You should be using jffs2, not ROMFS. ROMFS is not writable.

Also, you say 
"Application images, eCos Kernel"

You have the wrong idea here. eCos is statically linked to the
application, not a seperate thing like Linux. Also, eCos is quite
happy to run without what we call the kernel. ie you can run eCos with
just the HAL and the device drivers. The normal redboot configuration
for example does not have the kernel.
