So it should be straightforward to add support = for it. With 8-bit support, it should be a lot faster than a uSD card. = We'll see. Harumph. Looks like it always boots initially from the eMMC and U-Boot then looks at the boot switch to decide whether to continue from eMMC or uSD. This sucks: the U-Boot on the eMMC doesn't have ELF support nor API support so can't load and boot ubldr. Short version: The existing FreeBSD images for BeagleBone won't work as-is. At a minimum, we'll have to replace the U-Boot on the eMMC with one that has ELF and API enabled. I guess I'll be spending more quality time with U-Boot. :-/ Tim
