I'm running a bdi2000 (with mpc85xx-gdb f/w 1.03) with a mpc8560ads target, and I'm trying to set breakpoints early on in linux startup (in the head_e500.S code that sets up tlb's). I'm setting the breakpoints from within the bdi telnet interface.
I can: --succesfully hit a breakpoint set up to any instruction <= the address of the first 'tlbwe'. --single step (with the bdi "TI" command) past that 'tlbwe' as far as I've cared to try I cannot: --hit a breakpoint once the first 'tlbwe' has executed. If I attempt to do so, linux startup doesn't proceed, I lose further communication with the target and the BDI claims "COP Freeze" and I have to reset the target. Btw, the 'tlbwe' in question marks invalid the first tlb1 entry setup by u-boot, which pointed at flash address space. Code is running out of ram at this point. I'm probably missing something very basic here. Any ideas? Thanks, Kylo
