Zed Mini: IMU not working. Firmware shows -1

Hello,

My Zed Mini does not output IMU data. In the ZED Sensor Viewer it shows this: (Accelerometer and Gyroscope show no values either

Checking the Zed Explorer the IMU firmware shows -1. I tried updating the firmware:

4

But this never gets pas the “waiting for device to reboot”

After the following message it just crashes:

3

The depth viewer works fine by the way, this is only the IMU.

Hi @asneab2,

Could you run the ZED_Diagnostic tool and send the resulting JSON file so that we can investigate the issue?

Hi

i tried running the diagnostic tool but it keeps crashing. Here’s a gif with a bit of the loading part cut out

My cuda version is 12.6

Hi @asneab2,

Have you tried flipping the USB cable on the ZED Mini, or changing the USB 3 port on your PC and has this made a difference? This allows us to tell if there is a USB issue.

Yes the camera only works in 1 USB direction. If I flip the USB, it does not connect at all.

I tried multiple USB ports, one of them had the diagnostic tool reach 78% instead of 20% but then still crashed. The IMU firmware still showed -1.

Hi @asneab2,

Can you try resetting the IMU configuration of the camera?
To do this, you can open a Windows shell and go to the ZED installation folder.
At this point, you can call the “ZED Diagnostic --calib_imu” command to reset your camera’s IMU calibration.

Hi @mattrouss

I ran the calibration. it seemed to run for a while, but in the end it resulted in Calibration Err Code: 0x006 && 0x006:

The firmware in the Zed Explorer still shows -1, and the Zed Sensor Viewer still does not show any values.

Hi,

Is it possible for you to download a tool called “Usb Device Tree viewer” (USB Device Tree Viewer) and send us the report ?
You can share the report privately at support@stereolabs.com

This will give us a lot of information.

Thanks!

I have sent the report to the mail address. Thanks in advance!
