If mmc dev 1 fails, this will randomly rewrite or even damage some SD/MMC card that was selected before . Use && ...
Ok - good point.

Deduplicate these repeated commands.
Could you be more specific here?
Without mmc dev 1 and partconf I cannot access boot0 eMMC area. This particular board has the SD as mmc0 (rescue/devel) and eMMC as mmc1 (and eMMC is a production boot medium).
