Nios systems - programing EPCS

Hello experts

I have build nios2 board and it work just fine - no problem with it.

But in software tools to many problems

So we are using command line to compile and download SW code to EPCS but

we don&#39;t understand how to download HW code to EPCS from command line http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

Can you explain or just show command line how to download HW+SW into EPCS ?

    Hi AlexS,

    > Can you explain or just show command line how to download HW+SW into EPCS ?

    for your sw elf file (sw.elf):

    $ elf2flash --epcs --base=0x0 --end=0x7fffffff --input=sw.elf --output=sw.flash

    $ nios2-flash-programmer --epcs --input=sw.flash --sof=<PGM>

    for your hw sof file (hw.sof):

    $ sof2flash --epcs --input=hw.sof --offset=0x0 --output=hw.flash

    $ nios2-flash-programmer --epcs --input=hw.flash --relocate --sof=<PGM>

    The <PGM> is the sof file for your flash programmer design.

    Regards,
