DM3730 no input video device

Other Parts Discussed in Thread: DM3730, ADS7846, TVP5150

Hello,

I'm using DM3730 module from Variscite and I need to capture video from parallel camera port (ISP) after DS90CR288AMTD deserializer.

I'can play video files using these commands:

gst-launch playbin2 uri=file:///test.mp4 flags="native-video"
gst-launch -v videotestsrc ! testdisplaysink2

but I can't capture video (using x4lsrc for example). There is no any /dev/mediaX or /dev/v4l2_subdevX devices. I have only /dev/video1 and /dev/video2 devices.

I use linux-2.6.32-psp03.00.01.06.sdk kernel.

There is my bootlog:

    Vitaly,

    Have you enabled capture drivers in kernel config? Also do you have driver for the capture interface where the data is coming through the deserializer?

  • 0 in reply to Renjith Thomas

    Thanks for your reply, Thomas.

    We use video camera which generates 8 bits bayer per pixel image. Using four LVDS channels it is connected to DS90CR288AMTD deserializer. Вeserializer's pins are connected to these camera port's pins:

    CAM_D0, CAM_D1 ... CAM_D7 - 8 bits for each pixel data,
    CAM_HS, CAM_VS - vertical and horizontal synchronization,
    CAM_PCLK - clock.

    We a going to replace our camera with FPGA which will generate the same bayer video stream in future.

    There is configuration of kernel:



    As i can see - there is no any video decoders on the last screenshot, maybe I should select one to capture bayer or, if it is not possible, simply grayscale image.

    Best regards,
    Vitaly

    Vitaly,

    This configuration is not sufficient. It will not load the TVP515x driver as it will not be able to probe and find the device. Effectively there wont' be any camera capture driver loaded. 

    What you've to do is to write a small driver for your camera/FPGA and include it in the kernel and make few more modifications to add to your board file.

    Thanks, Thomas.

    Do I understand correctly that adding Texas Instruments TVP5150 video decoder from the last screenshot and recompiling this kernel sources will not be enough to probe and find capture device?

    Is the most correct way to solve my problem is to write my own driver similar to any fairly simple driver in kernel' sources? May be you could recommend me any standart simple capture driver to explore or any documentation?

    Best regards,
    Vitaly

    Vitaly,

    Since you don't have TVP515x physically connected on the board, it will fail during the probe function when it tries to do a I2C read. If TVP5150 is present, then it will succeed. 

    You can start writing your own driver by taking a simple driver from Analog devices or TVP5150 as an example. I'm not sure about the availability of documentation.  You can also refer V4l2 specs.
