Hi All,

We are trying to develop sensor driver code for hdmi2csi adapter. But we get some error related to Mipi caliberation.

The calibration timeout should not the root cause.
Follow below link to enable trace for more information.

Hi ShaneCCC,

thanks for your response.
We followed the steps to enable for more debug message.

But we didn’t get any useful information.

From the trace log there’s no any validate data from the mipi bus. You should probe to make sure the mipi output is output data well.

5

Shall we leave/ignore the mipi cal timeout error? or It must be solved to receive the data in mipi csi further.

6

It’s could be ignored.
