Are you using a device-tree-aware u-boot with uImage, or are you using cuImage.pq2? Do not use dtbImage.ep8248e; that's for PlanetCore. ep8248e in mainline u-boot doesn't appear to be device-tree aware. If you're using cuImage.pq2, do you get any output from the bootwrapper? Make sure you add /chosen/linux,stdout-path. There may be other device tree changes you need to make it work with u-boot as well. -Scott ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
