Corrupted backtrace

Post by p_j » Thu Jun 23, 2022 2:12 pm

I am getting an intermittent crash on an ESP32-S2, the crash doesn't always happen at the same point and the backtrace is corrupted so I can't decode it.

Micropython is 1.1.19 compiled with idf v4.4.1

Has anyone seen this before? Are there any compile settings available to get more detailed crash info?

Thanks
