Hi Johi,

Thank you! for your reply. I have followed steps that you're mentioned above. When I'm trying to download .elf file to DE0 nano I'm getting an error saying that "Downloading ELF Process failed". I found that many people facing the same problem like me when they try to use SDRAM with NIOS. Do you have any idea why this is happening? Following are the console output when I'm trying to Upload the .elf.

Downloading 00800000 ( 0%)

Verify failed between address 0x000000 and 0x003107

Leaving target processor paused
