Dear Jürgen,

My code does some modifications in chipset registers. One of it seems the bad one and the cpu hangs when executing it. While I can't trace it, I have now disabled the modifications step by step and find the bad one (OPBA0_CR).
Does anybody knows something about the registers OPBA0_CR and OPBA0_PR (OPB Arbiter control and priority)? After reset it's contents shows illegal bit values (if I try to interpret the value after reset based on my 405GP manual).
And which CPU model is on your board?
Best regards,
Wolfgang Denk
