I'm seeing the following error with a V1 camera running latest ArchArm. Even though raspistill complains, it still captures an image and saves it to a file.
$this->bbcode_second_pass_code('', '$ /opt/vc/bin/raspistill -rot 180 -t 3000 -w 1920 -h 1080 -md 2 -e png -o test.png
mmal: mmal_vc_shm_init: could not initialize vc shared memory service
mmal: mmal_vc_component_create: failed to initialise shm for 'vc.camera_info' (7:EIO)
mmal: mmal_component_create_core: could not create component 'vc.camera_info' (7)
mmal: Failed to create camera_info component
')
I also have a python script that uses the PiCamera library, but it isn't as forgiving and raises an exception and exits:
$this->bbcode_second_pass_code('', 'raise PiCameraMMALError(status, prefix)
picamera.exc.PiCameraMMALError: Failed to create MMAL component b'vc.camera_info': I/O error')
In the /boot/config.txt I have:
$this->bbcode_second_pass_code('', 'start_x=1
gpu_mem=128')
I've tried with two different V1 cameras modules & cables which otherwise work fine on Pi3 & Pi2 devices for the tools above. I have some V2 cameras but they are currently in use so can't try them at the moment.
Any ideas?
