Hi, everyone.I use ov2659 camera sensor connects with my custom iMX6ULL board.I directly used driver/media/i2c/ov2659.c code on linux kernel.The image has been displayed.But the image has two problems:

1.It has a bar on left

2.the image been split

I use ov5640 to test the hardware bus.The ov5640's picture is correct.

The below picture is snapshot form ov2659.Is it timing wrong on ov2659 driver of other thing?

Which unit test? I had test more resolutions by driver supported.The 800x600 is right and others are same issue on that.

we haven't tested this driver you use, I don't know if the driver has any issue or not, you can refer to the driver of ov5642, I post the topic about this camera, but the customer don't share the experience there, but you can refer to it.

Thanks again.And I also happened another problem on ov5640.I got a new ov5640 camera and connect it with my imx6ull board.I found only 800x600 resolution is correct.Other resolutions have difference issue, such as picture has spilled four picture, a bar on left of the picture.
