AR0234 on Cam1 and SPI

Hello!

I have an AR0234 from Arducam which runs on CAM1. I use their installers which modifies the kernel, and then use their v4l2 and opencv to stream.

When I go to activate SPI for a thermal camera I’m attaching using sudo /opt/nvidia/jetson-io/jetson-io.py, set it to SPI1, it disables the AR0234, which probably relies on the same I2C channel.

Is there an easy way to fix this without having to go through the .dtb?

Suppose jetson-io won’t override the camera configure.
Try dump the device tree before and after running jetson-io to compare.

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

Yeah, I was hoping to do this without having to go through the device tree files, but I’ll take a look.

I’ll be back.
