Hello All,

What is the port-index mapping of CSI in Xavier NX that can be used in device tree?

CSI 0 <–> CSI A <–> port-index= 0
CSI 1 <–> CSI B <–> port-index= 1
CSI 2 <–> CSI C <–> port-index= 2
CSI 3 <–> CSI D <–> port-index= 3
CSI 4 <–> CSI E,F <–> port-index= 4
DSI <–> CSI G <–> port-index= 6

Are the above mappings correct?

Can I use below configuration to set up 4 cameras on Xavier NX

CSI A,B → port-index = 0, bus-width = 2
CSI C,D → port-index = 2, bus-width = 4
CSI E → port-index = 4, bus-width = 4
CSI G → port-index = 6, bus-width = 2

When I tested 4 cameras with this configuration, the camera on CSI G does not stream.

Thanks

Try modify the port-index in the vi and sensor scope to 5.

		vi@15c10000 {
				port@5 {
 					reg = <5>;
 					e3333_vi_in5: endpoint {
 						port-index = <5>;
 						bus-width = <2>;
 						remote-endpoint = <&e3333_csi_out5>;
 					};
 				};

			i2c@5 {
 				ov5693_g@36 {
...
...
...
...
                                                port@0 {
 							reg = <0>;
 							e3333_ov5693_out5: endpoint {
 								port-index = <5>;
 								bus-width = <2>;
 								remote-endpoint = <&e3333_csi_in5>;
