How to config ar0231@0x50 video0 work in 3 lane mode

I want to config ar0231@0x50 video0 work in 3 lane,below is my dts file, I can not receive data from mipi,I can confirm camera work in 3 lane mode.

I don’t think there’s a sensor support 3 lanes DPHY configuration.
You can configurate by the bus-width in device tree for 1/2/4 lanes for DPHY.


I use a mipi generator device(not a sensor) to generate 3 lane mipi signal. So I think 3 lane mipi tx is ok. I want to know if xavier support 3 lane configuration.

Xavier DPHY don’t support 3 lanes.


I change the dts config to 2 lane ,but I still can not receive mipi data .
Below is my modify,and the whole dts file .Please help me to analyze the problem.

Do you configure the mipi generator by 2 lanes too.
Check the trace log.

Now I can capture image from mipi generator in1 lane mode .
But I can not receive data from 1 lane sensor .
Below is the trace log.

The error tells SOT multiple error. Check the settle time.

Do you mean it is a hardware problem,or a configuration problem in xavier?So what should I do now,I find a settletime configuration in dts file,should I change this params .

No, I mean the sensor output signal need to follow the MIPI spec like above picture.

Ok I see.It is cause by mipi signal quality or sensor configuration? Do you mean I should change the sensor mipi dphy configuration.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Is this still an issue to support? Any result can be shared?
