Lpc2000

Hi

I use the J-Link and sometimes there are quite a lot of problems 
with it and sometimes it works quite well.

What I have found is that it is deadly to have programmed an 
operating code via ISP. I can't explain why but the debugger hangs 
and crashes and often doesn't want to do anything sensible.

When I delete the code form FLASH (using ISP again - ie. Philips 
upload uitility) all is very stable again.

Could this help?

Regards
