Hi,

We noticed that on our VOXL, voxl-vision-px4 isn't running.

When we try to configure mpa, the following error is raised:

Also, in /data, there is no folder named /modalai.

How can we fix this?

Thanks in advance!

Hi, 

What version of the software stack is your drone running? Can you post the output of ```voxl-version``` and ```voxl-inspect-services```.  Also, can you paste the full log from VVPX4 with ```journalctl -u voxl-vision-px4```. Finally, did you recently reflash the drone? All of our drones shipped within the last year and a half or so should have a factory mode saved in that data directory, which shouldn't get overwritten unless you're reflashing the drone (and choose to wipe it since we can reflash without wiping the data partition).

Hi @Alex-Gardner,

We recently flashed the voxl to 3.8.0. When we noticed voxl-vision-px4 we reflashed it again with and without wipe, to see if that would resolve it.

**Outputs:**
**voxl-version**
