Okay, after getting that installed, atleast the driver is trying to get loaded but then it gets stuck,

[ 8.477873] imx219 5-0010: supply VDIG not found, using dummy regulator

All I can find online is this topic: RPi Cam V2 (Sony IMX219) w/ Edge AI Demos - #31 by Alaa_Abdelmoneam
Which doesn’t seem to have gotten very far :/, Is the R5 you’re referring to the camera revision or the board revision?
