the Olimex SAM7-EX256 board.
AVR-AT90CANx-GCC - Port on AVR AT90CAN128, not complete yet.
*****************************************************************************
*** Plans ***
*****************************************************************************
- Restart the work on the AVR port ASAP.
- Look into importing or implementing a TCP/IP stack and a File System.
- Start the work on a Cortex-M3 port as soon GCC 4.3.0 will be released.
- Evaluate other architectures for a possible ChibiOS/RT port.
*****************************************************************************
*** Releases ***
*****************************************************************************
*** 0.5.5 ***
- Reorganized the code of the two ARM7 ports, now all the common ARM7 code
is in ./ports/ARM7. This will make maintenance and new ARM7 ports much
easier.
*** 0.5.4 ***
- Port for Atmel AT91SAM7X256 introduced, the port should be useable also on
SAM7S and SAM7XC but no tests were performed. Other SAM7 processors should
