Hi, xianfei.chen

Perhaps you can remove the below image dtsi configuration, as it will override your port index configuration.

This dts has been deleted。I put Pix_ Clk_ If hz=“300000000” is set in this way, it will not be able to start. Is our PCLK restricted and unable to receive data? Our PCLK can actually reach over 800000000

I can’t boot up if I refer to this topic configuration

Hi,
I’m not asking you to delete the file, but to comment out the code where I drew the red box.

We didn’t use this dtsi, attached is our dts

配置了overlay还是无法正常取图

kernel/dtb/tegra234-p3737-camera-ox03c10-overlay.dtbo

Does the trace log the same?

Yes ,do you have any suggestions?

Due to the trace log tell didn’t receive any validate data from the sensor.
It could be the HW problem if the port-index/bus-width are correct.

Thanks

but The waveform on the data line looks fine

How to determine if overlay is effective

You can dump the device tree to confirm it.

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree
