Having never used JTAG before I thought I’d see what I could do with my new Bus Pirate and one of the old ADSL routers I have lying around – ideally reading/writing to the flash. The v1 BT Home Hub is a Broadcom BCM6348-based device with 32MB RAM, that I’d previously added headers for the serial uart and replaced the bootloader with RedBoot and the OS with openwrt. You can see a small breakout with a TTL level converter and an FTDI uart<->USB on the right, and the Bus Pirate on the left in the picture above.

Get your own handy Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
