I tested these sensors with VOXL Flight.

hires: Starvis IMX412
tracking: OV7251 167° Tracking Sensor Module
ToF

The error occured after I typed ```voxl-configure-cameras 6``` and check hires view in voxl-portal.

And I also tested it with System Image 4.0, but the error also occured.

```

I found "ERROR:   Recieved Fatal error from camera:hires" from the message.
so I disabled hires with voxl-camera-server.conf.
And ToF and Tracking work.
Would this require replacing the Starvis camera?
Or do I need to set up something else?

this usually means one of the following:

* camera configuration does not match what is installed. the configuration needs to match what is installed, not what you want to use
* a connector is not properly seated
* a connector is backwards
