Re: ASSERT failure in USB HID

Hi Joe,

I try USB HID sample on my 96b_carbon with ASSERTs enabled and it fails with a different error.

***** USAGE FAULT *****
Executing thread ID (thread): 0x20000938
Faulting instruction address: 0x8001e82
Division by zero
Fatal fault in essential thread! Spinning...

I added developers mailing list to give greater visibility to the problem.

Hey Yannis,

first of all, thanks for the support on the Zephyr Mailing List the last weeks. I don't want to spam the list too much, that's why I'm writing you directly. If you prefer to keep the questions on the mailing list, I am happy to do that.


Now my question: The USB HID configuration works perfectly fine (I basically simulate a keyboard). But if I enable ASSERTs my program (and also the USB HID sample) fails during boot with following log:

Would you be so kind and try to run the sample on your boards with ASSERTs enabled? Just to find out whether the problem is on my custom board side or not.

Thanks a lot and best regards,

Joe
