nuttx-0.4.6
^^^^^^^^^^^
This is the 38th release of NuttX. 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 NuttShell (NSH). 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.
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).
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
ChangeLog for a complete list of changes).

Here are the detailed steps I use:
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
