Hi, 

When I am running command ```voxl-vixion-px4 -d```, I am getting an error saying "ERROR validating VIO data received through pipe: read partial packet".
Can you tell me how to resolve this error. Output is shown below.
```

Hi @Anubhav ,

Can you please run `voxl-version` for us and paste here?  Are you building code yourself or running the standard VOXL SDK?

Thanks!

Hi @modaltb,

The output of voxl-version is shown below. 
```
voxl:~$ voxl-version 
--------------------------------------------------------------------------------
system-image: 3.8.0
kernel:       #1 SMP PREEMPT Tue Apr 26 18:08:39 UTC 2022 3.18.71-perf
--------------------------------------------------------------------------------
hw version:   VOXL
--------------------------------------------------------------------------------
voxl-suite:   0.8.1
0.7.0
--------------------------------------------------------------------------------

```
No, I am not building code myself, and running standard VOXL SDK. I have flashed new image of voxl because I was getting issue posted [here](https://forum.modalai.com/topic/1235/voxl-cam-is-not-connecting-to-qgc-through-udp). And the reason for choosing 3.8 system image was because of voxl-mavlink-server which is present in voxl-suite v0.7 and v0.8 and both requires voxl system image 3.8+.

Thanks!
