This adapter allows you to use an Olimex 20-pin ARM JTAG programmer to program/debug an ARM microcontroller system that uses a 20-pin SWD interface.
For example, this will allow you to perform in-circuit programming/debugging on the LPC-P1343 board, when connected to an ARM-USB-OCD-H or ARM-USB-TINY-H.
Note that this adapter is not supported in OpenOCD yet. It only is supported in Rowley CrossWorks.
The adapter measures 50 × 40 mm (2.0 × 1.6"). It attaches directly to your programmer; the JTAG cable then goes from the adapter to the target.

Note that this does not adapt to the 20-pin 0.05"-pitch Cortex Debug+ETM Connector; it only adapts to the 0.1"-pitch SWD connector as seen on the LPC-P1343.
