Also note that the eMMC is a device whose life is limited by the number of writes. If this is something that is intended to operate for multiple years, then you will need to limit the number of writes to the eMMC to the minimum necessary. If you really need a lot of realtime write updates, you might want to consider something like a small FRAM memory peripheral for the motor/control position memory, rather than the eMMC. FRAMs, since they are magnetic RAMs, retain the memory without power, with almost unlimited write cycle life.
