ZED Link Capture Card Duo — Only One GMSL2 Group Streaming on Orin NX

Hardware
1

Hello, I recently purchased a ZED Link Capture Card Duo and 4x ZED X One GS cameras, which I’m attempting to run on a Jetson Orin NX box. I followed the documentation from the following pages:

Hardware connections

  • Capture card connected to the Jetson CSI ports via 2x 22-15 pin CSI cables

  • External 12V 2A power supply connected to the capture card

  • 4 cameras connected via the 4-to-1 GMSL2 cable included with the card

  • Based on the documentation, CAM01 port is connected to the center port of the capture card

Problem

Only 2 out of 4 cameras are streaming, and both belong to the same GMSL2 group. The second GMSL2 group appears to be completely inactive. According to the documentation and previous emails exchanged with support before purchasing, the capture card duo should be able to accommodate 4 ZED X One GS cameras (“up to 2 per group → https://www.stereolabs.com/docs/embedded/zed-link/dual-jetson-orin-nano-devkit-setup).

I have attached a wiring image and a diagnostics log for reference.

Note

I’m aware the documentation states the ZED Link Capture Card is not officially supported on Orin NX due to the passive cooler and warranty concerns. We have already voided the warranty and decided to make light modifications to the casing to accommodate the two CSI cables because purchasing a new ZED Box was not a viable option for us.

Any help or pointers would be greatly appreciated!

Hi @VanjaLjubobratovic
Welcome to the Stereolabs community.

What kind of Orin NX box? Who’s the manufacturer? Model?

What do you mean here? Please add details.

“Dpkg list Stereolabs”: [
“ii stereolabs-zedlink-duo 1.4.0-LI-MAX96712-L4T36.4.0 arm64 NVIDIA Kernel DTB Modified Package by Stereolabs”

Please note that you must not use the ZED Link Duo driver with the ZED Box, but the drivers for the ZED Box itself, otherwise you will break functionalities.

Hi, so to answer your questions:

It’s a ZED Box Orin NX 8GB that came without the pre-installed GMSL2 capture card (Auvidea JNX42 carrier board).

See the quote below found in the docs → ZED Link capture cards - Stereolabs

:warning: Warning :warning:

It is not possible to disassemble a ZED Box Orin that was purchased without a pre-installed GMSL2 capture card with the intention of installing it later.

The ZED Box Orin features a passive heat dissipation system that could be damaged if the device is disassembled, potentially causing failures and serious damage to the NVIDIA® Jetson™ module. As a result, the warranty will be void if the device is opened.

I’m embarrassed to say it, but this was the solution. I installed incorrect drivers by mistake. After installing drivers for ZED Box Orin NX, the cameras work as expected.
Thank you for your help.
