    Hi. First you have to get the right"Logic" in FPGA, I mean the good .sof file downloaded to FPGA through JTAG.

    Then you could download ELF.

    Could you precise your operations and detailyour error message ?

    Hello everybody,

    some years go by, but I have the same problem. I have bought an Terasic DE0 nano board (with a Cyclone4) and try to make this tutorial http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf (with all the requiered files from Altera homepage). Everythings more or less fine (I only got some warnings during compilation but no errors). I also donwload the .sof file successfully and close the programmer window.

    But when I try to run the count_bin as NIOS2 hardware, I always get the attached error!

    Please could anybody help me - do I forgot any library or include an important file?

    THX

    Hello everybody,

    nearly two years have gone but I have the same problem when I try to run the "binary_count" programm (http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf (http://www.altera.com/literature/tt/tt_nios2_hardware_tutorial.pdf)). The compiling in Quartus2web and the downloading of the .sof file were successful, but when I try to run the count_binary example on NIOS2 hardware, I got an error.

    I get the attached error message ...

    So, could it be, that there's an failing library or do I forgot to attach an important file?

    THX, Dominik
