I get this error when I run 'raspistill -t 2000 -o image.png -e png '
mmal: Cannot read cameara 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
I would double check that the camera is correctly connected at both ends and not loose, and that it is enabled via the RPI config menu. The RPi+ camera draws about 260 mA more current than the board so you need a large enough power supply to support the added load.
After the camera is enabled, you also need a reboot. Check that /boot/config.txt contains the lines:
start_x=1
gpu_mem=128
This will confirm if the camera is properly enabled. If the GPU memory is too small the camera will not work. Also try running a sudo rpi-update.
There are two ways of accessing the camera: Through the Broadcom specific MMAL library, which is used by raspistill and raspivid, or via Video4Linux2, which is a cross platform standard. If you have V4L2 installed then you can try to access the camera through that driver to see what happens. V4L2 should come pre-installed on the latest Raspberian OS. You can check by typing which v4l2-ctl. Normally it is /usr/bin/v4l2-ctl, otherwise try a sudo apt-get install v4l-utils.
To enable it to access the camera, you should first load the driver module by typing
sudo modprobe bcm2835-v4l2.
This should create a camera device at /dev/video0.
You can then get information by typing
v4l2-ctl --all.
This will list a huge amount of information about any cameras in the system and their settings and drivers. And by typing
v4l2-ctl --device=/dev/video0 --list-formats-ex
you can determine the list of frame sizes and frame rates supported.
There's also the possibility that you have a faulty camera board.
Maybe the camera is disabled eg. using a new image. To enable the camera run:
sudo raspi-config
At the blue screen, select interface point and enable camera.
And finally reboot the raspberry.
sudo reboot now
sudo apt-get update && sudo apt-get upgradeto make sure you are running with the latest software.
