sdram

Hello, 

 

I need some help with the nios 2 cores and the sdram controller for the DE2. I have gone through one of the online tutorials that explains how to interface the sdram thats on the DE2 board. 

 

ftp://ftp.altera.com/up/pub/tutorials/de2/computer_organization/tut_de2_sdram_verilog.pdf 

 

When i created the above system i wrote a very simple hello world program and everything works fine. Hello World gets printed to the terminal. 

 

But when i use Nios II/s core rather then the Nios II/e, the simple hello world program doesn't seem to run. i updated both reset and exception vector to use the sdram and updated the base address.  

 

 

The program seems to get loaded, although the program never prints out the hello world 

in the terminal. 

 

Why does the program run with Nios II/e and not Nios II/s?
