Porting driver from imx274 to imx334.
12bit rggb bayer, 3840X2160 30fps.
Set gain/exposure/fps functions to dummy.
Save raw image successed by
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=RG12 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ss.raw
But if run
gst-launch-1.0 nvarguscamerasrc ! fakesink
Desktop will hang then reboot.
