jffs2 with mtdblock

[Pering, Trevor]

Hello, I'm having trouble mounting jffs2 on a blkmtd device. The
sequence of commands is below -- am I missing anything? This is on a
arm-linux 2.4.19 kernel with jffs2 backported from 2.4.27. In the
sequence below, I also try to mount ext2 on the mtd block device just to
see if it works (and it does). And, we use jffs2 successfully on other
mtd partitions in the same system.

Any thoughts? (There are no significant messages in /var/log/messages).
Any way to tell what's going on?

Thanks,
Trevor
