It is possible, depending on SYSBOOT configuration to boot from the eMMC

boot partitions using (name depending on documentation referenced)

Alternative Boot operation mode or Boot Sequence Option 1/2. In this

'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to

||
|
|
set boot0 as the boot device.
