hi there

I am using yaffs2 under linux 2.6.9 on EP9302 board, and there is a samsung nand flash K9F2G08(256M, 2k+64) on the board.

Now I can mount yaffs2 and create, delete file and folder, but when I umount and then mount it again, I can only find the last two file/folder there.

for example:

#mount -t yaffs2 /dev/mtdblock5 /mnt

#cd /mnt

#ls

lost_found

#mkdir 1 2 3 4 <=============here, I create 4 folders

#ls

lost-found 1 2 3 4

#cd ..

#umount /mnt

Now I will re-mount the yaffs2

#mount -t yaffs2 /dev/mtdblock5 /mnt

#ls /mnt

lost_found 3 4 <=============here, I can only get the last two folder

and, I have try many times and got the same appearance,The filesystem just only save the last 2 files/folders on my board.

btw, I have use jffs2 on the board, it works well except the bad speed.

So, anybody can give me some advice? I will really appreciate that!

Thanks in advance!

Joe
