I am putting together a stereo camera platform using two Alvium 1800-158C cameras (IMX273 sensor) allied vision github and a Jetson Nano. I have a custom carrier board with two 22pin MIPI connectors to connect to the cameras which is based on the Ant Micro open source Jetson baseboard Ant Micro Github.
I have followed the instructions to build and install the Alvium drivers on the Jetson Nano. However I have a few errors that must be rectified.
From the kernel log

I have a few questions:
- What does the modalias failure mean and what can cause it?
- How can I start to debug the i2c error register dump?
I have not been able to find relevant documentation for either error and would appreciate any help.
If you need clarification on something, please let me know.
