    I just tried - the problem remains, but what is interesting:

    Correct values (driver):

    dsp_area[0]=91ba
    dsp_area[1]=bc00
    dsp_area[2]=eb17
    dsp_area[3]=2643
    dsp_area[4]=54cd
    dsp_area[5]=5405
    dsp_area[6]=91ba
    dsp_area[7]=49c2
    dsp_area[8]=1f61

    Wrong values (application):

    kadr[0]=1c59
    kadr[1]=5405
    kadr[2]=1f61
    kadr[3]=49c2
    kadr[4]=49c2
    kadr[5]=eb17
    kadr[6]=1f61
    kadr[7]=2643


    It's looks like application has some correct values but it's kind of mess.
    What else could be wrong?

    Thank you very much
