Read only is read only is read only. There is no way to change the permissions to write to a romfs filesystem. By definition, it is impossible.

You need to read up on the available filesystems (perhaps, ramfs, jffs -- on flash, etc.), implement one of those filesystems.

If you're asking how to _change_ a particular file on a romfs filesystem, that is covered in the Microtronix-provided documentation. Start reading. :-)
