Oh, sorry, I should have been more precise.
You do not need the flash_erase or flash_erase_all. The rest of the
process is the same.

But anyway, JFFS2 is not a very good idea on a USB stick. The problem is
that the stick's flash controller already does wear levelling and error
correction for you, transparantly.
With JFFS2 you might end up with doing the process twice which might
result in even worse performance than with a "normal" filesystem, like EXT2.
You should be pretty safe with an ext2 if you mount it with "noatime"
option and if possible, read-only.
