Is the nTRST the only problem?
If it is, than I think it would be easier for me to fix the hardware because I don’t have the right SW tools to build the OpenOCD and it is probabl easier to fix for me.
You should probably add this “wiggler_ntrst_inverted” to the next version of OpenOCD or change the schematics for that wiggler.
So, what is the correct reset_config:
“reset_config trst_and_srst srst_pulls_trst”
or
“reset_config trst_and_srst”
with my wiggler (when I fix the nTRST)?
Looking at the scope pictures you took nTRST seems to be the only problem, so changing this signal to non-inverted should work.
The correct reset_config for for a LPC2xxx is “reset_config trst_and_srst srst_pulls_trst”, as the LPC internally asserts nTRST whenever nSRST is asserted.

Finally, it works. 
Thanx guys.
Ok, I understand that I will fix my hardware that nTRST will act noninverting. The remaining question is, What’s about the nSRST line? Should this also act non-inverting or inverting like in the schematics of the openOCD documentation?
Thanks in advance,
Bernhard
nSRST should be inverting like it is in the schematic, only nTRST was faulty.
