I know that this may seem like a pointless exercise, since the u-boot binary for the UDOO board is already provided in the Downloads section of the website....But would it be possible for someone to post the procedure for building U-Boot for the UDOO boards ? Also are UDOO boards supported in the mainline U-boot yet ?
I don't know if udoo team will want release uboot source, I think they will do it in the near future. There are some rumors that a guy is working on uboot 2013 for udoo, look here http://u-boot.10912.n7.nabble.com/PATCH ... 64161.html
I've build and booted the u-boot-2013.10 linked to above, it works, but U-boot doesn't yet know about the eth PHY, so there's no networking in U-boot. I didn't yet boot test from MMC using their mainline kernel. I will probably get there eventually. I'm curious as to where the U-boot sources are/went? I cloned them the other day, with the hopes of cross-compiling for myself, but the github repo has since been removed. The image I did manage to build is slightly smaller from that of the binary available on the downloads page, so I'm thinking there might be some differences from the source that was posted.
