Fix for bad MLO on eMMC

Hi All,

I mistakenly put a bad MLO on the FAT partition of the eMMC. This means the board won’t boot at all, on power up there is nothing on the serial console and nothing happens. Since it’s not able to boot from that, the SD card appears to be useless also.

Any ideas how I can fix this?

Hold the boot button, press then release the reset button, then release
the boot button.

That should allow you to boot off the SD card and you can then copy a
good MLO file to the eMMC or reflash if needed.

Thanks Charles,

I tried that - i see CCC… on the serial line when I do that, which I believe means it’s trying to boot from UART0. I’ve tried a few different SD cards that I know are property formatted. Any ideas?

Thanks,
Chris
