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?
