Hi, I working into the DE2-115 board. I want to save the Nios II program into the EPCS64 memory. (Save SOF content and ELF content into EPCS). I tried a lot of configuration that I have read in forum...

Hi frank2215,

Is your Nios processor using an MMU? If so, you will need to add the --mmu switch to your nios2-flash-programmer command line: nios2-flash-programmer --epcs --mmu --base=0x000021000 hw.flash --debug

If that doesn't work then are you sure that the Nios processor is even seeing the flash? Have you confirmed your base address is correct?

Just my two cents.
