Hello everyone!

I'm a newbie and I'm successfully experimenting with the ESP-MDF OTA.

I'm interested in the following function of the "Mupgrade" solution (https://github.com/espressif/esp-mdf/bl ... pgrade.rst):

Revert to an earlier version: The device can be reverted to a previous version using specific approaches, such as triggering GPIO, or cutting the power supply and rebooting for multiple times.

Is there any example to accomplish this result?

I'm looking for a solution that allows me to revert to the factory partition only toggling the power supply (without the use of buttons or commands).

Thank you in advance for any help!

Reverting to the factory partition by cycling power doesn't make any sense to me. Why don't you describe the conditions by which you wish to initiate a revert to factory partition. You could use this to decide whether it's a software reboot or a power up...

RESET_REASON reason0 = rtc_get_reset_reason(0);
RESET_REASON reason1 = rtc_get_reset_reason(1);

Maybe looking at the reset reason will help you.
