i followed the instruction on how to Setup the camera module to use the V4L2 block using the link below.

http://www.mathworks.com/help/supportpkg/raspberrypi/ug/add-support-for-raspberry-pi-camera-board.html

Running the Image Inversion Example, I get this:

_The call to realtime_make_rtw_hook, during the after_make hook generated the following error: Error executing SSH command: make: Entering directory '/home/pi/raspberrypi_inversion_rtt' make: * No rule to make target 'build'. Stop. make: Leaving directory '/home/pi/raspberrypi_inversion_rtt'

The build process will terminate as a result.

Error executing SSH command: make: Entering directory '/home/pi/raspberrypi_inversion_rtt' make: * No rule to make target 'build'. Stop. make: Leaving directory '/home/pi/raspberrypi_inversion_rtt' Component: Simulink | Category: Model error_

What went wrong?
