Hello,

    I am currently working on support for a Samsung 512 MB Nand flash.  The nandwrite and nanddump utilites seem to work correct on the device but yaffs seems to overwrite the bad block marker on the pages. It only does this when i turn on ecc support for the NAND driver.  is there a change that needs to be make in order for ecc to work with the yaffs.

Lance
