Thank you very much, it enlightened me a lot. I was able to understand the problem, now develop a solution.

Sounds like that ISR is marked as being entirely in IRAM while in fact, it's not. Hard to say without the full error or the code.

Do all sub-function calls also need to be in IRAM?

For some time I've been trying to solve this problem and I can't, the fact is. I have an esp32 saving settings, and it gets an ISR from LoRa. Despite semaphoro deals, apparently, the act of happening the ISR while manipulating the flash is a problem. Any suggestion? PC: 0x40008150 EXCVADDR: 0x000000...
