*****************************************************************************
** ChibiOS/RT port for ARM7TDMI AT91SAM7X256. **
*****************************************************************************
** TARGET **
The demo runs on an Olimex SAM7-EX256 board.
** The Demo **
Work in progress, not finished yet.
** Build Procedure **
The demo was built using the YAGARTO toolchain but any toolchain based on GCC
and GNU userspace programs will work.
** Notes **
Some files used by the demo are not part of ChibiOS/RT but are Atmel copyright
and are licensed under a different license, see the header present in all the
source files under ./demos/AT91SAM7X256/at91lib for details.
Also note that not all the files present in the Atmel library are distribuited
with ChibiOS/RT, you can find the whole library on the Atmel web site:
http://www.atmel.com
