PIneBook Pro - Boot from SD

[tophneal]

Thanks for the tips.  I updated via the command line because I don't have an 'update' icon in my tray.  (sudo apt update; sudo apt upgrade).  Still not booting from MicroSD.  The SD card is mounting with  "boot" and "linux-root" drives, so I know the card is seen and recognized.  It just doesn't seem to be selected as the boot source.  I am out of ideas on how to resolve this.

Again, thank you for your replies!

You might need to manually update your uboot. I'll see if I can dig up on of the links/posts already up.

Per Wizzard:

If we need also to boot other operating systems, we need to apply uboot fix. So download all the files from here https://github.com/mrfixit2001/updates_r...filesystem and run the mrfixit_update.sh script while running from eMMC.
