    Q:

    Product    
    DM3730 / AM3703 Torpedo + Wire
    Software OS    
    Linux
    Part Number    
    1021753
    Description    
    Hello,
    I am currently working on an NTSC video capture device that takes NTSC data from the ADV7180_LFCSP32 and supplies 8-Bit, 4:2:2 YCrCb[7:0] output data to to the Camera Connector (J6) on the torpedo development board. I have connected the ADV7180 LLC pin to the CMA_PCLK pin and HS and VS to their corresponding inputs on the connector. I have modified the ADV7180 driver to work with the media control framework and I am able to configure my pipeline as follows:
    sensor -> ccdc -> memory
    I launch GStreamer using:
    gst-launch v4l2src device=/dev/video2 ! 'video/x-raw-yuv,format=(fourcc)UYVY,width=720,height=480' ! tidisplaysink2 mmap-buffer=true

    No error is returned and the everything seems to be working but there is nothing on the display.
    I would expect that at least some output (even if it is garbage) would show up on the display but I see nothing at all.
    Is there a driver for the ADV7180 and board support code enabling the driver to work in the Media-Control Framework?
    Are any NTSC encoder chips supported as a development platform to work in conjunction with the Torpedo development board?
    Are there any resources that can get me started and moving in the correct direction?

    A:I have a few questions:

    1. Do you see anything on the display through the boot phase?

    2. If you don't then test the screen in U-Boot to make sure that it is working?

    3. If you do see the screen working and then it goes blank, have you disabled the LCD blanking timeout?

    4. Do you see any output in the terminal that seems related to the issue that you are having?

    5. As far as support for the ADV7180, you can see what we have tested and how we have tested it in the Software Test Plan and in the Test Plan Log [1]

    6. For the NTSC support check the Software Test Plan and in the Test Plan Log [1]

    For additional resources there are many on the web [3] and we also have a section in our Linux User's Guide [2].

    Hi,

    I have the following output when I run "media-ctl -p" after an attempt to implement media-controller framework on adv7180

    - entity 16: adv7180 2-0021 (1 pad 1 link)
    type V4L2 subdev subtype Unknown
    pad0: Source v4l2_subdev_open: Failed to open subdev device node

    -> "OMAP3 ISP CCDC":0 []

    Not really sure what is wrong here.
    Is it possible to share your code changes on adv7180 as well as the board file?

    The person who did that work left the company before I started working here. I don't know where to find his work. I am waiting for a colleague who worked with him to return from Thanksgiving holiday. I am hoping to have more information for you next week. Sorry for the delay.

    Hi,

    I have encounter error with yavta when opening stream.
    I am trying to pipe adv7180->ccdc->ccdc output and use yavta to test, the following is some of the output I captured:

    DM-37x# media-ctl -p

    I am not sure I can be of much help. Steven no longer works here and that project was canceled by the customer. I ask someone who worked with him, but we no longer have the ADV7180 hardware available to us to try.

    I have one more person I can ask, but he is working off site at a customer's location, so I do not know when he will be able to respond. I'll update when I have more info.

    I talked with the off-site developer. Could you send us the logs for the media-ctl instructions you are using to configure the hardware pipeline? He would also like to see the output of "media-ctl -p" BEFORE you run yavata.

    Hi adam,

    I believe there is some issue with my pipeline source, most likely at adv7180 driver level

    The following are the logs for the media-ctl instructions used:

    Hi adam,

    Is possible to check with you what is a suitable pipeline if I simply need to capture image to file.

    The following is what I have been trying to use.
    DM-37x# media-ctl -v -r -l '"adv7180 2-0021":0->"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
    DM-37x# media-ctl -v -f '"adv7180 2-0021":0 [UYVY2X8 720x576], "OMAP3 ISP CCDC":0 [UYVY2X8 720x576]'
