WebArduino - Home WebAug 22, 2024 · If a crash has occured the ESP32 keeps on rebooting. So storing values into flash will quickly wear-out the flash-memory (I had 33000 reboots over night) For narrowing down the problem I would like store data into the RTC-RAM. I did some tests but the data in RTC-RAM gets lost over a ESP.restart() or a resetbutton reboot.
