Hello, I was able to detect Camera Module 3 on a Pi 4 running balenaOS 5.2.8, using this example: GitHub - balena-io-experimental/libcamera-apps: Example repo to showcase Raspberry Pi's new libcamera stack on balenaOS
Just be sure to increase the GPU memory to at least 64MB - in the “Define device GPU memory in megabytes.” setting in device configuration. I made no other config changes or additions.
