I see that the Data format in 'CX3 Mipi Interface Configuration' section is chosen as RAW12. Doing so will cause the MIPI block to drive 12 GPIF data lines and remaining 4 would be sampled as zeros (I assume you would have configured the GPIF to be 16 bit wide in your firmware)
So, to change it you can choose output format as 16-bit and configure the GPIF bus width as 16. Let the 'Data format' in the in the CSI-2 MIPI Inputs section be RAW12 since your image sensor data might be RAW12.
Also look for any errors on the UART and the CX3 configuration tool (Please use the tool which is there in SDK 1.3.4).
Hi, Thanks for you support. I have solved this problem, thanks!
