I'm following along with the Voxl 2 Hardware Setup documentation and have an issue with the imu server not starting. I can issue the voxl-imu-server imu0 command and the output looks fine with the exception that it starts with 

```
"Unit imu_app.service could not be found"
```

When issuing the voxl-inspect-imu imu0 command, the output is

```
"waiting for server at /run/mpa/imu0/"
```

If I go to the path /run/mpa/, the only contents are hires, imu_apps, stereo, and tracking.

My voxl-version output is as follows...

```
--------------------------------------------------------------------------------
system-image: 1.2.1-M0054-14.1a-perf
kernel:       #1 SMP PREEMPT Mon Apr 18 20:36:27 UTC 2022 4.19.125
--------------------------------------------------------------------------------
hw version:   M0054
--------------------------------------------------------------------------------
voxl-suite:   0.7.0
--------------------------------------------------------------------------------
```

and my voxl-inspect-services output is as follows...

 ```

Any help would be appreciated!

It is probably worth upgrading the software to the latest release. The version you have is really old. I guess I can't say for sure that it will fix the problem, but it's likely to match the docs better for getting going :-)
