So I have a Pi-Cam and a Raspberry Pi 3 B+, and I'm trying to get them to work together. Note: This camera has worked many times before today's errors.

A few things:

  • The voltage is fine (red light is constantly on)
  • The camera is plugged into the CSI port (in between HDMI and Ethernet)
  • The metal strips on the camera are facing towards the HDMI port
  • I've tested the camera with another raspberry pi, but I'd like to use it with this Pi.
  • The camera is enabled from sudo raspi-config > Interfacing > Camera

The CSI connector (that little white piece at the top) is a bit broken and will fall off quiet readily if the camera is not attached. Would this be an issue?

Here's the error when I run raspistill -o image.jpg: 

mmal: Cannot read camera info, keeping the defaults for OV5647  
mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM)  
mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)  
mmal: Failed to create camera component  
mmal: main: Failed to create camera component  
mmal: Camera is not detected. Please check carefully the camera module is installed correctly

Is there anything else that I could try to get this camera to work?

  1. Check vcgencmd get_camera this command. It will return how many cameras supported and detected. Normally you will get "supported=1 detected=1". If you get detected=0 then camera not detected.

  2. Recheck hardware connection.

  3. Try setting gpu_mem=128 in /boot/config.txt

  4. Enable I2C interface.

If not work, try with a different camera.

  • 4 is not necessary, but /boot/config.txt should contain start_x=1. Or just enable the camera in raspi-config... BTW If enabled=1 then gpu_mem and start_x are fine (otherwise enabled would fail) – Dirk Dec 30 '18 at 8:20
  • Thanks for the help! I eventually relented and switched to a different camera. – JoshDaBosh Jan 30 '19 at 1:15

Try vcgencmd get_camera to get the status of the camera, if you see detected = 0 open the "Raspberry Pi configuratios" in preferences menu and enable the Camera along with I2C, reboot and it should work.

    Where can I see detected = 0? – Ingo Sep 8 '20 at 11:28
  • use vcgencmd get_camera – Satyam Pandey Sep 9 '20 at 13:14

I agree with the above on a reset of the preferences - It now works.

Oddly, detected = 0 is still shown but camera = 1.

This worked for me.

"Try vcgencmd get_camera to get the status of the camera, if you see detected = 0 open the "Raspberry Pi configuratios" in preferences menu and enable the Camera along with I2C, reboot and it should work."
