problem with debian emmc boot

[G4zCDzWb]

Additional info:

I have confirmed that the UUID mentioned in the serial output messages matches output from blkid command on another machine with emmc mounted. Also, just to be sure, I confirmed that the entry in fstab matches although I'm not sure if that is the only place where it is configured.

As for the 'common problems' section of the serial output messages:

I don't see any storage devices in the /dev output, and 'fdisk -l' returns nothing.
