Guru Meditation Error: Core 1 panic'ed (StoreProhibited) (only crashes when function invoked from ISR)
Posted: Thu Sep 14, 2023 6:17 pm
When I call the function below from an ISR, I'm randomly getting
Guru Meditation Error: Core 1 panic'ed (StoreProhibited)
It might run fine for 30 seconds, or 10 minutes before I get the crash.
When I call it from loop(), it appears to work fine.
I need to call it from my ISR because I'm doing a median filter on some timing values from an external interrupt.
Backtrace info and function are below.
Thank you for any assistance you can offer !
