Thanks a lot Freechip. It was solution of my problem. Unfortunately I have now compilation errors in Quartus, but I will try to solve this problem. As I wrote I have 256MB DDR SDRAM on my board. Nios can address only 256MB but you can change number of column address bits in DDR SDRAM Controller Megacore IP Toolbench from 10 bits to 9 bits. In that way only half of that memory will be used but you can add other peripherals to system and you won&#39;t have error "Address range of instruction master crosses 256-Mbyte".
