Bus Blaster and OpenOCDWarning: OpenOCD does not fully support the CortexM4 yet and this method

may damage your hardware. I am not an expert OpenOCD user. Use at your own risk.

The Bus Blaster is an open hardware JTAG debugger made by Dangerous Prototypes, which you can get for about $35 atSeeedStudio. Any debugger compatible with Open On-Chip Debugger (OpenOCD) should work fine for these instructions.
