hi,@JerryChang.
About Sensor Pixel Clock, there is multiple methods to calculate pix_clk_hz, now i choose the way of Using sensor CSI lane output rate.
So i have a question about this, how should i select it correctly.

hello JerryChang:
i still can not resolve this problem, but i try to use the same camera by fpc in nx carrier board, it work normally.
So may it is the reason that hardware design in csi layout and route?

hello ultwcz1997,

may I know exactly what’s the difference, are you having a customize carrier board design?

我用英语表达可能不是很清晰，我用中文描述下：
之前摄像头不能使用的是自己设计的底板，现在我将一个使用fpc连接方式的ov9281插到原来的底板上，然后更改设备树

只是将其中的部分属性替换适配ov9281的驱动。这样操作摄像头是能正常工作的。
