As to how... any serial app with Xmodem should work, I presume. If the transfer starts, chances are the image will run automatically. > Thanks, > > Jan Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
