Camera Overlays

The ARK Jetson PAB Carrier has 4× 2-lane CSI ports. Camera configuration is managed through device tree overlays, and the image ships with the IMX219 quad overlay active — IMX219 cameras work on all four ports out of the box.

Supported Cameras

Sensor	Resolution	Overlay	Status
IMX219	3280x2464	Camera IMX219 Quad	Working (default)
IMX477	4056x3040	Camera IMX477 Quad	Working
IMX708	4608x2592	Camera IMX708 Quad	Working

4-lane CSI modes are not supported — 2-lane provides full resolution at 30 fps for the IMX477. See cameras.md in the kernel repo for sensor details, verification commands, and known issues.

Switching Overlays

List the overlays available on your Jetson:

sudo /opt/nvidia/jetson-io/config-by-hardware.py -l

Apply one and reboot:

sudo /opt/nvidia/jetson-io/config-by-hardware.py -n 2="Camera IMX477 Quad"
sudo reboot

Verifying a Camera

Check that the sensor is detected:

nvargus_nvraw --lps

ARK-OS also ships check_cameras.sh (on PATH) which stream-tests every connected CSI camera, and the ARK-UI Video page shows a live stream of the first camera.

Custom Overlays

To build your own camera overlay — or install one on an already-flashed system — follow camera_overlays.md in the kernel repo.
