc823450 Bluetooth support. From Masayuki 18734 Ishikawa. 18735 - LC823450 I2S: Add tx start threshold to lc823450_i2s.c In 18736 addition, lc823450_i2s_send() now accepts byte-aligned stream. 18737 From Masayuki Ishikawa. 18738 - LC823450 SPI: Add SPI flash driver for lc823450. NOTE: Only bus 18739 accelerator mode is supported. From Masayuki Ishikawa. 18740 - LC823450: Change C-Buffer under-level control. The under-level 18741 setting was changed from 1KB to 55KB. In previous implementation, 18742 the setting can be changed by the tx threshold but it is fixed at 18743 startup. Also, check write size and adjust alignment if needed. 18744 From Masayuki Ishikawa. 18745 18746 * On Semi LPC23450 Boards: 18747 18748 - LC823450-XGEVK: Add loopback test for digital MIC on lc823450 via 18749 i2schar driver. From Masayuki Ishikawa. 18750 - LC823450-XGEVK: Add lc832450 elf test. From Masayuki Ishikawa. 18751 - LC823450-XGEVK: Add posix_spawn configuration From Masayuki 18752 Ishikawa. 18753 18754 * STMicro STM32: 18755 18756 - STM32 L4: Add initial support to STM32L4+ chips From Juha Niskanen. 18757 - STM32 H7: A partial port to the STMicro STM32H7 by Simon Laube was 18758 brought in from the PX4 repositories. Numerous changes were 18759 make(by Mateusz Szafone). The basic STM32 H7 NSH configuration is 18760 now functional, thanks to Mateusz Szafoni. 18761 18762 * STMicro STM32 Drivers: 18763 18764 - STM32 F0, F1-F4, F7, L4, H7: Added Single Wire Kconfig variable. 18765 From David Sidrane. 18766 - STM32 DAC: Set OUTEN bit for DAC1CH2 and DAC2CH1 power/motor. 18767 Direction parameter is now int8 + add overload fault. From Mateusz 18768 Szafoni. 18769 - STM32 F1-F4 ADC: Allow multiple channels without DMA on 18770 STM32L15XX. From Juha Niskanen. 18771 - STM32 F1: Add FLASH register definitions for F1 parts that have 18772 dual banked FLASH.

That driver was 18779 same as the STM32 F4 driver. From Gregory Nutt. 18780 - STM32 F7: Port input capture from stm32. From Juha Niskanen. 18781 - STM32 F7 FLASH: Ported the STM32 F2/F4 driver to the STM32 F7 18782 platform. From Evgeniy Bobkov. 18783 - STM32 F7 SDMMC: Add SDIO card support to SDMMC driver. From 18784 Ramtin Amin. 18785 - STM32 F7 Serial: Previous logic would invalidate the data cache as 18786 each byte was read from the DMA buffer. This change adds logic to 18787 invalidate the data cache less frequently by monitoring the state 18788 of the Rx DMA buffer cache coherency and invalidating only regions 18789 as necessary. From Evgeniy Bobkov. 18790 - STM32 F7: Add up_stackcheck.c From Daniel Agar. 18791 - STM32 F7: Port the low-level PM functions to STM32 F7. From Juha 18792 Niskanen. 18793 - STM32 L4: STM32L4 has fetchadd and testset From Juha Niskanen. 18794 - STM32 L4: Added custom pin mapping for STM32L4X2XX processors. 18795 From Daniel P. Carvalho. 18796 - STM32 L4 FLASH: stm32l4xrxx: allow board to override flash wait 18797 states From Juha Niskanen. 18798 - STM32 L4: Some updates to analog peripherals ADC, COMP and DFSDM 18799 for STM32L4XR From Juha Niskanen. 18800 - STM32 L4: Add getstatus and getperiod() method to the timer 18801 driver (includes coding standard changes made prior to commit) 18802 From Goden Freemans. 18803 - STM32 H7: Remove old references to RXDMA. Add configuration 18804 - STM32 H7: Remove old references to RXDMA. Add configuration 18805 option to select the Rx FIFO threshold level.

From Mateusz Szafoni. 18816 - STM32F4-Discovery: Remove STM32F4BB dependence from RNDIS; add 18817 RAMDISK support. From Alan Carvalho de Assis. 18818 - STM32F4-Discovery Add board support for MAX7219 as numeric display 18819 controller. From Alan Carvalho de Assis. 18820 - Olimex-STM32-P407: Add kernel ELF (kelf) configuration. From 18821 Gregory Nutt. 18822 - Olimex-STM32-P407: Add a kmodule configuration that can be used 18823 for testing installation of kernel modules in the protected build. 18824 From Gregory Nutt. 18825 - Olimex-STM32-P407: Add logic to support initialization of the 18826 kernel module symbol table installed in the pass1/ directory during 18827 the application phase of the build. The kmodule configuration 18828 appears to be fully functional. From Gregory Nutt. 18829 - Olimex-STM32-P407: Add board support for the DHTxx sensor. From 18830 Ouss4. 18831 - STM32F476G-DISCO: Add support for STM32F746G-disco board LCD. 18832 From Marcin Wyrwas. 18833 - STM32F476G-DISCO: Add a configuration to build working nxdemo 18834 application From Fanda. 18835 - STM32F476G-DISCO: Add support for STM32F746G-disco board SDRAM 18836 Changed fb config to use SDRAM.

From 18855 Gregory Nutt. 18856 - libc unistd: Add a crippled version of daemon(). From Gregory Nutt. 18857 - libdsp: All floats with f-sufix libdsp: (1) add precision option 18858 for library, (2) add debug option for library and assertions in 18859 functions, (3) add current samples correction for SVM3, (4) add 18860 some motor control specific functions, (5) add basic speed 18861 observer, (6) fix phase shift in SMO observe, (7) add more logic to 18862 FOC. From Mateusz Szafoni. 18863 - include/nuttx/compiler.h, include/poll.h: Add logic to determine 18864 if the compiler supports anonymous structures and unions. From 18865 Gregory Nutt. 18866 - include/nuttx/mutex.h: Add inline wrapper functions to more 18867 clearly support semaphores when used as mutexs. From QianWenfa. 18868 - include/nuttx/nuttx.h: Added nuttx.h header file which is 18869 analogous to the linux.h header file. Currently, it contains on 18870 the definition of the container_of() macro. From zhuyanlin. 18871 - include/queue.h: Add dq_tail marco From zhuguangqing. 18872 - include/stdio.h: Add prototypes for popen() and pclose(). Actual 18873 implementation is in apps/system/popen() From Gregory Nutt. 18874 - include/sys/param.h: Add a dummy sys/param.h header file. This is 18875 not a standard file but is used by other systems and having the 18876 dummy file may minimize some porting efforts. From Gregory Nutt. 18877 18878 * Tools: 18879 18880 - nuttx/tools/kconfig2html.c: Due to new usage, tool needs to be 18881 able to handle configuration files with names other than Kconfig. 18882 From Gregory Nutt. 18883 - nuttx/tools/kconfig2html.c: Update tool to handle tristate types. 18884 From Gregory Nutt. 18885 - nuttx/tools/Config.mk: Add function CATFILE definition. Currently 18886 only used in apps/builtin/Makefile. From Gregory Nutt. 18887 - nuttx/tools/Config.mk: Add the recursive wildcard function, 18888 RWILDCARD, to Config.mk. From Gregory Nutt. 18889 - nuttx/tools/testbuild.sh: Add an option to specify the location of 18890 nuttx directory. From Gregory Nutt. 18891 - nuttx/tools/refresh.sh: Add a --prompt option that will let you 18892 use --silent but will prompt before overwriting the original 18893 defconfig. From Gregory Nutt. 18894 - nuttx/tools/link.sh. Update link.sh per suggestions by Mark so 18895 that it can be used with MSYS vs copydir.sh. From Gregory Nutt. 18896 - nuttx/tools/mkexport.sh: Save the System.map file and User.map 18897 file (if it exists) in the export package so that it can be used to 18898 extract addresses. From Gregory Nutt. 18899 - nuttx/tools/mkexport.sh: Save the name of the STRIP tool too. From 18900 Gregory Nutt. 18901 - nuttx/tools/nxstyle.c: Add capability to detect multiple blank 18902 lines. Single spacing required by the coding standard. Also coding 18903 standard fixes to server .c files for problems found during testing 18904 nxstyle. From Gregory Nutt. 18905 - apps/tools: Add +x to mksymtab.sh. From Masayuki Ishikawa. 18906 - apps/tools/define.sh and define.bat: Move a copy of define.bat 18907 and sh from nuttx/tools to apps/tools so that they will be 18908 available for the import build. From Gregory Nutt. 18909 18910 * Build System: 18911 18912 - Apps/ Build System. The apps/ build system has undergone a major 18913 renovation to better support building applications as ELF modules. 18914 Module selections have changed from 'bool' to 'tristate' types. 18915 This means that building an ELF now is as simple setting the value 18916 to 'm'. This effort required many changes, too many to summarize 18917 here. The solution was contributed by Masayuki Ishikawa, Anchao 18918 An, and Xiang Xiao (and myself to a lesser extent). 18919 - NuttX/ Build System: This change extends support for the two-pass 18920 build. Its primary purpose is to incorporate source logic 18921 generated by applications into the kernel phase of the build. 18922 In the two pass build, the application logic is built during the 18923 first phase, pass 1. In that phase, the application may generate 18924 and install source files in the pass1/directory. The operating 18925 system is built during phase 2 of the build. At that time, those 18926 source files in the pass1/ directory will be built and incorporated 18927 into the kernel address space. 18928 The primary purpose of the pass1/ directory is to such 18929 application-generated kernel symbol tables. For an example of the 18930 use of this feature, look at 18931 apps/examples/module/drivers/Makefile. Kernel symbol tables are 18932 needed to support kernel modules. Of course, addition 18933 board-specific logic in, say, configs/<board>/src would have to be 18934 included to make use of the application-installed symbol tables. 18935 From Gregory Nutt. 18936 - Remove CONFIG_ARCH_CALIBRATION. It is awkward to use and no longer 18937 necessary now that we have apps/examples/calib_udelay. From 18938 Gregory Nutt. 18939 - Build System: With recent changes to apps/ all configurations that 18940 build applications as modules must now also select 18941 CONFIG_APPS_LOADABLE. From anchao. 18942 - Build System: Add dynamic application loadable support. From 18943 anchao. 18944 - Build System: Add configuration CONFIG_ARCH_GNU_NO_WEAKFUNCTIONS 18945 to suppress use of weak functions. Some gnu derived toolchains do 18946 not support weak symbols. From Xiang Xiao. 18947 - Kconfig: Move 'option modules' from NSH_FILE_APPS to 18948 BUILD_LOADABLE From anchao. 18949 - apps/ Build System: Introduce a build system for loadable apps 18950 for nsh. Add 'option modules' to NSH_FILE_APPS so that a user can 18951 change an application configuration to tristate (y/n/m) 18952 - apps/import: Add Makefile.symtab which can be used to compile the 18953 dynamically created symbol table C file. Also adds 18954 tools/mksymtab.sh. From Gregory Nutt. 18955 18956 * NSH: apps/nshlib: 18957 18958 - apps/nshlib: Add parsing support for back-slash quoted 18959 characters. Currently only implemented properly if 18960 CONFIG_NSH_ARGCAT is also selected. This commit is in response to 18961 Bitbucket Issue 11 opened by Maciej W�jcik From Gregory Nutt. 18962 - apps/nshlib: Add inverted logic support in the form of 'if ! 18963 <cmd>' From Beat K�ng. 18964 - apps/nshlib: Expand reboot and poweroff commands to include a 18965 second, optional mode argument From ligd. 18966 - apps/nshlib: Add a force flag (-f) to mksmartfs command. SmartFS 18967 will be formatted only if (1) the FLASH does not already hold a 18968 SmartFS, or (2) the force flag is set. From Xiang Xiao. 18969 - apps/nshlib: NSH prompt string is now configurable. nsh> is 18970 still the default. From Xiang Xiao. 18971 - apps/nshlib: Add control-C support for terminating built-in and 18972 exec'ed file tasks. From ligd. 18973 - apps/nshlib: Call BOARDIOC_FINALINIT after start-up script (or 18974 immediately after BOARIOC_INIT is there is no start-up script). 18975 From ligd. 18976 - apps/nshlib: When using waitpid() to wait for a built-in 18977 application or a file application to exit. Add the WUNTRACED 18978 options to so the the waitpid() call will also be awakened if the 18979 waited-for task is stopped as well. From Gregory Nutt. 18980 18981 * NSH Builtins: apps/builtin: 18982 18983 - apps/builtin/Makefile. This commit changes apps/builtin to search 18984 the registry recursively. By supporting directories, external 18985 projects can install the hooks into the registry and easily clean 18986 them up and reinstall if something needs to be updated. Based on 18987 an idea from Anthony Merlino. From Gregory Nutt. 18988 18989 * Examples/Tests: apps/examples: 18990 18991 - apps/examples/calib_udelay: Add tool for calibrating 18992 CONFIG_BOARD_LOOPSPERMSEC From Juha Niskanen. 18993 - apps/examples/dhtxx: Example for the DHTxx sensor. From Ouss4. 18994 - apps/examples/dsptest: Add unit test for Nuttx DSP library From 18995 Mateusz Szafoni. 18996 - apps/examples/elf: CROMFS and ROMFS configuration currently only 18997 usable in FLAT build. Add configuration to use ELF objects on 18998 external media like SD card or USB drive instead. From Gregory 18999 Nutt. 19000 - apps/examples/elf: If the test ELF files are on media in 19001 removable media such as SD or USB FLASH, the wait until the media 19002 has been installed and initialized before starting the test. From 19003 Gregory Nutt. 19004 - apps/examples/fb: Adds example to test framebuffer overlay From 19005 Marco Krahl. 19006 - apps/examples/gps: Add GPS example using MINMEA lib From Alan 19007 Carvalho de Assis. 19008 - apps/examples/i2sloop: Add i2sloop application. This application 19009 can be used to test I2S loopback like: ' nsh> i2sloop &'. From 19010 Masayuki Ishikawa. 19011 - apps/examples/lvgldemo: Update LVGL to version 5.1.1 From Alan 19012 Carvalho de Assis. 19013 - apps/examples/module: Add support for CROMFS and for stripping 19014 symbols from ELF module binaries. From Gregory Nutt. 19015 - apps/examples/module: Add support for automounting removable media. 19016 This involves a wait for the block driver to become available 19017 before performing the mount. From Gregory Nutt. 19018 - apps/examples/module: When built in the PROTECTED or KERNEL 19019 modes, the symbol table is not built by the application. That is 19020 because the build will fail since the kernel module depends on 19021 internal OS symbols thar are not available to the application 19022 build. With this change the examples does not attempt to build 19023 the kernel symbol table in these modes. Instead it just copies 19024 the kernel module symbol table into the nuttx/pass1 directory 19025 where it can be build directly into the OS during pass2 of the 19026 build. From Gregory Nutt. 19027 - apps/examples/ostest: Add a small test for SIGSTOP, SIGCONT, and 19028 SIGKILL actions. From Gregory Nutt. 19029 - apps/examples/popen: Add a test of popen/pclose. From Gregory 19030 Nutt. 19031 - apps/examples/powerled: Add arch initialization. From Mateusz 19032 Szafoni. 19033 - apps/examples/tcpblaster: Add TCP performance measurement test. 19034 From Gregory Nutt. 19035 19036 * System Utilities: apps/system 19037 19038 - apps/system/cle: Usage improvements including command line 19039 history (taken from readline) and support for addition control 19040 characters. From mst. 19041 - apps/system/i2c: Adapt to rename I2C_M_RESTART->i2C_M_START. 19042 I2C_M_NOSTOP should be in flags of first message in every 19043 write-read and write-write mesage sequence. From Gregory Nutt. 19044 - apps/system/i2c: Allow registers besides 0x00 in the dev command. 19045 From Jakob Haufe. 19046 - apps/system/nsh: Add logic to automatically register an 19047 application symbol table as part of NSH initialization. From 19048 Masayuki Ishikawa. 19049 - apps/system/nsh: The symbol table name and size variable names 19050 can now be configured. From Gregory Nutt. 19051 - apps/system/nsh: Move apps/examples/nsh to apps/system/nsh. It 19052 has become so entrenched that it is hardly an example these days. 19053 May as well formalized it as a system task. From Gregory Nutt. 19054 - apps/system/nxplayer: Refactor nxplayer.c. Apply 19055 netlib_parsehttpurl() and 19056 remove unnecessary usleep(). From Masayuki Ishikawa. 19057 - apps/system/nxplayer: Release buffer before session and release 19058 semaphore in nxplayer_setvolume system/nxplayer/nxplayer.c: 19059 Remove & for apb->samp reference. It is already a pointer. From Xiang Xiao. 19060 - system/nxplayer/nxplayer.c: Add playraw command From ZhongAn. 19061 - apps/system/nxrecorder: Add nxrecorder application From ZhongAn. 19062 - apps/system/popen: Add an implementation of the standard popen() 19063 and pclose() OS interfaces. These are implemented as applications 19064 vs. part of the OS because they depend on NSH. Untested on 19065 initial commit. From Gregory Nutt. 19066 - apps/system/system and popen: Adapt so that these can be used in 19067 the KERNEL build mode. In this case, simply replace task_spawn() 19068 with posix_spawn(). This depends on the existence of some 19069 environment where /bin/sh exists and can be used to execute one 19070 NSH command. For the case of system(), this change was more 19071 complete because it previously used task_create(). Now it uses 19072 either task_spawn() or posix_spawn(), depending upon the 19073 configuration. From Gregory Nutt. 19074 - apps/system/taskset: Add taskset command for SMP systems. This 19075 command can be used to retrieve or set a process's CPU affinity. 19076 For example, 19077 19078 nsh> taskset -p 4 19079 pid 4's current affinity mask: 2 19080 19081 nsh> taskset -p 3 4 19082 pid 4's current affinity mask: 3 19083 19084 nsh> taskset -p 1 busyloop & 19085 19086 From Masayuki Ishikawa. 19087 - apps/system/zmodem: Support -p <path> for rz to change the folder 19088 for the received file. Switch debug output from printf to 19089 syslog. Send the next packet for ZME_ACK in ZMS_SENDING to avoid 19090 rz on the host side stuck make send work reliable even without 19091 hardware flow control. From Xiang Xiao. 19092 19093 * Network Utilities: apps/netutils: 19094 19095 - apps/netutils/dhcpc: Activates BINDTODEVICE if available. From 19096 Sebastien Lorquet. 19097 19098 * Wireless Utilities: apps/wireless: 19099 19100 - apps/wireless/i8sak: i8sak daemon now gets shutdown if not in use. 19101 Previously, once the i8sak daemon was started, by running any 19102 command, it would stay running. This means that if you want to use 19103 i8sak to setup your network, but then want exclusive access to the 19104 char device, or network device, you have to manually shutdown the 19105 i8sak daemon. Now the daemon stays active as long as required to 19106 finish any commands, or stays open if a new command keeps it on, 19107 but when all work is finished, it shuts down. From Anthony Merlino. 19108 19109 * Filesystem Utilities: apps/fsutils: 19110 19111 - mkfatfs: Clean up some name BS_ and MBR_ refer to the same record 19112 and should use the same naming (MBR_). From Gregory Nutt. 19113 - mkfatfs: Add definitions for the FAT boot record (FBR). From 19114 Gregory Nutt. 19115 - mksmartfs: Add a check to see if the SmartFS is already 19116 formatted. From Xiang Xiao. 19117 19118 * Graphic Utilities: apps/graphics: 19119 19120 - graphics/littlevg/: Update LVGL to version 5.1.1 From Alan 19121 Carvalho de Assis. 19122 19123 * Test Utilities: apps/testing: 19124 19125 - testing/unity: Add Unity - unit testing library from 19126 ThrowTheSwitch.org. From Mateusz Szafoni. 19127 19128Bugfixes. Only the most critical bugfixes are listed here (see the 19129ChangeLog for the complete list of bugfixes and for additional, more 19130detailed bugfix information): 19131 19132 * Core OS: 19133 19134 - Signals: Signal handlers maybe run with interrupts enabled or 19135 disabled, depending on how the task the received the signal was 19136 blocked. (i.e.: If sem_wait() is called, then we disable 19137 interrupts, then block the currently running task). This could be 19138 dangerous, because user code would be running with interrupts 19139 disabled. 19140 This change forces interrupts to be enabled in up_sigdeliver() 19141 before executing the signal handler calling up_irq_enable() 19142 explicitly. This is safe because, when we return to normal 19143 execution, interrupts will be restored to their previous state when 19144 the signal handler returns. From Gregory Nutt (Based on a 19145 recommendation by Mark Shulte). 19146 - Signals: Lock the scheduler while while killing the children so 19147 that we do not lose priority and let the task group continue to 19148 run in an indeterminate state. From Gregory Nutt. 19149 - Groups: Fix a deadlock when loading an ELF From Masayuki Ishikawa. 19150 - Groups: In some circumstances, group_killchildren() could have 19151 called pthread_cancel() to kill a task. Also, the behavior would 19152 not be as expected if a pthread had cancellation disabled. From Gregory Nutt. 19153 - Posix Message Queues: mq_notify() fix - only part of struct copied 19154 to internal structure. As source address the address of the struct 19155 member sigev_value was used, and it is not located the start of the 19156 struct. This leads to invalid data being copied to internal 19157 structure. Both source and destination should be of type struct 19158 sigevent* . From Simon Liedl. 19159 - vfork(): vfork operation needs to allocate and copy the task 19160 argument too. Also correction of the address correction cannot 19161 depend on the stack pointer since it is not available in all 19162 architectures. Rather calculate the offset from the stack 19163 allocation pointer From Xiang Xiao. 19164 - IRQ Dispatch: Ensure vector never points to NULL since interrupt 19165 may happen before irq_initialize() From Xiang Xiao. 19166 - Work Queue: workqueues don't need set global data to zero since 19167 .bss is cleared automatically. Removing this unnecessary 19168 initialization also avoids the loss the work items queued before 19169 initialization. From ligd. 19170 - Work Queue: Remove work queue polling delay to simplify the code 19171 logic and save the power. From xuanlin. 19172 - syslog: Fix syslog crash on 64bit simulation. From anchao. 19173 - Pipes: Write to a pipe when there are no readers from the pipe 19174 should return -EPIPE. From ligd. 19175 - System Calls: Fix 6th parameter type of posix_spawnp in 19176 syscall.csv From Masayuki Ishikawa. 19177 - System Calls: Remove unused SYS_nnetsocket from syscall.h. Because 19178 SYS_nnetsocket is not implemented so far, it should be removed so 19179 that SYS_prctl can work correctly. From Masayuki Ishikawa. 19180 - Binary Loader: Refactor binfmt_exec.c. This change also fixes an 19181 argv issue for CONFIG_SCHED_ONEXIT=n or CONFIG_SCHED_HAVE_PARENT=n 19182 From Masayuki Ishikawa. 19183 - Binary Loader: Re-architect the way that loadable ELF or NXFLAT 19184 modules are unloaded. Memory resources must be recovered when the 19185 task loaded into memory exits. The original implementation used 19186 the death-of-child SIGCHLD signal to perform the unload. There are 19187 several problems with this: It is overly complex, it requires that 19188 the parent task stay resident while the loaded task runs, and it 19189 has fatal logic flaws in the protected and kernel model builds 19190 because the user signal handler attempts to run in the kernel 19191 address space. This corrects the issue using a mindlessly simply 19192 BINFMT callback when the task exits. From Gregory Nutt. 19193 - ELF Binary Loader: Set priority level to default if parent has no 19194 priority. From anchao. 19195 19196 * File System/Block and MTD Drivers: 19197 19198 - Auto-mounter: Ignore return values from work_cancel(). From 19199 Gregory Nutt. 19200 - SmartFS: Fixed filesystem corruption when writing to small file 19201 after open(... O_APPEND). From Dmitriy Linikov. 19202 - SmartFS stat(): A previous change added support for checking if a 19203 descriptor is a socket in fstat().' but it changed sys/stat.h in 19204 way that breaks smartfs file-type stat flags. CROMFS is similarly 19205 broken, as tools/gencromfs.c was not updated to match the 19206 sys/stat.h changes. This commit fixes both issues. It probably is 19207 not a good idea to use NuttX sys/stat.h bit-field values directly 19208 in stored structure of filesystem. From Jussi Kivilinna. 19209 - HostFS: Update duplicated definitions in HOSTFS that must match 19210 NuttX values. From ligd. 19211 - HostFS: Ensure f_type is equal to HOSTFS_MAGIC. From Xiang Xiao. 19212 - ROMFS: Make romfs_devread32 more portable From anchao. 19213 - TmpFS: Correct logic in tmpfs_ioctl() that extracts the priv state 19214 structure from the file system structures. It was not getting the 19215 right value and causing mmap() to fail. Noted by Jesse. From 19216 Gregory Nutt. 19217 - ProcFS network statistics: Was not handling the output correct for 19218 the case of an IEEE 802.11 device. From Gregory Nutt. 19219 - ProcFS IRQs: Fix occasional computation error when fracpart >= 19220 1000 From Xiang Xiao. 19221 19222 * Networking/Network Drivers: 19223 19224 - TAP/TUN: Fixed custom tun devname formatting. From Dmitriy Linikov. 19225 - Network Drivers: This change attempts remove some long standard 19226 confusion in naming and some actual problems that result from the 19227 naming confusion. The basic problem is the standard MTU does not 19228 include the size of the Ethernet header. For clarity, I changed 19229 the naming of most things called MTU to PKTSIZE. For example, 19230 CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE. This makes the 19231 user interface a little hostile. People think of an MTU of 1500 19232 bytes, but the corresponding packet is really 1514 bytes (including 19233 the 14 byte Ethernet header). A more friendly solution would 19234 configure the MTU (as before), but then derive the packet buffer 19235 size by adding the MAC header length. Instead, we define the 19236 packet buffer size then derive the MTU. 19237 The MTU is not common currency in networking. On the wire, the 19238 only real issue is the MSS which is derived from MTU by subtracting 19239 the IP header and TCP header sizes (for the case of TCP). Now it 19240 is derived for the PKTSIZE by subtracting the IP header, the TCP 19241 header, and the MAC header sizes. So we should be all good and 19242 without the recurring 14 byte error in MTU's and MSS's. From 19243 Gregory Nutt. 19244 - netdev: Fix.. Too many calls to net_unlock() From Gregory Nutt. 19245 - IPv6: There are many different checks for IPv6 multicast 19246 addresses. Most of the checks are different. RFC 3513 clearly 19247 specifies how to detect an IPv6 multicast address: they should 19248 begin with 0xffxx. I did not change some of the checks in 19249 ipv6_input.c, however. In that file, the comments indicate that 19250 the code should only pick of certain multicast address that begin 19251 with 0xff02. From Gregory Nutt. 19252 - ARP: Fix some backward logic in an if condition. From Gregory 19253 Nutt. 19254 - TCP Re-assembly: Rename CONFIG_TCP_REASSEMBLY to 19255 CONFIG_IPv4_REASSEMBLY. Add some fixes to get a clean compile with 19256 CONFIG_IPv4_REASSEMBLY enabled. There are several problems with 19257 the current implementation: It is untested (and depends on 19258 CONFIG_EXPERMIMENTAL). It uses some Ethernet specific definitions 19259 (and depends on CONFIG_NET_ETHERNET). There is only a single 19260 reassembly buffer. The last two issues prevent use of this feature 19261 in any context where IPv4 packets may be reassembled for multiple 19262 network devices concurrently). From Gregory Nutt. 19263 - TCP: Set the default TCP MSS to the value required by RFC 879 and 19264 never change it under any circumstance unless the remote host 19265 requests a larger MSS via an option the TCP header. From Gregory 19266 Nutt. 19267 - TCP: Fix a deadlock condition that can occur when (1) all network 19268 logic runs on a single work queue, (1) TCP write buffering is 19269 enabled, and (2) we run out of IOBs. In this case, the TCP write 19270 buffering logic was blocking on iob_alloc() with the network 19271 locked. Since the network was locked, the device driver polls that 19272 would provide take the write buffer data and release the IOBs could 19273 not execute. This fixes the problem by unlocking the network lock 19274 while waiting for the IOBs. From Gregory Nutt. 19275 - TCP: Remove g_netstats.tcp.syndrop++ from tcp_data_event() From 19276 Masayuki Ishikawa. 19277 - TCP Monitor: Fix net unlock issue when tcp close. This bug could 19278 leave the net locked. From zhangyuan7. 19279 - UDP: When sending a broadcast (or multicast) packet do not attempt 19280 to look up the device by the destination IP address. Rather, use 19281 the locally bound address for these cases to select the correct 19282 network device. From Gregory Nutt. 19283 - UDP: Restore some legacy behavior that was lost with the 19284 implementation of CONFIG_NET_UDP_BINDTODEVICE: If no device has a 19285 local address when the broadcast packet is sent and the UDP socket 19286 is not bound to a device, there select some arbitrary device. This 19287 is certainly lunacy in the case where there are multiple network 19288 devices registered because the wrong device will probably be 19289 returned. It works find, however, for the legacy case where only a 19290 single network device is registered. From Gregory Nutt. 19291 - UDP: Fix for network byte-order issue when checking if an address 19292 is a multicast address. From Jake Choy. 19293 - USRSOCK: Correct of semaphore usage issues. From Gregory Nutt. 19294 - USRSOCK: Fix re-definitions of struct iovec. From ligd. 19295 - ICMP/ICMPv6 Connection: Change the type of id in 19296 icmpv[6]_findconn to uint16_t From Xiang Xiao. 19297 - ICMP/ICMPv6: Fix failure to poll ICMP socket issue. From 19298 dongjianli. 19299 19300 * Wireless/Wireless Drivers: 19301 19302 - XBee: Fixes issue with timeouts. Timeouts were in ticks but 19303 should have been in ms. This caused false triggers of timeout 19304 causing redundant packets, etc. From Anthony Merlino. 19305 - BCM43xx: Add missing logic to the BCM43xx IEEE 802.11 driver to 19306 poll for more Tx data after the last transfer completes. From 19307 Gregory Nutt. 19308 - BCM43xx: Bring in some fixes from the 'Haywire' branch. From 19309 Ramtin Amin. 19310 19311 * Common Drivers: 19312 19313 - Audio: Fix compile error in i2schar.c (CONFIG_DEBUG_ASSERTIONS=y) 19314 From Masayuki Ishikawa. 19315 - Audio I2S: Fix bad NULL pointer check From Juha Niskanen. 19316 - Input: Fixed FT5x06 driver to correctly close (previously it 19317 unregistered interrupt handler during close). From Marcin Wyrwas. 19318 - MMC/SD: Fix an error that was causing SDIO multiple block 19319 transfers from achieving full performance. From Bob Feretich. 19320 - Sensors: Increases SPI frequency in MAX6675 from 400Khz to 4MHz. 19321 From Alan Carvalho de Assis. 19322 - Sensors: Remove comment references to touchscreens from ADXL345 19323 driver. From Russ Webber. 19324 - Serial: Don't overwrite nwritten unconditionally on UART write 19325 failure. From Xiang Xiao. 19326 - Serial DMA: Move head/tail pointer reset to uart_recvchars_dma 19327 since dma may be still transferring in the background. From Xiang 19328 Xiao. 19329 - Serial DMA: In DMA mode, the use of uart_disablexinit() is 19330 insufficient to protect a critical section. 19331 enter/leave_critical_section() must be used in those cases if 19332 CONFIG_SERIAL_DMA=y From Xiang Xiao. 19333 - Serial DMA: Fix typo error in uart_recvchars_dma() From Xiang Xiao. 19334 - 16550 UART: u16550_txempty() should check UART_LSR_TEMT to avoid 19335 some data left in the transmit FIFO From Xiang Xiao. 19336 19337 * ARMv7-A: 19338 19339 - ARMv7-A (and i.MX6): Add support for per-CPU IRQ and FIQ interrupt 19340 stacks (bugfix). Add support so that up_assert will print the 19341 correct interrupt stack on an assertion (FIQ stack is still not 19342 printed). From Gregory Nutt. 19343 19344 * ARMv7-R: 19345 19346 - ARMv7-R: Fix some wrong configuration of program status 19347 register. PSR_E_BIT bit should be set for big endian system. 19348 PSR_A_BIT bis is set automatically as arm cortex-r4 reference 19349 manual 3.7.4. So we don't need to set this bit. From EunBong Song. 19350 - ARMv7-R: Fix some wrong MPU register definition. Change 19351 MPU_RBAR_ADDR_MASK and MPU_RACR_TEX_SHIFT mask as arm cortex-r4 19352 reference manual. Region Base Address Register 0-4 bits are 19353 reserved. MPU Region Access control register type 3-5 bits. From 19354 EunBong Song. 19355 19356 * ARMv7-M: 19357 19358 - ARMv7-M, Cortex F7: Add a configuration to enable workaround for 19359 r0p1 Errata 837070: Increasing priority using write to BASEPRI does 19360 not take effect immediately. This update is required to be 19361 serialized to the instruction stream meaning that after this update 19362 completes, it takes effect immediately and no exceptions of lower 19363 priority than the new boosted priority can pre-empt execution. 19364 Because of this erratum, the priority boosting does not take place 19365 immediately, allowing the instruction after the MSR to be 19366 interrupted by an exception of lower priority than the new boosted 19367 priority. This effect is only limited to the next instruction. 19368 Subsequent instructions are guaranteed to see the new boosted 19369 priority. This was raised in Bitbucket issue 113 from Vadzim 19370 Dambrouski. From Gregory Nutt. 19371 - ARMv7-M: MPU: mpu_log2regionceil needs take into account the 19372 offset too From Xiang Xiao. 19373 - ARMv7-M MPU: The prototype of mpu_log2regionfloor() changed; an 19374 additional parameter was added. However, none of the calls to 19375 mpu_log2regionfloor() were updated to pass the new, additional 19376 parameter. From Gregory Nutt. 19377 19378 * Infineon XMC4xxx Drivers: 19379 19380 - XMC4 SPI: XMC4 SPI was working only for the first transfer From 19381 Alan Carvalho de Assis. 19382 19383 * Microchip/Atmel SAMv7 Drivers: 19384 19385 - SAMv7 MCAN: Correct an error in the BUS_OFF reporting. In case of 19386 BUS_OFF the old implementation was leading to a package storm. Now 19387 it reports the error condition BUS_OFF only once. From Frank 19388 Benkert. 19389 19390 * NXP/Freescale LPC43xx Drivers: 19391 19392 - LPC43xx CAN: Fix lpc43 CAN configuration. Configuration settings 19393 were used and documented in README.txt files, but never in any 19394 Kconfig file. From Gregory Nutt. 19395 - LPC43xx: Make WWDT usable again. LPC43xx WWDT driver was not 19396 updated when irq_dispatch grew an argument parameter. Also fixes 19397 two typos and a naming inconsistency (WWDT vs. WWDG). From Jakob 19398 Haufe. 19399 19400 * NXP/Freescale Kinetis Drivers: 19401 19402 - kinetis: USB0 fix interrupt storm on error. The ERROR bit of 19403 USBx_ISTAT needed to be cleared once an error occurs. From David 19404 Sidrane. 19405 - Kinetis: SDHC fix SDIO driver so that DMA works. There were 2 19406 problems. The first was that the interrupt did test DINT and raise 19407 a completion events. But since DINT is just an indication of DMA 19408 completion, TC is a valid way to determine that the transfer is 19409 complete. The second problem is that Software Reset For DAT Line 19410 SDHC_SYSCTL[RSTD] clears the bits 24-0 in SDHC_PROTO this looses 19411 the wide bus setting DTW From David Sidrane. 19412 - Kinetis: (1) PIT add Liftime and Chaining, (2) flexcan fix 19413 duplicate line and ordering, (3) kinetis_lowput.c LPUART data 19414 format with parity fix. The 9-bit data mode is typically used with 19415 parity to allow eight bits of data plus the parity, (4) lowputc 19416 LPUART_BAUD_INIT has to be defined. Build fails with test case 19417 enable LPUART0 and make UART1 console. If HAVE_LPUART_DEVICE is 19418 defined then LPUART_BAUD_INIT has to be defined even if the LPUART 19419 is not the console From David Sidrane. 19420 - Kinetis: I2C ensure timeout on bus error. The code had a dead 19421 wait on I2C_S_BUSY. Noise on the bus would cause the driver to 19422 hang. Add timeout on invalid states of I2C_S_BUSY to allow the 19423 upper layers do deal with restart or abort. From David Sidrane. 19424 19425 * NXP i.MXRT Drivers: 19426 19427 - i.MXRT Ethernet: I finally got the Ethernet CRC32 to work properly 19428 after the FAE pointed me in the right direction: (1) Added CRC32 19429 functions for multicast address filtering, (2) Do not reset PHY 19430 settings when doing an ifup, (2) Use chip's unique id as the device 19431 MAC, and (4) Enable discard enet frames with errors at PHY layer. 19432 From Jake Choy. 19433 19434 * On Semi LC823450 Boards: 19435 19436 - LC823450-XGEVK: Fix parallel build on lc823450-xgevk. This change 19437 fixes an archive file (*.a) corruption by locking $(TOPDIR). 19438 Please note that locking the current directory is insufficient 19439 because some archive files such as libapps.a are specified with 19440 absolute path. From Masayuki Ishikawa. 19441 - LC823450-XGEVK: Change IOB related params for rndis. Since TCP 19442 flow control scheme was changed, HTTP audio streaming has not been 19443 working. These IOB params are not optimized but HTTP audio 19444 streaming now works. From Masayuki Ishikawa. 19445 19446 * STMicro STM32: 19447 19448 - STM32 F7: Fix compile error caused by intentional use of fall 19449 through From Daniel Agar. 19450 19451 * STMicro STM32 Drivers: 19452 19453 - STM32 F1-F4: Port Bob Feritich's change to STM32 F2 and F4 which 19454 appear to have identical SD support and I/O compensation 19455 requirements. 19456 - STM32 F1-F4, STM32 F7, and STM32 L4: The STM32 RTC driver was 19457 being selected by the global CONFIG_RTC option. That is in 19458 correct. For example, if you want to disabled the STM32 RTC and 19459 use an external RTC you cannot because the external RTC also 19460 depends on the global CONFIG_RTC. The solution is to add a new 19461 CONFIG_STM32xx_RTC configuration option the permits to you select 19462 or deselect the STM32 RTC but still be able to selecte the external 19463 RTC. From Gregory Nutt. 19464 - STM32 F3 I2C: Fix compile error with I2C reset. From Juha 19465 Niskanen. 19466 - STM32 F7 Serial: Fix ioctl TIOCSSINGLEWIRE The TRM notes that UE 19467 must be disabled in order to write HDSEL in USART_CR3. This was not 19468 being done, so calls to TIOCSSINGLEWIRE were silently failing. 19469 This change checks the state of UE in USART_CR1, clears the UE bit 19470 before writing HDSEL, then re-enables it if neccesary. From Kurt 19471 Kiefer. 19472 - STM32 F7 DMA: DMA macros did not account for the increase from 8 19473 to 16 DMA channels. From Gregory Nutt. 19474 - STM32 F7 I2C: I2C reset Configure I2C pins as GPIO output. Pins 19475 were reset to inputs in the deinit(). This resets them to outputs. 19476 From David Sidrane. 19477 - STM32 F7: All of the SDMMC pins were set to 50 MHz, but not the 19478 clock. This sets the clock to 50 MHz also. This combined with 19479 turning on I/O compensation makes intermittent failures go away. 19480 From Bob Feritich. 19481 - STM32 F7: Port Bob Feritich's change to SDMMC2 and to all other 19482 STM32 F7 architectures. Also add a configuration option to 19483 automatically enable I/O compensation. From Gregory Nutt. 19484 - STM32 F7 SDMMC: Fix data timeout errors with multi-block 19485 transfers. From Bob Feretich. 19486 - STM32 L4: Corrects some mistakes in pin definitions for the 19487 STM32 L4 family. According to datasheet of STM32L496xx, STM32L475xx 19488 and STM32L443XX the AF2 of PE14 is TIM1_BKIN2 not TIM2_BKIN. From 19489 Daniel Pereira Carvalho. 19490 - STM32 L4: Avoid using redundant CONFIG_STM32L4_STM32L4X2. This is 19491 almost always same as CONFIG_STM32L4_STM32L4X3. Avoid duplication 19492 to reduce macro clutter. This patch limits 19493 CONFIG_STM32L4_STM32L4X2 usage to dependency tracking and pinmap. 19494 Also enable ADC for CONFIG_STM32L4_STM32L4X5 (untested, but same 19495 RM). From Juha Niskanen. 19496 - STM32 H7 Serial: don't include stm32_dma.h From raiden00pl. 19497 19498 * STMicro STM32 Boards: 19499 19500 - STM32F4-Discovery: Fix pca9635pw LED driver compilation on 19501 STM32F4-Discovery. From Alan Carvalho de Assis. 19502 - STM32F4-Discovery: Krassimir Cheshmedzhiev claims that sys/types.h 19503 needs to be included in the RGB LED file to avoid undeclared 'OK' 19504 From Gregory Nutt. 19505 - STM32F4-Discovery: Missing EXTERN(_vectors) in linker script. 19506 From Gregory Nutt. 19507 - Nucleo-L422KC: Fix RAM size; STM31L4x2xx has only 64Kb of RAM. 19508 Remove references to I2C and SDIO: There is no I2C2 or SDIO on the 19509 STM32F4x2xx. From Daniel P. Carvalho. 19510 - Nucleo-L422KC: Fix stm32_userleds. After change LD2 to LD3 in 19511 board.h stm32_userleds.c was broken. From Daniel P. Carvalho. 19512 - Nucleo-L422KC: Fix TIMx clock configuration. Also removes 19513 definitions related to timers not available in the STM32L432KC. 19514 From Daniel Pereira Carvalho. 19515 - Nucleo-L452RE: Fix TIMx clock configuration. This is cloned from 19516 similar change to the Nucleo-L422KC. Also fixes DAC build 19517 failure. From Juha Niskanen. 19518 - B-L475E-IOT01A: Fix copy paste errors in names: 19519 stm32_bringup->stm32l4_bringup. Noted by Freemans Goden. From 19520 Gregory Nutt. 19521 - STM32VL-Discovery: Changed the status LED to be the green one as 19522 mentioned in the README file. Removed the global array for buttons 19523 and replace it with the only button. Improve defconfig for the nsh 19524 configuration. From Ouss4. 19525 19526 * C Library/Header Files: 19527 19528 - libc audio: Call nxsem_destroy in apb_free. From Xiang Xiao. 19529 - libc netdb: The 'port' argument to the static alloc_ai() function 19530 is always in network byte order. However, that static function was 19531 still calling HTONS() on the port, incorrectly converting it back 19532 to host byte order. From Gregory Nutt. 19533 - libc netdb: Fix a link error in lib_gethostbynamer.c with protected 19534 build. NOTE: g_lo_ipv4addr also exists in 19535 net/loopback/lo_globals.c which can be linked with kernel build 19536 only. From Masayuki Ishikawa. 19537 - libc unistd : Fix backward conditional logic in Kconfig. From 19538 Gregory Nutt. 19539 - include/nuttx/compiler.h: Fix warning: __cplusplus is not defined. 19540 Some gcc derived compiler do not define __cplusplus From Xiang 19541 Xiao. 19542 - include/nuttx/fs/binfs.h: Fix warning: Type defaults to 'int' in 19543 declaration of 'mountpt_operations' From Xiang Xiao. 19544 - include/nuttx/net/ethernet.h: Remove CONFIG_NET_ETHERNET guard 19545 From Xiang Xiao. 19546 - include/nuttx/semaphore.h: don't include nuttx/fs/fs.h. (1) Avoid 19547 nested loops if CONFIG_SIG_EVTHREAD enabled, (2) semaphore.h 19548 doesn't depends on fs.h. From Gregory Nutt. 19549 - include/crc64.h: Fix warning: integer constant is too large for 19550 its type From Xiang Xiao. 19551 - include/limits.h and include/sys/types.h: Fix warning about 19552 'SIZE_MAX' redefined. include/nuttx/usb/audio.h: Fix warnings due 19553 to '-' used whete '_' intended. From Xiang Xiao. 19554 - include/spawn.h: Fix posix_spawnattr_destroy warning: 'the 19555 address of attr will always evaluate as true' From Xiang Xiao. 19556 - include/sys/types: Move wint_t and wctype_t from wchar.h to 19557 types.h. This change is compatible as before since wchar.h 19558 include types.h indirectly. This fixes a compilation error with 19559 newlib's math.h: 'unknown type name wint_t' From Xiang Xiao. 19560 - apps/include/netutils/netlib.h: Eliminate a warning about 19561 AF_UNSPEC and AF_INET not defined. From Gregory Nutt. 19562 19563 * Build System: 19564 19565 - Build System: Fix parallel build in making context. This change 19566 avoids running $(MKSYSCALL) and .context in parallel and ensures 19567 that tools/mksyscall is built before it is actually used. From 19568 Masayuki Ishikawa. 19569 - Kconfig files: Fix several errors noted by Alex Denisov in 19570 Bitbucket issue 115. From Gregory Nutt. 19571 - apps Build System: Fix an error when building apps/ without 19572 nuttx/, using only the NuttX export package and assuming that the 19573 nuttx/ directory in not even present. In this case, the problem 19574 fixed where the apps/Make.defs file was selecting tools from the 19575 /tools directory which does not exist because TOPDIR=apps/import. 19576 Instead, for this build case, I have not thought of any option but 19577 to duplicate scripts as necessary in the apps/tools directory. 19578 Also added a top-level target to compile the symbol table. Misc 19579 fixes: quoting in scripts, some errors in script syntax. From 19580 Gregory Nutt. 19581 - apps/Application.mk: If a loadable module is generated the we 19582 need to add logic to remove the loadable module in the 'make 19583 clean' logic. From Gregory Nutt. 19584 19585 * Tools: 19586 19587 - nuttx/tools/Makefile.unix: Was not cleaning up export directory 19588 if it was left from a failed export. From Gregory Nutt. 19589 - apps/tools: Fix an error in mksymtab.sh From Masayuki Ishikawa. 19590 19591 * NSH Library: apps/nshlib: 19592 19593 - apps/nshlib: Fix 'while' and 'until' loop condition The loop 19594 condition logic was inverted: 'while true; do echo "test"; done' 19595 would exit immediately, while using 'until' would stay in the 19596 loop. This is the opposite of how it is supposed to work. The 19597 reason is that 'state' was set wrong because 'whilematch' is a 19598 bool. From Beat K�ng. 19599 - apps/nshlib: I was able to cause an assertion with some typos in 19600 testing the 'fi' command. Not an important thing, but this will 19601 protect against the assertion. From Gregory Nutt. 19602 - apps/nshlib: Increase the default configuration for the maximum 19603 number of command line arguments to 7 (CONFIG_NSH_MAXARGUMENTS). 19604 This is needed for 'mount' with the -o option. From Xiang Xiao. 19605 - apps/nshlib: Do not dereference NULL 'pstate' in nsh_console.c. 19606 From Juha Niskanen. 19607 19608 * Examples/Tests: apps/examples: 19609 19610 - apps/examples: Remove illegal calls into OS to initialize BINFMT 19611 support. This must be moved to the board initialization logic 19612 within the OS. From anchao. 19613 - apps/examples/nettest: Fix typo: NET_LOOPBACK -> 19614 CONFIG_NET_LOOPBACK nettest: Fix compilation error. Should enable 19615 NET_SETSOCKOPT for preventing compilation error. From EunBong Song. 19616 - apps/examples/ostest: Signal handling tests should use the same 19617 configurable stack size as used in other tests, not 19618 PTHREAD_STACK_DEFAULT. From Gregory Nutt. 19619 - apps/examples/ostest: Attempt to make the nested signal test 19620 compatible with the suspend/resume test. Some signals cannot be 19621 caught when the suspend/resume configuration is in place. From 19622 Gregory Nutt. 19623 - apps/examples/smps: Fixes in some printf and in Kconfig. From 19624 Mateusz Szafoni. 19625 19626 * System Utilities: apps/system: 19627 19628 - apps/system/cu: (1) Protect from possible re-definition of signal 19629 values, (2) Fix CU ctrl-C hand when remote core hang. From ligd. 19630 - apps/system/i2c: Fix a backward comparison in i2c_main.c. Noted 19631 by Jakob Haufe. From Gregory Nutt. 19632 - apps/system/nsh: Fix compile errors with 19633 CONFIG_EXAMPLES_NSH_SYMTAB=y. From Masayuki Ishikawa. 19634 - apps/system/ping and ping6: Send ID and seqno in network byte 19635 order. From Xiang Xiao. 19636 - apps/system/ping and ping6: Change dependency in ping and ping6 19637 Kconfig. These may be implemented in users sockets and, hence, 19638 may need to be available even if ICMP and ICMPv6 sockets are not 19639 support. From Xiang Xiao. 19640 - apps/system/system: Add 'const' to make function prototype 19641 compatible with OpenGroup.org requirement From Xiang Xiao. 19642 - apps/system/zmodem: Fix error "sz_main.o: No such file or 19643 directory" From Xiang Xiao. 19644 19645 * Network Utilities: apps/netutils: 19646 19647 - apps/netutils/ftpc: Fix handling of url-encoded strings From 19648 Dmitriy Linikov. 19649 - apps/netutils/ping: Remove unsupported ping. netutils/ping is not 19650 supported anymore. It's better to remove this folder for 19651 preventing confusing. ping is supported by system/ping. From 19652 EunBong Song. 19653 19654 * Wireless Utilities: apps/wireless: 19655 19656 - apps/wireless/wapi: Remove dependency on CONFIG_EXPERIMENTAL from 19657 Kconfig From Gregory Nutt. 19658 19659 * GPS Utilities: apps/gpsutils: 19660 19661 - apps/gpsutils/minmea: Include wchar.h in minmea.c file to fix 19662 wint_t error From Alan Carvalho de Assis. 19663 19664 * Interpreters: apps/interpreters: 19665 19666 - Remove apps/interpreters/micropthon. There are several reasons 19667 for this. (1) the current version 1.3.8 is very old and no one is 19668 supporting it. (2) the port only includes the core micropython 19669 logic and none of the Python libraries. As such it is useless in 19670 any real application. (3) There have recently been compile 19671 failures reported. It looks like this is due to changes in newlib 19672 based toolchains that now bring in incompatible newlib header 19673 files. See issue 104 at 19674 https://bitbucket.org/nuttx/nuttx/issues/104/build-micropython-138-error. 19675 With no one dedicated to the support of micropython, it can no 19676 longer be carried in the NuttX apps/ repository. From Gregory Nutt. 19677 19678NuttX-7.27 Release Notes 19679------------------------ 19680 19681The 127th release of NuttX, Version 7.27, was made on November 14, 2018, 19682and is available for download from the Bitbucket.org website. Note 19683that release consists of two tarballs: nuttx-7.27.tar.gz and 19684apps-7.27.tar.gz. These are available from: 19685 19686 https://bitbucket.org/nuttx/nuttx/downloads 19687 https://bitbucket.org/nuttx/apps/downloads 19688 19689Both may be needed (see the top-level nuttx/README.txt file for build 19690information). 19691 19692Additional new features and extended functionality: 19693 19694 * Core OS: 19695 19696 - Assertions: Add 'BOARD_ASSERT_RESET_VALUE' in config/Kconfig and 19697 replace reboot status '0' to 'CONFIG_BOARD_ASSERT_RESET_VALUE'. From 19698 Gregory Nutt. 19699 - Assertions: up_registerdump capture the general register if not yet 19700 saved and up_saveusercontext is implemented, the register dump is very 19701 useful to find the cause of failure. From Xiang Xiao. 19702 - Assertions: up_stackdump() dump the full stack if stack overflow the 19703 stack info is very useful to find the backtrace From Xiang Xiao. 19704 - binfmt/ and libs/libc: Make exepath_*() more common: Move 19705 exepath_*() related code to libc/misc, rename exepath_ to envpath_, 19706 and rename BINFMT_EXEPATH to LIB_ENVPATH. From nchao. 19707 - CLOCK: Support CLOCK_MONOTONIC in clock_getres.c. From Xiang Xiao. 19708 - Clock Timekeeping: Use clock_basetime() to initialize 19709 g_clock_wall_time to get the best initial RTC value and initialize 19710 g_clock_last_counter too since the hardware may not start counting 19711 from zero. From Xiang Xiao. 19712 - exit(): Add SCHED_EXIT_KILL_CHILDREN option to kill all child threads 19713 when the main thread of a task exits. From nchao. 19714 - IOBs: Add an IOB notifier that will notify any registered threads 19715 that want to known when an IOB has been freed. This is basically just 19716 a wrapper around the generic notifier. Includes a divider that can be 19717 used to reduce the rate of IOB notifications. From Gregory Nutt. 19718 - Memory Manager: In mm_free(), add DEBUGASSERT()'s to catch memory 19719 corruption early. From Petteri Aimonen. 19720 - Memory Manager: Add debug option CONFG_MM_FILL_ALLOCATIONS to fill 19721 all mallocs() with recognizable value. From Petteri Aimonen. 19722 - sched/signal and syscall/: Add support for pselect() and ppoll() 19723 functions From dongjianli. 19724 - Task Groups: group_foreachchild() now iterates in reverse order since 19725 the callback (e.g. group_killchildren) may remove the tcb from list. 19726 From zhangyuan7. 19727 - WDOG Timer: Improve accuracy of wd_gettime() in tickless mode From 19728 ligd. 19729 - Work Queues: Add a generic notification facility that runs on a work 19730 queue. The notication facility can notify a group of subscribers to 19731 an event via callbacks. This API is for use within the OS only. From 19732 Gregory Nutt. 19733 19734 * File Systems/Block and MTD Drivers 19735 19736 - FAT: Add CONFIG_FAT_LFN_ALIAS_HASH to speed up creating long 19737 filenames. Long filenames on FAT file systems have associated 8.3 19738 character alias short filenames. The traditional form of these is 19739 FILENA~1.EXT with a running count of the number of similar names. 19740 However creating this unique count can take several seconds if there 19741 are many similarly named files in the directory. Enabling 19742 FAT_LFN_ALIAS_HASH uses an alternative format of FI0123~1.TXT where 19743 the four digits are a hash of the original filename. This method is 19744 similar to what is used by Windows 2000 and later. From Petteri 19745 Aimonen. 19746 - FAT: Add CONFIG_FAT_LFN_ALIAS_TRAILCHARS alternative format for 8.3 19747 filenames. Traditional format for long filename 8.3 aliases takes 19748 first 6 characters of long filename. If this option is set to N > 0, 19749 NuttX will instead take first 6-N and last N characters to form the 19750 short name. This is useful for filenames like "datafile12.txt" where 19751 the first characters would always remain the same. From Petteri 19752 Aimonen. 19753 - FAT: if block driver wait seems to be a long one, give time for other 19754 threads to run. From Petteri Aimonen. 19755 - file_open(): Add file_open() implementation with some fully-function, 19756 interim, placeholder logic. Change occurrences of open() followed by 19757 file_detach() in the OS to file_open(). From Gregory Nutt. 19758 - MX25LF25635F: Add support to Macronix MX25LF25635F serial NOR flash 19759 From David Sidrane. 19760 - nx_open(): Add nx_open() which is the same as open() except that it 19761 does not create a cancellation point nor does it modify the errno 19762 variable. Change most other, non-controversial calls to open() to 19763 nx_open(). From Gregory Nutt. 19764 - file_ioctl(): Replace calls to ioctl() in the OS to file_ioctl(). 19765 From Gregory Nutt. 19766 - mount: Add mount() support for file systems that require MTD drivers 19767 (vs. block drivers). From Gregory Nutt. 19768 - mount: Add support for mounting a file system with either a block or 19769 an MTD driver. From Xiang Xiao. 19770 - MTD FTL: Support BIOC_FLUSH ioctl From Xiang Xiao. 19771 - MTD FTL: Make READAHEAD and WRITEBUFFER work independently of each 19772 other. There have cases we use writebuffer but not readbuffer, so the 19773 write buffer must be flushed before read. Let rwb driver do it. From 19774 zhuyanlin. 19775 - MTD FTL: Allocate eblock only when it's really needed From Xiang Xiao. 19776 - MTD FTL: Add support support unlink operation to avoid the memory 19777 leak. From Xiang Xiao. 19778 - MTD Partition: Add register_mtdpartition() for MTD partition From 19779 Xiang Xiao. 19780 - MTD Partition: Remove the hard code partition name length From Xiang 19781 Xiao. 19782 - MTD Proxy: Make MTD device accessible via a character driver proxy 19783 like block devices From Xiang Xiao. 19784 - ProcFS: Change output of the ProcFS 'env' file so that it looks more 19785 like output from the 'env' command. From Gregory Nutt. 19786 - ProcFS: Add support to provide MLD statistics at /proc/net/mld. From 19787 Gregory Nutt. 19788 - ProcFS: Remove MTD ProcFS and mtd_procfsoperations() since we can now 19789 get the same information from inode From Xiang Xiao. 19790 - ProcFS: Add /proc/version support to get version info From iuhaitao. 19791 - ProcFS: Add support for named MTD drivers in the pseudo file system. 19792 This will, eventually, allow us to mount file systems that need MTD 19793 drivers without having to fake an intervening block driver. 19794 - R/W Buffer: Don't queue work to flush write buffer if 19795 CONFIG_DRVR_WRDELAY == 0 From Xiang Xiao. 19796 - R/W Buffer: Improve the rwb_read/write overlap performance From 19797 zhuyanlin. 19798 - SIM HOSTFS: Support S_IFSOCK, DT_LNK, O_DIRECT and O_SYNC From Xiang 19799 Xiao. 19800 - SPIFFS: Brings in a NuttX port of version 0.3.7 of Peter Anderson's 19801 SPIFFS flash file system into NuttX. From Gregory Nutt. 19802 19803 * Networking/Network Drivers: 19804 19805 - Network Configuration Add new configuration CONFIG_NET_MCASTGROUP. 19806 This option is selected automatically if either CONFIG_NET_IGMP or 19807 CONFIG_NET_MLD are selected. Most conditional logic based on 19808 CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP. 19809 From Gregory Nutt. 19810 - Network Device: Add notification logic for the case where the network 19811 goes down. From Gregory Nutt. 19812 - Network Device: Rename netdev_dev_lladdrsize() to netdev_lladdrsize() 19813 and move the prototype to include/nuttx/nex/netdev.h, giving is global 19814 scope within the OS. From Xiang Xiao. 19815 - ARP: Redesign ARP table aging to simplify the net initialization 19816 From Xiang Xiao. 19817 - ARP: Check ifname match before sending packet. From Xiang Xiao. 19818 - ARP and ICMPv6: Double the delay time on each iteration for ARP/ICMP 19819 to fight work jitter better. From Xiang Xiao. 19820 - ICMP/ICMPv6: Add NET_ICMP[v6]_NO_STACK for usrsock case From Xiang 19821 Xiao. 19822 - ICMPv6: Encapsulate the link scope address generation into 19823 icmpv6_linkipaddr() From Xiang Xiao. 19824 - ICMPv6: Remove the coupling between ICMPv6 and Ethernet by moving all 19825 Ethernet stuff to neighbor_ethernet_out.c and make the mac address as 19826 first field. From Xiang Xiao. 19827 - ICMPv6 MLD: Implement Multicast Listener Discovery (MLD) protocol based 19828 on RFC 2710 and RFC 3810. From Gregory Nutt. 19829 - ICMPv6 MLD: Implement MLDv1 compatibility mode. From Gregory Nutt. 19830 - ICMPv6 MLD: Implement 'Other Querier Present Timer'. This timer is 19831 used to revert to Querier mode if there is no other querier on the 19832 network. From Gregory Nutt. 19833 - IGMP: Backport some MLD design improvements/fixes. From Gregory Nutt. 19834 - IPv4 setsockopt(): Add implementation for all IPv4 socket options that 19835 have implemented IOCTL command counterparts. From Gregory Nutt. 19836 - IPv4/6 Socket Options: Add framework to support IPv4 and IPv6 19837 protocol socket options (i.e., SOL_IP and SOL_IP6). Handling of these 19838 socket options was a necessary step on the way to ICMPv6 MLD support. 19839 From Gregory Nutt. 19840 - ICMPv6 Autoconfiguration: Don't take the network device down when 19841 reconfiguring only the IP address from within ICMPv6 logic. 19842 Recommended by Xiang Xiao in order to avoid the long delays of 19843 bringing some networks back up. Normally it is required that the 19844 network be in the "down" state when re-configuring the network 19845 interface. This is thought not to be a necessary here because: (1) 19846 The ICMPv6 logic here runs with the network locked so there can be no 19847 outgoing packets with bad source IP addresses from any asynchronous 19848 network activity using the device being reconfigured. And (2) incoming 19849 packets depend only upon the MAC filtering. Network drivers do not 19850 use the IP address; they filter incoming packets using only the MAC 19851 address which is not being changed here. From Gregory Nutt. 19852 - IPv6 Input: Add logic to skip over the variable number of IPv6 19853 extension headers that may be present between the IPv6 header and the 19854 transport layer header. The extension headers are simply ignored. 19855 This is necessary because with MLD, certain incoming messages may 19856 have, at a minimum, a Router Alert Hop-by-hop extension header. 19857 Additional changes to ICMPv6, TCP, and UDP input to handle the offset 19858 protocol headers. From Gregory Nutt. 19859 - IPv6 Neighbor: Simplify the neighbor table aging process From Xiang 19860 Xiao. 19861 - IPv6 Neighbor: Simplify neighbor_dumpentry() implementation From 19862 Xiang Xiao. 19863 - IPv6 Neighbor: neighbor_lookup() checks if the target IP belongs to 19864 one of the local network devices. From Xiang Xiao. 19865 - IPv6 Neighbor: Support neighbor_out() for multiple link layer at the 19866 same time From Xiang Xiao. 19867 - IPv6 setsockopt(): Implement the IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP 19868 socket options. From Gregory Nutt. 19869 - TCP: Extend the TCP notification logic logic so that it will report 19870 loss of connection events. From Gregory Nutt. 19871 - SLIP: Add IPv6 support and fix minor issue From Xiang Xiao. 19872 - TCP: Add TCP poll() logic to receive notifications when IOBs are 19873 freed. From Gregory Nutt. 19874 - TCP: In TCP backlog, add SOMAXCONN definition and implementation per 19875 OpenGroup.org. From zhangyuan7. 19876 - TCP/UDP: Extend send()/sendto() logic it also requires that at least 19877 one IOB is also available to be able to send. From Gregory Nutt. 19878 - TCP/UDP: Add notification logic when TCP or UDP read-ahead data is 19879 buffered. From Gregory Nutt. 19880 - TUN: Call ipv[4|6]_input dynamically by checking packet header and 19881 remove the code duplication From Xiang Xiao. 19882 19883 * Wireless/Wireless Drivers: 19884 19885 - Broadcom IEEE 802.11: Add capability for Broadcom chips to get 19886 firmware and CLM data from a mounted file system vs. in-memory data 19887 structures. From Ramtin Amin. 19888 - XBee IEEE 802.15.4: Add support for setting/getting tx power. From 19889 Anthony Merlino. 19890 19891 * Other Common Device Drivers: 19892 19893 - GPIO: Support multiple registrations of GPIO signal events. From 19894 Xiang Xiao. 19895 - INA226: Add INA226 device driver. From Daniel P. Carvalho. 19896 - MAX7219: Support all digits presented in the MAX7219 datasheet. From 19897 Alan Carvalho de Assis. 19898 - MLX90614: Add support for the Infrared Thermometer MLX90614 From 19899 Alan Carvalho de Assis. 19900 - RTC Driver: up_rtc_set_lowerhalf call clock_synchronize() for 19901 external RTC.

From Xiang Xiao. 19904 - SYSLOG: syslog_initialize initialize dev/syslog too and call syslog 19905 to add the prefix and timestamp. From Xiang Xiao. 19906 - USB Composite and DFU drivers: Add support for Microsoft OS 19907 descriptors. These Microsoft-only descriptors help in loading the 19908 correct driver on Windows. They are especially helpful to give libusb 19909 access to a custom device without having to manually configure/install 19910 WinUSB driver. With this change DFU interface works automatically on 19911 Windows 10 with dfu-util 0.9 and libusb 1.0.22. On Windows 7 it still 19912 appears to need driver installation. From Petteri Aimonen. 19913 - USB DFU Device: Add DFU Runtime driver for activating boot-loader 19914 through USB command. From Petteri Aimonen. 19915 - USB RNDIS Device: Account for CONFIG_NET_GUARDSIZE in allocation of 19916 packet buffer allocation: Make USB device parameters configurable. 19917 From Sakari Kapanen. 19918 - USB RNDIS Composite Device: Fix strid comparison.

From hhuysqt. 20013 20014 * Other Tools: 20015 20016 - tools/tesbuild.sh: No longer installs and builds the NxWidgets 20017 libraries. They are now a port of apps/. From Gregory Nutt. 20018 20019 * Libraries/Header Files: 20020 20021 - include/net and include/sys: Align the constant values with values in 20022 the Linux kernel which makes targeting the usrsock server to Linux 20023 kernel easier. From Xiang Xiao. 20024 - include/netdb.h Add NO_ADDRESS definition From zhangyuan7. 20025 - include/netinet/in.h: Adds definitions for IPPROTO_IPV6 socket 20026 options to netinet/in.h. Adds missing fields to sockaddr_in6. Adds 20027 struct ipv6-mreq. These changes all follow the opengroup standard for 20028 netinet/in.h From Anthony Merlino. 20029 - include/netinet/in.h: Add IPv4 SOL_IP socket options for symmetry 20030 with IPv6 definitions added in a previous commit. Remove some 20031 duplicate types from sys/sockio.h. From Gregory Nutt. 20032 - include/netinet/in.h: Add other definitions required by 20033 OpenGroup.org. From Gregory Nutt. 20034 - include/netinet/in.h: Add Linux IP_PKTINFO and IPV6_PKTINFO 20035 definitions. 20036 - include/nuttx/net/ipv6ext.h: Create header file with all of the 20037 definitions of IPv6 extension headers that I could find. From Gregory 20038 Nutt. 20039 - include/nuttx/net/mld.h: Add MLD header file based on RFC2710 and 20040 RFC3810. From Gregory Nutt. 20041 - include/sys/socket.h: With increased size of struct sockaddr_in6, the 20042 size of struct sockaddr_storage in include/sys/socket.h must also be 20043 increase so that it can contain the new, larger sockaddr_in6. From 20044 Gregory Nutt. 20045 20046 - libs/libc/misc: Add implementation of CRC8-CCITT. From Alan Carvalho 20047 de Assis. 20048 - libs/libc/modlib: Add per-module library symbol table support. From 20049 nchao. 20050 - libs/libc/net: Add basic implementation for recvmsg() and sendmsg() 20051 per OpenGroup.org specification. From ligd. 20052 - libs/libc/netdb: A few improvements to getaddrinfo: (1) Use the 20053 protocol and socktype hints in returned address, (2) Ignore AI_PASSIVE 20054 argument if hostname is not NULL From Anthony Merlino. 20055 - libs/libc/netdb: Make DNS receive timeout configurable. From ligd. 20056 - libs/libc/stdio: Eliminate recursive in conversion functions of 20057 lib_vsprintf(). From Xiang Xiao. 20058 - libs/libc/string: Add some new functions defined in POSIX.1-2017: 20059 stpncpy(), strsignal(), psignal(), psiginfo(). From Gregory Nutt. 20060 - libs/libc/string: Add memrchr() function From Xiang Xiao. 20061 - libs/libc/string: Make strerror() return the string "Success" for 20062 error = 0. From Petteri Aimonen. 20063 20064 * Build System: 20065 20066 - Makefile.unix/win: Remove deletion of Eclipse project files from make 20067 distclean target. From Gregory Nutt. 20068 - apps/Application.mk: Fix some build issues. (1) Unable to found 20069 target 'context' when CONFIG_NSH_BUILTIN_APPS disabled. (2) Unable to 20070 generate multiple programs. From Chao An. 20071 - apps/Directory.mk: Fix distclean targets. Makefiles were not 20072 removing generated Kconfig files. There was then no way to remove 20073 this Kconfig files without manually deleting them one at a time. From 20074 Gregory Nutt. 20075 20076 * NSH: apps/nshlib: 20077 20078 - apps/nshlib/, apps/examples/: Update to show newer file system 20079 object types returned by stat(). From Gregory Nutt. 20080 - apps/nshlib: Add support for the 'env' command. From Gregory 20081 Nutt. 20082 - apps/nshlib: Add support for NSH local variables if 20083 CONFIG_NSH_VARS are set. These are like environment variables but 20084 are local to NSH. The importance of this is that these variables 20085 are *not* inherited when NSH creates a new task. The new command 20086 'export' was added. In this case, the NSH variable will be promoted 20087 to an environment variable and will then be inherited by any tasks 20088 executed by NSH. From Gregory Nutt. 20089 - apps/nshlib: If CONFIG_NSH_VARS=y, the NSH 'set' command with no 20090 argument will list all of the local NSH variables. From Gregory 20091 Nutt. 20092 20093 * Examples/Tests: apps/examples: 20094 20095 - apps/examples/gpio: Align with GPIO driver update From wangyanjiong. 20096 - apps/examples/ina226: Added INA226 example From Daniel P. Carvalho. 20097 - apps/examples/mld: Add a test of MLD. Provides a mechanism for some 20098 low-level bring-up of MLD. From Gregory Nutt. 20099 - apps/examples/mlx90614: Add mlx90614 test example From Alan Carvalho 20100 de Assis. 20101 - apps/examples/mlx90614/: Include support to change device address on 20102 mlx90614 From Alan Carvalho de Assis. 20103 - apps/examples/fstest: Adapt the existing fstest example for SPIFFS: 20104 For SPIFFS, add garbage collection and file system integrity IOCTL 20105 calls. Call statfs() and show state of file system on each loop. Add 20106 logic to dump logic content of SPIFFS. Ignore EINTR errors while 20107 reading or writing. Add configuration option to customize stack 20108 size. Detect when the media is full and stop writing files. Report 20109 total file size. From Gregory Nutt. 20110 - apps/examples/tcpblaster: Add an option to use poll() to pace input 20111 or output. From Gregory Nutt. 20112 - apps/examples/tcpblaster: Select CONFIG_LIBC_FLOATINGPOINT 20113 automatically. Units in output are wrong: Not Kbps bus Kb/Sec. From 20114 Gregory Nutt. 20115 - apps/examples/udpblaster: Add option to use poll() on output (only). 20116 From Gregory Nutt. 20117 20118 * System Utilities: apps/system 20119 20120 - apps/system/ping and apps/system/ping6: Set optind to zero in the 20121 error case/. Move all ping preparation work into icmp_ping. Support 20122 -W <timeout> and -s <size> option. Decouple the output from ping 20123 logic. From Xiang Xiao. 20124 - apps/system/ping and pings and apps/netutils/ping: Extract icmp ping 20125 and icmpv6 ping6 logic from system/ to C-callable library in 20126 netutils/. From ligd. 20127 - apps/system/progmem: Remove this utility. It makes illegal direct 20128 calls into the OS. From Gregory Nutt. 20129 20130 * Network Utilities: apps/netutils: 20131 20132 - apps/netutils/netlib and apps/examples/igmp: Adapt to use the 20133 corrected, semi-standard version of struct ip_msfilter. From Gregory 20134 Nutt. 20135 - apps/netutils/chat and apps/examples/chat: 'constify' chat variables 20136 and parameters From Xiang Xiao. 20137 20138 * Wireless Utilities: apps/wireless: 20139 20140 - apps/wireless/ieee802154/i8sak: Properly shuts down event thread. 20141 From Anthony Merlino. 20142 - apps/wireless/ieee802154/i8sak: Fixes i8sak name. Accidentally renamed 20143 to i8ask in recent changes From Anthony Merlino. 20144 - apps/wireless/ieee802154/i8sak: Adds support for getting/setting 20145 transmit power. From Anthony Merlino. 20146 20147 * Graphic Utilities: apps/graphics: 20148 20149 - apps/graphics/NxWidgets: Move the NxWidgets repository into the apps/ 20150 repository. Remove old apps/NxWidgets directory. Move NxWidgets 20151 files into apps/graphics/NxWidgets. Integrate configuration/build 20152 system. Fix file paths in file headers. Remove some duplicate 20153 tools. Add new NxWidgets Unit Test configuration and build logic. 20154 From Gregory Nutt. 20155 - apps/graphics/NxWidgets: Add CNxString string + operator and 20156 ::format() function. Add CNumericEdit option to include unit name 20157 after the value. Make CNxWidget useWidgetStyle() public. From 20158 Petteri Aimonen. 20159 - apps/graphics/NxWidgets: Add CLabelGrid control for displaying text 20160 in grid format. From Petteri Aimonen. 20161 20162Bugfixes. Only the most critical bugfixes are listed here (see the 20163ChangeLog for the complete list of bugfixes and for additional, more 20164detailed bugfix information): 20165 20166 * Core OS: 20167 20168 - Clock: Remove g_monotonic_basetime and g_clock_monotonic_time since 20169 we don't need ensure monotonic time start from zero as state here: 20170 http://pubs.opengroup.org/onlinepubs/009696899/functions/clock_getres.html 20171 From Xiang Xiao. 20172 - Clock: Don't call up_timer_gettime in clock_gettime() and 20173 clock_systimer() to ensure the return value from them consistent with 20174 clock_systimespec From Xiang Xiao. 20175 - Clock Initialization: clock_inittime() needs to be done with 20176 CONFIG_SCHED_TICKLESS and clock_initialize should skip 20177 clock_inittime() for external RTC case since the RTC isn't ready yet. 20178 From Xiang Xiao. 20179 - IOBs: Work around some issues with the IOB throttle semaphore. It 20180 has some odd behaviors that can cause assertions in sem_post(). Also, 20181 it seems to get outside of its range occasionally. Need to REVISIT 20182 this. From Gregory Nutt. 20183 - IOBs: iob_navail() was returning the number of free IOB chain queue 20184 entries, not the number of free IOBs. Completely misnamed. From 20185 Gregory Nutt. 20186 - PM: Use the start time of state btime to calculate thrcnt; remove the 20187 loop whose count may be very big after the long idle From ligd. 20188 - PM Uninitialization: Fix pm_domain_s.stime un-initialize caused time 20189 error. From ligd. 20190 - sched_kfree() and sched_ufree(): This patch prevent heap corruption 20191 in a corner case where memory is freed while switching contexts. This 20192 change forces all de-allocations via sched_kfree() and sched_ufree() 20193 to be delayed. Eliminating the immediate de-allocation prevents the 20194 problem with the the re-entrant semaphore because the deallocation 20195 always occurs on the worker thread, never on the suspended task. From 20196 EunBong Song. 20197 - sigsuspend(): sigsuspend() shouldn't eat the pending signal but 20198 dispatch all instead From Xiang Xiao. 20199 - task_restart(): Was restarting tasks with all signals set in the 20200 sigprocmask set. Should have restarted with the sigprocmask cleared. 20201 Noted by Jeongchan Kim From Gregory Nutt. 20202 - unsetenv(): Fix and error in unsetenv() when un-setting the last of 20203 the environment variables. From Gregory Nutt. 20204 - waitpid(): Remove a bad error check. From Gregory Nutt. 20205 20206 * File System/Block and MTD Drivers: 20207 20208 - FAT: Fix file data corruption in fat_truncate(). From Petteri Aimonen. 20209 - Partitions: Try MTDIOC_GEOMETRY IOCTL before bops's geometry. 20210 From Xiang Xiao. 20211 - MTD Progmem: Change up_progmem_npages() to up_progmem_neraseblocks(). 20212 page is a unit for read/write operation. eraseblock is a unit for 20213 erase operation. up_progmem_npages() is a little bit confusing 20214 because it returns number of erase blocks in flash memory. This patch 20215 changes up_progmem_npages to up_progmem_neraseblocks. 20216 up_progmem_eraseblock erase a block. so it's better to return the 20217 erase block size than page size. From EunBong Song. 20218 - R/W Buffer: Fix a lock issue From Xiang Xiao. 20219 - SmartFS: Current sector should have a space for next entry size. If 20220 not, we should move to next sector. From EunBong Song. 20221 20222 * Networking/Network Drivers: 20223 20224 - 6LoWPAN: Fixes bug in uncompress_addr handling of odd postfix. This 20225 affected multicast compress/uncompress since it's the only logic that 20226 used an odd postfix. The odd byte needs to be handled first, not 20227 last. From Anthony Merlino. 20228 - ARP and ICMPv6: Don't call d_txavail directly since it may point to 20229 NULL From Xiang Xiao. 20230 - ICMPv6: icmpv6_neighbor() shouldn't use the out of scope 20231 variable(dripaddr) From Xiang Xiao. 20232 - IPv6 input: Fixes logic in ipv6_input to handle more than ff02::/16 20233 multicast addresses. Don't forward mcast packets if scope is not 20234 appropriate From Anthony Merlino. 20235 - IPv6 Input: Fix a logic error when the received IPv6 srcaddr is a 20236 multicast address. Exiting logic only supported UDP multicast. But 20237 MLD and certain other ICMPv6 packets also require acceptance of 20238 multicast packets. From Gregory Nutt. 20239 - TCP: In TPC recv window calculations, in order to receive data we 20240 must not only have IOBs available, but we must also have at least one 20241 IOB chain qentry available. Otherwise, we will advertise that we an 20242 buffer a lot of data when, in fact, we cannot. This is an 20243 experimental fix to a performance problem noted by Masayuki Ishikawa. 20244 From Gregory Nutt. 20245 - TCP: Fix compiler error and warning when CONFIG_NET_SENDFILE=y From 20246 Xiang Xiao. 20247 - TCP Input: Fix recovery when ackseq > unackseq. The comment near 20248 this line says "reset the number of outstanding, unacknowledged 20249 bytes". However, the code actually resets the whole TCP connection. 20250 It was changed to the current form in commit f034d84ea1f with no 20251 explanation of the intent. Recover the line to what it was before that 20252 commit. From Sakari Kapanen. 20253 - TCP Write Buffering: Fix buffer release handling on failed buffer 20254 allocation. Attempt to release write buffer on failed TCP write I/O 20255 buffer alloc and tryalloc failed to wrb->wb_iob assertion. From Harri 20256 Luhtala 20257 - TCP/UDP: In the POLLOUT poll logic, request an immediate Tx poll from 20258 the network device bound to the socket. From Gregory Nutt. 20259 - UDP: On a failure to find the destination device, fallback to 20260 netdev_default device if the device is not found, rather than 20261 arbitrary using the device at the head of the list of devices. From 20262 Xiang Xiao. 20263 - USRSOCK: Revert previous commit to re-allow combination of usrsock 20264 and NuttX TCP/IP stack. For example, in case device has Ethernet and 20265 mobile connectivity and NuttX TCP/IP stack is used when configured to 20266 use Ethernet connection and usrsock when configured to use modem 20267 (modem TCP/IP stack through usrsock). From Jussi Kivilinna. 20268 - USRSOCK accept(): Mark newconn ready before issue accept request to 20269 avoid the case that the request is discarded due to the socket being 20270 in the invalid state From Xiang Xiao. 20271 20272 * Wireless/Wireless Drivers: 20273 20274 - Broadcom 802.11 Driver: There were two functions that have a address 20275 issue. In bcmf_read_sbreg() and bcmf_write_sbreg(): 20276 SBSDIO_SB_OFT_ADDR_MASK should be used before map address space. 20277 Noted by Shao Li in Bitbucket issue #126. From Gregory Nutt. 20278 - Broadcom 802.11 Driver: Remove incorrect OR condition. Always true. 20279 Noted by Shao Li in Issue 127. From Gregory Nutt. 20280 - NRF24L01: Fix compilation errors. From Mateusz Szafoni. 20281 20282 * Other Common Drivers: 20283 20284 - ALARM Upper Half: Fix alarm ISR error when no CONFIG_SCHED_TICKLESS 20285 drivers/timers/arch_alarm.c: Use uint64_t to avoid alarm 32-bit 20286 overflow. From ligd. 20287 - MAX11802: Fix compilation errors and allow setting PULL and SAMPLE 20288 registers. From Petteri Aimonen. 20289 - S25FL1: During a MTDIOC_GEOMETRY ioctl call, the driver was 20290 incorrectly reporting the blocksize to be the same as the erasesize. 20291 The blocksize should be 256 (the page size). This patch fixes that, 20292 and now the SmartFS configration is working. From Ken Pettit. 20293 - SYSLOG: nx_syslog's return value should include the timestamp length 20294 From Xiang Xiao. 20295 - SYSLOG: syslog_putc() calls sc_force in idle task even if interrupt 20296 buffer enabled. The following cases may hang randomly in the bring up 20297 phase: (1) boot up process and (2) suspend/resume process. Either 20298 case runs in the idle task context, so it's difficult to debug the 20299 hang issue if these output go through the interrupt buffer. From 20300 Xiang Xiao. 20301 - SYSLOG: Ensure interrupt log doesn't interlace in normal log. Don't 20302 call syslog_putc in syslog_default_write because syslog_putc will try 20303 to empty the interrupt buffer every time. From Xiang Xiao. 20304 - UART 16550: Fix UART flow control issue. UART_MCR_RTS need be high 20305 even UART_MCR_AFCE is enabled From zhangyuan7. 20306 - USB RNDIS Device: Fix buffer overrun check in rndis.c. The rndis 20307 driver has been working since 13 Nov 2017. However, I finally found 20308 that it depends on network and buffer configurations. If a receiving 20309 TCP packet is divided into smaller ones based on USB max packet size, 20310 this condition check works correctly. From Masayuki Ishikawa. 20311 20312 * ARMv7-A: 20313 20314 - ARMv7-A: Replicate the same fix was previously committed for the 20315 ARMv7-R. From Gregory Nutt. 20316 20317 * ARMv7-R: 20318 20319 - ARMv7-R: Fix error in cp15_flash_dcache. Change mcrne to mcr for 20320 unconditional dcache. From EunBong Song. 20321 20322 * ARMv7-M: 20323 20324 - ARMv7-M Interrupts: Correct all ARMv7-M architectures. Interrupts 20325 were not be disabled correctly on power up. Writing zero to the NVIC 20326 SET-ENABLE registers has no effect. In order to disable interrupts, 20327 it is necessary to write all ones to the NVIC CLEAR-ENABLE register. 20328 Noted by David Sidrane. From Gregory Nutt. 20329 20330 * Broadcom BCM2708 Drivers: 20331 20332 - BCM2708 Serial: Juha Niskanen's fix related to STM32 20333 CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in BCM2708. 20334 From Gregory Nutt. 20335 20336 * Intel x86: 20337 20338 - Qemu i486: Correct .bss, IDLE stack, heap organization. From Gregory 20339 Nutt. 20340 20341 * NXP/Freescale LPC43xx Drivers: 20342 20343 - LPC43 Ethernet: Fix Ethernet TX_EN pin definitions. TX_EN on LPC43xx 20344 can be routed via P0.1 and PC.4 in both MII and RMII mode. Before, 20345 P0.1 was hard-coded for MII and PC.4 was hard-coded for RMII. Also, 20346 the definitions used inconsistent naming (TXEN vs. TX_EN). From Jakob 20347 Haufe. 20348 - LPC43 Serial: Fix copy-paste error: g_usart1port->g_uart1port. From 20349 Dave Marples. 20350 - LPC43 SDMMC: Fix the LPC43 family SDMMC card access: Clocks were 20351 wrongly configured, way too fast because there is no primary divider 20352 on LPC4330, the LPC43_SDMMC_DELAY register was not being set, the 20353 LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong 20354 values. From Dave Marples. 20355 - LPC43 SDMMC: Corrected a problem in lpc43_dmasendsetup(). There was 20356 no linked DMA descriptor code on the send side. The end result was 20357 stalls while sending multiple sectors. This commit adds that in and 20358 the send code is working much better. From Dave Marples. 20359 - LPC43 SDMMC: With these changes the SDMMC card for LPC43 is now 20360 working properly: Timing was dependent on CPU speed rather than 20361 absolute time, end of transfer handling was a bit mixed up. It is 20362 possible for data to still be in the FIFO (i.e. not have reached the 20363 card) when a next write is requested, so we need to wait for that to 20364 complete. Interrupt Status could be carried over from one transfer 20365 episode to the next, corrupting progress. Multi-descriptor DMA 20366 writing simply wasn't implemented. From Dave Marples. 20367 20368 * NXP/Freescale LPC43xx Boards: 20369 20370 - Bambino-200E: Correct calculation of SDMMC clock configuration. The 20371 LPC43 has no SDMMC source clock divider. Error noted by Dave 20372 Marples. From Gregory Nutt. 20373 20374 * NXP/Freescale Kinetis: 20375 20376 - Kinetis: Remove all attempts to reprioritize interrupts. From Gregory 20377 Nutt. 20378 20379 * NXP/Freescale Kinetis Drivers: 20380 20381 - Kinetis I2C: I2C On failed reset re-initialization I2C and clocking. 20382 If a reset fails, we still must reinitializes the I2C block so that 20383 subsequent transfers will not cause a hard-fault due to the clock 20384 being off. If that transfer fails it can try to reset again. From 20385 David Sidrane. 20386 - Kinetis Serial: Juha Niskanen's fix related to STM32 20387 CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in Kinetis. 20388 From Gregory Nutt. 20389 20390 * NXP i.MXRT Drivers: 20391 20392 - i.MXRT Ethernet: The board would not come up if I ran Nuttx from cold. 20393 I dumped the PHY registers to see what the differences were and the 20394 PHY was coming up in NANDTree mode. This is a mode for testing 20395 connectivity between the PHY and the MAC. Switching this mode off in 20396 the PHY registers has fixed the problem. From Dave Marples. 20397 - i.MXRT Ethernet: Fix a race condition in setting up the Ethernet Tx 20398 transfer. From Dave Marples. 20399 - i.MXRT Ethernet: Corrections for the i.MXRT Ethernet: (1) Now the 20400 Ethernet is completely re-initialized when an error occurs by means of 20401 taking the interface down and back up but the PHY is _not_ 20402 renegotiated for that case because that is very time consuming and an 20403 error in the Ethernet is no reflection on the state of the PHY 20404 anyway. (2) Explicitly sets the expected PHY address to zero (this 20405 could be moved into the config rather than searching for it which 20406 takes ages, and it's zero anyway for this board (that's the broadcast 20407 address, and anything that cannot respond on that has multiple PHYs, 20408 so that would be a new board). (3) Allows for the renegotiation of 20409 the PHY to be optional when a reset is needed. If a non-renegotiated 20410 reset doesn't result in good comms to the PHY then it'll automatically 20411 be escalated to a renegotiated one. (4) Only performs a reset for 20412 errors that need it (the CRITICAL_ERROR define). The list of errors 20413 that need reset are somewhat arbitrarily chosen based on my prejudices 20414 and might need to be revisited, but certainly the jabber errors don't 20415 need reset, the partial packet is thrown away by the layer above 20416 anyway. (5) Re-loads the multicast table on reset. (6) Adds a bit 20417 more logging into the imxrt Ethernet module. From Dave Marples. 20418 - i.MXRT LPI2C: Fixes 2 bugs in the for IMXRT1050: (1) I2C time out and 20419 did not send STOP condition when sending single byte, (2) I2C could 20420 not receive bytes after repeated start. From Ivan Ucherdzhiev. 20421 - i.MXRT LPSRTC: SVNC LPCR register bits 0 & 1 are NOT reserved and 20422 are, in fact, needed to enabled the SRTC. Now the SRTC is working. 20423 From Ivan Ucherdzhiev. 20424 - LPC54 SDMMC: Add support for and SDMMC errata. It appears that now I 20425 can read the SD card successfully, but I get CRC errors when writing 20426 to the card. From Gregory Nutt. 20427 - LPC54 SDMMC: Ported Dave Marples fixes LPC43 SDMMC to the LPC54. 20428 From Gregory Nutt. 20429 - i.MXRT WDOG: Typos in bit definitions, wdog registers are 16 bits, 20430 wdog update has to be within 255 clocks of unlock, define board 20431 clocking based on divisor and muxes. From David Sidrane. 20432 20433 * NXP i.MXRT: 20434 20435 - i.MXRT: clockconfig bug fix: Fixed logic that was not clearing bits 20436 as ~ was missing in &= mask operations. Use values from the board.h 20437 file so set the Mux that selects the clock sources. Use board 20438 defined PODF values to select clock. Only configure USDHC2 clocks 20439 when board defines clocks. From David Sidrane. 20440 20441 * NXP i.MXRT Boards: 20442 20443 - IMXRT1050-EVK: Previous committed implemented SPI-based MMC/SD card 20444 support conditioned on CONFIG_MMCSD. This interferes with the 20445 implementation of MMC/SD card support using the SDIO-based 20446 peripheral. This commit renames that atypical support to *mmcsd_spi* 20447 and conditions using the SPI-based support on CONFIG_MMCSD_SPI which 20448 will then not interfere with the MMC/SD support that can be 20449 conditioned on CONFIG_MMCSD_SDIO. From Gregory Nutt. 20450 20451 * On Semi LC823450 Boards: 20452 20453 - LC823450: Fix up_allocate_heap() in lc823450_allocateheap2.c. For 20454 lc823450, heap area in flat build mode must start just after 20455 _eronly. Because bss/data area is allocated in lower address than 20456 text area in SRAM. See ld.scripts for details. Also, this change 20457 removes unused up_allocateheap.c From Masayuki Ishikawa. 20458 20459 * Silicon Labs EFM32 Drivers: 20460 20461 - EFM32 Serial: Juha Niskanen's fix related to STM32 20462 CONFIG_SERIAL_OFLOWCONTROL also applies to cloned logic in EFM32. 20463 From Gregory Nutt. 20464 - EFM32 USB Device: The epin_configure() function used the same eptype 20465 as the TxFIFO number for all endpoints. This should probably be the 20466 physical EP number, not the EP type. Suggested by Key Two. From 20467 Gregory Nutt. 20468 20469 * STMicro STM32 Drivers: 20470 20471 - STM32* SPI: Don't rely on SPI_CR1_SPE to determine if peripheral has 20472 been initialized. This change is needed specifically for the case 20473 where a boot loader sets the SPE bit before starting NuttX. In that 20474 case, the test in the SPI driver is wrong. This change fixes that by 20475 assuring that NuttX has booted and initialized at least once (whether 20476 or not SPE is set) before the driver starts refusing to initialize. 20477 From Anthony Merlino. 20478 - STM32 F0, F7, H7, L4 Serial: Fix use of CONFIG_SERIAL_IFLOWCONTROL 20479 where CONFIG_SERIAL_OFLOWCONTROL was intended. From Juha Niskanen. 20480 - STM32 TIM: Don't use hard-coded UIF interrupt in some functions. 20481 From raiden00pl. 20482 - STM32 (FS/HS), STM32F7, and STM32L4 OTGFS/HS Device: The 20483 epin_configure() function used the same eptype as the TxFIFO number 20484 for all endpoints. This should probably be the physical EP number, 20485 not the EP type. Suggested by Key Two. From Gregory Nutt. 20486 - STM32 F2: Fixes Kconfig options to include all STM32F20XX processors, 20487 not just STM32F207. Also removes redundant STM32_STM32F429 depends 20488 from Kconfig. STM32F4XXX already does this. From Anthony Merlino. 20489 - STM32 F4 DAC: STM32F407VG has only one DAC. NDAC=2 causes 20490 compilation error when trying to use e.g. STM32_DAC1_CR macro. From 20491 Petteri Aimonen. 20492 - STM32 F7 Serial: Force invalidation of data cache after DMA re-enable 20493 when returning from low-power mode From Juha Niskanen. 20494 20495 * STMicro STM32 Boards: 20496 20497 - B-L475E-IOT01A: Correct timer source clock frequencies. From Freemans 20498 Goden. 20499 - Nucleo-L432KC: Fix SPI pin definitions in board.h. From Daniel P. 20500 Carvalho. 20501 20502 * MIPS32: 20503 20504 - CP0 Definitions: Fix some copy-paste errors that cause malformed 20505 comments and syntax errors when certain CP0 CONFIG1 bits are 20506 referenced. Note in Issue 123 by Anonymous. From Gregory Nutt. 20507 - microMIPS: Reported by Anonymous in Bitbucket Issue #129: When MIPS 20508 port is built for microMIPS and then loaded as an application, the 20509 __start entry point is entered in microMIPS mode, but the CPU core 20510 initialization code there misses to set the config3ISAOnExc bit to 1. 20511 Subsequently, exceptions are entered in MIPS32 mode, but the code base 20512 was built for microMIPS. 20513 20514 * Microchip PIC32MZ: 20515 20516 - PIC32MZ Startup: In pic32mz-head.S, initialize the global pointer in 20517 all shadow sets. From Ouss4. 20518 20519 * Microchip PIC32MZ Drivers: 20520 20521 - PIC32MZ Serial: Fix a typo in assignment of TTYS0 to UART6 From Ouss4. 20522 20523 * Simulation: 20524 20525 - SIM Network Driver: Fix error 'invalid operands to binary &' From 20526 Xiang Xiao. 20527 20528 * C Library/Header Files: 20529 20530 - Fix typographical error in endian.h and resource.h From anchao. 20531 - include/net/if.h: Adds extern "C" guard in include/net/if.h From 20532 Anthony Merlino. 20533 - include/netinet/in.h: Per OpenGroup.org, type of sin_port in struct 20534 sockaddr_in must be in_port_t vs uint16_t. NOTE: in_port_t is 20535 typdef'ed as uint16_t anyway. From Gregory Nutt. 20536 - include/nuttx: Fix definitions used to access OS functions within the 20537 libraries. In the FLAT build, we must always set the errno and/or 20538 create cancellation points because the same library functions are used 20539 within the OS as are used by applications. This could cause issues 20540 for the OS but corrects some problems at the user interface. Noted by 20541 Federico Braghiroli in Bitbucket issue 121. From Gregory Nutt. 20542 - include/nuttx/clock.h: Fix uptime wrong if DEBUG_FEATURES and 20543 SCHED_TICKLESS enabled. From Xiang Xiao. 20544 - include/nuttx/fs/fs.h: Fix some backward parameters in a new macro 20545 definition. From Gregory Nutt. 20546 - include/nuttx/fs/fs.h: Register_mtddriver should depend on CONFIG_MTD 20547 not CONFIG_MTD_PARTITION From Xiang Xiao. 20548 - include/sys/socket.h: Renumber the socket types. They must begin at 20549 1, not zero. Socket type zero has a special meaning for some 20550 interfaces. For example, getaddrinfo() uses a socket type of zero to 20551 many any type of socket. The is no standard name for the 20552 any-type-socket, but macOS uses SOCK_UNSPEC. NuttX will do the same. 20553 Issue noted by Anthony Merlino. From Gregory Nutt. 20554 20555 - libs/libc: Correct some errors in psignal() and stpncpy(). From 20556 Lokesh B V. 20557 - libs/libc/math: Add variable convergence in log() and logf() to avoid 20558 hangs caused by failure to converge for very specific input values. 20559 Also includes a small change to log() and logf() that improves 20560 accuracy and convergence time. From Rajan Gill. 20561 - libs/libc/stdio: Fix conversion for format specifiers in sscanf() that 20562 appear right after a floating point format specifier. When 20563 performing a floating point conversion the parsing code could consume 20564 more than required characters from the input buffer. This made 20565 impossible to convert input of form "1.1K" using format "%f%c". Fix 20566 the issue by advancing the input buffer with the actual characters 20567 converted as a float point number. From Mihai Serban. 20568 - libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option 20569 does, indeed, make the printf family of functions much smaller. But 20570 it also adds a lot of complexity and makes the functions 20571 non-standard. Removing this might break some of the tinier platforms 20572 but it is the best thing to do for long term maintenance for for 20573 OpenGroup.org compliance. 20574 - libs/libc/stdio: Update to vsprintf(). This resolves the integer 20575 field width problem if Issue 35 for the cases of integer, long and 20576 long long integer types. The output now matches the output form 20577 glibc. From Gregory Nutt. 20578 - libs/libc/string: Correct the return pointer value from stpncpy() for 20579 the case where the NUL terminator is transferred. From Gregory Nutt. 20580 - libs/libc/string: Fix strrchr() so that it considers null terminator 20581 as part of string. From Petteri Aimonen. 20582 - libs/libc/wqueue: Eliminate a race condition noted by Xiang Xiao. 20583 Use sigprocmask() so that we do not lose a signal. From Gregory Nutt. 20584 - libs/libnx/nxfonts: Fix kerning of 'I' in Sans17x22 font. From 20585 Petteri Aimonen. 20586 - libs/libnx/nxfonts: In nxfonts_getfont(), avoid unnecessary warnings 20587 for other whitespace chars also. From Petteri Aimonen. 20588 - libs/libnx/mxmu: NXMU now re-validates window pointer for mouse 20589 events. NXMU caches the previous window pointer so that further mouse 20590 events can be sent to the same window. However, if the window is 20591 destroyed while mouse button is held down, the pointer may become 20592 invalid and cause a crash. This patch revalidates the pointer before 20593 using it. From Petteri Aimonen. 20594 - libs/libnx/nxtk: nxtk_bitmapwindow: Fix warning message when bitmap is 20595 fully off-screen. From Petteri Aimonen. 20596 20597 * Build System: 20598 20599 - Fix issue with libcxx build. This was changed multiple times, but 20600 should be fixed now. From Anthony Merlino. 20601 - configs/Makefile and tools/Config.mk: Move single file copy to the 20602 new function COPYFILE. This fixes the Windows native build case when 20603 there is no cp or cp does not recognize Windows paths. From Anatol 20604 Ivanov. 20605 - tools/Config.mk and tools/Makefile.win: Force use 'cmd' for shell 20606 with windows native build From Anatol Ivanov. 20607 - tools/Directories.mk: Correct the path to the installed libcxx 20608 directory. From Gregory Nutt. 20609 - tools/Makefile.win/unix: Staging directory (and its libraries) should 20610 be removed on 'make clean' (issue noted by Dave Marples). From 20611 Gregory Nutt. 20612 20613 - apps/Directory.mk: If the current directory contains a Kconfig file 20614 and MENUDESC is not defined, then Directory.mk must not trash the 20615 Kconfig in the current directory. From Gregory Nutt. 20616 - apps/Makefile: Fix Windows native build patch extension. From Anatol 20617 Ivanov. 20618 20619 * Other Tools: 20620 20621 - tools/Config.mk: Fix an error in RWILDCARD implementation From 20622 Anthony Merlino. 20623 - tools/configure.c: Add missing '\n' in printf statement 20624 - tools/configure.c: Add missed -g option to getopt() string. From 20625 Anatol Ivanov. 20626 - tools/configure.c and tools/configure.sh: Fix Windows native 20627 pre-build kconfig-conf incompatibility. From Anatol Ivanov. 20628 - tools/csvparser.h: Extend MAX_PARMSIZE to 256. Fixes this issue: 20629 70: Parameter too long: ... From Xiang Xiao. 20630 - tools/link.bat: Fix .fakelink creation. From Anatol Ivanov. 20631 - tools/mkdeps.c: Fix '\0' missing with MinGW. From Anatol Ivanov. 20632 20633 * NSH Library: apps/nshlib: 20634 20635 - apps/nshlib: Correct maximum number of arguments that can be provided 20636 to the mksmartfs command. From Eunbong Song. 20637 - apps/nshlib: Add fflush to nsh_consolewrite(). This resolves this 20638 problem: 'cat /dev/ttyCP &' followed by 'echo ls >/dev/ttyCP'. In 20639 that case we can't get the 'ls' result immediately, because 'cat' cmd 20640 uses nsh_consolewrite() and that uses fwrite with no fflush. We can 20641 get the 'ls' result after type '\n', because nsh will fflush output 20642 when get '\n'. From ligd. 20643 - apps/nshlib: nsh_catfile() should not append '\n' if the last char in 20644 file is already '\n' From Xiang Xiao. 20645 - apps/nshlib: Fix warning g_oldpwd defined but not used 20646 [-Wunused-const-variable] in nsh_envcmds.c. From Xiang Xiao. 20647 20648 * Examples/Tests: apps/examples: 20649 20650 - apps/examples/adc/Kconfig: CONFIG_BOARDCTL_ADCTEST does not exist 20651 anymore and should removed as a dependency. From Eunbong Song. 20652 - apps/examples/webserver/Kconfig: The webserver "app" allows for DHCP 20653 client to be enabled. However, the Kconfig infrastructure does not 20654 contain EXAMPLES_WEBSERVER_DHCPC config. Based on patch from 20655 "Anonymous" attached to Bitbucket Issue #130. From Gregory Nutt. 20656 20657 * System Utilities: apps/system: 20658 20659 - apps/system/hexed: Fix memory leak From zhuyanlin. 20660 - apps/system/i2c: Fix i2c_msg freq initialization problem. Typo 20661 prevented I2C frequency initialization in a struct i2c_msg. From 20662 dongjiuzhu. 20663 - apps/system/system: Fix warning when passing argument 6 of 20664 'task_spawn' from incompatible pointer type 20665 [-Wincompatible-pointer-types] From Xiang Xiao. 20666 20667 * Network Utilities: apps/netutils: 20668 20669 - Correct some network-related configuration variable names. All *_MTU 20670 defines were changes to *_PKTSIZE gut that was not reflected in 20671 apps/ From Gregory Nutt. 20672 - apps/netutils/netlib/netlib_parsehttpurl.c: Correct handling of long 20673 URLs as noted in Bitbucket issue #119 (in the nuttx/ repository, not 20674 the apps/ repository). From Gregory Nutt. 20675 - apps/netutils/codecs: "dst" overflow protection when base64 string 20676 ends with "=" From Aleksandr Vyhovanec. 20677 - apps/include/netutils/ipmsfilter.h: Eliminate error generated by bad 20678 pre-processor logic. From Gregory Nutt. 20679 20680 * GPS Utilities: apps/graphics: 20681 20682 - apps/graphics/NxWidgets: Fix garbage returned when 20683 CCycleButton::getValue() is called after removeAllOptions(). 20684 CScrollingPanel should not draw outside the widget area. From 20685 Petteri Aimonen. 20686 20687NuttX-7.28 Release Notes 20688------------------------ 20689 20690The 128th release of NuttX, Version 7.28, was made on January 19, 2019, 20691and is available for download from the Bitbucket.org website. Note 20692that release consists of two tarballs: nuttx-7.28.tar.gz and 20693apps-7.28.tar.gz. These are available from: 20694 20695 https://bitbucket.org/nuttx/nuttx/downloads 20696 https://bitbucket.org/nuttx/apps/downloads 20697 20698Both may be needed (see the top-level nuttx/README.txt file for build 20699information). 20700 20701Additional new features and extended functionality: 20702 20703 * Core OS: 20704 20705 - Critical Section Monitor: Adds data collection logic in support of 20706 pre-task monitoring critical sections and pre-emption state. From Gregory 20707 Nutt 20708 - Critical Section Monitor: Add support for global pre-emption and 20709 global critical sections to monitor as suggested by Xiang Xaio. From 20710 Gregory Nutt 20711 - Interrupt Time: Measurement of interrupt handler duration used to 20712 be available only in Tickless mode since it used the high resolution 20713 Tickless timer to measure interrupt time. This change adds 20714 CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the 20715 interrupt duration calculation to use the same high-resolution, 20716 platform-specific timer as is used with the Critical Section Monitor. 20717 This leads to two improvements: (1) You can now measure interrupt 20718 duration in non-Tickless mode, and (2) in either mode, the interrupt 20719 duration and the critical section measures will use the same 20720 high-resolution timer and should, therefore, never be any discrepancy 20721 due to different clock sources. From Gregory Nutt 20722 - Context Switching Protection: Add debug assertions before each call 20723 to up_block_task() to assure that there is no attempt to block an 20724 IDLE task. From Dave Marples 20725 - init Task: Allow the init task priority to be configurable. From 20726 David Sidrane 20727 - pthreads: Implement pthread_key_delete(). This involves some minor 20728 changes to the group data structure. From Gregory Nutt 20729 20730 * File Systems/Block and MTD Drivers 20731 20732 - ProcFS: Extended the process ID ProcFS output to show per-thread 20733 maximum time for pre-emption disabled and maximum time within a 20734 critical section. From Gregory Nutt 20735 - NXFFS: Pass unrecognized IOCTL commands to the contained MTD 20736 driver. From Daniel P. Carvalho 20737 - LittleFS: Adds an initial port the ARM mbed littlefs to NuttX. This does 20738 not include FLASH formatting utilities. Depends on CONFIG_MTD_BYTE_WRITE. 20739 From lihaichen 20740 - AT25 MTD Driver: Added support for AT25DF081A serial flash chip. 20741 From Marc Rosen 20742 - MTD Configdata Device: Extends the MTD configdata device with the 20743 following features / additions: 20744 1. Configurable option to use named config items instead of enumerated 20745 ID/Instance numbers. 20746 2. Ability to iterate through the existing configdata items in the 20747 /dev/config device. 20748 3. Ability to "unset" a configdata item. 20749 4. Ability to perform "flash_eraseall" on the /dev/config device. 20750 From Ken Pettit 20751 20752 * Networking/Network Drivers: 20753 20754 - Telnet Driver: Add NAWS and poll interface to telnet for screen size 20755 negotiation used with termcurses. From Ken Pettit 20756 20757 * Wireless/Wireless Drivers: 20758 20759 - BLE HIC Core: Add second RX work function From Lwazi Dube 20760 - BLE IOCTL Commands: Add SIOCBTCONNECT and SIOCBTDISCONNECT ioctl 20761 commands From Lwazi Dube 20762 - CC2564: Add cc2564 HCI UART driver. From Lwazi Dube 20763 20764 * Graphics/Display Drivers: 20765 20766 - Sitronix ST7032i: Add support to Alphanumeric Sitronix ST7032i 20767 display From Alan Carvalho de Assis 20768 - NXP TDA19988: This commit brings in a complete, but untested, 20769 implementation of a driver for the TI TDA19988 HDMI Encoder. This encoder 20770 is used on the Beaglebone Black board. Since this driver is untested, it 20771 requires CONFIG_EXPERIMENTAL in the configuration. From Gregory Nutt 20772 20773 * Crypto: 20774 20775 - crypto/aes.c: This change provides an improved AES cipher API in 20776 addition to the existing routines. The reasons for this new API are: 20777 1) better performance, giving the possibility to avoid re-setting-up 20778 the key for each AES block when the same key is used multiple times. 20779 This is important for the current single user of AES, which is 20780 related to storage and FTL. And 2) suitable for simultaneous use of 20781 multiple AES keys, which will be required by the upcoming crypto 20782 framework. It retains compatibility with the previous API, so there 20783 is no need to change anything else right now. From Sebastien Lorquet 20784 20785 * Other Common Device Drivers: 20786 20787 - MMCSD SDIO: The mmcsd_sdio driver makes calls for dcache 20788 invalidation through the chip specific architecture function 20789 SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use 20790 arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache(). 20791 20792 This commit includes additional changes to mmcsd_sdio.c. I 20793 created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to 20794 invalidate store-into mode dcaches after the DMA transfer. I 20795 have been using SDIO_DMADELYDINVLDT() for several weeks now and 20796 it has fixed the problems that I previously reported regarding 20797 non-cache aligned buffer invalidation errors (for my store-through 20798 dcache). However, it does not permit use of unaligned DMA buffers 20799 for store-into mode dcaches. 20800 20801 SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig 20802 file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified 20803 all the stm32f7 chips to select it. From Bob Feretich 20804 - SPI Lower Half Interface: Extend the HW features supported by SPI. 20805 It now supports a deferred DMA trigger hardware configuration. From 20806 Dave Marples 20807 - DS28E17 1-Wire Driver: Optimize I2C write followed by read to same 20808 address. From Juha Niskanen 20809 - LMP92001: Add support for the TI LMP92001 Multi-channle DAC/ADC 20810 device.

From Ouss4 20816 - Sensirion SCD30: Driver for Sensirion SCD30 CO2 sensor. From Jussi 20817 Kivilinna 20818 - Sensirion SGP30: Driver for Sensirion SCD30 gas sensor. From Jussi 20819 Kivilinna 20820 - Sensirion SPS30: Driver for Sensirion SCD30 particulate matter sensor. 20821 From Jussi Kivilinna 20822 - USB CDC/ACM Device: When implemented usb cdc on nrf52840, I found 20823 some issues with cdc driver: 20824 1. Lost data when receiving buffer is full; 20825 2. Low-water mask implement issue; 20826 3. Re-flush cdc buffer when enabling 20827 4. Serial dma is conflict with cdc , modify the serial.h 20828 From Levin Li 20829 20830 * MIPS32: 20831 20832 - Configuration System: Allow Penguino for windows for the Windows 20833 Ubuntu platform as well. 20834 20835 * Maxim Integrated MAX326xx 20836 20837 - MAX32660: Support for the MAX32660 was added (along with partial 20838 support for other members of the MAX326xx family). The initial port 20839 includes Clock configuration, timer, GPIO pin configuration, ICC, 20840 and UART. Additional untested drivers are complete and ready for 20841 testing: DMA, GPIO interrupts, SPI0 Master, TC, WDT. The following 20842 drivers are not yet implemented: I2C and I2S. 20843 20844 * Maxim Integrated MAX326xx boards 20845 20846 - MAX32550-EVSYS: Basic support for the Maxim Integrated MAC3X660 20847 EVSYS is included. A basic NSH configuration is available and is 20848 fully functional. Includes unverified support for an SPI0-based 20849 SD card. 20850 20851 * Microchip/Atmel SAMD21/L21 Drivers: 20852 20853 - SAMD21/L21: Adds a complete ADC header file for SAMD21 and a partially 20854 complete ADC header file for the SAML21. From Alexander Vasiliev 20855 - SAMD21/L21: Export sam_i2c_master_initialize(int bus) to be used by 20856 board config. From Alan Carvalho de Assis 20857 20858 * Microchip PIC32MZ Drivers: 20859 20860 - PIC32MZ I2C: Add support for the I2C bus. From Ouss4 20861 20862 * ARMv7-A 20863 20864 - ARMv7-A MMU: Use TLBIMVA vs TLBIMVAAIS to invalidate the Cortex-A8 20865 cache. From Petro Karashchenko 20866 20867 * ARMv7-M 20868 20869 - Cortex-M7 Cache: This commit adds a new function 20870 arch_invalidate_dcache_by_addr(). It takes the same parameters as 20871 arch_invalidate_dcache(), but performs invalidation of only the lines 20872 in cache that need to be invalidated. This new function could be 20873 used as a a direct replacement for arch_invalidate_dcache(). From 20874 Bob Feretich 20875 - ARMv7-M: In the current implementation we only use very high 20876 priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but 20877 that means there are loads of lower priority ones that are 20878 effectively unused. I have *not* changed the semantics of these 20879 levels but have 'shifted' them to be based around the midpoint of the 20880 available interrupts (0x80) rather than at the top end....that allows 20881 for interrupts to be defined above (or, indeed, below) them as needed 20882 by the application. This should have no functional effect on 20883 existing code but adds in a clean capability to define higher 20884 priority interrupts. From Dave Marples 20885 20886 * Broadcom BCM2708: 20887 20888 - BCM2708: Remove all support for the BCM2708/2835. This was added 20889 only for support of the RaspberryPi Zero board which was previously 20890 removed. The support was minimal and unverified. The removed files 20891 can still be found in the Obsoleted directory. From Gregory Nutt 20892 20893 * Broadcom BCM2708 Boards: 20894 20895 - Raspberry Pi Zero: Remove the partial support for the Raspberry Pi 20896 Zero. This port was started with the best of intentions but was 20897 never completed. The board support can still be found in the 20898 Obsoleted repository. From Gregory Nutt 20899 20900 * Nordic NRF52 Boards: 20901 20902 - Improve LED handling #if~#endif in nrf52_autoleds.c and 20903 nrf52_userleds.c 20904 Add Adafruit Feather nRF52 board LED support 20905 Add Adafruit Feather nRF52 board 20906 Add nrf52-generic 20907 Replace 'pca10040' with 'generic' 20908 Copy from nrf52-pca10040 to nrf52-generic 20909 From Zou Hanya 20910 20911 * NXP i.MX RT Drivers: 20912 20913 - i.MXRT: Add PIT, GPT, and QIMER(TMR) header files From David Sidrane 20914 - i.MXRT: Add FLEXPWM.

From Gregory Nutt 21017 - STM32F4 Discovery: If the Critical Section Monitor, modify the 21018 ITM_LAR register to assure that the DWT cycle counter is enabled. 21019 Suggested by Dave Marples. From Gregory Nutt 21020 - STM32F4 Discovery: Add board support to display ST7032i From Alan 21021 Carvalho de Assis 21022 - STM32F4 Discovery: Add loadable application build support in 21023 Make.defs From Masayuki Ishikawa 21024 - STM32F4 Discovery: Update RNDIS configuration: (1) Add NFS and adjusted 21025 stack size for usermain and telnetd client. (2) Add support for loadable 21026 application and ping.

From Mateusz Szafoni 21032 - configs/nucleo-l073rz: Support for nrf24l01. From Mateusz Sfafoni 21033 21034 * TI CCxx: 21035 21036 - CC13x0 family and CC13x2/CC26x2: Basic, minimal support was added 21037 for these two chip families. This is a Work-In-Progress: There is 21038 just enough logic in place to support a simple NSH configuration. 21039 However, the port is still missing certain, necessary hooks into the 21040 TI ROM-based 'DriverLib'. As a result, the support is not fully code 21041 complete and is totally untested. Support for the CC26x2, which is 21042 nearly identical to the CC13x2 is fragmentary. Stay tuned. 21043 Hopefully full support will be available in NuttX 7.29. 21044 21045 * TI CCxx Boards: 21046 21047 - LAUNCHL-CC1312R1: Board support is available for the TI 21048 LAUNCHL-CC1312R1. That board support consists only of an unverified 21049 NSH configuration. The primary purpose of this port for the time 21050 being is simply support the core architecture bring-up. 21051 21052 * TI AM335x: 21053 21054 - AM335x: Adds initial support for the TI AM355x family. 21055 - AM335x: Add minimal wdog logic needed to disable the watchdog timer. 21056 Otherwise, the board is rebooted after certain time expires while NuttX is 21057 running. From Petro Karashchenko 21058 - AM335x: Switch to DMTimer2 for system tick generation. U-Boot does not 21059 enable DMTimer1ms clocks hence it is not possible to use it until 21060 implementation in am335x_clockconfig.c is ready. From Petro Karashchenko 21061 21062 * TI AM335x Boards: 21063 21064 - Beaglebone Black: Initial port for BeagleBone Black board support 21065 (TI AM335x family based on Cortex-A8).

From Gregory Nutt 21086 - tools/detab.c: Add detab.c which will convert all tabs in a file to 21087 spaces. From Gregory Nutt 21088 - tools/lowhex.c: Add lowhex.c that will convert hexadecimal constants 21089 in a file to use lower case representation. From Gregory Nutt 21090 - tools/mkconfig.c: Add definitions to distinguish between tristate 21091 'y' and 'm' options. From Gregory Nutt 21092 - tools/nxstyle.c: Add logic to detect long lines. From Gregory Nutt 21093 - tools/nxstyle.c: Add -h for help. From Gregory Nutt 21094 21095 * Libraries/Header Files: 21096 21097 - include/nuttx/lcd/edid.h: Add EDID definitions From Gregory Nutt 21098 - libs/libc/netdb: Make DNS retries configurable From Juha Niskanen 21099 - libs/libc/netdb: Harden query logic against DNS spoofing. This 21100 commit implements most of the RFC 5452 guidelines for making DNS more 21101 resilient. We now verify response matches against what was queried 21102 and use unpredictable query IDs. It is also checked that response 21103 come from correct DNS server. Also fixes a buffer overflow when 21104 querying hostnames longer than CONFIG_NETDB_DNSCLIENT_NAMESIZE. From 21105 Juha Niskanen 21106 - libs/libc/netdb: Support multiple IP addresses per hostname From 21107 Juha Niskanen 21108 21109 * NSH: apps/nshlib: 21110 21111 - apps/nshlib: Add support to use SLCD as NSH Console From Alan Carvalho de 21112 Assis 21113 - apps/nshlib: Add support for CROMFS start-up script. From David Sidrane 21114 - apps/nshlib: Add var expansion in NSH parse. From Daniel Agar 21115 - apps/nshlib: Display built-in apps using multi-column mode like the NSH 21116 commands. From Ken Pettit 21117 - apps/nshlib: In all multi-column help output, calculate an optimal column 21118 width rather than using a hard-coded width that may or may not be 21119 appropriate. Also make the number of rows presented dependent upon the 21120 maximum width of the widest column. From Gregory Nutt 21121 - apps/nshlib: Adds addroute command options for setting default gateway. 21122 Like 'addroute default <ipaddr> <interface>'. From Anthony Merlino 21123 21124 * Examples/Tests: apps/examples: 21125 21126 - apps/examples/battery: Add Battery Charger Monitor Example From Alan 21127 Carvalho de Assis 21128 21129 * System Utilities: apps/system 21130 21131 - apps/system/configdata: Adds an "cfgdata" command which allows 21132 manipulation of the /dev/config items via the command line. One such use 21133 for this utility would be to set a "macaddr" configdata item, etc. The 21134 utility is sort-of like a u-boot env variable edit function: 21135 21136 For instance, to set a "macaddr" when the new CONFIG_MTD_CONFIG_NAMED 21137 option is selected, you would do: 21138 21139 nsh> cfgdata set macaddr [0xfc 0x01 0x0b 0x45 0xa1 0x12] 21140 (The brackets denotes an array of bytes) 21141 nsh> cfgdata set hostname myboard 21142 21143 or using the old ID,INSTANCE numeric method: 21144 21145 nsh> cfgdata set 0,0 [0xfc 0x01 0x0b 0x45 0xa1 0x12] 21146 (The brackets denotes an array of bytes) 21147 nsh> cfgdata set 1,0 myboard 21148 21149 You can also display all config items: 21150 21151 nsh> cfgdata print all 21152 Name Len Data 21153 macaddr 6 0xFC 0x01 0x0B 0x45 0xA1 0x12 21154 hostname 8 myboard 21155 21156 From Ken Pettit 21157 - apps/system/critmon: Add a daemon to monitor critical section usage. From 21158 Gregory Nutt 21159 - apps/system/nsh: Set NSH priority if the NSH task was scheduled at a 21160 different priority than the configured priority. From Gregory Nutt 21161 - apps/system/nxplayer: Introduce CONFIG_NXPLAYER_MAINTHREAD_STACKSIZE. From 21162 Masayuki Ishikawa 21163 - apps/system/termcurses: Addition of termcurses libraries in 21164 apps/system/termcurses From Ken Pettit 21165 - apps/system/vi: New feature additions 21166 1. Vi startup feature to prepend the current working directory to the 21167 supplied filename if it does not start with '/' absolute path 21168 specifier. This allows editing files in the current directory 21169 without needing to fully qualify the filename. 21170 2. Standard '~' empty screen line characters for proper identification 21171 of empty '\n' only lines at the end of the file. 21172 3. Moving into insert or append mode now prints '--INSERT--' in the 21173 status line and clears it upon exit. 21174 4. Integration with termcurses to detect special keystrokes and to 21175 handle terminal type differences. Haven't yet converted all vt100 21176 print codes to termcurses equivalents. 21177 5. Support for up, down, left, right arrows, page-up, page-down keys in 21178 command mode. 21179 6. Added 'b' command to move cursor 'b'ack to previous word. Honors the 21180 command repeat value for multiple word moves. 21181 7. Added 'w' command to move cursor to next 'w'ord. Honors the command 21182 repeat value for multiple word moves. 21183 8. Added 'f' and 't' commands to find characters on the current line. 21184 Honors the command repeat value. 21185 9. Added the find 'n'ext command to repeat the previous find operation. 21186 10. Added the 'H', 'M', and 'L' commands to move the cursor to top, 21187 middle and bottom of the display. 21188 11. Extended yank/paste to manage a paste buffer with character mode in 21189 addition to line mode. Character mode allows cut / paste of 21190 individual characters or groups of characters vs. full lines. 21191 12. Added support in the 'd'elete and 'y'ank commands for character mode 21192 deletions such as 'dw', 'dfa', '2yw', etc. 21193 13. Added support in paste routine for multiple paste using command value 21194 argument. 21195 14. Added support for the 'D' and 'C' delete and change to end of line 21196 commands. 21197 15. Added support for 's'ubstitute key ('x' followed by insert mode). 21198 16. Modified yank / paste allocation scheme to avoid repeated alloc and 21199 free of paste buffer. Uses a minimum allocation size scheme and only 21200 does free / realloc when paste does not fit. If the paste is smaller 21201 than the current allocation and the current allocation is larger than 21202 the threshold, then the buffer is freed and a smaller buffer 21203 allocated. Otherwise the existing buffer is used. 21204 17. Support for 'P'aste before current cursor position. 21205 18. Support for '?' reverse search mode. 21206 19. Support for 'J'oin next line with current line command. 21207 20. Printing of current row,col in status line of display. 21208 21. Command repeat '.' support for commands that modifiy text. 21209 22. Support in replace / insert mode for arrow keys, PGUP / PGDN, HOME, 21210 and END. Using these will cause the command repeat buffer to reset 21211 such that only the last text addition after a cursor movement is saved. 21212 23. Added 'X' delete previous command. 21213 24. Added "gg" go to top of document command sequence. 21214 25. Added "ZZ" save and quit command (equivalent to :wq). 21215 26. Implemented '^' goto first non-whitespace on current line, along with 21216 '+' and '-' goto first non-whitespace on next / previous line. 21217 27. Added CR / LF goto first non-whitespace on next line in command 21218 mode. From Ken Pettit ? 21219 21220 * Network Utilities: apps/netutils: 21221 21222 - apps/netutils/webserver: The webserver/httpd app is was broken when script 21223 support was enabled (CONFIG_NETUTILS_HTTPD_SCRIPT_DISABLE). The root cause 21224 has been tracked down to the "Content-length" not being available ahead of 21225 time in this case (length of -1 passed to send_headers() ). On the other 21226 hand, the server closing the socket does not result in FIN being sent to 21227 the browser either (FIN not supported by NuttX yet). 21228 21229 Simple solution: Add support for HTTP Chunked Encoding to webserver/httpd. 21230 The change is simple. It adds a configuration option to enable chunked 21231 encoding. When enabled, the implementation will auto-detect the cases where 21232 content length is not available ahead of time, and will automatically 21233 engage chunked encoding transfers. 21234 21235 Without this patch, the browser/client hangs forever, as it is expecting 21236 more data. With this patch, the browser displays the content. From Vlado 21237 Vidovic 21238 21239 * Wireless Utilities: apps/wireless: 21240 21241 - apps/wireless/bluetooth/btsak: Add connect and disconnect commands to 21242 btsak. From Lwazi Dube 21243 21244 * Graphic Utilities: apps/graphics: 21245 21246 - apps/graphics/pdcurs34: Integration of termcurses into pdcurses, plus 21247 pdcurses updates for multi-thread support From Ken Pettit 21248 - apps/graphics/pdcurs34: Adds a configuration option to pdcurses to enable 21249 line-drawing character (ALTCHARSET) when using the short 16-bit chtype. 21250 This is done by limiting the characters to 7-bit ASCII values and using the 21251 8-th bit as the A_ALTCHARSET bit. This allows a significant RAM savings 4K 21252 - 20K depending on terminal size) while still allowing the nicer 21253 line-graphic characters for border drawing. From Ken Pettit 21254 21255 * Testing: apps/testing: 21256 21257 - apps/testing/ostest: Add test for pthread-specific data. From Gregory 21258 Nutt 21259 21260Bugfixes. Only the most critical bugfixes are listed here (see the 21261ChangeLog for the complete list of bugfixes and for additional, more 21262detailed bugfix information): 21263 21264 * Core OS: 21265 21266 - Assertions: Identify the running task correctly when dumping task 21267 state information. It takes time to switch to the target task after 21268 g_readytorun has been modified. If panic/assert happen during this 21269 period, the dump will contain the incorrect and confusing information 21270 due to the difference between the real running task and the return 21271 value of this_task(). This change resolve this problem by adding 21272 g_running_task to track the real running task through the context 21273 switch. From Xiang Xiao 21274 - Assertions: Correct duplicated logic from commit 21275 dbf01d12b7321d1b48b68d3b69842a853b049376. Checking for PID == zero 21276 is not a valid way to test for the IDLE task in all configurations! 21277 This is only true in the single CPU configuration. In multiple CPU 21278 configurations, there will be a separate IDLE task for each CPU with 21279 a different PID and an alternative check must be used. NOTE: The 21280 logic fixed in some places still lacks sufficient intelligence in SMP 21281 mode to find the right stack for the CPU IDLE thread and could still 21282 show the wrong stack. From Gregory Nutt 21283 - Interrupt Prioritization: Remove all driver-specific logic that may 21284 set the interrupt priority to anything but the default. There is no 21285 good reason to change the interrupt priority unless you just want to 21286 debug a difficult problem. OR if you want to use high priority 21287 interrupts. In that case the specific interrupt priorities will need 21288 to be set by board-specific logic. From Gregory Nutt 21289 - Memory Management: Revert "This patch prevent heap corruption as in 21290 below case." This solution to the problem noted by EunBong Song 21291 results in major memory fragmentation and out-of-memory 21292 conditions on the PX4 platform. On that platform the lower priority 21293 work queue is very low priority and essentially never runs when the 21294 system is busy. As a result, the systems gets slowly starved of 21295 memory until failures and bad behaviors begin to occur. From Gregory Nutt 21296 - Memory Management: This is a replacement for EunBong Song's reverted 21297 change. This change adds (1) logic in getpid() to return an error instead 21298 of the PID if the (apparent) currently executing task is not marked as 21299 RUNNING. Then (2) mm_trysemaphore() (the root implementation of both 21300 kmm_trysemaphore() and umm_trysemaphore()) will know that the (apparent) 21301 running task cannot be the holder of the semaphore. How could the 21302 non-running task be trying to get the MM semaphore? I think only in the 21303 exact scenario that Eunbong Song has described. So this new solution 21304 should provide the same protection as the original change but without the 21305 bad consequences to memory usage. From Gregory Nutt (with corrections 21306 from David Sidrane) 21307 - Memory Management: In implementation of calloc(), verify that the number of 21308 elements times the size of an element will not overflow type size_t. This 21309 is required by the SEI CERT C coding style and resolves anonymous Bitbucket 21310 Issue #139 From Gregory Nutt 21311 - sigtimedwait(): Remove unnecessary disable of pre-emption. From 21312 Gregory Nutt 21313 - _exit(): Update all architecture-specific _exit() implementations 21314 so that they correctly call the scheduler instrumentation layer for 21315 the new task that runs when the old one exits. This missing 21316 instrumentation was confusing the Critical Section Monitor logic with 21317 uses this instrumentation to track the state of critical sections. 21318 From Gregory Nutt 21319 - sched_foreach(): sched_foreach() should not have to hold the 21320 critical section over the entire traversal. It should be acceptable 21321 to simply only the critical section while one entry is being 21322 processed (the caller can always call sched_foreach within a critical 21323 section is greater stability is needed). From Gregory Nutt 21324 - task_spawn(): Correct description of input parameters to 21325 task_spawn_exec(). Noted by: JeongchanKim From Gregory Nutt 21326 21327 * Crypto: 21328 21329 - crtypo/: This change: 21330 21331 Avoids the use of up_aesinitialize() entirely, which resolves 21332 dependency problems, because this function does not make sure that 21333 an actual hardware aes implementation was made available: each SoC 21334 is now responsible to ensure the AES hardware is initialized before 21335 first use. This applies to lpc43xx, stm32 and sam34. 21336 21337 Remove definitions of the NEVER used aes_init and aes_update 21338 operations. The new AES API will be more suitable. 21339 21340 From Sebastien Lorquet 21341 21342 * File System/Block and MTD Drivers: 21343 21344 - opendir(): Corrects a problem with opendir() noted by Petteri 21345 Aimonen in Bitbucket Issue 132: "opendir() fails for FAT filesystem 21346 with trailing slash in path". I see the following behaviour on NuttX 21347 7.26, where I have SD card mounted on /flash and a directory called 21348 "frm" on it: 21349 21350 opendir("/flash") returns (DIR *) 0x1000c580 21351 opendir("/flash/") returns (DIR *) 0x1000c5d0 21352 opendir("/flash/frm") returns (DIR *) 0x1000c620 21353 opendir("/flash/frm/") returns (DIR *) 0x0 21354 21355 From POSIX specs for opendir(): "A pathname ... that ends with one or 21356 more trailing slashes shall be resolved as if a single dot character 21357 ( '.' ) were appended to the pathname." So for mount points, 21358 opendir() works correctly, but for FAT32 filesystem it fails to open 21359 directory if the path has a trailing slash... 21360 21361 NOTE: You would not see this problem if you call opendir() indirectly 21362 in NSH (like 'ls -R /') because NSH contains logic to remove trailing 21363 '/' characters from paths. From Gregory Nutt 21364 - dup()/dup2(): dup() and dup2() were broken some time back. 21365 fs_dupfd() was return returning OK on success, not the file 21366 descriptor of the duplicated fd. From David Sidrane 21367 - ProcFS: Remove the unnecessary critical section From Xiang Xiao 21368 - CROMFS: Fix hardfault. From David Sidrane 21369 - SmartFS MTD Driver: Fix smart_write_alloc_sector sector size mapping. 21370 Was not correctly calculating the encoded sector size for small (256) 21371 byte or large (>= 4096 byte) sectors. Noted by Daniel P. Carvalho. 21372 Fix from Ken Pettit 21373 - AT25 MTD Driver: Fixed missing opening parenthesis. From Marc Rosen 21374 - MTD Configdata MTD Driver: Check return value mtdconfig_readbytes(). 21375 From Jussi Kivilinna 21376 - S25FL1 MTD Driver: Minor change for the s25fl1 QSPI FLASH driver which 21377 fixes additional sectorshift vs. pageshift confusion. From Ken Pettit 21378 21379 * Networking/Network Drivers: 21380 21381 - All network drivers! Change pre-processor logic that selects the 21382 high priority work queue or gives preferential treatment to the high 21383 priority work. All network logic must run on the low priority work 21384 queue! Or suffer the consequences. From Gregory Nutt 21385 - Socket Clone/Dup: On a failure to start the TCP monitor, the cloned 21386 socket is closed but is not properly freed, leaving it attached to a 21387 TCP connection structure with the wrong reference count. From 21388 Gregory Nutt 21389 - ARP: Fix whitespace after ARPHRD_IEEE80211 in ARP header file. From 21390 Daniel Agar 21391 - 6LoWPAN: Fixes decompression of ipaddr from MAC address. The logic 21392 used to populate the IP from the radio address should match 21393 sixlowpan_ipfromsaddr/sixlowpan_ipfromeaddr From Anthony Merlino 21394 - 6LoWPAN: Fixes logic surrounding the Universal/Local bit. This bit 21395 represents whether the IID is locally/globally administered. The U/L 21396 bit is bit 1 of the MSB of the EUI-64. It should only be inverted in 21397 cases where there is a full EUI-64. In cases where the IID is derived 21398 from say, a short address, this bit should be forced to 0, indicating 21399 that it is locally administered. See: 21400 https://tools.ietf.org/html/rfc4291#section-2.5.1 21401 https://tools.ietf.org/html/rfc4944#section-6 21402 https://tools.ietf.org/html/rfc2464#section-4 21403 From Anthony Merlino 21404 - 6LoWPAN: IEEE802.15.4 stores and uses addresses in little endian 21405 order. From Anthony Merlino 21406 - 6LoWPAN: Address comment regarding avoiding double lookup of address 21407 context. From Anthony Merlino 21408 - 6LoWPAN: Record and restore d_buf on entry/exit of sixlowpan_input. 21409 This avoids an issue where d_buf gets set to NULL by 6LoWPAN, and 21410 then is used by forwarding logic from another network interface 21411 before getting set back to the drivers internal buffer. From Anthony 21412 Merlino 21413 - 6LoWPAN: sixlowpan_input should always return 0 if the incoming frame was 21414 consumed. From Anthony Merlino 21415 - TUN Driver: Fixes a problem reported by Masayuki Ishikwawa: Recently I 21416 noticed that ARP response packet is corrupted when I tried to run 21417 bluekitchen with the latest tun.c in TAP mode. If I revert commit 21418 8193c28e9126c9cb89042e80d6ebab7485a831e4, then it works again. From Xiang 21419 Xiao 21420 - Telnet Driver: Add missing logic to set read event flags in poll() 21421 method. From Ken Pettit 21422 21423 * Wireless/Wireless Drivers: 21424 21425 - BLE: Fix uninitialized variables. From Lwazi Dube 21426 - BLE GATT header file: Fix struct name. From Lwazi Dube 21427 - BLE GATT: Remove unnecessary GATT ioctls From Lwazi Dube 21428 21429 * Graphics/Display Drivers: 21430 21431 - ST7032: Fix seek method. Was not taking into account the offset for the 21432 SEEK_END case. Did not account for negative offsets. On errors, it was 21433 clobbering the filep->f_pos setting. From Gregory Nutt 21434 - PCF8574 Backpack: Fix seek method. Had the same problems as noted for 21435 ST7032 driver. From Gregory Nutt 21436 21437 * Common Drivers: 21438 21439 - Button Upper Half: Fix two bad NULL checks From Juha Niskanen 21440 - PWM Interface: Remove dependency on CONFIG_PWM for the upper-half 21441 PWM header. This allows compilation for the lower-level PWM drivers 21442 even if the upper-half PWM logic is not used. From Mateusz Szafoni 21443 - Various I2C Drivers: In most I2C drivers, correct upper index value 21444 in I2C trace dump. Eliminates the extra NONE event from the trace 21445 dump output. From Ouss4 21446 - Battery Gauge: Add missing initialization of semaphore. From Alan 21447 Carvalho de Assis 21448 - Batter Charger: Add missing initialization of semaphore. From Alan 21449 Carvalho de Assis 21450 - MCP73871: Fix Microchip MCP73871 Battery Charger driver to register 21451 correctly as a battery charger. The first element of a 'struct 21452 battery_charger_dev_s' should be a pointer to operations structure. From 21453 Alan Carvalho de Assis 21454 - MCP794xx: Fix MCP794xx driver to wait for OSCRUN and fix tm_year. From 21455 Abdelatif Guettouche 21456 - Numerous files: Fixes usage of CONFIG_BIG_ENDIAN; should be 21457 CONFIG_ENDIAN_BIG From Anthony Merlino 21458 21459 * ARMv7-A: 21460 21461 - ARMv7-A MMU: Fix end address calculation for mmu_invalidate_region() API 21462 From Petro Karashchenko 21463 21464 * ARMv7-M: 21465 21466 - ITM: Fix missing space causing macro issues From Alan Carvalho de 21467 Assis 21468 - Common Exception Handlers: This commit changes the lazy and non-lazy 21469 exception handler to remove a couple of cpsid instructions from them 21470 on ARMv7-m. If my understanding is correct then these interrupt 21471 manipulations aren't doing anything anyway because prioritization 21472 stops secondary interrupts arriving and, even if they did work, they 21473 would have introduced race conditions for the period of time between 21474 the interrupt arriving and further interrupts being disabled. From 21475 Dave Marples 21476 - MPU/Protected Mode Build: Revert "arch/arm/armv7-m: MPU: 21477 mpu_log2regionceil needs take into account the offset too". Masayuki 21478 Ishikawa reports that this commit breaks ALL PROTECTED mode builds. It 21479 violates the basic requirements of the use of the MPU in protected mode. 21480 Those basic requirements are: 21481 1. The MPU region must be aligned to the base address of the memory 21482 region being mapped (it may NEVER extend before the memory region). 21483 That is, the following MUST always be zero: (base & ((1 << l2size) - 1)) 21484 2. The MPU region must never extend beyond the end of the memory region. 21485 That is, the following must be true: size >= (1 << l2size) 21486 From Gregory Nutt 21487 21488 * Microchip PIC32MX Drivers: 21489 21490 - PIC32MX Ethernet: Fix a comparison in a debug assertion. Should be 21491 <= vs <. Noted by Anonymous in Bitbucket Issue 134. From Gregory Nutt 21492 21493 * Microchip PIC32MZ: 21494 21495 - PIC32MZ chip.h Header: Add a missing " in an error message. From Ouss4 21496 21497 * Microchip PIC32MZ Drivers: 21498 21499 - PIC32MZ Ethernet: Fix a comparison in a debug assertion. Should be 21500 <= vs <. Noted by Anonymous in Bitbucket Issue 134. From Gregory Nutt 21501 21502 * Microchip/Atmel SAMD21/L21 21503 21504 - SAMD21/L21: Corrects behavior of the I2C_M_NOSTART flag. Also adds 21505 a release a bus on RXNACK and corrects typo priv->flags to msg->flags 21506 as priv->flags is never set. From Alexander Vasiliev 21507 - SAMD21/L21: Fix SAMD2L2 arch to use calibrated oscillator value. Now 21508 SAMD20 and SAMD21 should work fine without external crystal. Note that 21509 SAML21 Xplained board has an external crystal and doesn't need this change, 21510 unless you don't want to use the crystal. From Alexander Vasiliev 21511 - SAMD21/L21 I2C Master: Adds calculation of a timeout and disables 21512 interrupts in case of error. From Alexander Vasiliev 21513 21514 * Microchip/Atmel SAMD21/L21 Boards 21515 21516 - SAML21-Xplained: Fix removed MAXCOARSESTEP from saml21-xplained board. 21517 From Alan Carvalho de Assis 21518 21519 * Microchip/Atmel SAMD51/Ex 21520 21521 - SAMD51/Ex: Alexander Vasiliev's fix to the SAMD21 I2C Master (commit 21522 b1110ba91c549572e94c24ebed202643233deee3) should probably also be 21523 applied to the SAMD51 I2C Master which is identical. From Gregory Nutt 21524 21525 * Microchip/Atmel SAMV7 21526 21527 - SAMV7 Serial: Fix case where TTYS0 is not defined. From Ken Pettit 21528 21529 * Maxim Integrated MAX326xx 21530 21531 - MAX326xx: WFI instruction in IDLE loop seems to interfere with 21532 stability. Commented out for now. Needs to be investigated further. 21533 From Gregory Nutt 21534 21535 * NXP i.MXRT Drivers: 21536 21537 - i.MXRT FLEXPWM: Correct duplicated definitions From David Sidrane 21538 - i.MXRT SERIAL: Fix TTYS0 defined definitions of higher numbered ports 21539 From David Sidrane 21540 - i.MXRT LPSPI: Removed unused clock, that borked the build. From David 21541 Sidrane 21542 - i.MXRT LPI2C: I2C Reset rework From David Sidrane 21543 21544 * On Semi LC823450: 21545 21546 - LC823450: Fix up_allocate_heap() in lc823450_allocateheap2.c. This 21547 change fixes heap size and also implements up_addregion(). From 21548 Masayuki Ishikawa 21549 - LC823450: Fix go_os_start() in lc823450_start.c. I found a bug in 21550 go_os_start() that it returns immediately because it does not compare 21551 r1 to zero. This commit fixes this bug. Also, this commit fixes its 21552 description. From Masayuki Ishikawa 21553 - Other Architectures: Masayuki Ishikawa's change to go_os_start() was 21554 also to all MCU-specific start-up functions that support 21555 go_os_start(). From Gregory Nutt 21556 21557 * On Semi LC823450 Boards: 21558 21559 - LC823450-XEVK: Fix IOB params in rndis/defconfig. These parameters 21560 work for HTTP audio streaming. From Masayuki Ishikawa 21561 - LC823450-XGEVK: Change RNDIS MAC address assignment in rndis 21562 configuration. In previous implementation, mac[0] was assigned to 21563 0xaa for RNDIS host to avoid MAC address conflicts with RNDIS 21564 device.. However, I noticed that this assignment causes a random MAC 21565 address generation on ubuntu16.04 or later which is inconvenient to 21566 set up network interface. This new assignment scheme fixes this 21567 issue. From Masayuki Ishikawa 21568 - LC823450-XGEVK: Fix overlapped memory settings in memory.ld.

In previous implementation, mac[0] was assigned to 21631 0xaa for RNDIS host to avoid MAC address conflicts with RNDIS 21632 device.. However, I noticed that this assignment causes a random MAC 21633 address generation on ubuntu16.04 or later which is inconvenient to 21634 set up network interface. This new assignment scheme fixes this 21635 issue. From Masayuki Ishikawa 21636 21637 * TI Tiva: 21638 21639 - Tiva LM/TM4C Start-Up: Remove option CONFIG_TIVA_BOARD_CLOCKCONFIG. It is 21640 not used and unnecessary. Fix some naming. up_clockconfig() is 21641 inappropriate. Change tiva_clockconfig() to tiva_clock_reconfigure() 21642 then we can change up_clockconfig() to tive_clock_configure(). From 21643 Gregory Nutt 21644 - Tiva LM/TM4C GPIO Interrupts: Fix tiva gpio interrupts From Lwazi Dube 21645 - Tiva LM/TM4C: Improve GPIO interrupt support by removing unnecessary, 21646 hard-coded per-MCU defines and using the existing Kconfig configuration 21647 options instead. From Lwazi Dube 21648 21649 * TI Tiva Drivers: 21650 21651 - Tiva TM4C Serial: After commit 21652 51b78034ac8d1fdf598107bf4093f0beccd5b80b, my tiva console does not 21653 work - enter key produces garbage characters. This commit fixes the 21654 problem for me. From Lwazi Dube 21655 21656 * C Library/Header Files: 21657 21658 - include/dsp.h: Fix missing semicolon error in dsp.h From MYAPICI 21659 - include/nuttx/compiler.h: Correct support of C-version-specific features. 21660 Cannot depend on GCC version because -std=c89 may be used on comomand 21661 line. Need instead to use __STDC_VERSION__ to determine if a feature is 21662 supported. Also add conditional support inline, depending on C99. From 21663 Gregory Nutt 21664 - libs/libc/stdio: fread() should always set EOF if fewer than the 21665 requested number of bytes was not read. Per Anthony Merlino. From 21666 Gregory Nutt 21667 21668 * Build System: 21669 21670 - sched/irq/Make.defs: Fix warning about irq_csection.o appearing 21671 multiple times in the same rule. From Gregory Nutt 21672 21673 * Tools: 21674 21675 - tools/gencromfs.c: "gencromfs.c:1171:3: warning: ignoring return 21676 value of 'asprintf'", declared with attribute warn_unused_result 21677 [-Wunused-result]. From David Sidrane 21678 - tools/gencromfs.c: Fix build on macOS. From David Sidrane 21679 21680 * NSH Library: apps/nshlib: 21681 21682 - apps/nshlib: Fixes an error in the NSH parser. There was a bug when 21683 executing an nsh shell script which contains a redirection. When the 21684 command in the script is executed, it sets the vtbl->np.np_redirect flag 21685 (as it should), but then doesn't restore it, leaving it set at the end of 21686 the script execution. Then the vtbl->np.np_redirect flag is set when the 21687 'sh' command completes, causing a restore from un-initialized variables, 21688 thus leading to a crash. See the code snippet below for an example test 21689 case. 21690 21691 Test case: 21692 21693 NuttShell (NSH) 21694 nsh> mkrd -s 1024 40 21695 nsh> mkfatfs /dev/ram0 21696 nsh> mount -t vfat /dev/ram0 /tmp 21697 nsh> echo "echo 1 > /dev/null" > /tmp/test.sh 21698 nsh> cat /tmp/test.sh 21699 echo 1 > /dev/null 21700 nsh> sh /tmp/test.sh 21701 ... 21702 21703 The nsh prompt doesn't get printed. You can type a couple of commands, 21704 but then the system will crash because of bad pointers. From Ken Pettit 21705 - apps/nshlib: Fix buffer overrun when redirected to a file. SAVE_SIZE 21706 must be the same as sizeof(struct serialsave_s). From Masayuki Ishikawa 21707 21708 * System Utilities: apps/system: 21709 21710 - system/system.c: Fixes build error; There is no result variable, use 21711 errcode instead. From Anthony Merlino 21712 - apps/system/vi: Bug fixes: 21713 1. Deletion of last line in file using 'dd' caused infinite loop 21714 searching for 'nextline'. Fixed. 21715 2. Insertion of line above 1st line using 'O' caused line to be 21716 inserted on 2nd line. Fixed. 21717 3. Paste buffer from 'dd' was being free'd after the 'p'aste operation, 21718 preventing multiple paste opportunity. Fixed. 21719 4. The cursor was not being bound to the line end and was allowed to 21720 'hover' over the '\n' EOL character. This caused wierd (relative to 21721 standard vi) insertion locations and cursor movement with 'a'ppend 21722 and 'i'nsert. Fixed. 21723 5. The 'vi_shrinkpos' position didn't take the end of file pointer into 21724 account when calculating 'curpos', 'prevpos' variables causing 21725 wierdness when deleting things near the end of the file. Fixed. 21726 6. The 'yy'ank command was improperly deleting the text from the 21727 document instead of simply yanking to the paste buffer. Fixed. 21728 7. The 'dd'elete line funciton was not copying the deleted line to the 21729 paste buffer as part of the delete operation. Fixed. 21730 8. The bottom line of the screen was sometimes being used for document 21731 text and other times for command / find entry. Fixed by reserving 21732 the bottom the bottom line for status / command only. 21733 9. When scrolling up / down through a file, the cursor position was not 21734 preserved and moved further and further to the left column based on 21735 the line lengths of the lines visited. Fixed. 21736 10. The display was being COMPLETELY redrawn with each keystroke, 21737 causing the responsiveness to be unbearable. Fixed. Added logic to 21738 dynamicall indicated which portions of the screen need to be updated 21739 (full display, current line to end of screen, current line only, 21740 none). 21741 11. The individual display line updates were being performed a character 21742 at a time by calling the vi_putch() function, causing slow 21743 performance, especially in telnet or USBCDC sessions where there is 21744 a lot of overhead per packet. Fixed by calling vi_write() instead 21745 with a block of characters with breaks as needed for TAB exansion. 21746 12. The forward delete 'x' operation allowed deletion through '\n' 21747 characters causing lines to be joined. This is different from 21748 standard vi where 'x' at the end of a line performs a delete 21749 backward operation. Fixed. 21750 13. When in 'ex' or find sub-modes (':' or '/' bottom line modes), 21751 hitting backspace with empty text did not return the operation to 21752 command mode like it does in standard vi. Fixed. 21753 14. Performing a 'find' opertation would only search from the current 21754 cursor position to the end of the file and did not wrap like in 21755 standard vi. Fixed. 21756 15. Loading a file that was larger than the initial text allocation 21757 would force a call to 'vi_extendtext', marking the file as modified 21758 when in fact it hadn't even been loaded yet. Fixed. 21759 16. Combined vi_insert_mode and vi_replace_mode into a single function 21760 to save code space since they are nearly identical routines. 21761 17. In command mode, backspace was deleting characters which is 21762 different from standard vi. Backspace in command mode normally 21763 simply moves the cursor left / to the previous line. Fixed. 21764 18. Added code to handle boundry conditions when the file is new and 21765 commands are applied to an empty file. 21766 19. Fixed vi_shrinktext so it doesn't allocate a zero-length buffer when 21767 the last character in the file is deleted. 21768 20. The 'x' command was not copying to the paste buffer. Fixed. 21769 21. Fixed parsecolon routine to properly deal with ":wq" command sequence. 21770 From Ken Pettit 21771 21772 * Wireless Utilities: apps/wireless: 21773 21774 - apps/wireless/bluetooth/btsak: 'bt bnep0 info' outputs a reversed addr. It 21775 should print BDAddr: aa:bb:cc:dd:ee:ff instead of BDAddr: 21776 ff:ee:dd:cc:bb:aa. From Lwazi 21777 - apps/wireless/bluetooth/btsak: Fix some errors in btsak.

Re-sets daemon_shutdown so 21786 that a subsequent daemon launch does not immediately return. From Anthony 21787 Merlino 21788 21789NuttX-7.29 Release Notes 21790------------------------ 21791 21792The 129th release of NuttX, Version 7.29, was made on March 25, 2019, 21793and is available for download from the Bitbucket.org website. Note 21794that release consists of two tarballs: nuttx-7.29.tar.gz and 21795apps-7.29.tar.gz. These are available from: 21796 21797 https://bitbucket.org/nuttx/nuttx/downloads 21798 https://bitbucket.org/nuttx/apps/downloads 21799 21800Both may be needed (see the top-level nuttx/README.txt file for build 21801information). 21802 21803Additional new features and extended functionality: 21804 21805 * Core OS: 21806 21807 - Configuration: CONFIG_NFILE_DESCRIPTORS=0 can no longer be used to 21808 disable the file system. NuttX with no file system does not make 21809 sense and is no longer supported. From Gregory Nutt. 21810 - Rename most internal OS functions from sched_* to nxsched_* to 21811 indicate that they are NuttX internal functions (some renaming is 21812 still needed). From Gregory Nutt. 21813 - Rename all internal OS functions from task_* to nxtask_* to indicate 21814 that they are NuttX internal functions. From Gregory Nutt. 21815 - Rename sched_process_timer to nxsched_process_timer. Rename 21816 sched_timer_expiration to nxsched_timer_expiration. Rename 21817 sched_alarm_expiration to nxsched_alarm_expiration. Those are the 21818 appropriate names for an internal sched/ function (still many named 21819 incorrectly). From Gregory Nutt. 21820 - Standardize naming: Rename os_start() to nx_start(), rename os_smp* 21821 to nx_smp*, rename os_bringup to nx_bringup, rename all internal 21822 static functions to begin with nx_ vs os_. From Gregory Nutt. 21823 - Initialization: Remove the option CONFIG_BOARD_INITTHREAD. Now, if 21824 CONFIG_BOARD_INITIALIZE is selected, then the board_initialize() 21825 logic will ALWAYS run on an internal kernel thread. This will 21826 prevent the problems people have had doing inappropriate 21827 board_initialization on the IDLE thread. From Gregory Nutt. 21828 - Initialization: Add support for CONFIG_BOARD_EARLY_INITIALIZE. If 21829 this option is selected then nx_start() will call a board-provided 21830 function board_early_initialize() immediately after calling 21831 up_initialize(). Rename board_initialize() to 21832 board_late_initialize(). From Gregory Nutt. 21833 - Signal Delivery: Add a flag to the TCB to indicate that we are in a 21834 signal handler. Use this flag to assure that a there is never 21835 attempts to nest signal handling operations on a thread. This was 21836 guaranteed before but when locking of pre-emption during signal 21837 delivering was eliminated in a previous commit, there was a remote 21838 possibility of an attempt to do nested signal handling. This flag 21839 assures that there is only one signal handled at a time. From 21840 Gregory Nutt. 21841 - Signal Handler Security: The architecture-specific signal handler 21842 return register state is saved and available on the user stack. 21843 This commit reorders some logic so that certain, critical registers 21844 are preserved in the TCB. This eliminates most malicious exploits 21845 which more the return address, for example, but does not make the 21846 logic 100% secure. From Gregory Nutt. 21847 - Timer Interrupt Procssing: Add a configurable call out to a 21848 user-provided function, 'timer hook', on each timer interrupt. From 21849 Gregory Nutt. 21850 - PM Activity: Add pm_staycount() API for get stay numbers. This 21851 function is currently not used and a waste of FLASH space. From ligd. 21852 - Pthreads: Add support for pthread_mutex_timedlock From Leif Jakob. 21853 - Pthread Spinlocks: Add a very preliminary implementation of the new 21854 POSIX pthread_spinlock_* interfaces. From Gregory Nutt. 21855 - Critical Section Monitor: Remove SCHED_IRQMONITOR_GETTIME to 21856 simplify the clock source selection: (1) Use up_critmon_gettime if 21857 SCHED_IRQMONITOR, (2) Call clock_systimespec if SCHED_TICKLESS, (3) 21858 Don't collect timing info for all other cases. From Xiang Xiao. 21859 - Work Queue Notification: Notifier can now work with either lpwork 21860 or hpwork. From Xiang Xiao. 21861 - Protected Build: Add add a new field (us_heapend) to struct 21862 userspace_s that labels the end of the heap. From Xiang Xiao. 21863 21864 * Binary Loader/Kernal Modules/Shared Libraries 21865 21866 - Shared Libraries: Implement dlerror() using strerror(). From Xiang 21867 Xiao. 21868 - Shared Libraries: Add LD_LIBRARY_PATH environment variable 21869 support. From anchao. 21870 - ELF Loaders: Optimize elf load speed: (1) Don't zero out memory, 21871 (2) Reduce the initial buffer size to 32 bytes. From Xiang Xiao. 21872 - ARM ELF Relocation: Add support for the R_ARM_THM_JUMP11 relocation 21873 type. This relocation type may be generated when LTO optimization 21874 is enabled. From anchao. 21875 - ELF Modules: Add relocation buffer table to reduce filesystem 21876 access. From anchao. 21877 - ELF Modules: Add symbol buffer table to reduce filesystem access. 21878 From anchao. 21879 21880 * File Systems/Block and MTD Drivers 21881 21882 - Filesystem Mount: Move the union inode_ops_u i_mtd field into the 21883 mount section of inode_ops_u and remove the guard to simplify fs 21884 which support both block and mtd. From Xiang Xiao. 21885 - ROMFS: Add support to mount a ROMFS volume using an MTD driver 21886 interface using the standard mount() operation. From Xiang Xiao. 21887 - LittleFS: VFS wrapper improvement: (1) Support block device 21888 interface, (2) support ioctl, stat and sync file operation, (3) 21889 support forceformat and autoformat option, (4) update file->f_pos 21890 and dir->fd_position, (5) remove the internal struct from dir, and 21891 (6) remove mtd byte read/write requirement. From Xiang Xiao. 21892 - UnionFS: Support mount of UnionFS from the NSH command line. From 21893 Xiang Xiao. 21894 21895 * Networking/Network Drivers: 21896 21897 - UsrSock: Add mutual exclusion so that only user can perform a 21898 socket request From zhangyuan7. 21899 - UDP: Initialize callback address structure to avoid random values 21900 in padding. From anchao. 21901 21902 * Wireless/Wireless Drivers: 21903 21904 - SX127x: Initial support for SX127x LoRA radio From Mateusz Szafoni. 21905 21906 * Graphics/Display Drivers: 21907 21908 - Graphics: Fix a naming collision: Ye olde nx_start that started 21909 the NX graphics is now nxmu_start(). nxmu_start() is now 21910 prototyped in nxmu.h (instead of nx.h). From Gregory Nutt. 21911 - NX Server Startup: Extend nxmu_start() so that receives a display 21912 number as an argument. This makes it possible to have multiple 21913 instances of the NX server running on boards that support multiple 21914 displays. Also includes updates to boardctl() to accept display 21915 number paramters. From Gregory Nutt. 21916 - Graphics: nx_openwindow() and nxtk_openwindow() now accept an 21917 additional 'flag' parameter. This argument is current used only to 21918 select a RAM backed, per-window framebuffer. From Gregory Nutt. 21919 - Per-Window Framebuffers: Windows may now be optionally created 21920 with a RAM frambuffer backing up the window content. Rending into 21921 the window will result in rending into the backup framebuffer, then 21922 updating the physical display from the framebuffer. The advantage 21923 of this option is that the application that manages window will no 21924 longer receive redraw() callbacks. Those calls normally occur when 21925 a window "above" moves exposing a portion of the window below. If 21926 this option is selected, then the system will redraw the exposed 21927 portion of the window from the backup framebuffer without 21928 intervention of the window applications. This greatly reduces the 21929 complexity of the application and performance of the window at the 21930 expense of increased memory usage. Redraw requests in other cases 21931 are also suppressed: Changes to window position, size, etc. As a 21932 consequence, some manual updates will be required when certain 21933 events occurr (like removing a toolbar from a window). NOTE: A 21934 significant amount of RAM, usually external SDRAM, may be required 21935 to use per-window framebuffers. 21936 21937 * Other Common Device Drivers: 21938 21939 - Driver Notifications: Support signal notification through 21940 SIGEV_THREAD in all drivers that provide signal notifications: 21941 RTC, Joysticsks, buttons, Zero-Crossing, wireless, FT80x, Timer, 21942 PHY. From Xiang Xiao. 21943 - Watchdog Driver: Support auto-monitor service From Gregory Nutt. 21944 - Timer and Alarm Drivers: Implement up_critmon_gettime and 21945 up_critmon_convert and remove the critical section from 21946 current_usec to infinite recursion. From Xiang Xiao. 21947 - RTC Driver: Protect the RTC state with a semaphore. From Xiang 21948 Xiao. 21949 - Serial Upper Half: Call pm_activity() when characters are received 21950 on a console device. From Gregory Nutt. 21951 - MPU60x0: Initial support for TDK InvenSense MPU6000 and MPU6050 21952 6-axis gyroscope and accelerometers. This commit supports SPI 21953 media only.

From Valmantas Paliksa. 21958 - MCP2515: Add MCP2515 clock input config to KConfig. From 21959 Valmantas Paliksa. 21960 - MAX7456: Support for the Maxim MAX7456 on-screen-display chip. 21961 From Bill Gatliff. 21962 21963 * Common Board Logic: 21964 21965 - boardctl(): up_testset() can now be accessed by applications via 21966 the boardctl() interface rather than attempting to call it 21967 directly. pthread Spinlocks are not available unless the 21968 architecture supports the up_testset() operation. From Gregory 21969 Nutt. 21970 - boardctl(): Add support for BOARDIOC_NXTERM which can be used to 21971 create an NxTerm terminal. From Gregory Nutt. 21972 - boardctl(): Add boardctl() commands to replace direct calls to 21973 nxterm_redraw() and nxterm_kbdin(). From Gregory Nutt. 21974 21975 * Microchip PIC32MZ Drivers: 21976 21977 - PIC32MZ Timers: Add support for the PIC32MZ timers (driver, 21978 lowerhalf, freerun and oneshot) From Abdelatif Guettouche. 21979 21980 * Common ARM Options: 21981 21982 - arch/arm: Move FPU options to a common place and unify the usage 21983 by removing ARCH_CORTEXRxF. From Xiang Xiao. 21984 - arch/: Unify the cache interface for all architectures that 21985 support a data cache. From Xiang Xiao. 21986 - ARMv7-M/A/R: Add a architecture-specific new barriers.h header 21987 file that provides the memory barrier definitions that were 21988 previously in the (now unified) cache.h header files. From Gregory 21989 Nutt. 21990 21991 * ARMv7-A 21992 21993 - ARMv7-A: Support thumb mode and fix interworking issue. From 21994 zhangyuan7. 21995 - ARMv7-A: Add weak attribute to arm_data_initialize so platform 21996 could provide the new implementation as needed. From zhangyuan7. 21997 - ARMv7-A: Add SCR bit definitions. From Xiang Xiao. 21998 - ARMv7-A: Add mmu_l1_map_regions() to remove the code duplication. 21999 From Xiang Xiao. 22000 - ARMv7-A: Add the initial cortex-a7 architecture support From 22001 zhangyuan7. 22002 22003 * ARMv7-M 22004 22005 - ARMv7-M: stackcheck allow faulting stack calculation to make it to 22006 the up_assert reg dump From David Sidrane. 22007 22008 * Microchip/Atmel SAMD21/L21 Drivers: 22009 22010 - SAMD2/L2: Add RS485 support to SAMD2L2 serial. From Alan Carvalho 22011 de Assis. 22012 22013 * Misoc: 22014 22015 - Minerva: Add support for the Minerva architecture. From Ramtin 22016 Amin. 22017 22018 * Misoc Boards: 22019 22020 - misoc: Add support for an NSH configuration using the Verilator 22021 board.

From Mateusz Szafoni. 22133 - OmnibusF4: Initial support for the OmnibusF4 family of flight 22134 management units. "OmnibusF4" is not a product name per se, but 22135 rather a design spec that many product vendors adhere to. The spec 22136 defines the major components, and how those components are wired 22137 into the microcontroller. Airbot is one such vendor, and they 22138 publish a schematic here: http://bit.ly/obf4pro. Other software 22139 that supports the OmnibusF4 family include Betaflight, iNAV, and 22140 many others. PX4 recently added support as well, using their own, 22141 non-upstreamed, bespoke port of NuttX. No code from those resources 22142 is included in this port. From Bill Gatliff. 22143 - OmnibusF4: Add MAX7546 support. From Bill Gatliff. 22144 22145 * TI CCxx: 22146 22147 - CC1312R1: Code complete and builds successfully. Stalled on 22148 further radio development. I planned to integrate the IEEE 802.15.4 22149 radio interface, but the Cortex-M0 interface is not available with 22150 an open license. 22151 22152 * TI CCxx Boards: 22153 22154 - LaunchXL-CC1312R1: Add support for on-board LEDs and buttons. The 22155 LauchXL-CC1312R1 NSH Configuration is now fully functional. From 22156 Gregory Nutt. 22157 - LaunchXL-CC1310: Clone LED and button support from the 22158 LaunchXL-CC1312R1. The number of LEDs and buttons as well as DIO 22159 usage is identical (Still not functional). From Gregory Nutt. 22160 22161 * Tools: 22162 22163 - tools/rmcr.c: Add a tool to remove carriage returns and dangline 22164 whitespace at the end of lines. From Gregory Nutt. 22165 - tools/nxstyle.c: Can now detect if the C comment closing is not on 22166 a separate line. From Gregory Nutt. 22167 - tools/nxstyle.c: Make sure that all files begin with a comment on 22168 line 1 (which should be the file header). From Gregory Nutt. 22169 - tools/nxstyle.c: Add check for multiple definitions of local 22170 variables on a line. From Gregory Nutt. 22171 - tools/nxstyle.c: Beef up logic that detects multiple variable 22172 definitions per line. From Gregory Nutt. 22173 - tools/nxstyle.c: Add capability to detect CamelCase identifiers. 22174 From Gregory Nutt. 22175 - tools/nxstyle.c: Add logic to detect a blank line following a left 22176 brace or a blank line preceding a right brace. From Gregory Nutt. 22177 - tools/nxstyle.c: Don't complain about certain lowercase characters 22178 in otherwise uppercase pre-processor identifers: IPv6, IPv4, 22179 ICMPv6, IGMPv2, p as a decimal point, d signifying a divisor. It 22180 was a bad idea to let the door open a crack for there. While they 22181 improve readability, the inconsistently also causes other 22182 problems. From Gregory Nutt. 22183 22184 * Build System: 22185 22186 - Makefiles: Modify tools/Makefiles to add a "Do not Edit" warning 22187 on defconfig files From Alan Carvalho de Assis. 22188 22189 * Libraries/Header Files: 22190 22191 - lib_vsprintf() (Nano): Add newlib-nano lib_vsfprintf has been 22192 added and is now the default support for the printf family. This 22193 fprintf code was originally adapted from AVR libc and provides 22194 improved floating point output support, including 'g' mode and 22195 making 'f' mode include digits past the decimal by default. The 22196 newlib version can be found here: 22197 https://salsa.debian.org/electronics-team/toolchains/newlib-nano. 22198 That project is GPL overall, but the newlib-nano printf portions 22199 are BSD licensed as described in the COPYING.NEWLIB file. From 22200 Keith Packard. 22201 - lib_vsprintf() (Nano): Added support for long lont types. From 22202 Johannes. 22203 - lib_vsprintf() (Nano): Added hh type modifier (without extending 22204 the flag variable). From Johannes. 22205 - lib_vsprintf() (Nano): Adds configurable support for numbered 22206 arguments. From Johannes. 22207 - lib_vsprintf() (Nano): Cleaned naming and allow for leading zeros 22208 in argument number (which doesn't make sense but should be). From Johannes. 22209 - lib_vsprintf() (Legacy): Add support for %g format which, for 22210 these purpose, is equivalent to %f except that trailing zeroes are 22211 suppressed. From Gregory Nutt. 22212 - vscanf(): Moved vscanf logic to lib_sscanf.c Switched to stream 22213 interface (tricky, because the old implementation used massive read 22214 ahead, which isn't suitable for streams, chars already read are 22215 gone). Added hh, h, and ll modifiers. From Johannes. 22216 - scanf() and fscanf(): Added scanf and fscanf based on enhanced 22217 vscanf(). From Johannes. 22218 - uname(): Add build date and time to uname output (like Linux). 22219 From Gregory Nutt. 22220 - strsep(): Add strsep BSD/Linux function. From Xiang Xiao. 22221 - netdb: Hostname support no longer depends on CONFIG_NET since the 22222 host name is also useful in the non-network environment. 22223 CONFIG_NET_HOSTNAME changed to CONFIG_LIB_HOSTNAME. From Xiang Xiao. 22224 - netdb: Support the nameserver change notification then we can pass 22225 DNS info from server to client in usrsock case. From Xiang Xiao. 22226 - include/fixedmath.h: Add macros for conversion between types 22227 b16_t and type double From Gregory Nutt. 22228 - include/limits.h: Define NL_ARGMAX (as well as some of the other 22229 'invariant values' per 22230 http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html). 22231 From Johannes. 22232 - linclude/limits.h: Add 'range 9 999999' to CONFIG_LIBC_NL_ARGMAX 22233 to Kconfig. Per OpenGroup.org, the minimum value for NL_ARGMAX is 22234 9. From Gregory Nutt. 22235 - include/nuttx/lcd/edid.h: Add extended EDID block IDs From 22236 Gregory Nutt. 22237 22238 * apps/ General: 22239 22240 - apps/: Follow up the kernel signal-related change in various files 22241 under examples/ and graphics/. From Xiang Xiao. 22242 - apps/: Update for corrected name of standard header file. Should 22243 be dlfcn.h, not dllfcn.h. From Gregory Nutt. 22244 - apps/: The file system can no longer be disabled. Remove all 22245 conditional logic based on CONFIG_NFILE_DESCRIPTORS==0 From 22246 Gregory Nutt. 22247 - apps/: Remove/replace all conditional logic based on 22248 CONFIG_NSOCKET_DESCRIPTORS == 0. That value is always greater than 22249 zero now. In places just replace with #ifdef CONFIG_NET. From 22250 Gregory Nutt. 22251 - apps/: Some updates due to NuttX renaming: 22252 CONFIG_BOARD_INITIALIZE is now CONFIG_BOARD_LATE_INITIALIZE; 22253 board_initialize() is now board_late_initialize(). From Gregory 22254 Nutt. 22255 - apps/: Graphics interfaces nx_openwindow() and nxtk_openwindow() 22256 now accept an additional 'flag' parameter. From Gregory Nutt. 22257 22258 * NSH: apps/nshlib: 22259 22260 - apps/nshlib/nsh_netinit.c: Update for changes to signal 22261 notification structures. From Gregory Nutt. 22262 22263 * Examples/Tests: apps/examples: 22264 22265 - apps/examples/ini_dumper: New example program. ini_dumper is 22266 example program that dumps content of ini file in pretty ascii table. 22267 It is using inih ini library in fsutils/inih. From Michal Lyszczek. 22268 - apps/examples/modbusmaster: Add Simple Modbus master example. 22269 This example only supports Read/Write HoldingRegisters, but it is 22270 easy to extend it to support Read/Write Input/Coils/etc. 22271 Originally creatd by Vytautas in 2016 and updated with minor fixes 22272 for this commit. From Alan Carvalho de Assis. 22273 - apps/examples/pwfb: Added a test/example at apps/examples/pwfb 22274 that was used for initial testing of the per-window framebuffer 22275 feature. From Gregory Nutt. 22276 - apps/examples/pwlines: Added another a test/example at 22277 apps/examples/pwlines that was used for further testing of the 22278 per-window framebuffer feature. From Gregory Nutt. 22279 - apps/examples/sx127x: Add sx127x demo From Mateusz Szafoni. 22280 22281 * File System Utilities: apps/system 22282 22283 - apps/fsutils/inih: New package. inih (INI Not Invented Here) is a 22284 simple .INI file parser written in C. 22285 https://github.com/benhoyt/inih. From Michal Lyszczek. 22286 22287 * Network Utilities: apps/netutils: 22288 22289 - apps/netutils/codecs/: Remove the big Base64 stack array. From 22290 Xiang Xiao. 22291 - apps/netutils/codecs/: Add base64_[de|en]code_length() API From 22292 ligd. 22293 22294 * System Utilities: apps/system 22295 22296 - apps/system/cfgdata: Make builtin task stack size and priority 22297 configurable. Set default to 2048 (from 1024) per recommendation 22298 of Ken Pettit. From Gregory Nutt. 22299 - apps/system/embedlog: Update to version 0.4.0. From Michal Lyszczek. 22300 - apps/system/nxplayer and nxrecorder: Change 'int prio' to 22301 'unsigned int prio'. Required by changes to MQ function 22302 prototypes. From Michal Lyszczek. 22303 - apps/system/psmq: New package. psmq is publish subscribe message 22304 queue. It's a set of programs and libraries to implement 22305 publish/subscribe way of inter-process communication on top of 22306 POSIX message queue. From Michal Lyszczek. 22307 - apps/system/zmodem: Switch to the raw mode before transfer and 22308 restore to the original setting after finishing the transfer. From 22309 Xiang Xiao. 22310 22311 * Testing: apps/testing: 22312 22313 - apps/testing/: Move all file system tests from examples/ to 22314 testing/ (cxxtest, fstest, nxffs, smart, smart_test, smp). From 22315 Gregory Nutt. 22316 - apps/testing/cxxtest: Add a README file. From Gregory Nutt. 22317 - apps/testing/ostest: Add test of pthread_mutex_timedlock() From 22318 Gregory Nutt. 22319 - apps/testing/ostest: Fix several errors in the setvbuf() test. 22320 From Gregory Nutt. 22321 - apps/testing/scanftest: Port of Greg King's scanf test 22322 (https://github.com/cc65).

Only the most critical bugfixes are listed here (see the 22330ChangeLog for the complete list of bugfixes and for additional, more 22331detailed bugfix information): 22332 22333 * Core OS: 22334 22335 - Signals: Restructure nxsig_deliver() so that the signal handler is 22336 not called with the pre-emption disabled (or, at least no with 22337 pre-emption disabled by nxsig_deliver() itself). From Gregory Nutt. 22338 - Critical Section Monitor: Move up_critmon_* to arch.h avoid the 22339 duplicated declaration. From Xiang Xiao. 22340 - Assertions: Architecture-specific assertion logic should dump CPU0 22341 IDLE stack only when PID equals 0. IDLE threads of other CPUs do 22342 not need this special check. From Xiang Xiao. 22343 - Message Queues: Change 'int prio' to 'unsigned int prio'. 22344 According to open group specification, priority field in mq_* 22345 functions should have unsigned type: 22346 http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/mqueue.h.html. 22347 From Michal Lyszczek. 22348 - Timer Expiration: Fix macro SEC2TICK() 32-bits overflow by using 22349 uint64_t in calculation. From ligd. 22350 - Kernel Memory Manager: In mm/kmm_heap/kmm_kernel.c, remove unused, 22351 duplicated kmm_heapmember(). From Xiang Xiao. 22352 - User Memory Manager: Ensure all user allocation try sbrk before 22353 fail From Xiang Xiao. 22354 - waitid(): Could exit without leaving critical section on some 22355 error conditions. From Gregory Nutt. 22356 - IOBs: iob_allocwait() should decrease semcount manually. From 22357 Xiang Xiao. 22358 - IOBs: iob_copyin() should wait for each buffer and adjust the 22359 return value of iob_copyin_internal return to simplify the code 22360 From Xiang Xiao. 22361 - IOB Notifier: Don't check iob_navail in iob_notifier_setup to 22362 avoid a potential race condition. From Xiang Xiao. 22363 - IOB Debug Dump: Format the whole line before log to avoid the 22364 multiple timestamp prefix in each line. From Xiang Xiao. 22365 - SHM: Convert bytes to pages by MM_NPAGES instead of MM_PGALIGNUP 22366 From Xiang Xiao. 22367 - SHM: shmget() should hould call shm_extend() to allocate the 22368 physical memory. From Xiang Xiao. 22369 - Page Allocator: mm/pgalloc: shouldn't just allocate one page 22370 always. From Xiang Xiao. 22371 - Granule Allocator: Fix the wrong data in g_1bit_info and make the 22372 internal function static. From Xiang Xiao. 22373 - srbk(): Fix a backward conditional test. Should call 22374 mm_initialize() when brkaddr equal zero From Xiang Xiao. 22375 - sbrk(): Pass ARCH_HEAP_VEND as maxbreak argument From Xiang Xiao. 22376 - ELF Headers: Move elf related arch function to include/nuttx/elf.h 22377 because the implementation is located in libs/libc/machine and in 22378 order to avoid the conflict with the 3rd party libraries and clean 22379 up the file inclusion: (1) Remove redundant elf32.h, (2) Remove 22380 nuttx/binfmt/elf.h in libs/libc/machine, (2) Remove 22381 nuttx/binfmt/elf.h in modlib, and (4) Rmove nuttx/module.h in 22382 modlib. From Xiang Xiao. 22383 - ELF Executables: If there is an address environment 22384 (CONFIG_ARCH_ADDRENV), binfmt/elf doesn't need to free ctor/dtor 22385 alloc since freeing the address environment releases the heap 22386 automatically. From Xiang Xiao. 22387 - ELF Configuration: Correct libcxx exception handling by 22388 introducing the generic config(CXX_EXCEPTION and CXX_LIBSUPCXX) 22389 From Xiang Xiao. 22390 - ELF Loaders: Call umm_initialize as soon as possible otherwise 22391 elf_loadctors/elf_loaddtors may fail to allocate memory. From 22392 Xiang Xiao. 22393 22394 * Crypto: 22395 22396 - Crypto AES: After NuttX 7.28 crypto/aes.c would no longer 22397 compile. From Gregory Nutt. 22398 22399 * File System/Block and MTD Drivers: 22400 22401 - open(): Fix not returning failure for block_proxy() call. From 22402 David Sidrane. 22403 - AIO: aio_cancel() needs to signal caller after success. Also fix 22404 minor issue in the error handler. From Xiang Xiao. 22405 - HostFS: Remove the unnecessary use of host_stat() in 22406 hostfs_bind() From ligd. 22407 - LittleFS: Fix a minor issue found in code review: (1) Replace 22408 printf to finfo/fwarn/ferr, (2) Replace malloc/free to 22409 kmm_malloc/kmm_free, (3) define LFS_NAME_MAX to NAME_MAX, (4) Check 22410 the big endian using CONFIG_ENDIAN_BIG. From Xiang Xiao. 22411 - LittleFS: VFS Lookahead should use bit unit not byte unit. From 22412 Xiang Xiao. 22413 - NxFLAT: Correct a double free debug assertion. This occurs when 22414 groups are enabled: (1) once via binfmt_exit and unload_module, 22415 and (2) once via sched_releasetcb(). this was corrected by adding 22416 logic to free/unload the memory once and nullify the pointer so 22417 that cannot be freed a second time. This commit resolves Bitbucket 22418 issue #145. From Valmantas Palik�a. 22419 - NxFLAT: File descriptor leaks when nxflat loading fails. From 22420 Valmantas Palik�a. 22421 - ProcFS: Fix typo in procfs uptime logic. From Sebastien Lorquet. 22422 22423 * Networking/Network Drivers: 22424 22425 - Network Configuration: The setup seems to support a network 22426 without sockets (CONFIG_NSOCKET_DESCRIPTORS == 0). That is not the 22427 case; if the network is enabled, sockets must be provided. From 22428 Gregory Nutt. 22429 - Networking: The value ERROR should never be returned from internal 22430 OS functions. That is reserved for returning values to appliations 22431 with the errno value set. Within the OS, errors are returned with 22432 a negated errno value ALWAYS. From Gregory Nutt. 22433 - Networking: The struct in_addr doesn't have the member sin_addr. 22434 The function lib_lo_ipv6match() is for IPv6. Correct the function 22435 it calls from lib_lo_ipv4matchto() to lib_lo_ipv6match(). Also add 22436 CONFIG_NET_IPv6 for configuration. From Kejun ZHOU. 22437 - TCP (buffered) send: Fix assertion crash when window size is 22438 zero. From Gregory Nutt. 22439 - ICMP/ICMPv6: Bind icmp callback from device to connection. 22440 Resolves the issue that bind() could not be called before send() 22441 From anchao. 22442 - TUN/TAP Driver: Re-order all TUN/TAP driver state data. Not only 22443 was was with wasting memory due to alignement requirements, it was 22444 also causing network packet buffers to be improperly aligned 22445 causing problems because the network requires 16-bit packet buffer 22446 alignment for uint16_t accesses. This alignment problem was 22447 discovered by Alan Carvalho de Assis. From Gregory Nutt. 22448 - TUN/TAP Driver: Packet buffer size should include the configured 22449 GUARD_SIZE. And, given how the buffers are allocated, the 22450 allocation size must be an even number of 16-bit values to preserve 22451 alignment. From Gregory Nutt. 22452 - Local Sockets: In local_connect(), initialize lc_result before 22453 giving lc_waitsem From zhangyuan7. 22454 - Local Sockets: Fixed deadlock issue by replacing nxsem_wait() with 22455 net_lockedwait() so that we do not wait with the network locked. 22456 From zhangyuan7. 22457 22458 * Graphics/Display Drivers: 22459 22460 - NX Graphics: Remove naming associated with the now non-existent 22461 NXFE graphics layer: Rename nxfe_reportposition to 22462 nxmu_reportposition. Rename nxfe_redrawreq to nxmu_redrawreq. 22463 Rename nxfe.h to nxmu.h. Rename nxfe_state_s to nxmu_state_s. 22464 Rename nxfe_conn_s to nxmu_conn_s. From Gregory Nutt. 22465 - NxTERM: Remove the nxterm_unregister interface. The correct way 22466 to unregister a device is to unlink it. From Gregory Nutt. 22467 - NxTerm: Needs to clear display initially. Otherwise, garbage from 22468 previous display may still be present from preceding NxWM window. 22469 From Gregory Nutt. 22470 - Font Cache: Fix a memory leak in the font cache. With a busy 22471 NxTerm display, this could drain off all the memory pretty quickly! 22472 From Gregory Nutt. 22473 - Graphics: Nothing under graphics/ should set the errno. From 22474 Gregory Nutt. 22475 - Graphics: Fix a coordinate system error in nx_filltrapezoid(). 22476 When no clipping rectangle is falls, it falls back to use the 22477 entire window as for the clip. However, that window must then then 22478 be in window relative coordinates, not in absoute device 22479 coordinates. From Gregory Nutt. 22480 22481 * Common Board Logic: 22482 22483 - boardctl(): Fix compiling error when set 22484 CONFIG_BOARDCTL_IOCTL/CONFIG_BOARDCTL_UNIQUEID. From Kevin Liu. 22485 22486 * Common Drivers: 22487 22488 - INA3221: Fix errors in INA3221 register field addresses and 22489 bitfield values. Signed value was losing its signed-ness due to 22490 use of unsigned type for register. From Ken Pettit. 22491 - Serial Upper Half: Initialize OPOST and ONLCR in uart_register. 22492 From Xiang Xiao. 22493 - Serial Upper Half: Don't reset the circular buffer on close since 22494 DMA may still be transferring data in the background if the user 22495 closes the handle too quickly and the handle is opened with 22496 O_NONBLOCK. From Xiang Xiao. 22497 - 16550 UART: Fix error: 'g_uart0port' undeclared. From Xiang Xiao. 22498 - 16550 UART: Fix typo for UART1 flow field initialization From 22499 Gregory Nutt. 22500 - CDC/ACM HCD: Fixes to the IOCTL method in recovery of UART pointer 22501 and in names of Termios-related field. From xhbm. 22502 - USB Device: Fix type for USBDEV_TRACE_INITIALIDSET in Kconfig. 22503 From Mateusz Szafoni. 22504 - TCA64xx: Fix some errors in the TCA64XX driver. From Bruno 22505 Schwander. 22506 - SYSLOG RAMLog: Fix error: Conflicting types for 'ramlog_addchar' 22507 From Xiang Xiao. 22508 - NRF24L01: Fix uninitialized irq_work which was causing a 22509 hard_fault on interrupt handler whenever something was sent from 22510 nrf24l01_term From Petri Ahonen. 22511 - MCP2515: Use kmm_zalloc to allocate device state structure. Fix 22512 some compiler errors. From Valmantas Paliksa. 22513 22514 * Architecture Common: 22515 22516 - arch/ Common: Remove architecture-specific watchdog.h and 22517 arm-elf.h because they are empty. The arm-elf header file was 22518 never used; the empty watchdog.h header file was used in only one 22519 place. From Xiang Xiao. 22520 - arch/ Common: Move up_pminitialize() after timer_initialize() 22521 From ligd. 22522 - arch/ Common: Align semi-hosting call style with other syscalls in 22523 architecture-specific syscall.h. From Xiang Xiao. 22524 - arch/ Common: Every file that uses serial IOCTLs (TIOC*) must 22525 explicity include nuttx/fs/ioctl.h. This was included previously 22526 via sneak path in the now deleted arch/serial.h. From Gregory Nutt. 22527 - arch/ Interfaces: Rename sched_process_cpuload to 22528 nxsched_process_cpuload. All internal sched_ functions should be 22529 prefixed with nx. From Valmantas Paliksa. 22530 22531 * ARMv7-A: 22532 22533 - ARMv7-A MMU: Updating the cp15_wrttb and cp15_wrdacr functions to 22534 use inline assembly in the correct way. The incorrect method was 22535 generating errors as ARMv7-a expects the MCR/MRC instructions to 22536 provide registers as an argument(MRC p15, 0, <Rt>, c2, c0, 0) and 22537 the code was providing a constant value(and hence the build 22538 error). From Bilal Wasim. 22539 - ARMv7-A: Remove inclusion pg_macros.h for armv7-a since this 22540 header file does not exist. From zhangyuan7. 22541 - ARMv7-A: Guard some assembly files if configuration not selected. 22542 From zhangyuan7. 22543 - ARMv7-A GIC: Fix assemble error when including gic.h From Xiang 22544 Xiao. 22545 - ARMv7-A GIC: Don't use GIC_ICDDCR_ENABLEGRP1 for GIC NONSECURE 22546 since this bit doesn't exist in this mode. From liuzhuang. 22547 22548 * ARMv7-R: 22549 22550 - ARMv7-R Syscall: In arch/arm/include/syscall.h, add missing 22551 inclusion of arch/armv7-r/syscall.h for Cortex-R. From Xiang Xiao. 22552 22553 * ARMv7-M: 22554 22555 - ARMv7-M Initialization: As noted by Roland Takacs in Bitbucket 22556 issue 141, there is a compilation error for STM32 if CONFIG_NET and 22557 CONFIG_NETDEV_LATEINIT are selected. That was due in part to the 22558 commit which extended up_netinitialize() with a 22559 !defined(CONFIG_NETDEV_LATEINIT) guard but did not add the guard to 22560 concrete implementations. I say "in part" because I don't think 22561 that the original intent of commit 19e16cb was to enable an 22562 alternative initialization of MCU internal Ethernet support but 22563 rather to enable support of external Ethernet devices that may have 22564 dependencies on, for example, SPI. However, this is still a proper 22565 fix to avoid the compilation error that can occur with this 22566 combination of configuration options. From Gregory Nutt. 22567 - ARMv7-M Configuration: ARCH_HIPRI_INTERRUPT shouldn't select 22568 ARMV7M_USEBASEPRI. First because that is a violation of the 22569 layered nature of the Kconfig architecture, but also because then 22570 Kconfig will generate errors when high priority interrupts are used 22571 with other architectures. From Xiang Xiao. 22572 - ARMv7-M Vector Table: Make the default NVIC_VECTAB_TBLOFF_MASK 22573 safer. The base address of the new vector table must be aligned to 22574 the size of the vector table extended to the next larger power of 22575 2. From Xiang Xiao. 22576 - ARMv7-M RAM Vectors: Correct bad NVIC_VECTAB_TBLOFF_MASK 22577 definitions in previous commit. Were missing bits in the mask. 22578 Raised DEBUGASSERT in armv7-m/up_ramvec_initialize.c line: 144. 22579 From Mateusz Szafoni. 22580 22581 * Expressif ESP32 Drivers: 22582 22583 - ESP32 Timer ISR: Fix backward comparison. From Gregory Nutt. 22584 - ESP32 Serial: Fix some backward arguments. Correct 2-stop bit 22585 setting. From Gregory Nutt. 22586 22587 * Microchip/Atmel SAMD2x/L2x Drivers: 22588 22589 - SAMD2/L2 Serial: SAMD2/L2 serial driver. It needs 22590 sam_usart_enable(). to work From Alan Carvalho de Assis. 22591 22592 * Microchip/Atmel SAMD3/4 Drivers: 22593 22594 - SAM3/4 Ethernet: Port Anthony Merlino's SAMv7 fix to similar 22595 Ethernet driver for the SAM3/4. From Gregory Nutt. 22596 22597 * Microchip/Atmel SAMV7 Drivers: 22598 22599 - SAMv7 SPI: Fix DMA Tx/Rx timeout issue. From Kevin Liu. 22600 - SAMv7 QSPI: Compile error when set CONFIG_SAMV7_QSPI_DLYBCT. 22601 From Kevin Liu. 22602 - SAMv7 Ethernet: The logic for determining the number of queues for 22603 SAMV71 must be extended. All SAMv7 parts increase the number of 22604 queues from 3 to 6 at revision B, not just the SAMV71. From 22605 Gregory Nutt. 22606 - SAMv7 Ethernet: Fixes rxdesc index logic to handle Buffer Not 22607 Available (BNA) condition. If a SOF is found, but no EOF, don't 22608 move past the frame. Instead, keep the index at the SOF buffer 22609 until the rest of the data is written. This fixes a receiver 22610 lockup condition where the peripheral and this driver get out of 22611 sync with there head pointers. In this case the driver has moved 22612 past buffers it owns, without clearing ownership, which results in 22613 the peripheral and driver in a deadlock with each other. From 22614 Anthony Merlino. 22615 22616 * Microchip/Atmel SAMA5Dx Drivers: 22617 22618 - SAMA5Dx Ethernet: Port Anthony Merlino's SAMv7 fix to similar 22619 Ethernet driver for the SAMA5Dx. From Gregory Nutt. 22620 22621 * Microchip/Atmel SAMA5Dx Board: 22622 22623 - SAMA5D2-XULT: Move console from FLEXCOM4 to UART1. FLEXCOM4 does 22624 not work for the Arduino serial. UART1 is used with the VCOM 22625 provided by the EDBG. From Gregory Nutt. 22626 22627 * NXP i.MXRT: 22628 22629 - i.MXRT Clock Configuration: If SDRAM is actived it was only 22630 running at 40MHz. This was becaus imxrt_clockconfig.c changed the 22631 SEMC clock divider after the DCD was configured. This commit 22632 corrects that. From Johannes. 22633 22634 * NXP i.MXRT Drivers: 22635 22636 - i.MXRT GPT: Correct register offsets. From David Sidrane. 22637 - i.MXRT TMR: Fix addressing and restructure using common offset. 22638 From David Sidrane. 22639 - i.MXRT ADC: Error in offset. From David Sidrane. 22640 22641 * NXP/Freescacle Kinetis Boards: 22642 22643 - Teensy-3.x: Fix a mismatch in types in defconfig. From Gregory 22644 Nutt. 22645 22646 * NXP LPC17xx: 22647 22648 - LPC176x Clock Configuration: The code preserves undocumented 22649 reserved bits only if board does not set them to keep previous 22650 behavior for boards where developers (hopefully) know what values 22651 should be set into these bits. From Pavel Pisa. 22652 - LPC17xx Clock Configuration: The enable of EMC clocks has to be 22653 preserved when already enabled by loader. EMC and related pins 22654 configuration has to be skipped if the system is run from SDRAM. A 22655 region of SDRAM which is used by system must not be used for heap. 22656 From Pavel Pisa. 22657 22658 * NXP LPC17xx Drivers: 22659 22660 - LPC17xx CAN: The name can_txready clashes with Nuttx CAN core 22661 global function. LPC178x has only single LPC17_SYSCON_PCLKSEL with 22662 only single divisor. From Pavel Pisa. 22663 22664 * NXP LPC17xx Boards: 22665 22666 - Open1788: Add missing MPU configuration option. From Gregory Nutt. 22667 22668 * On Semi LC823450 Boards: 22669 22670 - LC823450-XGEVK: Remove -nostdinc to avoid build error From 22671 Masayuki Ishikawa. 22672 22673 * STMicro STM32: 22674 22675 - STM32: Don't try including stm32_gpio.h from within chip/*.h 22676 header files. Not only is bad style for a layered inclusion 22677 system, but it doesn't always work. From Gregory Nutt. 22678 22679 * STMicro STM32 Drivers: 22680 22681 - STM32 PWM: Fix polarity and IDLE state configuration From Mateusz 22682 Szafoni. 22683 - STM32 ADC, PWM and TIM: (1) missing T1TRGO2 for JEXTSEL, (2) fix 22684 sample time configuration for channels. The array index for 22685 channels was missing, (3) fix TRGO/TRGO2 configuration, and (6) 22686 support for advanced timers channel 5 and 6. From Mateusz Szafoni. 22687 - STM32 Heap: Change 'if CONFIG_STM32_HAVE_CCM' to 'ifdef 22688 CONFIG_STM32_HAVE_CCM' to avoid a warning when 22689 CONFIG_STM32_HAVE_CCM is not defined. From Gregory Nutt. 22690 - STM32 Oneshot Timer: Fix an error introduced be a previous timer 22691 commit. From Maximilian Kriegleder 22692 - STM32 Tickless Mode and Free-Running Timer: Apply Max's 22693 stm32_oneshot.c fix to the tickless implementation and to the 22694 freerunning time. From Mateusz Szafoni. 22695 - STM32 PWM: Set CCPxP and CCPxNP bits if polarity is negative. 22696 Missing commas in initializers could break compilation in certain 22697 configurations. From Mateusz Szafoni. 22698 - STM32F7 Interrupts: Add the missing macro STM32_IRQ_NIRQS used by 22699 arch/arm/src/stm32f7/stm32_irq.c. From Kejun ZHOU. 22700 - STM32H7 DMA: Fix AHB1 base adresses memory map. From Mateusz 22701 Szafoni. 22702 - STM32H7 SysTick: H7 appears to ignore the SysTick CLKSOURCE bit 22703 and use the CPU clock in all cases. From Mateusz Szafoni. 22704 22705 * STMicro STM32 Boards: 22706 22707 - B-L072Z-LRWAN1: Fix typo in SPI1 pin definitions. From Mateusz 22708 Szafoni. 22709 - STM32F429I-DISCO: Handle multiple calls to the LCD 22710 up_fbinitialize() function. From Gregory Nutt. 22711 - STM32F769I-DISCO: Florian R. H�lzlwimmer reports that 22712 stm32_appinitialize.c often has missing OK and NULL definitions. 22713 This should be fixed by including sys/types.h where they are 22714 defined. From GregoryN. 22715 - STM32F769I-DISCO: Remove CONFIG_STM32F7_QUADSPI=y from the 22716 configuration. This was apparently set before the implementation 22717 was added. Now that the implementation was added, the configuration 22718 will not build because it requires that QSPI GPIO pin definitions 22719 be provided in the board.h header file. From Gregory Nutt. 22720 22721 * TI AM335x Drivers: 22722 22723 - AM335x Serial: Eliminate an error 'TIOCSBRK undeclared. From 22724 Gregory Nutt. 22725 22726 * C Library/Header Files: 22727 22728 - strto*: In alll strto* function family, did't consume single '-' 22729 or '+', allow sign in strotul(l)). From Johannes. 22730 - getopt(): Add logic to reinitialize the stale context for the 22731 FLAT/PROTECTED builds. In these builds getopt() global variables 22732 may be shared by many tasks. If any task exits the getopt() loop 22733 before all command line arguments have been parsed, then getopt() 22734 global variables will be left in a bad state. The next time 22735 getopt() is called, this logic should detect the bad state and 22736 force the state of getopt() to be re-initialized so that it can be 22737 reused. This logic is not full proof (it would fail, for example, 22738 if you tried to parse the same command line twice) but should catch 22739 the typical misuse cases. From Xiang Xiao. 22740 - sscanf(): Initialized the lastc pointer to avoid the checks for 22741 NULL. Removed a bug in the floating point parsing which allowed 22742 several signs after each other. From Johannes. 22743 - lib_vsprintf() (Legacy): No precision specifier resulted in 22744 precision 0 but should be precision 6. From Johannes. 22745 - lib_vsprintf() (Legacy): Correct justification for alternate forms 22746 of %p and %P From ligd. 22747 - lib_vsprintf() (Nano): Add long long support. 22748 CONFIG_LIBC_LONG_LONG needs at least CONFIG_NANO_PRINTLEVEL 2. 22749 Code size for compile without CONFIG_LIBC_LONG_LONG shouldn't be 22750 affected. From Johannes. 22751 - lib_vsprintf() (Nano): Remove CONFIG_LIBC_PRINT_MINIMAL. The 22752 output in that configuration is unsatisfactory and inappropriate 22753 for use with NuttX. For example, the output from many NSH commands 22754 become corrupted and useless. Doesn't belong in this context. 22755 From Gregory Nutt. 22756 - libs/libc/symtab: Remove unused symtab_findorderedbyvalue(). From 22757 Xiang Xiao. 22758 - libs/libc/machine/arm: Fix the minor issue in libc arm machine 22759 folder; MOVW/MOVT should use zero(not sign) extension. From Xiang 22760 Xiao. 22761 - libs/libc/libc.csv: Should be locale.h not local.h. From Joao 22762 Matos. 22763 - libs/libc/libc.csv: Needed logic for correct compilation if not 22764 using CONFIG_LIBC_WCHAR. From Joao Matos. 22765 - libxx: Always include libxx_cxa_guard.cxx in the build for for 22766 uclibcxx. From zhangyuan7. 22767 22768 - include/stdbool.h: Define bool only when __cplusplus isn't 22769 defined. From Xiang Xiao. 22770 - include/nuttx/list.h: Added a Linux-compatible list 22771 implementation. From zhuyanlin. 22772 - include/nuttx/irq.h: Fix enter_critical_section/spin_lock_irqsave 22773 macro typo error and remove the duplicated inclusion of 22774 arch/irq.h. From Xiang Xiao. 22775 - include/dlfcn.h: Correct naming of standard header file. Should 22776 be dlfcn.h, not dllfcn.h. From Gregory Nutt. 22777 - include/nuttx/nx/nxmu.h: This header file could be lethal; it 22778 declared an #error if CONFIG_DISABLE_MQUEUE=y. From Gregory Nutt. 22779 - include/nuttx/compiler.h: Important fix for C++ users. 22780 compiler.h was using the value of __STDC_VERSION__ to determine if 22781 inline functions are supported or not. If not then the keyword 22782 inline was defined out. Good for C but bad for C++ because C++ 22783 does not define __STDC_VERSION__ at all. C++ applications may 22784 draw in compiler.h indirectly via other head files and this can 22785 result in C++ compiler problems since 'inline' is defined out. 22786 This fix is to ignore the (undefined) __STDC_VERSION__ if 22787 __cplusplus is defined. From Gregory Nutt. 22788 - include/nuttx/elf.h: Adds missing extern "C" __cplusplus guard. 22789 From Anthony Merlino. 22790 - include/poll.h: Remove un-named union from 'struct pollfd'. It 22791 is not required by OpenGroup.org and violates the NuttX C coding 22792 standard because it is not C89 compatible. From Gregory Nutt. 22793 - libs/libc/Makefile, libs/libnx/Makefile, and mm/Makefile: Remove 22794 obj-path MKDEPS option since make dependency target (MT) is not 22795 supported by some toolchains. From anchao. 22796 - include/nuttx/compiler.h: Assume inline support if 22797 __STDC_VERSION__ not defined. From Xiang Xiao. 22798 22799 * Tools: 22800 22801 - tools/convert-comments.c: Fix an error in handling of a blank C++ 22802 comment before a comment block. From Gregory Nutt. 22803 - tools/lowhex.c: Fix an initialization problem that was causing 22804 some odd behavior at the beginning of lines. From Gregory Nutt. 22805 - tools/nxstyle.c: Fix logic that detects if an operator is 22806 correctly delimited with spaces. sched/: Various changes because 22807 sched/ C files were used as Guinea Pigs to test nstyle.c. From 22808 Gregory Nutt. 22809 - tools/nxstyle.c: Was confusing hex constants with strings staring 22810 with 'x'. Added logic to complain about hex constants containing 22811 upper case characters. From Gregory Nutt. 22812 - tools/nxstyle.c: Fix logic error that prevent detecion of '/' and 22813 '/=' as operators. net/: Minor updates resulting from testing 22814 tools/nxstyle. From Gregory Nutt. 22815 22816 * NSH Library: apps/nshlib: 22817 22818 - NSH Console: Fix copy paste errors. Some Kconfig configuration 22819 names needed CONFIG_ prefix. From David Sidrane. 22820 - nshlib/nsh_timcmds.c: Uninitialized struct tm caused 'date -s' to 22821 fail. From Valmantas Palik�a. 22822 22823 * Examples: apps/examples: 22824 22825 - apps/examples/nxterm: Replace direct calls to nxtk_register() 22826 with legal, indirect calls via boardctrl(BOARDIOC_NXTERM). 22827 Replace calls to (deleted) nxterm_unregister(). The correct way 22828 to delete a driver is by unlink'ing it. From Gregory Nutt. 22829 - apps/examples/nxterm: Most configuration options were not 22830 available in the Kconfig file. From Gregory Nutt. 22831 - apps/examples/nxterm: Replace illegal direct calls to 22832 nxterm_redraw() and nxterm_kbdin() with new boardctl() calls. 22833 From Gregory Nutt. 22834 - apps/examples/nxterm: NxWM passed the size of the NxTK sub-window 22835 but nxterm example passed the size of the complete NxTK window. 22836 They must be made consistent. From Gregory Nutt. 22837 22838 * Graphics Utilities: apps/graphics: 22839 22840 - apps/graphics/NxWidgets/nxwm: Correct an error in the type of the 22841 return value in CCalibration. From Gregory Nutt. 22842 - apps/graphics/NxWidgets/nxwm: Replace direct calls to 22843 nxtk_register() with legal, indirect calls via 22844 boardctrl(BOARDIOC_NXTERM). Replace calls to (deleted) 22845 nxterm_unregister(). The correct way to delete a driver is by 22846 unlink'ing it. From Gregory Nutt. 22847 - apps/graphics/NxWidgets: Replace illegal direct calls to 22848 nxterm_redraw() and nxterm_kbdin() with new boardctl() calls. 22849 From Gregory Nutt. 22850 22851 * Modbus: apps/modbus: 22852 22853 - apps/modbus/Kconfig: Fix modbus master Kconfig. Modbus Master 22854 ASCII compiles correctly. From Alan Carvalho de Assis. 22855 22856 * Network Utilities: apps/netutils: 22857 22858 - apps/netutils/dhcpc/dhcpc.c: Fix an error for DHCP REQUEST 22859 receiving a NAK.In DHCP Request operation, no need to update 22860 ciaddr to the client address and keep it as 0. From Kevin Liu. 22861 22862 * System Utilities: apps/system: 22863 22864 - apps/system/vi/vi.c: Fix an infinite loop bug that can show up in 22865 some cases (plus a couple of other items). From Ken Pettit. 22866 - apps/system/vi: Condition KEY_CMDMODE_REPEAT with 22867 CONFIG_SYSTEM_VI_INCLUDE_COMMAND_REPEAT to avoid build error when 22868 option is not selected. From Anthony Merlino. 22869 - apps/system/nxplayer/nxplayer.c: Fix build error when only enable 22870 CONFIG_AUDIO_EXCLUDE_VOLUME is enabled. From ZhongAn. 22871 - apps/system/system/system.c: Correct a path name. From anchao. 22872 - apps/system/taskset: Fix command arguments are not passed. From 22873 Masayuki Ishikawa. 22874 22875 * Testing: apps/testing: 22876 22877 - apps/testing/ostest/timedmutex.c: pthread_mutex_timedlock() 22878 returns EDTIMEDOUT on a timedout, not EAGAIN. From Gregory Nutt. 22879 22880 * Tools: apps/tools: 22881 22882 - apps/tools/mksymtab.sh: 'export LC_ALL=C' to get the traditional 22883 sort order From anchao. 22884 22885NuttX-7.30 Release Notes 22886------------------------ 22887 22888The 130th release of NuttX, Version 7.30, was made on May 19, 2019, 22889and is available for download from the Bitbucket.org website. Note 22890that release consists of two tarballs: nuttx-7.30.tar.gz and 22891apps-7.30.tar.gz. These are available from: 22892 22893 https://bitbucket.org/nuttx/nuttx/downloads 22894 https://bitbucket.org/nuttx/apps/downloads 22895 22896Both may be needed (see the top-level nuttx/README.txt file for build 22897information). 22898 22899Additional new features and extended functionality: 22900 22901 * Core OS: 22902 22903 - pthreads: Added non-standard pthread_get_stackaddr_np() and 22904 pthread_get_stacksize_np(). From Joao Matos. 22905 - boardctl(): Add a command to start the VNC server. From Gregory 22906 Nutt. 22907 - Signals: Remove references to CONFIG_DISABLE_SIGNALS in many 22908 files. Signals can no longer be disabled. From Gregory Nutt. 22909 22910 * Wireless/Wireless Drivers: 22911 22912 - NRF24L01: Add support for "multicast" TX mode - no waiting for ACK 22913 (needs to be enabled with fcntl SETTXPAYLOADNOACK) From Leif Jakob. 22914 22915 * Graphics/Display Drivers: 22916 22917 - NX Graphics: Add new server->client callback to notify the window 22918 client of server events. Remove the old 'blocked' callback and just 22919 make it one case of an 'event' callback. From Gregory Nutt. 22920 - NX Graphics: Implement new interfaces nx_synch() and nxtk_synch(). 22921 This are used to synchronize the NX server with the window client. 22922 Currently most of the logic is equivalent to nx_block() and 22923 nxtk_block(), but with slightly different semantics. They are 22924 separate now because they are likely to diverge in the future. 22925 From Gregory Nutt. 22926 - NX Graphics: Add support for modal windows. From Gregory Nutt. 22927 - NX Graphics: Implement a software cursor. The cursor behaves 22928 like a "sprite", always at the top of the display with a 22929 transparent background. Includes new NX interfaces to show/hide 22930 the cursor, set the cursor image, and to move the cursor position. 22931 From Gregory Nutt. 22932 - NX Graphics: Added support for hiding windows. This features is 22933 needed by Twm4Nx: When a window is iconified, the icon should 22934 appear on the background and the window should disappear (i.e., be 22935 hidden). The windows needs to remain healthy and to be updated in 22936 all ways, but it cannot affect the display content. Conversely, 22937 when the icon is clicked, the icon needs to be hidden on the 22938 background and the window needs to be restored in its current 22939 state (which may be different than the state of the window at the 22940 time it was iconified. From Gregory Nutt. 22941 - NX Graphics: Windows can now be created in the hidden state. 22942 This can be used to clean up initial window presentation which may 22943 involve several steps. This makes those steps all invisible until 22944 nx[tk]_setvisibility() is called to make the windows visible. 22945 From Gregory Nutt. 22946 - NX Graphics: Add new NX interfaces to query if a window is hidden 22947 or not. From Gregory Nutt. 22948 - NxTerm IOCTLs: Replace specific interfaces between boardctl and 22949 nxterm with a generalized IOCTL interface. From Gregory Nutt. 22950 - NxTerm: Add a new IOCTL that can be used to inform NxTerm that 22951 the size of a window has changed. From Gregory Nutt. 22952 22953 * Other Common Device Drivers: 22954 22955 - CAN Upper Half: Support multiple readers of the same port From 22956 Valmantas Paliksa. 22957 - MAX7456: Adds a read-only (for now) /dev/osd0/CM interface for 22958 obtaining the chip's onboard NVM character map data. Use seek() 22959 to position the cursor over a desired subset of bytes, or request 22960 a large read to obtain the entire EEPROM memory contents. Values 22961 are returned in binary form. Use hexdump, etc. to format them for 22962 viewing. From Bill Gatliff. 22963 - Serial Upper Half: The upper half serial driver configuration 22964 CONFIG_SERIAL_DMA used to enable DMA on both RX and TX streams. 22965 This was replaced with CONFIG_SERIAL_RXDMA and CONFIG_SERIAKL_TXDMA 22966 which will permit supporting DMA on only one or both streams. 22967 From Gregory Nutt. 22968 - FUSB303: Add FUSB303 driver From Juha Niskanen. 22969 22970 * Microchip PIC32MZ Drivers: 22971 22972 - PIC32MZ GPIO: Adds support for edge detect mode. Slew Rate was 22973 also added for completeness. From Abdelatif Guettouche. 22974 22975 * Microchip/Atmel SAMv7 Boards 22976 22977 - SAME70-xplained: Add a configuration for test Twm4Nx using VNC. 22978 From Gregory Nutt. 22979 22980 * Microchip LPCxx Drivers: 22981 22982 - LPC17xx Ethernet: Added support for KSZ8081RNA PHY to LPC17xx 22983 Ethernet driver. From jjlange. 22984 - LPC17xx Ethernet: Added support for Ethernet PHY ioctl() on 22985 LPC17xx. From jjlange. 22986 22987 * NXP i.MX RT: 22988 22989 - .i.MXRT1020: Gets imx1020 family support started. It is pretty 22990 similar, but subtly different, to 1050/60 (less PLLs, less GPIO 22991 banks, differently numbered ports etc. etc.). 22992 22993 Moved each of the imxrt family-specific files into its own 22994 subdirectory to tidy things up a bit, and remove the vast majority 22995 of ifdefs from the mainline code. 22996 22997 From Dave Marples. 22998 22999 * NXP LPC54xx Drivers 23000 23001 - LPC54xx USB FS Host: Bring in the USB FS OHCI driver from LPC17. 23002 This is a quick'n'dirty port from LPC17 that I hope finish 23003 sometime later. Currently, it is missing hardware clocking setup 23004 and is not even hooked into the build system yet. From Gregory 23005 Nutt. 23006 23007 * NXP LPC54xx Boards 23008 23009 - LPCXpresso-LPC54628: Add a Twm4Nx configuration. From Gregory Nutt. 23010 23011 * Sony CXD56xx 23012 23013 - CXD56xx: Add initial CXD56xx chip driver sources. From Nobuto 23014 Kobayashi. 23015 23016 * Sony CXD56xx Spresense Board 23017 23018 - Spresense: Add Spresense board support. This is not the full 23019 Spresense BSP from Sony, only the barebones logic to present an 23020 NSH console. From Nobuto Kobayashi. 23021 23022 * STMicro STM32: 23023 23024 - STM32F7 Clocking: Add support for using the HSE in bypass mode, 23025 configured by board.h From Anthony Merlino. 23026 - STM32F7 Clocking: Added support for TICKLESS mode. From Valmantas 23027 Paliksa. 23028 - STM32H7 Backup Domain: Add backup domain control registers. From 23029 Jukka Laitinen. 23030 - STM32H7 Clocking: Set the STM32H7 default HSI pre-divider to 4. 23031 The I2C driver currently assumes HSI clock to be 16MHz. From Jukka 23032 Laitinen. 23033 - STM32H7 Memorymap.: Add the STM32H7 SYSTEM_UID and DEBUGMCU_BASE 23034 register definitions. From Jukka Laitinen. 23035 - STM32L071x: Add support for STM32L071x. From Mateusz Szafoni. 23036 23037 * STMicro STM32 Drivers: 23038 23039 - STM32 OTGHS Host: Allow VBUS monitoring for the OTG_HS host 23040 driver. From Jason Harris. 23041 - STM32F0/L0 ADC: Initial ADC support for the STM32 M0 From Mateusz 23042 Szafoni. 23043 - STM32F0/LO I2C: Port STM32F7 I2C to STM32F0/L0, From Mateusz Szafoni. 23044 - STM32F1 FLASH: As noted by Matias N, the FLASH base address used 23045 was incorrect. It was using the address of the FLASH data, not 23046 the address of the FLASH registers. From Gregory Nutt. 23047 - STM32F3 I2C: Port STM32F7 I2C to STM32F3. From Mateusz Szafoni. 23048 - STM32F7 Ethernet.c: Auto-generate Ethernet MAC address from 23049 device unique ID. From Valmantas Paliksa. 23050 - STM32F7 FLASH: Add flash block mapping support for progmem. From 23051 Valmantas Paliksa. 23052 - STM32F7 FMC: Updated stm32_fmc.h with more FMC definitions. From 23053 Joao Matos. 23054 - STM32F7 GPIO: Adds additional pin alternate function for SPI2. 23055 From Anthony Merlino. 23056 - STM32F7 PWM: Ported the PWM from F4 to F7. From Eduard Niesner. 23057 - STM32F7 SDMMC: Support bypassing the input clock divider on the 23058 SDMMC interface. This enables using the full clock speed provided 23059 to the SDMMC interface with no dividing. From Anthony Merlino. 23060 - STM32F7 SPI: Add SPI DMA threshold configuration. From Valmantas 23061 Paliksa. 23062 - STM32F7 UID: Add UID access. From Valmantas Paliksa. 23063 - STM32F7 USB: USB High speed for STM32F7 series From Ramtin Amin. 23064 - STM32H7 Ethernet: Add stm32h7 Ethernet driver. This is the 23065 initial push for the Ethernet driver. The driver has been tested 23066 to be working on a nucleo board. This is still WIP, it doesn't 23067 for example do MAC filtering on HW level, but just receives all 23068 Ethernet packets. From Jukka Laitinen. 23069 - STM32H7 GPIO: Add the GPIO_ETH_RMII_RXD1 pinmap definition for 23070 STM32H7. From Jukka Laitinen. 23071 - STM32H7 SDMMC: Add STM32H7 SDMMC driver. It is mostly copied 23072 from STM32F7, with modified register addresses and bits, and IDMA 23073 dded. This is still WIP; it only works with IDMA. From Jukka 23074 Laitinen. 23075 - STM32H7 Timers: Add timer devices driver for STM32H7. This i 23076 mostly a forklift from stm32f7 with some h7 specific 23077 modifications. From Jukka Laitinen. 23078 - STM32L0 AES: Add support for AES for L0. From Mateusz Szafoni. 23079 - STM32L0 RND: Add support for RND. From Mateusz Szafoni. 23080 - STM32L0 HSI48: Add support for HS148 for L0. Move HSI48 enable 23081 from stm32_usbdev.c to stm32xx_rcc.c From Mateusz Szafoni. 23082 - STM32L4 USB FS Device: Add USB FS device support. From Juha 23083 Niskanen. 23084 - STM32L4 HSI48: Port HSI48 from STM32F0/L0 From Juha Niskanen. 23085 - STM32L4 CRS: Port CRS from STM32F0/L0 From Juha Niskanen. 23086 23087 * STMicro STM32 Boards: 23088 23089 - B-L072Z-LRWAN1: Add ADC example. From Mateusz Szafoni. 23090 - B-L072Z-LRWAN1: Add nxlines_oled example (ssd1306). Add support 23091 for the I2C tool From Mateusz Szafoni. 23092 - Nucleo-144: Added STM32_RCC_DCKCFGR2_DSISRC definition to board.h. 23093 From Joao Matos. 23094 - Nucleo-144: Mount sysfs for ifconfig for f767-netnsh/defconfig. 23095 Even if ifconfig is working to set IP, it will not work to display 23096 NICs (without args) From Phil Coval. 23097 - Nucleo-144: Add basic PWM support to nucleo-144 board. More PWMs 23098 and multi channels support may be investigated and added later. 23099 Tested on Nucleo-F767ZI. From Phil Coval. 23100 - Nucleo-F303ZE: Add nxlines_oled example (ssd1306) From Mateusz 23101 Szafoni. 23102 - Nucleo-H743ZI: Enable the FPU. From Jason Harris. 23103 - Nucleo-H743ZI: Add support for I2C devices: ssd1306, pca9635, 23104 i2ctools From Mateusz Szafoni. 23105 - Nucleo-H743ZI: Add default clock configuration for SDMMC for 23106 Nucleo-H743ZI's board.h. From Jukka Laitinen. 23107 - Nucleo-H743ZI: Add the input clock frequency definitions in 23108 board.h for all the drivers. Assumes internal clock source for 23109 all the timers. From Jukka Laitinen. 23110 - STM32F4 Discovery: Keep c++ global constructor symbols From 23111 Masayuki Ishikawa. 23112 - Nucleo-L073RZ: Add MFRC522 support From Mateusz Szafoni. 23113 - OmnibusF4: Add boardctl() reset logic. From Bill Gatliff. 23114 - OmnibusF4: Add board_ioctl() which is needed only if 23115 CONFIG_BOARDCTL_IOCTL=y is selected; Update NSH configuration 23116 to enable board IOCTLs and DFU mode reset. From Bill Gatliff. 23117 - STM32L Discovery: Add support for board_late_initialize(), Move 23118 common initialization logic out of board_app_initialize() into new 23119 file stm32_bringup.c From Gregory Nutt. 23120 - STM32F103-Minimum: Add PROCFS automount support From Alan 23121 Carvalho de Assis. 23122 23123 * Libraries/Header Files: 23124 23125 - include/alloca.h: Add alloca.h. Included limited implementation 23126 of alloc() that is only available for GCC versions 3 and above. 23127 From Joao Matos. 23128 - include/cxx/cstdlib: Add std::random() From Gregory Nutt. 23129 23130 * apps/ General: 23131 23132 - Many locations: Remove references to CONFIG_DISABLE_SIGNALS. 23133 Signals can no longer be disabled. From Gregory Nutt. 23134 23135 * Examples/Tests: apps/examples: 23136 23137 - apps/examples/fb: Add some awareness of overlays to 23138 apps/examples/fb From Matthew Koch. 23139 - apps/examples/lvgldemo. Update to Littlevgl 5.3. From Matthew 23140 Koch. 23141 - apps/examples/pwfb: Extend example to verify software cursors. 23142 From Gregory Nutt. 23143 - apps/examples/pwfb: Add options to reduce the number of windows. 23144 This is helpful during debug to reduce the complexity. From 23145 Gregory Nutt. 23146 23147 * Network Utilities: apps/netutils: 23148 23149 - apps/netutils/cjson: Support for the current version of cJSON. 23150 From Mateusz Szafoni. 23151 - apps/netutils/libcurl4nx: This is an initial commit libcurl4nx. 23152 It is not complete yet, but I still wish to commit the unfinished 23153 bits to describe the roadmap, and because it is already usable. It 23154 will be updated and fixed in the future weeks and months, certainly 23155 including POST support and later, SSL. From Sebastien Lorquet. 23156 - apps/netutils/netinit. This commit removes the private network 23157 initialization logic from NSH and puts in a common location at 23158 apps/netutils/netinit. Now that netork initialization logic can be 23159 used by applications that do not include NSH. From Gregory Nutt. 23160 - apps/netutils/netlib: Add a more flexible version of 23161 netlib_parsehttpurl(). This one can parse any URL, and is 23162 extensible so future improvements keep the same API. From Sebastien 23163 Lorquet. 23164 23165 * System Utilities: apps/system 23166 23167 - apps/system/spi: I needed a small test tool for spi in the style of 23168 the I2C tool, but I didn't see one so I've hacked one out of the I2C 23169 tool source. From Dave Marples. 23170 23171 * Graphics: apps/graphics: 23172 23173 - apps/graphics/twm4nx. This release introduces Twm4Nx. Twm4Nx is a 23174 "port" of TWM, Tab Window Manager (or Tom's Window Manager) version 23175 1.0.10 to NuttX NX windows server. No, a port is not the right 23176 word. It is are-design of TWM from the inside out to work with the 23177 NuttX NX server and NXWidgets. The name Twm4Nx reflects this 23178 legacy. But Twm4Nx is more a homage to TWM than a port of TWM. 23179 23180 The original TWM was based on X11 which provides a rich set of 23181 features. TWM provided titlebars, shaped windows, several forms of 23182 icon management, user-defined macro functions, click-to-type and 23183 pointer-driven keyboard focus, graphic contexts, and user-specified 23184 key and pointer button bindings, etc. 23185 23186 Twm4Nx, on the other hand is based on the NuttX NX server which 23187 provides comparatively minimal support. Additional drawing support 23188 comes from the NuttX NxWidgets library (which necessitated a 23189 conversion to C++). 23190 23191 Twm4Nx is greatly stripped down and targeted on small embedded systems 23192 with minimal resources. For example, no assumption is made about the 23193 availability of a file system; no .twmrc file is used. 23194 23195 The state of the "port" is available in 23196 apps/graphics/twm4mx/README.txt. To summarize: The port is fully 23197 functional but probably only at an alpha release level. The only 23198 missing critical feature is built-in touchscreen calibration. 23199 23200 - apps/graphics/littlevgl. Update to Littlevgl 5.3. From Matthew 23201 Koch. 23202 - apps/graphics/nxglyphs: Put all NxWidgets and NxWM glyphs into a 23203 common directory where they can eventually be shared. Decouple 23204 from nxwidgets and nxwm so that they can be used elsewhere. 23205 Creates include/graphics/nxglyphs.h From Gregory Nutt. 23206 - apps/graphics/nxglyphs: Add some new cursor bitmap images. From 23207 Gregory Nutt. 23208 - apps/graphics/nxglyphs: Add mkcursor.c. Will auto-generate 23209 cursor image header file from Gimp C output. From Gregory Nutt. 23210 - apps/graphics/nxglyphs: Add 16x16 cursor images. 30x30 are kind 23211 of large on small displays. From Gregory Nutt. 23212 - apps/graphics/nxglyphs: Add a new resize cursor image. From 23213 Gregory Nutt. 23214 - apps/graphics/nxwm: Separate NxWidgets and NxWM into separate 23215 directories. Remove old, common NxWidgets directory. From 23216 Gregory Nutt. 23217 - apps/graphics/nxwm: Move the NxWM unit test main() to apps/nxwm. 23218 It is no longer a unit test, but the main startup entry point for 23219 NxWM. From Gregory Nutt. 23220 - apps/graphics/nxwidgets: Update NX window clients so that they 23221 use the new 'event' callback (vs. the obsoleted 'blocked' callback). 23222 From Gregory Nutt. 23223 - apps/graphics/nxwidgets: Add a synchronize method to every window. 23224 This is a wrapper arounc nx[tk]_sync and permits C++ applications 23225 to synchronize with the NX server. From Gregory Nutt. 23226 - apps/graphics/nxwidgets: Add support for modal windows. From 23227 Gregory Nutt. 23228 - apps/graphics/nxwidgets: Add cursor control methods to the 23229 CNxServer class. From Gregory Nutt. 23230 - apps/graphics/nxwidgets: Add a method to CButtonArray that will 23231 allow us to dynamically resize the array (at the cost of losing all 23232 button labels). From Gregory Nutt. 23233 - apps/graphics/nxwidgets: Fix a possible deadlock condition when 23234 waiting for window geometry data that will never come. Fixed by 23235 re-requesting geometry data if we don't already have it. From 23236 Gregory Nutt. 23237 - apps/graphics/nxwidgets: Add handshake to 23238 CWidgetControl::getWindowHandle() to avoid returning a NULL 23239 handle. From Gregory Nutt. 23240 - apps/graphics/nxwidgets: CNxTkWindow, CNxWindow, CNxServer: Add 23241 support to create RAM backed windows. From Gregory Nutt. 23242 - apps/graphics/nxwidgets: Add methods to all windows to query if a 23243 window is visible or hidden. From Gregory Nutt. 23244 23245Bugfixes. Only the most critical bugfixes are listed here (see the 23246ChangeLog for the complete list of bugfixes and for additional, more 23247detailed bugfix information): 23248 23249 * Core OS: 23250 23251 - Clock Initialization: A recent change broke Tickless mode for all 23252 architectures. The original change was intended to handle the 23253 case where up_timer_gettime may not start from zero case. The 23254 side effect is that this changed to order of initialization of 23255 clocking, breaking Tickless mode:: After this change the tickless 23256 timer structures are used before they are initialized in 23257 clock_inittime(). The commit has been reverted. 23258 - pthread Stack Attribute: Fixed pthread_attr_get/setstacksize 23259 param type to size_t. From Joao Matos. 23260 - Signals: The abnormal termination signal handler was just calling 23261 exit() conditionally when, for example, Ctrl-C is sent to a task. 23262 The abnormal termination handler must obey the rules of cancellation 23263 points: If cancelation is disabled, then the abnormal termination 23264 logic must wait for cancelation to be re-enabled; If cancellation 23265 is deferred then the abnormal termination logic may have to wait 23266 for the victim task to enter or exit a cancellation point. From 23267 Gregory Nutt. 23268 - Syscall: Added support for munmap() syscall. From Joao Matos. 23269 - Syscall: Fix a warning due to inconsistencies in return type in 23270 syscall.csv. From Gregory Nutt. 23271 - Syscall: Correct an error syscall.csv. Error occurred when 23272 creating the munmap() proxy if CONFIG_FS_RAMMAP is not defined. 23273 From Gregory Nutt. 23274 23275 * File System/Block and MTD Drivers: 23276 23277 - fs/littlefs/lfs.c: Fix lfs_format bug. In superblock disk root- 23278 block assignment, the second must be root[1]. From YanLin Zhu. 23279 23280 * Networking/Network Drivers: 23281 23282 - getsockname(): Fix addrlen check in socket debug features. 23283 Getsockname() checked erroneously a pointer agains 0, where the 23284 intention was to dereference the pointer and to check the length. 23285 This causes also a compilation failure if the code is compiled 23286 with CONFIG_DEBUG_FEATURES and with -Werror flag set. From Jukka 23287 Laitinen. 23288 - Network Locking: net_lock() and net_restorelock() now return a 23289 value. That values is the standard zero on success; negated errn 23290 value on failure. This return value is only needed for 23291 -ECANCELED. That cancellation indication needs to ripple all the 23292 way back to the highest levels where the cancellation can be acted 23293 on. This commit only adds the return value; it does not add 23294 checking for the return values of net_lock() and net_restorelock() 23295 at higher levels. That is required too. From Gregory Nutt. 23296 - PHY Notification Driver: Change sprintf to strncpy in phy_notify. 23297 On some platforms, the sprintf doesn't accept a const char* as a 23298 format argument. From Jukka Laitinen. 23299 - 6LoWPAN HC06: Correct an endian-ness problem in HC06 decompression. 23300 From Ivan Ucherdzhiev. 23301 23302 * Wireless/Wireless Drivers: 23303 23304 - NRF24L01: Don't block in read if file descriptor is O_NONBLOCK. 23305 From Leif Jakob. 23306 23307 * Graphics/Display Drivers: 23308 23309 - NX Graphics: Fix an error in coordinate system usage. Expected 23310 rectangle in device coordinate frame, but was passing the 23311 rectangle in window-relative coordinate frame. From Gregory Nutt. 23312 - NX Graphics: Fix an oversight in the implementation of per-window 23313 framebuffers. It is true that redraw callbacks can be suppressed 23314 for all cases ... EXCEPT ONE: When the window is resized to a 23315 larger size, then the newly exposed territory must be drawn for 23316 the first time. From Gregory Nutt. 23317 - NxTK: Fix an error in handling mouse events for framed windows. 23318 When drawing, NX may report mouse positions outside of the Window. 23319 The is only for NX windows, but the outside-the-side positions were 23320 being discarded by nxtk_events(). From Gregory Nutt. 23321 - NxTK: Refuse to open a toolbar of height zero or less. From 23322 Gregory Nutt. 23323 - Nxglib: Correct bogus logic in nxgl_interesting(). From Gregory 23324 Nutt. 23325 - VNC Server: Fix an error in color conversion. From Gregory Nutt. 23326 23327 * Common Drivers: 23328 23329 - APDS9960: Initial state of allocated structure was not being set. 23330 Noted by Leif Jacob. From Gregory Nutt. 23331 - MFRC522: In mfrc522_read uid.sak must be different from 0x04 not 23332 as before from 0x00. SAK == 0x00 is a valid PICC type. Add 23333 interface to read MIFARE Ultralight data From Mateusz Szafoni. 23334 - Power: Fix build for battery gauge From Tom Kopriva. 23335 - Syslog: In syslog buffered mode, avoid IOB alloc lock-up with 23336 heavy network activity. This change alters the buffered syslog 23337 logic to use 'iob_tryalloc' instead of blocking 'iob_alloc' to 23338 avoid syslog printing from getting stuck when all IOBs are 23339 depleted by network activity. An issue was seen when large 23340 incoming TCP transfer uses free IOB buffers and processing 23341 threads try to use syslog which then block at iob_alloc. From 23342 Jussi Kivilinna. 23343 - USB CDC/ACM Device: This fixes a problem where the host sent a 23344 "get descriptor" message of type "standard" with a recipient of 23345 type "interface". Since the composite driver would only pass 23346 messages to the child interfaces when a message was not 23347 "standard", this message was not handled. I changed the condition 23348 so that the composite driver checks not only if this is a 23349 "standard" message but if it is also directed to the device. 23350 Otherwise, the handling is delegated to the children of the 23351 composite device. From Matias N. 23352 - USB HID: The usbhid_descriptor_s struct defined in hid.h included 23353 some optional fields that should not be hard-defined as part of 23354 that structure. An arbitrary number of optional entries could be 23355 included in the descriptor, but that is not properly represented. 23356 No code on NuttX currently depends on the structure definition 23357 with an optional descriptor so it is safe to remove. From Matias N. 23358 - USB MSC Device: Correct typo "const const" to "const". 23359 arch/arm/src/stm32/stm32_i2s.c: In debug assertions, it on a 23360 sample rate of 0, but based on other code comments this value 23361 implies disabling the i2s master clock. From Jason Harris. 23362 - Zerocross Driver: Fix some errors when debug assertions are 23363 enabled. From Matous Pokorny. 23364 - User Leds: Fix ledset validity check in ULEDIOC_SETALL ioctl. 23365 From Jussi Kivilinna. 23366 23367 * Architecture Common: 23368 23369 - All board interfaces (those starting with board_) must be defined 23370 in board-specific logic. Otherwise, they cannot be customized for 23371 specialized usage by different boards. The board_reset() 23372 interface was defined in architecture-specific logic that only 23373 called up_systemreset(). That is useless! This change removes 23374 the board_reset() implementation from the architecture-specific 23375 code and re-implements it in the src/ directory of each board that 23376 has CONFIG_BOARDCTL_RESET enabled. That is the correct functional 23377 partitioning. From Gregory Nutt. 23378 - Start-up: Remove dependency on CONFIG_ARCH_FPU for inclusion of 23379 nvic.h in all other *_start.c files. From Gregory Nutt. 23380 - Architecture initialization: up_initialize() needs to know about 23381 ramlog_consoleinit() From Jason Harris. 23382 23383 * Microchip PIC32MZ Drivers: 23384 23385 - PIC32MZ GPIO: Corrects the gpioirq when mismatch mode is 23386 selected.

From Beat K�ng. 23838 23839 * STMicro STM32 Boards: 23840 23841 - Olimex-STM32-E407: Added BMP180 initialization and a configuration 23842 to test the BMP180. From Juan Flores. 23843 - Olimex-STM32-E407: Add DAC support, add IN219 support, add timer 23844 driver support. From Juan Flores. 23845 - Olimex-STM32-E407: Add support for MRF24J40 radio. From Gregory 23846 Nutt. 23847 - Axoloti: Adds initial support for the Axoloti sound/music 23848 synthesizer board. Board is based on STM32F427 SoC. See 23849 http://www.axoloti.com/. From Jason Harris. 23850 - Nucleo-G071RB: Initial support for nucleo-g071rb. From Mateusz 23851 Szafoni. 23852 - Nucleo-L432KC: Add new configuration settings for CRS 23853 synchronization to board.h. From Juha Niskanen. 23854 - Nucleo-L432KC: Add support for testing the ina219 current sensor. 23855 From Sebastien Lorquet. 23856 - Nucleo-L452RE: Add new configuration settings for CRS 23857 synchronization to board.h.

Code is derives from STM32F4- 23861 Discovery. It can be enabled using CONFIG_BOARDCTL_RESET From Phil 23862 Coval. 23863 - Nucleo-L476RG: (1) Add I2C tool to board init, (2) Add support for 23864 AS726X spectral sensor From Fabian Justi. 23865 - Nucleo-L496ZG: Add new configuration settings for CRS 23866 synchronization to board.h. From Juha Niskanen. 23867 - STM32L476VG-Disco: Add new configuration settings for CRS 23868 synchronization to board.h. From Juha Niskanen. 23869 - STM32L4R9AI-Disco: Add ksh config, some updates for I2C, SPI and 23870 DFSDM support. From Juha Niskanen. 23871 - Nucleo-H743ZI: Add ADC support. From David Sidrane. 23872 - STM32F769I-Disco PWM: Enable PWM support for stm32f769i-disco 23873 board. 23874 - STM32L-Discovery: Add button support for stm32Ldiscovery. Add 23875 chronometer board config. From Alan Carvalho de Assis. 23876 23877 * TI AM335x: 23878 23879 - AM335x Clock Module: Add clock module registers definition. Switch 23880 to DMTIMER1 for systick. From Petro Karashchenko. 23881 23882 * TI AM335x Drivers: 23883 23884 - AM335x CAN, LCD: Add register description files for DCAN and LCD. 23885 From Petro Karashchenko. 23886 - AM355x I2C: Add register description files for I2C (plus various 23887 improvements to the WDOG register definitions) From Petro Karashchenko. 23888 - AM355x MCSPI: Add register description files for MCSPI. From Petro 23889 Karashchenko. 23890 - AM355x LCDC: This change brings in an initial LCD driver into the 23891 AM335x architecture. Ported from FreeBSD. From Gregory Nutt. 23892 - AM335x Framebuffers: Add logic to map the framebuffer to a non-cached, 23893 non-buffered memory region. From Gregory Nutt. 23894 - AM335x LCDC: Add logic to get/set the module reference clock. From 23895 Gregory Nutt. 23896 23897 * TI AM335x Boards: 23898 23899 - Beaglebone-Black LCD: Add a configuration for bringing up the LCDC 23900 driver. From Gregory Nutt. 23901 - Beaglebone-Black LCD: Framework (only) for TDA19988 and LCD support 23902 for Beaglebone Black. Can't use TDA19988 yet because there is no I2C 23903 driver. In the mean time, support LCD initialization using a fixed, 23904 configurable video mode. From Gregory Nutt. 23905 23906 * ZiLOG z16f ZNeo: 23907 23908 - z16f ZNeo: Add support for the latest 5.2.1 version of the ZDS-II 23909 toolchain. From Gregory Nutt. 23910 23911 * ZiLOG eZ80Acclaim!: 23912 23913 - Integrate support for the newest eZ80 ZDSII 5.3.0 toolchain. From 23914 Gregory Nutt. 23915 23916 * ZiLOG eZ80Acclaim! Drivers: 23917 23918 - eZ80 RTC: Integrate and verify the RTC driver From Gregory Nutt. 23919 - eZ80 RTC: Add an RTC lower half driver. From Gregory Nutt. 23920 23921 * ZiLOG eZ80Acclaim! Boards: 23922 23923 - MakerLisp: Add initial support for the MakerLisp eZ80 board. Ref: 23924 https://makerlisp.com/ From Gregory Nutt. 23925 - MakerLisp: Add hooks needed by SPI driver. Move SPI MMC/SD chip 23926 selected configuration from ez80_lowinit.c to here as is done in 23927 other NuttX architectures. This enables support for multiple 23928 devices on the SPI bus. From Gregory Nutt. 23929 - MakerLisp: Add Smart Flash Programmer project. From Gregory Nutt. 23930 - MakerLisp: Enable Procfs, RTC, SPI-based SD support, task name, NSH 23931 data command in NSH configuration.. From Gregory Nutt. 23932 - MakerLisp: Use .ztgt files from MakerLisp SDK. From Gregory Nutt. 23933 - MakerLisp: Add a tiny FLASH-resident loader that will load and 23934 start applications in Intel HEX format from an SD card. From 23935 Gregory Nutt. 23936 - MakerLisp: Bring in a new configuration to support execution 23937 entirely out of external SRAM. From Gregory Nutt. 23938 - MakerLisp: Add an sdboot configuration that will load .hex files 23939 from the SD card. From Gregory Nutt. 23940 - MakerLisp: Add a linker script to support copying the NuttX image 23941 from FLASH into external SRAM. From Gregory Nutt. 23942 - MakerLisp: The VGA display controller and keyboard controller come 23943 up by default emulating a terminal with 'newline mode' on. That is 23944 newlines expance to carriage-return, newline. This change turns that 23945 mode off. From Gregory Nutt. 23946 23947 * Libraries/Header Files: 23948 23949 - include/cxx/cstddef: Add C11++ std::nullptr_t From junmin-kim. 23950 - libc netdb: Implemented the netdb functions getnameinfo(), 23951 getservbyport(), and getservbyport_r(). From Michael Jung. 23952 23953 * Documentation 23954 23955 - Applied a style sheet to static HTML files. Put the TOC of each 23956 document to the side, where it made sense (in some documents the 23957 TOC was actually inside a section so it wasn't possible). In some 23958 cases the TOC is built with a table, in others with a <ul> element, 23959 so I had to accommodate for this. I also didn't go into collapsing, 23960 although this could really help for some long TOCs. From Matias N. 23961 - Coding Standard: Add a brief section summarizing the major 23962 differences between the NuttX C and C++ coding standards. This is a 23963 stop-gap measure in lieu of having a real C++ coding standard. From 23964 Gregory Nutt. 23965 - Coding Standard: Update requirements for indenting C pre-processor 23966 statements. From Gregory Nutt. 23967 - Coding Standard: Small change discouraging the practice of 23968 enclosing the value argument of 'return' statements in parentheses. 23969 From Gregory Nutt. 23970 - COPYING. Tools in the tools/ directory are not intended for binary 23971 redistribution and may not all conform to BSD licensing. From 23972 Gregory Nutt. 23973 23974 * Tools: 23975 23976 - tools/ocdconsole.py: OCD TCL interface changed after version 0.10 23977 of OpenOCD. This change allows the script to work with both the 23978 older and newer TCL interface. From Dave Marples. 23979 - tools/nxstyle.c: Tool depends on the file under test containing 23980 "Private Functions" or "Public Functions" block comments. Emit an 23981 error if neither are present in a C source. From Gregory Nutt. 23982 - tools/nxstyle.c: Bandaid-up logic that detects left brackets on the 23983 same line in global structure/enumeration types and initializers. 23984 From Gregory Nutt. 23985 - tools/nxstyle.c: No warning for declarations that begin in column 1 23986 within 'extern "C"'. This is because the 'extern "C"' is conditioned 23987 on __cplusplus so the declarations are not normally indented. From 23988 Gregory Nutt. 23989 - tools/: Add spk binary format. The .spk binary format is used on 23990 SPresence and other boards based on the CXD56 arch. To enable this 23991 binary format set in your config CONFIG_CXD56_BINARY=y. From Alin 23992 Jerpelea. 23993 - tools/: Add flash_writer for CXD56 boards. This flash writter is 23994 using the xmodem for firmware transfer for flashing please use: 23995 'tools/flash_writer.py -s -c /dev/ttyUSB0 -d -b 115200 -n nuttx.spk'. 23996 From Alin Jerpelea. 23997 23998 * apps/ General: 23999 24000 - Removed all references to CONFIG_DISABLE_POLL. The standard POSIX 24001 poll() can no longer be disabled. From Gregory Nutt. 24002 24003 * Examples/Tests: apps/examples: 24004 24005 - apps/examples/abntcodi: Adds test/demo program for ABNT CODI 24006 library. From Alan Carvalho de Assis. 24007 - apps/examples/webserver: Update to compile with 24008 CONFIG_NETUTILS_HTTPD_SENDFILE=y. Also some configs such as 24009 CONFIG_NETUTILS_HTTPDFILESTATS can be selected by menuconfig. 24010 From Masayuki Ishikawa. 24011 - apps/examples/chrono: Add chronometer apps example. From Alan 24012 Carvalho de Assis. 24013 24014 * Network Utilities: apps/netutils: 24015 24016 - apps/netutils/webserver: Add mp3 mime type to httpd.c. From 24017 Masayuki Ishikawa. 24018 - apps/netutils/webserver: Add directory listing to httpd. From 24019 Masayuki Ishikawa. 24020 - apps/netutils/webserver: Add web server info based on uname(). 24021 From Masayuki Ishikawa. 24022 24023 * Network Utilities: apps/wireless 24024 24025 - apps/wireless/gs2200m: Add usrsock daemon for Tilt GS2200M Wi-Fi 24026 module. From Masayuki Ishikawa. 24027 - apps/wireless/gs2200m: Add channel parameter for AP mode. From 24028 Masayuki Ishikawa. 24029 24030 * Graphics: apps/graphics: 24031 24032 - apps/graphics/nxglyphs: Add more modern looking button images for 24033 the Twm4Nx CONTEMPORARY theme. From Gregory Nutt. 24034 - apps/graphics/slcd: Adds a CSLcd class that will generate graphic 24035 simulated segments of an SLCD display. From Gregory Nutt. 24036 - apps/graphics/twm4nx: This change adds a calibration screen to 24037 Twm4Nx. In addition to the Calibration screen port from NxWM, this 24038 required extensions to the event handling logic to support (1) 24039 receiving raw, uncalibrated touchscreen inputs, (2) shutting down 24040 of externally controlled windows. From Gregory Nutt. 24041 - apps/graphics/twm4nx: Move application-related files into different 24042 directories to separate them from the core Twm4Nx files. From 24043 Gregory Nutt. 24044 - apps/graphics/twm4ndx: Compile out cursor support if we are using a 24045 mouse. From Gregory Nutt. 24046 - apps/graphics/twm4nx: Add an alternative COMPONTEMPORARY theme. 24047 Still has some artifacts on the display. From Gregory Nutt. 24048 - apps/graphics/twm4nx: Use custom CWidgetStyle to force Icon 24049 background to match selected desktop background. From Gregory Nutt. 24050 - apps/graphics/twm4nx: Add some definitions to support Themes. 24051 Background image is now optional. From Gregory Nutt. 24052 - apps/graphics/twm4nx: Add a configuration option to control the 24053 number of buttons in one column of the Icon Manager. The Icon 24054 anager no longer relies the default window width; now it 24055 determines a preferred window width based primarily on the font 24056 size. From Gregory Nutt. 24057 - apps/graphics/tmw4nx: Add a CClock class that implements the 24058 Twm4Nx digital clock based on the CSLcd simulated SLCD segements. 24059 From Gregory Nutt. 24060 - apps/graphics/twm4nx/README.txt: Add an overview of how to create 24061 Twm4Nx applications. From Gregory Nutt. 24062 24063 * Industry: apps/industry: 24064 24065 - apps/industry/abnt_codi: Adds support for ABNT CODI library. This 24066 is an energy meter protocol used in Brazil. From Alan Carvalho de 24067 Assis. 24068 24069Bugfixes. Only the most critical bugfixes are listed here (see the 24070ChangeLog for the complete list of bugfixes and for additional, more 24071detailed bugfix information): 24072 24073 * Core OS: 24074 24075 - Semaphores: Fix a bad assertion in priority inheritance logic. 24076 The comments state correctly that we cannot make any assumptions 24077 about the number of holders of the semaphore, yet the code 24078 asserts if there are any holders. This makes the code behave 24079 closer to what the comments say. From Gregory Nutt. 24080 - Memory Manager: Fix error that occurs when CONFIG_CPP_HAVE_VARARGS 24081 is not defined. In that case, the arguments to the debug macro will 24082 all be evaluated even though they are not used any variables that 24083 are references must at least be defined. From Gregory Nutt. 24084 - System Calls: Adapt the conditional compile logic on when to 24085 include the vfork() syscall proxy and stub to the logic used for 24086 vfork() itself. From Michael Jung. 24087 - System Calls: Fixed SYS_mount syscall define when CONFIG_FS_READABLE 24088 is undefined. From Joao Matos. 24089 - waitpid(): In waitpid, remember to grab the exited child ptr. After 24090 being unblocked in waitpid, the child pointer might be NULL. Modify 24091 to use group_exitchild to get the pointer of recent exited child. 24092 From Yang ChungFan. 24093 24094 * File System/Block and MTD Drivers: 24095 24096 - MMC/SD: Fixes bug where thread gets deadlocked due to recursive call 24097 and addresses comment regarding events. When initializing the 24098 MMCSD, if we are being told there is a card, but we fail to 24099 initialize it, we should not re-register for an insertion event as 24100 this will immediately cause us to call in again. Instead, we should 24101 register for a removal event and wait for the card to be removed and 24102 re-inserted. From Anthony Merlino. 24103 24104 * Networking/Network Drivers: 24105 24106 - UsrSock: Fix debug logs and remove DEBUGASSERT from 24107 usrsockdev_do_request(). In a client mode, socket() will be the 24108 first request for usrsockdev_do_request(). However, in a server 24109 mode, the first request to accepted sockets will be recv() or other 24110 which depend on applications. So I think we should remove thi 24111 DEBUGASSERT from usrsockdev_do_request(). From Masayuki Ishikawa. 24112 - ICMPV6 Autoconfig: Use ntohs() to convert IPv6 address from 24113 network to host order int network debug output. From Bernd Walter. 24114 - TCP Buffering: Fix TCP buffer send deadlock in iob_copyin() when 24115 IOB buffers are exhausted and network lock is taken. From 24116 Valmantas Paliksa. 24117 - TCP Close: Fix TCP active close in inet_close.c. In previous 24118 implementation, FIN packet was not sent when a socket is actively 24119 closed (e.g. telnetd or webserver) without SO_LINGER. This issue 24120 happens because the socket closing sequence waits for the 24121 status.cl_sem only if lingering timeout is set. However, in many 24122 server use-cases, SO_LINGER is not usually set and even in these 24123 cases, FIN packet must be sent correctly. This changes the logic 24124 in inet_close.c so that it can wait for status.cl_sem regardless 24125 of SO_LINGER. Instead, if SO_LINGERis set, it waits for the 24126 semaphore with timeout option. From Masayuki Ishikawa. 24127 - UDP: Fix C89 compatibility problem. Empty initializers are not 24128 permitted. Caused eZ80 build failure. From Gregory Nutt. 24129 - Telnet: Fix a C89 non-compliance that was breaking the eZ80 build. 24130 From Gregory Nutt. 24131 24132 * Wireless/Wireless Drivers: 24133 24134 - NRF24L01: Fix NRF24L01_NCMDS in ioctl.h. The last one in 24135 nrf24l01.h is _WLCIOC(NRF24L01_FIRST + 15) From Masayuki Ishikawa. 24136 - NRF24L01: Fix PIPENO/PKTLEN bitmask in RX FIFO header. In RX FIFO 24137 header, the first byte should use 5 lsb to store PKTLEN and 3 msb 24138 to store PIPENO. However, FIFO_PIPENO_SHIFT was set to 4 which 24139 causes the lsb of pipe number to interfere with the received packet 24140 size stored in the FIFO. This fix RX corruption when using pipe 24141 number > 0. From Federico Braghiroli. 24142 24143 * Graphics/Display Drivers: 24144 24145 - Raising Windows: Fix a critical list handling bug in the graphics 24146 system. When a lower-level window was raised while a model window 24147 was in place, then list corruption could occur. From Gregory Nutt. 24148 24149 * Common Drivers: 24150 24151 - Serial: Limit the number of times that the poll semaphore is 24152 incremented. From Dave Marples. 24153 - USB Host: Remove duplicate const in USB Host files. From Adam 24154 Porter. 24155 - USB Host Composite: Class-specific descriptors were not available 24156 if the interface is part of a composite device, since only interface 24157 and endpoint descriptors are copied by usbhost_copyinterface(). 24158 This change will copy any class-specific interface descriptors for 24159 use in downstream class drivers. The loop was aborting due to 24160 finding two interface descriptors back-to-back. From Adam Porter. 24161 - USB Host Composite: The cfgdesc pointer was initialized after the 24162 buffer had been advanced, so it was not pointing where it should. 24163 The totallen operations at the end of the function ended up 24164 overwriting memory belonging to the first copied interface 24165 descriptor. From Adam Porter. 24166 - USB MSC: Fix usbmsc_exportluns declaration. Fixes the following 24167 error "...undefined reference to `usbmsc_exportluns'". From Alin 24168 Jerpelea. 24169 24170 * Architecture Common: 24171 24172 - Rename all arch/<family>/src/<chip>/chip directories to 24173 arch/<family>/src/<chip>/hardware. This eliminates a name collision 24174 that is usually harmless but does cause problems at the time. The 24175 problem is because the include path includes '.' and 'chip/.', 24176 therefore an inclusion like '#include <chip/mcu_header.h' can be 24177 ambiguous if a file named mcu_header.h exists in both at both 24178 arch/<family>/src/<chip>/chip and at arch/<family>/src/chip/chip. 24179 From Gregory Nutt. 24180 24181 * Board Common: 24182 24183 - Default Configurations: Update configurations for changes to 24184 apps/netutils/netinit configuration. MAC address configuration 24185 was represented by type long long. That is a problem for 24186 architectures that do not support type long long. Replaces by 24187 two long configuration items. From 24188 Gregory Nutt. 24189 - Default Configurations: Change CONFIG_NSH_MACADDR to 24190 CONFIG_NETINIT_MACADDR From Masayuki Ishikawa. 24191 - Default Configurations: Fix mac address settings for RNDIS. 24192 Recently CONFIG_NETINIT_MACADDR_2 and CONFIG_NETINIT_MACADDR_1 were 24193 newly introduced instead of CONFIG_NETINIT_MACADDR. This change 24194 conforms to this change. From Masayuki Ishikawa. 24195 - Default Configurations: Kconfig files should not select 24196 SCHED_WORKQUEUE since that is really only is only the logical OR if 24197 SCHED_LPWORK and SCHED_HPWORK. Selecting it has no effect other 24198 than to produce an erroneous configuration. From Gregory Nutt. 24199 - Linker Scripts: Make sure sections are aligned to 32-bits in all LD 24200 linker scripts. This fixes and issues noted specifically for the 24201 SAMD21 by Bernd Walter, but should be applicable to all other LD 24202 scripts as well. 24203 - Linker Scripts: Add . = ALIGN(4); before every .data section, 24204 add . = ALIGN(4); before every ARM.extab section, add . = ALIGN(4); 24205 before every definition of __exidx_start, add . = ALIGN(4); before 24206 every .init_section. Convert TABs to spaces in all ld linker 24207 scripts. This just makes things easier to modify with scripts 24208 because the files are more consistent. From Gregory Nutt. 24209 - configs/Board.mk: Cannot call $(AR) directly. That works only with 24210 GCC. It must, instead use the ARCHIVE command from Config.mk as do 24211 other Makefiles. From Gregory Nutt. 24212 24213 * MIPS32: 24214 24215 - Fix a copy-paste error. On vfork, the GP register was being set to 24216 the new SP value vs. the context GP value. NOTED in Bitbucket issue 24217 155. From Gregory Nutt. 24218 - An older commit used CP0 register definitions that were not defined 24219 in the NuttX cp0.h header file. Probably these were from the 24220 Microchip hacked up GCC toolchain but are not generally available 24221 outside that toolchain. Fix: Add definitions to NuttX cp0.h header 24222 file. From Gregory Nutt. 24223 24224 * Microchip PIC32MZ Drivers: 24225 24226 - PIC32MZ GPIO: Use LAT instead of PORT when writing. From Ouss4. 24227 24228 * Microchip/Atmal SAM3/SAM4 Drivers: 24229 24230 - SAMD2/L2: Correct TC register bit field definitions used with 24231 TC_CTRLBCLR and TC_CTRLSET registers. From Bernd Walter. 24232 24233 * NXP LPC17xx Boards: 24234 24235 - LPC17xx PROTECTED: On the LPC1769 there are two 16 KiB AHB SRAM 24236 blocks, which are mapped back to back at physical address 0x2007C000 24237 and 0x20080000 (i.e. right below and right above a 512 KiB boundary). 24238 Memory from those two blocks is considered continuous when assigned 24239 to a heap. In the protected build mode, when the memory protection 24240 unit is used, though, it must be split into two MPU regions. This 24241 is because MPU regions must be naturally aligned, and the 32KiB 24242 continuous address space of the two 16KiB AHB SRAM blocks does not 24243 start at an address divisible by 32KiB. The only other 24244 configurations that use protected build mode on lpc17xx are 24245 currently open1788/knsh and open1788/knxterm. The LPC1788 has the 24246 AHB SRAM blocks mapped more sanely (from an MPU region point of 24247 view), which is probably why no problems emerged here. Both still 24248 compile with my change and other than wasting an MPU region (which 24249 would otherwise remain unused) should work fine. That said, I 24250 have no hardware to confirm. From Michael Jung. 24251 24252 * NXP LPC54xx Boards: 24253 24254 - LPCXpresso-LPC54628: Modify the TWM configurations to properly 24255 inject keyboard data. This way, in the case of multiple NxTERMs, 24256 only the NxTerm at the top of the hierarchy gets the keyboard input. 24257 Otherwise, it is not possible to use multiple NxTerms with each the 24258 keyboard input going to a different NxTerm window. From Gregory 24259 Nutt. 24260 24261 * NXP i.MXRT Drivers: 24262 24263 - i.MXRT Serial: Fix serial TIOCSINVERT From David Sidrane. 24264 - i.MXRT USDHC: USDHC Stopgap Fix for build breakage From David 24265 Sidrane. 24266 - i.MXRT USDHC: Fix compiler error for CONFIG_IMXRT_USDHC1 && 24267 !CONFIG_IMXRT_USDHC2 From David Sidrane. 24268 24269 * On Semiconductor LC823450: 24270 24271 - LC823450-XGEVK: Remove CPU assignment for LPWORK. This change will 24272 reduce audio under-run when running dvfs auto mode. From Masayuki 24273 Ishikawa. 24274 24275 * SiLabs EFM32 Drivers: 24276 24277 - EFM32 USB Host: Apply Adam Porter's STM32 fix to EFM32 which has 24278 the same IP. From Gregory Nutt. 24279 24280 * STMicro STM32: 24281 24282 - STM32F1 Pinmap: Fix names for complementary PWM outputs From 24283 Mateusz Szafoni. 24284 - STM32L4: If SRAM3 is used as heap, do not power it off in stop 2 24285 mode. From Juha Niskanen. 24286 24287 * STMicro STM32 Drivers: 24288 24289 - STM32 ADC: Fix a compilation error when verbose analog debugging is 24290 enabled for the STM32 ADC. not all STM32s have an SQR4 register. 24291 From rajan gill. 24292 - STM32 PWM: Fix pulse count for the number of counts greater than 128. 24293 From Mateusz Szafoni. 24294 - STM32 USB OTG FS/HS Host: In stm32_ctrlout() in the HS and FS host 24295 drivers, the data buffer isn't sent. This patch passes the buffer 24296 and buflen to the stm32_ctrl_senddata() function. With this change, 24297 I am able to send MBIM control messages to my USB modem, and read the 24298 response. From Adam Porter. 24299 - STM32L4 USB: Fix USB device PMA accesses. USB PMA accesses are 24300 done as 16-bit words on STM32L4 instead of 32-bit words on STM32L1. 24301 From Jussi Kivilinna. 24302 - STM32L4 OTG FS/HS: Fix constant using in comparison to determine 24303 endpoint is interrupt type. From Adam Porter. 24304 - STM32F7 OTG FS/HS: Fix constant using in comparison to determine 24305 endpoint is interrupt type. From Adam Porter. 24306 - STM32H7 PWM: Fix pulse count for the number of counts greater than 128. 24307 From Mateusz Szafoni. 24308 - STM32H7 Serial: Fix error when SINGLEWIRE or 24309 CONFIG_STM32H7_SERIALBRK_BSDCOMPAT defined. From David Sidrane. 24310 - STM32H7 SPI: Correct a typo in condition compilation. From 24311 Jonathan Richner. 24312 - STM32H7 Timer: Fixed compile errors with TIM13, TIM14, TIM7. From 24313 David Sidrane. 24314 - STM32H7 USB OTG FS/HS: Fix constant using in comparison to determine 24315 endpoint is interrupt type. From Adam Porter. 24316 - STM32G0 Serial: Fix STM32G0 error when SINGLEWIRE or SERIALBRK_BSDCOMPAT 24317 defined (it reflects previous changes in STM32H7). From Mateusz Szafoni. 24318 24319 * STMicro STM32 Boards: 24320 24321 - Nucleo-L432KC: Shorten some long lines, fix i2c pinout. From 24322 Sebastien Lorquet. 24323 - STM32L476VG-Disco: Fix an error in defconfig files because a line 24324 in the rcS file was longer than the configured NSH command line. 24325 From Juha Niskanen. 24326 - STM32L4R9AI-Disco: Fix an error in defconfig files because a line 24327 in the rcS file was longer than the configured NSH command line. 24328 From Juha Niskanen. 24329 - OmnibusF4: Correct naming of a configuration variable for ROMFS. 24330 From Phil Coval. 24331 - Olimex-STM32-E407: Change initialization to match the way it is 24332 done with other boards. From Gregory Nutt. 24333 - Olimex-STM32-E407 SPI: Add SPI initialization logic. From Juan 24334 Flores. 24335 - STM32F4-Discovery ROMFS: Missing colon in declaration of local 24336 variable. From Phil Coval. 24337 - STM32F4-Discovery ROMFS: Correct naming of a configuration variable 24338 for ROMFS. From Phil Coval. 24339 - STM32F4-Discovery Build: Fix .ARM.exidx section overlap Source: 24340 https://stackoverflow.com/questions/30778614/arm-none-eabi-ld-section-arm-exidx-overlaps-section-data. 24341 From Alan Carvalho de Assis. 24342 - STM32F4-Discovery PROTECTED: Fix a problem with undefined symbol 24343 'abort' from GCC library in PROTECTED build. Fix by moving libgcc 24344 into recursive archive group between --start-group and --end-group. 24345 Other kernel/Makefiles suffer from this same issue From Gregory 24346 Nutt. 24347 - Nucleo-H743ZI SPI: Correct typos in function naming. From Jonathan 24348 Richner. 24349 24350 * TI AM335x: 24351 24352 - AM335x SYSCLK: Add a function to return a frequency of the system 24353 clock. From Gregory Nutt. 24354 - AM355x CM: Fix a typo in a macro name. From Gregory Nutt. 24355 - AM355x LCD: Fix a few typos. Add things needed by the LCDC driver. 24356 From Gregory Nutt. 24357 24358 * TI Tiva Drivers: 24359 24360 - Tiva Ethernet: Add a workaround for tiva with qemu. With qemu, 24361 tiva_ifup() hangs because Ethernet link status can not be set 24362 correctly. This change is a workaround to avoid this issue. From 24363 Masayuki Ishikawa. 24364 24365 * TI Tiva Boards: 24366 24367 - TM4C1294-Launchpad: Fix syntax error in oocd.sh script. From 24368 Nathan Hartman. 24369 24370 * ZiLOG Common: 24371 24372 - z80: up_addregion() must be prototyped in nuttx/mm/mm.h, not 24373 up_internal.h. Various name changes to better conform to the coding 24374 standard, naming conventions, and use by other architectures. From 24375 Gregory Nutt. 24376 24377 * ZiLOG Z80 Boards: 24378 24379 - z80sim: Remove unused function up_earlyserialinit() from serial 24380 driver. From Gregory Nutt. 24381 24382 * ZiLOG z16f ZNeo: 24383 24384 - z16f ZNeo: Replicate build changes make for eZ80 and z8 for ZNeo. 24385 From Gregory Nutt. 24386 - ZNeo compile fixes: Fix misuse of FAR which makes a difference on 24387 this platform. Be consistent in use of WDOG_ID type. ZDS-II doesn't 24388 like auto-conversions of struct wdog_s * to WDOG_ID (which is type 24389 struct wdog_s *). From Gregory Nutt. 24390 24391 * ZiLOG eZ80Acclaim!: 24392 24393 - eZ80: Fix eZ80 compile problems due to New ZDS-II toolchain and 24394 ongoing bit rot due to non-C89 code creeping into the core OS. From 24395 Gregory Nutt. 24396 - eZ80: Fix some backward conditional logic in Make.defs. From 24397 Gregory Nutt. 24398 - eZ80: Fix a logic error in vector initialization. From Gregory Nutt. 24399 24400 * C Library/Header Files: 24401 24402 - signal.h: Fix a C89 compliance problem that cause the eZ80 build to 24403 fail. Empty structure and unions are not accepted by the compiler. 24404 From Gregory Nutt. 24405 - wqueue.h: Allow definitions even if work queues are not enabled. 24406 This solves build failures when work queues are not enabled. From 24407 Gregory Nutt. 24408 - fixedmath.h: Regarding the single precision float to/from fixed 24409 point conversions in fixedmath.h, I believe the floating point 24410 literals should be appended with the letter 'f' to avoid (expensive) 24411 conversions from single to double precision, and thereby also avoid 24412 (expensive if done in SW) double point arithmetic (which is what is 24413 happening upon inspection of my disassembly). From rajan gill. 24414 24415 - stdio: Fix long long usage in all of the newer printf-related 24416 logic: The selection CONFIG_LIBC_LONG_LONG must be ignored if the 24417 architecture does not support long long types. From Gregory Nutt. 24418 - gm_time_r(): Spurious reorganization of a loop in gm_time_r() to 24419 work around and ZDD-II internal compiler error. Might be a little 24420 bigger now, but is also probably a more structured use of C. From 24421 Gregory Nutt. 24422 - Debug: For platforms whose CPP tool does not support a variable 24423 number arguments to pre-processor macros, we may still need to build 24424 the debug functions even when CONFIG_DEBUG_FEATURES is not selected. 24425 For example, __alert() may be needed if CONFIG_ARCH_STACKDUMP is 24426 set. From Gregory Nutt. 24427 24428 * Tools: 24429 24430 - tools/nxstyle.c: Fix error in conditional logic that was preventing 24431 detection bad brace alignment. Add logic to handle alignment of 24432 braces in data initializers which following slightly different 24433 indentation rules. From Gregory Nutt. 24434 - tools/mkexport.sh: The mcu sub-directory chip/ was renamed to 24435 hardware/ in late May of 2019. The mkexport.sh script that copies 24436 these files was not updated, however, until now. Noted by Alin 24437 Jerpelea. From Gregory Nutt. 24438 24439 * NSH Library: apps/nshlib: 24440 24441 - apps/nshlib: Fix all places where cle() and readline() are used. 24442 readline() returns EOF on a failure. cle() returns a negated errno 24443 value. Checking only for EOF causes failues to be missed (and 24444 infinite loops ensuing). From Valmantas Paliksa. 24445 - nshlib/nsh_parse.c: Fix a warning about an uninitialized variable 24446 from the ZDS-II compiler. From Gregory Nutt. 24447 - apps/nshlib/nsh_ddcmd.c: Seemingly nonsense change but somehow 24448 works around a compilation error using the ZDS-II toolchain. It 24449 was claiming that vtbl was undefined indd_outfopen(). From Gregory 24450 Nutt. 24451 24452 * Network Utilities: apps/netutils: 24453 24454 - apps/netutils/netinit: MAC address configuration was represented 24455 by type long long. That is a problem for architectures that do not 24456 support type long long. Replaces by two long configuration items. 24457 From Gregory Nutt. 24458 - apps/netutils/telnetd/telnetd_daemon.c: Fix a C89 violation that 24459 caused the eZ80 build to fail. From Gregory Nutt. 24460 - apps/netutils/json: Removed. Replaced with apps/netutils/cjson. 24461 From Gregory Nutt. 24462 24463 * Graphics Utilities: apps/graphics: 24464 24465 - apps/graphics/twm4nx: Fix an uninitialized variable that was 24466 causing toolbar buttons to randomly come up enabled or disabled. 24467 Remove some unused event definitions. From Gregory Nutt. 24468 - apps/graphics/twm4nx: Fix a calibration screen startup issue. 24469 Make an initial calibration screen optional. From Gregory Nutt. 24470 - apps/graphics/twm4nx: Revise logic to detect clicks on the 24471 background image. The original implementation had some side 24472 effects. From Gregory Nutt. 24473 - apps/graphics/twm4nx: Remove some remaining stuff from TWM that 24474 was never used. Menus need to close after the 'terminal' selection 24475 is made. Otherwise, the menu can become buried under a newly open 24476 menu and not easily recovered. From Gregory Nutt. 24477 - apps/graphics/twm4ndx: Add a 'critical' bit to the eventID. While 24478 resizing, all events will be ignore except those marked critical. 24479 From Gregory Nutt 24480 - apps/graphics/twm4nx: CBackground now brings up the main menu if 24481 the background image is clicked. This makes the behavior the same 24482 across all of the background except when an icon is clicked. From 24483 Gregory Nutt. 24484 - apps/graphics/twm4nx: Fix a bug in placement of icons on the 24485 desktop. When many windows are displayed, a bug in the looping logic 24486 could cause an infinite loop. From Gregory Nutt. 24487 - apps/graphics/twm4nx: Fix some errors found when enabling NX 24488 keyboard support. The most important being that the mouse and 24489 keyboard drivers need to be opened non-blocking. From Gregory Nutt. 24490 24491NuttX-8.1 Release Notes 24492------------------------ 24493 24494The 132nd release of NuttX, Version 8.1, was made on September 14, 2019, 24495and is available for download from the Bitbucket.org website. Note 24496that release consists of two tarballs: nuttx-8.1.tar.gz and 24497apps-8.1.tar.gz. These are available from: 24498 24499 https://bitbucket.org/nuttx/nuttx/downloads 24500 https://bitbucket.org/nuttx/apps/downloads 24501 24502Both may be needed (see the top-level nuttx/README.txt file for build 24503information). 24504 24505The major release version number is only incremented when there is a major 24506change to the OS that makes it more-or-less incompatible with preceding 24507versions. This release bumps the major version number from 7 to 8 due 24508primarily to a major reorganization in the what was the configs/ directory 24509in nuttx-7.31. That directory has been renamed boards/ and now has a 24510directory structure that mirrors the organization of the arch/ directory 24511for the most part: 24512 24513 board/ - Holds all board-related information 24514 board/<arch> - Holds board-related information for all boards that use 24515 the same CPU architecture. For example, all ARM-based boards will be 24516 found under board/arm 24517 board/<arch>/<chip> - Holds board-related information for all boards 24518 that use the same MCU chip family. For example, all STM32-based 24519 boards will be found under board/arm/stm32 24520 board/<arch>/<chip>/<board> - Holds board-related information for a 24521 specific board. This is analogous to the configs/<board> directory in 24522 nuttx-7.31. So, for example, the STM32F4-Discovery board support that 24523 was at configs/stm32f4disovery can now be found under 24524 boards/arm/stm32/stm32f4discovery. 24525 boards/<arch>/<chip>/<board>/<configs> - All configurations for a 24526 specific board can now be found together in this configs/ 24527 subdirectory. So, continuing the example, the STM32F4-Discovery NSH 24528 configuration can now be found at 24529 boards/arm/stm32/stm32f4discovery/configs/nsh. 24530 24531In additional, common MCU logic can be found at board/<arch>/<chip>/common 24532and MCU common drivers can be found at board/<arch>/<chip>/common. Related 24533changes include changes to tools/, comments, and documentation that depend 24534on the board directory structure. 24535 24536This re-organization is the work of Alin Jerpelea. Not only did Alin do 24537this major directory re-organization, but he ran the code standard 24538compliance tool and corrected every .c and .h file under boards/ so that 24539they all correctly follow the NuttX coding style. These changes were very 24540extensive and, hence, will not be addressed individually in the ReleaseNotes. 24541 24542You have to give Alin credit for his effort to take on really big jobs and 24543stick with it until it is finished. Kudos! 24544 24545A more constrained re-organization of the drivers/ directory was also 24546contributed by Augusto Fraga Giachero. Augusto reorganized some driver 24547directories to make better functional associations and also to make space 24548for a new set of RF-related drivers. 24549 24550Additional new features and extended functionality: 24551--------------------------------------------------- 24552 24553 * Core OS: 24554 24555 - POSIX Message Queues: Add a test to verify that message queue is 24556 closed by the same task group that opened it. If not, then list 24557 corruption would result. This test is only performed if 24558 CONFIG_DEBUG_FEATURES is enabled since it should not normally be an 24559 issue: It would be a strange programming practice to open a 24560 message queue in open task group, then close it in another. From 24561 ???. 24562 - Signal Notifications: Add configuration option to select either the 24563 high-priority or low-priority work queue for SIG_EVTHREA 24564 notifications. From ligd. 24565 - System Calls: In order to support built-in in function in protected 24566 mode, a task_spawn() system call must be supported. task_spawn() 24567 and posix_spawn() are NuttX OS interfaces. In PROTECTED and KERNEL 24568 build modes, then can be reached from applications only via a system 24569 call. Unfortunately this is overly complex because there is a (soft) 24570 limit of 6 parameters in a system call; task_spawn has seven 24571 parameters. This is a soft limit but still difficult to extend 24572 because it involves assembly language changes to numerous 24573 architectures. Better to get more creative. Rather than extend the 24574 maximum number of parameters across all architectures, I opted 24575 instead to marshal the seven parameters into a structure and pass 24576 only a single parameter: A pointer to the structure containing the 24577 seven marshaled parameters. From Gregory Nutt. 24578 - /etc/passwd and /etc/group: Improve the format of the /etc/passwd 24579 file as used in the sim:nsh configuration. It is now a little 24580 more similar to other systems and includes user and group IDs. Add 24581 also an /etc/group file to support future testing. From Gregory 24582 Nutt. 24583 - User/Group IDs: Implement 'real' setuid, getuid, setgid, and getgid 24584 interfaces is so configured (otherwise fall back to stubs that 24585 support only the 'root' user ID and group. Once set, these IDs will 24586 be inherited by all child task groups. From Gregory Nutt. 24587 - Debug Output: Add debug macros for contactless. The various 24588 contactless device drivers currently define device specific debug 24589 macros within their local header files. This patch adds generic 24590 ctls[info|warn|err] macros for the overall contactless subsystem to 24591 be used in future drivers. Ported the existing contactless device 24592 drivers to use these generic logging macros and fixed some logging 24593 bugs along the way. From Michael Jung. 24594 - IOB instrumentation. Introduces producer/consumer id to every IOB 24595 call. This is so that the calls can be instrumented to monitor the 24596 IOB resources and to collect usage statistics. From Anthony 24597 Merlino. 24598 - IOB ProcFS: Adding ProcFS support at /proc/iobinfo to show the data 24599 collected from the IOB instrumentation. From Anthony Merlino. 24600 - Versioning: Report GIT information via ProcFS. GIT info reported: 24601 branch, version, GIT hash, hostname, user, build date. Integrates 24602 into existing .version and ProcFS. From David Alessio. 24603 24604 * File System/Block and MTD Drivers: 24605 24606 - BinFS: The BinFS file system uses the same built-in library and 24607 built-in arrays as does NSH. The built-in arrays are simple name- 24608 value pairs that map built-in function names with the user-space 24609 entry point. In the FLAT build, the built-in arrays are available 24610 everywhere via the backdoor left open by the FLAT address space. 24611 In the PROTECTED build, however, the kernel must maintain its own 24612 reference to the user-space built-in array. This commit adds those 24613 kernel globals and a new boardctl(BOARDIOC_BUILTINS) that can be 24614 used by applications to the provide the built-in list reference to 24615 the kernel. From Gregory Nutt. 24616 - MMC/SD: Added support for MMC (eMMC) bigger than 2 GB (Tested with 24617 IMXRT1050EVKB and samsung eMMC 16GB). 24618 - AT24CSxx: Register a character driver for UUID of AT24CSxx chips. 24619 Allows the UUID to read as a file or displayed from an nsh prompt with: 24620 nsh> hexdump /dev/eeprom.uuid From David Alessio. 24621 - Macronix FLASH: Add support for 4-byte addressing on >128Mb 24622 Macronix flash parts From jjlange. 24623 - MX25Rxx: Add support for 512B sectors. From Simon Piriou. 24624 - SST26: Accept the 16MBit Flash when reading the JEDEC-ID at 24625 initialization time. From Ouss4. 24626 24627 * Network/Network Drivers: 24628 24629 - IPv4 Options: Now handles reception of IPv4 packets with larger 24630 IPv4 headers containing options. From Gregory Nutt. 24631 - Sockets: Re-order the content of all address-family socket 24632 'connection' structures so that they begin with a common prologue. 24633 This permits better use of logic for different address family 24634 types. From Gregory Nutt. 24635 - TCP: Make RTO and WAIT_TIME configurable. This fix is not really 24636 correct: TCP RTO really should be calculated dynamically for each 24637 TCP connection: http://sgros.blogspot.com/2012/02/calculating-tcp-rto.html. 24638 From zhangyuan7. 24639 - IP Forwarding: Check if interface is up early on when forwarding to 24640 avoid extra work. As noticed in a previous wireless commit, when 24641 forwarding is enabled and a packet comes in, the packet is attempted 24642 to be sent on each other netdev without regard for whether it is in 24643 the UP state. Of course this is eventually caught, but it can be 24644 caught earlier to avoid unnecessary work, especially in the 6LoWPAN 24645 case where a useless packet conversion will occur. From Anthony 24646 Merlino. 24647 - RNDIS: Expose option to change the number of write requests that 24648 can be in flight. From Anthony Merlino. 24649 - GS2200M: Add UDP support. From Masayuki Ishakawa 24650 - GS2200M: Implement GS2200M_IOC_IFREQ IOCTL command. From Masayuki 24651 Ishikawa. 24652 - GS2200M: Enable NuttX's DHCP client instead of GS2200M's DHCP 24653 client. From Masayuki Ishikawa. 24654 - GS2200M: GS2200M now supports SIOCGIFHWADDR From Masayuki 24655 Ishikawa. 24656 24657 * Wireless/Wireless Drivers: 24658 24659 - IEEE802.15.4 Network Driver: Allow 64-bit prefix to be configurable 24660 when auto-configuring the IPv6 address during bring-up. Previously, 24661 only the link-local prefix fe80::/64 was used. Also, put the 24662 network in the DOWN state at the end of initialization. From 24663 Anthony Merlino. 24664 - IEEE 802.15.4 MAC: Adds support for energy detect. Adds support 24665 for energy detect by introducing a new radio call/callback, as the 24666 PHY layer is required to perform the energy detect. From Anthony 24667 Merlino. 24668 - IEEE 802.15.4 MAC: Adds support for getting/setting 24669 macMaxFrameRetries via IOCTL. Add get support for rxonidle 24670 attribute From Anthony Merlino. 24671 - IEEE 802.15.4 MAC: Move the global iobuffer into the macnet struct 24672 so that more than one macnet device can exist. From Anthony 24673 Merlino. 24674 - IEEE 802.15.4 MAC: Defer handling of extracting association 24675 response to LPWORK queue. From Anthony Merlino. 24676 - IEEE 802.15.4 Radios: Support dynamic FCS length. Adds 24677 IEEE802154_ATTR_PHY_FCSLEN. This change introduces 24678 IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to 24679 set/get the FCS length that's added to the end of the frame. One 24680 use case, in promiscuous mode, is to add back in the FCS of the 24681 received frame by increasing the iob->io_len by the FCS length. 24682 From Anthony Merlino. 24683 - Xbee: Support "WR" AT command for writing parameters to non- 24684 volatile memory. From Anthony Merlino. 24685 - Xbee: Add configuration option for setting the default prefix 24686 to use when bringing up the network and setting the IP address. 24687 From Anthony Merlino. 24688 24689 * Other Common Device Drivers: 24690 24691 - RTC: If the RTC time is successfully set, then update the current 24692 system time to match. From ligd. 24693 - ADT7320: Add support for the ADT7320 temperature sensor. From 24694 Augusto Fraga Giachero. 24695 - DAC7554: Add support to the DAC7554 digital-to-analog converter. 24696 From Augusto Fraga Giachero. 24697 - DAT-31R5-SP+: Add support to the DAT-31R5-SP+ digital attenuator. 24698 Creates a the new device driver directory drivers/rf/ to support 24699 drivers related to RF peripherals. It also adds support for the 24700 DAT-31R5-SP+ digital attenuator. From Augusto Fraga Giachero. 24701 - ISL29023: Add basic driver of ISL29023 ambient light sensor. The 24702 basic driver can set operational mode, range, and resolution. It 24703 can also read lux value in continuous mode. Interrupt and the alarm 24704 is not implemented. From Matous Pokorny. 24705 - SHT3x: Add Sensirion SHT3x driver. From Markus Bernet. 24706 24707 * Simulator: 24708 24709 - Simulator Build: Even though the simulation has no "chips", it 24710 needs to have CONFIG_ARCH_CHIP and chip sub-directories. Otherwise, 24711 we would have to treat it as a special case in the build system 24712 after the changes to the boards/ directory. From Gregory Nutt. 24713 24714 * Microchip PIC32MZ: 24715 24716 - PIC32MZ. Make the PLL input clock configurable. From Ouss4. 24717 24718 * ARMv7-M 24719 24720 - Add ARMv7-M setjmp/longjump functions. From David S. Alessio. 24721 24722 * NXP i.MXRT: 24723 24724 - i.MXRT Clocking: Enable TRACE clocks if the divider has been 24725 defined in the board's board.h file. From Dave Marples. 24726 24727 * NXP i.MXRT Drivers: 24728 24729 - i.MXRT QEncoder: Adds quadrature encoder driver for IMXRT. From 24730 Nicholas Chin. 24731 - i.MXRT uSDHC: This change completes SDIO support for IMXRT, and 24732 also adds support for WiFi using the AP6212A module based on Simon 24733 Piriou's rather excellent work. The patch should also address 24734 DavidS's concern about width setting for USDHC1 and 2. Testing of 24735 the WiFi is minimal so far but functionality is proven. I'm 24736 specifically not happy that the driver doesn't recover elegantly 24737 from a DMA data checksum failure, but that is an issue that can be 24738 dealt with in due course ... I'm trying to get the rest of the 24739 interfaces fleshed out and the hardware proven so it can go for pre- 24740 production build. I _think_ there's only Bluetooth and USB-device 24741 left to implement now. From Dave Marples. 24742 - i.MXRT uSDHC: IMXRT uSDHC driver cmd line reset logic modified. 24743 From Ivan Ucherdzhiev. 24744 24745 * NXP/Freescale Kinetis Drivers: 24746 24747 - Kinetis Serial: Add possibility to specify pull-up instead of 24748 open drain for serial single-wire mode. From Beat K�ng. 24749 24750 * NXP LPC17xx/40xx: 24751 24752 - LPC17xx/40xx Build: Cortex-M system reset is applicable to 24753 LPC17xx/40xx too. From Pavel Pisa. 24754 24755 * NXP LPC17xx/40xx Drivers: 24756 24757 - LPC17xx/40xx Ethernet: Follow the procedure listed in the 24758 LPC176x/5x User Manual when reading from and writing to the PHY's 24759 registers (section 10.11.14). I couldn't see any behavioral change 24760 after this commit, but nonetheless is a good practice to follow the 24761 manufacturer's recommended procedure. From Augusto Fraga Giachero. 24762 24763 * NXP S31K1xx: 24764 24765 - Added architecture support for the NXP S32K1xx family. Basic 24766 support includes the boot up logic, clock configuration, LPUART 24767 console, Systick timer, GPIO controls, and eDMA (unverified). 24768 24769 * NXP S31K1xx Drivers: 24770 24771 - S32K1xx eDMA Leverage eDMA logic from i.MXRT to S32K1XX. Appears 24772 to be the same IP but with fewer channels and features than the 24773 i.MXRT implementation. From Gregory Nutt. 24774 - S32K1xx LPUART: Bring in the LPUART from i.MXRT. It is the same 24775 IP. From Gregory Nutt. 24776 - S32K1xx SysTick: Bring in Cortex-M0+ SysTick and interrupt handling 24777 from samd2l2; bring in Cortex-M4F Systick and interrupt handling 24778 from LPC54xx. From Gregory Nutt. 24779 - S32K1xx GPIO: Bring in GPIO logic from Kinetis. Looks like similar 24780 IP. From Gregory Nutt. 24781 - S32K1xx Ethernet: Unverified port of the i.MXRT Ethernet driver to 24782 the S32K1xx. The i.MXRT uses the same IP. From Gregory Nutt. 24783 - S32K1xx LPSPI and LPI2C: Brings in the LPSPI and LPI2C peripheral 24784 drivers from the i.MXRT which used the identical IP. From Gregory 24785 Nutt. 24786 24787 * NXP S31K1xx Boards: 24788 24789 - S32K118EVB. This commit adds initial board support for the NXP 24790 S32K118EVB development board. Currently supports only a minimal 24791 NSH configuration. From Gregory Nutt. 24792 - S32K118EVB: Implement board support for on-board LEDs and buttons. 24793 This is taken from the Freedom-K66f with has the same LED and 24794 button configuration as the S32K116EVB and uses the same GPIO IP. 24795 LEDs, but not buttons, have have been verified. From Gregory Nutt. 24796 - S32K146EVB: Adds initial board support for the S32K146EVB 24797 development board. Currently supports a NSH configuration with a 24798 richer feature set than the minimal configuration of the S32K118EVB. 24799 From Gregory Nutt. 24800 - S32K146EVB: Add support for execution out of SRAM. This is helpful 24801 for bring-up when you want to avoid putting a lethal image in FLASH. 24802 From Gregory Nutt. 24803 - S32K148EVB: Add support for the NXP S32K148EVB development board. 24804 Very similar to the S32K146EVB but with more on-chip memory and 24805 hardware features. 24806 24807 * Sony CXD56xx 24808 24809 - CXD56xx: Migrate CXD56xx common code to the common/ directory: 24810 Boot code, FLASH code, I2C driver, UID. From Alin Jerpelea. 24811 - CXD56xx: Add SPH. The SPH is used by the ASMP implementation from 24812 the SDK. From Alin Jerpelea. 24813 24814 * Sony CXD56xx Drivers: 24815 24816 - CXD56xx: Add sensors connected to the SCU on Spresense board: 24817 o Avago APDS9930 Proximity and Ambient light Sensor. 24818 o Rohm BH1721FVC Ambient Light Sensor. 24819 o Rohm BH1745NUC Color Sensor. 24820 o Rohm BM1383GLV/BM1383AGLV Pressure Sensor. 24821 o Rohm BM1422GMV/BM1422AGMV Magnetic Sensor. 24822 o Bosch BMI160 Sensor support. 24823 o Bosch BMP280 Barometic Pressure Sensor. 24824 o Kionix KX022/KX122 Acceleration Sensor. 24825 o Murata LT1PA01 Proximity and Ambient light Sensor. 24826 o Rohm RPR0521RS Proximity and Ambient light Sensor. 24827 o BMI160: Add optional I2C address. 24828 From Alin Jerpelea. 24829 - CXD56xx: Add the sensor initialization for CXD56xx boards in the 24830 common board folder: 24831 o APDS9930: typo fix 24832 o cxd56_ak09912 initialization. 24833 o cxd56_bmi160 initialization. 24834 o cxd56_apds9960 initialization. 24835 o cxd56_bh1721fvc initialization. 24836 o cxd56_bh1745nuc initialization. 24837 o cxd56_bm1383glv initialization. 24838 o cxd56_bm1422gmv initialization. 24839 o cxd56_bmi160 initialization. 24840 o cxd56_bmp280 initialization. 24841 o cxd56_kx022 initialization. 24842 o cxd56_lt1pa01 initialization. 24843 o cxd56_rpr0521rs initialization. 24844 o cxd56_sensors initialization. 24845 o Backup Log driver. 24846 o crashlog driver. 24847 o Move gs2200m initialization. 24848 o Move ili9340 initialization. 24849 o Move lpm013m091a initialization. 24850 From Alin Jerpelea. 24851 24852 * Sony CXD56xx Spresense Board: 24853 24854 - Spresense: Enable SmartFS and UDP support From Masayuki Ishikawa. 24855 24856 * STMicro STM32: 24857 24858 - STM32F4 PLLI2S: Add support to enable the I2S Phase Locked Loop on 24859 STM32F427 and STM32F437 MCUs. From Michael Jung. 24860 24861 * STMicro STM32 Drivers: 24862 24863 - STM32 ADC: Add ADC calibration procedure for IP_ADC_V1. Tested on 24864 STM32F100, and it magically increased result accuracy. STM32F103 24865 has the same calibration procedure. I am not sure about others. 24866 From Matous Pokorny. 24867 - STM32 SPI: TI Synchronous Serial Frame Format. The SPI macros on 24868 STM32 MCUs now support the Texas Instruments Synchronous Serial 24869 Frame Format protocol (TI protocol). Defined a new SPIDEV_MODETI 24870 and add support for it in stm32_spi.c. From Michael Jung. 24871 - STM32 UART: Serial add HW HS on UART 4 & 5. From David Sidrane. 24872 - STM32 PWM: Configure multi-channel duty only if channel specified. 24873 This allows you to update duty cycle for a single channel. From 24874 Mateusz Szafoni. 24875 - STM32F7 Ethernet: Add a timeout on MAC reset From David Sidrane. 24876 - STM32F7 FLASH: Exposes stm32_flash_xxx functions. From Anthony 24877 Merlino. 24878 - STM32F7 PWM: Configure multi-channel duty only if channel specified. 24879 This allows you to update duty cycle for a single channel. From 24880 Mateusz Szafoni. 24881 - STM32F7 UART: Serial add HW HS on UART 4 & 5. From David Sidrane. 24882 - STM32H7 ADC: Fix internal channel numbers. From Markus Bernet. 24883 - STM32H7 BBSRAM: Add BBSRAM support. From David Sidrane. 24884 - STM32H7 DTCM: Port DTCM from F7 From David Sidrane. 24885 - STM32H7 I2C: Select ARCH_HAVE_I2CRESET in configuration. From 24886 David Sidrane. 24887 - STM32H7 PWM: Configure multi-channel duty only if channel 24888 specified. This allows you to update duty cycle for a single 24889 channel. From Mateusz Szafoni. 24890 - STM32H7 RCC: Fix RCC register definitions and typos for ADC/UART. 24891 From Markus Bernet. 24892 - STM32H7 RTC: Ported over F7 RTC. From David Sidrane. 24893 - STM32H7 SPI: Allow more clock sources. From David Sidrane. 24894 - STM32H7 UART: Serial add HW HS on UART 4 & 5. From David Sidrane. 24895 - STM32H7 UART: Fix typo in UART8 configuration. From Markus Bernet. 24896 - STM32H7 UID: Ported UID from F7 From David Sidrane. 24897 - STM32L4 PWM: Configure multi-channel duty only if channel specified. 24898 This allows you to update duty cycle for a single channel. From 24899 Mateusz Szafoni. 24900 - STM32L4 UART: Serial add HW HS on UART 4 & 5. From David Sidrane. 24901 24902 * STMicro STM32 Boards: 24903 24904 - B-L475E-IOT01A: Add mx25rxx memory chip and smartfs support in NSH 24905 configuration. From Simon Piriou. 24906 - LX_CPU: Add support for the PIKRON LX_CPU board. From Pavel Pisa. 24907 - Nucleo-F303RE: Add basic NSH configuration. From Mateusz Szafoni. 24908 - Nucleo-F303RE: Enable console on UART2 and set entry point to 24909 nsh_main() in the PWM configuration. From Mateusz Szafoni. 24910 - Nucleo-H743ZI: Add RTC support. From David Sidrane. 24911 - Nucleo-L432KC: Added GPIO drivers for use with /apps/examples/gpio. 24912 From Daniel P. Carvalho. 24913 - Nucleo-L432KC: Added Zero Cross sensor to nucleo-l432kc. From 24914 Daniel P. Carvalho. 24915 24916 * TI Tiva: 24917 24918 - Tiva: Add support for Tiva TM4C123AH6PM. From Nathan Hartman. 24919 - Tiva Configuration: Modify preprocessor logic to support 24920 configurations with no UART. Now similar to logic for other 24921 architectures. From Nathan Hartman. 24922 - Tiva Interrupts: Add handling for IRQs 128 thru 159. From Nathan 24923 Hartman. 24924 24925 * TI Tiva Drivers: 24926 24927 - TM4C QEncoder: Reinstate TM4C qencoder driver and expand its 24928 ioctls. Add TIVA_HAVE_QEI0, TIVA_HAVE_QEI1 as applicable to each 24929 ARCH_CHIP_TM4C12*. Rewrite tiva_qe_setup(). Replace tiva_qe_ppr() 24930 with tiva_qe_resetatppr(). Add tiva_qe_resetatmaxpos() and 24931 tiva_qe_resetatindex(). Add missing definitions: 24932 SIGMODE_QUADRATURE, SIGMODE_CLK_AND_DIR, SWAP_NO_SWAP, SWAP_PHA_PHB. 24933 Rename TIVA QEI ioctl QEIOC_PPR to QEIOC_RESETATPPR; add TIVA QEI 24934 ioctl identifiers QEIOC_RESETATMAXPOS, QEIOC_RESETATINDEX. From 24935 Nathan Hartman. 24936 24937 * TI Tiva Boards: 24938 24939 - TM4C1294-Launchpad: Enables /dev/userleds in board bring-up for 24940 tm4c1294-launchpad by calling userled_lower_initialize() in 24941 tm4c_bringup(). From Nathan Hartman. 24942 24943 * TI Tiva Drivers: 24944 24945 - Tiva GPTM timers: Implement 16-bit PWM mode. Add 24946 tiva_pwm16_sel_event() to choose GPTMCTL.TnEVENT value. Implement 24947 tiva_pwm_mode16(). This also involved numerous corrections to the 24948 16-bit timer logic. Add tiva_timer16pwm_setperiodduty() to set 24949 initial period, duty cycle, and enable interrupts if requested in 24950 GPTM peripheral. Interrupts are not enabled in NVIC until 24951 tiva_timer16_start() is called. Add tiva_timer16pwm_setduty() to 24952 update duty cycle at any time. Add new TIMER_FLAG_* configuration 24953 flags to enable configuring the 16-bit PWM feature. Extend type of 24954 "flags" in tiva_timer32config_s and tiva_timer16config_s from 8- to 24955 32-bits to allow more flags. From Nathan Hartman. 24956 24957 * Build System: 24958 24959 - Export Build: Export all variables/files to support architecture 24960 independent build against NSH. From Pavel Pisa. 24961 - Application Export: This change too build tools allows to export 24962 built-in applications registry into temporarily created directory 24963 where export archive content is prepared. If the Makefile in apps/ 24964 directory does not define export: target then error is print but 24965 export continues without interruption. It would be more logical to 24966 print warning but there is no way instruct apps make to not print 24967 error. From Pavel Pisa. 24968 - boards/Board.mk: Add support to pass dependency paths. From 24969 Gregory Nutt. 24970 24971 * Libraries/Header Files: 24972 24973 - libs/libc/libc.csv: Add some missing C library functions. From 24974 Pavel Pisa. 24975 - libs/libc/libc.csv: Add ioctl() to fs_ioctl() wrapper for varidic 24976 case. From Pavel Pisa. 24977 - libs/libc/builtin/: Moves shared built-in information out of 24978 binfmt/libbuiltin and into libs/libc/builtin where it can be shared 24979 with applications. This should permit built-in application in the 24980 PROTECTED build where binfmt/libbuiltin was not available in user 24981 space. From Gregory Nutt. 24982 - libs/libc/dirent/: Added alphasort() implementation, scandir() 24983 implementation and DT_* definitions to include/dirent.h. Apparently 24984 those definitions are not required by POSIX, but are part of 24985 4.3BSD and available in glibc as well. From Michael Jung. 24986 - libs/libc/grp/: Added stubbed implementations of getgrgid, 24987 getgrgid_r, getgrnam, getgrnam_r, and initgroups. These functions 24988 are essentially stubs pretending that NuttX supported groups and 24989 that the only configured group in the system was 'root' with gid 0. 24990 The intend is not to provide meaningful new features, but to ease 24991 porting of foreign source code to NuttX. From Michael Jung. 24992 - libs/libc/machine/arm/armv7-m/: Add Cortex M4F machine optimized 24993 fabsf and sqrtf. From David S. Alessio. 24994 - libs/libc/pwd/: Added stubbed implementations. Added stubbed 24995 implementations of getpwuid, getpwuid_r, getpwnam, and getpwnam_r. 24996 These functions are essentially stubs pretending that NuttX 24997 supported users and that the only configured user in the system 24998 was 'root' with uid 0. The intend is not to provide meaningful 24999 new features, but to ease porting of foreign source code to NuttX. 25000 From Michael Jung. 25001 - libs/libc/pwd and libs/libc/grp/: Modify to get user/group data 25002 from /etc/passwd and /etc/group if so configured. From Gregory 25003 Nutt. 25004 - libs/libc/stdio/: Add support for the size_t integer qualifier 'z' 25005 to the printf family. This is kind of tricky due the variety of 25006 sizeof(size_t) on different platforms. From David Sidrane. 25007 - libs/libc/unistd.h: Added stubbed implementations of setuid() and 25008 setgid(). These functions are essentially stubs pretending that 25009 NuttX supported users and groups and that the only configured user 25010 and group in the system were both 'root' with a uid and a gid of 0, 25011 respectively. The intent is not to provide meaningful new features, 25012 but to ease porting of foreign source code to NuttX. From Michael 25013 Jung. 25014 - libs/libc/unistd/: Add getuid() and getgid() stubs to match 25015 MichaelJung's setuid() and setgid(). From Gregory Nutt. 25016 - libc/libc/unistd/: Add stubs for geteuid(), getegid(), seteuid(), 25017 setegid(), setreuid(), and setregid(). NuttX does not currently 25018 support effective user/group IDs, but these stubs will support 25019 linkage of applications that expect these POSIX standard interfaces. 25020 From Gregory Nutt. 25021 25022 * Symbol Tables: 25023 25024 - NuttX provides lists of available syscalls and library functions and 25025 tools to process them. The lists can be used to build symbol table 25026 which allows runtime program loading which can reuse functions 25027 already compiled into NuttX system image. List processing, 25028 compilation and linking to the final system image has been possible 25029 only under manual control until now. Provided changes add option 25030 (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of 25031 available functions and syscalls automatically. The symbolic table 25032 is generated in form libsymtab.a which can be reused by application 25033 or directly pull in when "g_symtab" and "g_nsymbols" variables are 25034 requested by EXECFUNCS configuration. I have tried to follow 25035 mechanisms for library compilation in different kernel protection 25036 modes but tested only flat no-MMU build. The basic assumption is 25037 that this library and libraries providing syscall stubs and C- 25038 library functions are available in user-space context and initial 25039 application (usually NSH) registers the symbol table through IOCTL. 25040 The table can be reused then by another applications in their 25041 address space as kernel allows. Simple for flat or protected mode, 25042 I am not sure if really support in MMU mode. It is highly probable 25043 that I have made some mistake, overlooked something, but the 25044 functionality is optional (should not cause troubles in any mode if 25045 disabled) and main purpose is to lower memory overhead when more 25046 applications are loaded on memory constrained system which usually 25047 use direct kernel calling without protection or address space 25048 separation. If the table should be provided by kernel to 25049 applications then makefiles has to be adjusted. From Pavel Pisa. 25050 25051 * Tools: 25052 25053 - tools/: Change preferred argument of configurations tools to use 25054 ':' as the delimiter between <board-name> and <config-name>. This 25055 is to emphasize that this is not a path; it is configuration 25056 specification. The legacy '/' delimiter is still supported but 25057 not recommend and not advertised. Updated configurations 25058 instructions in README.txt files to show ':' delimiter vs '/' 25059 delimiter. Update all configuration-related tools to accept ':' 25060 separator between board and configuration name. From Gregory Nutt. 25061 25062 * apps/ General: 25063 25064 - Makefile: Added support for application-specific export target. 25065 Used by nuttx/tools/mkexport.sh. From Pavel Pisa. 25066 - apps/builtins: Move apps/builtins/builtin_forindex.c to 25067 nuttx/libs/libc/builtin since it is required by kernel logic as 25068 well. Other changes account for movement of builtin.h from 25069 nuttx/include/nuttx/binfmt/built.h to nuttx/include/lib/builtin.h. 25070 From Gregory Nutt. 25071 25072 * Examples/Tests: apps/examples: 25073 25074 - apps/examples/uid: Demo used to verify PASSWD and GROUP interfaces. 25075 From Gregory Nutt. 25076 - apps/examples/webserver/: Initialilze network and run forever only 25077 if not built-in app. Infer from CONFIG_NSH_BUILTIN_APPS if we are a 25078 NSH built-in app or not. If built-in app (CONFIG_NSH_BUILTIN_APPS 25079 defined) then we assume network is initialized prior to webserver 25080 starting and we exit on webserver failure. If running standalone 25081 (CONFIG_NSH_BUILTIN_APPS is undefined) then behavior is unchanged: 25082 webserver initializes network and runs forever. From Nathan Hartman. 25083 25084 * Network Utilities: apps/fsutils: 25085 25086 - apps/fsutils/passwd: Handle the improved the format of the 25087 /etc/passwd file. It is now a little more similar to other systems. 25088 From Gregory Nutt. 25089 25090 * Network Utilities: apps/netutils: 25091 25092 - apps/netutils/dhcpc: Add host name support to DHCP client. From 25093 Masayuki Ishikawa. 25094 25095 * Network Utilities: apps/wireless 25096 25097 - apps/wireless/ieee802154/i8sak: I8sak improvements: (1) Adds 25098 support for getting/setting maxretries and promsicuous mode from 25099 i8sak, (2) Fixes a build warning and handles a few cases where a 25100 fault can occur due to not catching missing arguments. From 25101 Anthony Merlino. 25102 - apps/wireless/ieee802154/i8sak: Allow setting the endpoint PAN ID. 25103 From Anthony Merlino. 25104 - apps/wireless/ieee802154/i8sak: Adds support for energy scan result 25105 printout. From Anthony Merlino. 25106 - apps/wireless/ieee802154/i8shark: Adds support for intentionally 25107 suppressing passing the FCS so that Wireshark doesn't try to 25108 validate it. From Anthony Merlino. 25109 - apps/wireless/ieee802154/libmac: Adds support for getting/setting 25110 the FCS length From Anthony Merlino. 25111 - apps/wireless/gs2200m: Add UDP support to the GS2200M driver. From 25112 Masayuki Ishikawa. 25113 - apps/wireless/gs2200m: Add DHCP client handling in ioctl_request(). 25114 From Masayuki Ishikawa. 25115 - apps/wireless/gs2200m: ioctl_request() supports SIOCGIFHWADDR. 25116 From Masayuki Ishikawa. 25117 25118Bugfixes: 25119--------- 25120Only the most critical bugfixes are listed here (see the ChangeLog for a 25121more complete list of bugfixes and for additional, more detailed bugfix 25122information): 25123 25124 * Core OS: 25125 25126 - Priority Inheritance: Fix a race in telnet with PRIORITY_INHERITANCE 25127 and SCHED_HPWORK. Sometimes causes an assertion to fire incorrectly. 25128 From David S. Alessio. 25129 - Task Groups: Correct some naming. The NuttX task groups have been 25130 using the acronym 'gid' and also the type 'gid_t' for the the task 25131 group ID. That is incorrect. Than naming is reserved for use with 25132 group permissions. So these were all named to grpid and grpid_t so 25133 that it is clearer that these refer to NuttX task group IDs, and not 25134 to group permissions. From Gregory Nutt. 25135 - Task Termination: nxtask_signalparent() in task_exithook.c may 25136 invalidate the group's parent task ID (tg_ppid) too soon. The 25137 tg_ppid field is use only to remember the parent tasks ID so that it 25138 can send the SIGCHLD signal to it. So it must stay valid until 25139 SIGCHLD has been sent. In nxtask_signalparent(), it calls 25140 nxtask_sigchild() to send SIGCHLD to the parent, then invalidates 25141 tg_ppid. That would be okay, except that the SIGCHLD is only sent 25142 when the last member of the group terminates. That is incorrect; 25143 tg_ppid can be invalidated too soon and, as a consequence, SIGCHLD 25144 would never be sent. Noted by Jeongchan Kim in the Google group: 25145 https://groups.google.com/forum/#!topic/nuttx/SXd8fVwVKBk From 25146 Gregory Nutt. 25147 - sched_get_rr_interval(): sched_get_rr_interval() should return 25148 {0,0} if round-robin scheduling is not selected for the task. From 25149 Gregory Nutt. 25150 - SMP Type Collision: The non-standard, non-portable type cpu_set_t 25151 was created specifically to support the NuttX internal, SMP 25152 implementation. Any resemblance to any other cpu_set_t would be 25153 purely coincidental. However it appears that that coincidence has 25154 occurred. cpu_set_t has an equivalent, non-standard, non-portable 25155 type in the GNU C library. Compilation of libgnat expects this 25156 non-standard type to be defined. Who am I to stand in the way of 25157 progress? This commit removes the conditioning on CONFIG_SMP so 25158 that cpu_set_t is typed (as a uint8_t) even if CONFIG_SMP is not 25159 defined. Reference: Bitbucket issue 164. From Gregory Nutt. 25160 - Binary Loader: Change some debug macros from berr() to binfo() 25161 when dumping module data. The report of problems is important 25162 during development but when it enables complete informative output 25163 about load binaries then the important information can be easily 25164 overlooked. The huge output sent to serial terminal slows loading 25165 significantly as well. From Pavel Pisa. 25166 - Power Management: Fix g_pmcount 16-bits overflow when 25167 CONFIG_PM_XXENTER_COUNT set big value. From ligd. 25168 - Timekeeping: Fix cases in time conversion that must be >= 25169 NSEC_PER_SEC, not > NSEC_PER_SEC. From Gregory Nutt. 25170 25171 * File System/Block and MTD Drivers: 25172 25173 - opendir(): opendir() set errno to a negative value in one error 25174 case. From Michael Jung. 25175 - SmartFS: Update smartfs smart_scan() function. From Simon Piriou. 25176 - ProcFS: Add missing LF to cpuload procfs output From David Alessio. 25177 - MMC/SD: Copy/paste error fix in the SDIO-based block driver for 25178 MMC. From Ivan Ucherdzhiev. 25179 - MMC/SD: Correct a misplaced #endif in the SDIO-based driver. From 25180 Gregory Nutt. 25181 25182 * Networking/Network Drivers: 25183 25184 - Ethernet Configuration: Ethernet packet buffer size cannot be 25185 permitted to go below 1294 if IPv6 is selected. From Gregory Nutt. 25186 - TCP RST: Fix outgoing RST packet with wrong ack number. From 25187 biantao. 25188 - TCP Close: Fix TCP close flow; free the connection after all TCP 25189 close process finished. From zhangyuan7. 25190 - UDP Broadcast: Remove net stack dependency from CONFIG_NET_BROADCAST. 25191 This change allows us to use CONFIG_NET_BROADCAST without network 25192 stack (i.e. usrsock application can use broadcast) From Masayuki 25193 Ishikawa. 25194 - UDP: Fixes a UDP send copy-paste error in the new SO_LINGER code: 25195 CONFIG_TCP_NOTIFIER to CONFIG_UDP_NOTIFIER. From Juha Niskanen. 25196 - TCP and UDP: Fix errors in the new implementation of SO_LINGER. 25197 The tcp_drain() and udp_drain() functions were casting the working 25198 argument to the wrong type, resulting in hangs and abnormal 25199 behavior. There is a complexity in the TCP drain logic when the 25200 remote peer closes the socket before all Tx data has been flushed. 25201 Sometimes we are not notified of this case and wait the entire 25202 timeout unnecessarily. There is a workaround in place in 25203 tcp_txdrain(), but this really should be revisited. From Gregory 25204 Nutt. 25205 - 6LoWPAN: Removes unnecessary conversions that were happening due to 25206 a misunderstanding of byte ordering with EUI-64. From Anthony 25207 Merlino. 25208 - RNDIS: Fix issue with DEBUGASSERT when using composite device and 25209 endpoint numbers not being the default. From Anthony Merlino. 25210 25211 * Wireless/Wireless Drivers: 25212 25213 - wireless network devices: Attach radio to d_buf before registering 25214 device to handle forwarding case. When CONFIG_NET_IPFORWARD is 25215 enabled, and CONFIG_NET_6LOWPAN is being used, a packet that 25216 attempts to get forwarded on the 6LoWPAN interface will require 25217 that the radio's buffer be attached to d_buf. Otherwise an assertion 25218 will fire. The underlying "radio" in this case is the 25219 mac802154_netdev. This behavior has probably not been observed 25220 because the buffer is normally attached in the periodic txpoll 25221 worker. However, in my case, the 6LoWPAN interface was not UP yet, 25222 and therefore the worker hadn't run yet. From Anthony Merlino. 25223 - IEEE 802.15.4 MAC: Fixes issues with extended address. 1) Extended 25224 address should be read-only. 2) Extended address should be placed 25225 in frame in "reverse-canonical" order. The extended address is a 25226 read-only attribute and thus an attempt to write the extended 25227 address should be denied. Instead, the extended address should 25228 really be either set by the PHY/radio itself, or provided at board 25229 bring-up time to the radio layer. The MAC layer now pulls in the 25230 extended address from the radio any time the MAC is reset. The 25231 extended address is also supposed to be sent in the frame in 25232 reverse-canonical order. This is very confusing in the standard and 25233 it wasn't until I realized it was backwards in Wireshark that I 25234 researched this further. Searching online I find documents from the 25235 committee for suggestions/feedback on the future standard. It isn't 25236 in the 2015 standard but a newer version of the standard will 25237 presumably clarify this. It says that the extended address should be 25238 written in reverse-canonical form, meaning the OUI comes last, not 25239 first inside the frame. From Anthony Merlino. 25240 - IEEE 802.15.4 MAC: Frame Version should have been 1, but was being 25241 set to 3 when payload exceeds version 0 capabilities. Adds warning 25242 to build to indicate what is noted in the menu for 25243 CONFIG_MAC802154_NTXDESC From Anthony Merlino. 25244 - IEEE 802.15.4 MAC: Fixes issue where the txdesc's ackreq flag was 25245 not being set, despite the frame containing a Frame Control field 25246 with ACKREQ bit set. From Anthony Merlino. 25247 - Xbee: Fix logic to prevent deadlock scenario when there are no 25248 available IOBs From Anthony Merlino (2018-12-21). 25249 - Xbee: Change assumption about destination address mode for incoming 25250 frames. If a short address has been assigned to our radio, then 25251 assume we were addressed using that. Otherwise we were addressed 25252 using our extended address. From Anthony Merlino. 25253 - Xbee: Initialize the short address to the unspecified address and 25254 query for the extended address on initialization. From Anthony 25255 Merlino. 25256 - Xbee: Adds CONFIG_XBEE_LOCKUP_WORKAROUND option and corresponding 25257 logic to workaround an issue where the XBee locks up and stops 25258 responding. This typically happens when there is a lot of data 25259 being received over the link. When the XBee stops responding, many 25260 times, querying the XBee kicks it out of this state. However, 25261 occasionally the XBee is completely locked up and the XBee has to 25262 be reset. This change handles these conditions by periodically 25263 (if not naturally occurring) querying the XBee. If during any 25264 query, the XBee does not respond within a certain number of 25265 attempts, the XBee is reset. From Anthony Merlino. 25266 - Xbee: Cancel query timeout upon receiving the expected response. 25267 Add protection for race condition that can cause association 25268 timeout to continue firing repeatedly From Anthony Merlino. 25269 - Xbee: Detect lockup and reset XBee in xbee_req_data From Anthony 25270 Merlino. 25271 - Xbee: Fixes one instance of the use of IOBUSER_WIRELESS_MAC802154 25272 which isn't available without the software MAC layer. Instead we 25273 use IOBUSER_WIRELESS_RAD802154 throughout the whole driver since it 25274 is always available when IEEE 802.15.4 support is enable. From 25275 Anthony Merlino. 25276 25277 * Common Drivers: 25278 25279 - pipes: Use inode reference counter instead of device reference 25280 counter to handle dup(). I found that if I dup() a pipe, the 25281 reference counter d_refs is not increased. If I close any of the 25282 fd, backed by the same pipe, the pipe will be freed. This causes 25283 any further usage on the fd referencing a non existent pipe. This 25284 change uses the inode reference counter, which is properly 25285 maintained during dup(). From Yang ChungFan. 25286 - SPI Bitbang: Fix build error when the SPI bitbang variable width 25287 support is enabled. From Augusto Fraga Giachero. 25288 - GPIO Lower Half: Remove limitation when pintype > 25289 GPIO_INTERRUPT_PIN. From ligd. 25290 25291 * ARMv4/ARMv5 25292 25293 - Classic ARM7/ARM9: When performing stability test, the application 25294 would cause kernel crash. When I trace the stack, I find that 25295 register R1 has been changed, and its value is the same as register 25296 CPSR. In up_fullcontextrestore.S, the restoration of R0 and R1 is 25297 not atomic: 'msr cpsr r1 will enable interrupts and the recovery of 25298 r0 and r1 may be interrupted and the value or R1 may be changed. 25299 Fix is to use a single ldmia to restore R0, R1, and return via R15. 25300 From Loyen Wang. 25301 25302 * ARMv7-A 25303 25304 - ARMv7-A: Fix typo and missing quotation for ARMv7-A. From Oki 25305 Minabe. 25306 - ARMv7-A: Fix double increment in armv7-a's 25307 arm_addrenv_destroy_region(). From Oki Minabe. 25308 - ARMv7-A: Fix L2 page table mask for ARMv7-A page allocator. From 25309 Oki Minabe. 25310 25311 * ARMv7-M 25312 25313 - Interrupts. Removes the architecture-common 25314 CONFIG_ARCH_INT_DISABLEALL configuration option (but which was 25315 supported only by ARMv7-M). In the normal course of things, 25316 interrupts must occasionally be disabled using the up_irq_save() 25317 inline function to prevent contention in use of resources that may 25318 be shared between interrupt level and non-interrupt level logic. 25319 Now the question arises, if we are using BASEPRI to disable 25320 interrupts and have high priority interrupts enabled 25321 (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except 25322 SVCall (we cannot disable SVCall interrupts). Or do we only disable 25323 the "normal" interrupts? If we are using the BASEPRI register to 25324 disable interrupts, then the answer is that we must disable ONLY the 25325 "normal interrupts". That is because we cannot disable SVCALL 25326 interrupts and we cannot permit SVCAll interrupts running at a 25327 higher priority than the high priority interrupts (otherwise, they 25328 will introduce jitter in the high priority interrupt response time.) 25329 Hence, if you need to disable the high priority interrupt, you will 25330 have to disable the interrupt either at the peripheral that 25331 generates the interrupt or at the NVIC. Disabling global interrupts 25332 via the BASEPRI register cannot effect high priority interrupts. 25333 From Gregory Nutt. 25334 - ARMv7-M Priorities: In the 'normal' case, the priority of the 25335 SVCALL interrupt was the same as the priority of the high priority 25336 interrupt. This means that SVCALL interrupt processing can defer 25337 the high priority interrupt and result in the jitter in that 25338 interrupt response. Fix is to raise the priority of the high 25339 priority interrupt above the priority of the SVCALL interrupt. 25340 Suggested by Nathan Hartman. From Gregory Nutt. 25341 25342 * Microchip i.MXRT Drivers: 25343 25344 - i.MXRT ENC: Fix some errors in register bit definitions. Noted by 25345 Arie de Muijnck. From Gregory Nutt. 25346 - i.MXRT LPI2C: Slave addresses are now correctly shifted when 25347 sending START. TX/RX FIFOs now discarded on error to prevent FIFO 25348 underflow errors. Fixes error checking to use priv structure and 25349 removes checking of BBF flag as it is not an error. From Nicholas 25350 Chin. 25351 25352 * Microchip PIC32MZ Drivers: 25353 25354 - PIC32MZ SPI: Fix SPI Mode selection. CKE is the inversion of the 25355 CPHA. From Ouss4. 25356 25357 * Microchip/Atmel SAMD2x/SAML2x Drivers: 25358 25359 - SAMD2/L2 I2C: Correct time calculation. From Bernd Walter. 25360 25361 * Microchip/Atmel SAM3/SAM4: 25362 25363 - SAM3/4: Add missing DMA configuration Kconfig setting. From Bernd 25364 Walter. 25365 25366 * NXP LPC17xx/40xx Drivers: 25367 25368 - LPC17xx/40xx ADC: Only use PCLKSEL0 for ADC on LPC176x family. 25369 From jjlange. 25370 - LPC17xx/40xx Ethernet: Set speed back to 10Mbps if 10Mmbps link 25371 negotiated. From Augusto Fraga Giachero. 25372 - LPC17xx/40xx I2C: Abort I2C transfers if a timeout has occurred. 25373 If a timeout has occurred in the middle of a I2C transfer, the next 25374 I2C interrupt should abort any transfers and send a stop condition 25375 to the corresponding I2C bus. Failure to do so will result in 25376 memory corruption / undefined behavior as priv->msgs points to a 25377 region of memory it doesn't owns anymore after lpc17_40_i2c_start 25378 returns. From Augusto Fraga Giachero. 25379 - LPC17xx/40xx I2C: Calculate the appropriate timeout for I2C 25380 transfers. Depending on the bus frequency and transfer size, I2C 25381 transactions can take quite a bit, so a fixed timeout is not a 25382 good solution. Calculating the timeout at run time poses some 25383 overhead but still better than aborting long transactions. From 25384 Augusto Fraga Giachero. 25385 25386 * NXP/Freescale Kinetis Drivers: 25387 25388 - Kinetis I2C: i2c transfer ensure correct result returned. 25389 kinetis_i2c_transfer released the mutex then fetched the state, 25390 this resulted in returning the correct results. From David 25391 Sidrane. 25392 25393 * NXP LPC17xx/40xx Drivers: 25394 25395 - LPC17xx/40xx CAN: If BOARD_CCLKSEL_DIVIDER is not equal to 1 on 25396 LPC178x or LPC40xx then base clock rate is calculated incorrectly 25397 because CCLK frequency does not correspond to PLL0 clock which is 25398 used for PCLK. This is partially workaround solution. It would 25399 be probably better to define BOARD_PCLK_FREQUENCY even for LPC176x 25400 targets and use that to replace divisor by base_clock in up_dev_s. 25401 From Pavel Pisa. 25402 25403 * NXP LPC17xx/40xx Boards: 25404 25405 - LPC17xx/40xx Ethernet: Add missing LPC17_40_PHY_CEMENT_DISABLE 25406 variable to the lpc17xx/40xx Kconfig file. For some reason this 25407 setting was not referenced anywhere except in the Ethernet driver. 25408 From Augusto Fraga Giachero. 25409 - LPC17xx/40xx Ethernet: Fix the initialization for DP83848x PHYs. 25410 The DP83848x requires the RMII mode to be manually enabled through 25411 the MII_DP83848C_RBR register. Before querying the speed and mode 25412 it should wait for the link to be established. From Augusto Fraga 25413 Giachero. 25414 25415 * NXP i.MXRT Drivers: 25416 25417 - i.MXRT LPUART: Fix some errors in the LPUART register definition 25418 files. Correct naming of a function: up_earlyserialinit() should 25419 be imxrt_earlyserialinit(). Remove prototypes for non-existent 25420 serial initialization functions. From Gregory Nutt. 25421 - i.MXRT USDHC: uSDHC typo fixes and command transfer error handling 25422 modified. From Ivan Ucherdzhiev. 25423 25424 * SiLabs EFM32 Drivers: 25425 25426 - EFM32 OTG host: Adam Porter's various fixex for STM32 FS/HS 25427 probably should be applied to EFM32 host which which has very 25428 similar IP. From Gregory Nutt. 25429 25430 * STMicro STM32: 25431 25432 - STM327F Configuration: Kconfig add depends on BBSRAM. From David 25433 Sidrane. 25434 - STM32F7 Interrupts: Fix overwritten IRQ enable. System boot order 25435 calls clock_initialize() then up_initialize(). clock_initialize() 25436 was setting up the alarm IRQ up_initialize is initializing the NVIC. 25437 This most likely worked in the past due to a bug in the NVIC 25438 initialization code that failed to clear the Interrupt enables. 25439 - STM32H7: Rix BBSRAM name in memory map. From David Sidrane. 25440 - STM32H7: Removed f7 in file path. From David Sidrane. 25441 25442 * STMicro STM32 Drivers: 25443 25444 - STM32H7 BBSRAM: Fix issues causing no writes and hardfaults. From 25445 David Sidrane. 25446 - STM32H7 BBSRAM: Convince compiler to perform 32 bit write. From 25447 David Sidrane. 25448 - STM32F7 OTGHS: Fixes bad preprocessor logic preventing USB OTG HS 25449 to work when used without external ULPI. From Anthony Merlino. 25450 - STM32 OTGH[FS|HS] Host STM32 host only initiates transfer if 25451 buflenl > 0. From Adam Porter. 25452 - STM32F7/H7/L4 OTG host: Adam Porter's fix for STM32 FS/HS probably 25453 should be applied to STM32 F7, H7, and L4 OTG host which are very 25454 similar. From Gregory Nutt. 25455 - STM32/F7/H7/L4: This change was required to get my devices 25456 (CDC-MBIM) to enumerate. Initially the system timed out retrieving 25457 the USB configuration descriptor. Ctrl IN requests got nothing but 25458 NAKs. I found that the initial SETUP packet and corresponding IN 25459 transfer were fine; it was the Status OUT phase that was getting the 25460 NAK. After receiving a NAK on the Status OUT, the code would loop 25461 back and issue another ctrl IN, which will always fail because the 25462 data was already transferred before. Thus the entire transfer would 25463 'timeout'. The fix I implemented moves the DATANAK timeout loop to 25464 only apply to the Status OUT. Both the ctrl IN and the Status OUT 25465 need their own retry loops. From Adam Porter. 25466 - STM32F7 SDMMC: If there is only one SDMMC it is slot 0 From David 25467 Sidrane. 25468 - STM32F7 USART1: USART1_RXDMA is dependent on STM32F7_DMA2 not 25469 STM32F7_DMA1 From Anthony Merlino. 25470 - STM32H7 DBGMCU: Memory Map DBGMCU is @ 0x5c001000 From David 25471 Sidrane. 25472 - STM32F7 SDMMC: Fix warning when DMA is not enabled. From David 25473 Sidrane. 25474 - STM32H7 Ethernet: Fix some errors in Ethernet MAC configuration. 25475 From Markus Bernet. 25476 - STM32H7 Ethernet: Correct stm32h7 mac address filtering. Correct 25477 the MAC address 0 register definition and remove the 'receive all' 25478 flag. Now the Ethernet driver only receives packets addressed to 25479 correct MAC. From Jukka Laitinen. 25480 - STM32H7 Ethernet: Correct memory corruption error. The Ethernet 25481 driver initialization incorrectly wrote to DMACRXCR instead of 25482 DMACSR when trying to clear the stopped flags. This caused 25483 invalid buffer length in the DMACRXCR, causing DMA to overflow the 25484 RX buffers when large packets are sent to the device. From Jukka 25485 Laitinen. 25486 - STM32H7 PWR: Ensure data is flushed on backup domain access 25487 changes. From David Sidrane. 25488 - STM32H7 Serial: Serial fix undefined with TERMIOS From David 25489 Sidrane. 25490 - STM32H7 UARTs: Fix UART7/8 typos. Fix bug in ETH_MACQTXFCR 25491 configuration. From Markus Bernet. 25492 25493 * STMicro STM32 Boards: 25494 25495 - Multiple STM32 Boards: If CONFIG_SCHED_CRITMONITOR is selected, 25496 then make sure that ITM and DWT resources are enabled before 25497 accessing ITM and DWT registers. By default, these registers are 25498 disabled. Suggested by Juha Niskanen. From Gregory Nutt. 25499 - Nucleo-H743ZI: Correct logic that determines if the RTC driver is 25500 available. Find in build testing. From Gregory Nutt. 25501 - Nucleo-G071RB: Fix linker script to avoid .ARM.exidx section 25502 overlap with .data From Daniel Pereira Volpato. 25503 - Modify all linker scripts (all boards, all architectures) to use 25504 solution from Daniel P. Volpato. From Alan Carvalho de Assis. 25505 - Nucleo-L432KC ADC: Change analog pins definitions and correct DMA 25506 related issue. From Daniel P. Carvalho. 25507 25508 * TI Tiva: 25509 25510 - Tiva Configuration: Rename TM4C123GH6PMI identifiers to 25511 TM4C123GH6PM. Rationale: In terms of firmware programming, there 25512 is no functional difference between these parts: TM4C123GH6PMI7, 25513 TM4C123GH6PMI7R, TM4C123GH6PMT7, and TM4C123GH6PMT7R. From a 25514 programming standpoint, all of the above parts are TM4C123GH6PM, 25515 which means it doesn't make sense to differentiate between PM and 25516 PMI. (The PM means 64-LQFP. The I means temperature range -40C to 25517 +85C. It could be T meaning -40C to +105C. The R means it ships in 25518 Tape and Reel packaging as opposed to Tray.) From Nathan Hartman. 25519 - Tiva Configuration: Rename TM4C1294NC identifiers to TM4C1294NCPDT. 25520 Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP, 25521 TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently 25522 supported by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL 25523 "Connected LaunchPad" (see configs/tm4c1294-launchpad). To ensure 25524 the correct part is fully specified, this commit updates all 25525 TM4C1294NC identifiers to TM4C1294NCPDT. From Nathan Hartman. 25526 - Tiva Configuration: Fix TM4C129XNCZAD part number in Kconfig and 25527 identifiers. Rationale: Fully specify that this is the 212-pin BGA 25528 package (ZAD ending) and for consistency with earlier changes to 25529 other Tiva TM4C12x part numbers in Kconfig names and identifiers. 25530 From Nathan Hartman. 25531 25532 * TI Tiva Drivers: 25533 25534 - Tiva TM4C 1-Wire: Fix wrong description on define TIVA_1WIRE_BASE: 25535 Was "EEPROM and Key Locker" (same as the item above). Now "1-Wire 25536 Master Module." Make DMACTL symbols visible for TM4C123: Remove 25537 "#ifdef CONFIG_ARCH_CHIP_TM4C129" guard around UART DMA Control 25538 (DMACTL) symbols. These bits are valid on TM4C123 devices, as well 25539 as on TM4C129. Also, improve the comment on UART_DMACTL_DMAERR. 25540 From Nathan Hartman. 25541 - Tiva GPIO Interrupts: LM3S, LM4F, TM4C: Fix GPIO IRQ error, ports 25542 R, S, T. Preprocessor logic for CONFIG_TIVA_GPIOx_IRQS was setting/ 25543 clearing port Q defines when it should act on ports R, S, T. 25544 gpioport2irq() was missing handling for port T. From Nathan 25545 Hartman. 25546 - Tiva Timers: Fix minor errors in tiva_timerlib.c. Fix incorrect 25547 preprocessor conditionals related to Kconfig defines: 25548 CONFIG_TIVA_TIMER32_EDGECOUNT -> CONFIG_TIVA_TIMER16_EDGECOUNT, 25549 CONFIG_TIVA_TIMER32_TIMECAP -> CONFIG_TIVA_TIMER16_TIMECAP, 25550 CONFIG_TIVA_TIMER32_PWM -> CONFIG_TIVA_TIMER16_PWM. From Nathan 25551 Hartman. 25552 - Tiva Timers: Fix errors in low-level timer support. 25553 tiva_gptm_configure() and tiva_gptm_release() were calling 25554 tiva_emac_periphrdy() instead of tiva_gptm_periphrdy(). Fix 25555 error in "abcde" description of bit flag defines. From Nathan 25556 Hartman. 25557 - Tiva Timers: Fix one code error and some comment errors. 25558 tiva_timer16_setinterval(): Was DEBUGASSERTing on mode != 25559 TIMER16_MODE. Fixed to DEBUGASSERT on mode == TIMER16_MODE. 25560 From Nathan Hartman. 25561 25562 * ZiLOG Z80 Boards: 25563 25564 - z80sim Serial: Fix uart_dev_t initializer: pollfds[] is a array of 25565 pointers and, hence, the NULL initializer must be included in braces. 25566 Noted by Paul Osmialowski in Issue #160. From Gregory Nutt. 25567 - z80sim Interrupts: Missed a name change up_irqinitialize to 25568 z80_irq_initialize. From Gregory Nutt. 25569 25570 * C Library/Header Files: 25571 25572 - include/netinet/in.h: Rename __pad member to sin_zero in struct 25573 sockaddr_in. Libwebsockets initializes the 'sin_zero' member of 25574 sockaddr_in objects to zeros. Apparently, judging from mailing list 25575 entries, there are platforms on which not doing this causes 25576 undefined behavior. On NuttX compiling respective code is broken, 25577 as the corresponding member variable is called '__pad'. Neither in 25578 the 'nuttx' nor in the 'apps' repository did I find any reference to 25579 this identifier. Thus, I believe its a safe bet to just rename it. 25580 UNIX Network Programming states in this regard: "The POSIX 25581 specification requires only three members in the structure: 25582 sin_family, sin_addr, and sin_port. It is acceptable for a POSIX- 25583 compliant implementation to define additional structure members, and 25584 this is normal for an Internet socket address structure. Almost all 25585 implementations add the sin_zero member so that all socket address 25586 structures are at least 16 bytes in size." From Michael Jung. 25587 25588 - libs/libc/libc.csv: Correct dependency of setlocale on 25589 CONFIG_LIBC_LOCALE. From Pavel Pisa. 25590 - libs/libc/machine/arm/armv7-m: Fix build error for ELF. From 25591 Masayuki Ishikawa. 25592 - libs/libc/math.csv: Correct format of some function entries. From 25593 Pavel Pisa. 25594 25595 * Tools: 25596 25597 - tools/: Change all occurrences of /bin/(ba)sh in shell scripts to 25598 /usr/bin/env bash which appears more portable From Manuel St�hn. 25599 25600 * NSH Library: apps/nshlib: 25601 25602 - apps/nshlib/: As noted by David S. Alessio, 'cat' should not output 25603 any additional newline at the end of the cat'ed file content. This 25604 additional newline was added to assure that the NSH prompt was 25605 presented on a new line. However, that is not the correct behavior 25606 of 'cat' per the IEEE std: "The standard output shall contain the 25607 sequence of bytes read from the input files. Nothing else shall be 25608 written to the standard output." Reference: 25609 https://pubs.opengroup.org/onlinepubs/009695399/utilities/cat.html. 25610 This commit changes the function nsh_catfile() which underlies the 25611 'cat' command and well as other NSH commands. Although this is the 25612 correct behavior for 'cat' it may not be the correct behavior for 25613 other commands implemented via nsh_catfile(). That remains to be 25614 determined. From Gregory Nutt. 25615 25616 * System Utilities: apps/system: 25617 25618 - apps/system/cle/: ASCII DEL should be treated by Delete-Left. From 25619 Dave Marples. 25620 - apps/system/i2ctool: (1) Friendlier I2C "knock-knock" uses only 25621 read request. While many I2C slave devices have multiple indexed 25622 registers, some have only one register and it's not indexed. For 25623 example, the I2C bus switch TCA9548A has only a Control Register, 25624 attempting to index to "Reg[0]" alters its contents to 0x00 25625 disabling all subordinate buses. This patch fixes that problem by 25626 simply trying to read something/anything from the slave. This also 25627 helps coax out slaves with register files that start from a higher 25628 index, i.e. the AT24CS0x, FLASH chips with a UUID that appears as a 25629 2nd I2C slave at (address+8), report their serial number at 25630 Reg[80]-Reg[8F] and will NAK a read of Reg[0]. (2) Modify get/set 25631 to prevent write of reg index if not specifed From David Alessio. 25632 25633 * Network Utilities: apps/netutils: 25634 25635 - apps/netutils/dhcpd: Fixes bug where hwaddr was being used instead 25636 of ipaddr in the ARP update. This bug seems to have been introduced 25637 three years ago during a rewrite to remove a direct OS call to arp. 25638 I'm not sure how others have not run into issues with this. The 25639 behavior I was observing was that the DHCPD would go to offer an IP 25640 address, but then send a ARP request for the IP instead because it 25641 didn't know where to send the data. From Anthony Merlino. 25642 - apps/netutils/netinit/: Remove warnings. Unhook PHY notification 25643 signal handler when cleaning up, if an error occurs after the signal 25644 handler is put into place. From Nathan Hartman. 25645 25646 * Wireless Utilities: apps/wireless: 25647 25648 - apps/wireless/ieee802154/i8sak: Fixes conversion from extended 25649 address to IPv6 address. From Anthony Merlino. 25650 25651NuttX-8.2 Release Notes 25652------------------------ 25653 25654The 133nd release of NuttX, Version 8.3, was made on November 16, 2019, 25655and is available for download from the Bitbucket.org website. Note 25656that release consists of two tarballs: nuttx-8.2.tar.gz and 25657apps-8.2.tar.gz. These are available from: 25658 25659 https://bitbucket.org/nuttx/nuttx/downloads 25660 https://bitbucket.org/nuttx/apps/downloads 25661 25662Both may be needed (see the top-level nuttx/README.txt file for build 25663information). 25664 25665Additional new features and extended functionality: 25666--------------------------------------------------- 25667 25668 * Core OS: 25669 25670 - Signals: Add support for SIGPIPE default action. SIGPIPE uses 25671 SIG_SIGPIPE_ACTION which terminates process by default. It also 25672 could be ignored. From liuhaitao. 25673 - Spinlocks: Remove support for re-entrant spinlocks. They seemed 25674 like a good idea, but they are never used. From Xiang Xiao. 25675 - Memory Manager: Remove the assumption that one character equals 25676 eight bits. From Xiang Xiao. 25677 - Power Management: Historically, the NuttX PM subsystem has 25678 consisted of two functional components: (1) an "Upper" part that 25679 detects state changes based on a random walk driven by activity 25680 levels, and (2) and "lower" part that implementst the state changes. 25681 This change decouples that upper activity-based logic from the lower 25682 random walk logic and allows use of other upper state detection 25683 logic (such as a custom, application-specific state machine). From 25684 Matias Nitsche. 25685 - boardctl(): Expose power manager function through boardctl() 25686 interface. From Xiang Xiao. 25687 25688 * File System/Block and MTD Drivers: 25689 25690 - GD25: Add support for a new FLASH vendor. From zhangbo_a. 25691 - GD25: Add support for GD25 device with 256-Mbit capacity. From 25692 YanLin Zhu. 25693 - GD25: Add 4-byte address operation for capacity larger than 25694 128-Mbit. From YanLin Zhu. 25695 - GD25: Add gd25_lock/unlock to case: enable 4-bytes address From 25696 ligd. 25697 - GD5F: Add gigadevice SPI NAND FLASH driver. From YanLin Zhu. 25698 25699 * Networking/Network Drivers: 25700 25701 - Networking: Use ntoh() when printing IPv6 addresses so that the 25702 addresses appear in friendlier host order vs. network order. From 25703 Bernd Walter. 25704 - Netlink: Implement minimal NETLINK_ROUTE socket functionality that 25705 can (for now) be use used to obtain a list of network devices, IPv4 25706 ARP and IPv6 Neighbor tables, and IPv4 and IPv6 routing tables. 25707 From Gregory Nutt. 25708 25709 * Wireless/Wireless Drivers: 25710 25711 - BCM43438A1 Bluetooth: Add support for the BCM43438A1 Bluetooth 25712 capability. From Dave Marples. 25713 - HCIUART Shim: Add a serial 'shim' to allow any regular serial port 25714 to support a Bluetooth H4 interface and to be used to drive a 25715 Bluetooth device. From Dave Marples. 25716 - BCM4343x HCIUART: BCM4343x HCIUART support. From Dave Marples. 25717 - BCM43xxx: Move drivers/wireless/ieee80211/ to 25718 drivers/wireless/ieee80211/bcm43xxx/ since the directory only 25719 contains only BCM43362 and BCM43438 related code. From Xiang Xiao. 25720 - GS2200M: Add reset handler to interface. Add reset and un-reset 25721 sequence in driver. From Masayuki Ishikawa. 25722 25723 * Audio/Audio Drivers: 25724 25725 - Audio: Add message type to support audio trigger. From anchao. 25726 25727 * Other Common Device Drivers: 25728 25729 - Altair: Add support for the altair LTE modem driver. From Alin 25730 Jerpelea. 25731 - MCP2515: MCP2525 SPI STD-EXT ID fixes. From DisruptiveNL. 25732 - OpenAMP: Brings in the drivers needed to support OpenAMP. These 25733 changes were ported from https://github.com/FishsemiCode/nuttx. 25734 This port was effort of a number of people, I rather arbitrarily 25735 gave authorship to Guiding Li because he has the largest number of 25736 fundamental quashed commits from the Xiamoi repository. From 25737 Guiding Li. 25738 25739 * Simulator: 25740 25741 - Simulator: Add stack coloration feature. From ligd. 25742 - Simulator: Report PM activity on simulated UART. From Matias 25743 Nitsche. 25744 - Simulator: Add host ftruncate() support. From chao.an. 25745 - Simulator: Replace all CONFIG_DEV_CONSOLE with USE_DEVCONSOLE for 25746 arch/sim and compile up_devconsole.c conditionally. From Xiang 25747 Xiao. 25748 - Simulator OpenAMP: Support OpenAMP between two simulator 25749 instances. Please read rpserver/rpproxy section in 25750 boards/sim/sim/sim/README.txt for more information. From chao.an. 25751 25752 * ARMv7-M 25753 25754 - ARMv7-M: Add BPIALL register address. From Dave Marples. 25755 - ARMv7-M MPU: Add user peripheral helper 25756 25757 * Atmel SAMD2/L2 Boards: 25758 25759 - Arduino-M0: Add initial board support for the Arduino M0 which is 25760 based on the SAMD21 chip. Include nsh and usbnsh configurations. 25761 From Alan Carvalho de Assis. 25762 25763 * NXP i.MXRT Drivers: 25764 25765 - i.MXRT LCD: Add support for LCD. Clean up some LCD-related 25766 interfaces. From Fabio Balzano. 25767 - i.MXRT Serial: This change improves the performance of UART serial 25768 ports on the IMXRT by enabling the RX & TX FIFOS and transmission on 25769 the holding register being empty (TDRE) rather than transmission 25770 being complete (TC). From Dave Marples. 25771 - i.MXRT Pin Mux: This change separates out the pinmux and iomux 25772 functions cleanly. For ease of conversion default IOMUX definitions 25773 have been added into imxrt_iomux.h. The change effectively does two 25774 things: (1) unifies the iomux definitions - previously some pins 25775 had them, and some didn't. This effectively made it impossible to 25776 use the pinmuxes without editing the header file in the standard 25777 distribution tree. And (2) unifies the pin definitions so that every 25778 pin now has a suffix. This makes it *much* easier to see when a pin 25779 is in use in your code, because it will always have a definition in 25780 your board.h file. From Dave Marples. 25781 - IMXRT1020-EVK: Add support for the MIMXRT1021-EVK board. It 25782 features nsh, netnsh and usdhc sample configurations. From Dave 25783 Marples. 25784 25785 * NXP i.MXRT Boards: 25786 25787 - IMXRT1060-EVK: Add basic LCD support for the board IMXRT1060-EVK. 25788 From Fabio Balzano. 25789 - IMXRT1060-EVK: Added Littlevgl demo configuration into the 25790 IMXRT1060-EVK board directory. From Fabio Balzano. 25791 25792 * NXP/Freescale Kinetis Drivers: 25793 25794 - Kinetis Ethernet: Add support for TJA1100 PHY. From David Sidrane. 25795 25796 * NXP S31K1xx: 25797 25798 - S32K1xx: Support configuration and initialization of the flash 25799 configuration bytes. From Gregory 25800 25801 * NXP S31K1xx Boards: 25802 25803 - S32K1**EVB: Create a special FLASH section to hold the FLASH 25804 configuration bytes. From Gregory Nutt. 25805 - S32K146EVB: Added configuration script and instructions for using 25806 Thread-Aware OpenOCD for the S32K146 with Eclipse. From Han 25807 Raaijmakers. 25808 25809 * Renesas RX65N: 25810 25811 - RX65N: Adds a port of to the Renesas RX65N Micro-controller. This 25812 port includes Serial (UART) driver (13 ports) and Ethernet 25813 driver. From Anjana. 25814 25815 * Renesas RX65N Boards: 25816 25817 - RSK RX65N-2MB: Add support for the RSK RX65N-2MB board. From 25818 Anjana. 25819 - GR-Rose: Add support for the GR-Rose board. From Anjana. 25820 25821 * Sony CXD56xx 25822 25823 - CXD56xx CPU FIFO: Add configurations for CPU FIFO elements. From 25824 Alin Jerpelea. 25825 - CXD56xx Loader: Update loader and gnssfw ver. 17660. From Alin 25826 Jerpelea. 25827 - CXD56xx SMP: Add support for SMP. To run cxd56xx in SMP mode, new 25828 boot loader which will be released later must be used. From 25829 Masayuki Ishikawa. 25830 - CXD56xx SMP: Add IRQ routing for SMP in cxd56_irq.c. In CXD56xx, 25831 each external interrupt controller can be accessed from a local 25832 APP_DSP (Cortex-M4F) only. This change supports IRQ routing for SMP 25833 by calling up_send_irqreq() in both up_enable_irq() and 25834 up_disable_irq(). From Masayuki Ishikawa. 25835 25836 * Sony CXD56xx Drivers: 25837 25838 - CXD56xx I2C: Add ability to set the i2c frequency to other than just 25839 100 or 400 Hz. From Alin Jerpelea. 25840 - CXD56xx SDHCI: Reduce power consumption by stopping SD clock. Re- 25841 enable SD clock during access to SD card. Improve GNSS low 25842 sensitivity with SD card inserted. From Alin Jerpelea. 25843 25844 * Sony CXD56xx Spresense Board: 25845 25846 - CXD56xx Board Common: Add the Altair LTE modem support on the 25847 Spresense board. From Alin Jerpelea. 25848 - CXD56xx Board Common: Add Spresense Image Processor. Enable support 25849 for accelerated format converter, rotation and so on. using the CXD5602 25850 image processing accelerator. 25851 - Spresense: Add board specific pin configurations of CXD5602 pins to 25852 fit Spresense board. From Takayoshi Koizumi. 25853 - Spresense: Add a configuration option to select if an extension 25854 board is attached to the SPresence. If there is no extension board 25855 attached, the SPresense may run in a low-power mode by default (as 25856 determined by the CONFIG_CXD56_CUSTOM_PINCONFIG option). If an 25857 extension board is present, then the SPresense will need to run at a 25858 higher power mode, selected by the new CONFIG_SPRESENSE_EXTENSION 25859 option. From Gregory Nutt. 25860 - Spresense Camera: Add ISX012 camera initialization and 25861 configuration. From Alin Jerpelea. 25862 - Spresense OS test: Enable ostest in rndis/defconfig and 25863 wifi/defconfig. From Masayuki Ishikawa. 25864 - Spresense: Add --gc-sections to LDFLAGS and add -ffunction-sections 25865 and -fdata-sections to ARCHCFLAGS in scripts/Make.defs. From 25866 Masayuki Ishikawa. 25867 - Spresense SMP: Add smp configuration. From Masayuki Ishikawa. 25868 - Spresense SCU: The SCU has to be initialized at bootup on Spresense 25869 board because several functions depend on it. Add audio control 25870 definitions. Add configuration for the audio implementation. From 25871 Alin Jerpelea. 25872 - Spresense: Add audio and board audio control implementation. From 25873 Alin Jerpelea. 25874 - Spresense: Sdd power_control and audio_tone_generator. Add a simple 25875 way to control the audio buzzer with defined frequency for user-space 25876 apps. From Alin Jerpelea. 25877 - Spresense: Add the optional initialization of GNSS and GEOFENCE at 25878 boot if the drivers are enabled From Alin Jerpelea. 25879 - Spresense: Add LTE configuration. From Alin Jerpelea. 25880 - Spresense: Enable high current mode for the Spresense Extension 25881 board on all examples that have SDCARD support. From Alin Jerpelea. 25882 - Spresense: Add lcd examples configuration. This is a configuration 25883 for the basic nx examples From Alin Jerpelea. 25884 25885 * STMicro STM32: 25886 25887 - STM32F0/L0/G0: Add support for STM32G070xx family. From Daniel 25888 Pereira Volpato. 25889 - STM32F0/L0/G0 Power: Scale dynamic voltage and flash wait states 25890 properly on STM32G0 chips.

From Jussi Kivilinna. 25898 - STM32 L4 LPTIM: Add support for LPTIM timers on the STM32L4 as PWM 25899 outputs. From Matias N. 25900 - STM32 H7 Progmem: Add FLASH progmem support. From David Sidrane. 25901 25902 * STMicro STM32 Drivers: 25903 25904 - STM32 Serial: Single Wire add pull{up|down|none} via new IOCTL 25905 command. From David Sidrane. 25906 - STM32 F0/L0/G0 Serial: Single Wire add pull{up|down|none} via 25907 new IOCTL command. From David Sidrane. 25908 - STM32 F0/L0/G0 PWM: Add PWM support. From Daniel Pereira Volpato. 25909 - STM32 G0 TIM: Support timers available on STM32G070. Includes TIM1 25910 PIOs, TIM driver lower-half. From Daniel Pereira Volpato. 25911 - STM32 F7 Serial: Single Wire add pull{up|down|none} via new IOCTL 25912 command. From David Sidrane. 25913 - STM32 H7 BBSRAM: Exclude BBSRAM from cacheable when 25914 CONFIG_ARMV7M_DCACHE. ST placed the STM32H7 BBSRAM in the SRAM 25915 default memory region which is cacheable. This change sets the 25916 BBSRAM memory range to non-cacheable. From David Sidrane. 25917 - STM32 H7 SDMMC: Add SDMMC support and IDMA as well as interrupt 25918 driven transmission. Support pull-ups and SDIO. From David Sidrane. 25919 - STM32 H7 Serial: Single Wire add pull{up|down|none} via new IOCTL 25920 command. From David Sidrane. 25921 - STM32 L4 OTGFS: Enable OTGFS for STM32L4+ series. The OTGFS 25922 peripheral on stm32l4x6 and stm32l4rxxx reference manual is exactly 25923 the same. From Jussi Kivilinna. 25924 - STM32L4 IDLE Loop: (1) Added BEGIN_IDLE()/END_IDLE() to stop call 25925 so that we also get notification via LED of the STOP mode, (2) Added 25926 the stm32l4_clockenable call as previously discussed, and (3) Added 25927 call to pm_changestate() to inform drivers we're back to running 25928 after the call to stm32l4_stop() returns. From Matias N. 25929 - STM32 L4 Serial: Single Wire add pull{up|down|none} via new IOCTL 25930 command. From David Sidrane. 25931 25932 * STMicro STM32 Boards: 25933 25934 - Nucleo-G070RB: Initial support for board STM32 NUCLEO-G070RB, 25935 including NSH config. Enables PWR peripheral and set SYSCLK to 25936 maximum frequency. From Daniel Pereira Volpato. 25937 - Nucleo-G070RB: Enable basic timers. Add TIMx clock frequencies to 25938 board.h.

From David Alessio. 25951 - STM32F4-Discovery: Add support for external DS1307 module. From 25952 Alan Carvalho de Assis. 25953 - STM32F4-Discovery: Add support for MMCSD_SPI. This change works 25954 with STM32F4 Discovery Shield plus microSD click From Masayuki 25955 Ishikawa. 25956 - STM32F4-Discovery: Add support for gs2200m. Works with mikroe 25957 STM32F4 Discovery Shield (slot3) From Masayuki Ishikawa. 25958 25959 * TI Tiva: 25960 25961 - TM4C129ENCPDT: Add support for Tiva TM4C129ENCPDT. From Nathan 25962 Hartman. 25963 25964 * TI Tiva Boards: 25965 25966 - TM4C123G-Launchpad: SPI CAN functionality on TM4C123GXL. From 25967 DisruptiveNL. 25968 25969 * Build System: 25970 25971 - tools/Config.mk: Eliminate use of the built-in implicit rules. 25972 From anchao. 25973 - tools/Config.mk and Makefile.unix: Support the incremental build 25974 for configuration change. From Xiang Xiao. 25975 - tools/Config.mk: Support the ability to change the CFLAGS for 25976 the compilation of a single file. Set special compiler options as 25977 follows the rule: sourcefile + fixed suffix "_[A|C|CPP|CXX]FLAGS". 25978 For example in apps/examples/hello/Makefile: 25979 $(SRCDIR)/hello_main.c_CFLAGS = -DTEST. From Xiang Xiao. 25980 - Configuration: Auto-select CONFIG_BUILD_LOADABLE when either 25981 CONFIG_BUILD_KERNEL or CONFIG_BINFMT_LOADABLE is selected. From 25982 Xiang Xiao. 25983 25984 * Libraries/Header Files: 25985 25986 - libs/libc: Add CONFIG_MODLIB_SYSTEM_SYMTAB to generate the symbol 25987 table for dlopen/insmod. From Xiang Xiao. 25988 - getdelim() and getline(): Add implementations of the POSIX 25989 functions getdelim() and getline(). Because of how the function is 25990 defined, getline() canot be used on platforms that use CR-LF lin 25991 terminations. From Gregory Nutt. 25992 - alarm(), setitimer(), and getitimer(): Implement alarm(), 25993 setitimer() and getitimer() APIs. From liuhaitao. 25994 25995 * Tools: 25996 25997 - tools/mkexport.sh: Copy the essential build script files too and 25998 move Make.defs/gnu-elf.ld into scripts like board folder layout. 25999 From Xiang Xiao. 26000 - tools/mkexport.sh: Should export full content for FLAT build even 26001 with CONFIG_BUILD_LOADABLE. From Xiang Xiao. 26002 - tools/testbuild.sh: Add an option to select the number of CPUs to 26003 use with 'make' From Gregory Nutt. 26004 - tools/indent.sh: Add a command line option to suppress reformatting 26005 of comments. This is useful when comments are already correct 26006 and/or contain formatted data such as tables or lists. From Gregory 26007 Nutt. 26008 - tools/nxstyle.c: Add detection of carriage returns. Improve 26009 reporting of TABs. From Gregory Nutt. 26010 - tools/nxstyle.c: Add logic to detect if there is a blank line 26011 following the final right brace. From Gregory Nutt. 26012 - tools/nxstyle.c: Eliminate false alarm errors on comments that are 26013 to the right of code when the comment terminator is on the same 26014 line as the last of the comment. From Gregory Nutt. 26015 - tools/nxstyle.c: Eliminate false alarms when checking for 26016 alignment of comments to the right of code. Fix check for C++ style 26017 comments so that strings like http:// and https:// do not generate 26018 false alarms. From Gregory Nutt. 26019 - tools/nxstyle.c: Eliminate false positive 'Invalid character after 26020 asterisk in comment block'. From Gregory Nutt. 26021 26022 * apps/ Build System: 26023 26024 - apps/ Build System: Numerous changes for improvements and general 26025 clean-up of the apps/ build system. Too many small and individual 26026 changes to list here. Includes many improvements related to loadable 26027 modules and symbol table generation, removal of duplicated logic, 26028 renaming of binary directories, use of cygpath, etc. From Xiang Xiao. 26029 - apps/Application.mk: Support the ability to change the CFLAGS for 26030 the compilation of a single file. Set special compiler options as 26031 follows the rule: sourcefile + fixed suffix "_[A|C|CPP|CXX]FLAGS" 26032 As an example in apps/examples/hello/Makefile: 26033 $(SRCDIR)/hello_main.c_CFLAGS = -DTEST 26034 From Xiang Xiao. 26035 - apps/Application.mk and main.c files: Change builtin's entry point 26036 from main to xxx_main by macro expansion. This change make the 26037 entry point fully compliant with POSIX/ANSI standard. From Xiang 26038 Xiao. 26039 26040 * Examples/Tests: apps/examples: 26041 26042 - apps/examples/audio_rttl: Add a simple RTTL player demo that is 26043 able to play tunes according to an RTTL song. From Alin Jerpelea. 26044 - apps/examples/bmi160: Add bmi160 example app. This app will read 26045 the BM160 data and list it on the NSH console. From Alin Jerpelea. 26046 - apps/examples/charger: Simple charger example that will display on 26047 the console voltage and current values. From Alin Jerpelea. 26048 - apps/examples/netlink_route: Add test/example of NETLINK_ROUTE 26049 'get' operations. From Gregory Nutt. 26050 26051 * NuttShell: apps/nshlib: 26052 26053 - apps/nshlib/: Add rptun cmd for boot remote core. From ligd. 26054 - apps.nshlib/: Add a -t option to the arp command which will enable 26055 printing the entire ARP table. From Gregory Nutt. 26056 - apps/nshlib/: Add new NSH command, 'pmconfig'. From ligd. 26057 26058 * System Utilities: apps/system: 26059 26060 - apps/system/cle: Add basic color support to the CLE editor. 26061 From Dave Marples. 26062 - apps/system/i2c: While many I2C slave devices have multiple 26063 indexed registers, some have only one register and it's not indexed. 26064 For example, the I2C bus switch TCA9548A has only a Control 26065 Register, attempting to index to "Reg[0]" alters its contents to 26066 0x00 disabling all subordinate buses. This change fixes that 26067 problem by simply trying to read something/anything from the slave. 26068 This also helps coax out slaves with register files that start from 26069 a higher index, i.e. the AT24CS0x, FLASH chips with a UUID that 26070 appears as a 2nd I2C slave at (address+8), report their serial 26071 number at Reg[80]-Reg[8F] and will NAK a read of Reg[0]. Modified 26072 get/set to prevent write of reg index if not specified. 26073 - apps/system/i2c: Added a 'dump' command to issue a single 26074 transaction to retrieve multiple bytes from an I2C slave and 26075 register/offset. From David Alessio. 26076 - apps/system/spi: Add options to specify devtype, id for chip 26077 select. From David S. Alessio. 26078 - apps/system/symtab: Remove system/symtab since the same 26079 functionality exist in nuttx now. From Gregory Nutt. 26080 - apps/system/usrsock_rpmsg: Add rpmsg based usrsock implementation. 26081 From Jianli Dong. 26082 26083 * Network Utilities: apps/netutils: 26084 26085 - apps/netutils/cjson/: Update default version to 1.7.12. Previous 26086 releases raise compilation warnings about redefined true/false. 26087 From raiden00pl. 26088 - apps/netutils/netlib/: Add a function to read the entire ARP table 26089 using NETLINK_ROUTE protocol. From Gregory Nutt. 26090 - apps/netutils/netlib/: Add support for retrieving a snapshot of the 26091 IPv6 neighbor table using Netlink sockets. From Gregory Nutt. 26092 - apps/netutils/netlib/: Add a utility function that will return a 26093 list of all network devices in the UP state. From Gregory Nutt. 26094 - apps/netutils/netlib/: Add function to retrieve routing tables 26095 using Netlink. From Gregory Nutt. 26096 26097Bugfixes: 26098--------- 26099Only the most critical bugfixes are listed here (see the ChangeLog for a 26100more complete list of bugfixes and for additional, more detailed bugfix 26101information): 26102 26103 * Core OS: 26104 26105 - Signals: Fix undefined reference from sig_default.c to 26106 sched_suspend() if CONFIG_SIG_SIGSTOP_ACTION is not defined. From 26107 raiden00pl. 26108 - waitpid(): Fix a NULL pointer dereference on race without 26109 DEBUG_ASSERT. From David Alessio. 26110 - WD Timers: Back out a kludge-workaround in wd_start for an SDCC 26111 compiler problem fix back in Feb 2017. That workaround now appears 26112 to conflict with newer GCC versions using (unsupported) warning 26113 options and SDCC no longer needs the work-around. From Gregory 26114 Nutt. 26115 - clock_systimespec(): Fix early timespec overflow if using 32 bit 26116 system timer. From Jens Gr�f. 26117 - Spinlocks: spin_trylock handle memory barrier and instrumentation 26118 correctly. From Xiang Xiao. 26119 - Power Management: Fix a problem where a timer cannot start when it 26120 encounters a very small pmtick. From ligd. 26121 - boardctl(BOARDIOC_MKRD): This change corrects a problem with NSH: 26122 NSH was calling the OS internal function ramdisk_register() in 26123 violation of the portable POSIX interface. This change solves the 26124 problem by introducing a new boardctl() function BOARDIOC_MKRD 26125 which moves the RAM disk creation into the OS. From Gregory Nutt. 26126 - boardctl(BOARDIOC_ROMDISK): Add support for the new 26127 BOARDIOC_ROMDISK command. This allows applications to create ROMFS 26128 block drivers without illegal direct calls to romdisk_register. 26129 26130 * File System/Block and MTD Drivers: 26131 26132 - SmartFS: Fix O_CREAT without O_TRUNC truncating existing file. 26133 Also nothing in POSIX says that O_APPEND should prevent O_TRUNC. 26134 From Juha Niskanen. 26135 - SmartFS: Honor O_APPEND on writes. Also document pwrite() bug/ 26136 limitation. From Juha Niskanen. 26137 - GD25: spi_devid argument was not used in initialization. GD25 26138 driver was always using priv->spi_devid initialized to zero by 26139 kmm_zalloc(). This change initializes it from the supplied function 26140 argument. From Juha Niskanen. 26141 - MMC/SD: Set wrbusy after success of all the operations. Any 26142 failure could leave wrbusy set when it should not be if the 26143 operation failed. From David Sidrane. 26144 - MMC/SD: Enter a removed card state On a failure. If we fail to 26145 read cardstatus in mmcsd_transferready consider this a hard error 26146 and set the card to removed. From David Sidrane. 26147 - MMC/SD (SDIO): Align DMA buffer for MBURST size. From David S. 26148 Alessio. 26149 26150 * Networking/Network Drivers: 26151 26152 - Socket close(): Fixed problems noted by Bernd Walter: Eliminate an 26153 incomplete test when a disconnection event happens. When a 26154 disconnection event occurs, the close logic MUST always terminate 26155 the wait. The conditional test was not incorrect, however, it 26156 lacked 'else' logic and would simply ignore that disconnection event 26157 in some cases. That is bad because there may not be another 26158 disconnection event and that can lead to hangs (or at least very, 26159 very long delays). From Gregory Nutt. 26160 - ICMPv6: Dispatch ICMP_POLL to device's callback list too since 26161 icmpv6_neighbor stills append the callback into this list. From 26162 Gregory Nutt. 26163 - ICMPv6: Decouple autoconfig and ICMPv6 socket to avoid an invalid 26164 Kconfig combination. From Xiang Xiao. 26165 - ICMPv6: cmpv6_autoconfig() error handling must not overwrite 26166 overwrite the error code. From Xiang Xiao. 26167 - TCP/UDP: Fix a chicken and egg problem by eliminating the check of 26168 the arp/neighbor tables before packet transmission: 26169 1. For buffered TCP/UDP case, if CONFIG_NET_ARP_SEND / 26170 CONFIG_NET_ARP_IPIN / CONFIG_NET_ICMPv6_NEIGHBOR isn't enabled 26171 and the table doesn't contain the Ethernet address for the 26172 destination IP address yet, then the logic will skip the real 26173 transmission and then ARP/neighbor logic can't steal the final 26174 buffer to generate the ARP/ICMPV6 packet. 26175 2. For all other case, the TCP layer or user program should already 26176 contain the retransmit logic, the check is redundant and may 26177 generate many duplicated packets if ARP/ICMPV6 response is too 26178 slow because the cursor stop forward. If user is still concerned 26179 about the very first packet lost, he could fix the issue by 26180 enabling CONFIG_NET_ARP_SEND / CONFIG_NET_ICMPv6_NEIGHBOR. 26181 From Xiang Xiao. 26182 - UDP sendto(): Add a check for the device that is polling. In the 26183 multiple network device case, this check is necessary to prevent 26184 sending the UDP packet to the wrong device. From Gregory Nutt. 26185 26186 * Wireless/Wireless Drivers: 26187 26188 - MRF24J40: Correct erroneous isolation of address mode field and 26189 subsequent bad comparison. From Gregory Nutt. 26190 - GS2200M: Add SPI_SELECT() to _read/write_data() in gs2200m.c 26191 - BCM43xx Wireless: In the SDIO interface, the behavior of the DMA 26192 setup differs, depending on the hardware capability 26193 SDIO_CAPS_DMABEFOREWRITE. If this capability is set, then the DMA 26194 setup much be done before the transfer setup. Dave Marples 26195 modified this file for the i.MXRT USDHC which does have the 26196 SDIO_CAPS_DMABEFOREWRITE. Xiao Xiang reports that this change 26197 breaks the Wifi on the Photon which does not report the 26198 SDIO_CAPS_DMABEFOREWRITE and suggests reverting the change. In 26199 reality both changes are correct but must be conditioned on the 26200 DMA capability of the underlying SDIO device. From Gregory Nutt. 26201 26202 * Common Drivers: 26203 26204 - Various drivers (Cloned logic): On error, memory was freed, but 26205 the error was not returned. It just continued as though no error 26206 happened. From Petro Karashchenko. 26207 - Serial: Fix data corruption when outputting data in SMP mode From 26208 Masayuki Ishikawa. 26209 - Serial: serial_io.c used signal numbers, but did not include 26210 signal.h. This has no problems but missing signal definitions have 26211 been seen in certain cases. From David Sidrane. 26212 - Serial DMA: Avoid uart_xmitchars_done() move the tail bigger then 26213 head. If ioctl(TCOFLUSH) occurs between uart_xmitchars_dma() and 26214 uart_xmitchars_done(), TCOFLUSH will reset xmit buffer, then 26215 uart_xmitchars_done() will move the 'tail' ahead of 'head', then 26216 sends lots of wrong data. From ligd. 26217 - mkfifo(): mkfifo() should return -1 and set errno on failure From 26218 raiden00pl. 26219 - RAMLog: Fix ramlog readers never awakened up when using ramlog as 26220 syslog or console. We also make an attempt to avoid the thundering 26221 herd problem if there are multiple readers/pollers. This change also 26222 removes forcing CONFIG_RAMLOG_CRLF in nuttx/syslog/ramlog.h as there 26223 is no point of wasting precious RAM for useless characters. From 26224 Juha Niskanen. 26225 - USB CDC/ACM: Fix memory leak of RX failsafe timer. From Juha 26226 Niskanen. 26227 - USB HID Keyboard device: Fix keyboard debounce algorithm used when 26228 CONFIG_HIDKBD_NODEBOUNCE is undefined. From Jeff Theusch. 26229 - USB HID Keyboard: Change default for CONFIG_HIDKBD_POLLUSEC per 26230 recommendation of Jeff Theusch. From Gregory Nutt. 26231 - VL53L1X IOCTLs: IOCTL commands for the VL53L1X did not follow the 26232 sequence. Noted by Daniel Pereira de Carvalho. From Gregory Nutt. 26233 - syslog: syslog_force does not set errno so do not test against it. 26234 From Juha Niskanen. 26235 - syslog: Fix assertion that assumes re-opened syslog file is the 26236 same. Logic in syslog_file_channel() is calling syslog_initialize() 26237 for the default syslog device as a recovery action after failed 26238 syslog_dev_initialize(). From Juha Niskanen. 26239 26240 * Simulator: 26241 26242 - Simulator HostFS: Skip '.' and '..' in readdir' From Xiang Xiao. 26243 - Simulator HostFS: Fix warning: 'mapflags' may be used uninitialized 26244 in this function. From Xiang Xiao. 26245 - Simulator Tickless: Correct the calculation of the Tickless timer 26246 period. Fix some missing initialization of globals and missing 26247 return values. From Matias N. 26248 - Simulator: Add -m32 to HOSTLDFLAGS if enable CONFIG_SIM_M32. From 26249 Xiang Xiao. 26250 - Simulator PM: Fixes compilation for sim target when enabling power 26251 management. From Matias N. 26252 - Simulator Build: Fixes missing recursion into sim board directory 26253 for dependency generation. From Matias N. 26254 - Simulator SIMUART: Remove CONFIG_SIM_UART_DATAPOST for arch/sim. 26255 It's very dangerous to call NuttX API from simuart_thread. From 26256 Xiang Xiao. 26257 26258 * ARMv7-A 26259 26260 - ARMv7-A: Apply Masayuki Ishakawa's change for ARMv7-M to this SMP 26261 architecture as well. From Gregory Nutt. 26262 26263 * ARMv7-M 26264 26265 - ARMv7-M: Fix a deadlock in up_sigdeliver() in SMP mode. In 26266 previous implementation, up_disable_irq() was called before 26267 recovering local context. However, I noticed a deadlock happens in 26268 the following situation. For example, if up_sigdevliver() is in 26269 progress on CPU0 and CPU1 has called up_cpu_paused to CPU0, hence 26270 g_cpu_irqlock has been locked by CPU1, in this case, we would see a 26271 deadlock in later call of enter_critical_section() to restore 26272 irqcount. To avoid this situation, we need to call 26273 enter_critical_section() to break the deadlock. From Masayuki 26274 Ishikawa. 26275 26276 * Atmel SAM3/4 Boards: 26277 26278 - SAM4CM: Fix cpustart() implementation. In Cortex-M, offset 0 in 26279 vector table stores initial stack pointer and offset 4 stores reset 26280 vector. From Masayuki Ishikawa. 26281 26282 * Atmel SAMA5Dx Boards: 26283 26284 - SAMA5D4-EK: Fix bad conditional compilation for 26285 board_app_initialize(). Should depend only on CONFIG_LIB_BOARDCTL, 26286 CONFIG_BUILD_KERNEL is irrelevant. From Gregory Nutt. 26287 26288 * Microchip i.MXRT: 26289 26290 - i.MXRT WFI: WFI needs to be disabled on i.MXRT. We found the 26291 reason: The imxrt1050 is configured to use SYSTICK for the kernel 26292 timer, but SYSTICK cannot wake up the MCU from low-power modes. 26293 Disable low-power modes on this MCU until we have support for an 26294 alternative timer. Earlier versions of the board (EVK, not EVKB), 26295 had A0 silicon which by default did not enter low-power mode on a 26296 WFI. With this change in place together with the previous one my 26297 system is stable, just using more power than it should. From Dave 26298 Marples. 26299 26300 * Microchip i.MXRT Drivers: 26301 26302 - i.MXRT Serial: TC (Transmission complete) and TDRE (TX Buffer 26303 Empty) were transposed in imxrt_serial.c. The end result was that 26304 for unoptimized code everything worked fine, but optimized code got 26305 itself into a real mess and continually fired interrupts. From Dave 26306 Marples. 26307 26308 * Microchip i.MXRT Boards: 26309 26310 - IMXRT1020-EVK: Make naming of the LED consistent. In most places 26311 it is referred to as LED1. In board.h it is referred to as 26312 USERLED1. The i.MXRT1020-EVK hardware user guide (HUG) uses the 26313 name USERLED. This command makes all names internally consistent 26314 and consistent with the HUG. Noted by Alin Jerpelea. From Gregory 26315 Nutt. 26316 26317 * NXP/Freescale Kinetis Boards: 26318 26319 - TWR-K60N512: Suppress errors related to card detect GPIO 26320 configuration if SDHC support is not enabled. From Gregory Nutt. 26321 26322 * NXP LPC17xx/40xx Drivers: 26323 26324 - lpc17xx/40xx I2C: Respect the I2C_M_NOSTART flag. Sending a 26325 restart condition when not requested will break other drivers that 26326 depend on this behavior. From Augusto Fraga Giachero. 26327 - LPC17xx/40xx Ethernet: Use usleep() instead of up_delay() for large 26328 wait times. From Augusto Fraga Giachero. 26329 26330 * NXP LPC54xx: 26331 26332 - LPC54 Clocking: Fix PLL settings. For the lpc54628 Rev. E board 26333 the PLL was not configured properly and the board would not boot 26334 correctly. I checked the startup files from the official IDE and 26335 inspected the assembly instructions for the libraries used. From 26336 Andrei Stefanescu. 26337 26338 * NXP i.MXRT Boards: 26339 26340 - IMXRT1060-EVK: Fix FT5X06 CTRSTn pin configuration, increased 26341 number of pollwaiters for the FT5X06, tuned resolution during 26342 pointer dragging. From Fabio Balzano. 26343 26344 * On Semiconductor Boards: 26345 26346 - LC823450: Fix cpustart() implementation. In Cortex-M, offset 0 in 26347 vector table stores initial stack pointer and offset 4 stores reset 26348 vector. From Masayuki Ishikawa. 26349 - LC823450-XGEVK: Fix build error for posix_spawn. From Masayuki 26350 Ishikawa. 26351 26352 * Sony CXD56xx: 26353 26354 - CXD56xx Assertions: Replace some assertions with error return 26355 values. From Alin Jerpelea. 26356 - CXD56xx Interrupts: Fix hang-up when error interrupt occurs. From 26357 Alin Jerpelea. 26358 - CXD56xx Pin Configuration: PIN_AP_CLK is used as a port selector of 26359 SDIO expander on the extension board, and is set output low in 26360 initialization. Therefore, this pin cannot be used by the other 26361 board. To avoid this restriction, remove this initial operation 26362 because this pin is pulled down by default on the extension board. 26363 From Alin Jerpelea. 26364 - CXD56xx: Remove duplicate NVIC_SYSH redefinitions. The NVIC_SYSH 26365 is already defined in nvicpri.h From Alin Jerpelea. 26366 26367 * Sony CXD56xx Drivers: 26368 26369 - CXD56xx SDHCI: Fix initial value of semaphore in sdhci driver. 26370 From Alin Jerpelea. 26371 26372 * Sony CXD56xx Boards: 26373 26374 - Spresense: The SD Card TXS02612 port expander is hosted on the 26375 Extension board and should not be enabled if the extension board is 26376 not present. From Alin Jerpelea. 26377 26378 * STMicro STM32: 26379 26380 - STM32 F4 Pin Multiplex: Ethernet pin ETH_RMII_REF_CLK is an input. 26381 From Gregory Nutt. 26382 - STM32 H7 ADC: Fix typos in ADC register definitions. From Markus 26383 Bernet. 26384 - STM32 H7: Heap allocation, SRAM and SRAM1 are not continuous From 26385 David Sidrane. 26386 - STM32 H7 CRC: Add the CRC option in KConfig. From Eduard Niesner. 26387 - STM32 H7 RCC: Add PLL3 Support and only enable PLLs if used. From 26388 David Sidrane. 26389 - STM32 L4x6xx RCC: This fix is needed if HSI clock is selected. 26390 Otherwise when waking up from STOP mode, the MSI clock is selected 26391 instead of the HSI clock. From Matias N. 26392 26393 * STMicro STM32 Drivers: 26394 26395 - STM32 USB Host: There was no relationship between 26396 CONFIG_STM32_USBHOST and CONFIG_USBHOST, yet they they were used 26397 interchangeably. This means that can (and did) get out of synch 26398 causing link time failures. This change adds logic to select 26399 CONFIG_USBHOST when CONFIG_STM32_USBHOST is selected, keeping the 26400 two settings synchronized. Furthermore, since CONFIG_STM32_USBHOST 26401 is the authoritative setting, all occurrences of CONFIG_USBHOST were 26402 replaced with CONFIG_STM32_USBHOST. From Gregory Nutt. 26403 - STM32 SDIO: SDIO Fix system hang on card eject. From David Sidrane. 26404 - STM32 F7 Ethernet: Large Ethernet packet can leads network halt. 26405 From Bazooka Joe. 26406 - STM32F7 OTGHOST: OTGFS_EPTYPE_INTR should be OTG_EPTYPE_INTR. From 26407 Gregory Nutt. 26408 - STM32 F7 SDMMC: SDMMC Fix system hang on card eject. From David 26409 Sidrane. 26410 - STM32 L4 Firewall: Correct a test to determine if an address lies 26411 in FLASH or not. Improper mask caused test to always fail. From 26412 Gregory Nutt. 26413 - STM32 H7 Ethernet: Bazooka Joe's fix to the STM32 F7 Ethernet 26414 driver should be applied to the H7 as well. The other STM32 26415 Ethernet drivers already have the change. From Gregory Nutt. 26416 - STM32 H7 Ethernet: Fix ETH_MACMDIOAR_CR_MASK bit mask. From Markus 26417 Bernet. 26418 - STM32 H7 SDMMC: SDMMC Fix system hang on card eject. From Gregory 26419 Nutt. 26420 - STM32 H7 FLASH: Flash driver BUG fixes. From David Sidrane. 26421 - STM32 H7 TIM: Correct register bit definitions and alternate 26422 functions. Fix other copy-paste definitions. From Daniel Pereira 26423 Volpato. 26424 - STM32 L4 SDMMC: SDMMC Fix system hang on card eject. From David 26425 Sidrane. 26426 26427 * STMicro STM32 Boards: 26428 26429 - STM32F4-Discovery: Fix build error for posix_spawn. From Masayuki 26430 Ishikawa. 26431 26432 * TI Tiva: 26433 26434 - TIVA IRQs: Fix wrong IRQ vector number. From Nathan Hartman. 26435 - Tiva FLASH: Fix several mistakes in tiva_write(). (1) Fix wrong 26436 use of && when & was intended. (2) Add compile- time warning 26437 directive because according to this function's interface, it is 26438 supposed to support unaligned writes and/or writes of arbitrary 26439 numbers of bytes to FLASH. However, this function does NOT support 26440 that at this time. This needs to be fixed. (3) Fix wrong 26441 preprocessor conditional. Was written to use the 32-word write 26442 buffer only for TM4C1294NCPDT. This buffer is available on all 26443 M4C123 and TM4C129 parts. Now conditioned upon 26444 CONFIG_ARCH_CHIP_TM4C123 or CONFIG_ARCH_CHIP_TM4C129. (4) Add 26445 comments to document the intent of the above preprocessor logic. 26446 From Nathan Hartman. 26447 26448 * Xtensa 26449 26450 - Xtensa: Apply Masayuki Ishakawa's change for ARMv7-M to this SMP 26451 architecture as well. From Gregory Nutt. 26452 26453 * Build System: 26454 26455 - Makefiles: Change ${shell pwd} to $(CURDIR) since pwd doesn't exist 26456 on Windows From Xiang Xiao. 26457 - tools/Makefile.unix: Fix build error when issue 'make -B': "mkdir: 26458 cannot create directory 'staging': File exists: 26459 tools/Makefile.unix:269: recipe for target 'staging' failed". From 26460 Xiang Xiao. 26461 - All ARM linker scripts: Preface all _ebss definitions with '. = 26462 ALIGN(4)'. Otherwise, the following .bss section may not be aligned 26463 properly. From Gregory Nutt. 26464 - MIPS Linker Scripts: The PIC32M* start-up code initializes .bss by 26465 writing 16 bytes at a time in a loop. The start (_sbss) alignment 26466 is only required to be 4 bytes since the write is done with 4 store 26467 instructions. From Gregory Nutt. 26468 - Top-level Kconfig: Add some protection so that you cannot select an 26469 architecture-specific header file if the architecture does not 26470 provide the header file. From Gregory Nutt. 26471 - libc Kconfig: Should select the NuttX float.h file automatically 26472 if the NuttX math library is selected. From Gregory Nutt. 26473 - tools/Makefile.unix: Make COMMON_DIR work with 26474 CONFIG_ARCH_BOARD_CUSTOM. From Xiang Xiao. 26475 - tools/ Make fragments: Fix the various minor issue for NUTTXLIBS / 26476 USERLIBS: (1) Remove libcxx duplication in FlatLibs.mk and from 26477 kernel space, (2) Remove libpass1 from KernelLibs.mk since kernel 26478 build doesn't support the two pass mode, and (3) Remove FSDIR 26479 related comment since file system cannot be disabled now From Xiang 26480 Xiao. 26481 26482 * C Library/Header Files: 26483 26484 - getcwd(): Remove stray sched_unlock(). Also fixes several typos. 26485 From Juha Niskanen. 26486 - date(), hostname(): Fix portability issue with date, hostname From 26487 David Alessio. 26488 - libs/libxx/Kconfig: Automatically select CONFIG_CLOCK_MONOTONIC when 26489 CONFIG_LIBCXX is selected. Removed hardcoded -DCLOCK_MONOTONIC from 26490 CFLAGS in Make.defs of several configurations. That definition is 26491 now automatically adding this define when CONFIG_LIBCXX=y. From 26492 Daniel Pereira Volpato. 26493 - libs/libxx/Kconfig: CONFIG_LIBC_LOCALE is needed to build libcxx. 26494 A math library is also needed, however, there are various ways to 26495 provide a math library so CONFIG_LIBM is not now set. From Matias 26496 N. 26497 - libs/libc/symtab: Move symbol table generation into libc since the 26498 address in symbol table should come from userspace binary for 26499 PROTECTED build, not kernel binary. From Xiang Xiao. 26500 - libs/libc/ Kconfig files: Disable EXECFUNCS_HAVE_SYMTAB for kernel 26501 build. The symbol table doesn't have any meaning for kernel build 26502 since all executable binary should be self contained. From Xiang 26503 Xiao. 26504 26505 - include/sys/time.h: According to earlier standards, usage of 26506 select(), FD_CLR, FD_ISSET, FD_SET and FD_ZERO just need include 26507 headers: sys/time.h, sys/types.h and unistd.h. So include 26508 sys/select.h in time.h to compatible with it. Or mbedtls library 26509 would build break in calling select() and FD_* related functions. 26510 From liuhaitao. 26511 26512 * Tools: 26513 26514 - tools/configure.sh and configure.c: Do not remove CONFIG_SIM_M32 if 26515 host is specified. From anchao. 26516 - tools/Directories.mk: Remove FSDIRS/NOFSDIRS related logic/comments 26517 since the file system can no longer be disabled now. From Xiang 26518 Xiao. 26519 - tools/Makefile.host: Add missing binaries from clean target. From 26520 Gregory Nutt. 26521 - tools/mkromfsimg.sh: Use sed to add const to ROMFS declarations so 26522 that they lie in FLASH not RAM. From Bernd Walter. 26523 - tools/nxstyle.c: Correct detection of missing blank line following 26524 a block comment. From Gregory Nutt. 26525 26526 * apps/ Build System: 26527 26528 - Makefiles: Change ${shell pwd} to $(CURDIR) since pwd doesn't exist 26529 on Windows From Xiang Xiao. 26530 - Makefile: Fix warning: jobserver unavailable: using -j1. Add '+' to 26531 parent make rule. From Xiang Xiao. 26532 - apps/Application.mk: Correct an error in PATH usage. Use of 26533 toolchain path causes make errors. From Gregory Nutt. 26534 26535 * apps/tools: 26536 26537 - tools/mkromfsimg.sh: Use sed to add const to ROMFS declarations so 26538 that they like in FLASH not RAM. From Bernd Walter. 26539 26540 * Examples: apps/examples: 26541 26542 - apps/examples/mount: Replace illegal call to ramdisk_register() 26543 with a call to boardctl(BOARDIOC_MKRD). From Gregory Nutt. 26544 - apps/examples/nxlines/: Correct nxlines example program name. From 26545 Gregory Nutt. 26546 - apps/examples/nxterm/: PROGNAME, PRIORITY, STACKSIZE variable 26547 names did not match declarations in Kconfig file. From Gregory 26548 Nutt. 26549 - apps/examples/romfs: Remove romfs_testdir.h. That file is 26550 regenerated whenever the example is built and so should not be in 26551 the repository. From Gregory Nutt. 26552 26553 * Testing: apps/testing: 26554 26555 - apps/testing/cxxtest/: Fix typo error in testing/cxxtest. From 26556 Xiang Xiao. 26557 - apps/testing/unity/: Fix the error when creating Make.dep. From 26558 raiden00pl. 26559 26560 * NSH Library: apps/nshlib: 26561 26562 - apps/nshlib: Remove the inappropriate NSH_BUILTIN_APPS coupling. 26563 From Xiang Xiao. 26564 - apps/nshlib/: The NSH mkrd command was in violation of the NuttX 26565 portable POSIX interface. It was calling the internal OS function 26566 ramdisk_register() directly. Not only is this a violation of the 26567 interface specification, but also prevents use of mkrd in PROTECTED 26568 or KERNEL builds. With this change, the NSH mkrd command now uses 26569 the BOARDIOC_MKRD boardctl() command. This command is available in 26570 all build modes. The effect of this change is to move the heart of 26571 the NSH mkrd command into to OS and provide user-space access via 26572 boardctl(). From Gregory Nutt. 26573 - apps/nshlib/: Replace direct calls to romdisk_register() with 26574 indirect calls via boardioctl(BOARDIOC_ROMDISK). This not only 26575 fixes the violation of the portable POSIX OS interface, but also 26576 permits use of ROM disks in PROTECTED and KERNEL modes. From 26577 Gregory Nutt. 26578 - apps/nshlib/: Add missing NSH_DISABLE_DMESG from Kconfig. From 26579 Juha Niskanen. 26580 26581 * System Utilities: apps/system: 26582 26583 - apps/system/cle/: This change modifies the cle to use the streams 26584 file interface more consistently and has removed the observed race 26585 conditions. It was previously a mix of streams and fileio. It 26586 also simplifies the VT100 cursor position handling. From Dave 26587 Marples. 26588 - apps/system/composite: Remove usb serial loopback test code we can 26589 achieve the same effect by cat or dd command. From Xiang Xiao. 26590 - apps/system/cu/: (1) Fix early exit. getc(stdin) can return 0 the 26591 first time around. (2) Set optind to zero. getopt() was being 26592 left in a bad state, causing parsing errors on second use. (3) Fix 26593 priority of cu_listen(). (4) Add suppor for -h. From David 26594 Alessio. 26595 - apps/system/lzf/: Check the protection by CONFIG_SYSTEM_LZF != 26596 CONFIG_m (not elf binary) instead of CONFIG_KERNEL_BUILD. From 26597 Xiang Xiao. 26598 - apps/system/spi: Correctly parse exch txdata args, if any. Should 26599 always call the board's deselect From David Alessio. 26600 26601 * File System Utilities: apps/fsutils: 26602 26603 - apps/fsutils/passwd/: Use named semaphore by checking 26604 CONFIG_FS_NAMED_SEMAPHORES instead of CONFIG_KERNEL_BUILD. From 26605 Xiang Xiao. 26606 26607 * Network Utilities: apps/netutils: 26608 26609 - apps/netutils/cjson/Makefile: Fix the error when creating 26610 Make.dep. From raiden00pl. 26611 26612 * Graphics: apps/graphics: 26613 26614 - apps/graphics/twm4nx/: Fix a recently introduced error that broke 26615 all Twm4Nx configurations. From Gregory Nutt. 26616 - apps/graphics/traveler/: Replace direct calls to romdisk_register() 26617 with indirect calls via boardioctl(BOARDIOC_ROMDISK). This not only 26618 fixes the violation of the portable POSIX OS interface, but also 26619 permits use of ROM disks in PROTECTED and KERNEL modes. From 26620 Gregory Nutt. 26621
