Hi Robert, Do you have any pointer to steps for partitioning it as ext4. The link I followed specifically mentioned that partition type must be 'FAT'. The content of uEnv.txt as provided there is mmcdev=1 bootpart=1:2 mmcroot=/dev/mmcblk1p2 ro optargs=quiet
Would it remain same if partition type is 'ext4' or some values would change?
