February 18, 20251 yr Hello everyone, I am new to this so please forgive my eventual mistake. I have a Rock 4 SE with Armbian Linux 6.12.13-current-rockchip64 (bookworm) for Rockpi 4B (because there is not a special version for SE it re-commanded to use 4B). And I try to use the CSI port to connect a Camera Raspberry Pi V2.1. And I does not work, I have tried to add different value to the overlay in /boot/armbianEnv.txt like overlays=rockchip-csi csi or imx219 with a reboot each time, but it doesn't seem to work. Looking around, it seems like there is a lot of issue with csi camera and rock 4 with armbian (and sometime other os). But none seems to have an answer, but because these are old, 4 to 6 years old, maybe there is an answer now. Looking closely to the overlay, it seems there is no CSI related file in boot/dtb/rockchip/overlay/ it seems possible to maybe create one, but out of my skill right now. So I am desperate for help, if someone can help making this camera work, I would be great full. Running "v4l2-ctl --list-devices" give : rockchip,rk3399-vpu-enc (platform:ff650000.video-codec): /dev/video1 /dev/video2 /dev/media0 rockchip-rga (platform:rga): /dev/video0 rkvdec (platform:rkvdec): /dev/video3 /dev/media1 My overaly : overlay_prefix=rockchip overlays=rk3399-v4l2-video imx219 csi I have try with "," instead of space for overlay value.
