Hi All, I am working on kernel 2.6.14.3. I could successfully include the YAFFS in to my kernel. I created a yaffs2.img file using the command "mkyaffs2image /my_dir yaffs2.img" after this I erased the flash using "flash_eraseall /dev/mtd1" After this I used nand write to write the yaffs2.img to /dev/mtd1 nandwrite -a -p /dev/mtd1 /yaffs2.img after this I mount the flash partition mount -t yaffs2 /dev/mtdblock1 /mnt1 and do a 'ls' ls /mnt1 to see only lost+found I then create a file using vi and edit the file I do an "ls" i can see the file and its contents. I "umount" the partition and mount again I again see only lost + found If I do a nanddump I can see the contents of all the files that I had written!!! Can anyone give me some pointers I have reached a dead end. Thanks in advance. regards, shivas __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
