Raspberry Pi 4 and raspistill breaking with mmal issues #399

Open imrehg opened 5 years ago

imrehg commented 5 years ago

Tested 2.41.0+rev4 Raspberry Pi4 with raspistill, it is not snapping pictures, and does these errors:

24.09.19 11:50:16 (+0100)  camera-new  snapping a picture via raspistill -o /data/test_new_20190924_105016.jpg

Actually, seems like it still takes a picture properly, so this is more of a warning? But unsure where is it coming from, or how to fix it yet.

i had similar problem with balenaOS 2.73.1+rev1 on rpi4 when i execute camera = PiCamera() from python:

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) Traceback (most recent call last): File "src/main.py", line 21, in camera = PiCamera() File "/usr/local/lib/python3.6/site-packages/picamera/camera.py", line 367, in init with mo.MMALCameraInfo() as camera_info: File "/usr/local/lib/python3.6/site-packages/picamera/mmalobj.py", line 2346, in init super(MMALCameraInfo, self).init() File "/usr/local/lib/python3.6/site-packages/picamera/mmalobj.py", line 633, in init prefix="Failed to create MMAL component %s" % self.component_type) File "/usr/local/lib/python3.6/site-packages/picamera/exc.py", line 184, in mmal_check raise PiCameraMMALError(status, prefix) picamera.exc.PiCameraMMALError: Failed to create MMAL component b'vc.camera_info': I/O error

the rpi4 was working properly for 5 days straight when suddenly it stopped after pushing new code without updating Dockerfile.template.
