I am working with i.mx6ull csi with tw9900 over bt.656. My camera is NTSC format.

I patch mx6s_capture.c file following guidance(0001-Enable-CSI...) from below link.

imx6ul tw9990 issue 

However, I am unable to get the correct image format. This is what I can capture so far.

Attached herwith the source code on mx6s_capture.c as well as tw9900.c

Hi tk

had you got it working with adv7180, unfortunately I am not aware

of tw9900 patches. In general one can try with various modes, like pal,

interlace.and progressive modes of sensor.

Best regards

Hi tk

yes subdev (refer to attached files), ADV7180 used PAL, YUV4:2:2(UYVY) interlace output
connected to CSI_DATA[9:2], so one can set similar settings for tw9900.
