+** ChibiOS/RT + FatFS demo for SAM7. **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Olimex SAM-EX256 board. The port on other boards or other
+members of the SAM7 family should be an easy task.
+
+** The Demo **
+
+This demo shows how to integrate the FatFs file system and use the SPI and MMC
+drivers.
+The demo flashes the board LCD background using a thread and monitors the MMC
+slot for a card insertion. When a card is inserted then the file system is
+mounted and the LCD background flashes faster.
+A command line shell is spawned on SD1, all the interaction with the demo is
+performed using the command shell, type "help" for a list of the available
+commands.
+
+** Build Procedure **
+
+The demo was built using the YAGARTO toolchain but any toolchain based on GCC
+and GNU userspace programs will work.
