    Hi, Anand

    We have solved all problems with hardware right now (please read log in my second message). The only problem

    is that quartus_pgm --nios2 crashes with access violation after successful programming. This problem is also

    present in Quartus 17.1 with the same trace message.

    As a solution, I've moved from using quartus_pgm with --nios2 flag to JIC-file based programming flow.

    I've composed JIC-file with SOF data, Nios II program, DSP program and custom settings.

    And it works perfectly (erasing only modified regions) and programming succeeds every time.
