Good, it's blinking ! You're almost there. The unexpected pattern is probably a symptom of that subtle bug you still have to fix. A hint: put a breakpoint at address zero and see what happens. A few useful OpenOCD commands: Reset the CPU and halt it: > reset halt Put a breakpoint at address 0: > bp 0 4 hw Continue execution: > resume Single-step to the next instruction: > step List all breakpoints: > bp Remove the breakpoint at address 0: > rbp 0 For more complex problems, you'll want to use gdb, but for the ultra low-level things, like this one, just plain OpenOCD is often clearer. Now, it would be good if I could see the exact code that you're using. So this is a good moment for you to put it under revision control, either in git (see Andy's instructions) or our public SVN. - Werner
