dd to the nand mtd will not work because it does not handle the oob area 
properly. Use mkyaffs for that purpose.

Also, you seem to be mixing yaffs (the original yaffs 1) and yaffs2

If you really want to be using yaffs2, be aware that the mkyaffs2image is just 
for guidance only. It will not always work with all mtds due to different oob 
placements.

Something like

  mkyaffsimage fsdir yaffs.img
  mkyaffs /dev/mtdblock/0 yaffs.img
  mount -t yaffs /dev/mtdblock/0 /mnt
