Using IMX219 CSI Cameras#

Work in progress

Todo

Add further testing steps, results, and images.

Camera connection#

You have to make sure the CSI camera FPC cable is connected in proper orientation for camera to work properly. The image below shows how it should look when connected correctly.

Tip

The image shows camera connection to CSI0 port, you can similarly connect a camera to CSI1/DSI0 port

Configuring CSI camera#

To enable an IMX219 CSI camera, we have to modify the following file: /boot/firmware/extlinux/extlinux.conf. We can check the available list of Device Tree Overlays using command below,

ls /boot/firmware/overlays/ | grep "beagley"

When executed the above command should give output show below,

debian@BeagleBone:~$ ls /boot/firmware/overlays/ | grep "beagley"
k3-am67a-beagley-ai-csi0-imx219.dtbo
k3-am67a-beagley-ai-csi0-ov5640.dtbo
k3-am67a-beagley-ai-csi1-imx219.dtbo
k3-am67a-beagley-ai-dsi-rpi-7inch-panel.dtbo
k3-am67a-beagley-ai-lincolntech-185lcd-panel.dtbo

Using CSI Port 0#

Add the line shown below to /boot/firmware/extlinux/extlinux.conf file to load the IMX219 CSI0 device tree overlay:

fdtoverlays /overlays/k3-am67a-beagley-ai-csi0-imx219.dtbo

Your /boot/firmware/extlinux/extlinux.conf file should look something like this:

label microSD (default)
   kernel /Image
   append console=ttyS2,115200n8 root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait net.ifnames=0
   fdtdir /
   fdt /ti/k3-am67a-beagley-ai.dtb
   fdtoverlays /overlays/k3-am67a-beagley-ai-csi0-imx219.dtbo
   initrd /initrd.img

Now reboot you BeagleY-AI to load the overlay,

sudo reboot

After reboot you can use beagle-camera-setup to setup your IMX219 CSI camera,

sudo beagle-camera-setup

beagle-camera-setup should give you below output,

debian@beagle:~$ sudo beagle-camera-setup
[sudo] password for beagle:
IMX219 Camera 0 detected
   device = /dev/video-imx219-cam0
   name = imx219
   format = [fmt:SRGGB8_1X8/1920x1080]
   subdev_id = /dev/v4l-imx219-subdev0
   isp_required = yes

To check if the configuration is successfull you can check the video devices with ls /dev/ | grep video and you should see video-imx219-cam0 listed as show below,

beagle@beagle:~$ ls /dev/ | grep video
video-imx219-cam0
video0
video1
video2
video3
video4
video5
video6
video7
video8
