Hi, 
I'm playing with jffs2 on NAND chips (Samsung 128Mbyte), MTD CVS is week old and kernel is 2.6.5.

I'm making image with 
./mkfs.jffs2 -b --eraseblock=131072 --pagesize=2048 -p -r /test_root -v -o test_root.img

and then copy it with cp (nandwrite seems to have problems wiht endianess). Everything work fine except on mounting filesystem I have messages:

CLEANMARKER node found at 0x00000000 has totlen 0xc != normal 0x0
CLEANMARKER node found at 0x00020000 has totlen 0xc != normal 0x0
CLEANMARKER node found at 0x00040000 has totlen 0xc != normal 0x0
....
and so on for every block.

Shoud I take care of that messages? What do they mean?

regards,

Andriy Korud

On NAND we store the cleanmarker (markes a clean erased block) in the out of 
band area. So the cleanmarker node should be omitted when creating the fs 
image. Add -n to the options

Cleanmarkers are not needed in jffs2 images that get written on nand, so 
create such images with --no-cleanmarkers option.
