+*****************************************************************************

+** ChibiOS/RT port for ARM-Cortex-M4 STM32F407.                            **

+*****************************************************************************

+

+** TARGET **

+

+The demo runs on an Olimex STM32-P407 board.

+

+** The Demo **

+

+The demo currently just flashes a LED using a thread and serves HTTP requests

+at address 192.168.1.20 on port 80.

+The button activates che ChibiOS/RT test suite, output on SD6.

+

+** 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 ports.

+

+** 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 distribited

+with ChibiOS/RT, you can find the whole library on the ST web site:
