- Mon Apr 25, 2022 11:46 am #94371 Couple of suggestions:

1. Do you know how to use the ESP Exception Decoder? - It will allow you to cut an paste that core-dump into it and it'll give you a more useful, human readable clue. Often pointing to your line of code.
2. I did not go through your code... but the error: ISR not in IRAM! means you did not decorate a callback method with IRAM_ATTR attribute that MUST have it decorated... Interrupt callbacks functions are one example.
