Hi,
Once the main hardware init part is done, system idles for a while and then I get a hardfault (APP_ERROR_CHECK returns fatal)
I reset the chip, and asked it to continue. When I got "Fatal" in the log window, I hit Ctrl-C to give me a prompt, and then looked at the backtrace. Please suggest if there is a better way to get the backtrace.
(gdb) mon reset
Resetting target
(gdb) c
Continuing.
^C

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
What could be the possible causes ? Since the issue happens to be in files I did not modify, I'm not sure how to proceed further to debug.
