Sorry, we currently don’t provide an API to do it or other alternatives. I’ll check with the team if something like dfu-tool can be used
@adujardin Possibly bad news: I am currently looking at a Zed 2i with IMU firmware 778 (Zed SDK 5.0.5, Ubuntu 22.04) whose left camera dropped out, returning an all black image. The right camera still works.
I do not know if the image is strictly black vs. very underexposed. I attempted to shine a bright light into the left camera and did not notice any changes in the image.
I have not attempted to reboot or reinitialize the camera or reset the AGC/AEC settings, I am going to leave it in this state in case there is anything you want me to do to get more information about it. Let me know as soon as possible, as somebody is likely to ask me to reset this camera in the next couple of days.
Assuming this is the same issue (as opposed to the left camera simply failing, I do not know yet), the 778 update seems to have greatly decreased the chances of the problem occurring, but has not eliminated it entirely. This is the first failure I’ve seen since June of 2025, over ~10 cameras running continuously.
I can kill -9 our software then try to record an SVO if you can tell me how to do it on the command line in a way that does not reinitialize the camera.
It is possible that the camera has simply failed and this is not the same issue. I will not know until I reboot the camera.
Thanks for the updates
Closing and reopening the camera should fix the issue by resetting the camera internal state. If you can take screenshots of the camera with and without the light that would be helpful if SVO recording is not possible at runtime, thanks.
Then you can try rebooting to see if it’s not a more serious camera failure to make sure

Thanks for the prompt reply.
(Un)fortunately, before I had a chance to grab images, it looks like the camera disconnected and the SDK reset it automatically and it fixed itself…
[ZED][Grab] Detected Connection Failure. Trying to recover the camera with sn 39246086 ...
..[2026-02-01 398480500 UTC][ZED][INFO] [Grab] Camera module reset
In fact, checking the kernel logs, it looks like this camera has been disconnecting somewhat frequently with:
uvcvideo 2-3.4.2:1.1: Non-zero status (-71) in video completion handler.
Which makes me wonder if it’s the same issue I saw with Zed 2i resets every few minutes. Or even some combination of both these issues.
Sorry, I don’t have any more information for now. I’ll try to act faster next time.
