On my Odroid C2 I cannot see the reported error.

The devices are numbered 0 and 1 and these are reported in your boot log.

Where do you select "MMC Device 2"? Do you have a boot.scr which tries
to select the wrong device number?

Please, provide the output of

mmc dev 0; mmc info
mmc dev 1; mmc info

Here is my boot log:
