It’s been quite a time I have my BPI M5 and took one for my dad to setup a pihole server. With time and many changes his was not running for quite a time and when we wanted to put it back in service, we lost the root password (and other users too).
I tried to start with a freshly made SD card and I can’t boot on it. I searched on the forum if people had similar issues but none of the solutions I’ve found suit my problem.
How do I wipe my emmc without any cli access ?
Thanks for your help !
