[U-Boot] Unable to saveenv to MMC
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:

Thank you for any light that may be shed upon this error.
can you try to access the partiton from uboot?
ls mmc 0:0

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

I have no idea how your SD card is partitioned but I guess that with this command you are overwriting your FAT formatted partition.

Partitions are numbered from 1. So partition 1 would be mmc 0:1.
mmc 0:0 would require that there is no partition table and the FAT file system starts in block 0.
Please, check the value of CONFIG_ENV_FAT_DEVICE_AND_PART in your configuration. The default is CONFIG_ENV_FAT_DEVICE_AND_PART="0:auto"
With "auto" function blk_get_device_part_str() looks for the first partition that has the bootable flag set.
So to analyze your problem further please look at the output of
sudo fdisk -l /dev/<your_SD_card>
assuming that you use a DOS partition table.
Best regards

Thank you for any light that may be shed upon this error.
Thank you for the clarification. I've correct my issue by partitioning the MMC storage and formatting the partition FAT. Then burning the U-Boot Image to 8K in on the raw media.
