3. Interface & Dimensions​

4. Luckfox Omni3576 Usage Instructions​

Luckfox Omni3576 currently supports the IMX415 camera module. To test the CSI camera, it is recommended to connect the Omni3576 to an HDMI or DSI display. On the Omni3576 baseboard, the CSI (camera) and DSI (display) interfaces share similar physical connectors, so please be careful not to misconnect them. The DSI interface is located near the USB ports. Please refer to the silk screen or hardware schematic to confirm the exact location.

4.1 Hardware Connection​

  • Camera Side: The metal contact surface of the FPC cable should face the back of the camera module, with the blue side facing the lens.
  • Board Side: Insert the cable with the metal side facing down into the CSI interface on the development board and make sure the locking tab is securely fastened.xxx

4.2 Software Testing​

  1. List camera devices using v4l2-ctl:

    v4l2-ctl --list-devices
    root@luckfox:/home/luckfox# v4l2-ctl --list-devices
    rkisp-statistics (platform: rkisp):
            /dev/video17
            /dev/video18

    rkcif (platform:rkcif-mipi-lvds):
            /dev/video0
            /dev/video1
            /dev/video2
            /dev/video3
            /dev/video4
            /dev/video5
            /dev/video6
            /dev/video7
            /dev/video8
            /dev/video9
            /dev/video10
            /dev/media0

    rkisp_mainpath (platform:rkisp-vir0):
            /dev/video11
            /dev/video12
            /dev/video13
            /dev/video14
            /dev/video15
            /dev/video16
            /dev/video19
            /dev/media1

    rkvpss_scale0 (platform:rkvpss-vir0):
            /dev/video21
            /dev/video22
            /dev/video23
            /dev/video24
            /dev/media2

  2. Query camera parameters:

    v4l2-ctl --list-formats-ext --device=/dev/video11

  3. Camera Preview:

    # If running via SSH, ensure the GUI is forwarded to the primary display 
    export DISPLAY=:0.0

    gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! xvimagesink

  4. Take a photo:

    v4l2-ctl -d /dev/video11 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=4 --stream-count=1 --stream-to=/root/cap1.raw --stream-skip=2

5. Usage on Raspberry Pi 4B/5​

  1. Flash the latest official Raspberry Pi OS. Other operating systems are not supported.
  2. Edit the /boot/firmware/config.txt configuration file and add the following line at the end:
    dtoverlay=imx415,clk-37125
  3. Reboot the Raspberry Pi and check whether the driver has loaded correctly:
    dmesg | grep -i imx415
  4. Start camera preview:
    libcamera-vid -t 100000 -o test.h264
