Hi Otavio, so I need to clarify my question: Does exists a method to store a u-boot bootolader in an unpartitioned unformatted eMMC (without kobs-ng, so without using linux), but simply running a command from u-boot? So in case I have only USB-OTG as connection method to my board I am forced to use MfgTools?
