MicroPython 1.11 panic'ed

Post by msinn » Sat Oct 05, 2019 8:50 am


last night I got a panic from MictoPython on a ESP32 board that was connected via to a Mac. I have no idea where it came from and what to do about it.

Code: Select all

Guru Meditation Error: Core  1 panic'ed (Unhandled debug exception)

Backtrace: 0x400803c0:0x3ffc1e80 0x7ffffffd:0x00000000

After rebooting, the following information was displayed:

Then boot.py took over and the board beaved normal afterwards.
