1. Your wire is a little too long and consider lower the clock if the result is not consistent.
2. You need to use u-link Diagram not USB BDM NT diagram.
DSI Brown.
DSO Orange.
CLK Green.
BEER Purple
FREEZE Gray
RESET Blue.
3. Your u-link NT needs to activated to get it working properly.

I can help you remotely via zoom remote desktop.
i have changed the wire length , i'll use the u link diagram/ thanks for the list i'll report back findings, and you have already sent me my activation code and i have put it in the software already 8)
& thanks for the offer for zoom , if i really really get stuck i'll take you up on the offer. , for now i think its just me over thinking the connections :lol:
