Debugging fails with threads
Posted: Mon Oct 15, 2012 11:53 pm
Hello,
i've already posted this issue on the tracker but was directed here.
My setup
I have the following setup:
I'm programming for an embedded ARM target running ChibiOS/RT:
Software versions:
Now to the problem:
Debugging works great if i disable thread support in OpenOCD - basically it then only shows the current execution. But once I move to threads, it works fine - but if threads are destroyed (this happens for example when initializing the RTOS), codelight chockes on the gdb output.
Most probably this is cause by a parsing error of the "info threads" command, which is nicely illustrated in this screenshot: The corresponding lines from the gdb log:
Best,
MaBl
