*****************************************************************************
** ChibiOS/RT port for ARM-Cortex-M4 STM32F407. **
*****************************************************************************
** TARGET **
The demo runs on an ST STM32F4-Discovery board.
** The Demo **
** Build Procedure **
The demo has been tested by using the free Codesourcery GCC-based toolchain
and YAGARTO. just modify the TRGT line in the makefile in order to use
different GCC toolchains.
** Notes **
Some files used by the demo are not part of ChibiOS/RT but are copyright of
ST Microelectronics and are licensed under a different license.
Also note that not all the files present in the ST library are distributed
with ChibiOS/RT, you can find the whole library on the ST web site:
