Other Parts Discussed in Thread: TVP5147, TVP7002, TVP5147M1, DM3730

Hi all

I add tvp5147 driver to linux_psp kernel, I refer to the TI816x TVP5147 patch, and the tvp5147 can be detected. But the camera still not work.

I found 816evm tvp5147 work in vpss and VIP  instance by adding the sub-device driver . But I see the datasheet tvp5147 derict connect to cpu.

Should I regist 5147 to ti81xxvin_sub_device?

I attach the bot log.

    Hello,

    Just to clarify first: I think that on the DM814x EVM, you have to first configure your USBs to Host mode. Is that done on your board? I am sorry, if that is not the case.

    Hi sunny li,

    I also added tvp5147 driver to Linux kernel following TI816X TVP5147 patch (http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/191420.aspx).

    And I got an error below:

    =====================================================

    I thought there was something wrong with I2C. Have you ever seen this problem before?
    Please help me. Thank you.

    My evm board is: TMDXEVM8148 (Mistral) and I'm using ti-ezsdk_dm814x-evm_5_04_00_11.

    Hello,

    Please, refer to the following application note about how to add external decoders:

    http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver

    For capturing using TVP5147, you need to add the kernel driver for TVP5147.

    Best Regards

    TVP5147 driver is already avaiable as a part of Linux kernel under $Kernel/driver/media/tvp514x.c. You just need to hook this up to V4L2 capture driver.

    It would  be better to post the query in DM3730 forum, please:

    Hi,

       In the DM8168-EVM we got the TVP5147 working with V4L2, it could be useful in the DM814x too, you can find more info here:
