IMXRT 1170 1 Lane MIPI vs 2 Lane MIPI with OV5640?

Hello,

I'm actually trying to get the MT9M114 which is exclusively 1 lane MIPI to work with the IMXRT1170, but using the OV5640 as a prior step to determine if using 1 lane is even possible.

As far as I can tell, on the NXP side the only change that needs to be made is switching the define from 2 lanes to 1?

I sent the command to the OV5640 to tell it to be 1 lane MIPI in the ov5640.c driver

I'm debugging using LVGL onto the display.
I am also using the test pattern on the camera to make my life easier.
Here's the output I expect, and get when the camera is set to 2 lane MIPI

However this is what I get when I setup for 1 lane MIPI:
(640x480 VGA, 30 FPS)

It seems like the first 8 horizontal lines are correct. Then there's an offset?
As much as I like Tetris shapes, I'd like to fix this issue.

Thanks for any suggestions / help.

Mike
