No /dev/video0 after connecting sensor camera

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Orin
1

Good morning,
we have a custom camera sensor based on Sony IMX675 that we have already succesfully integrated and tested on Jetson Orin Nano.

In order to use the camera on Jetson Orin AGX we realize a custom CSI Camera Interposer module following the document "NVIDIA Jetson AGX Xavier Series and Jetson AGX Orin Series Camera Module Hardware Design Guide ".

In order to use the TCA9548 mux and enable the camera i modified and add the attached device tree file, following the files for IMX274.

After the boot i can successfully probe the sensor, so the I2C communication should be ok, but I cannot see the /dev/video0

The system is based on Jetpack 5.1.1 L4T R35-3.1

My guess is that I need to edit some other dts file. Any suggestions about the issue?

Regards

Good morning,
I moved on a bit editing the device tree files. Now I have /dev/video0 and /dev/media0

Now the problem is that I have errors when I try to capture frames with

v4l2-ctl --set-ctrl bypass_mode=0 --stream-mmap --stream-count=10 -d /dev/video0

Enabling the traces I had the following lines

Any suggestion?

hello liviolima80,

here’s PHY interrupt, the error code meant LP sequence error detected on data lane.
normally, it should follow by LP11->LP01->LP00->LP11 sequence. so, it’s more like a hardware issue.

Thank you @JerryChang ,
I found the issue. It was the “lane_polarity” field defined in sensor confoguration.
