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

Could you try adding deserializer=MAX96712_Fusa_nv,disable-custintf=1,output-format=raw+processed,format=mp4,to GMSL params.

33

@SivaRamaKrishnaNV ,

I have tried to run sample_camerawith two parameter lines ( just in case:) ):
1. The one you have suggested:
camera-name=IMX728_RGGB,interface=csi-ef,CPHY-mode=1,link=0,async-record=1,file-buffer-size=16777216,deserializer=MAX96712_Fusa_nv,disable-custintf=1,output-format=raw+processed,format=mp4
The error status is: Driveworks exception thrown: DW_INVALID_ARGUMENT: Invalid camera vendor type
The log: log_1.txt
2. Added deserializer line to parameters that worked previously for us on other platform:
camera-name=IMX728_RGGB,interface=csi-ef,link=0,isp-mode=yuv420-uint8,file-buffer-size=16777216,skip-eeprom=1,fifo-size=4,deserializer=MAX96712_Fusa_nv,disable-custintf=1,output-format=raw+processed,format=mp4
The error status is: Driveworks exception thrown: DW_UNEXPECTED_EVENT: CameraMaster::resume failed with sipl status 10
The log: log_2.txt

log_1.txt (82.2 KB)

log_2.txt (98.0 KB)

34

Could you add skip-eeprom=1, nito-file=</path/to/NITOFile> and see if it bypasses the error?

Is it with same camera module?

Could you also share nvsipl_query_sample output on target. Also, Which coax color you have on the port to connect camera?
From the shared nvsipl_camera commands, it looks like link=2,3 has cameras.

35

@SivaRamaKrishnaNV , thanks for your message.
I will post results as soon as I have a chance to perform the tests you suggested.

36

Hello @SivaRamaKrishnaNV ,
thanks for pointing out the incorrect link values. Luckily I was trying values in range 0-3 each time. :)

Is it with same camera module?
Yes, but those parameters are tested and are working on Orin.

I have added the suggested parameters and run tests:

“parameter”: “camera-name=IMX728_RGGB,interface=csi-ef,CPHY-mode=1,link=2,async-record=1,file-buffer-size=16777216,deserializer=MAX96712_Fusa_nv,disable-custintf=1,output-format=raw+processed,format=mp4,skip-eeprom=1, nito-file=/usr/share/camera/IMX728_RGGB.nito”,

In both cases sample_camera logs indicate errors and application becomes irresponsive:

Link 0 and 1 yeld the same results as before.

NOTIF_ERROR_DESERIALIZER_FAILURE indicates issue with deserializer. Does nvsipl_camera working when you got this error? Can you poweroff/poweron the target and see if issue is observed.

38

@SivaRamaKrishnaNV , sorry for the late reply.
I’ll provide details once I am able to rerun the tests.

39

@SivaRamaKrishnaNV ,
I have rerun the tests. nvsipl_camera is working.
Powering machine off and on does help.

Please, note that I cannot terminate the sample_camera after running it with configuration from previous post. It stays running and does not close unless I reboot the target.

40

So sample_camera is working with your camera module after Powering machine off and on ?

Are you using CTRL+C to terminate application? After smooth closure of application you should see message like below

[26-01-2026 09:48:46] DriveworksGL SDK released
[DW][INFO] Release Successfully.
41

Sorry for confusion, I made a typo. Powering the Target off and on did not help :(
Ctrl+C does not work in that case.

There is one additional thing. In case it can help somehow to find the cause with the issues with DW API for Sony cameras.
Our team was provided with instructions to run nvsipl_camera on other ports.
Currently we have it running on Ports #1, #2 and #4 with following parameters:

  • sudo ./nvsipl_camera -c "IMX728_96724_RGGB_CPHY_x4" -m "0x1100 0x0000 0x0000 0x0000" --showfps --disableISP2Output --disableISP1Output
  • sudo ./nvsipl_camera -c "IMX728_96724_RGGB_CPHY_x4" -m "0x00100 0x0000 0x0000 0x1100" --showfps --disableISP2Output --disableISP1Output
  • sudo ./nvsipl_camera -c "IMX728_RGGB_CPHY_x4" -m "0x0000 0x0000 0x1100 0x0000" --showfps --disableISP2Output --disableISP1Output

I have tried to run the camera_sample on other ports with interface=csi-ab,link=2and interface=csi-gh,link=2. But no luck. However, the issue with Ctrl+C not working is also not present on ports 1 and 4.

42

So,

  1. first command is for camera connected in port 4 link 2,3.
  2. Second command seems to have some typo, looks like two camera connected in port 1(link 2,3) and 1 camera connected on port 4(link 1?)
  3. Third command is for 2 camera connected at port 2(link 2,3)

All the above commands working without any issue?

To debug the issue on DW, Lets stick to use single camera on port 2 with camera connected at link 2.

When you use above params you seems to notice CameraSynchronous::getNextFrame: Failed to read frame from camera with status : DW_NOT_READY error . Is this noticed in fresh run after reboot?

Please clear the /var/log/syslog before running sample_Camera and set env variaible export DW_SIPL_NVMEDIA_VERBOSITY=4 and share /var/log/syslog and sample_camera log for further debugging.

43

Sorry for the late reply.
Yes, everything you have written is correct.

Is this noticed in fresh run after reboot?
Yes, it is present after reboot :(

I unfortunately do not have a posibility to rerun the test. Will provide details as soon as I have the results.

45

Could you please provide any update for this topic?
