if your OTA2 image already was uploaded to staged area successfully, then board will reboot to extract the staged image.
if you keep pressing reset key while extract , it will go to OTA2_BOOT_FAILSAFE_UPDATE:
you can see it from ot2_failsafe.c
if your running app goes to die and watchdog happens.
it will go to factory reset , the logic should need a confirm.
OTA2_BOOT_FAILSAFE_FACTORY_RESET should happen.
you can have a try to see if your evb turns into bricks with or without staged image.
The question has been resolved.
