The CSI controller doesn't seem to work properly at the default clock rate of 600 MHz. Dropping it down to 300 MHz, the default rate used by the BSP, fixes things. The BSP also tries to use different clock rates (multiples of 108 MHz) according to the captured image size. I've not tried this since the driver no longer exports sub-device controls, and I currently don't know how to handle that to change the resolution. Regards ChenYu
