I was wrong about my original interface, I'd got the DB25 connected up
incorrectly - I'd designed the PCB for a female instead of a male
connector. Cutting a few tracks and rewiring my home-made prototype
PCB correctly got it working.

It seems to work OK without a connection to nTRST. nTRST on the target
board should be tied high through a 10k resistor and connected to pin
3 of the JTAG connector if you want compatibility with the Wiggler.

I'll upload the corrected files in a day or so when I've made a new
PCB and checked that it works.
