IMX412 Camera Stream Timeout - I2C OK but Signal Lost/No Input Detected

I am attempting to bring up an IMX412 sensor on devkit. While I2C communication seems to work perfectly, I cannot get any video stream.
Sensor: IMX412 (4-lane MIPI configuration).
I2C Communication: Successful. I can write 231 registers and verify 0x0100 is 0x01
Driver: i use driver linux-jammy-nvidia-tegra/drivers/media/i2c/imx412.c at oe4t-patches-l4t-r36.4.4-1012.12 · OE4T/linux-jammy-nvidia-tegra · GitHub and i just modify a little
Streaming Failure: Both v4l2 and GStreamer result in a 2500ms timeout
Error Logs:
tegra-camrtc-capture-vi tegra-capture-vi: uncorr_err: request timed out after 2500 ms tegra-camrtc-capture-vi tegra-capture-vi: err_rec: attempting to reset the capture channel

Do you review the device tree config for the connection like port-index/bus-width?

Thanks

i’m set

port-index = <0>;

bus-width = <4>;

data-lanes = <0 1 2 3>;

media-ctl -p like:

i was test with slot cam0 and cam1 on jetson

Looks like doesn’t receive any data from the sensor.

It could be the HW or incorrect port-index.

9

Could this issue be related to the clock configuration or another cause? I have already tried port-index 0 and 2, as well as tegra-sinterface a and c, but the problem persists

You need to make sure the HW connection to config the port-index.
