1506 the second pass builds the NuttX executable more-or-less as
1511 CONFIG_EXAMPLE. CONFIG_EXAMPLE used to identify the sub-directory
1513 application to be built. That made it awkward to configure to
1515 directory. CONFIG_APP_DIR is more general; it can be used to
1516 refer to any directory containing the application to be built.
1519 you will need to make a couple of changes:
1521 - Replace all occurrences of CONFIG_EXAMPLE=foobar with
1524 - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with
1526 - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT)
1528 - Check any other occurrences of CONFIG_EXAMPLE.

1888 functionality has been separated from NuttX application-related
1891 * nuttx-6.0.tar.gz, and
1892 * apps-6.0.tar.gz
1894 The purpose of this separation is both to better organize and
1895 modularize the NuttX source tree, but also to provide better support
1896 for incorporation of end-user applications with NuttX.
1898 The incompatibility results from the changes to the board configuration
1899 logic needed to supported the separable application. The major
1900 changes to the configuration include:
1902 * CONFIG_APPS_DIR - This should not be set. The default is
1904 product-specific application directory in some different location.
1906 * appconfig - Each board configuration now requires a new file
1910 In addition to this major reorganization in the directory structure,
1911 this release also includes some important extensions to existing

5770 M4 architectures: To enable an interrupt on the Cortex-M3/4 CPU,
5771 you need to set a bit in the ISER register. To disable the
5772 interrupt, you need to set a bit in the ICER register. Existing
5773 logic was trying to disable interrupts by clearing the bit in the
5774 ISER register. That will not work; writing a '0' to the ISER

8111 apps-7.8.tar.gz. Both may be needed (see the top-level nuttx/README.txt
8114 This release is primarily a bugfix release for the NuttX-7.7 version that
8116 modifications in the NuttX networking to accommodate support for IPv6. This
8117 release follows close behind NuttX-7.7 in order to correct some the problems
8119 small number of new features and bug fixes unrelated to NuttX networking.
8125 - Tickless Mode: added limit of maximum delay that can be request
8132 - VFS Unlink: Add an unlink method to both the character and block
8134 unlinked and there are no open references to the driver, then the
8138 - Pipes and FIFOs: Implement the unlink method. If the pipe/FIFO is
8140 open references to the driver are closed, all of the driver
8142 - Added an option to use the syslog'ing device as the system console.
8143 This option enables a low-level, write-only console device at
8144 /dev/console (similar to the low-level UART console device). From
8145 Pierre-noel Bouteville.
8149 - RAM/ROM disk: Add logic to dispose of the driver and RAM buffer
8150 when the RAM disk has been unlinked and all open references to the
8151 RAM disk have been closed. Add new parameters to romdisk() to
8152 specify what should be done with the RAM/ROM buffer in this case --
8153 Should it be freed or not? Changed all calls to ramdisk() to use
8158 - Add support for local, Unix domain sockets. Support included for
8160 - UDP enhancement: Add UDP read-ahead support. In addition to

8292 standard post-pended prefix value, rather than the full 128-bit
8296 implemented but present in this release. They are not likely to be
8300 realization of Unix-style user processes in NuttX. There is more to
8313 - Work Queues: Fix a backward calculation when determining the time
8314 to the next interesting event. . From Liio Chen via the PX4
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
8328 wait for TCP read-ahead buffering space to be available. It should
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
8339 style and also can lead to a deadlock condition.
8340 - ARP response waiting: Fixes another CONFIG_NET_NOINTS issue. When
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
8346 socket as 'connected' got moved to BEFORE the point where the check
8349 it would fail to connect. But then if try again, it would connect
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
8359 - Pipes and FIFOs: Fix a race condition between FIFO buffer operations
8361 are used to support Unix domain, datagram sockets. The default
8364 in the FIFO will be lost. Some like UDP read-ahead is needed: The
8365 buffered data in the FIFO needs to be retained until the reader gets
8366 a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to
8370 - RAMTRON: Table of parts is not terminated properly if
8376 - Removed all occurrences of up_maskack_irq() that disables interrupts
8379 unconditionally re-enables interrupts with the interrupt exits. This
8380 interferes with the drivers ability to control the interrupt state.
8382 impossible to test.
8386 - ARMv7-A and ARMv7-M memcpy(): Optimized ARM assembly language
8387 memcpy's were not returning a value in R0 they are required to do.
8389 - ARMv7-A interrupt handler should not automatically re-enable interrupts
8390 on interrupt return. That interferes with the driver's ability to
8391 manage interrupts. Analogous change made to all other architectures
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
8424 NuttX-7.9
8425 ---------
8429 that release consists of two tarballs: nuttx-7.9.tar.gz and
8430 apps-7.9.tar.gz. Both may be needed (see the top-level nuttx/README.txt
8437 - Assertions: Add support for dumping board-specific information on
8439 - boardctl(): : Add a new non-standard OS interface called boardctl().
8440 This is similar to a driver IOCTL call. But this is an IOCTL call
8442 all of the ad hoc OS interfaces that are current used to perform
8445 these rogue interface in to at least a single crazy call.
8449 - Line Joins: Line drawing graphic functions now take an argument that

8575 - gettimeofday(): This function is no longer a core OS interface. It
8577 - settimeofday(): Added. gettimeofday has been deprecated in POSIX
8578 2008. settimeofday() was never part of POSIX, but I decided to add
8579 it to libc as well just for symmetry.
8580 - Day-of-Week: Add CONFIG_TIME_EXTENDED to support the last 3 members
8583 - sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New

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.

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.
8612 Ported to NuttX by Darcy Gong.
8613 - TZ database: All logic to build timezone database needed for
8617 implemented but present in this release. They are not likely to be
8621 realization of Unix-style user processes in NuttX. There is more to
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
8642 be greater than OR EQUAL TO 1000000000 for maximum value of nanoseconds
8644 - Time initialization: Fix an error in time initialization when there
8646 The call to clock_calendar2utc() was returning the time in units of
8647 seconds. The initialization logic, however, was expecting to get
8649 obviously has not significant impact to behavior in systems where
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
8660 time to 64-bit millisecond value in clock_systmer64() causes some
8661 bad times to be returned. Time was converted to milliseconds, then
8662 to configured ticks. Precision was lost in the millisecond
8663 conversion. The fix is to first convert time to a 64-bit microsecond
8664 value, then to the configured tick value. Noted by David Sidrane.
8665 - clock_systimespec(): When an RTC is used clock_systimespec() must
8666 subtract the basetime from the returned time. It needs to return
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
8682 to ensure mkfatfs operates with boards that use DMA for microSD.
8684 - FAT unmount: Fix a bug in the FAT unbind() logic. There were
8687 structures were never being added to the list of open files. So
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
8695 function otherwise the open count will only be incremented from 0 to
8696 1. This caused problems when trying to open the can bus from two
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()
8709 data structures are ready to register new network devices.
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
8723 wait loop must be inserted before writing the next block of data to
8725 - MMCSD SDIO: Fix some bad logic when file system debug is turned on:
8726 Arguments to syslog were missing so that garbage was being printed.
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
8739 write the correct value to the MPU_RASR register. From Juha Niskanen.
8743 - SAM3/4 Serial TERMIOS: A side-effect of changing serial settings
8746 changed when there are no open references to the serial device. In
8750 to receive data. In that case, the side-effect of disabling
8753 - SAM3/4 Serial: The IMR register is read-only. This means that
8754 sam_restoreints() did not actually re-enable UART interrupts
8755 (Fortunately, that function was not being used up to this point).
8756 - SAMA5 HSMCI: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift
8758 blocks in the BLOCKR register. This was sufficient to prevent DMA
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
8785 register lead to rtc_setup() call that rightfully enables the LSI
8787 rtc_resume() call does NOT start the LSI clock! The right place to
8791 IWDG, while the LSE only for the RTC (and to output the MCO1 pin).
8797 - Tiva GPIO driver needed small fixes in the configuration routines and
8798 discovered false-positive bugs in interrupt testing: interrupts are
8799 now verified to actually be working reliably. From Calvin Maguranis .
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
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
8820 double). Functions could maybe be optimized to use only first term (x)
8822 - localtime(): Inconsistent configuration name: CONFIG_LIBC_TZDIR vs
8827 - Modbus: Fix some compile problems when TCP is enabled.

9053 does not do what pthread_kill() is supposed to do. The corrected
9055 to the specific pthread and no other.
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
9064 nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support

9108 - Local Sockets: Local stream sockets had problem of double releasing
9110 pipe pair being closed in multi-client case. Solve by adding per
9111 connection instance ID to pipe names. From Jussi Kivilinna.
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
9118 callers of net_startmonitor() to assume that the connection was
9120 causing the socket to be incorrectly marked as connected. This
9122 - setsockopt() failed when setting timeouts to values less tha 100
9123 msec. That is because the timeout is limited to stops of 1
9126 net_timeval2dsec() now accepts and option to determine how it
9128 the remainder to round to the closed decisecond value, or use any
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
9134 and the TCP state is not yet correct for a connected socket. However,
9136 condition that causes worse problems when trying to connect. The fix
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
9150 - SAM3/4 Serial: When reconfigured, serial does not receive bytes

9617 - Nx Lines example: If CONFIG_NX_ANTIALIASING=y, then the nxlines
9619 than the line it drew. That eliminates edges effects due to
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
9627 Need better interlocking to assure that the threads actually do start

10223 clock_systimer() is called rather then chopping the 64-bit timer
10224 down to 32-bits. Add a new type, systime_t to represent the 32- or
10225 64-bit system timer. This eliminates clock_systimer32() and

10321 support using __flash and __memx symbols. The former indicates to
10322 compiler that this is a flash-based object. The later used with
10324 flash or in RAM. The compiler automatically makes 32-bit pointer
10326 and generates code to access either in run-time. Thus, any function
10330 AVR this allows to move all constant strings used in trace messages
10331 to flash in the instruction address space, releasing resources for

10417 someone tries to set one of the pins 8-15. The problem is that
10420 call to the I2C_WRITE buf[0] is used as address but this address is
10422 to the register in the ioexpander and not the I2C address. From
10427 - TCP/IOB: Numerous fixes, mostly relate to TCP and IOB buffering
10429 networking later to be stable in some stress testing. From Andrew

10977 - SAMV7 Tickless Mode: This is a fix to a problem in the handling of
10978 the oneshot timer. Due to a wrong assumption concerning the behavior
10982 of the timer, but this is not true. To start the time/counter a
10984 sets the counter register to zero, but the reset of the counter
10985 register is not performed instantly. According to the datasheet:
10987 value passes to zero on the next valid edge of the selected clock."
10988 Thus the counter is set to zero between 0 and USEC_PER_TICK
10990 In my fix I use the freerun count value to determine if at least one
10992 the oneshot counter is correct. I also tried to use the function
10993 up_timer_gettime to achieve this but, at least if compiled with
10999 is between 0 and USEC_PER_TICK microseconds too long. To fix this I
11001 one tick and otherwise set the remaining time to zero. By doing so

11013 be applied to the SAM3/4 oneshot time since the drivers are identical.

11085 NuttX-7.17 Release Notes
11086 ------------------------
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).

11116 - CAN: Add support for poll. From Paul Alexander Patience.
11117 - GPIO: Add support for a simple GPIO driver. It supports only pre-
11119 output operations. Interrupt events can lead to notification via a
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
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
11131 circular buffer. Move pipe() and mkpipe() to the C library, they are
11133 logic to support, configurable, smaller buffers for PTYs.
11137 - SYSLOG: Consolidated all SYSLOG logic in drivers/syslog. Added an
11140 transition to another SYSLOG output when the OS has initialialized,
11144 usable with other-than-FLAT builds.

11151 to the SYSLOG channel (Not be be confused the SYSLGO output to a
11153 - Debug features are now enabled separately from debug output.
11156 respectively. This also applies to all of the variants as well,
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
11168 only error conditions. Convert *err() to either *info() or add
11170 - _alert(): New debug macro: _alert(). This is high priority,
11171 unconditional output and is used to simplify and standardize crash
11173 - Many CONFIG_DEBUG_* options did not have matching macros defined in
11180 - Added the simulated QSPI (N25Q) flash to the simulation and extended
11181 flash simulation capabilities to run with MTD drivers based on config

11189 o Increase the allowed SPI-Frequency from 20 to 40 MHz.
11192 defined in a Kconfig file. The change renames it to
11196 (single device) to "variable peripheral selection" (multiple
11198 o Add a new Function to the interface to control the timing and
11201 the first bit, between the last bit and the de-assertion of the
11202 ChipSelect and between two ChipSelects. This is needed to tune
11204 o Add three "hw-features" for the SAMV7, which controls the behavior
11206 - force CS inactive after transfer: this forces a (short) de-
11209 - force CS active after transfer: this forces the CS to stay
11211 Btw.: this is a prerequisite to make the LASTXFER bit working
11213 - escape LASTXFER: this suppresses the LASTXFER bit at the end
11214 of the next transfer. The "escape"-Flag is reset automatically.
11217 - TWISHS: Driver improvements from Michael Spahlinger.
11218 - GPIO-Driver fixed for Open-Drain Pins:
11221 back. This is extremely important for Open-Drain Pins, which
11223 o Re-Implemented twi_reset-function and enhanced it so it can be
11225 o Glitch-Filter: Added a configuration option to enable the twi-
11226 built-in glitch filter
11227 o Added a "Single Master Mode": In EMC Testing the TWI-Bus got
11228 stuck because the TWI-Master detected a Multi-Master access (but
11234 With the above changes I2C-Bus reliability in harsh environments (eg.
11235 EMC) is greatly improved. The small change in the GPIO-Driver was

12212 1.0; and, in the case of asinl(), sometimes fails to converge (loops
12216 based on Chebyshev fitting to a good guess. The problem there's a
12217 bug in the implementation that causes the functions to blow up with
12218 x near -3.0. This patch fixes that problem. It should be noted that

12238 - Top-Level Makefiles: Fix a chicken-and-egg problem. In the menuconfig
12239 target, the context dependency was executed before kconfig-mconf. That
12240 was necessary because the link at apps/platform/board needed to be set
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
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

12640 least NuttX-7.20.
12648 - sched/semaphore: Within the OS, when a thread obtains a semaphore
12657 The fix was to have sem_post() call sem_addholder() just before
12660 - Many files: Make sure that priority inheritance is not enabled for
12663 - sched/semaphore: sem_trywait() no longer modifies the errno value
12664 UNLESS an error occurs. This allows these functions to be used
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
12668 to START_YEAR, MONTH, and DAY in sched/Kconfig.
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
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
12679 does not make any sense to send signal if it is already running and

12690 - task_restart: Make sure new task starts with pre-emption disabled and
12692 - Enter/leave Critical Sections. Major redeign to
12693 enter/leave_critical_section logic to deal with the case where
12695 rather complex spinlocks must be used to maintain the critical section
12697 - SMP Critical Sections: Fixes for the SMP case: (1) Change order for
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.
12708 differently: Locks are required to protect code. this change adds
12709 locking (via enter_critical section) to wdog expiration logic for the
12711 - SMP vfork(): Fix a race condition in the SMP case. Existing logic
12716 - SMP: This change adds a new internal interfaces and fixes a problem
12720 CPU to modify that OS data structures associated with the CPU. When
12722 The three fixes are to handle cases in the SMP configuration where one
12723 CPU does need to make modifications to TCB and data structures on a
12727 sched_cpu_pause(tcb) to pause the CPU on which the task is running,
12728 (2) perform the necessary operations, then (3) call up_cpu_resume() to
12730 - SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting
12733 - SMP: Enforce this rule: Tasks which are normally restored when
12736 still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In

12859 resetting the register SAM_USBHS_DEVDMACTRL to a known state.
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
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
12867 to resend the message an Acknowledge-Error-Interrupt is generated. At
12870 application). To prevent this Interrupt-Flooding we disable the ACKE

14016 because in sem_wait() the holder is released, but needs to remain in
14018 to sem_restorebaseprio() must be one of the last things the
14019 sem_wait() does because it can cause the task to be suspended. If in

14041 releasing the running task slot prior to reprioritization that can
14042 lead to the context switch. To faclitate this, the interface to
14043 sem_restorebaseprio needed to take the tcb from the holder prior to
14046 the additional thunking on the foreach to get from holer to
14047 holder->tcb. An alternate approach could be to leve the interface

15608 ------------------------
15612 that release consists of two tarballs: nuttx-7.23.tar.gz and
15613 apps-7.23.tar.gz. These are available from:
15618 Both may be needed (see the top-level nuttx/README.txt file for build
15625 - sem_open() should return SEM_FAILED on any failures. This is change
15628 - exec(): The non-standard interface exec() is now enshrined as a
15630 this is probably the only want to load programs in the protected
15635 of code in the user-space blob so that is they exec() is really
15641 - OS Internal Functions: Rename many OS internal functions so it is
15645 - Cancellation Points: Add new cancellation point interface,
15647 - Signals: Add logic to wake up a thread that is waiting on a signal
15649 - sigtimedwait(): Add logic to suppress the wait if there is a
15651 - clock_nanosleep(): Implement clock_nanosleep(). nanosleep() is now
15652 reduced to a libc wrapper around clock_nanosleep().
15653 - task_delete(): Do not permit user applications to delete kernel
15655 - kthread_create(): Rename kernel_thread() to kthread_create() for
15657 - boardctl(): Remove the BOARDIOC_GRAPHICS_SETUP command.

15733 pre-initialized, read-only routing table provided by the
15734 board-specific logic.
15737 packets to go to the single adaptor in all cases. So for that
15738 behavior you could add a read-only routing table to the
15739 board-specific long that contains a single entry, the default route:
15741 - Routing Tables. Added support for routing tables in files in a file
15742 system. This might be useful for customized, per-unit routing
15745 think it probably should have a small, in-memory cache of most
15747 2. Currently the delroute logic is disabled due to a problem with
15749 Therefore, it is not possible to delete entries from the routing
15752 might include a tag on each record to indicate if the record is
15753 valid or not. That would work but would add complexity to the
15755 - Routing Tables: Add support for an in-memory routing table cache in
15756 order to improve performance when the routing table is retained in a
15758 and so can eliminate some file access. Flush the in-memory cache
15760 matching an IP address is found, add the routing table entry to the
15762 - Routing Tables: Add logic to mark a route as most-recently-used in
15764 - ICMP: This change adds support for semi-standard IPPROTO_ICMP

16342 configuration, the TCP connection's 'semi-permanent' callback,
16344 in tcp_lost_connection() attempt to use that callback reference
16348 - UDP Broadcast: Fix some issues with regard to UDP broadcast
16350 - ICMP: Fix an error in the poll logic. It was assumed that the
16354 - ICMPv6: Fixes several errors preventing icmpv6_radvertise.c from
16355 being compiled. Fixes conversions to network byte order (namely
16356 vlifetime, plifetime, mtu). IPv6 source address is set to
16357 link-local IP address instead of the address in the netdev
16358 structure. This is in compliance to RFC 4861. RA didn't work on
16361 structure. This seems to make more sense than using a predefined,
16362 separate prefix from the config. From Sakari Kapanen.
16363 - ICMPV6: icmpv6_input() needs to set d_len to 0 after consuming echo

16378 dispatch). Adds a separate local variable, protosize, to keep track
16380 - 6LoWPAN: Fix an endian-ness problem in 6LoWPAN address
16382 - 6LoWPAN: The logic that extracts interface identifier from the IP
16383 address needs to be generalized to handle cases where the address is

16402 - STMPE811: Fix GPIO operation of STMPE811 driver.
16404 redefined to be the pin direction mask for `stmpe811_gpioconfig`.
16405 I decided to change register name to be STMPE811_GPIO_DIR_REG, and
16410 3. The call to `stmpe811_gpiowrite` from inside of
16411 `stmpe811_gpioconfig` leaded to deadlock.
16413 - BQ2429X: Add BATIO_OPRTN_SYSON for enabling BATFET after SYSOFF.

16493 - STM32 CAN: Lower part of STM32 CAN driver
16500 pretends to be "file like" I expect data to be read from fd the same
16501 order it is written. So I consider described behaviour to be a bug.
16504 - STM32 HRTIM: Fix pclk calculation. From Mateusz Szafoni.
16505 - STM32 HRTIM: Fix burst mode prescaler update. From Mateusz Szafoni.
16506 - STM32 (alt) I2C: Ensure proper error handling. Injecting data
16507 errors would cause the driver to continually reenter the isr with
16508 BERR an RxNE. This fix allows the error to be cleared and
16509 propagated to the waiting task. From David Sidrane.
16510 - STM32: LTDC and DMA2D drivers are not permitted to set the errno.
16511 - STM32 RTC: Workaround for potential subseconds race condition. In
16513 to lock the values in the higher-order calendar shadow registers

16551 - STM32 L4 RTC: Correct RTC_SSR and RTC_TR read ordering. In all
16552 recent STM32 chips reading either RTC_SSR or RTC_TR is supposed to
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
16558 - STM32 L4 RTC: Init mode was never exited because nested locking in
16560 - STM32 L4 RTC: Use backup register magic value instead of INITS
16561 bit. The INITS (bit 4) of RTC_ISR register cannot be used to
16565 set. Hardware also clears the bit when RTC date is set back to year
16567 - STM32 L4 RTC: Put back the SSR race condition workaround. ST has
16568 confirmed that the issue has not been fixed, and that it applies to
16569 STM32 L4 too (was not in errata sheets due to documentation bug) See
16570 discussion: https://community.st.com/thread/43710-issue-with-rtc-maximum-time-resolution .

16659 - apps/nshlib: This commit eliminates the ping and ping6 commands
16660 from NSH and replaces them with 'built-in' commands at
16662 commands violated the portable POSIX interface and, hence, had to
16663 be removed. The new system/ping and ping6 built-in commands uses
16665 sockets to implement ping.
16666 - apps/nshlib: Fix parsing of empty strings when CONFIG_NSH_CMDPARMS
16671 - All configurations that use NXIMAGE or NXHELLO must select

17105 In addition, by this change, task_exit() had to be modified so that
17109 sched_cpu_select() during HTTP streaming aging test on LC823450-XGEVK.
17113 To avoid this, I introduced tasklist protection APIs. With these
17116 - SMP: Fix this_task() to be an atomic operation. In the previous
17124 - SMP: Implements a global scheduler lock capability as part of SMP
17125 support. This allows the scheduler to be locked with no knowledge
17126 or access to the TCB of the currently running task. This is
17128 is, itself, a non-atomic operation. This global scheduler lock
17129 capability was add just to support that atomic access to the TCB.
17130 - SMP: Extend the last global lock change to work with the
17131 LC823450-XGEVK which does not support the atomic fetch add but
17135 - SMP: Fix a infinite recursion problems that a recent changes
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

17171 identical to sched_setparam() except that it does not modify the
17174 - errno: Add new internal OS function nxsched_getparam() that is
17175 identical to sched_getparam() except that it does not modify the
17176 errno value (actually, the previous value erroneously neglected to
17177 set the errno value to begin with, but this fixes both issues). All
17180 - errno: wd_start() is an internal OS function and should not set the
17181 errno value. Reviewed and updated every call to wd_start() to
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
17187 equivalent to their counterparts without the nx on front. These
17189 the OS to use these newer versions of the functions.
17190 - errno: binfmt/, configs/, graphics/, libc/, mm/, net/, sched/: OS
17191 references to the errno variable should always use the set_errno(),
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
17203 NFS server are required to fill up the user provided buffer,

17891 completes, and tries to close the serial port. But if there is
17892 buffered Tx data, then the close will hang when it tries to drain
17894 discards the buffered data and permits the close to continue.
17895 There is additional logic in nuttx/drivers/serial needed to work
17900 - apps/canutils/libuavcan. Removed! libuavcan has not built for a
17904 there is no alternative but to remove it.
17908 - apps/netutils/tftpc: Modified the TFTP client functions to use a
17909 data read/write callback instead of a file. This allows TFTP to
17910 write to arbitrary destination (in my case, a MTD device - for
17916 existing applications, eg the associated nsh commands don't need to
17921 - apps/wireless/bluetooth/btsak: Added a Bluetooth debug tool.
17929 - sched/sched: Fix a deadlock in SMP mode. Two months ago, I
17930 introduced sched_tasklist_lock() and sched_tasklist_unlock() to
17932 audio streaming aging test with lc823450-xgevk. However, I found a
17935 this case, call sequences were as follows. To avoid this deadlock,
17938 call. Also added critical sections to lib_filesem.c, mm_sem.c, and
17940 - sched/sched: Change ordering of round-robin time slice check
17947 even has a chance to run. From EunBong Song.
17951 - fs/fat: In fs_stat(), when stat'ing the root directory, avoid
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
17961 than 4GB will overflow uint32_t type. Solution is to use uint64_t

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
17975 differently than other host commands; Fix ROM CHIPID. Appears to
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
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
17991 nonblocking I/O over buffered tcp socket From Dmitriy Linikov.
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
17998 sending. This matches the standard network (Ethernet) TCP send
18000 - net/udp: Fix several issues using connected UDP sockets: sendto()
18003 recvfrom() and poll() should not reset to accept any addresses but
18009 - net/udp: Resolve race condition in connection-less UDP sockets with
18010 read-ahead buffering. In connection-mode UDP sockets, a remote
18014 connection-less UDP sendto: A temporary remote address is written
18015 into the connection structure to support the sendto() operation.
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-
18020 ahead buffer to fail, dropping UDP packets. Shortening the time
18024 was added to the connection structure to indicate if the UDP socket
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
18036 case where XBee module fails to respond to a Transmit request with

18058 success, the TCFLSH IOCTL logic needs to explicitly set the return
18059 value (ret) to zero.
18060 - drivers/serial: Added a timeout to uart_tcdrain(). Even if
18061 tcflush() is used to discard buffered data, the close() can still

20406 anyway. (2) Explicitly sets the expected PHY address to zero (this
20407 could be moved into the config rather than searching for it which
20411 the PHY to be optional when a reset is needed. If a non-renegotiated
20412 reset doesn't result in good comms to the PHY then it'll automatically
20413 be escalated to a renegotiated one. (4) Only performs a reset for
20416 and might need to be revisited, but certainly the jabber errors don't
20418 anyway. (5) Re-loads the multicast table on reset. (6) Adds a bit
20420 - i.MXRT LPI2C: Fixes 2 bugs in the for IMXRT1050: (1) I2C time out and
20423 - i.MXRT LPSRTC: SVNC LPCR register bits 0 & 1 are NOT reserved and

20717 interrupt duration calculation to use the same high-resolution,
20718 platform-specific timer as is used with the Critical Section Monitor.
20719 This leads to two improvements: (1) You can now measure interrupt
20720 duration in non-Tickless mode, and (2) in either mode, the interrupt
20722 high-resolution timer and should, therefore, never be any discrepancy
20723 due to different clock sources. From Gregory Nutt

21251 line-drawing character (ALTCHARSET) when using the short 16-bit chtype.
21252 This is done by limiting the characters to 7-bit ASCII values and using the
21253 8-th bit as the A_ALTCHARSET bit. This allows a significant RAM savings 4K
21254 - 20K depending on terminal size) while still allowing the nicer
21255 line-graphic characters for border drawing. From Ken Pettit
21259 - apps/testing/ostest: Add test for pthread-specific data. From Gregory
21268 - Assertions: Identify the running task correctly when dumping task

21283 mode to find the right stack for the CPU IDLE thread and could still
21285 - Interrupt Prioritization: Remove all driver-specific logic that may
21286 set the interrupt priority to anything but the default. There is no
21287 good reason to change the interrupt priority unless you just want to
21288 debug a difficult problem. OR if you want to use high priority
21290 to be set by board-specific logic. From Gregory Nutt
21291 - Memory Management: Revert "This patch prevent heap corruption as in
21292 below case." This solution to the problem noted by EunBong Song

21297 memory until failures and bad behaviors begin to occur. From Gregory Nutt
21298 - Memory Management: This is a replacement for EunBong Song's reverted
21299 change. This change adds (1) logic in getpid() to return an error instead

21346 - opendir(): Corrects a problem with opendir() noted by Petteri
21359 ( '.' ) were appended to the pathname." So for mount points,
21360 opendir() works correctly, but for FAT32 filesystem it fails to open

21393 - 6LoWPAN: Fixes decompression of ipaddr from MAC address. The logic
21394 used to populate the IP from the radio address should match
21396 - 6LoWPAN: Fixes logic surrounding the Universal/Local bit. This bit
21398 bit is bit 1 of the MSB of the EUI-64. It should only be inverted in
21399 cases where there is a full EUI-64. In cases where the IID is derived
21400 from say, a short address, this bit should be forced to 0, indicating

21689 'sh' command completes, causing a restore from un-initialized variables,
21690 thus leading to a crash. See the code snippet below for an example test

21714 - apps/system/vi: Bug fixes:
21717 2. Insertion of line above 1st line using 'O' caused line to be
21721 4. The cursor was not being bound to the line end and was allowed to
21722 'hover' over the '\n' EOL character. This caused weird (relative to
21726 account when calculating 'curpos', 'prevpos' variables causing
21729 document instead of simply yanking to the paste buffer. Fixed.
21730 7. The 'dd'elete line function was not copying the deleted line to the
21736 preserved and moved further and further to the left column based on
21739 causing the responsiveness to be unbearable. Fixed. Added logic to
21740 dynamicall indicated which portions of the screen need to be updated
21741 (full display, current line to end of screen, current line only,
21744 at a time by calling the vi_putch() function, causing slow
21749 characters causing lines to be joined. This is different from
21752 13. When in 'ex' or find sub-modes (':' or '/' bottom line modes),
21753 hitting backspace with empty text did not return the operation to
21756 cursor position to the end of the file and did not wrap like in
21759 would force a call to 'vi_extendtext', marking the file as modified
21762 to save code space since they are nearly identical routines.
21765 simply moves the cursor left / to the previous line. Fixed.
21766 18. Added code to handle boundary conditions when the file is new and
21767 commands are applied to an empty file.
21768 19. Fixed vi_shrinktext so it doesn't allocate a zero-length buffer when
21770 20. The 'x' command was not copying to the paste buffer. Fixed.
21771 21. Fixed parsecolon routine to properly deal with ":wq" command sequence.

24100 MMCSD, if we are being told there is a card, but we fail to
24101 initialize it, we should not re-register for an insertion event as
24102 this will immediately cause us to call in again. Instead, we should

24493 NuttX-8.1 Release Notes
24494 ------------------------
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
24508 change to the OS that makes it more-or-less incompatible with preceding
24509 versions. This release bumps the major version number from 7 to 8 due
24510 primarily to a major reorganization in the what was the configs/ directory
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
24535 changes include changes to tools/, comments, and documentation that depend
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
24544 You have to give Alin credit for his effort to take on really big jobs and
24547 A more constrained re-organization of the drivers/ directory was also
24549 directories to make better functional associations and also to make space
24550 for a new set of RF-related drivers.
24553 ---------------------------------------------------
24557 - POSIX Message Queues: Add a test to verify that message queue is
24561 issue: It would be a strange programming practice to open a
24564 - Signal Notifications: Add configuration option to select either the
24565 high-priority or low-priority work queue for SIG_EVTHREA
24567 - System Calls: In order to support built-in in function in protected
24573 parameters. This is a soft limit but still difficult to extend
24574 because it involves assembly language changes to numerous
24575 architectures. Better to get more creative. Rather than extend the
24577 instead to marshal the seven parameters into a structure and pass
24578 only a single parameter: A pointer to the structure containing the
24580 - /etc/passwd and /etc/group: Improve the format of the /etc/passwd
24582 more similar to other systems and includes user and group IDs. Add
24583 also an /etc/group file to support future testing. From Gregory

24597 call. This is so that the calls can be instrumented to monitor the
24598 IOB resources and to collect usage statistics. From Anthony
24600 - IOB ProcFS: Adding ProcFS support at /proc/iobinfo to show the data
24602 - Versioning: Report GIT information via ProcFS. GIT info reported:
24608 - BinFS: The BinFS file system uses the same built-in library and
24609 built-in arrays as does NSH. The built-in arrays are simple name-
24610 value pairs that map built-in function names with the user-space
24611 entry point. In the FLAT build, the built-in arrays are available
24614 reference to the user-space built-in array. This commit adds those
24616 used by applications to the provide the built-in list reference to

24680 IEEE802154_ATTR_PHY_FCSLEN which the radio layer can support to
24681 set/get the FCS length that's added to the end of the frame. One
24682 use case, in promiscuous mode, is to add back in the FCS of the
24683 received frame by increasing the iob->io_len by the FCS length.
24685 - Xbee: Support "WR" AT command for writing parameters to non-
24687 - Xbee: Add configuration option for setting the default prefix

24913 - Nucleo-L432KC: Added GPIO drivers for use with /apps/examples/gpio.
24915 - Nucleo-L432KC: Added Zero Cross sensor to nucleo-l432kc. From
24920 - Tiva: Add support for Tiva TM4C123AH6PM. From Nathan Hartman.
24921 - Tiva Configuration: Modify preprocessor logic to support
24922 configurations with no UART. Now similar to logic for other
24924 - Tiva Interrupts: Add handling for IRQs 128 through 159. From Nathan
24929 - TM4C QEncoder: Reinstate TM4C qencoder driver and expand its
24930 ioctls. Add TIVA_HAVE_QEI0, TIVA_HAVE_QEI1 as applicable to each
24935 Rename TIVA QEI ioctl QEIOC_PPR to QEIOC_RESETATPPR; add TIVA QEI
24941 - TM4C1294-Launchpad: Enables /dev/userleds in board bring-up for
24942 tm4c1294-launchpad by calling userled_lower_initialize() in
24947 - Tiva GPTM timers: Implement 16-bit PWM mode. Add
24948 tiva_pwm16_sel_event() to choose GPTMCTL.TnEVENT value. Implement
24949 tiva_pwm_mode16(). This also involved numerous corrections to the
24950 16-bit timer logic. Add tiva_timer16pwm_setperiodduty() to set
24953 tiva_timer16_start() is called. Add tiva_timer16pwm_setduty() to
24955 flags to enable configuring the 16-bit PWM feature. Extend type of
24956 "flags" in tiva_timer32config_s and tiva_timer16config_s from 8- to
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
24967 export continues without interruption. It would be more logical to
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()
24985 implementation and DT_* definitions to include/dirent.h. Apparently
24988 - libs/libc/grp/: Added stubbed implementations of getgrgid,
24992 The intend is not to provide meaningful new features, but to ease
24993 porting of foreign source code to NuttX. From Michael Jung.
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
25001 new features, but to ease porting of foreign source code to NuttX.
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,
25014 but to ease porting of foreign source code to NuttX. From Michael
25016 - libs/libc/unistd/: Add getuid() and getgid() stubs to match
25018 - libc/libc/unistd/: Add stubs for geteuid(), getegid(), seteuid(),
25026 - NuttX provides lists of available syscalls and library functions and
25027 tools to process them. The lists can be used to build symbol table
25030 compilation and linking to the final system image has been possible
25032 (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of
25036 requested by EXECFUNCS configuration. I have tried to follow
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
25047 disabled) and main purpose is to lower memory overhead when more
25050 separation. If the table should be provided by kernel to
25051 applications then makefiles has to be adjusted. From Pavel Pisa.
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
25060 instructions in README.txt files to show ':' delimiter vs '/'
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
25071 nuttx/include/nuttx/binfmt/built.h to nuttx/include/lib/builtin.h.
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
25088 - apps/fsutils/passwd: Handle the improved the format of the
25089 /etc/passwd file. It is now a little more similar to other systems.
25094 - apps/netutils/dhcpc: Add host name support to DHCP client. From
25099 - apps/wireless/ieee802154/i8sak: I8sak improvements: (1) Adds
25102 fault can occur due to not catching missing arguments. From
25104 - apps/wireless/ieee802154/i8sak: Allow setting the endpoint PAN ID.
25106 - apps/wireless/ieee802154/i8sak: Adds support for energy scan result

25113 - apps/wireless/gs2200m: Add UDP support to the GS2200M driver. From
25115 - apps/wireless/gs2200m: Add DHCP client handling in ioctl_request().
25117 - apps/wireless/gs2200m: ioctl_request() supports SIOCGIFHWADDR.
25121 ---------
25128 - Priority Inheritance: Fix a race in telnet with PRIORITY_INHERITANCE
25129 and SCHED_HPWORK. Sometimes causes an assertion to fire incorrectly.
25131 - Task Groups: Correct some naming. The NuttX task groups have been
25134 group permissions. So these were all named to grpid and grpid_t so
25135 that it is clearer that these refer to NuttX task group IDs, and not
25136 to group permissions. From Gregory Nutt.
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
25140 can send the SIGCHLD signal to it. So it must stay valid until
25142 nxtask_sigchild() to send SIGCHLD to the parent, then invalidates
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
25153 was created specifically to support the NuttX internal, SMP
25154 implementation. Any resemblance to any other cpu_set_t would be
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
25162 - Binary Loader: Change some debug macros from berr() to binfo()
25166 overlooked. The huge output sent to serial terminal slows loading
25168 - Power Management: Fix g_pmcount 16-bits overflow when
25170 - Timekeeping: Fix cases in time conversion that must be >=
25175 - opendir(): opendir() set errno to a negative value in one error

25178 - ProcFS: Add missing LF to cpuload procfs output From David Alessio.
25179 - MMC/SD: Copy/paste error fix in the SDIO-based block driver for
25181 - MMC/SD: Correct a misplaced #endif in the SDIO-based driver. From
25186 - Ethernet Configuration: Ethernet packet buffer size cannot be
25187 permitted to go below 1294 if IPv6 is selected. From Gregory Nutt.
25188 - TCP RST: Fix outgoing RST packet with wrong ack number. From
25190 - TCP Close: Fix TCP close flow; free the connection after all TCP
25192 - UDP Broadcast: Remove net stack dependency from CONFIG_NET_BROADCAST.
25193 This change allows us to use CONFIG_NET_BROADCAST without network
25196 - UDP: Fixes a UDP send copy-paste error in the new SO_LINGER code:
25197 CONFIG_TCP_NOTIFIER to CONFIG_UDP_NOTIFIER. From Juha Niskanen.
25198 - TCP and UDP: Fix errors in the new implementation of SO_LINGER.
25200 argument to the wrong type, resulting in hangs and abnormal
25201 behavior. There is a complexity in the TCP drain logic when the
25207 - 6LoWPAN: Removes unnecessary conversions that were happening due to
25208 a misunderstanding of byte ordering with EUI-64. From Anthony
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
25218 attempts to get forwarded on the 6LoWPAN interface will require
25219 that the radio's buffer be attached to d_buf. Otherwise an assertion
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
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
25243 set to 3 when payload exceeds version 0 capabilities. Adds warning
25244 to build to indicate what is noted in the menu for
25246 - IEEE 802.15.4 MAC: Fixes issue where the txdesc's ackreq flag was
25249 - Xbee: Fix logic to prevent deadlock scenario when there are no
25250 available IOBs From Anthony Merlino (2018-12-21).
25251 - Xbee: Change assumption about destination address mode for incoming
25252 frames. If a short address has been assigned to our radio, then
25255 - Xbee: Initialize the short address to the unspecified address and
25258 - Xbee: Adds CONFIG_XBEE_LOCKUP_WORKAROUND option and corresponding
25259 logic to workaround an issue where the XBee locks up and stops
25263 occasionally the XBee is completely locked up and the XBee has to
25268 - Xbee: Cancel query timeout upon receiving the expected response.
25270 timeout to continue firing repeatedly From Anthony Merlino.
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
25281 - pipes: Use inode reference counter instead of device reference
25282 counter to handle dup(). I found that if I dup() a pipe, the

25290 - GPIO Lower Half: Remove limitation when pintype >
25295 - Classic ARM7/ARM9: When performing stability test, the application
25301 Fix is to use a single ldmia to restore R0, R1, and return via R15.

25306 - ARMv7-A: Fix typo and missing quotation for ARMv7-A. From Oki
25308 - ARMv7-A: Fix double increment in armv7-a's
25310 - ARMv7-A: Fix L2 page table mask for ARMv7-A page allocator. From
25313 * ARMv7-M
25315 - Interrupts. Removes the architecture-common
25317 supported only by ARMv7-M). In the normal course of things,
25319 inline function to prevent contention in use of resources that may
25320 be shared between interrupt level and non-interrupt level logic.
25321 Now the question arises, if we are using BASEPRI to disable
25325 the "normal" interrupts? If we are using the BASEPRI register to
25331 Hence, if you need to disable the high priority interrupt, you will
25332 have to disable the interrupt either at the peripheral that
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
25348 - i.MXRT LPI2C: Slave addresses are now correctly shifted when
25349 sending START. TX/RX FIFOs now discarded on error to prevent FIFO
25350 underflow errors. Fixes error checking to use priv structure and
25356 - PIC32MZ SPI: Fix SPI Mode selection. CKE is the inversion of the
25361 - SAMD2/L2 I2C: Correct time calculation. From Bernd Walter.
25365 - SAM3/4: Add missing DMA configuration Kconfig setting. From Bernd
25370 - LPC17xx/40xx ADC: Only use PCLKSEL0 for ADC on LPC176x family.
25372 - LPC17xx/40xx Ethernet: Set speed back to 10Mbps if 10Mmbps link
25374 - LPC17xx/40xx I2C: Abort I2C transfers if a timeout has occurred.

25399 because CCLK frequency does not correspond to PLL0 clock which is
25401 be probably better to define BOARD_PCLK_FREQUENCY even for LPC176x
25402 targets and use that to replace divisor by base_clock in up_dev_s.
25407 - LPC17xx/40xx Ethernet: Add missing LPC17_40_PHY_CEMENT_DISABLE
25408 variable to the lpc17xx/40xx Kconfig file. For some reason this
25411 - LPC17xx/40xx Ethernet: Fix the initialization for DP83848x PHYs.
25412 The DP83848x requires the RMII mode to be manually enabled through
25414 it should wait for the link to be established. From Augusto Fraga
25419 - i.MXRT LPUART: Fix some errors in the LPUART register definition
25421 be imxrt_earlyserialinit(). Remove prototypes for non-existent
25423 - i.MXRT USDHC: uSDHC typo fixes and command transfer error handling
25428 - EFM32 OTG host: Adam Porter's various fixex for STM32 FS/HS
25429 probably should be applied to EFM32 host which which has very
25434 - STM327F Configuration: Kconfig add depends on BBSRAM. From David
25436 - STM32F7 Interrupts: Fix overwritten IRQ enable. System boot order
25439 This most likely worked in the past due to a bug in the NVIC
25440 initialization code that failed to clear the Interrupt enables.
25441 - STM32H7: Rix BBSRAM name in memory map. From David Sidrane.
25442 - STM32H7: Removed f7 in file path. From David Sidrane.
25446 - STM32H7 BBSRAM: Fix issues causing no writes and hardfaults. From
25448 - STM32H7 BBSRAM: Convince compiler to perform 32 bit write. From
25450 - STM32F7 OTGHS: Fixes bad preprocessor logic preventing USB OTG HS
25451 to work when used without external ULPI. From Anthony Merlino.
25452 - STM32 OTGH[FS|HS] Host STM32 host only initiates transfer if
25454 - STM32F7/H7/L4 OTG host: Adam Porter's fix for STM32 FS/HS probably
25455 should be applied to STM32 F7, H7, and L4 OTG host which are very
25457 - STM32/F7/H7/L4: This change was required to get my devices
25458 (CDC-MBIM) to enumerate. Initially the system timed out retrieving
25465 'timeout'. The fix I implemented moves the DATANAK timeout loop to
25466 only apply to the Status OUT. Both the ctrl IN and the Status OUT
25468 - STM32F7 SDMMC: If there is only one SDMMC it is slot 0 From David
25470 - STM32F7 USART1: USART1_RXDMA is dependent on STM32F7_DMA2 not
25472 - STM32H7 DBGMCU: Memory Map DBGMCU is @ 0x5c001000 From David
25474 - STM32F7 SDMMC: Fix warning when DMA is not enabled. From David
25476 - STM32H7 Ethernet: Fix some errors in Ethernet MAC configuration.
25478 - STM32H7 Ethernet: Correct stm32h7 mac address filtering. Correct
25480 flag. Now the Ethernet driver only receives packets addressed to
25482 - STM32H7 Ethernet: Correct memory corruption error. The Ethernet
25483 driver initialization incorrectly wrote to DMACRXCR instead of
25484 DMACSR when trying to clear the stopped flags. This caused
25485 invalid buffer length in the DMACRXCR, causing DMA to overflow the
25486 RX buffers when large packets are sent to the device. From Jukka
25488 - STM32H7 PWR: Ensure data is flushed on backup domain access
25490 - STM32H7 Serial: Serial fix undefined with TERMIOS From David
25492 - STM32H7 UARTs: Fix UART7/8 typos. Fix bug in ETH_MACQTXFCR

25501 - Nucleo-H743ZI: Correct logic that determines if the RTC driver is
25503 - Nucleo-G071RB: Fix linker script to avoid .ARM.exidx section
25505 - Modify all linker scripts (all boards, all architectures) to use
25507 - Nucleo-L432KC ADC: Change analog pins definitions and correct DMA
25512 - Tiva Configuration: Rename TM4C123GH6PMI identifiers to
25517 which means it doesn't make sense to differentiate between PM and
25518 PMI. (The PM means 64-LQFP. The I means temperature range -40C to
25519 +85C. It could be T meaning -40C to +105C. The R means it ships in
25520 Tape and Reel packaging as opposed to Tray.) From Nathan Hartman.
25521 - Tiva Configuration: Rename TM4C1294NC identifiers to TM4C1294NCPDT.
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
25525 "Connected LaunchPad" (see configs/tm4c1294-launchpad). To ensure
25527 TM4C1294NC identifiers to TM4C1294NCPDT. From Nathan Hartman.
25528 - Tiva Configuration: Fix TM4C129XNCZAD part number in Kconfig and
25529 identifiers. Rationale: Fully specify that this is the 212-pin BGA
25530 package (ZAD ending) and for consistency with earlier changes to
25536 - Tiva TM4C 1-Wire: Fix wrong description on define TIVA_1WIRE_BASE:
25537 Was "EEPROM and Key Locker" (same as the item above). Now "1-Wire
25543 - Tiva GPIO Interrupts: LM3S, LM4F, TM4C: Fix GPIO IRQ error, ports
25548 - Tiva Timers: Fix minor errors in tiva_timerlib.c. Fix incorrect
25549 preprocessor conditionals related to Kconfig defines:
25550 CONFIG_TIVA_TIMER32_EDGECOUNT -> CONFIG_TIVA_TIMER16_EDGECOUNT,
25551 CONFIG_TIVA_TIMER32_TIMECAP -> CONFIG_TIVA_TIMER16_TIMECAP,
25552 CONFIG_TIVA_TIMER32_PWM -> CONFIG_TIVA_TIMER16_PWM. From Nathan
25554 - Tiva Timers: Fix errors in low-level timer support.
25559 - Tiva Timers: Fix one code error and some comment errors.
25561 TIMER16_MODE. Fixed to DEBUGASSERT on mode == TIMER16_MODE.
25566 - z80sim Serial: Fix uart_dev_t initializer: pollfds[] is a array of
25569 - z80sim Interrupts: Missed a name change up_irqinitialize to
25574 - include/netinet/in.h: Rename __pad member to sin_zero in struct
25576 sockaddr_in objects to zeros. Apparently, judging from mailing list
25580 the 'nuttx' nor in the 'apps' repository did I find any reference to
25581 this identifier. Thus, I believe its a safe bet to just rename it.
25584 sin_family, sin_addr, and sin_port. It is acceptable for a POSIX-
25585 compliant implementation to define additional structure members, and
25590 - libs/libc/libc.csv: Correct dependency of setlocale on
25592 - libs/libc/machine/arm/armv7-m: Fix build error for ELF. From
25594 - libs/libc/math.csv: Correct format of some function entries. From
25599 - tools/: Change all occurrences of /bin/(ba)sh in shell scripts to
25604 - apps/nshlib/: As noted by David S. Alessio, 'cat' should not output
25606 additional newline was added to assure that the NSH prompt was
25610 written to the standard output." Reference:
25615 other commands implemented via nsh_catfile(). That remains to be
25620 - apps/system/cle/: ASCII DEL should be treated by Delete-Left. From
25622 - apps/system/i2ctool: (1) Friendlier I2C "knock-knock" uses only
25626 attempting to index to "Reg[0]" alters its contents to 0x00
25628 simply trying to read something/anything from the slave. This also
25632 Reg[80]-Reg[8F] and will NAK a read of Reg[0]. (2) Modify get/set
25633 to prevent write of reg index if not specified From David Alessio.
25637 - apps/netutils/dhcpd: Fixes bug where hwaddr was being used instead
25638 of ipaddr in the ARP update. This bug seems to have been introduced
25639 three years ago during a rewrite to remove a direct OS call to arp.
25641 behavior I was observing was that the DHCPD would go to offer an IP
25643 didn't know where to send the data. From Anthony Merlino.
25644 - apps/netutils/netinit/: Remove warnings. Unhook PHY notification
25650 - apps/wireless/ieee802154/i8sak: Fixes conversion from extended
25651 address to IPv6 address. From Anthony Merlino.
25653 NuttX-8.2 Release Notes
25654 ------------------------
25658 that release consists of two tarballs: nuttx-8.2.tar.gz and
25659 apps-8.2.tar.gz. These are available from:

27126 * Compatibility Concerns -- Changes to Build System:
27128 If you are building NuttX for a custom board, you may need to make
27129 some of the following changes in build-related files for your board:
27131 * Rename EXTRADEFINES to EXTRAFLAGS
27133 In your custom board's scripts/Make.defs file, rename EXTRADEFINES to

27159 If you forget to do this, memory allocations on the heap probably won't
27162 To see why, tools/Config.mk assigns a value to KDEFINE such that the
27164 files are compiled. KDEFINE is passed to nested invocations of 'make'

27374 NuttX-10.0.0 Release Notes
27375 ------------------------
27377 ## Major Changes to Core OS
27381 Major changes to the internal, OS timer (wdog) interfaces. The change includes:
27383 * The wdog timer call backs used to support a variable number of arguments.
27385 #1565](https://github.com/apache/incubator-nuttx/pull/1565)). This eliminates
27388 pre-allocated. Now they are allocated by the caller of `wd_start()`. This (1)
27391 type to `struct wdog_s`, and (3) change the type of the first argument of all
27392 remaining wdog interfaces functions from `WDOG_ID` to `FAR struct wdog_s *`.
27398 changed to `struct wdog_s wdog`; That changes the field from a pointer to a
27399 `struct wdog_s` to the `struct wdog_s` storage itself. * Eliminate all calls
27400 to `wd_create()`. The `WDOG_ID` is not longer managed by the timing subsystem
27402 interface has also been removed, but more care will need to be exercised:
27403 `wd_delete()` also cancels any running timer so, in many case, calls to
27404 `wd_delete()` should be replaced with calls to `wd_cancel()`. If you are certain
27405 that the timer has never been started, then you must remove the call to
27406 `wd_delete()` altogether. Calling `wd_cancel()` with an un-initialized s`truct
27409 = wd_cancel(priv->wdog)` where `priv->wdog` was type `WDOG_ID` with the call
27410 `ret = wd_cancel(&priv->wdog)`where `priv->wdog` is now type `struct wdog_s`.

28458 ## Changes to Build System
28460 ### In Apps, Change `$(TOPDIR)` to `$(APPDIR)`
28464 In your custom app's Makefile, it is recommended to change `$(TOPDIR)` to

28482 As part of an effort to unify support for uClibc++ and libc++, the C/C++ include
28484 one central place in `tools/Config.mk`. It is no longer necessary to define
28487 and are using C++, you may want to make the following changes:
28494 CINCPATH := ${shell $(INCDIR) -s "$(CC)" $(TOPDIR)$(DELIM)include} CXXINCPATH :=
28495 ${shell $(INCDIR) -s "$(CC)" $(TOPDIR)$(DELIM)include$(DELIM)cxx} ARCHINCLUDES
28499 instead of `ARCHXXINCLUDES`, you'll need to find all uses of that variable and
28500 update them to use `ARCHXXINCLUDES`.

28515 compiler and C flags. Previously, every board's `scripts/Make.defs` file had to

28518 provided by logic in `tools/Config.mk`. Boards included in the NuttX repository

28528 ifeq ($(CONFIG\_WINDOWS\_NATIVE),y)
28529 HOSTCC = mingw32-gcc.exe
28537 definitions will override the ones in tools/Config.mk.

28541 versions of these host binaries: define HOSTCFLAGS with -g on the command line.

29540 ## Changes to Build System
29542 ### Change CFLAGS, CPPFLAGS, CXXFLAGS, and AFLAGS from Recursive to Simple Assignment
29544 [PR-1890](https://github.com/apache/incubator-nuttx/pull/1890)
29545 (commit [2caf3a69e3d60ec550980f7ba897c732e7a39df7](https://github.com/apache/incubator-nuttx/pull/1…
29546 attempts to speed up compilation time for concurrent builds by changing
29547 assignment to makefile variables `*CFLAGS*`, `*CPPFLAGS*`, `*CXXFLAGS*`, and
29548 `*AFLAGS*` from recursive `=` to simple `:=`. This causes these compile
29549 options to be expanded only once during the build.
29552 want to make a similar change to your `Make.defs` files. Change these
29556 …RCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
29557 …ARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
29559 AFLAGS = $(CFLAGS) -D__ASSEMBLY__
29562 to simple assignments:
29565 …RCHWARNINGS) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
29566 …ARNINGSXX) $(ARCHOPTIMIZATION) $(ARCHCPUFLAGS) $(ARCHXXINCLUDES) $(ARCHDEFINES) $(EXTRAFLAGS) -pipe
29568 AFLAGS := $(CFLAGS) -D__ASSEMBLY__
29571 ### Not Necessary to Define `__NuttX__` in Make.defs
29573 [PR-2192](https://github.com/apache/incubator-nuttx/pull/2192)
29574 (commit [9208176f600d0d04446531909bf05710716a5ee4](https://github.com/apache/incubator-nuttx/commit…
29575 refactors definition of the `__NuttX__` preprocessor symbol to
29576 `tools/Config.mk`, so it is no longer necessary to define it in each board's
29580 want to make a similar change to your Make.defs files.
29585 ARCHDEFINES = -D__NuttX__
29588 Or remove -D__NuttX__ from lines like this:
29591 CXXFLAGS += $(ARCHDEFINES) $(EXTRAFLAGS) -pipe -std=c++11 -D__NuttX__

30449 Some variables to look for:
30451 - `ARCHSCRIPT`
30452 - `ARCH_LIBS`
30453 - `CCLINKFLAGS`
30454 - `EXTRALINKCMDS`
30455 - `LDELFFLAGS`

30460 - `LDSTARTGROUP`
30461 - `NXFLATLDFLAGS1`
30462 - `NXFLATLDFLAGS2`
30463 - `USER_LDFLAGS`
30468 $(Q) $(LD) --entry=__start $(LDFLAGS) $(LIBPATHS) $(EXTRA_LIBPATHS) \
30474 $(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map"
