JFFS2 is complaining that the partition you told it to mount is
essentially full of junk. JFFS2 is expecting there to be one of two
things in the partition that you tried to mount:Erased flash (which
would be full of nothing but 0xff bytes), or a valid JFFS2 image,
instead it's finding a bunch of data that doesn't contain the magic
values that uniquely identify a JFFS2 partition.
Are you absolutely sure that this is the right partition, and that you
put a JFFS2 image there?
Cheers,
Owen
