Hello @Alex-Kushleyev @Eric-Katzfey 
I had build voxl-qvio-server and flashed the VOXL2 board. while running the voxl-qvio-server the server is broken.
I had refered this link ```https://forum.modalai.com/topic/2551/add-mask-file-to-qvio-algorithm```

Can you help me out figure this out?

@Jetson-Nano There's likely a version mismatch going on, make sure you're building off of the tag of the SDK in which you have loaded on your VOXL2

If you post the output of `voxl-version` I can point you in the right direction

Most likely need to update `voxl-mpa-tools` to latest : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/lib/voxl_common_config.c?ref_type=heads#L655 or use `voxl-mpa-tools` and `voxl-qvio-server` from the same SDK release

@Alex-Kushleyev @tom 
thank you guys for reverting back.
I currently facing another issue with ```voxl-qvio-server```.
The tracking camera is working. The qvio-server is also running,but the cam-stalled message is shown and ```voxl-qvio-server``` is not working.
I have attached the screenshots of the terminals and portal.

@Jetson-Nano What does `/etc/modalai/voxl-qvio-server.conf` look like?

As well as `voxl-inspect-cam -a`

@tom  thank you for reverting , I sorted out the issue, the file name in the voxl-qvio-server was ```opencv_tracking_front_intrinsics.yml``` instead of ```opencv_tracking_intrinsics.yml```
and in the ```voxl-vision-hub``` the name was tracking_front which i renamed in tracking. After the above mentioned changed the ```voxl-qvio-server``` is working fine.
thank you for the support.
