How do I create /dev/video1 for multi camera?


I have two cameras what drivers are both based on ov5693.They are on the same I2C bus in my customer cariier board. They have unique i2c address.They have independent CSI port(CSIb and CSId).

The two cameras work well when it’s single.But now I want them work together.I add their dtsi file in device tree and compile drivers into kernel.Then the two camera’s drivers are probed completed. But there’s only one video0 in /dev.If I hope another driver also create a device node(video1).What should I do?

Best Regards!

Hi there,
You can reference to the …/jetson/kernel-dts/jetson-platforms/tegra210-camera-e3323-a00.dtsi to create two camera sensor use case.
