Charles,
Thanks for your response.
The YAFFS2 image has a sequence of 2K data chunk followed 64 bytes
of tag/metadata. For 2K page that have access to spare area, this can go
into single page main + spare area. But for 512 byte page NAND device,
how do we need to write this 2048+64 bytes.
I understood the mounting part as you have mentioned in the mail,
we are using boot loader to write the image and would be interested to
know how this data needs to be written on a 512+16 byte page NAND device.
