After upgrading jetson 6.0 to jetson 6.1, the sensor_start_streaming function is not called

[2450732921]

After upgrading jetson 6.0(R36.3) to jetson 6.1(R36.4), the imx415_start_streaming function is not called.

This is my driver source code：

There is no log printout of its calls in the kernel logs：

Hi @2450732921,

Can you please share your VI trace logs after you try to capture?

Hi ShaneCCC

Is this the directory for the platform v4l2 code?

Linux_for_Tegra/source/nvidia-oot/drivers/media/platform/tegra/camera/tegracam_v4l2.c

What is the timing of the call to the code in this file?
How should I view the Log here?

dmesg doesn’t seem to be able to see that the v4l2sd_stream() function is being called:

How should I view the direction of the problem?

Using dev_info() or pr_info() instead of dev_dbg()
