Hi,
We are facing the following issues in DM355 based design .
1)
Unable to mount jffs2 . Its hanging ....(
# mount -t jffs2 /dev/mtdblock5 /mnt/nand/
jffs2_check_nand_cleanmarker(): Cleanmarker node not detected in block at 000000

2) If i do yaffs2 , its mounting .But it is not storing any data into flash....
Example:
mount -t yaffs2 /dev/mtdblock5 /mnt/nand/
cd /mnt/nand/
ls -> lost+found
mkdir test
ls -> lost+found test
umount /dev/mtdblock5
mount -t yaffs2 /dev/mtdblock5 /mnt/nand/
ls -> lost+found
Not able to see test dir
3) If we use large file system (cramfs - 80MB ), we are getting huge number of bad blocks. How to avoid that?
3) Can we use nand scrab command?
