This would be really handy because in my case, my esp using it's serial for modbus RTU and no other PINS are available for monitoring the serial output of the crash logs, and in random times it crashes. Initialization of peripherals etc. Can Espressif please confirm this bug? I noticed another thread here with the same issue: ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. ESP. platform In the esp insights marketing, it says you can have esp insights upload the core dump logs to the cloud if there was a crash upon reboot. I tested both an ESP32 and an ESP32-S2 dev module - also updated to the latest version of arduino-esp32 (). I've double checked the When power on the board we expect to get POWERON_RESET (=1), but RTCWDT_RTC_RESET is reported (= 16), when calling to esp-idf rtc_get_reset_reason API. See description of extern "C" void app_main() { ets_delay_us(1000*1000); ets_printf("wakeup_cause=%d reset_reason=%d\n", esp_sleep_get_wakeup_cause(), Both using Arduino-esp32 directly or as an esp-idf component, the rtc_get_reset_reason() function doesn't return the real reset reason. After many trials (thinking it was to do with the 'Reset WDT' statement), I finally realised that it Wasn't tying up the early #define When I go to check Esp reset reason it returns brownout error, the reboot log shows SW_CPU_RESET.
