Follow-ups

--- Sonic Zhang 2008-12-29 23:07:45

If creates the jffs2 rootfs in linux by mount and copy instead of mkfs.jffs2,

the warning disappears.

A possible difference is that the mkfs.jffs2 doesn't generated CLEANMARKER node

in correct position. The other possible difference is that the jffs2 image

created by mkfs.jffs2 is smaller than the size of rootfs MTD partition.

--- Sonic Zhang 2008-12-30 01:11:09

This bug is confirmed to have nothing to do with size mismatch. The only

possible cause is the mismatch of mkfs.jffs2 and jffs2 driver in kernel

2.6.28-rc2.

--- Mike Frysinger 2008-12-30 01:29:18

i dont really think so ... the cleanmarker position is dependent on the flash in

use and we havent been tracking it at all for any board

--- Sonic Zhang 2008-12-30 01:57:50

Does that means the mkfs.jffs2 should understand the cleanmarker position for

different flash?

--- Mike Frysinger 2008-12-30 02:44:15

afaik, it means we need to add cleanmarker flags in each uclinux-dist board

config Makefile. Michael would know more, but i think he's on vacation atm ...

--- Sonic Zhang 2009-01-09 04:30:53

It seems this bug doesn't break the jffs2 filesystem on nor flash. JFFS2

regression test can still running to its end. Down its priority.

--- Michael Hennerich 2009-07-27 06:36:10

First of all - the warnings are harmless -

Some Flash Memory Technologies Devices require a specially structured JFFS2

filesystem image. Therefore additional flags for mkfs.jffs2 must be given during

the uClinux-dist build process.

We therefore added the MKFS_JFFS2_FLAGS variable -

From top of my head I don't know the erase block size of the 28F128 try:

make MKFS_JFFS2_FLAGS='-e 0x40000'

IIRC there is procfs entry that tells you exactly what the erase block size

need to be...
