Failed to detect a Camera Board connected to the Raspberry Pi hardware. If you connected a Camera Board, check that:
1. The ribbon cable connecting the camera module to the board is securely seated at both ends
2. The connectors on the ribbon cable are inserted to the CSI connector and the camera PCB the right way
3. Camera Board is enabled in the "raspi-config" Linux utility

There are a few things to check.

1) Did you correctly install Raspberry Pi Support package? This can be found with a command below.

>> matlabshared.supportpkg.getInstalled

2) What does the command below show?

>> rpi = raspi

Does the command show you available camera correctly? Or are there multiple available cameras?

3) Did you correctly check what the error message suggests?

4) Another troubleshooting guide can be found in the doc below.

5) Last but not least, do you use USB camera by any chance? The cameraboard function is supposed to be used with CSI camera and may not support USB camera.
