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) |
