No Camera Stream Error for New ZED X One S Cameras

tldr: new ZED X ONE S cameras does not work, ZED_Explorer -a displays cameras but ZED_Diagnostic shows “No camera stream“ error.

Hardware Setup: ZED Box Mini + ZED X One S Cameras; we confirmed that all the cables/the ZED Box Mini is working since we have other ZED X One S Cameras that work under this setup.

Issue: The cameras are now stuck on “Opening…” when trying to use Zed_Explorer or the Zed Python SDK. When we switch out the cameras with two prior ZED X One S’s that we had, we do not get the issue, suggesting that there is also a problem with the new cameras. Specifically, we seem to be getting a problem with their being “no calibration file” for the new cameras. ZED_Explorer -a shows the new cameras correctly.

As suggested by https://support.stereolabs.com/hc/en-us/articles/360010101213-What-do-I-do-if-my-ZED-ZED-Mini-ZED2-ZED2i-is-not-working, we used the working Zed Box to run diagnostics for the two Zed X One S cameras that are not working, and the two diagnostic output json files are at https://drive.google.com/file/d/1UibHayFuq7HAgtmEgT-MxyLJGg4H6Jzz/view?usp=sharing and https://drive.google.com/file/d/196c_HSXEgVrMHNgEtePGnHlnkEi6biE7/view?usp=sharing .

We tried rebooting, double checked cable connection, made sure we plug in the cameras first and then power on the ZED Box Mini, but the problem persists.

Thus we would really appreciate any assistance.

Hi @ZekaiWang04
Welcome to the StereoLabs community.

To assist you better, we need additional information regarding your device’s condition and system setup.

Please open a terminal console (Ctrl+Alt+t) and run these commands:

  • sudo ZED_Diagnostic --dmesg
  • sudo ZED_Diagnostic -c

After executing the commands, kindly send me the files dmesg.log and ZED_Diagnostic_Results.json located in the folder where the commands were run.

Please also try to run the “Hello ZED” tutorial and send here the output log:

Thanks for your reply! The output logs for sudo ZED_Diagnostic –dmesg and sudo ZED_Diagnostic -c for the two cameras are at 0408 - Google Drive . When running the cpp version of tutorial 1 for we observe the following
