I have been having some serious issues with compiling GRIP on the Raspberry Pi. I would like to be able for the Raspberry Pi to handle the camera feed and the processing locally on the Raspberry Pi. Also the camera data sent from the Raspberry Pi to the RoboRIO.
Check out this wiki page. If you run into any problems, consider looking into this issue thread or asking on the gitter
Why do you want to send camera data from the raspberry pi to the roboRIO?
