[U-Boot] Unable to saveenv to MMC

[Robin Polak]

Hello.

I'm having trouble persisting my environment variables to the SD Card
onto which I have FAT formatted and then written U-Boot to using the
following command:

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/disk2 bs=1024 seek=8

I get the following error when booting a Linksprite_pcDuino3_Nano with the
SD Card I've built:

How would I go about validating whether I can access the partition from
u-boot?
