Camera interfaces for DRA74x Jacinto6

Other Parts Discussed in Thread: TVP5158

I am using TI JACINTO 6 with JAMR3 application board. here am using GLSDK .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.

    Hi,

    It appears that the I2C interaction with the TVP decoder is failing. We typically see the probe failure errors when there is no JAMR3 board connected. Can you please check that the daughter board is connected correctly?

    Thanks for your reply Venkat.

    I connected the Daughter board JAMR3 properly.i can see that JAMR3 is getting detected in Boot Message-

    Niranjan,

    I tested tvp5158 capture on my board with the following command. I am using
    Processsor SDK Linux Automotive 3.01, which is the successor to GLSDK.

    # dmabuftest -s 32:1280x800 -d /dev/video1 -c 720x240@YUYV

    As I said in my first response, your problem is likely more to do with
    software than hardware. Please check the switch settings and the connection of
    the JAMR3 board to the DRA7xx EVM. If the hardware is connected correctly,
    you should not see the probe failure messages like below for tvp5158.

    [ 6.406210] tvp5158 1-0058: Unable to of_probe
    [ 6.411333] i2c 1-0058: Driver tvp5158 requests probe deferral

    These are the switch settings I am using on my EVM.

    SW2 depends on the boot mode you are using

    SW3[7:0] 1000 0001

    SW5[9:0] 00 0001 0100

    SW8[1:0] 11

    On JAMR2

    SW2[1-2] = [OFF, ON]

    OFF is towards the interior of the board, ON is towards the edge of the board.

    Please check the switch settings and hardware connections once again.

    regards,
    Venkat

    Niranjan,

    TVP5158 is enabled by default in GLSDK kernel configuration. You can look at
    the file "board_support/linux/ti_config_fragments/audio_display.cfg" to confirm this.

    audio_display.cfg
    45: CONFIG_VIDEO_TVP5158=y

    You can also check for the same by running

    # zcat /proc/config.gz | grep -i tvp

    on the target.

    Can you please confirm that this is the case on your system with the default
    GLSDK 7.04 kernel? Please also build the kernel with the default GLSDK
    configuration via "make linux" and confirm that it behaves in the same
    fashion.

    Please let me know if the tvp5158 probe using the default GLSDK kernel
    continues to be successful after connecting a camera. If possible, please try
    with a DVD player instead of the camera (or) please ensure that the camera is
    functional via other means.


    On a side note, I would recommend moving the latest SDK for the DRA7xx EVM.
    This will not help with your current issue but it will be easier for us to
    provide support for future issues.

    but in GLSDK 7.04 with kernel 3.14 i can find kernel configuration... where i can download kernel configuration (4.4)..?please provide me the Link.and the steps you followed..

    GLSDK 7.04  - Here am using rear view camera with RCA Connector.i connected the camera to VIP Port.. but am getting error like-

    [ 6.406210] tvp5158 1-0058: Unable to of_probe

    but I connected the same camera with RCA to USB converter to the board (DRA74x) via USB hub.i tested with simple Opencv code to capture frames from webcam,.here also am getting error like-

    Yes. JAMR3 can be used for capturing analog video using TVP5158. Here is a video showing the exact usecase you are trying to do with GLSDK 7.04.

    www.youtube.com/watch

    The usecase you are trying out is a standard usecase that we test. I am not sure what is wrong. I am waiting for our VIP expert to be back from leave so that he can provide some debug pointers.

    Hi Niranjan,

    I think that the bad address indicates that the device is not present

    Do you see any logs printed by the tvp5158 driver

    Maybe you can run the app with "strace -f"

    Also check if the /dev/video devices are registered for the analog cameras

    You should see somthing like 'tvp5158: NTSC video detected' in the kernel bootlog

    Regards,
