You should try using this patch: http://www.aleph1.=o.uk/lurker/attach/3@20070912.140012.12f2d093.attach And recompile your =kyaffs2img application. Here is an example after patching:  ------------=--------------------------------------------------------------------------=-------------------- # dd if=/dev/zero of=/tmp/test/file bs=10=4 count=512 # mkyaffs2image /tmp/test/ /tmp/yaffs2.img 2 # flash_era=eall /dev/mtd3 # nandwrite -a -o /dev/mtd3 /tmp/yaffs2.img # mount -t =affs2 /dev/mtdblock3 /mnt/ ---------------------------------------------=------------------------------------------------------------- Note: i= command "mkyaffs2image /tmp/test/ /tmp/yaffs2.img 2", 2 is offset of yaff='s information in OBB.
