How do you launch "Memory Test" in Nios ii EDS command shell

So I'm not sure exactly what was wrong, but I seem to have moved passed the memory overlap section. If anyone knows why that was happening don't hesitate to tell me, but I have figured out that when I use the nios flash programmer to convert my .sof file to flash and then program the flash file (hardware design) the dev board does not load it correctly. If I use quartus to convert my .sof file to a .pof file and program it that way it does load the hardware (nios) design correctly on power up. Basically programming the nios hardware design into flash with the nios flash programmer does NOT work and programming it with quartus as a .pof file DOES work. I don't understand why this is the case.
