Hi all
I've been trying to mount jffs2 file in AM335x evm board.
but, I am facing problem
jffs2 file is not rootfs, just font file.
I used to use to UBIFS file system
UBIFS file is ok
When doing boot an error message occurred
jffs2: mtd->read(0x5c bytes from 0x9d37a4) returned ECC error
but I can read font file (mounted jffs2 file)
just error message occurs
how can I fix this error message?
1. Hardware spec
- Board: AM335x evm board
- Nand : MT29F2G08 , 256MB (default nand)
2. Mtd-Utilities
- Site : http://processors.wiki.ti.com/index.php/MTD_Utilities
3. Compile command
# mkfs.jffs2 -lqn -e 128KiB -r FS_DefaultElements -o FS_DefaultElements.jffs2
# sumtool -iFS_DefaultElements.jffs2 -oFS_DefaultElements-sum.jffs2 -e128KiB
4. Partition
dev: size erasesize name
mtd0: 00020000 00020000 "NAND.SPL"
mtd1: 00020000 00020000 "NAND.SPL.backup1"

5. mount script
mkdir /mnt/mtd3_DefaultElements
mount -t jffs2 -o noatime /dev/mtdblock13 /mnt/mtd3_DefaultElements
6. Nand write (in uboot)
nand erase.chip;
mmc rescan;
