Hi @JerryChang,
I probed the signal and found that there was no signal on data lines, I have fixed that but still I don’t see anything when I use this: v4l2-ctl --set-fmt-video=width=3264,height=2464,pixelformat=RG10 --stream-mmap --stream-count=1 -d /dev/video0 --stream-to=ov5693.raw Trace log is as below:
