Re: V4L2 output frame abnormal (bcm2835_unicam + ov5647)

I am using raw 8 bit mode + VGA.
I read the linked shared by you so it seems clear that there are issue in 8 bit mode.
First i will try with 10bit mode on current pi ov5647 code base. If same result will check with 5.4 kernel as suggested.

Thanks for your input
