Debricking using the Bifferboard
Bifferboard GPIO pin signal levels appear to be compatible with the photo frame, and, indeed, no external resistors are required to connect the two devices. Assuming the JTAG port has been modded for GPIO, simply connect the two together, but don't connect the +3.3v lines!
You can build openocd as follows:
$ git clone git://openocd.git.sourceforge.net/gitroot/openocd/openocd openocd
$ cd openocd
* Now copy parport.c to the src/jtag/drivers directory to overwrite the original parport.c file *
$ ./configure --enable-parport --enable-parport_ppdev
