as the RLink is pretty easy to disassemble, I can try helping with that
case. I suppose that the Primer1 sch is the one in the official
documentation, so I'll try to draw a sch of the real rlink. or maybe you
just need some specific info, maybe just the reset lines part?

that is very likely! the voltage on the SRST line is about 0.15V - not
zero! - so it may be some disabled circuitry.

write me what you need and I will provide whatever help that would be
required to make openocd better.

4\/3!!
