The qvio is not showing any data.

qvio was working before, but now we got the error. All ```voxl-camera-server```, ```voxl-px4-imu-server```  and ```voxl-qvio-server`` are  running.

The output of ```systemctl status *``` looks alright:

But, I found the ```imu_server``` error in ```systemctl status voxl-px4```

I did ```systemctl restart voxl-px4``` that fixed the problem with ```px4``` as well.

After this,

And I tried to see the ```qvio``` data again, but it still throws the ```imu``` error.

I had also done the ```voxl-configure-mpa``` before. How can I fix this?

@bgaudel when I configure the ```voxl-configure-qvio```, I didn't get ```voxl-configure-qvio factory_enable_imu_px4``` option.

@bgaudel Did you ever get this resolved.  I'm experiencing the same thing with IMU_MISSING STALLED

@sansoy Even though it's missing from the bash autocomplete options, what happens if you run `voxl-configure-qvio factory_enable_imu_px4`

@tom ![Screenshot from 2024-02-14 15-48-11.png](https://forum.modalai.com/assets/uploads/files/1707950928552-screenshot-from-2024-02-14-15-48-11.png) i did that and tried restarting the voxl-qvio-server but it wont start.

@tom i ran 
journalctl -u voxl-qvio-server
and saw this message as the extrinsics.conf file doesnot exist

failed to find extrinsics from imu_px4 to tracking in /etc/modalai/extrinsics.conf

@sansoy Okay you're switching between rb5 and voxl2, the approaches are different for each.

The easiest way for either is to run `voxl-configure-sku -w` and go through the wizard, then running `voxl-configure-mpa`

## Reply by sansoy · 2024-02-15 03:47:08 UTC (in reply to tom)

@tom thanks tom!
   
with voxl-configure-sku -w 
I assumed the option to select is
6) px4-autonomy-dev-kit

i then ran voxl-configure-mpa
saw a few errors but the qvio is working now with no errors.
