Did you remember to erase the flash first with:
erase /dev/mtd0
	Yes, I erased it in two ways:
		- by using the "erase" command
		- from the ppcboot.

JFFS2 question!

Hi,
    We have our own PPC750 board with 4 8MB(16 bits, sector size 64k byte)
AMD Flash chips on it. Currently we only use on chip, and try to make JFFS2
filesystem on it. We did pretty well on it.
    However, we have a question. When we try to copy a small file into the
Flash
memory, it always resides at the beginning of the last sector of the flash
memory.
Does that mean JFFS2 grow backward?
    Thanks.

Best regards,
Pei-Jie Hong
