IMU sensor is not working on Raspberry pi

[Turing47]

Hi, I am using Realsensor D455 with a raspberry Pi 4B. I also use it with my desktop. The sensor works well on desktop. But with Raspberry Pi. I cannot get IMU measurement, even monocular image occasionally. I also use ROS, and it has the same problems.

Here is a screen shot:

Do you have any idea?

Hi @Turing47 There are known problems with using the IMU on Raspberry Pi. Examples of such reports are #7391 and #10395

[Turing47]

Hi, @MartyG-RealSense the sensor cannot get any data with IMU even I only run the motion module in real sense viewer. I think my problem is different with those.

[MartyG-RealSense]

Even with IMU on its own on Pi there have been problems, whilst depth and color streams have functioned normally. A RealSense team member speculated at #4979 (comment) that it may be a kernel related issue.

Thanks for your explanation. I will pay attention and wait new updates. @MartyG-RealSense

[MartyG-RealSense]

I have highlighted your case to my Intel RealSense colleagues as part of the past pattern of IMU issues on Pi.

[Turing47]

@MartyG-RealSense Thank you very much. I will try this on Ubuntu 22 in Raspberry Pi.

[MartyG-RealSense]

Hi @Turing47 Do you have an update about this case that you can provide, please? Thanks!

[Turing47]

@MartyG-RealSense No, I have no progress now. Thank you.

[MartyG-RealSense]

Thanks for the update. My Intel RealSense colleagues recommended changing to a different computing board than Raspberry Pi if possible.

[Turing47]

@MartyG-RealSense Thank you. Probably I will use Jetson nano or NUC.

[MartyG-RealSense]

Hi @Turing47 Do you require further assistance with this case, please? Thanks!

[Turing47]

@MartyG-RealSense Do you have any other methods? I do not how to solve the problem, so I started to work on something else. If you have any suggestions I am happy to give it a try.

[MartyG-RealSense]

Hi @Turing47 I do not have any alternative suggestions to the advice from my colleagues to use a computer / computing device other than Raspberry Pi, unfortunately. I do apologize.

[Turing47]

@MartyG-RealSense No worries. If I get new information, I will share it with you in the future. You can close this topic. Thanks for your suggestions.

Thanks very much, @Turing47 - you are very welcome.
