[Aetina] ZED Link Quad v1.4.1 -- cameras not detected after update (AGX Orin, 3× ZED X Mini)

Hardware ZED X
1

Hardware/Software:

  • Jetson AGX Orin, L4T 36.3.0, kernel 5.15.136-tegra
  • 3× ZED X Mini Stereo (GMSL2), ZED Link Quad
  • ZED SDK 5.1.0, stereolabs-zedlink-quad v1.4.1

After upgrading from v1.2.0 to v1.4.1, no cameras are detected by ZED_Diagnostic. On v1.2.0 the cameras were working but timestamps drifted over time, I upgraded hoping to fix synchronization.

Camera serial numbers are visible in the kernel log, so the GMSL links and I2C devices are found. However, no /dev/video* devices are created and ZED_Diagnostic reports 0 cameras.
I attach the dmesg.txt output and the ZED_Diagnostic_Results.json.

Thanks

previous version 1.3.2*

UPDATE: If I uninstall stereolabs-zedlink-quad and reboot, then reinstall stereolabs-zedlink-quad after boot, the camera probing succeeds.
But then, if I restart the system, the probing during booting phase fails again

Hi @LeoBrizi,

Can you run again the diagnostic tool with this command:

sudo ZED_Diagnostic -c

This will provide the full diagnosis of the system.
Do you have any issues while using the latest 5.2.3 version of the ZED SDK?

Hi @mattrouss,

ZED_Diagnostic_Results_no_reboot.json : booting with no driver installed, then installing the driver.

ZED_Diagnostic_Results.json : booting with the driver already installed.

I did not try to use the SDK 5.2.3, but it seems to be a problem of the driver, not the SDK.

Thanks

Update to ZED SDK 5.2.3 and ZED link 1.4.1

ZED_Diagnostic_Results.json (51.5 KB)

After the update, the trick of before is not working anymore. I cannot detect cameras even reinstalling the ZED link driver

Hi @LeoBrizi, thank you for sharing the files, we have taken a look.

Which AGX Orin board are you currently using? Is it an AGX Orin Developer Kit 32Gb from NVIDIA? Or from another vendor?

Hi @mattrouss, you’ve been like Socrates, your questions have sparked doubts in me that help my knowledge grow.
I discovered that the kit I’m using is from the Aetina vendor. After updating everything, I replaced the overlay with a custom one, and now the cameras are detected and operating properly.

P.S. Should I update the topic title to make it easier for others with the Aetina devkit to find?

Hi @LeoBrizi, great to hear that this solved it :grin:

If you can change the title with a mention to the Aetina board that would be great.

Could you also please share for others to find:

  • the Aetina AGX board model you are using
  • the ZED SDK version you are using that is functional
  • the Aetina ZED X driver version you are using that is functional

I cannot change the title of the topic.
I cannot share the AGX board model and the overlay file.
The ZED SDK version is 5.2.3 and the ZED X driver version is the 1.4.1.

If you cannot share the name of the board publicly, you can share it via email at support@stereolabs.com. We would just like to validate whether the board is part of our officially supported systems, and make sure that this issue does not happen again for other customers.

I can take care of changing the topic title :+1:
