3 years ago I think In above example I put the wrong WiFi password. If the ESP then reboots into config mode that happens.
Now I have tried to clear the EEPROM to try with the fallowing command:
IAS.preSetWifi("BackupWIFI","BackupPW");
When IAS.preSetWifi is called the CPU reboots with the following error. Looks like EEPROM issue, in this case it is CPU 1 that crashes. When rebooting in Config mode it is CPU 0 that crashes.

Rebooting...

Hello Onno, I get this reboot sequence on some of my ESP32, seems something maybe interfere with OLD SPIFS ? I then load the example Blink from Arduino on this board and I still get the same problem.
Problem: When Config mode entered, as soon as I try to use my smartphone (Sam Note 9) to connect to the WiFi AP "iasblink-912" the ESP32 reboots and the terminal shows the below log.
I am using ESP32-Wroom-32D
