I downloaded the latest u-boot snapshot on 20120717, installed Sourcery CodeBench, set the CROSS_COMPILE variable, and compiled. There were no errors. When I try to load with kwboot it fails. If I build the same u-boot source on the target, Guruplug, with Debian Wheezy installed I get a usable u-boot.kwb.
