A little update on this, it seems to be broken again on the latest Rasperry OS version
The overlay below now gives the following error
This was working flawlessly on 6.1, even installing this image https://downloads.raspberrypi.org/raspi ... 023-12-06/ it works fine, however after an upgrade, or using the imagers default the above error appears. I have taken a look through a bunch of the included overlays and I can't see anything different. My overlay is below, any pointers would be greatly appreciated!
