enable CSI port on latest raspi OS (bookworm)

2025-05-29 20:32:32 Ask

i cannot seem to enable CSI/DSI ports on the cm4 to 4b adapter board running the latest bookworm release of pi os. i followed your instructions in the guide and tried to use dtc to compile a dt-blob.bin file in /boot folder but i get a ton of warnings as console output during this process. it still creates a dt-blob.bin file in /boot yet it doeasn't seem to work as i cannot get any camera to work connected to the CSI port on your board. it seems the files in your guide are extremely outdated and major system processes have changed since. hence all the errors compiling them...


best regards

Hello, if you are using the OV5467 camera, you don't need to add any additional configuration. You can try connecting the OV5467 interface to cam0 and then activate the camera through the command line with: libcamera-hello -t 0 or libcamera-hello. If you encounter an error or no response, you can try checking if the camera is detected using: libcamera-hello --list-cameras.

If you want to test the cam1 interface, try using: libcamera-hello --camera 1.

If your camera is a different model, you need to add system configurations by running:

sudo nano /boot/firmware/config.txt

Then add:

dtoverlay=ov5647,cam0

dtoverlay=imx219,cam0

dtoverlay=ov9281,cam0

dtoverlay=imx477,cam0  

After restarting, follow the same steps to test the camera.
