Re: Booting CURRENT from PinebookPro SD over 10-RELEASE on eMMC

[Matthew Widup <widupmm%proton.me@localhost>]

Hello Joel,

Are you able to boot a different operating system from SD card?  Manjaru, Debian, or NetBSD 10-RELEASE?  If so, most likely your image isn't bootable.

Otherwise, disable the eMMC and see if it will boot; then most likely you could replace the U-Boot on the eMMC with a different one.
