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?
You see absolutly no U-Boot output on serial? Do you have enabled early debug uart (if it is possible for am335x .. I can;t remember)
If so, you need a debugger, as it fails very early ...
So, you see .. no real idea ... I am sorry.
bye, Heiko
