So I am doing some experimenting with the raspberry pi camera (Sony IMX219). I am using the SCM-QWKS quick startup board. When I plug the ribbon cable of the camera into the MIPI/CSI port and boot up my board, I get the following error:

### ERROR ### Please RESET the board ###

 

I am not sure why when I plug the camera in, I get this error. Looks like there is some i2c issue.
