Yes, i need something like this, as an application to be loaded instead
of the
kernel. Simple, to allow load for more than one option from flash or
from network
(simple tftp). I don't need write on the flash (CF) at this time.

Ok, but which is the "entry point" of the JFFS, that is, i need to call
the
functions to mount, or i can treat like a mounted file system, and just
read
the needed files? 
And, I can read from a CompactFlash card, if i'm using (after boot) the
MTD 
emulation? The CF is mapped as a hd device.
