different memory size for "Nios II Hardware Development Tutorial"

Hi,

I follow the "Nios II Hardware Development Tutorial" on Cyclone IV GX development board and it run successfully.

Then i increase the on-chip memory size from 20KB to 64KB, and repeat the tutorial.

But when i run it nothing happen.

This is the last message in console:

"Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Processor is already paused
