Excellent, I guess that does make sense now. An equivalent of that change is included in patch 6/6, so that explains why you saw it fix your problem. s3c_udc also needs the change above, so I'll go send a patch for that. Thanks for testing, and it's great that we got to the bottom of this. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
