Ahh, I was under the impression that it tried to use u-boot from the SD-card, my bad.

For my purpose it would be nice to be able to “dualboot” OS’s by just using a SD-card with the wanted OS on it, and let the stock system be on the eMMC.

I’ll play around with it at bit and see if I can get it to at least load a kernel.

I guess that means that I need the extlinux way of things to get it going…
