I am confused. &#956;Clinux system is without MMU, How can I add MMU to the project?[/b]

If you have a Quartus Version >= 8.1 or so, you can add an MMU to the NIOS CPU. But beware, MMU-based Linux for NIOS is not publicly available (yet),

I don&#39;t understand the relation of this question to the original post. With Linux you always should write portabnle software. i.e. to access hardware from user land you should write Kernel I/O-drivers or at least use uio. see e.g. http://www.nioswiki.com/accessing_hardware..._space_programs (http://www.nioswiki.com/accessing_hardware_registers_from_user_space_programs) .

File i/o is not related at all.
