Which chip is it? Is it correctly recognized by the kernel (arch/ppc/kernel/cputable.c)? If not, it will choose a "Generic PPC", which might not have the correct attributes (for example, if it is a 8270, I think it is currently not recognized; the kernel would boot but the MMU would behave badly). > Once this happens my Abatron BDI-2000 is somehow hosed and can no > longer write to memory.

This is a silly question, but, did you try to unplug the BDI-2000 before running gdbserver?

Do you use a somewhat recent version of glibc, and was it built against a somewhat recent version of kernel? Can you also tell us the version of binutils and gcc ? Not all the combinations are reliable ;-) Regards, -------------------------------------------- Jean-Denis Boyer, Eng.
