<b>STMicro STM3240G-EVAL</b>.
|
||||
This port uses the Freescale STMicro STM3240G-EVAL board featuring the STM32F407IGH6 MCU.
|
||||
Refer to the <a href="http://www.st.com/internet/evalboard/product/252216.jsp">STMicro web site</a> for further information about this board.
|
||||
</p>
|
||||
<p>
|
||||
<b>STATUS:</b>
|
||||
As of this writing, the basic port is complete and passes the NuttX OS test.
|
||||
An additional, validated configuration exists for the NuttShell (NSH, see the
|
||||
<a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
|
||||
This basic port first appeared in NuttX-6.12.
|
||||
A more complete port with support for SDIO, Ethernet, and USB OTG is expected in future releases.

nuttx-6.12 2011-12-06 Gregory Nutt <gnutt@nuttx.org>
|
||||
|
||||
* arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not
|
||||
selected. Doing so will cause errors if other configuration dependencies
|
||||
are not met.
|
||||
* configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD
|
||||
do not work with R61580 LCD.
|
||||
* configs/pic32-starterkit: Beginning of a configuration for the Microchip
|
||||
PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this
|
||||
with no serial port?!
|
||||
* lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it
|
||||
closes a read-only file. This is because it calls flush() which will
|
||||
fail on read-only files. No harm is done other that a bad value is
|
||||
returned.
|
||||
* arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old
|
||||
libboard.a was not being cleaned.
|
||||
* arch/mips/src/pic32mx/pic32mx-gpio*.c: Add GPIO support for the PIC32MX.
|
||||
* configs/sure-pic32mx/src/up_leds.c and up_buttons.c: Add button and LED
|
||||
support for the Sure Electronics PIC32MX board.
|
||||
* configs/ea3152: Add a configuration for the Embedded Artists LPC3152
|
||||
daughter board (with the same base-board used with configs/ea3131)
|
||||
* graphics/nxmu/nx_getrectangle.c, graphics/nxsu/nx_getrectangle.c,
|
||||
graphics/mxtk/nx_getwindow.c, graphics/nxmu/nx_gettoobar.c: New
|
||||
interfaces to read from graphics memory
|
||||
* graphics/nxbe/nxbe_bitmap.c: Fix an error in the error handling that
|
||||
can cause valid bitmaps to fail to render.
|
||||
* include/nuttx/rgbcolors.h: Fix errors in some 16- and 8-bit color
|
||||
conversion macros.
|
||||
* tools/incdir.sh: Fix issues when g++ is used as the compiler. It was
|
||||
not being recognized and handled properly.
|
||||
* graphics/nxsu/nx_releasebkgd.c: Fix a bad cast that was causing
|
||||
problems with the background window was released.
|
||||
* fs/nxffs/nxffs_pack.c: Correct a critical bug in the NXFFS file system:
|
||||
When repacking the filesystem, there was a missing check to see if an
|
||||
inode structure would fit at the end of a block. This is a rare case
|
||||
if the block size is large, but can be common for tiny block sizes
|
||||
and results in a crash and file system corruption.
|
||||
* fs/nxffs/nxffs_initialize.c: Fix an initialize error. If the FLASH
|
||||
is full on power-up, NXFFS will fail to initialize correctly.
|
||||
* fs/nxffs/nxffs_write.c and nxffs_pack.c: Fix an error that can occur
|
||||
when attempt to write to FLASH volume that is completely full but
|
||||
has no value inodes on it.
|
||||
* drivers/mtd/at24xx.c: Now supports a configurable block size that
|
||||
supports using "clusters" of AT24 pages as blocks. This allows bigger
|
||||
block sizes and more efficient use of EEPROM when the AT24 is used to
|
||||
support a file system (such as NXFFS). (Contributed by Hal Glenn).
|
||||
* include/nuttx/rgbcolors.h: More fixes to RGB color conversion
|
||||
macros.
|
||||
* arch/arm/src/common/up_createstack.c and up_usestack.c: For ARM EABI
|
||||
the stack must be aligned to 8-byte boundaries. This is necessary for
|
||||
passing aligned floating point values under EABI. Fix contributed by
|
||||
David Sidrane.
|
||||
* Numerous changes and fixes to the PIC32 interrupt handing logic. The
|
||||
PIC32 port is almost complete but still not ready for prime time.
|
||||
* fs/fat/fs_fat32util.c and fs_fat32.h: Logic extended to look in up to
|
||||
four partitions for a valid FAT file system.
|
||||
* drivers/input/tsc2007.c: Add support for 8-bit conversions; make sure
|
||||
that A/D converters are active before requesting conversions.
|
||||
* drivers/mmcsd0/mmcsd_sdio.c: Increase capacity variable from size_t
|
||||
to uin64_t (if available) so that SD cards with capacities greater
|
||||
than 4Gb can be supported.
|
||||
* fs/fat/fs_fat32dirent.c: The root directory structure is different
|
||||
from other directories. When formatted by Windows, it is not initialized
|
||||
at all. Some additional special handling is required to initialize the
|
||||
root directory entry to interoperate correctly with windows.
|
||||
* fs/fat/fs_fat32util.c: In fat_systime2fattime(void) should be
|
||||
clock_gettime() and not clock_gettime(). Also, there is a place where
|
||||
FAT date is used instead of FAT time. (Thanks to David Sidrane).
|
||||
* arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the
|
||||
STM32F40xxx family of MCUs.
|
||||
* configs/stm3240g-eval: Add framework for the STMicro STM3240G-EVAL
|
||||
board.
|
||||
* include/sys/types.h: wchar_t is a builtin type in C++ and its
|
||||
declaration can cause errors with certain C++ compilers.
|
||||
* sched/sig_timedwait.c: Fix signal handling when the returned info
|
||||
is NULL. Before this change, it would derefence a NULL pointer
|
||||
in this case.
|
||||
* graphics/nxfonts/nxfonts_sans17x22.h and nxfonts_sans20x26.h: Add
|
||||
some very small sans serif fonts.
|
||||
* graphics/nxfonts/nxfonts_sans17x23b.h and nxfonts_sans20x27b.h: Add
|
||||
corresponding sans serif bold fonts.
|
||||
* drivers/input/ads7843e.c and tsc2007.c: Fix some errors in the poll
|
||||
setup error checking that was cloned into both drivers.
|
||||
* sched/mq_notify.c: Set errno appropriately on failures. There are
|
||||
still several message queue functions that do not set errno!
|
||||
* arch/arm/src/stm32: Fixes to several STM32F40xxx files (contributed by
|
||||
Mikhail Bychek).
|
||||
* configs/stm3210e-eval/src/up_lcd.c: Fix banding problem on the R61580
|
||||
LCD
|
||||
* configs/stm3240g-eval/ostest: The basic STM32F40xx bringup is functional
|
||||
(11/12/06) for the STM3240G-EVAL board and passes the OS test.
|
||||
* configs/stm3240g-eval/nsh: Adds a NuttShell (NSH) configure for the
|
||||
STM3240G-EVAL board.

||||
