Extracting Firmware from External Memory via JTAG

Demonstration of extracting firmware from an embedded system through the JTAG interface.

The target board is a MIPS-based Linksys WRT54G v2 router containing an Intel 28F320 4MB external Flash memory. Tools used are the Bus Blaster JTAG hardware interface (http://dangerousprototypes.com/docs/Bus_Blaster) and UrJTAG open source software (http://urjtag.org).
