ZED X One S - GMSL driver error & CAMERA STREAM FAILED TO START (Jetson Orin Nano)

Hardware ZED X
1

Hello Stereolabs Support Team,

I am experiencing a streaming issue with my ZED setup and would appreciate your assistance.

Hardware setup:

  • Jetson Orin Nano Development Kit

  • ZED Link Capture Card Duo

  • GMSL2 1–4 M-F cable

  • 2x ZED X One S cameras

Behavior observed:

  • In ZED Explorer, both cameras are detected successfully.

  • I can see live frames from both cameras.

  • However, when running ZED Diagnostics, I receive the following error under the GMSL DRIVER section:

“No camera stream
Unable to establish a proper stream. Please reboot the device. If the problem persists, contact Stereolabs support.”

  • Occasionally after rebooting the Jetson device, the GMSL DRIVER shows a green check mark (✓), but i still having error on the cpp tutorial.

[ZED][ERROR] CAMERA STREAM FAILED TO START in sl::ERROR_CODE sl::camera::open(sl::InitParameters)

Troubleshooting steps already attempted:

  • Rebooted the Jetson multiple times.

  • Switched between the GMSL2 ports.

  • Tested both cameras individually.

  • Issue persists.

It is confusing because ZED Explorer is able to display frames, yet the SDK fails to start the camera stream in C++ examples.
note that i installed the GMSL2 Driver for my jetson orin JP 6.2.

I am attaching the ZED Diagnostic JSON file for your review.

Thank you very much for your support.

Best regards,
Niv

Update:

Hello again,

I would like to provide an update regarding the issue.

I have uploaded a new ZED Diagnostic JSON file. The diagnostic tool now passes all the requirements, and no errors are reported in the GMSL DRIVER section.

However, the C++ tutorial still fails with the same error:

[ZED][ERROR] CAMERA STREAM FAILED TO START in sl::ERROR_CODE sl::open(sl::InitParameters)

After reviewing the system information, I noticed a potential version mismatch:

  • My L4T version: 36.4.7

  • Installed GMSL driver version: L4T 36.4

I suspect the issue might be related to this version difference.

Could you please confirm whether L4T 36.4.7 is fully compatible with the L4T 36.4 GMSL driver?
If not, should I downgrade or install a specific driver version?

Thank you again for your support.

Best regards,
Niv

Hi @NivC
The diagnostic report is not complete.

Please run the commands with sudo:
sudo ZED_Diagnostic -c
sudo ZED_Diagnostic --dmesg

Send the two generated files.

I will do it on Sunday when I get back to office, but from the update of my message you can see the the versions, do you know if it should be compatible?

L4T v36.4.7 is supported.

If you recently updated the Jetson using the command sudo apt upgrade you could need to reinstall the driver.

If you get errors while installing the driver, please refer to this troubleshooting guide:

Note: the guide refers to the ZED Box device, but it’s valid for generic Jetson devkits too.
