c6678 - Kernel panic

Lorin Netsch

I am trying to run a program from the serial console that processes the same data multiple times. It works when processing through the data a few times, but for a larger number of iterations I received "Kernel panic - not syncing: BUG!" Do you have any ideas for what may be causing this or ways to debug?

I assume the program you are running is in user space. The error means the data corrupted in the middle of operation and Kernel does not have a way out of it. Do you think GDB will help to debug it? Please refer to the GDB wiki page in Linux-c6x Ecosystem Features.

The code that I wrote started multiple threads. The GNU tools seem to use a single threaded model, so as a work-around I changed my code so it does not use threads. That seems to have fixed the problem.
