I am using an imx6 SoM from SolidRun. We have purchased a large number of these and mostly they work fine.

I tried to update to Fedora 25 and now a few of them won't boot. (most work fine)

All my SoMs are all supposed to be the same but some must be different. Both worked fine with an older version of Fedora

Is there any way to just force a boot from MMC1 with no checks?

I tried to update to the u-boot from Fedora 26 just to see if that would help. It does not.


This is what I get with the "bad" ones


U-Boot SPL 2016.09.01 (Oct 19 2016 - 14:40:29)
Trying to boot from unknown boot device
SPL: Unsupported Boot Device!
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###


The ones that boot correctly do this
