@jonathankampia ,
Have you checked that your Boson actually works (using a USB interface with either Flir GUI or a UVC interface)?
Also, is your Boson configured to send MIPI data in 8-bit raw format?
The camera server cannot change the FPS of Boson (or any of its streaming parameters). In fact there is no communication at all happening from VOXL2 to Boson (besides just probing / detection) - all the settings have to be configured by the user prior connecting to VOXL2 (including resolution, fps, etc).

Please double check these points..
