I have the current uboot-pinebookpro installed on eMMC. It appears to prefer eMMC to SD - unlike the u-boot that came installed on the machine, along with Manjaro Linux, which would boot SD if present.
Would it be possible to get a u-boot somewhere that prioritizes SD? Possibly that old version from an older Manjaro release date?
(From pine64 org – "
At this time, the Pinebook Pro ships with a Manjaro + KDE build with u-boot on the eMMC. Its boot order is: SD, USB, then eMMC. ")
(I guess I could install tow-boot, but it would be kind of tricky, since tow-boot installs from a .img and I’d have to disable eMMC to boot that from SD. Further complicating matters, something about my hardware (?) causes u-boot to hang when I try to type in commands.)
