Boot problem DE2-70 mmu

Hello, 

 

I have a problem to boot the Linux kernel with MMU on DE2-70 board. 

I changed the design in SOPC followed instructions at http://www.alterawiki.com/wiki/creating_a_nios_ii_design_with_an_mmu 

 

However the Linux isnt booting. Bellow is output from console 

 

bash-3.1$ nios2-download -g linux.initramfs.gz;nios2-terminal.exe Using cable "USB-Blaster ", device 1, instance 0x00 Pausing target processor: OK Initializing CPU cache (if present) OK Downloaded 5277KB in 92.0s (57.3KB/s) Verified OK Starting processor at address 0xC4000000 nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster ", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) 

 

then nothing happen 

 

Attached is also my SOPC design - I modified one from the demonstrations 

 

Any idea what can be the problem? 

Thank You
