Description
Please enable the core dump and core dump to flash (#define CONFIG_ESP_COREDUMP_ENABLE) in the new Arduino SDK.
At the moment the function in #include "esp_core_dump.h" are only place holder.
Before Arduino edf core 3.0.0 the functionality was enabled.
I think it is very important to have this function enabled by default, so that when there are crashes in the ESP32 it is possible to dump the coredump flash sector and analise it.
The sketch provided below works perfectly with Arduino core 2.0.17, doesnt work at all (aka dump is FF FF FF.. ) on Arduino core 3.0.1

no debegu massage, just run the snipped on 2.0.17 and run it with 3.0.1
