Now you should program the uboot to flash, with nios2-flash-programmer (or uboot itself).

So that uboot will start on reset.

Then you can use tftp from uboot to download linux image and run. Or you can program the linux image to flash and run it with a uboot script. You should not overlap those images both in sdram and flash.
