2+** ChibiOS/RT port for ARM-Cortex-M3 STM32F107. **
3+*****************************************************************************
4+
5+** TARGET **
6+
7+The demo runs on an Olimex STM32-P107 board.
8+
9+** The Demo **
10+
11+The demo flashes the board LED using a thread, by pressing the button located
12+on the board the test procedure is activated with output on the serial port
13+SD3 (USART3).
14+The demo also starts the ethernet driver using the IP address configured in
15+lwipthread.h.
16+
17+** Build Procedure **
18+
19+The demo has been tested by using the free Codesourcery GCC-based toolchain.
20+Just modify the TRGT line in the makefile in order to use different GCC ports.
21+The demo requires the lwip 1.4.0.rc1 stack, which is included in ./ext and
22+should be extracted to ./ext/lwip
23+Additionally, the demo requires the ST firmware library, which is included in
24+./ext
25+
26+** Notes **
27+
28+Some files used by the demo are not part of ChibiOS/RT but are copyright of
29+ST Microelectronics and are licensed under a different license.
30+Also note that not all the files present in the ST library are distribited
31+with ChibiOS/RT, you can find the whole library on the ST web site:
32+
33+ http://www.st.com
34+
35+The lwIP stack also has its own license, please read the info into the included
36+lwIP distribution files.
