I want to check mipi state like crc_err with c/c++ code, Is there an example here?

If you are using v4l2-ctl, then you can check the TRM to read the status in csi5_fops.c

Thanks for your reply, it likes NVCSI_STREAM_0_PH_WC_0…。
now i want to set cil_settletime/numlanes in driver, i see a struct sensor_signal_properties in tegra-v4l2-camera.h, can i update it?

You should modify the device tree to apply it instead of hard code it.

Thanks

I mean like this tpoic question: How to change nvcsi setting (such as cil_settletime,lane num) after kernel boot? - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums

If you are using v4l2-ctl then you can do that but Argus base APP.

Thanks

yes, i use v4l2-ctl, but sensor_signal_properties is readonly.
other properties like bypassmode, sensor_mode i can set.
I want to set cil_settletime 、num_lanes、discontinuous_clk..
this csi properties in code

You can set it in csi5_fops.c

How to call a function after adding it in csi5_fop

You can set the cil_settle time by your define instead of read from the device tree in csi5_fops.c
