Hey

Before you can load your application into the flash, you indeed have configure the FPGA first. You can do this easily in your QUARTUS 2 software off course.

QUARTUS 2 >> TOOLS >> Programmer

Just scan for devices and load your FPGA .sof file into your corresponding FPGA.

Now, a volatile FPGA configuration is loaded into your FPGA by JTAG. After power down this configration get lost. So, therefore you have to store your fpga data into a non-volatile memory such as your CFI flash.

So, after you have loaded the .sof file you will be able to use the nios2-flash-programmer command.
