The release features support for the <a href=" http://www.micromint.com/">Micromint</a>
|
||||
Eagle-100 development board.
|
||||
This board is based around, the Luminary LM3S6918 MCU.
|
||||
This is the first ARM Cortex-M3 architecture supported by Nuttx.
|
||||
This initial, basic port includes timer and serial console with configurations to execute the NuttX OS test and to run the <a href="NuttShell.html">NuttShell (NSH)</a>.
|
||||
Work is still underway on this port and current plans are to have I2C, SSI, MMC/SD, and and Ethernet driver in the 0.4.7 release.
|
||||
This release focuses on cleaning up and extending the Eagle100/LM3S6918 port released
|
||||
in nuttx-0.4.6 and on improved MMC/SD support. New features include:
|
||||
<ul>
|
||||
<li>
|
||||
Improved reliably and additional drivers for the Eagle-100 board (LM3S6918
|
||||
ARM Cortex-M3). Additional drivers include Ethernet, SSI, and support for
|
||||
the on-board LEDs and microSD cards.
|
||||
</li>
|
||||
<li>
|
||||
The SPI-based MMC/SD driver was extended to support SDHC Version 2.xx cards.
|
||||
</li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
Additional work was done on the MXADS i.MX1 port, however, that work has been set aside
|
||||
until I complete work on the Eagle-100 (I also need to come up with a 3V power supply).
|
||||
</p>
|
||||
<p>
|
||||
Other changes in this release include: Extensions to the SPI interface definition in order to handle 9-bit interfaces to displays.
|
||||
Several bugs were fixed (see the <a href="#currentrelease">ChangeLog</a> for a complete list of changes).
|
||||
In addition, this release includes several important bugfixes for the LM3S6918, the LPC2148,
|
||||
the SPI-based MMC/SD driver, and to FAT32. See the ChangeLog for details of these bugfixes.

|

|
||||
* Change SPI interface so that is can accomodate interfaces where the
|
||||
number of bits per word is greater an 8 (such as with many 9-bit display
|
||||
interfaces). -- this might have broken a few things which will need to
|
||||
be retested!
|
||||
* arch/arm/src/imx: Added i.MX SPI driver
|
||||
* SPI: Add a method to set the number of bits per word. Also add an
|
||||
alternative interface for so that (eventually) I can phase the sndblock
|
||||
and recvblock methods and replace them with a single exchange method
|
||||
* Build: objcopy fails with toolchains that use newer GCC and binutils. The
|
||||
following arguments need to be included in the objcopy command line "-R .note
|
||||
-R .note.gnu.build-id -R .comment" This has bin fixed in arch/arm/src/Makefile,
|
||||
but other architectures may have the same problem. Thanks to Dave Marples
|
||||
for verifying this.
|
||||
* configs/eagle100/ostest: Added support for the MicroMint Eagle100 board.
|
||||
This board has a Luminary LM3S6918 Cortex-M3. Added a configuration to build
|
||||
examples/ostest.
|
||||
* arch/arm/src/lpc214x: Add configuration option to enable fast GPIO (vs.
|
||||
legacy, "slow" GPIO) for LPC214x.
|
||||
* arch/arm: Restructured the arch/arm directory structure to better suppor ARM
|
||||
and Cortex-M3.
|
||||
* sched/: pthread_create() must return a (non-negated) errno value on failure.
|
||||
* configs/eagle100/nsh: Add a NuttShell (NSH) configuration for the Eagle-100
|
||||
* arch/arm/src/lm3s: Added an Ethernet driver for the LM3S6918
|
||||
* configs/eagle100/nettest: Added an examples/nettest configuration for the
|
||||
Micromint Eagle100 board.
|
||||
* Documentation/NuttxPortingGuide.html: Added a section on NuttX device drivers.
|
||||
* configs/eagle100/httpd: Added an examples/uip configuration for the
|
||||
Micromint Eagle100 board.
|
||||
* arch/arm/src/lm3s: Added an SSI driver for the LM3S6918
|
||||
* examples/nsh: Added MMC/SD support for the LM3S6918
|
||||
* arch/arm/src/lm3s: Fix logic for setting and clearing output GPIOs (critical
|
||||
fix!).
|
||||
* drivers/mmcsd: Found numerous errors in current MMC/SD SPI driver. Bad frequency
|
||||
calculation based on CSD settings, inappropriate timeouts, odd code that looks like
|
||||
a bad search and replace. Also needs support for SDHC ver 2.x. New MMC/SD is
|
||||
largely redesigned and probably non-functional in the first check-in.
|
||||
* drivers/mmcsd: Changes verified on 4Gb Kingston microSHDC card and on a 2Gb
|
||||
SanDisk microSDC card on the Eagle100 platform.
|
||||
* fs/fat: With the 4Gb card, the first tests of FAT32 were (finally) performed.
|
||||
Found and corrected a problem that prevented use of FAT32: It was not updating
|
||||
the sector cache before checking the FAT32 FSINFO sector.
|
||||
* configs/eagle100/*/Make.defs: Added configuration options that should make
|
||||
it possible to build NuttX for the Eagle100 using CodeSourcery 2009q1 toolchain
|
||||
and the devkitARM GNU toolchain.
|
||||
* configs/mcu123-lpc214x/src: Corrected some logic in the LPC2148 SPI receive block
|
||||
logic. Re-verified SDC ver1.x support with 1Gb Toshiba SDC, 1Gb PNY SDC, and
|
||||
4Gb Kingston SDHC. There are CMD0 issues with the 2Gb SanDisk SDC on this board.
|
||||
* fs/fs_mount.c: Corrected error handling that could cause a deadlock on certain
|
||||
mount() failures.
