    I have worked on this long into the night… It turned out problem was in programming cable length. I have shorten it from 5 inch to only 2 inches and it helped to establish solid connection with micro controller.

    I have load the loader after which it was possible to load latest firmware 🙂 Pretty stupid issue, I must admit :o)

    Thx for hints

    I already tried this method and it failed. I pressume problem is that there is not boot loader on the board, because led is not flashing uppon reset.

    I followed procedure for uploading boot loader from wiki and now I’m really stuck: either my AVR Dragon or the board are dodgy. I can read uC ID, write fuse bits but every time I write something to flash and tried to verify it, it fails. Tried both AVR studio 6.2 and 4.19, same behavior.

    Board now lights only blue led upon startup – $100 brick at the moment 🙁
