This is an Odroid-X2. I'm booting from SD with a Sandisk Extreme. I
don't have any eMMC here.

Actually it was some other person who encountered this issue with his
Odroid-X2 and booting from SD. After he made me aware of it, I also
updated my u-boot (I was then using a version from May 2015, which works
perfectly btw) and encountered the very same issue as him.

For me it restores proper operation of the bootloader to the board.


With best wishes,
