Re: Debugging threads

Hi Uwe,

I remember we had a similar discussion quite some time ago. If I
remember correctly, someone just wrote Nut/OS for gdb some (long) time
ago. But I'm very unsure...

I think you'd need a tracing solution. If the debugger stops in the idle
thread you'll quite likely be in the idle thread, which means that your
code waits for something (for some data on a socket or uart, a mutex, a
sleep, etc.) an no other thread is runnable.

So you ideally need to trace back your code path into the past to see
from where you changed into the idle thread.


Best regards,

Ole
