Doing an online course, i’ve kinda screw up my MBR on my BBB eMMC and i’m unable to restore it.
I’ve managed to build a 5.10 kernel that boots fine from SD card.
I know there used to be a script that can be run manually from BBB shell that ‘copy’ the SD boot and rootFS to the eMMC but can’t seem to find it.
I have not managed yet to build a ‘flasher’ image, i would like to learn to do it from command line.
: invalid option
Any help appreciated.
