if i can jump in, a good way to start playing is to configure and build for the "sandbox" architecture so you can run it on your x86 system. for the benefit of a couple friends, i whipped together a wiki page for that here: http://www.crashcourse.ca/wiki/index.php/U-Boot_sandbox very simple but enough to get you started, and you can match up running the commands with the underlying code. rday -- ======================================================================== Robert P.
