jffs2 problem

[Wojciech Kromer]

I can't guess whats wrong with my jffs2.

My test:

sh-2.03# mount /dev/mtdblock0 /mnt -t jffs2
sh-2.03# cp ./vtxcsmod /mnt/lib/modules/vtxcsmod
sh-2.03# diff ./vtxcsmod /mnt/lib/modules/vtxcsmod
sh-2.03# umount /mnt
sh-2.03# mount /dev/mtdblock0 /mnt -t jffs2
sh-2.03# diff ./vtxcsmod /mnt/lib/modules/vtxcsmod
sh-2.03# umount /mnt

Then ... boot from jffs2 filesystem
Now:

sh-2.03# diff ./vtxcsmod /mnt/lib/modules/vtxcsmod
Binary files ./vtxcsmod and /mnt/lib/modules/vtxcsmod differ

?????????????????????????????????????????????????????????
Anyone could help???????????????????????????????????????

Maby this dmesg helps:
