Hi,

Unfortunately we can't get QVIO to work, voxl-inspect-qvio gives 0 position values and jumps between OKAY and FAIL.
Additionally, after we reset the drone by flashing the factory image we no longer see the "Pointclouds" tab in the portal. How do we enable this again?
I would appreciate any tips on how to solve this.

It is likely you need to configure the system after reflash. See [voxl-configure-mpa](https://docs.modalai.com/voxl-configure-mpa/)

Thanks for the hint, qvio is now showing correct positions.
However, pointcloud is still not available in the portal, how to enable that again?

The pointcloud functionality in voxl-portal is only available through the dev repo right now. To upgrade your current installation, you can run:
```bash
voxl-configure-opkg dev
```
to point opkg towards our dev repository, and upgrade using:
```bash
opkg upgrade voxl-portal
```

Thanks,

I had to upgrade other packages as well due to dependency constraints. I wasn't able to resolve all of them cleanly because it looks like opencv and voxl-opencv are both required by different packages.

Unfortunately now the flight control interface seems to be broken, reporting:

```

But at least pointclouds are showing now.

Additionally, I am unable to view the pointcloud in RViz :/
It connects and can show images but not spatial data:

```
No tf data.  Actual error: Fixed Frame [map] does not exist
```

Maybe there is a misconfiguration of ros on the seeker?
