Fishing for Ideas......
I have a NAND base jffs2 file system which I create and load using standard
procedure:
1) mkfs.jffs2 \
--eraseblock=128KiB \
--pad \
--output=image.jffs2 \
--compression-mode=priority \
--no-eraseblock-headers \
--squash \
--verbose \
--root=myfs/
2) flash_eraseall -j /dev/mtd6
3) nandwrite /dev/mtd6 image.jffs2
4) mount -t jffs2 /dev/mtdblock6 /mnt/flash
The mount looks good all the files are happy.
After a couple of reboots I start seeing ECC errors. The more I reboot the more
and more ECC errors appear. Does this ring any bell with anyone? (Montavista
2.6.18 kernel)
