    Hi

    I want to use tvp5146 for video capture with LogicPD Torpedo DM3730 Development Kit. I have a custom board for tvp5146 which connects to camera parralel port on development kit. 
    What should I do to get this worrking?

    I have already done these steps:

     > Enabling tvp514x in kernel . By using lsmod, I can see that the module is loaded.

    >  Enabling video4linux.  V4l2 is enabled but it says that there is no /dev/video0 device.

    I am looking to see if I can get my hands on a tvp514x to see if I can help you, it may take a couple days for me to get back to you.

    We don't have a module for running a tvp5146 video encoder, but we have some people in our services group that have experience working it.
    If you'd like, I can have someone in our sales department contact you about setting up a services contract. Would you be interested in that?

    Dear Adam,
    Thanks for your response. Actually, I have done several steps so as to get thin running but I didn't succeed. I need to talk to someone who knows what to do so that I can ask my questions.

    In your "logic/ltib/rpm/BUILD/linux/arch/arm/mach-omap2/board-omap3logic.c" file, you have support for mt9p031 camera. Now, how can I change this file in order to support tvp5146?

    Thanks in advance

    The best help I can give you is to point you to http://processors.wiki.ti...nd_Closing_of_driver

    The OMAP35 is a subset of the DM37, so the instructions are similar.

    When I built the stock BSP as we ship it, the TVP514X driver is enabled by default (not as a module) and the following devices appear:

    DM-37x# ls -l |grep video
    lrwxrwxrwx 1 root root 6 Jan 1 00:00 video -> video0
    crw-rw---- 1 root root 81, 0 Jan 1 00:00 video0
    crw-rw---- 1 root root 81, 1 Jan 1 00:00 video1
    crw-rw---- 1 root root 81, 2 Jan 1 00:00 video2
    crw-rw---- 1 root root 81, 3 Jan 1 00:00 video3
    crw-rw---- 1 root root 81, 4 Jan 1 00:00 video4
    crw-rw---- 1 root root 81, 5 Jan 1 00:00 video5
    crw-rw---- 1 root root 81, 6 Jan 1 00:00 video6
    crw-rw---- 1 root root 81, 15 Jan 1 00:00 video7
    crw-rw---- 1 root root 81, 16 Jan 1 00:00 video8

    Unfortunately, since the TVP514x is a device that is not part of the base evaluation kit, nor do I have access to a TVP514x kit, so I don't have a way to walk you through the steps to enable it.

    If you'd like to contract with our services group, I can have one of our sales people contact you.
