I recommend creating a test hardware project that contains a Nios II 'f' core, a DMA called "dma", JTAG UART, 64kB on-chip memory, and the SDRAM controller. Run the test program called "memtest" from the on-chip memory and use it to test your SDRAM to make sure it is operating correctly. You'll need to connect the CPU data master and both DMA masters to the SDRAM controller for this test to work properly.
