Currently using the IMX462 camera with Bullseye 32-bit on a RPi4 and all is working well.
I’m running on a PiOS version that has the 5.10.63.V7l+ kernel and the matching Pivariety driver release.
There has been a recent Bullseye PiOS release with a new kernel version of 5.10.92-v7l+
Will there be a matching Arducam driver release at some point so that the PiOS upgrade can be accepted and installed?
I flashed the most recent 32-bit Bullseye image (2022-01-28) and added the up to date upgrades.
Then followed the installation script for the driver installation.
dmesg, dev/video* and v4l2-ctl all showed the expected results.
Then installed the libcamera app and dev packages and tried a libcamera-hello.
Window appeared but no camera image.
Did a reboot and tried libcamera-hello again and all is good. Camera image appeared as normal.
Will now go ahead and install the python libcamera package.
I’ve re-installed the Python libcamera package and all is running well with the new
5.10.92-v7l+ driver. I’ve created a short cribsheet as a reminder how to get everything installed and running and will copy it below in case it helps anyone else.
Instruction cribsheet to get Python libcamera , Opencv and numpy installed to allow demos to run.
These are for my situation of 32 bit Bullseye with Python 3.9 pre-installed.

Click to download the zip folder.
Ignore the Google warning on virus checking and download anyway.
And to follow up the above question,
I tried again to install the driver using the alternative single manual steps and it successfully installed, with just the two video capture formats liste.
However after installing the libcamera and apps I got this message in the log after trying to run libcamera-hello
[0:00:27.635050538]  ERROR IPAProxy ipa_proxy.cpp:149 Configuration file ‘arducam-pivariety.json’ not found for IPA module ‘raspberrypi’

What is the best way to get matching sets of driver and libcamera/libcamera-apps and ideally also the most up to date versions of libcamera and the apps.?
The latest kernel driver is using media-controller, use v4l2-ctl --list-formats-ext to list the formats supported by media,
if you want to check the format of the camera, please use libcamera-still --list-cameras
I’ve reflashed a card and followed the standard installation script for both the kernel driver and the libcamera and apps.
the output from libcamera-still --list cameras is as below:-

All the libcamera apps, hello/still/jpeg and vid are working. Thanks yet again .
But when I try the python demos they fail with the following typical message:-

Thanks again for your patience and assistance!
