AW: jffs steps from boot prompt to mount?

Check wether mtd0/1/... exits under you /dev directory. Probably they are
missing. You want to consider this two kernel options:

# CONFIG_MTD_CHAR is not set
# CONFIG_MTD_BLOCK is not set

The first creates mtd0/1/... and the second one mtdblock0/1/... which should
fix both of your problems. After you compiled in both options you should
erase all your partitions with eraseall. The erase command should work to,
but i did not test that. Then you can simply create an filesystem on your
device. If you want to use jffs simply do:

mount -t jffs /dev/mtdblock0 /mount

This creates a jffs filesystem on your partition. After the filesystem has
been created you can ommit "-t jffs" since mount now autodetects the
filesystem.

Hope that helps
