Hi ....

I am using a NAND flash of 2K page size. when I go through mailing list I am able to know that some other users also faced the same issue.I'm mounting using following command after I have enabled following configuration in defconfig.

CONFIG_YAFFS_FS=y
CONFIG_YAFFS_YAFFS1=y
CONFIG_YAFFS_9BYTE_TAGS=y
CONFIG_YAFFS_YAFFS2=y
CONFIG_YAFFS_AUTO_YAFFS2=y
CONFIG_YAFFS_DISABLE_LAZY_LOAD=y
# CONFIG_YAFFS_DISABLE_WIDE_TNODES is not set
# CONFIG_YAFFS_ALWAYS_CHECK_CHUNK_ERASED is not set
CONFIG_YAFFS_SHORT_NAMES_IN_RAM=y

The commands I am using for mounting is

flash_eraseall /dev/mtd14

nandwrite -a -o /dev/mtd14 dummy.yaffs2

mount -t yaffs2 /dev/mtdblock14 /mnt/nand

i also tried

flash_eraseall /dev/mtd14

mount -t yaffs2 /dev/mtdblock14 /mnt/nand

But after that if I unmount and remount once more time the files I am creating will disappear.At the same time a new file will be creating in the folder lost+found,as name objXXXX.the content is still there in the nand flash.

I heard that there is some patch available for MTD device to make the yaffs2 working.Also I am using another nand of page size 512 bytes, Its working fine with yaffs1.

please help me to cure this problem..
