Hi Artem,

>>Pardon, do you unmount JFFS2 before the erase :-) ?
 
Yes I did.

I think my strange prblem with the space of the partition is connected to
the msg that I receive after the mount command :

	/>mount -t jffs2 /dev/mtdblock5 /mnt

I receive the following msg:

	Newly-erased block contained wod xxxx at offset xxxx
	Newly-erased block contained wod xxxx at offset xxxx

Can you help me on finding the rason of this msg?

Many thanks!

Pardon, do you unmount JFFS2 before the erase :-) ?

The messages mean that JFFS2 issued an flash_erase command,
then read the newly erased eraseblock and found out it does
not have all 0xFFs.

Check that you are able to erase your flash corre3ctly. Try to dump the 
flash and see if it has all FFs just after you've erased it but before 
you've mounted JFFS2.

flash_eraseall -j /dev/mtd5 is definitely better by the way. Read the 
MTD FAQ why.
