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
