Simultaneous connection of two Raspberry Pi Camera V2

Thank You!

When I connect to the first or second camera, capture is always from the first camera, i.e., through “/proc/device-tree/host1x/i2c@546c0000/tca9546@70/i2c@0/rbpcv2_imx219_a@10”.

If I physically disconnect the first camera, then the second will be defined as “imx219 31-0010” and “/dev/video0”, i.e., all is OK. But if I connect to this camera there will be an error.

Work always CSI_A port and i2c@0.
What is wrong?

DTS:

tegra-camera-platform {
		compatible = "nvidia, tegra-camera-platform";
		status = "okay";
		num_csi_lanes = <0x4>;
		max_lane_speed = <0x16e360>;
		min_bits_per_pixel = <0xa>;
		vi_peak_byte_per_pixel = <0x2>;

		max_pixel_rate = <0x3a980>;
		isp_peak_byte_per_pixel = <0x5>;

		modules {

			module0 {
				badge = "porg_front_RBPCV2";
				position = "front";
				orientation = [31 00];

				drivernode0 {
					pcl_id = "v4l2_sensor";

					proc-device-tree = "/proc/device-tree/host1x/i2c@546c0000/tca9546@70/i2c@0/rbpcv2_imx219_a@10";

				drivernode1 {

					proc-device-tree = "/proc/device-tree/lens_imx219@RBPCV2/";
				};
			};
			
			module1 {

				position = "rear";
				orientation = [31 00];

				drivernode0 {
					pcl_id = "v4l2_sensor";
					devname = "imx219 31-0010";
					proc-device-tree = "/proc/device-tree/host1x/i2c@546c0000/tca9546@70/i2c@1/rbpcv2_imx219_f@10";
				};

				drivernode1 {
					pcl_id = "v4l2_lens";
					proc-device-tree = "/proc/device-tree/lens_imx219@RBPCV2/";
				};
			};		
		};
	};

I also edited next sections: vi, nvcsi and i2c@546c0000.
I can upload the full DTS file.

Image file - not changed.
If I change Image from Linux_for_Tegra/rootfs/boot the OS isn’t loading.

Regards!
