Bionic image boot from SD

[pete]

I flashed Bionic onto the eMMC and now SD boot is no longer working.  I think the uboot is the issue, but I do not know how to go about fixing it.  Ideas?

Hey assuming you're folowing this guide: https://forum.pine64.org/showthread.php?tid=8119

Sounds like you needed step 6..



6. Now you have Ubuntu installed on eMMC and you can also boot from SD card, but only the same operating system. 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. From now on you should be able to boot also other OS from SD like before.

Download those files and run the script and then it starts working.e
