You claim in your comment that it from BSP, even "Chen-Yu Tsai" mentioned the same. (Chen-Yu, can you comment here) > "operates properly", yet in your previous mail about this, you were > saying that 1080p @30Hz is broken. Which one is it? 1080p is broken from sensor end, ie what I mentioned on the respective mail.
