Well, if you read the help context carefully, you'll see that all your
attempts are wrong. And even if you don't understand the doc, googling
for nanddump would have lead you to [1] which has a working example.

So, the correct command is:

# nanddump -f /tmp/hsfw.bin  -s 0x01b60000 -l 0x00080000 /dev/mtd9

But please, try to search a bit before sending an email next time!

Boris
