Could you attached the extract_proc.dts

https://mvp.my1.ru/extract_proc.rar

The port@2 and port@3 should be port@0 and port@1 for the channel@1

channel@1 {
				phandle = <0x11a>;
				reg = <0x1>;
				linux,phandle = <0x11a>;

				ports {
					#address-cells = <0x1>;
					#size-cells = <0x0>;

					port@3 {
						phandle = <0x11d>;
						reg = <0x1>;
						linux,phandle = <0x11d>;

						endpoint@3 {
							remote-endpoint = <0x115>;
							phandle = <0x11e>;
							linux,phandle = <0x11e>;
						};
					};

					port@2 {
						phandle = <0x11b>;
						reg = <0x0>;
						linux,phandle = <0x11b>;

						endpoint@2 {
							port-index = <0x5>;
							remote-endpoint = <0x11f>;
							bus-width = <0x2>;
							phandle = <0x11c>;
							linux,phandle = <0x11c>;
						};
					};
				};
			};
26

I changed port@2 and port@3 to port@0 and port@1.
Problem still exists.

I took port@2 and port@3 from
kernel_src\hardware\nvidia\platform\t210\porg\kernel-dts\porg-platforms\tegra210-camera-rbpcv2-dual-imx219.dtsi

csi_chan1: channel@1 {
				reg = <1>;
				ports {
					#address-cells = <1>;
					#size-cells = <0>;
					csi_chan1_port0: port@2 {
						reg = <0>;
						rbpcv2_imx219_csi_in1: endpoint@2 {
							port-index = <4>;
							bus-width = <2>;
							remote-endpoint = <&rbpcv2_imx219_out1>;
						};
					};
					csi_chan1_port1: port@3 {
						reg = <1>;
						rbpcv2_imx219_csi_out1: endpoint@3 {
							remote-endpoint = <&rbpcv2_imx219_vi_in1>;
						};
					};
				};
			};

If I swap it

devname = "imx219 30-0010";
proc-device-tree = "/proc/device-tree/host1x/i2c@546c0000/tca9546@70/i2c@0/rbpcv2_imx219_a@10";

with this

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

then I can connect to a second physical camera. This CSI_F and second port of mux i2c.
But in this case sensor-id 1/0 always access to the same device (it’s SECOND physical camera).

And the logs (dmesg | grep imx219) will contain “31-0010” instead of “30-0010”.

Regards!

It worked

module0 {
				badge = "porg_center_RBPCV2";
				position = "center";
				orientation = [31 00];

				drivernode0 {
					pcl_id = "v4l2_sensor";
					devname = "imx219 30-0010";
					proc-device-tree = "/proc/device-tree/host1x/i2c@546c0000/tca9546@70/i2c@0/rbpcv2_imx219_a@10";							
				};

				drivernode1 {
					pcl_id = "v4l2_lens";
					proc-device-tree = "/proc/device-tree/lens_imx219@RBPCV2/";
				};
			};
			
module1 {
				badge = "porg_top_RBPCV2";
				position = "top";
				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 change “front” and “rear” to “center” and “top”.

How these names influence work?
Why don’t work “front” and “rear”?

28

Don’t know why it not working on your case. However tegra210-camera-rbpcv2-dual-imx219.dtsi working without problem for they are defined as “front” and “rear”

Could you modify the badge to check if any different?

29

When I use the code

badge = "porg_front_RBPCV2";
position = "front";
badge = "porg_rear_RBPCV2";
position = "rear";

then the cameras do not work normally. In this case sensor-id 1/0 always access to the same physical device.

I checked the following options:

badge = "porg_center_RBPCV2";
position = "center";
badge = "porg_top_RBPCV2";
position = "top";

badge = "imx219_top_RBPCV2";
position = "top"; 
badge = "imx219_center_RBPCV2";
position = "center";

badge = "imx219_front_RBPCV2";
position = "front"; 
badge = "imx219_rear_RBPCV2";
position = "rear";

It’s working options for two cameras.

30

Could you change the “RBPCV2” to any others strings to try?

31

Sorry for delay.

I researched the third part of “badge”.
This affects the hue of the image.
Next options CH06P1, P5V27C, A6V26, liimx185, 123456 - work with porg_front/rear.

CH06P1 and P5V27C - many purple hue.
RBPCV2 (with imx219_front/rear) - natural color, but there is a little purple hue on the sides.
A6V26 - natural color, but there is a little purple hue throughout the frame
liimx185 - natural color, but one camera is brighter than another.
123456 - low saturation.

I guess there is a more detailed list for the third part of “badge”, is not it?

Regards!

32

Actually the badge information is the tag for loading the ISP configure you can’t apply any of them from the reference board.

33

My problem is same while accessing two cameras one after the other it is capturing images from first connected camera .
Can any one help with this issue
Thank you…

34

Review your device tree in tegra_camera_platform{}, if still have problem please file new topic.

Thanks
