Got it, thanks :)
In the "YAFFS Development Notes" , I got this information "Currently each
chunk is the same size as a NAND flash page (ie. 512 bytes + 16 byte spare).
In the future we might decide to allow for different chunk sizes. " Because
of my carelessness I thought it's talking about YAFFS2, my undoing.
