Hi,
I am working on porting mainline U-Boot to a custom AM335X board that only has eMMC as the boot medium.
I can load U-Boot via serial boot and flash MLO and u-boot.img into the eMMC using DFU. Then the board boots successfully via eMMC.
Now I want to run the "ums" command to be able to mount the eMMC on the host. The problem I am getting is that when I select CONFIG_CMD_USB_MASS_STORAGE=y the board no longer boots.
Does anyone know why selecting CONFIG_CMD_USB_MASS_STORAGE=y causes the board to not boot anymore?
Not really ... I cannot see, which impact activating this command has with not booting ...
May some problem with image size? Early malloc space, some addresses which now overlap?
Good point. Just to avoid this scenario, can you make sure UMS is enabled only in U-Boot and not in SPL? or you can try with old MLO with new U-Boot :).
As Heiko already asked, can you provide more details in the failing scenario?
Thanks and regards, Lokesh
