How to flash fpga and NIOS2 design ?

HI,

I have a DE2-115, i want to finalize my design on FPGA.

How do i store my hardware and software design into de2-115?

I've created EPCS controller, tristate bridge, CFI controller, and make the reset vector to EPCS controller. (see attached)

I've also managed to create .flash file from .sof and .elf using flash programmer GUI

I'm getting error(see attached) when i want to program these .flash file into DE2-115.

What am i missing? flash offset? what is it?

Since i have 2 non-volatile memory option. How should i use them? EPCS for hardware ? and CFI for software?

or CFI contain HW and SW ?

Please help.. Thank you

Regards,
