For your convenience copy'n'paste of my comments from [3].

You need to change mmc word (note that mmcpart word is left untouched) to raw
word in description of partitions. It's done, for example, in
do_dfu_alt_info_mmc environment variable.

Command is kept the same:
dfu 0 mmc 0

~~~
There is no rawpart keyword in DFU if I remember correctly. You need to use
mmcpart instead. I have updated above comment to accent on this.
