Corrupted backtrace
Posted: 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
