Other Parts Discussed in Thread: TVP5158

hi,
I am working on ADAS Surround View Project in Automotive Domain.
I want to know some additional information about the Multides Surround View Kit.
1) Can we connect the cameras to the 'Video In' port ?
2) Is any additional hardware required to connect cameras to this port ?

    Hi aniket,


    Yes the multides kit can be used to connect up to 6 cameras to the video in ports.

    For this, you'll need the TDA2xx CPU board + Vision Application card + Multides surround view kit

    TI software supports this hardware platform and has sample applications which work out of the box on this platform.

    Regards,

    Thanks for your reply Nikhil.
    Currently I have DRA74x Jacinto 6 board not TDA2xx.
    in DRA74x Jacinto6 application board (JAMR3) we have TVP5158 chip but I couldn't find any drivers related to TVP5158 chip in Kernel Configuration 3.14.
    How can I download TVP5158 drivers so that I will be able to connect my camera in Video Input port (VIP).
    If you have any driver related links, please send the same.
    THANK YOU.

    Regards,
    Aniket. B

    Hi aniket,

    The default kernel already has support for the TVP5158

    We have mentioned in the software developer guide about the detailed steps to run the capture usecase from different cameras.

    Please follow them.

    The tvp5158 kernel driver is already part of the default kernel (comes as part of the installer)

    Thank you Nikhil,

    Yes, I got it confirmed about the Kernel support.

    I have some further querries and here it goes:

    -> I am using TI JACINTO 6 with JAMR3 application board. here am using GLSDK .3051.Boot-msg.zip

    JAMR3 board is getting detected. The procedure is followed as below:

    Capturing through TVP decoder

    Linux kernel supports TVP5158 NTSC/PAL decoder.

    TVP5158 decoder is a TI chip which can decode upto 4 channels of NTSC/PAL analog video and multiplex it.

    Video capture from 1 channel TVP5158 can be verified as follows.

    • Connect analog camera to the Vin1 port of the JAMR3 board

    • Change the SW2 switch setting on JAMR board as SW2[1-2] = [OFF, ON] - This is to select i2c4 for the IO expander

    • Reboot the board and enable i2c2 as given above

    • I2C device on Bus 2 slave address 0x58 should be probed successfully

    • VIP should register a V4L2 video device (e.g. /dev/video1) using this i2c device

    • Run dmabuftest with capture format of the analog camera (e.g. '720x240@YUYV')

    “Reboot the board and enable i2c2 as given above “ was given in glsdk manual. But i couldn't find any i2c2 settings in the manual.

    By following this we can see “/dev/video0 /dev/video1 /dev/video2 “, without even connecting camera to input video port of JAMR3 board. If we connect camera, its not getting detected.

    Below are the messages.

    Hello,

    This is beacuse the i2c4 is not getting probed

    TVP device has a dependency on i2c4

    i2c4 has dependency on the switch on the JAMR board

    Please make sure that your JAMR board has the i2c working

    Run following

    i2cdetect -r -y 3 and you shall see some i2c slaves on the i2c4 bus (in kernel it is /dev/i2c-3)

    when i tried to run the following command -

    #i2cdetect -r -y 3

    Am getting message like -
