Rakhi I have some good news. It seems that I need to add yaffs2 root fs support for a batch of boards we have just received that have the wrong nands on them (2k not 512byte) so forcing the issue. Over the weekend I will probably sort out some germinal bootldr35 and mkyaffsimage2 code and feed it both to husaberg and the list if I get the time. Watch this space. Nick
