Hi All, I allocated 3 partitions on my NOR flash. After Linux bootup, all paritions are found in the /proc/mtd. I verified the flash driver with "od -x /dev/mtdxxx". Do I have to use mkfs.jffs2 to format the partition before use it? Or I can just mount it as "mount -t jffs2 /dev/mtdblock0 /mnt"? Thanks, Mike
