Hi Cristian,
> What are you trying to achieve ? If you want to just program the eMMC you
can do it easily with SAM-BA[1].
On our board the MPU boot from the eMMC boot partition, by exposing the
whole user partition as a block device we can modify the target system
easily, like modifying the partition table.
I've tested the gadget works well in Linux, but it's not possible to expose
the whole disk.
For reference I've implemented at91bootstrap eMMC boot partition support,
both at91bootstrap and U-Boot are inside the boot partition.
