should be brought into a critical section (suggested by Mike Smith)
|
|
|
|
|
* sched/sched_setuptaskfiles.c: Should be 'struct socket' not
|
|
|
|
|
'struct sockets'. How did this compile before? (found by Kate)
|
|
|
|
|
* syscall/syscall.csv: Fix prototype for usleep() and prctl() (also
|
|
|
|
|
from Kate).
|
|
|
|
|
* arch/arm/src/lpc17xx/lpc17_ethernet.c: Conditionally elide setting PHY
|
|
|
|
|
speed/duplex. This does not work for certain PHYs. Still some unresolved
|
|
|
|
|
issues (also from Kate).
|
|
|
|
|
* tools/Config.mk, Makefile, configs/*/Make.defs: Add a new Makefile
|
|
|
|
|
fragment to de-quote certain strings from the Kconfig logic that
|
|
|
|
|
need to be used at path segments (Richard Cochran).
|
|
|
|
|
* arch/arm/src/stm32/stm32_usbotghost.c: The STM32 USB host driver only
|
|
|
|
|
works with debug turned on. The problem appears to be that with debug
|
|
|
|
|
OFF, there are more NAKs occuring in more places than before and this
|
|
|
|
|
reveals a variety of errors. This check in improves NAK robustness
|
|
|
|
|
for control transfers but does not resolve all of the issues.
|
|
|
|
|
* configs/stm3220g-eval/*/defconfig: Calibrated delay loop. It had
|
|
|
|
|
never been calibrated was way off.
|
|
|
|
|
* sched/sem_holder.c: Add logic to handler some priority inheritance
|
|
|
|
|
cases when sem_post() is called from an interrupt handler. The
|
|
|
|
|
logic is clearly wrong, but it is not known if this is the
|
|
|
|
|
cause of any known bugs.
|
|
|
|
|
* lib/stdio/lib_perror(): Add perror(). Contributed by Kate.
|
|
|
|
|
* lib/string/lib_strerror(): Add option CONFIG_LIBC_STRERROR that
|
|
|
|
|
is now required to enabled strerror(). Add an option
|
|
|
|
|
CONFIG_LIBC_STRERROR_SHORT that can be used to output shortened
|
|
|
|
|
strings by strerror().
|
|
|
|
|
* arch/arm/src/stm32/stm32_usbotghost.c: Finally... the USB OTG FS
|
|
|
|
|
appears to handle NAKing correctly.
|
|
|
|
|
* configs/stm32f4discovery/*: Added and verifed support for USB OTG FS
|
|
|
|
|
host on the STM32F4Discovery board.
|
|
|
|
|
* configs/*/defconfig: Remove configuration documentation from config
|
|
|
|
|
files. It is redundant, error-prone, and difficult to maintain.
|
|
|
|
|
Configuration documentation is available in configs/README.txt for
|
|
|
|
|
common configurations and in configs/*/README.txt for board and MCU-
|
|
|
|
|
specific configurations.
|
|
|
|
|
* configs/stm3240g-eval: Add USB host support.
|
|
|
|
|
* sched/os_bring.c, configs/*/defconfig, tools/mkconfig.c, and others: Added
|
|
|
|
|
configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
|
|
|
|
|
the default entry from user_start to some other symbol. Contributed by
|
|
|
|
|
Kate. NOTE: This change does introduce a minor backward incompatibility.
|
|
|
|
|
For example, if your application uses NSH as its start-up program, then your
|
|
|
|
|
build will now fail because it will be unable to find "user_start". The fix
|
|
|
|
|
for this link failure is to add the following to your configuration file:
|
|
|
|
|
CONFIG_USER_ENTRYPOINT="nsh_main".
|
|
|
|
|
* libs/stdio/lib_libfread.c and lib_*flush*.c: Correct a couple of
|
|
|
|
|
error cases where the lib semaphore was not be released on error
|
|
|
|
|
exits (thanks Ronen Vainish). Also, improved some error reporting:
|
|
|
|
|
the generic ERROR was being used instead of the specific errno
|
|
|
|
|
value; the errno variable was not always set correctly.
|
|
|
|
|
* tools/mkfsdata.pl: The uIP web server CGI image making perl script was
|
|
|
|
|
moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
|
|
|
|
|
(Part of a larger change submitted by Max Holtzberg).
|
|
|
|
|
* configs/stm3240g-eval/script/ld.script: All of the identical ld.script
|
|
|
|
|
files for the STM3240G-EVAL were replaced by one version in this directory.
|
|
|
|
|
* configs/stm3240g-eval/webserver: Configuration submitted by Max Holtzberg
|
|
|
|
|
for testing the changes to the uIP web server (see apps/ChangeLog.txt).
|
|
|
|
|
* lib/stdio/lib_perror.c: Remove CONFIG_LIBC_PERROR_DEVNAME. What was I
|
|
|
|
|
thinking? Arbitrary streams cannot be shared by different tasks.
|
|
|
|
|
* tools/mksyscall.c, csvparser.c, and csvparser.h: Separate CSV parsing
|
|
|
|
|
logic from mksyscall.c into files where it can be shared.
|
|
|
|
|
* tools/mksymtab.c: Add a tool that can be used to convert a CSV file
|
|
|
|
|
into a NuttX-style symbol table.
|
|
|
|
|
* sched/work_cancel.c: Fix a bad assertion (reported by Mike Smith)
|
|
|
|
|
* configs/stm3210e-eval/src/up_idle.c: Correct some power management
|
|
|
|
|
compilation errors (reported by Diego Sanchez).
|
|
|
|
|
* include/nuttx/wqueue.h, sched/work*, and others: Added logic to support
|
|
|
|
|
a second, lower priority work queue (CONFIG_SCHED_LPWORK).
|
|
|
|
|
* arch/arm/src/stm32/stm32_dma.c, chip/stm32*_memorymap.h: FSMC SRAM is
|
|
|
|
|
only 16-bits wide and the SDIO DMA must be set up differently.
|
|
|
|
|
* arch/arm/src/stm32/stm32_dma.c: Back out the 16-bit DMA change. It
|
|
|
|
|
is incorrect.
|
|
|
|
|
* configs/: Make use of UART4/5 vs USART4/5 consistent in all places.
|
|
|
|
|
* Kconfig: Serial 2STOP setting must be integer 0/1, not a boolean.
|
|
|
|
|
* lib/misc/sendfile.c and include/sys/sendfile.h: Add a Linux style
|
|
|
|
|
sendfile() (non-standard!)
|
|
|
|
|
* Kconfig: Refactor serial settings (moved from chip to drivers/serial).
|
|
|
|
|
AVR "teensy" now builds with Kconfig (contributed by Richard Cochran).
|
|
|
|
|
* Kconfig: Add configuration settings for the LPC17xx
|
|
|
|
|
* Kconfig: Add configuration settings for the LM3S (from Richard Cochran).
|
|
|
|
|
* Kconfig: Verify configuration settings for the STM32. This includes
|
|
|
|
|
changes in the way that the external SRAM is configured: Define
|
|
|
|
|
CONFIG_HEAP2_SIZE (decimal) instead of CONFIG_HEAP2_END (hex).
|
|
|
|
|
* tools/configure.sh: Don't append the apps directory path setting
|
|
|
|
|
if the correct setting is already in defined in the defconfig file.
|
|
|
|
|
* fs/fat/fs_utils.c: Improperly constructed bool expression. This
|
|
|
|
|
would cause many unnecessary writes to FLASH (Thanks Ronen Vainish).
|
|
|
|
|
* Kconfig: Verify configuration settings for the LPC43xx. This includes
|
|
|
|
|
some corrections to configuration variable names and defconfig settings.
|
|
|
|
|
* Kconfig: Add and verify configuration settings for the LPC31xx.
|
|
|
|
|
* arch/arm/src/stm32/stm32_uart.h and stm32_serial.c: Add logic to
|
|
|
|
|
re-initialize the console UART as needed to enable DMA on the
|
|
|
|
|
console UART (contributed by Mike Smith).
|
|
|
|
|
* net/recvfrom.c, net/Kconfig, include/nuttx/net/uipopt.h: Remove delay
|
|
|
|
|
after receiving data. That has historical reasons to be there (it
|
|
|
|
|
was needed before read-ahead buffering was added), but kills performance.
|
|
|
|
|
(Noted by Max Holtzberg).
|
|
|
|
|
* configs/shenzhou: Add beginnings of a board configuration for the
|
|
|
|
|
Shenzhou STM32107 board (see www.armjishu.com). Very little is in
|
|
|
|
|
place as of this initial check-in.
|
|
|
|
|
* QEMU: Fixes from Richard Cochran to build QEMU with Kconfig files.
|
|
|
|
|
* arch/*/src/Makefile: Remove some old logic that was kicked off
|
|
|
|
|
when CONFIG_BOOT_RUNFROMFLASH=y. The old logic used to use
|
|
|
|
|
objcopy to move sections. Newer logic changes the load position
|
|
|
|
|
of sections in the the linker script. As far as I can tell, there
|
|
|
|
|
is nothing in the source tree now that depends on the old way of
|
|
|
|
|
doing things (if I am wrong, they will need a change to the linker
|
|
|
|
|
script).
|
|
|
|
|
* configs/fire-stm32v2: Configuration for the M3 Wildfire board. I
|
|
|
|
|
don't know very much about this board other than is has an
|
|
|
|
|
STM32F103VET6 chip, LCD, touchscreen, and ENC28J60 network. Very
|
|
|
|
|
little is in place on the initial check-in.
|
|
|
|
|
* configs/shenzhou: Coding for the Shenzhou board port is complete,
|
|
|
|
|
but tested has been deferred until I get the right tools.
|
|
|
|
|
* arch/arc/include/stm32/chip.h and arch/arm/src/stm32/chip.h:
|
|
|
|
|
Add support for the STM32F103VET6.
|
|
|
|
|
* fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted
|
|
|
|
|
by Ronen Vainish).
|
|
|
|
|
* drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever
|
|
|
|
|
uninitialized then there would be a double release of memory
|
|
|
|
|
(Noted by Ronen Vainish).
|
|
|
|
|
* fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed
|
|
|
|
|
by Kate).
|
|
|
|
|
* arch/avr/src: Fixes from AVR32 build errors that have crept in
|
|
|
|
|
over the time; incorporated Kconfig for AVR3 (Richard Cochran).
|
|
|
|
|
* fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates
|
|
|
|
|
memory for sector I/O buffers used to exchange data with the
|
|
|
|
|
configured block driver. In some contexts, the block driver may
|
|
|
|
|
require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined,
|
|
|
|
|
then the FAT FS will use platform-provided DMA memory allocators
|
|
|
|
|
to allocate the block driver I/O buffers.
|
|
|
|
|
* CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent
|
|
|
|
|
in all places.
|
|
|
|
|
* drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and
|
|
|
|
|
olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number
|
|
|
|
|
as a parameter. Instead now passes a call table to manage
|
|
|
|
|
ENC28J60 GPIO interrupts. That is because GPIO interrupts are
|
|
|
|
|
handled in different ways by different MCUs and some do not
|
|
|
|
|
support IRQ numbers for GPIO interrupts.
|
|
|
|
|
* mm/mm_gran* and include/nuttx/gran.h: Add a simple granule-
|
|
|
|
|
based allocator. The intent of this allocator is to support
|
|
|
|
|
simple allocation of DMA I/O buffers. The initial check-in
|
|
|
|
|
is code complete but untested (not event built into the
|
|
|
|
|
mm/Makefile yet.
|
|
|
|
|
* confgs/fire-stm32v2: The board port is basically functional.
|
|
|
|
|
Not all features have been verified. The ENC28J60 network
|
|
|
|
|
is not yet functional.
|
|
|
|
|
* configs/stm3240g-eval/discover: A configuration for testing
|
|
|
|
|
the UDP discovery utility. Contributed by Max Holtzberg.
|
|
|
|
|
* mm/README.txt: Add a new README file.
|
|
|
|
|
* include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c:
|
|
|
|
|
Add hooks to to use common, external DMA buffer allocation
|
|
|
|
|
implementation.
|
|
|
|
|
* net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering
|
|
|
|
|
is enabled and (2) some data was obtained from read-ahead buffers.
|
|
|
|
|
Blocking is a bad idea in that case because there is no timeout!
|
|
|
|
|
(submitted by Max Holtzberg).
|
|
|
|
|
* configs/stm3240g-eval/xmlrpc: An example configuration for the
|
|
|
|
|
Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc.
|
|
|
|
|
See http://www.drdobbs.com/web-development/\

|
|
|
|
|
* configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for
|
|
|
|
|
bugs that crept in during recent changes. (Submitted by Max
|
|
|
|
|
Holtzberg).
|
|
|
|
|
* arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave().
|
|
|
|
|
It looks like sometimes the compile will re-order some instructions
|
|
|
|
|
inapproapriately. This end result is that interrupts will get
|
|
|
|
|
stuck off.
|
|
|
|
|
* drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI
|
|
|
|
|
FLASH family (W25x16, W25x32, and W25x64). The initial check-in
|
|
|
|
|
is basically just the SST25 driver with some name changes.
|
|
|
|
|
* arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c:
|
|
|
|
|
Back out the last change in irq.h. It is (most likely) fine the
|
|
|
|
|
way it was. The really interrupt related problem was in stm32_spi.c:
|
|
|
|
|
When SPI3 is not enabled, then the irqrestore() falls in the
|
|
|
|
|
else clause.
|
|
|
|
|
* include/nuttx/compiler.h and other files: Moved always_inline
|
|
|
|
|
and noinline __attributes__ here. Also replaced all occurrences
|
|
|
|
|
of explicit __atributes__ in other files with definitions from
|
|
|
|
|
this header file.
|
|
|
|
|
* drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is
|
|
|
|
|
code complete (but still untested).
|
|
|
|
|
* arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith.
|
|
|
|
|
Unified configuration logic; dynamic timeout calculations;
|
|
|
|
|
I2C reset logic to recover from locked devices on the bus.
|
|
|
|
|
* configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all
|
|
|
|
|
common make definitions from the various Make.defs files into
|
|
|
|
|
the common tools/Config.mk. Add support for a verbosity options:
|
|
|
|
|
Specify V=1 on the make command line in order to see the exact
|
|
|
|
|
commands used in the build (Contributed by Richard Cochran).
|
|
|
|
|
* drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is
|
|
|
|
|
now functional.
|
|
|
|
|
* configs/fire-stm32v2: Add support or the fire-stm32v3 board as
|
|
|
|
|
well (untested because I do not have a v3 board).
|
|
|
|
|
* lib/stdio/lib_sscanf.c: Add %n psuedo-format (from Kate).
|
|
|
|
|
* lib/stdio/lib_sscanf.c: There is an issue of handling input
|
|
|
|
|
when (1) no fieldwidth is provided and (2) there is no space
|
|
|
|
|
seperating the input values. No solutions is in place for this
|
|
|
|
|
case now (either space or a fieldwidth must be provided). But
|
|
|
|
|
at least some of the bad logic that attempted to handle this
|
|
|
|
|
case has been removed (noted by Kate).
|
|
|
|
|
* arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an
|
|
|
|
|
even multiple of 4, 8, or 16 bytes.
|
|
|
|
|
* arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues:
|
|
|
|
|
We cannot go into sleep mode while Ethernet is actively DMAing.
|
|
|
|
|
* configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support
|
|
|
|
|
SSD1289 LCD. Initial checkin is just a clone of the
|
|
|
|
|
STM32F4Discovery's FSMC-based LCD interface. The Shenzhou
|
|
|
|
|
will need a completely need bit-banging interface; this
|
|
|
|
|
initial check-in is only for the framework.
|
|
|
|
|
* configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is
|
|
|
|
|
code complete.
|
|
|
|
|
* configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not
|
|
|
|
|
have an SSD1289 controller. Its an ILI93xx. Ported the
|
|
|
|
|
STM3240G-EVAL ILI93xx driver to work on the Shenzhou board.
|
|
|
|
|
* configs/shenzhou/nxwm: Added an NxWM configuration for the
|
|
|
|
|
Shenzhou board. This is untested on initial check-in. It will
|
|
|
|
|
be used to verify the Shenzhou LCD driver (and eventually the
|
|
|
|
|
touchscreen driver).
|
|
|
|
|
* configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen
|
|
|
|
|
support for the Shenzhou board. The initial check-in is untested
|
|
|
|
|
and basically a clone of the the touchscreen support for the SAM-3U.
|
|
|
|
|
* tools/cfgparser.c: There are some NxWidget configuration
|
|
|
|
|
settings that must be de-quoted.
|
|
|
|
|
* arch/arm/src/stm32/Kconfig: There is no SPI4. Some platforms
|
|
|
|
|
support SPI3 and some do not (still not clear).
|
|
|
|
|
* nuttx/configs/shenzhou: Various fixes to build new NxWM
|
|
|
|
|
configuration.
|
|
|
|
|
* configs/shenzhou: Oops. The Shenzhou LCD is and SSD1289,
|
|
|
|
|
not an ILI93xx.
|
|
|
|
|
* configs/shenzhou/src/up_ssd1289.c: The LCD is basically functional
|
|
|
|
|
on the Shenzhou board.
|
|
|
|
|
* graphics/nxmu: Correct some bad parameter checking that caused
|
|
|
|
|
failures when DEBUG was enabled.
|
|
|
|
|
* arch/arm/src/armv7-m/nvic.h: Add bit definitions for the AIRCR
|
|
|
|
|
register.
|
|
|
|
|
* drivers/input/ads7843.c: Need semaphore protection in logic
|
|
|
|
|
that samples the position.
|
|
|
|
|
* drivers/lcd/ssd1289.c: On some platforms we are unable to
|
|
|
|
|
read the device ID -- reason unknown; workaround in place.
|
|
|
|
|
* drivers/input/ads7843.c: Add thresholding options and an
|
|
|
|
|
option to swap X and Y positions. Fix some logic errors in
|
|
|
|
|
the SPI locking/selecting logic.
|
|
|
|
|
* arch/arm/src/armv7-m/up_systemreset.c: Add logic to reset
|
|
|
|
|
the Cortex-Mx using the AIRCR register. Contributed by Darcy
|
|
|
|
|
Gong.
|
|
|
|
|
* arch/arm/src/stm32/up_eth.c: Add logic specifically for the
|
|
|
|
|
DM9161 PHY. If the DM9161 failed to initialize, then use the
|
|
|
|
|
up_sysemreset() logic to reset the MCU. Contributed by Darcy
|
|
|
|

Gong.
|
|
|

for SPI3 remap. This fixes the XPT2046 touchscreen driver using
|
|
|
|
|
drivers/input/ads7843.c
|
|
|
|
|
* configs/shenzhou/src/up_ssd1289.c: Fix naming error in
|
|
|
|
|
conditional compilation.
|
|
|
|
|
* configs/shenzhou/nxwm/defconfig: Disable reading from the LCD.
|
|
|
|
|
This does not work. The hardware and the driver support the
|
|
|
|
|
capability, but there is some bug that causes memory corruption.
|
|
|
|
|
The work around for now: Just disable reading from the LCD.
|
|
|
|
|
* drivers/lcd/ssd1289.c: Add some logic to reduce the amount of
|
|
|
|
|
output when CONFIG_DEBUG_LCD is enabled.
|
|
|
|
|
* configs/shenzhou/nxwm/defconfig: Bug found and fixed... The
|
|
|
|
|
original configuration had too much stuff turned on. Reducing
|
|
|
|
|
stack sizes, some features, and buffer sizes made the
|
|
|
|
|
configuration reliable (Reading from the LCD is still disabled).
|
|
|
|
|
* net/uip/uip_icmpping.c: Fix problem that prevented ping from
|
|
|
|
|
going outside of local network. Submitted by Darcy Gong
|
|
|
|
|
* arch/arm/src/stm32/stm32_rng.c, chip/stm32_rng.h, and other files:
|
|
|
|
|
Implementation of /dev/random using the STM32 Random Number
|
|
|
|
|
Generator (RNG).
|
|
|
|
|
* board.h file for shenzhou, fire-stm32v2, and olimex-stm32-p107:
|
|
|
|
|
Add frequencies for HSE, HSI, LSE, and LSI. These are needed
|
|
|
|
|
by the STM32 watchdog driver.
|
|
|
|
|
* CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
|
|
|
|
|
of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.
|
|
|
|
|
* drivers/mtd/w25.c and configs/*/src/up_w25.c: Several fixes for the
|
|
|
|
|
W25 SPI FLASH.
|
|
|
|
|
* configs/*/Make.defs: All buildroot tools now use the extension
|
|
|
|
|
xxx-nuttx-elf- vs. xxx-elf-
|
|
|
|
|
* configs/shenzhou/*/Make.defs: Now uses the new buildroot 4.6.3
|
|
|
|
|
EABI toolchain.
|
|
|
|
|
* lib/stdio/lib_libdtoa.c: Another dtoa() fix from Mike Smith.
|
|
|
|
|
* configs/shenzhou/src/up_adc.c: Add ADC support for the Shenzhou
|
|
|
|
|
board (Darcy Gong).
|
|
|
|
|
* configs/shenzhou/thttpd: Add a THTTPD configuration for the
|
|
|
|
|
Shenzhou board (Darcy Gong).
|
|
|
|
|
* include/termios.h and lib/termios/libcf*speed.c: The non-standard,
|
|
|
|
|
"hidden" c_speed cannot be type const or else static instantiations
|
|
|
|
|
of termios will be required to initialize it (Mike Smith).
|
|
|
|
|
* drivers/input/max11802.c/h, and include/nuttx/input max11802.h: Adds
|
|
|
|
|
support for the Maxim MAX11802 touchscreen controller (contributed by
|
|
|
|
|
Petteri Aimonen).
|
|
|
|
|
* graphics/nxtk/nxtk_events.c: Missing implementatin of the blocked
|
|
|
|
|
method. This is a critical bugfix for graphics support (contributed
|
|
|
|
|
by Petteri Aimonen).
|
|
|
|
|
* drivers/usbdev/pl2303.c, drivers/usbdev/usbmsc.h, and
|
|
|
|
|
include/nuttx/usb/cdcacm.h: USB_CONFIG_ATTR_SELFPOWER vs.
|
|
|
|
|
USB_CONFIG_ATT_SELFPOWER (contributed by Petteri Aimonen).
|
|
|
|
|
* arch/arm/src/armv7-m/up_memcpy.S: An optimized memcpy() function for
|
|
|
|
|
the ARMv7-M family contributed by Mike Smith.
|
|
|
|
|
* lib/strings/lib_vikmemcpy.c: As an option, the larger but faster
|
|
|
|
|
implemementation of memcpy from Daniel Vik is now available (this is
|
|
|
|
|
from http://www.danielvik.com/2010/02/fast-memcpy-in-c.html).
|
|
|
|
|
* lib/strings/lib_memset.c: CONFIG_MEMSET_OPTSPEED will select a
|
|
|
|
|
version of memset() optimized for speed. By default, memset() is
|
|
|
|
|
optimized for size.
|
|
|
|
|
* lib/strings/lib_memset.c: CONFIG_MEMSET_64BIT will perform 64-bit
|
|
|
|
|
aligned memset() operations.
|
|
|
|
|
* arch/arm/src/stm32/stm32_adc.c: Need to put the ADC back into the
|
|
|
|
|
initial reset in the open/setup logic. Opening the ADC driver works
|
|
|
|
|
the first time, but not the second because the device is left in a
|
|
|
|
|
powered down state on the last close.
|
|
|
|
|
* configs/olimex-lpc1766stck/scripts: Replace all of the identical
|
|
|
|
|
ld.script files with the common one in this directory.
|
|
|
|
|
* configs/stm3220g-eval/scripts: Replace all of the identical
|
|
|
|
|
ld.script files with the common one in this directory.
|
|
|
|
|
* configs/hymini-stm32v/scripts: Replace all of the identical
|
|
|
|
|
ld.script files with the common one in this directory.
|
|
|
|
|
* configs/lpcxpresso-lpc1768/scripts: Replace all of the identical
|
|
|
|
|
ld.script files with the common one in this directory.
|
|
|
|
|
* binfmt/elf.c, binfmt/libelf, include/elf.h, include/nuttx/elf.h: Add
|
|
|
|
|
basic framework for loadable ELF module support. The initial check-
|
|
|
|
|
in is non-functional and is simply the framework for ELF support.
|
|
|
|
|
* include/nuttx/binfmt.h, nxflat.h, elf.h, and symtab.h: Moved to
|
|
|
|
|
include/nuttx/binfmt/.
|
|
|
|
|
* arch/sim/src/up_elf.c and arch/x86/src/common/up_elf.c: Add
|
|
|
|
|
for ELF modules.
|
|
|
|
|
* arch/arm/include/elf.h: Added ARM ELF header file.
|
|
|
|
|
* include/elf32.h: Renamed elf.h to elf32.h.
|
|
|
|
|
* configs/stm32f4discovery/ostest: Converted to use the new
|
|
|
|
|
Kconfig-based configuration system.
|
|
|
|
|
* configs/stm32f4discovery/elf and configs/stm32f4discovery/scripts/gnu-elf.ld
|
|
|
|
|
Add a configuration for testing the ARM ELF loader.
|
|
|
|
|
* binfmt/libelf: Can't use fstat(). NuttX does not yet support it. Damn!
|
|
|
|
|
* binfmt/libelf: The basic ELF module execution appears fully functional.
|
|
|
|
|
* configs/shenzhou/src/up_relays.c: Add support for relays from the
|
|
|
|
|
Shenzhou board. Contributed by Darcy Gong.
|
|
|
|
|
* lib/fixedmath: Moved the old lib/math to lib/fixedmath to make room for
|
|
|
|
|
the math library from the Rhombus OS
|
|
|
|
|
* lib/math: Now contains the math library from the Rhombus OS by Nick Johnson
|
|
|
|
|
(submitted by Darcy Gong).
|
|
|
|
|
* include/float.h: Add a first cut at the float.h header file. This
|
|
|
|
|
really should be an architecture/toolchain-specific header file. It
|
|
|
|
|
is only used if CONFIG_ARCH_FLOAT_H is defined.
|
|
|
|
|
* lib/math: Files now conform to coding standards. Separated float,
|
|
|
|
|
double, and long double versions of code into separate files so that
|
|
|
|
|
they don't draw in so much un-necessary code when doing a dumb link.
|
|
|
|
|
* binfmt/libelf: The ELF loader is working correctly with C++ static
|
|
|
|
|
constructors and destructors and all.
|
|
|
|
|
* Documentation/NuttXBinfmt.html: Add documentionof the binary loader.
|
|
|
|
|
* configs/sim/ostest: Converted to use the mconfig configuration tool.
|
|
|
|
|
* configs/sim/cxxtest: New test that will be used to verify the uClibc++
|
|
|
|
|
port (eventually).
|
|
|
|
|
* include/nuttx/fs/fs.h, lib/stdio/lib_libfread.c, lib_ferror.c,
|
|
|
|
|
lib_feof.c, and lib_clearerr.c: Add support for ferror(), feof(),
|
|
|
|
|
and clearerror(). ferror() support is bogus at the moment (it
|
|
|
|
|
is equivalent to !feof()); the others should be good.
|
|
|
|
|
* configs/stm32f4discovery/include/board.h: Correct timer 2-7
|
|
|
|
|
base frequency (provided by Freddie Chopin).
|
|
|
|
|
* include/nuttx/sched.h, sched/atexit.c, and sched/task_deletehook.c:
|
|
|
|
|
If both atexit() and on_exit() are enabled, then implement atexit()
|
|
|
|
|
as just a special caseof on_exit(). This assumes that the ABI can
|
|
|
|
|
handle receipt of more call parameters than the receiving function
|
|
|
|
|
expects. That is usually the case if parameters are passed in
|
|
|
|
|
registers.
|
|
|
|
|
* libxx/libxx_cxa_atexit(): Implements __cxa_atexit()
|
|
|
|
|
* configs/stm32f4discovery/cxxtest: New test that will be used to
|
|
|
|
|
verify the uClibc++ port (eventually). The sim platform turned not
|
|
|
|
|
to be a good platform for testing uClibc++. The sim example will not
|
|
|
|
|
run because the simulator will attempt to execute the static
|
|
|
|
|
constructors before main() starts. BUT... NuttX is not initialized
|
|
|
|
|
and this results in a crash. On the STM324Discovery, I will have
|
|
|
|
|
better control over when the static constructors run.
|
|
|
|
|
* RGMP 4.0 updated from Qiany Yu.
|
|
|
|
|
* configs/*/Make.defs and configs/*/ld.script: Massive clean-up
|
|
|
|
|
and standardization of linker scripts from Freddie Chopin.
|
|
|
|
|
* net/netdev_ioctl.c: Add interface state flags and ioctl calls
|
|
|
|
|
to bring network interfaces up and down (from Darcy Gong).
|
|
|
|
|
* config/stm32f4discovery: Enable C++ exceptions. Now the entire
|
|
|
|
|
apps/examples/cxxtest works -- meaning the the uClibc++ is
|
|
|
|
|
complete and verified for the STM32 platform.

|
|
|
|
|
list (contributed by Kate).
|
|
|
|
|
* apps/nshlib/nsh_parse.c: CONFIG_NSH_DISABLE_WGET not CONFIG_NSH_DISABLE_GET
|
|
|
|
|
in one location (found by Kate).
|
|
|
|
|
* apps/examples/ostest/prioinherit.c: Limit the number of test
|
|
|
|
|
threads to no more than 3 of each priority. Bad things happen
|
|
|
|
|
when the existing logic tried to created several hundred test
|
|
|
|
|
treads!
|
|
|
|
|
* apps/nshlib/nsh.h: Both CONFIG_LIBC_STRERROR and CONFIG_NSH_STRERROR
|
|
|
|
|
must be defined to use strerror() with NSH.
|
|
|
|
|
* apps/examples/*/*_main.c, system/i2c/i2c_main.c, and others: Added
|
|
|
|
|
configuration variable CONFIG_USER_ENTRYPOINT that may be used to change
|
|
|
|
|
the default entry from user_start to some other symbol. Contributed by

Kate.
|
|
|
|
|
* apps/netutils/webserver/httpd/c: Fix a typo that as introduced in
|
|
|
|
|
version r4402: 'lese' instead of 'else' (Noted by Max Holtzberg).
|
|
|
|
|
* tools/mkfsdata.pl: The uIP web server CGI image making perl script was
|
|
|
|
|
moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl
|
|
|
|
|
(Part of a larger change submitted by Max Holtzberg).
|
|
|
|
|
* apps/netutils/webserver, apps/examples/uip, and apps/include/netutils/httpd.h:
|
|
|
|
|
The "canned" version of the uIP web servers content that was at
|
|
|
|
|
netutils/webserver/httpd_fsdata.c has been replaced with a dynamically
|
|
|
|
|
built configuration located at apps/examples/uip (Contributed by
|
|

|
|
Max Holtzberg).
|
|
|
|
|
* apps/netutils/webserver: Several inenhancements from Kate including the
|
|
|
|
|
ability to elide scripting and SERVER headers and the ability to map
|
|
|
|
|
files into memory before transferring them.
|
|
|
|
|
* apps/netutils/webserver: Add ability to map a URL to CGI function.
|
|
|
|
|
Contributed by Kate.
|
|
|
|
|
* apps/nshlib/nsh_mntcmds.c: The changes of 6.21 introduced holes in the
|
|
|
|
|
error handling: Now the number of arguments to mount can be 0 or 4.
|
|
|
|
|
Additional parameter checking is required to prevent mysterious errors
|
|
|
|
|
(submiteed by Kate).
|
|
|
|
|
* apps/netutils/webserver/httpd_mmap.c: Fix errors when the mmap()
|
|
|
|
|
length is zero (submitted by Kate).
|
|
|
|
|
* apps/netutils/webserver/httpd_sendfile.c: Add and option,
|
|
|
|
|
CONFIG_NETUTILS_HTTPD_SENDFILE to transfer files using the NuttX
|
|
|
|
|
sendfile() interface.
|

* apps/netutils/discover: A UDP network discovery utility contributed
|
|
|
|

by Max Holtzberg.
|
|

|
* apps/examples/discover: A test example for the UDP network discovery
|
|
|
|
|
utility (also contribed by Max Holtzberg).
|
|
|
|
|
* apps/examples/*/main.c: Too many files called main.c. Each renamed
|
|
|
|
|
to something unique so that they will not collide in the archive.
|
|
|
|
|
* apps/netutils/xmlrpc: The Embeddable Lightweight XML-RPC Server

* apps/netutils/uip_listenon.c: Logic in uip_server.c that creates
|
|
|
|
|
the listening socket was moved to this new file to support re-use.
|
|
|
|
|
Contributed by Kate.
|
|
|
|
|
* apps/netutils/webserver/httpd.c: The option CONFIG_NETUTILS_HTTPD_SINGLECONNECT
|
|
|
|
|
can now be used to limit the server to a single thread. Option
|
|
|
|
|
CONFIG_NETUTILS_HTTPD_TIMEOUT can be used to generate HTTP 408 errors.
|
|
|
|
|
Both from Kate.
|

|
|
|
|
|
Kate.
|
|
|
|
|
* apps/netutils/webserver/httpd.c: Add support for Keep-alive connections
|
|
|
|
|
(from Kate).
|
|
|
|
|
* apps/NxWidget/Kconfig: This is a kludge. I created this NxWidgets
|
|
|
|
|
directory that ONLY contains Kconfig. NxWidgets does not live in
|
|
|
|
|
either the nuttx/ or the apps/ source trees. This kludge makes it
|
|
|
|
|
possible to configure NxWidgets/NxWM without too much trouble (with
|
|
|
|
|
the tradeoff being a kind ugly structure and some maintenance issues).
|
|
|
|
|
* apps/examples/Make.defs: Missing support for apps/examples/watchdog.
|
|
|
|
|
* apps/NxWidgets/Kconfig: Add option to turn on the memory monitor
|
|
|
|
|
feature of the NxWidgets/NxWM unit tests.
|
|
|
|
|
* vsn: Moved all NSH commands from vsn/ to system/. Deleted the vsn/
|
|
|
|
|
directory.
|
|
|
|
|
* Makefile: Change order of includes when CONFIG_NEWCONFIG=y. In
|
|
|
|
|
that case, namedapp must be included first so that the namedapp
|
|
|
|
|
context is established first. If the namedapp context is established
|
|
|
|
|
later, it will overwrite any existing namedapp_list.h and nameapp_proto.h
|
|
|
|
|
files.
|
|
|
|
|
* CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences
|
|
|
|
|
of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*.
|
|
|
|
|
* Kconfig: Fleshed out apps/examples/adc/Kconfig and apps/examples/wget/Kconfig.
|
|
|
|
|
There are still a LOT of empty, stub Kconfig files.
|
|
|

|
|
|
|
|
DNS address resolution improvements from Darcy Gong.
|
|
|
|
|
* apps/nshlib/nsh_netcmds.c: The ping command now passes a maximum round
|
|
|
|
|
trip time to uip_icmpping(). This allows pinging of hosts on complex
|
|
|
|
|
networks where the ICMP ECHO round trip time may exceed the ping interval.
|
|
|
|
|
* apps/examples/nxtext/nxtext_main.c: Fix bad conditional compilation
|
|
|
|
|
when CONFIG_NX_KBD is not defined. Submitted by Petteri Aimonen.
|
|
|
|
|
* apps/examples/nximage/nximage_main.c: Add a 5 second delay after the

NX logo is presented so that there is time for the image to be verified.
|
|
|
|
|

|
|
|
* configs/avr-defconfig-4.3.3 - Added --enable-long-long as a GCC
|
|
|
|
|
option.
|
|
|
|
|
* configs/avr-defconfig-4.5.2 - New configuration.
|
|
|
|
|
* Config.in and almost all configurations in configs/ - Changed the
|
|
|
|
|
default nuttx path to $(TOPDIR)/../../nuttx
|
|
|
|
|
* Misc files. Patch provided by Gerd v. Egidy that solves the following
|
|
|
|
|
problems
|
|
|
|
|
- binutils 2.21 is not available on the gnu servers anymore, they replaced
|
|
|
|
|
it with 2.21.1
|
|
|
|
|
- there is some assembler error when compiling gcc for arm, gcc bugzilla
|
|
|
|
|
43999
|
|
|
|
|
- you can't build nuttx for cortex m3/m4 because of a missing instruction
|
|
|
|
|
in the assembler, binutils bugzilla 12296
|
|
|
|
|
* Add support for binutils 2.22 and GCC 4.6.3.
|
|
|
|
|
* Change name of all tools from xxx-elf to xxx-nuttx-elf
|
|
|
|
|
* Added an ARM EABI GCC 4.6.3 configuration (tool name is arm-nuttx-eabi-).
|
|
|
|
|
* ldnxflat: Add support for the R_ARM_REL32 relocation. This relocation
|
|
|
|
|
type was not generated by GCC/LD prior to gcc-4.6.3
|
|
|
|
|
* R_ARM_REL32 logic is conditionally disabled because it has not been
|
|
|
|
|
tested.
|
|
|
|
|
* ldnxflat: Correct a memory allocation error that could cause written
|
|
|
|
|
past the end of allocated memory. Partial restoration of R_ARM_REL32
|
|
|
|
|
logic. There are lots of issues that I still do not understand here.

pascal-3.0 2011-05-15 Gregory Nutt <gnutt@nuttx.org>
|
|
|
|
|
|
|
|
|
|
* nuttx/: The Pascal add-on module now installs and builds under the
|
|
|
|
|
apps/interpreters directory. This means that the pascal-2.1 module is
|
|
|
|
|
incompatible with will all releases of NuttX prior to nuttx-6.0 where the
|
|
|
|
|
apps/ module was introduced.

|
|
|
|
* Add patch submitted by Dimiter Georgiev to work around problems in building
|
|
|
|
|
GDB 6.8 with versions of Cygwin > 1.7.
|
|
|
|
|
* configs/i486-defconfig-4.3.3 - Builds an i486 cross development toolchain
|
|
|
|
|
using gcc 4.3.3. Why wouldyou want such a thing? On Linux, of course,
|
|
|
|
|
such a thing is not needed because you can use the installed GCC to build
|
|
|
|
|
i486 ELF binaries. But that will not work under Cygwin! The Cygwin
|
|
|
|
|
toolchain (and probably MinGW), build DOS MZ format executables (i.e.,
|
|
|
|
|
.exe files). That is probably not usable for most NuttX targets.
|
|
|
|
|
Instead, you should use this i486-nuttx-elf-gcc to generate true ELF binaries
|
|
|
|
|
under Cygwin.
|
|
|
|
|
* Makefile - Alter copy arguments to avoid permissions problems when
|
|
|
|
|
copying NuttX header files.
|
|
|
|
|
* toolchain/nxflat/nxflat.mk and Makefile - Fix include paths.
|
|
|
|
|
* toolchain/gcc/3.3.6 - Added a patch to fixed compilation error on Ubuntu
|
|
|
|
|
9.10.
|
|
|
|
|
* toolchain/nxflat/Makefile - Correct static library link order.
|
|
|
|
|
* configs/arm920t-defconfig-4.3.3 - Enable support for NXFLAT tools.
|
|
|
|
|
* toolchain/binutils/2.21 and toolchain/gcc/4.5.2 - Add support for GCC
|
|
|
|
|
4.5.2 with binutils 2.21.
|
|
|
|
|
* configs/arm920t-eabi-defconfig-4.5.2 - Add a configuration to build a
|
|
|
|
|
GCC 4.5.2 EABI ARM toolchain for the ARM920t.
