I am happy to report that I have solved this problem!
I try to describe my ideas as clearly as possible, and the driver source code and device tree will be open. Hoping to help someone in need~
Problem-solving ideas：
I got the inspiration from Orin Nano, nvarguscamerasrc with tear down effect and tried to change the “active_w” in the device tree file according to the datasheet of IMX327.
When I had the tear problem, I set “active_w=1920” in the device tree. Set1080p-12bit, mode0=30fps, and mode1=60fps in the camera driver. Tears exist in both modes.
When I looked at Pixel Array Image Drawing in Full HD 1080p mode (CSI-2 serial output) in IMX327 datasheet, I tried to change the “active_w”, and finally when active_w=1948, the video displayed normally and without tears. 1948 = 4+8+1920+9+4+3
Open source:
For personal reasons, the source code is not available now. If you need, you can send me an email: xuechengjie98@163.com
I would also like to thank ShaneCCC and James Lee, we were able to discuss ideas to solve the problem together~
