KIndly share the detailed steps to revcover, I want to restabilize the board, then I will make my testbed to for further skillup.

Regards.

You ‘enabled’ the flasher on eMMC… So it’s trying to flash a microSD…

Grab an iot/minimal image… hold boot, force microSD to bootup, mount eMMC and edit uEnv.txt to not be flashing…

Regards,
