Hi!

Another nice solution is the Tag Connect...
http://www.tag-connect.com/
Needs only the landing pads an some holes on the PCB.

Ciao

ok, so make this the "show your programming probe" week:

http://vp7.de/swd_probe.jpg

this one is only for field upgrades, normally I have a pogo jig since I also
test other parts of the partly populated PCB.
