| Hi Sethu, Do you see the kernel errors before stepping through the code or when you hit a specific line? Regards, Mike | |
| Hi Sethu, I was able to reproduce the behavior you saw and discussed with our team. The behavior is considered normal because the DSP will enter a non-suspendable state after debugging, and Linux will complain when power management tries to put the DSP into suspend. Regards, Mike | |
