Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

  • DietPi version | 9.10.0
  • Distro version | bookworm 0
  • Kernel version | Linux paisley 6.6.74+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.74-1+rpt1 (2025-01-27) aarch64 GNU/Linux
  • Architecture | arm64
  • SBC model | RPi 3 Model B+ (aarch64)
  • Power supply used | Geekworm X-UPS1 (4x 18650 UPS)
  • SD card used | Samsung EVO Plus

Additional Information (if applicable)

  • Software title | (EG: Nextcloud)
  • Was the software title installed freshly or updated/migrated?
  • Can this issue be replicated on a fresh installation of DietPi? It is occurring on a fresh installation of DietPi (but I have not tested on another).
  • Bug report ID | echo $G_HW_UUID

Steps to reproduce

  1. Connect Camera Module 3 to CSI port of Rasperry Pi 3B+
  2. Enable RPi Camera under dietpi-config > Display Options
  3. sudo apt install rpicam-apps-lite

It should be noted that I did this on a headless install of DietPi.

Expected behaviour

  • rpicam-hello --list-cameras should show the connected camera device, OR
  • vcgencmd get_camera should show the connected camera device, OR

Actual behaviour

$ rpicam-hello --list-cameras
Could not open any dmaHeap device
No cameras available!

$ vcgencmd get_camera
Can’t open device file: /dev/vcio
Try creating a device file with: sudo mknod /dev/vcio c 100 0

$ ls -l /dev/vcio
crw------- 1 root root 10, 125 Feb 20 17:32 /dev/vcio

Extra details

Installing mjpg-streamer and/or motioneye (not sure which, I installed both at the same time) appears to resolve this problem? After installing them, I now see:

$ ls -l /dev/vcio
crw-rw---- 1 root video 10, 125 Feb 20 17:32 /dev/vcio

$ sudo usermod -aG video dietpi

$ rpicam-hello --list-cameras

$ vcgencmd get_camera
supported=1 detected=0, libcamera interfaces=1

However, I couldn’t get either package to work. Per this thread, mjpg-streamer installs without the cruicial input_raspicam.so plugin, and so it fails to start. Motioneye launches and I can access the web interface, but adding a camera just shows a broken/empty video stream.
