This is a page about using JTAG with Maple - JTAG will allow you to use a debugger like GDB to debug programs running on the Maple. You can also use the JTAG adapter to re-flash (re-install) the bootloader in case you "brick" the board and can't install programs on it via the bootloader.

JTAG Debugger

You need a JTAG debugger to manage the connection and debugging of the Maple. These plug into your computer via USB and into the Maple via its JTAG port.

JTAG Adapter

Maple's 8-pin JTAG port is non-standard, so you need an adapter circuit to go between the ARM 20-pin connector and the Maple 8-pin connector.
