Hello,
I am working on a YUV422-10bit sensor connecting to CX3 with YUV2 output. The sensor resolution is 1280x720@30fps, I find that MIPI CSI-2 transfer YUV422-10 as 2 pixel with 5 bytes, so I think I could still configure CX3 as YUV422-8 input, but configure resolution to 1600x720. In this way, CX3 still can receive complete sensor data I think(if this is wrong, please correct me). And I actually done a test, but the result is quite abnormal. I print CX3 debug log, and found CX3 have received sensor data with different frame size, the frequency is also unequal, and preview all black image with AMcap. So if anybody could help me?
Attachment is MIPI interface configuration and debug log.
Solved! Go to Solution.

Hello,
As the data from the sensor is in YUV422 -10 bit, please use that as the input format instead of the YUV422 - 8-bit format. Also, please use the same video resolution (1280 * 720) in the MIPI configuration tool.
Please confirm if REFCLK on the CX3 board is 24 MHz. To debug the problem, we would suggest keeping the pre-divider value as 3 and tune the other fields to get the PCLK - 100MHz
Please refer to this KBA Steps to Setup up MIPI CSI Camera Solution with CX... - Infineon Developer Community for generating the firmware using the CX3 MIPIReceiver configuration tool
