This release focuses on a few new features.
|
||||
<ul>
|
||||
<li>
|
||||
The basic port for the FreeScale ARM920T i.MX1 processor on the
|
||||
Freescale MX1ADS board. Coding is complete for this port, but it is
|
||||
has not yet fully integrated.
|
||||
</li>
|
||||
<li>
|
||||
Extended I2C and SPI interface definitions
|
||||
</li>
|
||||
<li>
|
||||
Add basic support for C++ applications. Very simple C++ applications
|
||||
can now be built against NuttX without any external libraries. At
|
||||
present, only the most primitive C++ programs are supported, but it
|
||||
is hoped that this support will be extended in future releases.
|
||||
</li>
|
||||
</ul>
|
||||
The release features support for the Micromint 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.
|
||||
</p>
|
||||
<p>
|
||||
See the Changelog for a detailed description of these changes.
|
||||
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).

|
||||
|
||||
* Add an enumeration argument to the SPI chip select and status methods so
|
||||
that the interface can handle more than one device.
|
||||
* eZ80Acclaim!: Add a generic SPI driver for all eZ80 boards.
|
||||
* Add a setmode() method to the SPI interface to handle parts with differing
|
||||
mode requirements.
|
||||
* include/nuttx/i2c.h: Defined a standard I2C interface
|
||||
* eZ80Acclaim!: Add an I2C driver.
|
||||
* eZ8Encore!: Add an I2C driver.
|
||||
* Add support for the Freescale i.MX1/L architecture and a configuration for
|
||||
the Freescale MX1ADS development board.
|
||||
* examples/helloxx: Added a simple C++ hello world example
|
||||
* include/css: Added std header files
|
||||
* libxx: New C++-only directory provides support for minimal C++ applications
|
||||
* 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.
|

1. Make sure you exit minicom (or whatever terminal emulator you are

using). It will interfere with the download.

2. On the MCU123 board, I need to put a jumper on JP3-INT. On that board,
|

JP3-INT is connected to P0.14 of LPC214x. When P0.14 is low and RTS is

changed from high to low, the LPC214x will enter ISP (In System Programming)
