Ok thanks. I currently have this: uenvcmd=load mmc 0:1 0x82000000 /boot/uImage; load mmc 0:1 0x88000000 /boot/am335x-boneblack.dtb; bootm 0x82000000
But as yet it's not working. Unfortunately I don't ahve the serial debug cable with me so I can't see where it is failing, hopefully I will have this tomorrow and see what's going on.
