[SOLVED] I'm wondering if the ESP32 can call a method right before it crashes

[GeorgeFlorian1]

Hello !

I am playing around with me-no-dev's ESPAsyncWebServer library and it doesn't work all the time.
If the ESP crashes for some reason, there's a chance that the WebServer will not work on the next boot, so I have to manually reset by pressing the EN Button.

That's why I was wondering if I can insert a server.reset() right before any ESP crash, hardware reset, software reset.

In case of a hardware reset, pressing EN Button pretty much fixes everything that went wrong in the previous iteration, like heap memory.
Also, it's easy to write server.reset() before ESP.restart().

But I have no idea what to do when it crashes.

Any thoughts ?
Thank you !

No. A crash per definition means the execution environment is unstable. If the ESP32 could happily continue running, there would be no reason for it to crash/reboot.

Probably its not what you are looking for, but in freertos you have stack overflow hook, which can be called right before crash (in 1 particualr case):
