Boot failure after running bbb-eMMC-flasher-eewiki-ext4.sh

I built a successful SD card to boot from as per: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black, but after running the eMMC script, the resultant boot fails from the eMMC (with the SD plugged in or not):

I’m now in limbo because I can no longer boot from either the SD card or the eMMC. Is there a way to overcome this issue?

We still only ship v2019.04 for beagleboard.org , for u-boot after that point you lose ethernet with the classic “board” method. I’d like to move to a later version, but still need to do a ton of testing on every BeagleBoard variant to fully support the latest u-boot release (which utilize a built-in device-tree).

https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Bootloader:U-Boot

Hold the “boot” button with your finger nail, insert power, once 1 LED turns on, you can release your finger nail… In that mode, it’ll boot off microSD… If your finger can’t handle it, that same i/o is on the header, just run a quick wire and gnd the pin. (it’s in the BeagleBoard SRM)

Regards,

I was able to use u-boot’s ‘mmc erase’ command (e.g., dev mmc 1, mmc erase 0 0x400) to clear the eMMC and boot back to my working SD card.

(Now back to figuring out why the eMMC script not worky)
