We are trying to creating a camera driver for the IMX172 image sensor. We are able to get the camera running at a slow framerate, but whenever we try to increase the framerate we get a green or black screen when starting the video. When we check the camera board, pixels are flowing over the MIPI interface, but they aren’t syncing to frames on the TX1.
I would like to be able to inspect the CSI and VI error registers (VI_CSI_0_ERROR_STATUS, etc), but they aren’t printing out to kern.log. Is there a debugging flag I need to enable for these to be printed, or do I need to add some printk statements to the driver to list their values?
