Not exactly sure why I think so - perhaps that was what I ordered... And I really think the ones connected to automated test setup at the office are Rev-C. Now that I tried to verify this - The one which I used to reproduce this issue (and now verify the patch from Tony) at home, seems to have say "PCB Rev6B" on PCB. However the u-boot says: => printenv board_rev board_rev=00C0 => but I have no idea where the environment variable comes from... Maybe a stupid question - how to find out the exact revision? Best Regards Matti Vaittinen
