8289 - apps/netutils/netlib: Add utilities to convert to/from prefix
8290 lengths from/to 128-bit network masks.
8291 - apps/nshlib: Modify the NSH IPv6 ifconfig command to show the more
8292 standard post-pended prefix value, rather than the full 128-bit
8299 * Processes. Much of the work in this release is focused on the
8300 realization of Unix-style user processes in NuttX. There is more to
8301 be done, however. The full roadmap and status is available at:
8313 - Work Queues: Fix a backward calculation when determining the time
8316 - clock_systimespec(): Fixes for compilation errors in certain
8321 - Fixed a problem with one of the font files. From Pierre-noel Bouteville.
8325 - IOB Deadlock: There were issues with the TCP write-ahead buffering
8326 if CONFIG_NET_NOINTS was enabled: There is a possibility of
8328 wait for TCP read-ahead buffering space to be available. It should
8329 drop the packets immediately if no buffering is available. This was
8331 waited are still present (like iob_alloc()), but now there are non-
8333 TCP read-ahead logic now uses only these non-waiting interfaces.
8334 - TCP Deadlock: Fix another deadlock when CONFIG_NET_NOINTS is enabled.
8338 CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad
8340 - ARP response waiting: Fixes another CONFIG_NET_NOINTS issue. When
8342 locked while we wait which is not what we want (without CONFIG_NET_NOINTS,
8343 interrupts are re-enabled while we wait and all is well).
8344 - TCP accept(): Fix a major TCP bug introduced with the NuttX-7.7
8350 okay. So the symptom was connect-fail-connect-fail-...
8351 - Lots of build problems introduced into multiple NIC support with the
8352 IPv6 changes of NuttX-7.7. Many places where conditional logic based
8353 on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK.
8359 - Pipes and FIFOs: Fix a race condition between FIFO buffer operations
8362 policy is the deallocate FIFO buffering when the last client closes
8364 in the FIFO will be lost. Some like UDP read-ahead is needed: The
8366 a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to
8367 control the buffer policy. Default (0) is the legacy behavior; Unix
8369 data persists after the FIFO is closed.
8370 - RAMTRON: Table of parts is not terminated properly if
8371 CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined. Noted by David
8376 - Removed all occurrences of up_maskack_irq() that disables interrupts
8377 with up_ack_irq() that only acknowledges the interrupts. This is only
8379 unconditionally re-enables interrupts with the interrupt exits. This
8381 This is a necessary, sweeping, global change and unfortunately
8386 - ARMv7-A and ARMv7-M memcpy(): Optimized ARM assembly language
8389 - ARMv7-A interrupt handler should not automatically re-enable interrupts
8396 - GPIO Interrupts: Disabling any of EXTI 5-9 interrupts was disabling
8397 interrupts for all EXTI 5-9. Same issue with EXTI 10-15. From Jussi
8402 - RTCC: Fix for recent changes that caused compilation failrues with
8404 - SPI: The source clock for SPI 4,5, and 6 should be PCLK2, not PCLK1
8409 - execl(): Fix bad logic in counting the number of arguments.
8411 Pierre-noel Bouteville.
8415 - Fix for building with parallel make. Build-server sometimes failed
8416 'make -j24' with errors in the builtin line or or sometimes silently
8420 not linearizable, and (2) Nothing ensures that 'make context' is run

8598 - PPPD test: Add PPPD test case. Split out from the PPPD daemon by
8600 - Netutils: Add a PPP daemon. From Max Neklyudov.
8601 - NSH: NSH initialization now calls boardctl(BOARDIOC_INIT) instead
8603 It is not used and there are better ways to do that operation.
8604 - NSH: Allow NSH 'date' command with no hardware RTC. This command
8605 is useful without an RTC too. Also, this permits testing on the
8607 - apps/examples/: Several tests changed (touchscreen adc, pwm,
8610 - Modbus: Includes extensions to support RTU master mode by
8611 Armink(383016632@qq.com): https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32.
8613 - TZ database: All logic to build timezone database needed for
8620 * Processes. Much of the work in this release is focused on the
8621 realization of Unix-style user processes in NuttX. There is more to
8622 be done, however. The full roadmap and status is available at:
8634 - atexit(): Fix compile failure due to reference to undefined variable
8636 - syscalls: Last changes to message queue prototypes did not make it
8639 - waitpid(): Do not use uninitialized boolean in waitpid(). From Juha
8641 - Timing functions: Fix some nanosecond comparisons. Comparisons should
8644 - Time initialization: Fix an error in time initialization when there
8645 is no RTC and the time is initialized from a fixed configured value.
8650 time is not visible.
8651 - mq_timedsend(): Should not check for valid time if there is space
8653 - select() and sem_timedwait(): Fix places where the errno value was
8656 - clock_systimer64(): Fix a problem in clock_systimer64 that occurs
8657 when (1) the 64-bit system time is enabled, and (2) the value of
8658 CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using
8660 time to 64-bit millisecond value in clock_systmer64() causes some
8663 conversion. The fix is to first convert time to a 64-bit microsecond
8665 - clock_systimespec(): When an RTC is used clock_systimespec() must
8669 - AIO: correct some backward tests in aio_read() and aio_write():
8676 - procfs: Fix potential NULL pointer dereference of 'node'. From
8678 - FAT: fat_unbind() was accessing 'fs->fs_sem' after freeing the 'fs'
8680 - mkfatfs: Use DMA memory for mkfatfs when needed. This makes mkfatfs
8681 use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is needed
8684 - FAT unmount: Fix a bug in the FAT unbind() logic. There were
8686 implemented. The end result is that newly opened or cloned file
8690 - FAT mounting: Fix misthink when CONFIG_ENDIAN_BIG=y. From Lwazi Dube.
8694 - CAN upper half driver: Some lines had to be reordered in the can_open
8701 - crypto: Fix issues when AES support was added for the STM32L1.
8706 - Network initialization: Divide net_intiialize() into net_setup() and
8707 net_initialize() to solve a chicken-and-egg problem. net_setup()
8708 must be called before up_initialize() is called so that networking
8710 net_initialize() now does only timer related operations and is
8713 - netdev_unregister(): Fix a list handling error. From Max Neklyudov.
8714 - Socket dup: Do not call sockfd_socket() twice. From Juha Niskanen.
8718 - max11802 touchscreen: Fix possible unmatched IRQ restore (not
8721 - MMCSD SPI Multi-block transfers: ACMD23 must be preceded with CMD55

8727 - Common upper-half serial driver: Report correct number of bytes free
8729 - Pipes/Fifos: Fix zero-lenth writes to pipes/FIFOs. From Jussi Kivilinna.
8730 - USB device MSC: Add NULL pointer check. From Juha Niskanen.
8731 - BCH driver: Avoid NULL pointer dereference when bch->refs == 255.
8733 - Various drivers: The inode unlink method should not be support if
8734 operations on the root pseudo-filesystem are disabled.
8736 * ARMv7-M
8738 - ARMv7M MPU: Bad syntax in ARMv7-M MPU logic would cause failure to
8743 - SAM3/4 Serial TERMIOS: A side-effect of changing serial settings
8744 via TERMIOS (such as tcsetattr) is that serial interrupts were being
8745 left disabled. This is not a problem if the serial configuration is
8748 enabled until the serial device is first opened. But it is fatal if
8749 the serial device is already opened and if there is a task waiting
8750 to receive data. In that case, the side-effect of disabling
8751 interrupts is fatal: That task is then left hanging with interrupts
8753 - SAM3/4 Serial: The IMR register is read-only. This means that
8754 sam_restoreints() did not actually re-enable UART interrupts
8756 - SAMA5 HSMCI: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift
8763 - SAMA5 Timer/Counter: Fix typos in timer/counter header file. From
8768 - STM32 PWR and RTC: Changes to support fully write protecting the
8770 from enable to the domain being writable. The KISS solution is a
8773 - STM32 SPI: Add missing SPI callback functions to the STM32 SPI
8775 - STM32 I2C: Add missing NULL check. From Juha Niskanen.
8776 - STM32 USB device: Fix stale initialization invalidating later NULL
8778 - STM32 UART: Fix RX DMA setup for UART5. From Jussi Kivilinna.
8779 - STM32 UART: Make input hardware flow-control work with RX DMA. From
8781 - STM32 RTC and clock control: The STM32F4Discovery board doesn't
8786 clock; but the next times, when the rtc is already setup, the
8788 put LSE/LSI initialization is inside stm32_stdclockconfig() in
8792 This change is not verified for any other platforms. From Leo
8797 - Tiva GPIO driver needed small fixes in the configuration routines and
8798 discovered false-positive bugs in interrupt testing: interrupts are
8803 - mips32/Toolchain.mk: Current Pinguino toolchain uses the prefix p32-
8804 instead of mips-.
8808 - sigaddset() and sigdelset(): Need to set errno if a bad signal
8809 number is received.
8810 - sfrtime(): Missing implementation of %C in sfrtime() C (was being
8812 - pthread.h: Fix PTHREAD_COND_INITIALIZER.
8813 - ungetc.c: Fix NULL pointer dereference in ungetc() if 'stream' was
8814 NULL, 'stream->fs_oflags' was evaluated. From Juha Niskanen.
8815 - Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all
8816 exhibited bad cancellation errors near zero (<= 1E-10). This can be
8817 easily seen e.g. with x = 1E-30, the results are all zero though they
8818 should be extremely close to x. The cutoff values (1E-5, 1E-9) are
8819 chosen so that the next term in the Taylor series is negligible (for
8822 - localtime(): Inconsistent configuration name: CONFIG_LIBC_TZDIR vs
8827 - Modbus: Fix some compile problems when TCP is enabled.

9036 be done, however. The full roadmap and status is available at:
9048 - boardctl(): Add missing case causing that caused failures of PWM
9050 - pthread_kill(): Re-implemented pthread_kill(). It was just a simple
9052 for multi-threaded task groups has been implemented, calling kill()
9053 does not do what pthread_kill() is supposed to do. The corrected
9056 - uint32_t callbacks: Update the type passed to watchdog timer
9057 handlers. Using uint32_t is a problem for 64-bit machines because
9058 it is too small to pass a pointer. uintptr_t is a more appropriate
9060 - mq_timedreceive(): move the location where the errno value is set;
9063 - POSIX message queues: Move mq_setattr() and mq_getattr() from
9065 for mq_setattr() and mq_getattr(). This is necessary in protected

9112 - TCP: Fix an important TCP networking bug: 16-bit flags was being
9113 converted to 8-bits in a few locations, causing loss of status
9115 - TCP: net_startmonitor() always returned OK. In the race case
9122 - setsockopt() failed when setting timeouts to values less tha 100
9123 msec. That is because the timeout is limited to stops of 1
9129 non-zero remainder to the next larger whole decisecond value. Bug
9131 - TCP: In the TCP connection operation, it was trying to setup the
9133 of course, has ALWAYS failed because the socket is not yet connected
9134 and the TCP state is not yet correct for a connected socket. However,
9137 is to move the logic that starts the network monitor to AFTER the
9142 - SAM4CM and SAMA5D Free-running timer: Logic that samples the free
9144 cause interrupts to be lost. So, if when the status register is

9430 configuration file has been removed and now the top-level Makefile
9431 executes tools/mkkconfig.sh to auto-generate the top-level Kconfig
9433 this operation. Now you do not have to modify the top-level Kconfig
9434 file to add a new directory into the configuration; the top-level

9617 - Nx Lines example: If CONFIG_NX_ANTIALIASING=y, then the nxlines
9618 example now erases a line that is 2 pixels longer and 2 pixels wider
9620 applying the anti-aliasing algorithm twice. A better solution
9621 would be to make anti-aliasing an option for each graphics call so
9622 you would rend the line with anti-aliasing ON and clear it with
9623 anti-aliasing OFF. but I don't have the wherewithal for that change
9625 - OS test: Improve synchronization in round robin tests. On very fast

9825 data transfers can cause crashes. The fix is to lock into a single
9826 device once the MSS is locked locked down.
9827 - net/tcp: The logic that binds a specific network device to a

9849 - ARMv7-M, all "lazy" interrupt stack logic. Assembly instruction
9850 that fetches the saved value is incorrect; replace with more
9851 traditional push and pop. This is an important fix. Noted by
9853 - All ARMV7-M: Force 8-byte stack alignment when calling from assembly
9855 - up_schedulesigaction(): Fix logic that determines if there is a
9858 problem was fixed on the ARMv7-M but also ported to other

10460 apps-7.15.tar.gz. These are available from:
10465 Both may be needed (see the top-level nuttx/README.txt file for build
10472 - Add a state variable that provides the current level of OS

10632 group. I know, I preferred it the other way too, but this is more
10634 - Semaphores: Add an internal, non-standard interface to reset a
10635 semaphore count. This is sometimes needed by drivers in order to
10637 which is both inappropriate and incorrect if the semaphore count is
10639 - Low-Priority Work Queue: Fix logic to find an IDLE worker thread;
10644 - FAT: Add an option to force all transfers to be performed
10646 This is a fix for the case where the user provided buffers are not

10652 - I2C: Restructured the I2C interface as necessary to eliminate some
10653 thread-safety issues inherent in the legacy I2C interface design.
10654 This effects the interface definition, all I2C clients, and all low-
10658 - I2C_RESET: Eliminate up_i2creset(). It should not be a global
10659 function; Now it is an I2C interface method.

10671 - Timer Poll: Fix some logic when there are multiple network
10673 processed when the poll from the correct device is received.
10677 - SAMV7 USB HS device: The USB driver has had some issue that would
10680 causing hangs. The basic problem is that the number of busy banks
10681 (NBUSYBKS) status is not real time but is delayed. This was fixed;
10682 now when the DMA completes and NBUSYBKS > 0, the NBUSYBK is
10683 interrupt is enabled and the operations are deferred until NBUSYBKS
10684 is truly zero.
10688 - tools/testbuild.sh: .config files were not being updated because
10689 (a) kconfig-conf was being called in the wrong directory and (b)
10695 - apps/system/i2c: The I2C tool now obeys it OS interfacing: it now

10707 - apps/modbus/nuttx/portserial.c: Was not returning an error on
10712 - apps/examples/usbserial, composite, usbterm: Use new boardctl()
10719 - Moved C++ initialization logic out of the RTOS and into the

10777 expander and supports the HD44780-based (or compatible) LCD modules.
10785 - RTC: Simplify the RTC interface. The old interface was way too
10787 - BH1750FVI: Add a character driver for Rohm Ambient Light Sensor

10824 - SAMV71-XULT: Add configuration(s) that were be used to verify VNC
10829 - Sabre-6Quad: The basic i.MX6 port is complete. This is a minimal
10830 port at present and probably still has some as-of-yet-undiscovered
10832 - Sabre-6Quad: Basic SMP NSH configuration is now working. But this
10833 is probably only because the SMP test case does not stress the
10835 Sabre-6Quad README.txt file.
10839 - LPC4337jet100: Add definitions for the LPC4337jet100 chip. From
10844 - AES: Add AES support. From Alexander Vasiljev.

10930 Works-In-Progress:
10933 introduced in NuttX-7.15. Work has continued on this effort on
10936 least NuttX-7.17.
10938 * i.MX6 SMP. Partially functional, but there is more that still
10947 - Various places: Search for places where a stray semicolon following
10950 - enter/leave_critical_section() may attempt to access task lists
10955 - SMART MTD: Return code of smart_scan not checked, can cause success
10958 - mount: Fix a backward debug assertion. Noted by David Sidrane.
10962 - NRF24L01: Fix backward calculation of relative frequency. Noted by
10964 - PCA9555 I/O expander: Fix an error in the PCA9555 driver: Under
10965 certain error conditions, interrupts were not being re-enabled.
10967 - ADS1255: Must not do SPI access from interrupt handler. Use the
10969 - Several SPI-based drivers modified. All drivers that use SPI must
10970 call SPI_LOCK and SPI_UNLOCK. This is not optional.
10971 - MS583730: Fix a bug in crc computation for ms583730. Implement
10976 - Fix typo in MATRIX register definitions. From Stefan Kolb.
10977 - SAMV7 Tickless Mode: This is a fix to a problem in the handling of
10981 assumes that the counter register is zero directly after the start
10982 of the timer, but this is not true. To start the time/counter a
10983 software trigger is invoked, this trigger starts the timer/count and
10985 register is not performed instantly. According to the datasheet:
10988 Thus the counter is set to zero between 0 and USEC_PER_TICK
10992 the oneshot counter is correct. I also tried to use the function
10996 Another problem treated in the fix is that if the oneshot timer/counter
10997 is canceled, we only know the remaining time with a precision of
10999 is between 0 and USEC_PER_TICK microseconds too long. To fix this I
11000 subtract one tick if the calculated remaining time is greater than
11007 - SAMA5: Stefan Kolb's change to the SAMV7 Oneshot Timer should also
11012 - SAM3/4: Stefan Kolb's change to the SAMV7 Oneshot Timer should also
11017 - SAMV7 TWIHS (as well as SAM3/4 and SAMA5: Ensure that the TWIHS
11020 sam_i2cbus_initialize() or twi_reset() is called. I found this a
11021 while back in the stm32 family, so there may be more arch-es with
11023 not set the freq if it is already set" could be suspect. From David
11025 - USBHS Device: Remove disabling of whole USB on suspend of USBHS.
11028 disabling the whole peripheral, the next wakeup-interrupt comes up
11030 the master clock is disabled. This makes all registers, including
11034 - MCAN: Fix missing unlock of device in MCAN mcan_txempty(). From
11039 - STM32 L4 Clocking: Problem with resetting backup domain clears
11048 - STM32L4 SPI: That STM32Lr SPI driver is quite different. They now
11050 before a new bit has to be set (RX fifo threshold) to handle <= 8-bit
11051 transactions. If not set, the default is 16-bit packed >=8-bit
11052 frames and the RXNE bit is never set (it is set when 16-bits are
11053 received). weird things as always. This also add 8-bit access
11054 routines to the data register, because a 16-bit access to the data
11055 register when the frame size is below 9 bits is interpreted as a
11057 - STM32: Correct some bad commits that broke the LTDC display example.
11059 - STM32 F4 RTC: Fix logic in F4 RTCC driver that prevent ALARM
11061 - STM32 F1 ADC: Fix STM32 ValueLine ADC IRQ number selection. From

11071 - GPIO Interrupts: Fix a bug of GPIO falling-edge interrupt for tiva.
11076 - math: Add a NAN test on 'x' in asin function of lib_asin.c. Suggested
11077 by Pierre-noel Bouteville.
11081 - Several Makefiles: Add .PHONY definitions to prevent 'clean up to date'
11082 message weirdness when 'make clean' is done with no .config or
11085 NuttX-7.17 Release Notes
11086 ------------------------
11089 and is available for download from the Bitbucket.org website. Note
11090 that release consists of two tarballs: nuttx-7.17.tar.gz and
11091 apps-7.17.tar.gz. These are available from:
11096 Both may be needed (see the top-level nuttx/README.txt file for build
11103 - drivers/mtd: Add a driver of IS25xP SPI flash devices. Based on
11108 - Break out internal interface psock_ioctl().
11112 - PTYs: Added support for pseduo-terminals: Device drivers that can be
11113 used for communications between tasks (usually with re-directed I/O).
11115 - Button upper half driver: Added support for poll().
11116 - CAN: Add support for poll. From Paul Alexander Patience.
11117 - GPIO: Add support for a simple GPIO driver. It supports only pre-
11121 - I/O Expander: Shadow-Mode: The output- and configuration registers of
11122 the IO-Expander are held in the microcontrollers memory and only
11123 written to the IO-Expander. This reduces bus traffic and is more
11124 error-proof than the normal read-modify-write operation. Retry Mode:
11125 If enabled and an error occurs while writing to the IO-Expander the
11126 current transmission is automatically repeated once. From Michael
11128 - Pipes/FIFOs: Add support to allocating different sizes for pipe and
11130 and pipe(), but allow control of the size of the underlying, in-memory
11137 - SYSLOG: Consolidated all SYSLOG logic in drivers/syslog. Added an
11139 This is usually so that you can boot with one SYSLOG output but
11143 will be asynchronous. And (3) vsyslog is now a system call and is
11144 usable with other-than-FLAT builds.
11145 - SYSLOG: syslog() will now automatically redirect output to
11147 - Extended SYSLOG logic so that we can send SYSLOG output to a file.
11148 - SYSLOG character device channel will now expand LF to CR-LF.
11150 - Add a SYSLOG character device that can be used to re-direct output
11153 - Debug features are now enabled separately from debug output.
11154 (1) CONFIG_DEBUG is gone. It is replaced with CONFIG_DEBUG_FEATURES.
11164 - Since the SYSLOG layer now automatically handles low-level vs.
11165 high-level output, the low-level (ll) variants of the debug macros
11167 - Reviewed all uses of *err(). These macro family should indicate
11169 ERROR:, depending on if an error is reported.
11170 - _alert(): New debug macro: _alert(). This is high priority,

12073 - slip driver: Fix calculations using MSEC_PER_TICK. If
12074 USEC_PER_TICK is less than 1000, then MSEC_PER_TICK will be
12079 - SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is
12080 configured as input. The value of a GPIO input is only sampled when
12081 the peripheral clock for the port controller the GPIO resides in is
12084 - All SAM Ethernet Drivers: Add support so that the drivers can be
12086 - SAM3/4: Fix GPIO pull-up/down code. Enabling the pull-down resistor
12087 while the pull-up resistor is still enabled is not possible. In this
12088 case, the write of PIO_PPDER for the relevant I/O line is discarded.
12089 Likewise, enabling the pull-up resistor while the pull-down resistor
12090 is still enabled is not possible. In this case, the write of
12091 PIO_PUER for the relevant I/O line is discarded. From Wolfgang

12111 - LPC43xx Serial: There are some small problems in LPC43xx RS485 mode
12123 - EFM32 SPI drivers adopted incompatible conventions (See STM32 for
12128 - STM32, STM32 L4, and EFM32 SPI drivers adopted incompatible
12130 to negative when calling SPI_SETBITS which had the magical side-
12131 effect of setting LSB first order of bit transmission. This is not
12132 only a hokey way to pass control information but is supported by no
12139 drivers: The number of bits is now always positive and
12140 SPI_HWFEATURES is called with HWFEAT_LSBFIRST to set the bit order.
12141 - Add missing SPI2 and SPI3 support for STM32F3F3. Add STM32F37XX DMA
12144 - STM32: Make stm32_pwr_enablebkp thread safe. From Max Neklyudov.

12190 - STM32 L4 USB Device: Fixed L4 USB Driver by avoiding SETUPDONE and
12192 - STM32 SPI: stm32_modifycr2 should be available on all platforms if
12193 DMA is enabled.
12194 - STM32 DMA2D: fix an error in up_dma2dcreatelayer where an invalid
12200 - Fix two bugs of tiva pwm lower-half driver implementation. From
12202 - Tiva Ethernet: Needs support for CONFIG_NET_MULTIBUFFER=y.
12206 - lib_dumpbuffer() now prints a large on-stack buffer first to avoid
12207 problems when the syslog output is prefixed with time. From
12208 Pierre-noel Bouteville.
12209 - libc/math: This fixes the following libc/math issues: (1) asin[f l]()
12218 x near -3.0. This patch fixes that problem. It should be noted that
12220 less than 1.2E-07 and that's fine for the float version erff(), but
12221 the same method is used for double and long double version which
12224 faster version of copysignf() for floats is included. From David S.
12226 - strtod() was not returning endptr on error conditions.
12227 - libc/math: floor(), floorf(), and floorl(): Fix logic error. Was
12229 - isatty() should be prototyped in unstid.h, not termios.h. From
12231 - nxglib: Fix handling of near-horizontal lines of width 1 in
12233 width 1 lines such as (0, 0) - (100, 10) to have gaps in the
12238 - Top-Level Makefiles: Fix a chicken-and-egg problem. In the menuconfig
12239 target, the context dependency was executed before kconfig-mconf. That
12242 Kconfig files would not be included. But this introduces the chicken-
12243 and-egg problem in some configurations. In particular: (1) An NX
12244 graphics configuration is used that requires auto-generation of
12245 source files using cpp, (2) the configuration is set for Linux, but
12247 In this case, POSIX-style symbolic links are set up but the Windows
12249 'make menuconfig' is to change from Linux to Cygwin, but the target
12250 fails. During the context phase, NX runs CPP to generate source files
12256 to run all of the context setup; the compiler is never invoked; no
12257 code is autogenerated and things work.
12258 - CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From
12263 - tools/refresh.sh: Recent complexities added to apps/ means that
12266 - tools/kconfig2html.c: Update to handle absolute paths when sourcing

12634 Works-In-Progress:
12637 introduced in NuttX-7.15. Work has continued on this effort on
12640 least NuttX-7.20.
12648 - sched/semaphore: Within the OS, when a thread obtains a semaphore
12649 count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is
12650 enabled. If a count is available, then sem_wait() calls
12660 - Many files: Make sure that priority inheritance is not enabled for
12661 semaphores whose primary use is signaling (vs locking of resources) by
12663 - sched/semaphore: sem_trywait() no longer modifies the errno value
12666 - sched/clock: Correct clock initialization. The correct range for the
12667 month is 0-11 but is entered as 1-12 in the .config file. Add ranges
12669 - sched/clock: Correct calculation for the case of Tickless mode with a
12670 32-bit timer. In that case, the calculation was returning millisecond
12671 accuracy. That is not good when the timer accuracy is < 1 msec. From
12673 - Work Queue: When queuing new LP work, don't signal any threads if
12675 - Work Queue: Signal sent from work_signal() may interrupt the low
12676 priority worker thread that is already running. For example, the
12677 worker thread that is waiting for a semaphore could be woken up by the
12679 does not make any sense to send signal if it is already running and
12681 - Fix DEBUGASSERT() in group_signal.c. From Masayuki Ishikawa.
12682 - Eliminate bad boardctl() commands: Remove all references to
12685 BOARDIOC_CAN_INITIALIZE. CAN initialization is now done in the board
12687 - pthreads: Fix an error in pthread_mutex_destroy(). An error could
12690 - task_restart: Make sure new task starts with pre-emption disabled and
12692 - Enter/leave Critical Sections. Major redeign to
12697 - SMP Critical Sections: Fixes for the SMP case: (1) Change order for
12699 BEFORE taking spinlock and (2) If SMP is enabled, if any interrupt
12701 - SMP wdogs: Wdog timers use a tasking interface that to manipulate
12703 to manage wdog expirations. In the single CPU case, this is fine.
12711 - SMP vfork(): Fix a race condition in the SMP case. Existing logic
12714 the SMP case that is not true... the child may run immediately on a
12716 - SMP: This change adds a new internal interfaces and fixes a problem
12718 is sched_cpu_pause(tcb). This function will pause a CPU if the task
12719 associated with 'tcb' is running on that CPU. This allows a different
12721 the other CPU is resumed, those modifications can safely take place.
12726 In all three cases the solutions is basically the same: (1) Call
12727 sched_cpu_pause(tcb) to pause the CPU on which the task is running,
12730 - SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting
12731 for g_cpu_irqlock with interrupts interrupts and CPU0 is waiting for
12733 - SMP: Enforce this rule: Tasks which are normally restored when
12734 sched_unlock() is called must remain pending (1) if we are in a
12735 critical section, i.e., g_cpu_irqlock is locked , or (2) other CPUs
12736 still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In
12742 - AT24XX EEPROM MTD driver: Added EEPROM timeout. Fromo Aleksandr
12744 - fs/procfs: Fix procfs status for SMP case.
12748 - Fonts: Correct some default font IDs. From Pierre-Noel Bouteville.

12754 - syslog: Fixes required for file syslog output. From Max Kriegleder.
12755 - SPI configuration: Fix Kconfig warning. This change moves the
12759 if support for the driver is enabled prevents us from defining these
12763 - drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call.
12765 is non-standard, non-portable, and cannot be supported. Instead, add
12768 - All timer lower half drivers. Port Sebastien's changes to all other
12770 - USB MSC Device: Fix length of mode6 sense reply packet. From
12772 - USB Composite Host: Fix end offset in usbhost_copyinterface(). From
12774 - USB CDC/ACM Host: Add CDC_SUBCLASS_ACM and CDC_PROTO_ATM to
12776 - SSD1306: Fix errors in SPI mode configuration. From Gong Darcy.

12778 initialized with correct functions if CONFIG_SERIAL_DMA is selected.
12782 - drivers/net/tun.c: Fix bug in TUN interface driver. From Max Nekludov.
12784 * ARMv7-A:
12786 - ARMv7-A SMP: Add SMP logic to signal handling.
12788 * ARMv7-M:
12790 - ARMv7-M: Fix double allocation of MPU region in mmu.h.
12792 * ARMv7-R:
12794 - ARMv7-R: Fix compilation error. This change fixes compilation errors
12795 on MPU support for ARMv7-R. From Heesub Shin.
12796 - ARMv7-R: fix invalid drbar handling. In ARMv7-R, [31:5] bits of DRBAR
12797 is physical base address and other bits are reserved and SBZ. Thus,
12798 there is no point in passing other than the base address. From Heesub
12800 - ARMv7-R: Remove the redundant update on SCTLR. mpu_control() is
12803 - ARMv7-R: Add new Kconfig entries for D/I-cache. Unlike in ARMv7-A/M,
12805 in ARMv7-R. This change adds those missing Kconfig entries. Actual
12808 - ARMv7-R: Add cache handling functions. This change adds functions for
12809 enabling and disabling d/i-caches which were missing for ARMv7-R.
12811 - ARMv7-R: Fix typo in mpu support. s/ARMV7M/ARMV7R/g. From Heesub Shin.
12812 - ARMv7-R: Fix CPSR corruption after exception handling. A sporadic
12819 invalid value at power-on-reset. As it is not initialized at boot, the
12822 - ARMv7-R: Fix to restore the Thumb flag in CPSR. Thumb flag in CPSR is
12828 - SAM3/4 UDP: Add delay between setting and clearing the endpoint RESET
12832 endpoint is not being reset, the Data Toggle (DTGLE) bit will not to
12833 be cleared which will cause the next transaction to fail if DTGLE is
12834 1. If that happens the host will time-out and reset the bus. Adding
12837 - SAM3/4: Remove unused 'halted' flag from UDP driver. From Wolfgang
12839 - SAM3/4: Remove 'stalled' flag from the UDP driver. This flag is not
12845 - SAM4S Xplained Pro: Configuration uses old, improper timer interface.
12851 - SAMv7 USBDEVHS: A problem occurred with the SAMV7 USBDEVHS driver if
12852 the USB cable is unplugged while a large amount of data is send over
12853 an IN endpoint using DMA. If the USB cable is plugged in again after a
12854 few seconds it is not possible to send data over this IN endpoint
12856 because if the USB cable is unplugged while an DMA transfer is in
12857 flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL
12858 is left in an undefined state. The problem was fixed the problem by
12861 - SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to
12862 CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node
12863 acknowledges the message sent. This will also occur if the device is
12864 not connected to the can-bus. The CAN-Standard declares, that the Chip
12865 has to retry a given message as long as it is not sent successfully
12866 (or it is not cancelled by the application). Every time the chip tries

15170 - TCP Networking: Correct some issues that prevent TCP from working
15171 correctly when both IPv4 and IPv6 are enabled.
15172 - TCP Networking: TCP disconnection callbacks are not retained in a
15173 list. This will support multiple callbacks per lower-level TCP
15174 connection structure. That is necessary for the cae where a socket is
15175 dup'ed and shares the same lower-level connection structure. NOTE:
15177 is dup'ed.
15178 - TCP Networking: Start the network monitor for a socket when a TCP
15179 socket is dup'ed.

15184 should be informed of the closure. That latter requirement is not
15186 - TCP Networking: Fix a race condition. The accept() operation is
15187 performed with the network locked. However, the network is unlocked
15188 BEFORE the connected state is set. Therefore, a context switch may

16512 all recent STM32 chips reading either RTC_SSR or RTC_TR is supposed
16513 to lock the values in the higher-order calendar shadow registers
16514 until RTC_DR is read. However many old chips have in their errata
16518 reading the RTC_SSR register. This happens if the read operation is

16553 lock the values in the higher-order calendar shadow registers until
16554 RTC_DR is read. Change the register read ordering to match this and
16556 any L4 errata, lets for once assume ST's silicon works as it is

17094 - configs: CONFIG_MAX_TASKS must be a power of 2.
17095 - SMP: Introduce a new global IRQ clearing logic and tasklist
17099 critical section even nxsem_wait() is still not in blocked state.

17109 sched_cpu_select() during HTTP streaming aging test on LC823450-XGEVK.
17116 - SMP: Fix this_task() to be an atomic operation. In the previous
17118 macro current_task(this_cpu()). However, I found that this is not
17122 this_task()in sched_thistask.c which is newly introduced. From
17124 - SMP: Implements a global scheduler lock capability as part of SMP
17126 or access to the TCB of the currently running task. This is
17128 is, itself, a non-atomic operation. This global scheduler lock
17130 - SMP: Extend the last global lock change to work with the
17131 LC823450-XGEVK which does not support the atomic fetch add but
17134 calculation is atomic.
17135 - SMP: Fix a infinite recursion problems that a recent changes
17136 introduced into the i.MX6 SMP implementation. This is not seen
17137 with the LC823450 because you can disable inter-processor interrupts
17138 in that architecture; but you cannot in the ARMv7-A/GIC architecture.
17139 - SMP: Remove SMP related logic in sig_dispatch.c. This change
17140 prevents from a deadlock in up_schedulesigaction.c where inter-CPU
17141 signal handling is actually implemented. arch/arm/src/armv7-m: Fix
17143 for SMP was incorrect. Thus, for example, if an inter-CPU signal
17145 change fixes the issues and works for both inter-CPU signal handling
17147 - Tasking: Add nxtask_create(). Kthread_create() and nxtask_create()
17152 - Tasking: Threads started by board bring-up logic should be kernel

17156 - Semaphore Usage: Added ECANCELED condition to DEBUGASSERT's
17159 - errno: Add new internal OS function nxsched_setaffinity() that is
17161 errno value. All usage of sched_setaffinity() within the OS is
17163 - errno: Internal functions sched_reprioritize() and
17166 - errno: Add new internal OS function nxsched_getscheduler() that is
17168 errno value. All usage of sched_getscheduler() within the OS is

17172 errno value. All usage of sched_setparam() within the OS is
17174 - errno: Add new internal OS function nxsched_getparam() that is
17178 usage of sched_getparam() within the OS is replaced with
17180 - errno: wd_start() is an internal OS function and should not set the
17182 verify if return value is used and if so if the errno value is
17184 - errno: Fix several inappropriate accesses to get_errno() that were
17185 missed in previous changes (some going back to nuttx-7.23). Add new
17190 - errno: binfmt/, configs/, graphics/, libc/, mm/, net/, sched/: OS
17193 - drivers/, fs/ and libc/: OS references to the errno variable should
17198 - FAT: CONFIG_FAT_MAXFNAME may not exceed NAME_MAX (CONFIG_NAME_MAX)
17199 - NFS: Correctly infer file type. The file type is in struct
17202 - NFS: Fix buffer corruption. In case multiple read requests to the
17204 nfs_read() might write behind the end of said buffer. This is fixed
17206 - VFS: reopen() should return NULL when oflags is less than 0, not
17207 equal to 0. Because negative value is returned on failure of
17210 - ProcFS: Fix an error in a common function that manages read data.
17211 - drivers/mmcsd: Respect SDIO_CAPS_DMABEFOREWRITE on CMD25. From

17257 - UDP: Remove some conditional logic that was true if there is only a
17258 single network device, but not true in the multi-device context.
17259 - UDP: In sendto(), return EHOSTUNREACH if the network is down.
17263 - drivers/pipes: In poll logic, fix off-by-one error in calculation
17264 of bytes in the buffer. Buffer calculation in pipe poll setup is
17265 off-by-one when read index is larger than write index. This causes

17705 - STM32 SDIO: Added internal pull-up option for SDIO pins. From Alan
17707 - STM32 F2/F4 ADC: Added Vbat measurement to ADC driver for
17710 channel first. For Vbat channel the ioctl cmd is
17713 Moreover, since Vbat input contains a built-in voltage divider, it
17714 is highly suggested to disable Vbat input channel after measurement
17715 is done in order to prevent battery drain through the divider. From
17717 - STM32, STM32L4 1WIRE: Added one bit read and write to 1-wire
17718 interface. This is needed for devices that require single bit
17719 timeslot generation and for 1-Wire search algorithm triplets. From

17780 - configs/tms570ls31x-usb-kit: Added support for the TI Hercules
17785 - CC3200: Remove all support for the CC3200. This was a port that was
17786 started but never completed. What good is partial CC3200 support
17791 - EEPROM: Implements an EEPROM driver in compliance with MTD driver
17793 supports only two functionalities - read bytes(multiple of 4) and
17795 - FLASH: Implemented Flash CONFIG_MTD_BYTE_WRITE for TM4c1294.
17798 - Serial: Added TERMIOS IOCTL support to the Tiva serial driver.
17803 - CC3200-Launchpad: Remove all support for the CC3200-Launchpad.
17804 This was a port that was started but never completed. What good is
17805 partial CC3200-Launchpad board support with no wireless support?.
17809 - libs/: Moved all of the libraries under a common directory called
17812 - libs/libc/time: Added an implementation of clock().
17813 - libs/libc/lzf: Added a modified version of Marc Alexander Lehmann's
17815 - libs/libc/unistd: Initial, minimal implementation of sysconf().

17830 - tools/nxstyle.c: Added check for blank lines before and after single
17832 - tools/sethost.sh: Added support for macOS.
17833 - tools/uncrustify.cfg: An initial cut at an uncrustify C formatting
17839 - Makefile: Added support for nconfig frontend for 'make nconfig'.
17841 - configs/: Added definition of strip to many Make.defs files.
17842 - staging/: Remove fixed lib/ subdirectory and its content. Replace
17843 with new directory called staging/ that is created dynamically when
17844 building and removed when 'make clean' is done. This both improves
17846 - tools/: Move all build-related files (except the top-level Makefile)
17847 into the tools/ sub-directory. This really cleans up the top-level
17852 - apps/nshlib: Added the mkfatfs -r option which can be used to
17858 - apps/examples/adxl372_test and lxm330spi_test: Added ADXL372 and

17873 - apps/examples/nxdemo: Added nxdemo application From Alan Carvalho
17875 - apps/examples/powerled: Added arch initialization.
17876 - apps/examples/uavcan: Removed because apps/canutils/libuavcan is no
17881 - apps/system/lzf: Added the test case from Marc Alexander Lehmann's
17883 - apps/system/embedlog: Support for embedlog data loggin package from
17885 - apps/system/zmodem: Added an option to enable hardware flow control
17887 - apps/system/zmodem: Call tcflush() before closing the serial port.
17888 This is necessary because that close operation may hang if hardware
17889 flow control is enabled. Consider this scenario: After the host
17891 completes, and tries to close the serial port. But if there is
17893 the buffered Tx data since there is no where it can go. tcflush()
17895 There is additional logic in nuttx/drivers/serial needed to work
17900 - apps/canutils/libuavcan. Removed! libuavcan has not built for a
17901 year or so. The basic problem is that as NuttX advances, the old
17903 the portable POSIX OS interface. No one is maintaining the port so
17904 there is no alternative but to remove it.
17908 - apps/netutils/tftpc: Modified the TFTP client functions to use a
17910 write to arbitrary destination (in my case, a MTD device - for
17921 - apps/wireless/bluetooth/btsak: Added a Bluetooth debug tool.
17929 - sched/sched: Fix a deadlock in SMP mode. Two months ago, I
17932 audio streaming aging test with lc823450-xgevk. However, I found a
17940 - sched/sched: Change ordering of round-robin time slice check
17951 - fs/fat: In fs_stat(), when stat'ing the root directory, avoid
17953 calculation is bogus (but not harmful) because the root directory
17955 - fs/fat: Avoid calculating the bogus directory entry address for
17959 - fs/mount: Fix wrong size reported by df -h. Reason is that size
17960 in bytes is calculated always on uint32_t types and cards bigger
17961 than 4GB will overflow uint32_t type. Solution is to use uint64_t
17963 - fs/smartfs: Fix a hardfault in SmartFS. Problem occurred when
17966 - fs/vfs: Fix negative errno set in fs_open.c From Michal Lyszczek.
17967 - drivers/mtd: Fixed a W25 driver w25_cacheflush sector bug. From
17969 - drivers/mtd: mtdconfig_register() returned OK instead of -ENOMEM on
17974 - drivers/lcd/ft80x: ACTIVE host command appears to be formatted
17976 be big-ending, BCD. Fix some compile issues when debug features
17978 - drivers/lcd/ft80x: Fix a typo that caused the driver to fail to
17980 - Review all board implementations of board_lcd_initialize(). The
17981 NuttX convention is that all internal functions that return errors
17982 as an 'int' must return a negated errno value on failure and a non-
17986 non-negative.
17990 - net/tcp: Fixed problem with send() return value when using
17992 - net/sixlowpan: Fix a nasty, byte-ordering/endian-ness problem.
17995 - net/sixlowpan: Preserve big-endian (network order) when
17997 - net/sixlowpan: TCP send should have PSH and ACK flags set when
18000 - net/udp: Fix several issues using connected UDP sockets: sendto()
18002 connect UDP sockets instead. recvfrom() is no longer necessary.
18009 - net/udp: Resolve race condition in connection-less UDP sockets with
18010 read-ahead buffering. In connection-mode UDP sockets, a remote
18011 address is retained in the UDP connection structure. This
18013 recv() will be accepted. This same mechanism is used for
18014 connection-less UDP sendto: A temporary remote address is written
18016 That address persists until the next recvfrom() when it is reset to
18017 accept any address. When UDP read-ahead buffering is enabled,
18019 in the connection structure for some time. This can cause read-
18021 between when he remote address is reset (i.e., immediately after the
18022 sendto() completes) is not a solution, that does not eliminate the
18025 is in connection mode or if it is connection-less. This change
18027 connection is always ignored if the UDP socket is not in connection-
18028 mode. No for connection-mode sockets, that remote address behaves as
18029 before. But for connection-less sockets, it is only used by sendto().
18033 - drivers/wiresless/ieee80211: Correct some initialization problems
18035 - drivers/ieee802154/xbee: Added a timeout to send logic to handle
18041 - Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and
18042 debug wrappers -- does not return a value. Rename _vsyslog to
18044 return value is required.
18045 - drivers/leds: Fixes RGB LED issues caused by uninitialized memory
18049 - drivers/sensors/lis2dh: Clear INT1 at SNIOC_WRITE_INT1THRESHOLD
18051 - drivers/sensors/sht21: Changed I2C_TRANSFER return value so that
18054 - drivers/serial: Per Matias Edlund: I recently used the tcflush
18055 function and found that it failed with ENOTTY. The reason is that
18060 - drivers/serial: Added a timeout to uart_tcdrain(). Even if
18061 tcflush() is used to discard buffered data, the close() can still
18062 hang if (a) hardware flow control is enabled, (b) CTS == 1, and
18063 (c) there is data stuck in the hardware Tx FIFO. tcflush() does
18065 This is a workaround for that.
18066 - drivers/sensors: Fix APDS9960 work queue BUG found by Kyle Lei.
18071 - arch/sim: Various fixes necessary to build the simulator under
18074 * ARMv7-R:

18087 - LPC17xx USB: Freeing endpoints should be set the same allocations
18089 - LPC17xx USB: Fix loss of RX initiatives. USB bulk endpoints are
18092 immediately if the receive request queue is empty. Thus,
18097 - Kinetis USG: USB device fixes: Use correct CONFIG OTG control,
18098 Fix interrupt storm when cable is disconnected. The DM, DP state
18100 pending asynchronous resume interrupt needed to be re-armed after
18101 the suspend is in effect. This is now done in the isr. From David
18103 - Kinetis Serial: In kinetis_lowputc.c, fix esBRFA calculation
18104 effecting baudrate. Previous BRFA was not cleared and or-ed into
18108 - Kinetis Serial: In kinetis_lowputc.c, fixed parity settings.
18110 with parity is required. If left in 8 bit mode (M=0) with parity
18111 then D7 of the TX/RX register becomes parity bit. Hence what is
18112 called 9-bit or 8-bit Mode Select is a misnomer. 8 bit mode when
18113 parity is enabled is really 7 bit with parity. From David Sidrane.
18117 - configs/teensy-3.x: Remove CONFIG_USBDEV_DUALSPEED from the usbnsh
18122 - i.MX6: Bring in a few i.MX6 fixes that were committed to similar
18127 - STM32 F3: Problem: stm32f30xx hangs waiting for LSE to initialize.
18128 Reason for hang is that operation of setting LSE_ON does not take
18129 effect because there is no clock on PWR peripheral. This is
18134 - STM32 and STM32 L4 1WIRE: In 1wire driver, do not write useless
18136 - STM32 HRTIM: Fixed capture_get function,. From raiden00pl.
18137 - STM32 F3 ADC: Fixed bug in RCC reset logic that resets ADC1
18140 - STM32 Ethernet: In case of PHY failure, usually because of the
18145 if the Ethernet block is unable to start. From Sebastien Lorquet.
18146 - STM32 F7 SDMMC: Added support for the second SDMMC device. The
18147 second SDMMC device was already supported but the clock was never
18149 - STM32 Serial: Fix UART glitch when lowputc is enabled. From
18151 - STM32 USB: Skip recipient check for descriptor related
18156 - Tiva ADC: Fix compilation errors on Tiva ADC code when ADC is
18158 - Tiva Serial: Allow building of Tiva platform with no serial

18180 - LibTargets.mk, tools/Config.mk: Drop executable bit on installed
18186 - apps/examples/ft80x: Fix some size calculations. Added option to
18190 - apps/examples/ft80x: Text is handled by the coprocessor and, hence,
18192 - apps/examples/ft80x: Fix some errors in co-processor demos. Correct
18194 - apps/examples/nsh and posix_spawn: Must not call exec_setsymtab()
18195 directly. That is a non-POSIX internal OS interface.
18196 - apps/examples/ostest: Do not call AIO test without
18198 - apps/examples/smps: Fix typos in Kconfig. All power, voltage,
18201 - apps/examples/smps: Fixes in some printf and in Kconfig From
18203 - apps/system/zmodem: Fix Makefile.host. It was broken when zmodem.h
18209 - apps/system: Applications should use the standard clock() interface,
18211 - apps/system/stackmonitor: Fix comparison between pointer and zero
18216 - apps/netutils/netlib: Various fixes needed to get a clean netlib
18221 - apps/wireless: Applications should use the standard clock()
18224 NuttX-7.26 Release Notes

18248 - Initialization: Add option to mount block device for
18250 - clock(): clock_systimer() is no longer a system interface. It has
18253 core. This is necessary because it calls the (now) internal OS
18254 function clock_systimer(). clock() is now accessed only via a
18256 - clock Utilities: Move clock_timespec_[add|subtract] to
18258 - Binary Loader: Add binfmt_initialize(). All binary formats are

18278 - Signals: Update the signal default action logic to support
18281 SIG_DFL it is replacing the default action. From Gregory Nutt.
18282 - Signals: Default Signal Actions. Change some types to

20402 Ethernet is completely re-initialized when an error occurs by means of
20403 taking the interface down and back up but the PHY is _not_
20404 renegotiated for that case because that is very time consuming and an
20405 error in the Ethernet is no reflection on the state of the PHY

23175 - apps/graphics/twm4nx. This release introduces Twm4Nx. Twm4Nx is a
23177 1.0.10 to NuttX NX windows server. No, a port is not the right
23178 word. It is are-design of TWM from the inside out to work with the
23180 legacy. But Twm4Nx is more a homage to TWM than a port of TWM.
23184 icon management, user-defined macro functions, click-to-type and
23185 pointer-driven keyboard focus, graphic contexts, and user-specified
23188 Twm4Nx, on the other hand is based on the NuttX NX server which
23193 Twm4Nx is greatly stripped down and targeted on small embedded systems
23194 with minimal resources. For example, no assumption is made about the
23195 availability of a file system; no .twmrc file is used.
23197 The state of the "port" is available in
23198 apps/graphics/twm4mx/README.txt. To summarize: The port is fully
23200 missing critical feature is built-in touchscreen calibration.

23256 side effect is that this changed to order of initialization of
23260 - pthread Stack Attribute: Fixed pthread_attr_get/setstacksize
23262 - Signals: The abnormal termination signal handler was just calling
23263 exit() conditionally when, for example, Ctrl-C is sent to a task.
23265 points: If cancellation is disabled, then the abnormal termination
23266 logic must wait for cancellation to be re-enabled; If cancellation
23267 is deferred then the abnormal termination logic may have to wait
23270 - Syscall: Added support for munmap() syscall. From Joao Matos.
23271 - Syscall: Fix a warning due to inconsistencies in return type in

23280 block assignment, the second must be root[1]. From YanLin Zhu.
23284 - getsockname(): Fix addrlen check in socket debug features.
23287 This causes also a compilation failure if the code is compiled
23288 with CONFIG_DEBUG_FEATURES and with -Werror flag set. From Jukka
23290 - Network Locking: net_lock() and net_restorelock() now return a
23291 value. That values is the standard zero on success; negated errn
23292 value on failure. This return value is only needed for
23293 -ECANCELED. That cancellation indication needs to ripple all the
23297 at higher levels. That is required too. From Gregory Nutt.

23316 for all cases ... EXCEPT ONE: When the window is resized to a
23319 - NxTK: Fix an error in handling mouse events for framed windows.
23321 The is only for NX windows, but the outside-the-side positions were
23323 - NxTK: Refuse to open a toolbar of height zero or less. From

23336 - Power: Fix build for battery gauge From Tom Kopriva.
23337 - Syslog: In syslog buffered mode, avoid IOB alloc lock-up with
23345 - USB CDC/ACM Device: This fixes a problem where the host sent a
23350 so that the composite driver checks not only if this is a
23351 "standard" message but if it is also directed to the device.
23352 Otherwise, the handling is delegated to the children of the
23354 - USB HID: The usbhid_descriptor_s struct defined in hid.h included
23355 some optional fields that should not be hard-defined as part of
23357 included in the descriptor, but that is not properly represented.
23359 with an optional descriptor so it is safe to remove. From Matias N.
23360 - USB MSC Device: Correct typo "const const" to "const".
23364 - Zerocross Driver: Fix some errors when debug assertions are
23366 - User Leds: Fix ledset validity check in ULEDIOC_SETALL ioctl.
23371 - All board interfaces (those starting with board_) must be defined
23372 in board-specific logic. Otherwise, they cannot be customized for
23374 interface was defined in architecture-specific logic that only
23375 called up_systemreset(). That is useless! This change removes
23376 the board_reset() implementation from the architecture-specific
23377 code and re-implements it in the src/ directory of each board that
23378 has CONFIG_BOARDCTL_RESET enabled. That is the correct functional
23380 - Start-up: Remove dependency on CONFIG_ARCH_FPU for inclusion of
23382 - Architecture initialization: up_initialize() needs to know about
23387 - PIC32MZ GPIO: Corrects the gpioirq when mismatch mode is

24493 NuttX-8.1 Release Notes
24494 ------------------------
24497 and is available for download from the Bitbucket.org website. Note
24498 that release consists of two tarballs: nuttx-8.1.tar.gz and
24499 apps-8.1.tar.gz. These are available from:
24504 Both may be needed (see the top-level nuttx/README.txt file for build
24507 The major release version number is only incremented when there is a major
24508 change to the OS that makes it more-or-less incompatible with preceding
24511 in nuttx-7.31. That directory has been renamed boards/ and now has a
24515 board/ - Holds all board-related information
24516 board/<arch> - Holds board-related information for all boards that use
24517 the same CPU architecture. For example, all ARM-based boards will be
24519 board/<arch>/<chip> - Holds board-related information for all boards
24520 that use the same MCU chip family. For example, all STM32-based
24522 board/<arch>/<chip>/<board> - Holds board-related information for a
24523 specific board. This is analogous to the configs/<board> directory in
24524 nuttx-7.31. So, for example, the STM32F4-Discovery board support that
24527 boards/<arch>/<chip>/<board>/<configs> - All configurations for a
24529 subdirectory. So, continuing the example, the STM32F4-Discovery NSH
24538 This re-organization is the work of Alin Jerpelea. Not only did Alin do
24539 this major directory re-organization, but he ran the code standard
24545 stick with it until it is finished. Kudos!
24547 A more constrained re-organization of the drivers/ directory was also
24550 for a new set of RF-related drivers.

24737 the WiFi is minimal so far but functionality is proven. I'm
24739 from a DMA data checksum failure, but that is an issue that can be
24741 interfaces fleshed out and the hardware proven so it can go for pre-
24742 production build. I _think_ there's only Bluetooth and USB-device

24957 32-bits to allow more flags. From Nathan Hartman.
24961 - Export Build: Export all variables/files to support architecture
24963 - Application Export: This change too build tools allows to export
24964 built-in applications registry into temporarily created directory
24965 where export archive content is prepared. If the Makefile in apps/
24966 directory does not define export: target then error is print but
24968 print warning but there is no way instruct apps make to not print
24970 - boards/Board.mk: Add support to pass dependency paths. From
24975 - libs/libc/libc.csv: Add some missing C library functions. From
24977 - libs/libc/libc.csv: Add ioctl() to fs_ioctl() wrapper for varidic
24979 - libs/libc/builtin/: Moves shared built-in information out of
24981 with applications. This should permit built-in application in the
24984 - libs/libc/dirent/: Added alphasort() implementation, scandir()
24988 - libs/libc/grp/: Added stubbed implementations of getgrgid,
24992 The intend is not to provide meaningful new features, but to ease
24994 - libs/libc/machine/arm/armv7-m/: Add Cortex M4F machine optimized
24996 - libs/libc/pwd/: Added stubbed implementations. Added stubbed
25000 was 'root' with uid 0. The intend is not to provide meaningful
25003 - libs/libc/pwd and libs/libc/grp/: Modify to get user/group data
25006 - libs/libc/stdio/: Add support for the size_t integer qualifier 'z'
25007 to the printf family. This is kind of tricky due the variety of
25009 - libs/libc/unistd.h: Added stubbed implementations of setuid() and
25013 respectively. The intent is not to provide meaningful new features,
25016 - libs/libc/unistd/: Add getuid() and getgid() stubs to match

25026 - NuttX provides lists of available syscalls and library functions and
25034 is generated in form libsymtab.a which can be reused by application
25038 modes but tested only flat no-MMU build. The basic assumption is
25039 that this library and libraries providing syscall stubs and C-
25040 library functions are available in user-space context and initial
25044 I am not sure if really support in MMU mode. It is highly probable
25046 functionality is optional (should not cause troubles in any mode if
25047 disabled) and main purpose is to lower memory overhead when more
25055 - tools/: Change preferred argument of configurations tools to use
25056 ':' as the delimiter between <board-name> and <config-name>. This
25057 is to emphasize that this is not a path; it is configuration
25058 specification. The legacy '/' delimiter is still supported but
25061 delimiter. Update all configuration-related tools to accept ':'
25066 - Makefile: Added support for application-specific export target.
25068 - apps/builtins: Move apps/builtins/builtin_forindex.c to
25069 nuttx/libs/libc/builtin since it is required by kernel logic as
25076 - apps/examples/uid: Demo used to verify PASSWD and GROUP interfaces.
25078 - apps/examples/webserver/: Initialilze network and run forever only
25079 if not built-in app. Infer from CONFIG_NSH_BUILTIN_APPS if we are a
25080 NSH built-in app or not. If built-in app (CONFIG_NSH_BUILTIN_APPS
25081 defined) then we assume network is initialized prior to webserver
25083 (CONFIG_NSH_BUILTIN_APPS is undefined) then behavior is unchanged:

25133 group ID. That is incorrect. Than naming is reserved for use with
25135 that it is clearer that these refer to NuttX task group IDs, and not
25137 - Task Termination: nxtask_signalparent() in task_exithook.c may
25139 tg_ppid field is use only to remember the parent tasks ID so that it
25143 tg_ppid. That would be okay, except that the SIGCHLD is only sent
25144 when the last member of the group terminates. That is incorrect;
25149 - sched_get_rr_interval(): sched_get_rr_interval() should return
25150 {0,0} if round-robin scheduling is not selected for the task. From
25152 - SMP Type Collision: The non-standard, non-portable type cpu_set_t
25156 occurred. cpu_set_t has an equivalent, non-standard, non-portable
25158 non-standard type to be defined. Who am I to stand in the way of
25160 that cpu_set_t is typed (as a uint8_t) even if CONFIG_SMP is not
25162 - Binary Loader: Change some debug macros from berr() to binfo()
25163 when dumping module data. The report of problems is important

25210 - RNDIS: Fix issue with DEBUGASSERT when using composite device and
25215 - wireless network devices: Attach radio to d_buf before registering
25216 device to handle forwarding case. When CONFIG_NET_IPFORWARD is
25217 enabled, and CONFIG_NET_6LOWPAN is being used, a packet that
25220 will fire. The underlying "radio" in this case is the
25222 because the buffer is normally attached in the periodic txpoll
25225 - IEEE 802.15.4 MAC: Fixes issues with extended address. 1) Extended
25226 address should be read-only. 2) Extended address should be placed
25227 in frame in "reverse-canonical" order. The extended address is a
25228 read-only attribute and thus an attempt to write the extended
25231 bring-up time to the radio layer. The MAC layer now pulls in the
25232 extended address from the radio any time the MAC is reset. The
25233 extended address is also supposed to be sent in the frame in
25234 reverse-canonical order. This is very confusing in the standard and
25240 written in reverse-canonical form, meaning the OUI comes last, not
25242 - IEEE 802.15.4 MAC: Frame Version should have been 1, but was being
25244 to build to indicate what is noted in the menu for

25263 occasionally the XBee is completely locked up and the XBee has to
25267 attempts, the XBee is reset. From Anthony Merlino.
25268 - Xbee: Cancel query timeout upon receiving the expected response.
25271 - Xbee: Detect lockup and reset XBee in xbee_req_data From Anthony
25273 - Xbee: Fixes one instance of the use of IOBUSER_WIRELESS_MAC802154
25276 is always available when IEEE 802.15.4 support is enable. From
25281 - pipes: Use inode reference counter instead of device reference
25283 reference counter d_refs is not increased. If I close any of the
25286 change uses the inode reference counter, which is properly

25289 support is enabled. From Augusto Fraga Giachero.
25290 - GPIO Lower Half: Remove limitation when pintype >
25295 - Classic ARM7/ARM9: When performing stability test, the application
25297 register R1 has been changed, and its value is the same as register
25298 CPSR. In up_fullcontextrestore.S, the restoration of R0 and R1 is
25301 Fix is to use a single ldmia to restore R0, R1, and return via R15.

25317 supported only by ARMv7-M). In the normal course of things,
25320 be shared between interrupt level and non-interrupt level logic.
25326 disable interrupts, then the answer is that we must disable ONLY the
25327 "normal interrupts". That is because we cannot disable SVCALL
25336 - ARMv7-M Priorities: In the 'normal' case, the priority of the
25340 interrupt response. Fix is to raise the priority of the high
25346 - i.MXRT ENC: Fix some errors in register bit definitions. Noted by

25383 transactions can take quite a bit, so a fixed timeout is not a
25390 - Kinetis I2C: i2c transfer ensure correct result returned.
25397 - LPC17xx/40xx CAN: If BOARD_CCLKSEL_DIVIDER is not equal to 1 on
25398 LPC178x or LPC40xx then base clock rate is calculated incorrectly
25399 because CCLK frequency does not correspond to PLL0 clock which is
25400 used for PCLK. This is partially workaround solution. It would

25522 Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP,
25523 TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently
25524 supported by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL
