Hi murpf,

You can check this post which is related to the Bus Pirate using JTAG.

The author left out vcc connection for he's using the target's power as stand alone, but I can't find where he connects the Reset :(

Cheers,

EDIT: I did some more research and found that the TRST pin should be connected to PGD (the pin on the programming header).
