I have some code that ran fine when I used the SDK USB stdio. I then changed to TinyUSB and found that I had lockups when the code called functions that used timers. Thinking this was some error in the way I bolted TinyUSB onto my code I started with a solid TinyUSB example and bolted my code to that. I've ended up with the same problem. A stack trace of the two cores is here:
I'm currently removing all calls in core 1 to anything that locks up, as I don't have much running on core1, just a keyboard scanner. This is tedious, though, and I'd rather not do it, and I'd also like to know what is wrong.
Code:
