Dear All,
Imx6q+Tw9900 (output YCbCr 4:2:2 ).
If config DAT12~DATA19 pin as camera data input, all works fine。
I changed csi0 data pin from DAT12~DATA19 to DAT4~DAT11 now, but can not capture video data。
How to use DAT4~DAT11 to replace DAT12~DATA19?
Hi echo
there is no way to change it, but one can try other configurations
given in sect.4.11.10.1 IPU Sensor Interface Signal Mapping i.MX6DQ Datasheet

Best regards
igor

For BT656 interface mode (EAV/SAV on data line), the data must be input from CSI_DATA19 ~ CSI_DATA12.
If you must use CSI_DATA11 ~ CSI_DATA4, then you can use VSYNC/HSYNC mode to capture, it needs 16 bits generic mode to capture the data from CSI_DATA19 ~ CSI_DATA4, then software needs drop the 8 bits MSB in memory.
From CSI side, the data will always to receive from DATA19, the MSB. This can't be changed.
