Honored Contributorok dude....
do you want program your external flash ... and use the fpga to do that??? or you want start the fpga with the program in you flash?? you dont need a paralel flash loader... you need to do a sopc with your system :cpu, jtag , tristate bridge, clock, cfi flash , clk_ref.... generate , instantiate, assign, etc.... and compile...... donwload the .sof goes to altera/nios2eds/nios2 command shell at your start menu (windows) and convert the file you want program to .flash and write the flash using nios2-flash-programmer....... i think that ..... explain better what you want to write to the flash...... cheers Franz
