 ** TARGET **
 
-The demo runs on an ST STM32VL-Discovery board.
+The demo runs on an ST STM32L-Discovery board.
 
 ** The Demo **
 
 The demo shows how to use the ADC, PWM and SPI drivers using asynchronous
 APIs. The ADC samples two channels (temperature sensor and PC0) and modulates
 the PWM using the sampled values. The sample data is also transmitted using
-the SPI port 1.
+the SPI port 2 (NSS=PB12, SCK=PB13, MISO=PB14, MOSI=PB15).
 By pressing the button located on the board the test procedure is activated
 with output on the serial port COM1 (USART1).

+*****************************************************************************
+** ChibiOS/RT port for ARM-Cortex-M3 STM32F100xB.                          **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an ST STM32F4-Discovery board.
+
+** The Demo **
+
+The demo shows how to use the ADC, PWM and SPI drivers using asynchronous
+APIs. The ADC samples two channels (temperature sensor and PC1) and modulates
+the PWM using the sampled values. The sample data is also transmitted using
+the SPI port 2 (NSS=PB12, SCK=PB13, MISO=PB14, MOSI=PB15).
+By pressing the button located on the board the test procedure is activated
+with output on the serial port SD2 (USART2).
+
+** 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 distribited
+with ChibiOS/RT, you can find the whole library on the ST web site:
