This question has been asked and answered many times.
The image layout that you need to write to nand depends on many things,
including the OOB layout. For that reason, mkyaffs2image is not able to
create an image that will work for all NAND types, NAND controllers etc.
You will likely need to modify mkyaffs2image to work with your NAND set up.
