    6) Select File -> Update Boards

    I would like to make sure that the board is not the source of the problem.

    Please do not connect the USB cable to the evaluation board.

    7) Press Choose Board and select ADV7280_CUST.

    8) Wait for the board files to load. Note with the board disconnected this can take upto 5 minutes.

    9) After the board files load, the bottom of DVP EVAL window should say 'Board Disconnected' next to a red circle.

    10) Power up the ADV7280 evaluation board and connect the USB cable from the ADV7280 evaluation board to the PC.

    11) Press 'Hardware Reset'. The bottom of DVP EVAL window should now say 'Board Connected' next to a green circle. It should now be possible to program the ADV7280 evaluation board.

  • Followed instructions above and still not working.  I went through the other Q&A's on this problem and I don't see a resolution on them either.

    Also, from the Console output the error occurs in line 98 when mod.USBI2C() is called with a "Class not registered" com_error. In the Device Manager the Eval Board is connected as a USB I2C HID Device as expected.

    Additionally, if I run the DVP Eval's Device Scanner it hangs as well with the same error:

  • Hi,

      Please refer this FAQ to know about the DVP eval software limitation at DVP Evaluation Software to check whether we are missing anything.

       Also, in this pdf we have provided the details of downloading and installing the DVP Eval software,

  • I did get through the "Hang" with an install at a different location on my hard drive.

    Now it comes up with the 7280A Registers but I have no USB connection (Red Button: Board Disconnected). I have seen some answers to this same problem for installs on Windows 10 stating that Widows 10 is not supported:

     RE: EVAL-AD7147EBZ "USB communication failed" 

    Could you verify if the same is true for the 7280A Eval Board? Here's my screen with the Application Up and a console output when I do the Device Scanner. A window pops up for a second saying "No USB Connected" as well. The board does show that it's up with the USB HID and USB Interface drivers in Device Manager.

  • Hi,

      As Stated, DVP eval software can support operating system on Windows7/ WindowsXP at  DVP Evaluation Software  So could you please try the same on Windows 7 and then will track the issues on Windows10.
