Dear Stereolabs Team

after updating the IMU sensor fimware we started a new testrun and encountered one more crash, the installation in the museum shuts down after this error occurs:

Is there anymore advise or trick we can do to eliminate this as well?
Is there maybe a way after this to restart a camera, up until now when we tried restarting a camera eveything froze.

Hi @pachermann
Please run the ZED Diagnostic tool and post here the content of the generated diagnostic file.

Thanks for your quick answer, i have to organize this at the museum venue first, then i post it.

thanks

4

Are you using any kind of USB extender?

5

No we are using the original 10 meter from your store.

6

In this case, are you ingesting the additional 5V power using the micro-USB port?
Sometimes this is required if the host PC does not provide enough power to guarantee a stable connection.

7

Our motherboard is connected via usb-a of your 10 meter.

each usb 3.1 bus has its own full bandwith lane.

Would it help if we use the USB Fiber Cables?
we have used this PC with 4 zedcams 2 years agon but with fibe usb.

p.s: is there a way or tool to mesure this on the motherboard?

8

i have now die diagnostic files of both the cameras:

ZED_Diagnostic_Results_CAM1.json (16.3 KB)

ZED_Diagnostic_Results_CAM2.json (16.3 KB)

9

No, normally they are a source of problems because they do not replicate the USB2 channel behaviors required by the MCU module.

They both do not show any clue of problems.

The only thing that I would recommend is to upgrade the system to CUDA 12 and ZED SDK for CUDA 12. It’s not recommended to use CUDA 11 with RTX GPU models.

10

I see, but when we tested the newer systems, nothing worked with DX12, it crashed nonstop.
fusion wasnt even working stable, as soon as we used the unity exe it crashed the whole system and it was the same exe we run now.
Now at least it works most of the time like in 11 days only 3 times this crash happens from the log.

This old SDK and cuda version setup is the only that ever worked well enough.

If we change this system in the museum, we risk never having it working again.

So you are saying the only source of evil can be the old cuda core version?

11

Can i ask a different question? Is it 100% certain that if for example, we use the fiber version of your setup the fusion is 100% better and stable?

We are using this now: but we do not have a server but a gaming PC

This is something different. I suspect it’s not related to ZED SDK problems.

This is only a recommendation.

With “server” we mean a powerful PC that can handle the data fusion. A gaming PC is a good server indeed.
