Linux with MMU on NEEK

Hi, Kazu

Thank you for your response, the problem has been solved by your advice. But the new confusion was that nothing appeared on the screen and Nano-X seemed running correctly:

/#  nano-X &
 686 nano-X
/#  nanowm &
 687 nanowm
/#  nxclock &
 688 nxclock

And the linux init messages is below

$ nios2-terminal
nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster ", device 1, instance 1
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)
