If you are writing raw image data to the mtd device via the standard mtd
driver then it wont work for two reasons
1) The image data contains oob data as well as "normal" mtd data.
2) It is not clear if you are writing to block 0 on the device. If so, be
aware that yaffs skips this block.
There was a mooted a while back for a utility to write images to nand mtd
devices but I don't think anything has happened. I am too busy right now but
I may get round to it later.
To do this, I modifies the bootloader and wrote the data directly to the
nand chip.

why is it like this?
