ESP core dump

Have you come across these terms

"Guru Meditation Error"

"Stack canary watchpoint triggered"

and many more

But have no idea what it means !

Wait no further. This tool is specifically for you.

ESP32 serial log has a very strange way of specifying stack overflow and other exceptions.

The online tool https://maximeborges.github.io/esp-stacktrace-decoder/

helps in decoding the error by providing the call stack and the type of exception. Arduino IDE has a plugin and IDF Monitor has build in support to decode.

But what about errors in the field ?

All we need are the elf file and the dump itself
