I personally haven't used second stage for a long time. For u-boot you need to copy the barebox image into the right spot (0x108000 for T20) and issue 'go' command. For barebox a 'bootm /path/to/image' should do, but I won't guarantee that I didn't break anything for second stage. > > Are you testing exactly this commit?
