I use (a pretty old version of, but I doubt that matters) RPi Foundation's Raspbian image, and compiled the kernel and U-Boot according to: http://elinux.org/index.php?title=RPi_Upstream_Kernel_Compilation&oldid=351104 http://elinux.org/RPi_U-Boot _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
