Introduction
The STM32F3DISCOVERY is a small circuit board with a great microcontroller. The ARM Cortex-M4 chip has 256 KB of flash memory, 48 KB of RAM, USB and more. The board has huge amounts of header pins connected to the microcontroller and has a gyroscope, accelerometer and compass on board. For the 11 USD that this board costs, you definitely get a lot of functionality.
The board also has 2 USB ports, one which is connected directly to the microcontroller, and the other connected to the smaller microcontroller pictured above (STM32F1) and is used for programming and debugging the device. STMicroelectronics calls the programming solution ST-Link/V2. When used with the proper software, it works quite well. However Linux support was initially lacking, but texane and OpenOCD were able to create working drivers. My goal was to dump the firmware.
