8788 LSI and the LSE sources: the LSI can be used for RTC and/or the
8789 IWDG, while the LSE only for the RTC (and to output the MCO1 pin).
8790 This change is not verifed for any other platforms. From Leo
8795 - Tiva GPIO driver needed small fixes in the configuration routines and
8796 discovered false-positive bugs in interrupt testing: interrupts are

8813 - Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all
8814 exhibited bad cancellation errors near zero (<= 1E-10). This can be
8815 easily seen e.g. with x = 1E-30, the results are all zero though they
8816 should be extremely close to x. The cutoff values (1E-5, 1E-9) are
8817 chosen so that the next term in the Taylor series is negligible (for

12204 - lib_dumpbuffer() now prints a large on-stack buffer first to avoid
12206 Pierre-noel Bouteville.
12207 - libc/math: This fixes the following libc/math issues: (1) asin[f l]()
12209 converges very slowly (> 500,000 iterations) for values of x close to
12211 forever). The attached patch uses an trig identity for values of
12212 x > sqrt(2). The resultant functions converge in no more than 5
12213 iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions are
12216 x near -3.0. This patch fixes that problem. It should be noted that
12218 less than 1.2E-07 and that�s fine for the float version erff(), but
12219 the same method is used for double and long double version which
12221 address the issue of lower precision for erf() and erfl(). (3) a
12222 faster version of copysignf() for floats is included. From David S.
12224 - strtod() was not returning endptr on error conditions.
12225 - libc/math: floor(), floorf(), and floorl(): Fix logic error. Was
12227 - isatty() should be prototyped in unstid.h, not termios.h. From
12229 - nxglib: Fix handling of near-horizontal lines of width 1 in
12230 nxgl_splitline(). Missing handling for degenerate condition caused
12231 width 1 lines such as (0, 0) - (100, 10) to have gaps in the
12236 - Top-Level Makefiles: Fix a chicken-and-egg problem. In the menuconfig
12237 target, the context dependency was executed before kconfig-mconf. That
12240 Kconfig files would not be included. But this introduces the chicken-
12241 and-egg problem in some configurations. In particular: (1) An NX
12242 graphics configuration is used that requires auto-generation of
12243 source files using cpp, (2) the configuration is set for Linux, but
12245 In this case, POSIX-style symbolic links are set up but the Windows
12248 fails. During the context phase, NX runs CPP to generate source files
12251 menuconfig (and related) targets. They no longer depend on context
12254 to run all of the context setup; the compiler is never invoked; no
12256 - CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From
12261 - tools/refresh.sh: Recent complexities added to apps/ means that

12635 introduced in NuttX-7.15. Work has continued on this effort on
12638 least NuttX-7.20.
12641 ChangeLog for the complete list of bugfixes and for additional, more
12646 - sched/semaphore: Within the OS, when a thread obtains a semaphore
12649 sem_addholder(), otherwise it waited for the semaphore and called
12656 restarting the thread waiting for the semaphore count. This problem
12658 - Many files: Make sure that priority inheritance is not enabled for
12661 - sched/semaphore: sem_trywait() no longer modifies the errno value
12664 - sched/clock: Correct clock initialization. The correct range for the
12665 month is 0-11 but is entered as 1-12 in the .config file. Add ranges
12667 - sched/clock: Correct calculation for the case of Tickless mode with a
12668 32-bit timer. In that case, the calculation was returning millisecond
12671 - Work Queue: When queuing new LP work, don't signal any threads if
12673 - Work Queue: Signal sent from work_signal() may interrupt the low
12674 priority worker thread that is already running. For example, the
12675 worker thread that is waiting for a semaphore could be woken up by the
12679 - Fix DEBUGASSERT() in group_signal.c. From Masayuki Ishikawa.
12680 - Eliminate bad boardctl() commands: Remove all references to
12685 - pthreads: Fix an error in pthread_mutex_destroy(). An error could
12688 - task_restart: Make sure new task starts with pre-emption disabled and
12690 - Enter/leave Critical Sections. Major redeign to
12695 - SMP Critical Sections: Fixes for the SMP case: (1) Change order for
12699 - SMP wdogs: Wdog timers use a tasking interface that to manipulate
12703 are disabled and no conflicts can occur. But that may not be the case
12707 locking (via enter_critical section) to wdog expiration logic for the
12709 - SMP vfork(): Fix a race condition in the SMP case. Existing logic
12714 - SMP: This change adds a new internal interfaces and fixes a problem
12728 - SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting
12729 for g_cpu_irqlock with interrupts interrupts and CPU0 is waiting for
12731 - SMP: Enforce this rule: Tasks which are normally restored when
12734 still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In

12798 - ARMv7-R: Remove the redundant update on SCTLR. mpu_control() is
12801 - ARMv7-R: Add new Kconfig entries for D/I-cache. Unlike in ARMv7-A/M,
12802 Kconfig entries for data and instruction caches are currently missing
12803 in ARMv7-R. This change adds those missing Kconfig entries. Actual
12804 implmenetation for those functions will be added in the subsequent

12859 - SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to
12860 CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node
12862 not connected to the can-bus. The CAN-Standard declares, that the Chip
12865 to resend the message an Acknowledge-Error-Interrupt is generated. At
12866 high baud rates this can lead in extremely high CPU load just for
12868 application). To prevent this Interrupt-Flooding we disable the ACKE
12871 - SAMV7 MCAN: Make delete_filter functions more robust. From Frank
12876 - SAMA5 PWM: Driver does not build when executing from SDRAM before
12884 - Misoc LM32: Corrects a bug that never occured in qemu on simulation or

17902 there is no alternative but to remove it.
17906 - apps/netutils/tftpc: Modified the TFTP client functions to use a
17908 write to arbitrary destination (in my case, a MTD device - for
17909 firmware update). Two new functions are introduced for this, named
17919 - apps/wireless/bluetooth/btsak: Added a Bluetooth debug tool.
17922 ChangeLog for the complete list of bugfixes and for additional, more
17927 - sched/sched: Fix a deadlock in SMP mode. Two months ago, I
17929 protect tasklists in SMP mode. This change works well for HTTP
17930 audio streaming aging test with lc823450-xgevk. However, I found a
17937 net_lock.c for SMP for SMP. From Masayuki Ishikawa.
17938 - sched/sched: Change ordering of round-robin time slice check
17949 - fs/fat: In fs_stat(), when stat'ing the root directory, avoid
17953 - fs/fat: Avoid calculating the bogus directory entry address for
17954 the FAT root directory (since it has no directory entry). This
17955 change should have no effect, other than making the logic clearer.
17957 - fs/mount: Fix wrong size reported by df -h. Reason is that size
17961 - fs/smartfs: Fix a hardfault in SmartFS. Problem occurred when
17964 - fs/vfs: Fix negative errno set in fs_open.c From Michal Lyszczek.
17965 - drivers/mtd: Fixed a W25 driver w25_cacheflush sector bug. From
17967 - drivers/mtd: mtdconfig_register() returned OK instead of -ENOMEM on
17972 - drivers/lcd/ft80x: ACTIVE host command appears to be formatted
17974 be big-ending, BCD. Fix some compile issues when debug features
17976 - drivers/lcd/ft80x: Fix a typo that caused the driver to fail to
17978 - Review all board implementations of board_lcd_initialize(). The
17980 as an 'int' must return a negated errno value on failure and a non-
17984 non-negative.

17995 - net/sixlowpan: TCP send should have PSH and ACK flags set when
17998 - net/udp: Fix several issues using connected UDP sockets: sendto()
18000 connect UDP sockets instead. recvfrom() is no longer necessary.
18007 - net/udp: Resolve race condition in connection-less UDP sockets with
18008 read-ahead buffering. In connection-mode UDP sockets, a remote
18011 recv() will be accepted. This same mechanism is used for
18012 connection-less UDP sendto: A temporary remote address is written
18015 accept any address. When UDP read-ahead buffering is enabled,
18017 in the connection structure for some time. This can cause read-
18023 is in connection mode or if it is connection-less. This change
18025 connection is always ignored if the UDP socket is not in connection-
18026 mode. No for connection-mode sockets, that remote address behaves as
18027 before. But for connection-less sockets, it is only used by sendto().

18126 Reason for hang is that operation of setting LSE_ON does not take
18127 effect because there is no clock on PWR peripheral. This is

18194 - apps/examples/ostest: Do not call AIO test without
18196 - apps/examples/smps: Fix typos in Kconfig. All power, voltage,
18197 current values were strings with no default. I assume they should

20356 no linked DMA descriptor code on the send side. The end result was
20359 - LPC43 SDMMC: With these changes the SDMMC card for LPC43 is now
20362 possible for data to still be in the FIFO (i.e. not have reached the

20397 - i.MXRT Ethernet: Fix a race condition in setting up the Ethernet Tx
20399 - i.MXRT Ethernet: Corrections for the i.MXRT Ethernet: (1) Now the
20400 Ethernet is completely re-initialized when an error occurs by means of
20402 renegotiated for that case because that is very time consuming and an
20403 error in the Ethernet is no reflection on the state of the PHY
20405 could be moved into the config rather than searching for it which
20406 takes ages, and it's zero anyway for this board (that's the broadcast
20408 so that would be a new board). (3) Allows for the renegotiation of
20409 the PHY to be optional when a reset is needed. If a non-renegotiated
20411 be escalated to a renegotiated one. (4) Only performs a reset for
20416 anyway. (5) Re-loads the multicast table on reset. (6) Adds a bit

20873 used as a a direct replacement for arch_invalidate_dcache(). From
20875 - ARMv7-M: In the current implementation we only use very high
20876 priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but
20881 for interrupts to be defined above (or, indeed, below) them as needed
20882 by the application. This should have no functional effect on

24606 - BinFS: The BinFS file system uses the same built-in library and
24607 built-in arrays as does NSH. The built-in arrays are simple name-
24608 value pairs that map built-in function names with the user-space
24609 entry point. In the FLAT build, the built-in arrays are available
24612 reference to the user-space built-in array. This commit adds those
24614 used by applications to the provide the built-in list reference to

25126 - Priority Inheritance: Fix a race in telnet with PRIORITY_INHERITANCE
25129 - Task Groups: Correct some naming. The NuttX task groups have been
25130 using the acronym 'gid' and also the type 'gid_t' for the the task
25131 group ID. That is incorrect. Than naming is reserved for use with
25135 - Task Termination: nxtask_signalparent() in task_exithook.c may
25147 - sched_get_rr_interval(): sched_get_rr_interval() should return
25148 {0,0} if round-robin scheduling is not selected for the task. From
25150 - SMP Type Collision: The non-standard, non-portable type cpu_set_t
25154 occurred. cpu_set_t has an equivalent, non-standard, non-portable
25156 non-standard type to be defined. Who am I to stand in the way of
25160 - Binary Loader: Change some debug macros from berr() to binfo()
25166 - Power Management: Fix g_pmcount 16-bits overflow when

25213 - wireless network devices: Attach radio to d_buf before registering
25223 - IEEE 802.15.4 MAC: Fixes issues with extended address. 1) Extended
25224 address should be read-only. 2) Extended address should be placed
25225 in frame in "reverse-canonical" order. The extended address is a
25226 read-only attribute and thus an attempt to write the extended
25229 bring-up time to the radio layer. The MAC layer now pulls in the
25232 reverse-canonical order. This is very confusing in the standard and
25235 committee for suggestions/feedback on the future standard. It isn't
25238 written in reverse-canonical form, meaning the OUI comes last, not
25240 - IEEE 802.15.4 MAC: Frame Version should have been 1, but was being
25242 to build to indicate what is noted in the menu for

25395 - LPC17xx/40xx CAN: If BOARD_CCLKSEL_DIVIDER is not equal to 1 on
25398 used for PCLK. This is partially workaround solution. It would
25399 be probably better to define BOARD_PCLK_FREQUENCY even for LPC176x
25405 - LPC17xx/40xx Ethernet: Add missing LPC17_40_PHY_CEMENT_DISABLE
25406 variable to the lpc17xx/40xx Kconfig file. For some reason this

25510 - Tiva Configuration: Rename TM4C123GH6PMI identifiers to
25512 is no functional difference between these parts: TM4C123GH6PMI7,
25516 PMI. (The PM means 64-LQFP. The I means temperature range -40C to
25517 +85C. It could be T meaning -40C to +105C. The R means it ships in
25519 - Tiva Configuration: Rename TM4C1294NC identifiers to TM4C1294NCPDT.
25520 Rationale: TM4C1294NC is ambiguous: TM4C1294NCPDT is a 128-TQFP,
25521 TM4C1294NCZAD is a 212-NFBGA. The TM4C1294NC part currently
25522 supported by NuttX is the TM4C1294NCPDT used on the TI EK-TM4C1294XL
