The vendor uboot worked well. =A0The generic mainline, apparently not so much. =A0It may indicate that the vendor didn't upstream everything. =A0I haven't worked much with the new imx6 uboot packages because for me they're completely unusable because they lack support for netbooting. =A0(If you feel tempted to say something about efi and netbooting, please provide links to how-to documentation at the very least, and an example that works for armv6 would be even better.) -- Ian
