I've been having some issues with single stepping, but am making a bit of progress. 1/ I started with a mips gdbserver port kindly supplied by Martin Rivers. It mostly works well but had some problems single stepping through conditional branches (the problem may have been due to a different target than Martin was using, or me... I am kind of new to this :) 2/ Previously I've had some luck single stepping kernel and module code with the kernel gdbstub (arch/mips/kernel/gdb-stub.c), so I ported the relevant single stepping code into gdbserver. The results were much better. The only thing that seems to be wrong now is stepping over function calls isn't working quite right. I can step into functions OK though. If you're interested I'll let you know how I get on over the next few days. If not, I won't be offended :) Best regards, Ian
