NuttX-7.24 Release Notes
------------------------
The 124th release of NuttX, Version 7.24, was made on March 2, 2018,
and is available for download from the Bitbucket.org website. Note
that release consists of two tarballs: nuttx-7.24.tar.gz and
apps-7.24.tar.gz. These are available from:
https://bitbucket.org/nuttx/nuttx/downloads
https://bitbucket.org/nuttx/apps/downloads
Both may be needed (see the top-level nuttx/README.txt file for build
information).
Additional new features and extended functionality:
* Core OS:
- SMP: Introduce spin_lock_irqsave() and spin_unlock_irqrestore().
These APIs are simplified version of enter_critical_section()
and leave_critical_section() to protect data (e.g. registers) in
SMP mode. By using these APIs inside drivers, performance will
be improved. From Masayuki Ishikawa.
- System Timer: Replace critical section APIs with spinlock APIs.
(64bit only). If SMP=n or SMP=y && SPINLOCK_IRQ=n, this works
in the same way as before. If SMP=y && SPINLOCK_IRQ=y, performance
will be improved. From Masayuki Ishikawa.
- POSIX Timers: Replace critical section APIs with spin lock APIs in
clock_gettime.c. This change will improve performance for SMP
systems but nothing changes for non-SMP systems. In SMP mode,
the running TCB is not always at the g_readytorun.head. From
Masayuki Ishikawa.
- SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note(). These
APIs are used in sched_note.c to protect instrumentation data. The
difference between these APIs to exsiting spin_lock() and
spin_unlock() is that they do not perform instrumentation to avoid
recursive call when SCHED_INSTRUMENTATION_SPINLOCKS=y. From
Masayuki Ishikawa.
- Interrupts: Add a configuration option to show interrupt
information via a procfs file.
* File Systems/Block and MTD Drivers
- VFS: Add support for truncate() and ftruncate().
- FAT, SmartFS, UserFS, UnionFS, TmpFS, NFS: Add truncate() support.
- FAT. Effectively handles the situation when a new file position is
within the current sector. Accelerates the work of the FS with a
multitude of operations to write small pieces of data within the
current sector. From Aleksandr Vyhovanec.
* Graphics/Display Drivers:
- HiletGo OLED: Add configuration support for HiletGo SSD1306 OLED.
- lcd/ft80x: This commit adds an FTDI/BridgeTek FT80x GUI driver. It
is untested (I don't even have hardware yet) and, hence, it is
marked as EXPERIMENTAL).
* Networking/Network Drivers:
- 6LoWPAN: Adds configuration options for specifying preloaded
address contexts for compression From Anthony Merlino.
- TCP: Introduce tcp receive window control based on I/O buffer.
NOTE: The algorithm is still experimental but useful for http
streaming. From Masayuki Ishikawa.
- UDP: Add an implementation of UDP write buffering.
- Routing Tables: Adding ftruncate() support eliminates an issue
in file-based routing table management system.
- Telnet: Add support for Telnet character mode From Masayuki
Ishikawa.

- drivers/input/ft5x06.c: Add a driver for the FT5x06 capacitive,
multi-touch, touchscreen controller.
- drivers/input/ft5x06: Add a polled mode of operation for the FT5x06
in attempt to work around the fact that the LPCXpresso-LPC54628

not yet functional.
- drivers/power/bq2429x.c: Add trickle charging mode From Juha
Niskanen.

- system/stackmonitor: Re-design the stack monitor so that it does not
make forbidden calls directly into the OS, breaking the portable POSIX
OS interface. It now properly uses the PROCFS file system to glean
information about stack usage.
Bugfixes. Only the most critical bugfixes are listed here (see the
ChangeLog for the complete list of bugfixes and for additional, more
detailed bugfix information):
* Core OS:
- System Timer: Change the way that the 64-bit time is sampled.
Previously, we disabled interrupts before sampling the 64-bit
timer since the uint64_t access is not atomic on most CPUs. However,
disabling (local) interrupts does not work in the SMP case. In that
case, the timer interrupt may be running on only one of the CPUs;
disabling interrupts on a different CPU will provide no protection
from timer rollover. To work around this, logic was added that
samples 64-bit timer is sampled twice and if 32-bit rollover was
detected between samples, then loops until there is no rollover.
- POSIX Timers: In SMP mode, running TCB is not always at the head of
the g_readytorun list. This change removes DEBUGASSERT() to avoid
this condition. From Masayuki Ishikawa.
- Spinlocks: Add memory barrier operations in spin_unlock(). In ARM
document regarding memory barriers, SP_DMB() must be issued before
changing a spinlock state to SP_UNLOCKED. However, we found that
SP_DSB() is also needed to ensure that spin_unlock() works
correctly for network streaming aging test. From Masayuki Ishikawa.
- Sporadic Scheduler: Fix compiler error in Sporadic Scheduler when
priority inheritance is enabled. Noted by eunb.song@samsung.com
- Priority Inheritance: Fix some priority inheritance related issues
noted during review of logic. Also add some REVISIT comments for some issues noted in the design.
- boardctl: Remove the BOARDIOC_TSCTEST_TEARDOWN and
BOARDIOC_TSCTEST_SETUP boardctl() commands. Remove all
implementations of board_tsc_teardown(). Each board now initializes
the touchscreen controller as a normal part of its board bring-up.
board_tsc_setup() is gone; the touchscreen controller is now treated
like any other on-board device.
- configs: CONFIG_MAX_TASKS must be a power of 2.
- SMP: Introduce a new global IRQ clearing logic and tasklist
protection. The previous implementation of clearing global IRQ in
sched_addreadytorun() and sched_removereadytorun() was done too
early. As a result, nxsem_post() would have a chance to enter the
critical section even nxsem_wait() is still not in blocked state.
This patch moves clearing global IRQ controls from
sched_addreadytorun() and sched_removereadytorun() to
sched_resumescheduler() to ensure that nxsem_post() can enter the
critical section correctly. For this change,
sched_resumescheduler.c is always necessary for SMP configuration.
In addition, by this change, task_exit() had to be modified so that
it calls sched_resumescheduler() because it calls
sched_removescheduler() inside the function, otherwise it will cause
a deadlock. However, I encountered another DEBUGASSERT() in
sched_cpu_select() during HTTP streaming aging test on LC823450-XGEVK.
Actually sched_cpu_select() accesses the g_assignedtasks which might
be changed by another CPU. Similarly, other tasklists might be
modified simultaneously if both CPUs are executing scheduling logic.
To avoid this, I introduced tasklist protection APIs. With these
changes, SMP kernel stability has been much improved. From Masayuki
Ishikawa.
- SMP: Fix this_task() to be an atomic operation. In the previous
implementation, this_task() was defined in sched.h by using just a
macro current_task(this_cpu()). However, I found that this is not
atomic and actually sometimes switching CPU happened in executing
the macro when we tested audio steaming plus executing commands via
Telnet. This change resolves this issue by implementing atomic
this_task()in sched_thistask.c which is newly introduced. From
Masayuki Ishikawa.
- SMP: Implements a global scheduler lock capability as part of SMP
support. This allows the scheduler to be locked with no knowledge
or access to the TCB of the currently running task. This is
necessary because accessing the TCB of the currently running task
is, itself, a non-atomic operation. This global scheduler lock
capability was add just to support that atomic access to the TCB.
- SMP: Extend the last global lock change to work with the
LC823450-XGEVK which does not support the atomic fetch add but
does support disabling interprocessor interrupts. Disabling
interprocessor interrupts will also guarantee that the TCB address
calculation is atomic.
- SMP: Fix a infinite recursion problems that a recent changes
introduced into the i.MX6 SMP implementation. This is not seen
with the LC823450 because you can disable inter-processor interrupts
in that architecture; but you cannot in the ARMv7-A/GIC architecture.
- SMP: Remove SMP related logic in sig_dispatch.c. This change
prevents from a deadlock in up_schedulesigaction.c where inter-CPU
signal handling is actually implemented. arch/arm/src/armv7-m: Fix
signal handling for SMP. In previous implementation, signal handling
for SMP was incorrect. Thus, for example, if an inter-CPU signal
happened an incorrect tcb was signaled and caused ASSERT(). This
change fixes the issues and works for both inter-CPU signal handling
and signal handling on the same CPU. From Masayuki Ishikawa.
- Tasking: Add nxtask_create(). Kthread_create() and nxtask_create()
are internal OS functions and should not modify the errno variable.
Convert legitimate uses of task_create() to nxtask_create().
Review handling of returned values from all uses of kthread_create()
(as well as nxtask_create()).
- Tasking: Threads started by board bring-up logic should be kernel
threads, not user tasks.
- Tasking: Threads started by drivers should be kernel threads, not
user tasks.
- Semaphore Usage: Added ECANCELED condition to DEBUGASSERT's
checking sem_wait result From Dmitriy Linikov.
- errno: Add new internal OS function nxsched_setaffinity() that is
identical to sched_isetaffinity() except that it does not modify the
errno value. All usage of sched_setaffinity() within the OS is
replaced with nxsched_setaffinity().
- errno: Internal functions sched_reprioritize() and
sched_setpriority() no longer modify the errno value. Also renamed
to nxsched_reprioritize() and sched_setpriority().
- errno: Add new internal OS function nxsched_getscheduler() that is
identical to sched_getscheduler() except that it does not modify the
errno value. All usage of sched_getscheduler() within the OS is
replaced with nxsched_getscheduler().
- errno: Add new internal OS function nxsched_setparam() that is
identical to sched_setparam() except that it does not modify the
errno value. All usage of sched_setparam() within the OS is
replaced with nxsched_setparam().
- errno: Add new internal OS function nxsched_getparam() that is
identical to sched_getparam() except that it does not modify the
errno value (actually, the previous value erroneously neglected to
set the errno value to begin with, but this fixes both issues). All
usage of sched_getparam() within the OS is replaced with
nxsched_getparam().
- errno: wd_start() is an internal OS function and should not set the
errno value. Reviewed and updated every call to wd_start() to
verify if return value is used and if so if the errno value is
accessed.
- errno: Fix several inappropriate accesses to get_errno() that were
missed in previous changes (some going back to nuttx-7.23). Add new
nxsched_setscheduler() and nxsched_getaffinity() which are
equivalent to their counterparts without the nx on front. These
versions do not modify the errno value. Changed all calls within
the OS to use these newer versions of the functions.
- errno: binfmt/, configs/, grahics/, libc/, mm/, net/, sched/: OS
references to the errno variable should always use the set_errno(),
get_errno() macros.
- drivers/, fs/ and libc/: OS references to the errno variable should
always use the set_errno(), get_errno() macros.
* File System/Block and MTD Drivers:
- FAT: CONFIG_FAT_MAXFNAME may not exceed NAME_MAX (CONFIG_NAME_MAX)
- NFS: Correctly infer file type. The file type is in struct
nfs_statinfo_s's ns_type field, not in the ns_mode field. From
Michael Jung.
- NFS: Fix buffer corruption. In case multiple read requests to the
NFS server are required to fill up the user provided buffer,
nfs_read() might write behind the end of said buffer. This is fixed
with this change. From Michael Jung.
- VFS: reopen() should return NULL when oflags is less than 0, not
equal to 0. Because negative value is returned on failure of
lib_mode2offlags() which converts the mode string into file open
mode flag.
- ProcFS: Fix an error in a common function that manages read data.
- drivers/mmcsd: Respect SDIO_CAPS_DMABEFOREWRITE on CMD25. From
Evgeniy Bobkov.
- AT24xx: Correct page size for AT24C02 part. From Alexander
Oryshchenko.
- mtd_config.c: Add still more error handling (to detect bad
underlying flash implementations). Remove MTD_ERASE that was
erasing data block instead of erase block. This is a partial
revert of 4f18b4. Reported-by: Pascal Speck <iktek01@yahoo.com>
* Graphics/Display Drivers:
- drivers/lcd: Fix the default I2C address of SSD1306 OLED display
(7- vs 8-bit addressing) From Alan Carvalho de Assis.
- drivers/lcd: lcd_framebuffer.c does not need to include board-
specific board.h.
- include/lcd: Eliminate a warning from an SSD1306 header file by
adding a forward reference to struct i2c_master_s. From Sebastien
Lorquet.
* Networking/Network Drivers:
- ARP: Fix an error introduced when ICMP and ICMP6 socket support was
added in NuttX-7.3. A gratuitous ARP (or solicitation) was being
sent after receive of the ECHO replay (advertisement).
- ARP: Fix IGMP multicast address computation on Nuttx network stack.
This change fixes the IGMP address computation to allow multicast
UDP messages. The destination address was created with the incorrect
bytes of the given IPv4 address. From Louis Mayencourt.
- ioctl: The existence of the network driver ioctl() method should
depend on CONFIG_NETDEV_IOCTL rather than CONFIG_NETDEV_PHY_IOCTL.
The former enables the method, the later enables a subset of
possible driver IOCTLs.
- TCP: Write buffering logic should not wait for a free buffer if
the socket was opened non-blocking.
- TCP: Fixed bad return value handling in psock_tcp_send(). send()
expects psock_tcp_send() to return a negated errno value, not -1
with the errno set (GN: I added same change for tcp_send_buffered.c
which has the same issue as tcp_send_unbuffered.c) From Pelle
Windestam.
- TCP: Fixes hardfault when network goes done and network monitoring
is in place. From Gianpaolo Ferroni Ariani.
- TCP: tcp_send_[un]buffered.c: Check routing table in
psock_send_addrchck(). Previously only ARP table was considered
when determining if the data will actually be sent. From Juho
Grundstrom.
- TCP: Generalize Juho Grundstrom's IPv4 change for IPv6 as well.
- UDP: Remove some conditional logic that was true if there is only a
single network device, but not true in the multi-device context.
- UDP: In sendto(), return EHOSTUNREACH if the network is down.
* Common Drivers:
- drivers/pipes: In poll logic, fix off-by-one error in calculation
of bytes in the buffer. Buffer calculation in pipe poll setup is
off-by-one when read index is larger than write index. This causes
poll() not getting POLLIN when buffer has one byte as calculation
gives zero bytes in buffer. From Jussi Kivilinna.
- drivers/audio: Improve stability of the WM8776 driver in SMP mode.
Apply irq_spin APIs to improve performance. Repeat to process a
message to avoid deadlock. From Masayuki Ishikawa.
- drivers/ioexpander: Fixed build of PCF8574 driver when its
interrupts aren't enabled by config. From Dmitriy Linikov.
- drivers/syslog: Fixes LOG_UPTO macro to include specified log level.
From Anthony Merlino.
- drivers/sensors: Fix HTS221 sensor reset with BOOT bit From Jussi
Kivilinna.
- drivers/loop: If we want to open read-only in losetup.c, flags
should be O_RDONLY not O_RDWR. From Fabio D'Urso.
- drivers/timers/ds3231.c: Correct some debug statements. From
Alexander Oryshchenko.
- drivers/sensors/lis2dh: Use realtime clock if monotonic is not
available From Juha Niskanen.
- drivers/i2c and drivers/spi: Fix compile error if
CONFIG_DISABLE_PSEUDOFS_OPERATIONS, fix bad NULL checks From Juha
Niskanen.
* ARMv7-A:
- Data Cache: Fix cp15_invalidate_dcache. In cases where more than
one dcache line was to be invalidated, a missing branch label
would result in a false branch target into cp15_flush_idcache. Also
the .size macro was fixed for both cp15_invalidate_dcache. From
Michael Jung.
- SMP: Port the signal-related SMP change by Masayuki Ishikawa to the
ARMv7-A family.
* Extensa:
- SMP: Port the signal-related SMP change by Masayuki Ishikawa to the
Xtensa family.
* Infineon XMC4xxx Drivers:
- XMC4xxx: Only setup USB clock when USB PLL is enabled From Alan
Carvalho de Assis.
- XMC4xxx: Fix USIC_BRG_SCLKCFG definition From Alan Carvalho
de Assis.
* Microchip PIC32MZ
- MIPS32: In up_idle, the kludge that was conditionally enabled if
the work queue was enable appears to be needed even when he work
queue is not enabled on the PIC32MZ.
- PIC32MZ: Fix some typos in debug instrumentation in pic32mz-gpio.c;
fix some typos related to UART5 configuration in pic32mz-serial.c.
* Microchip/Atmel SAMD/L:
- SPI: In sam_spibus_initialize(), the pinmux configuration was
smashing the previous CTRLA register configuration. There are
also some typos in samd_spi.h From Matt Thompson.
- SPI: Fixes g_spi2ops and g_spi2dev using incorrect values From Matt
Thompson.
- SPI: SPI must be disabled before changing the mode bits in CTRLA
register From Matt Thompson.
- DMA: Fix DMA controller support. From Matt Thompson.
* NXP/Freescale LPC17xx Drivers:
- LPC17xx: Disable LPC17 FDR when not used. If a boot loader set the
fractional divider (FDR) the baud rate in nuttx will be wrong
(multiplied by this fraction). So if it is not used, it should be
disabled. From Harald Gutsche.
* NXP/Freescale Kinetis Drivers:
- Kinetis: Correct some Ethernet PHY register bit tests for the
KSZ8081 PHY. From Stewart.
* On Semiconductor LC823450
- arch/arm/src/LC823450: Add SP_DMB() into lc823450_testset.c.
In LC823450, ldrex and strex are not supported. So we implemented
up_testset() with H/W Mutex. However, there was a bug in memory
access order. This change ensures correct memory access order in
up_testset() for LC823450. From Masatoshi Tateishi.
* STMicro STM32 Drivers:
- STM32 F3 RCC: A flash wait state configuration. Flash latency must
be fixed according to sysclk frequency. If this operation is not
done or done after PLL configuration, the STM32 fail to continue
boot operation if the frequency if greater than 24MHz according to
the board variable STM32_SYSCLK_FREQUENCY. Tested on stm32f334-disco
board. From Gwenhael Goavec-Merou.
- STM32 RTC: Make STM32 usable with an external RTC.
- STM32 SPI: Removed unnecessary (and incorrect) speed limitation.
From Alexander Oryshchenko.
- STM32 SPI: I have a SPI bus with both Mode 0 and Mode 3 devices
on it. After performing SPI I/O to a Mode 0 device, switching to a
Mode 3 device locked up the SPI interface. Only zeroes would be
read. I traced the reason for the lock-up to arm/arm/src/stm32f7/stm32_spi.c function spi_setmode(). Changing
the mode causes a spurious SPI clock transmission that confuses the
stm32f7 SPI input hardware. This problem is solved by (1) changing
the SPI mode with SPI (and perhaps DMA) disabled, and (2) flushing
the receive FIFO if the mode change results in garbage in the FIFO.
From Bob Feretich.
- STM32 and STM32 F7: Remove confusing, redundant, and misleading
definitions of STM32_BKP_BASE from the F2, F3, and F4 memory
maps. Unlike the F1, these parts do not have a separate BKP address
region. The BKP registers are with the RTCC address regions.
stm32_bkp.h should only be used for STM32 F1. stm32_rtcc.h should be
used to access BKP registers on F2, F3, and F4.
- STM32 and STM32 F7: Architecture-specific code is not permitted to
modify the errno variable.
- STM32 F4 I2C: Correct some recent changes to STM32F4 I2C that broke
poll mode of operation. From Alexander Oryshchenko.
- STM32 F4 I2C: Corrections to STM32 F4 I2C to restore functionality.
From Alexander Oryshchenko.
- STM32 F4 I2C: Corrections to STM32 F4 I2C to fix the NORESTART
flag. From Alexander Oryshchenko.
- STM32 F7: Fixes a bug in multi-block SD-card operations on the
STM32F7 platform. DBLOCKSIZE must be the size of SD-card block, not
the total amount of transferred bytes. From Evgeniy Bobkov.
- STM32 F7: Fix undefined variable when using USART1 for other
purposes than UART (e.g. SPI). From Frank Benkert.
- STM32 F7: Backport RTC alarm setting changes from STM32L4. Most
notably this fixes RTC getting stuck issue when both alarms were
used. Root cause was writing RTC ISR register contents to RTC CR
register. From Juha Niskanen.
- STM32 L4 Flash: Change flash programming to use page buffer for
unaligned writes. From Juha Niskanen.
* STMicro STM32 Boards:
- Nucleo-L432KC: Fix some bogus logic noted by Fanda.
- configs/nucleo-* and configs/stm32l476vg-disco: Fix more
stm32_userleds.c bogus logic From Juha Niskanen.
- Nucleo-L432KC: Fixed nucleo-l432kc broken build when
CONFIG_USERLED_LOWER defined From Fanda.
- Nucleo-L432KC: Issue #85: /dev/userleds is not working for
Nucleo-L432KC fixed From Fanda Vacek.
- STM32F429I-Disco: Separate SPI4 from MTD init. I was trying to
attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4
port and was hitting compilation problems, since CONFIG_MTD and
thus 'struct mtd_geometry_s' was not defined. This patch separates
SPI4 initialization logic from MTD initialization logic. From
Michael Jung.
- STM32F103-Minimum: Remove CONFIG_NX_LCDDRIVER dependence from
stm32_ssd1306.c From Alan Carvalho de Assis.
* C Library/Header Files:
- libc/stdio: In dtoa(), up_interrupt_context() is used in a debug
assertion. up_interrupt_context() is not available in the user-mode
phase of the PROTECTED or KERNEL build configurations. In those
configurations, enabling libc floating point support and debug
assertions will result in an undefined reference to
up_interrupt_context().
- libc/netdb: Fixed parsing of DNS response packets having compressed
names ending with pointer. There were troubles parsing response
packets which have compression of QNAME/NAME field when only
trailing part of the name (not the whole name) is replaced with
pointer to another part of the packet. This commit fixes parsing of
such packets. Also I added checks to keep parsing only in bounds of
the read part of DNS response packet. From Dmitriy Linikov.
* Tools
- tools/*.c: Add #define _GNU_SOURCE to all C files that call
asprintf() to eliminate a warning.
- tools/cvsparser.c: Add a check to avoid access past the end
of a fixed size array
* NSH: apps/nshlib:
- apps/nshlib: Fix compile error when CONFIG_NSH_DISABLESCRIPT is not
defined. The field np_flags does not exist if scripting is disabled.
* Examples/Tests: apps/examples:
- apps/examples/touchscreen: Eliminate BOARDIOC_TSCTEST_SETUP.
* Network Utilities: apps/netutils:
- apps/netutils/ftpc: Fix some corner-cases that could cause FTP to
access past the end of valid data.
* Wireless Utilities: apps/wireless:
- apps/wireless/ieee802154/i8shark: Fixes special XBee compensation
by purposely chopping off the FCS. From Anthony Merlino.
