Hi, Norbert, If you hit any key to stop autoboot when it says "Hit any key to stop autoboot", does it in fact stop the autoboot? If so, you could use u-boot's "printenv" command to see what commands get run as part of autoboot and then try to run them "by hand" to try to figure out where things go bad.
