NuttX-6.24
|
||||
^^^^^^^^^^
|
||||
|
||||
The 91st release of NuttX, Version 6.24, was made on December 20, 2012,
|
||||
and is available for download from the SourceForge website. Note
|
||||
that release consists of two tarballs: nuttx-6.24.tar.gz and
|
||||
apps-6.24.tar.gz. Both may be needed (see the top-level nuttx/README.txt
|
||||
file for build information).
|
||||
|
||||
This release corresponds with SVN release number: r5447

||||

Note that all SVN information has been stripped from the tarballs. If you
|

|
||||

|
||||
|
||||
Additional new features and extended functionality:
|
||||
|
||||
* RTOS:
|
||||
|
||||
- Implemented the POSIX pause() function (still has some compiance
|
||||
issues).
|
||||
- Tasking logic is extended to support the notion of address
|
||||
environments. An address environment is the key notion underlying
|
||||
"process" vs. tasks. If tasks are created with address environments
|
||||
(by binfmt), the OS will propogate that environment to child threads
|
||||
and will destroy the address environment when the "process" exists.
|
||||
- If support for the PATH variable is enabled, the OS start up logic
|
||||
will create an initial environment containing the default PATH
|
||||
setting (CONFIG_PATH_INITIAL). This initial PATH will then be
|
||||
inherited by all tasks.
|
||||
|
||||
* Binfmt
|
||||
|
||||
- The NuttX binary loaders have been updated to support the PATH
|
||||
environment variable. Now, if the PATH is properly defined, programs
|
||||
can be executed from mass storage using only the file name. This
|
||||
feature is added to support more standard behavior (eventually, NSH
|
||||
will support execution of programs in file systems by just entering
|
||||
the file name, perhaps in 6.25?).
|
||||
- The NXFLAT and ELF binary loaders have been extended to create
|
||||
address environments for any new tasks executed from the file system.
|
||||
This feature requires that the architecture support a memory management
|
||||
unit (MMU) and the address environment interfaces declared in
|
||||
include/nuttx/arch.h (currently, this is only supported by the z180).
|
||||
|
||||
* Drivers: LCD driver for the Univision UG-2864AMBAG01 OLED
|
||||
|
||||
* STM32: Support for STM32F100 high density chips contributed by Freddie
|
||||
Chopin.
|
||||
|
||||
* STM32 Drivers: Added optional RS-485 direction bit control (from
|
||||
Freddie Chopin).
|
||||
|
||||
* STM32 Boards:
|
||||
|
||||
- Support for generic STM32F100RC board contributed by Freddie Chopin.
|
||||
- stm32f4discovery/nxlines: STM32F4Discovery support for the
|
||||
UG-2864AMBAG01 OLED.
|
||||
- stm32f4discovery/winbuild: A version of the NuttX OS test
|
||||
configured to build natively on Windows.
|
||||
- stm32f4discovery/elf: Now uses the PATH variable to find ELF
|
||||
executables.
|
||||
- configs/cloudctrl: Added for Darcy Gong's CloudController board
|
||||
|
||||
* PIC32 Boards: Update the Mirtool configuration for Release 2 of the
|
||||
Mirtoo module.
|
||||
|
||||
* Calypso: Add Calypso keypad driver. From Denis Cariki.
|
||||
|
||||
* ZiLOG:
|
||||
|
||||
- Add support for the z180 chip family and, specifically, for
|
||||
the P112 retro hardware (see http://p112.feedle.net/).
|
||||
- All ZiLOG configurations updated to use the current ZDS-II
|
||||
and/or SDCC toolchains.
|
||||
|
||||
* Graphics:
|
||||
|
||||
- Add a semaphore handshake so that operations on buffers from
|
||||
the NXMU client will be blocked until the NX server operates on the
|
||||
buffer data (from Petteri Aimonen).
|
||||
- nxtk_subwindowmove() and nxtk_getwindow(): Improvements to clipping
|
||||
logic from Petteri Aimonen.
|
||||
|
||||
* C Library: lib/ sub-directory renamed libc/ (there is a new lib/ sub-
|
||||
directory that is used to hold all archives).
|
||||
|
||||
* C++: Exception stubs from Petteri Aimonen.
|
||||
|
||||
* Applications:
|
||||
|
||||
- Add NSH hexdump command to dump the contents of a file (or character
|
||||
device) to the console (contributed by Petteri Aimonen).
|
||||
- Extend the NSH ifconfig command plus various DHCPC improvements
|
||||
(from Darcy Gong).
|
||||
|
||||
* apps/examples:
|
||||
|
||||
- ostest: Replace large tables with algorithmic prime number
|
||||
generation. This allows the roundrobin test to run on platforms
|
||||
with minimal SRAM (Freddie Chopin).
|
||||
- keypadtest: A new keypad test example contributed by Denis Carikli.
|
||||
- elf and nxflat: If CONFIG_BINFMT_EXEPATH is defined, these examples
|
||||
will now use a relative path to the program and expect the binfmt/
|
||||
logic to find the absolute path to the program using the PATH
|
||||
variable.
|
||||
|
||||
* Build system:
|
||||
|
||||
- New top-level Makefiles: Makefile.unix and Makefile.win (along with
|
||||
numerous changes to other make-related files). This adds basic
|
||||
support for building NuttX natively under Windows from a CMD.exe
|
||||
window (rather than in a POSIX-like environment). This build: (1)
|
||||
Uses all Windows style paths, (2) Uses primarily Windows batch
|
||||
commands from cmd.exe, with (3) a few extensions from GNUWin32.
|
||||
|
||||
This capability should still be considered a work in progress
|
||||
because: (1) it has not been verfied on all targets and tools,
|
||||
and (2) still lacks some of the creature-comforts of the more
|
||||
mature environments (like a function configure.sh script and
|
||||
'make menuconfig' support).
|
||||
|
||||
- Example Windows native builds for STM32F4Discovery, eZ80, z16f, z8,
|
||||
Z80, and Z180.
|
||||
- Several configurations have been converted to work the kconfig-
|
||||
frontends mconf configuration tool: stm32f4discovery/nxlines, and
|
||||
all eZ80, z16f, z8, Z80, and Z180 configurations.
|
||||
- Architectures now include a common Toolchain.defs file that can be
|
||||
used to manage toolchains in a more configurable way (most of this
|
||||
contributed by Mike Smith).
|
||||
|
||||
* Build tools:
|
||||
|
||||
- Renamed tools/winlink.sh to tools/copydir.sh.
|
||||
- Several new tools/scripts to support the Windows native build:
|
||||
tools/mkdeps.bat, tools/mkdeps.c, tools/link.bat, unlink.bat, and
|
||||
copydir.bat.
|
||||
- tools/incdir.sh and incdir.bat now support an -s option to generate
|
||||
system header file paths.
|
||||
- tools/b16.c: Fixed precision math conversion utility.
|
||||
|
||||
Bugfixes (see the change log for details). Some of these are very important
|
||||
(marked *critical*):
|
||||
|
||||
* RTOS: Fix some backward conditional compilation in the work queue
|
||||
logic (Freddie Chopin).
|
||||
|
||||
* File System: Uninitialized variable caused assertions (from Lorenz
|
||||
Meier).
|
||||
|
||||
* Drivers: Partial fix for STM32 OTGFS device drivers and fix for short,
|
||||
unaligned writes in the flash translation layer (drivers/mtd/ftl.c),
|
||||
both from Petteri Aimonen.
|
||||
|
||||
* STM32 Drivers:
|
||||
|
||||
- Qencoder driver and TIM3 driver fixes from Ryan Sundberg.
|
||||
- Fix timeout delay calculation in the STM32 OTG FS host driver.
|
||||
|
||||
* LPC17xx Drivers: Resources not being properly released when I2C
|
||||
driver is un-initialized.
|
||||
|
||||
* Graphics:
|
||||
|
||||
- Fix logic when the mouse drags outside of the window; fix
|
||||
another "blocked message" handling case (both from Petteri Aimonen).
|
||||
- nxtk_filltrapwindow(): Correct an offset problem (also from Peterri
|
||||
Aimonen).
|
||||
- nxglib_splitline(): Correct the "fat flat line" bug.
|
||||
|
||||
* C Library:
|
||||
|
||||
- nrand() changes to prevent coefficients from becoming zero which
|
||||
would "lock up" the random number generate.
|
||||
- Add rounding functions to the math library (contributed by Petteri
|
||||
Aimonen).
|
||||
|
||||
* Build system: Changes to MIN definitions in all limit.h header files
|
||||
to avoid integer overflows. For example from (-128) to (-127 - 1)
|
||||
(from Petteri Aimonen).
|
||||
|
||||
* Applications: Modbus fixes from Freddie Chopin.
|
||||
|
||||
As well as other, less critical bugs (see the ChangeLog for details)
