AM62A7-Q1: PANEL BT656

Part Number: AM62A7-Q1

Tool/software:

We want to check the BT656 output on the PANEL.

I want to use fb output for the basic edgeai-init service.

In that state, I only want to modify VP CONFIG.

devmem2 0x3020B004 w 0x00000361
devmem2 0x3020B000 w 0x01100004

Since the output goes to BGRA, CSC was enabled.

I followed the method above, but there is no response in the PANEL.

What else should I check?

  • Hi Kim,

    Our expert is out of office this week. Expect a response sometime next week when he will back.

    Apologies for the delay.

    Best Regards,

  • Hi,

    We currently do not support BT656 since our EVM only supports RGB output. In the past, I have seen customer enable BT656 with just the two commands you shared

  • Hi

    We are using a camera with input as BT656

    We are using panel-simple to display on OLED.


    The strange thing is that videotestsrc and v4l2src are saved as jpeg respectively and when output
    videotestsrc is displayed normally, but v4l2src is displayed in abnormal colors.

    When using the command below, UYVY data is connected to the sink, but I am curious why the results are different.

    • videotestsrc

      • gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw, format=UYVY, width=640, height=480 ! jpegenc ! filesink location=videoTestSrc.jpg

    • v4l2src

      • gst-launch-1.0 v4l2src device=/dev/video3 num-buffers=1 ! video/x-raw, foramat=UYVY, width=640, height=480 ! jpegenc ! filesink location=cam_cap_2.jpg

    • Display
      • gst-launch-1.0 filesrc location=videoTest.jpg ! jpegdec ! imagefreeze ! videoconvert ! fbdevsink

    Regards,
