Hello @SivaRamaKrishnaNV ,
The camera_sample app does not work for single camera.
The command used:
sudo ./sample_camera --rig test.rig.json --offscreen 2
The RIG File (for interface I have tried combinations in range csi-e and csi-f + links 0..3):

I want to double check if the above commands are working when cameras connected in Red color circled port?

Camera connection

@SivaRamaKrishnaNV , yes, second from the top port

@SivaRamaKrishnaNV ,
As fdiscussed before, I am attaching a photo of camera connection.

@SivaRamaKrishnaNV could you please let me know if you have an update on this?

Could you try with below gmsl parameter in rig.json
camera-name= IMX728_RGGB,interface=csi-ef,CPHY-mode=1,link=0,output-format=processed,async-record=1,file-buffer-size=16777216 and share your observation. Use --offscreen=1 flag with sample_camera to avoid GUI display.

@SivaRamaKrishnaNV
Thanks for the instructions.
Unfortunately, the observations are the same.
I have run the sample_camera application with following RIG File:

{
    "rig": {
        "sensors": [
            {
                "name": "camera:sensor:name",
                "nominalSensor2Rig_FLU": {
                    "quaternion": [

                        1.0
                    ],

                    ]
                },
                "parameter": "camera-name=IMX728_RGGB,interface=csi-ef,CPHY-mode=1,link=0,output-format=processed,async-record=1,file-buffer-size=16777216",

                "protocol": "camera.gmsl"
            }
        ],
        "vehicle": {
            "valid": false
        },
        "vehicleio": []
    },
    "version": 8
}

Run as follows: ./sample_camera --rig /tmp/rig.json --offscreen 1
