Re: Questions on GDB
I am using gdb 4.18 with wiggler for mpc8xx on a win nt hosted system. I
am using cygwin tools and cross compiler for powerpc-eabi target.
I am able to connect to the target but unable to modify the registers.
When i try to set the processor for 860 my info registers command fails as
"read_bdm_registers : sr0 Invalid CPU register access attempt failed"
I see people taking about 'ocd reg' command for modifying the special
purpose. But this is not availabe in gdb 4.18. Is there a patch for it
