PiCamera errors with Serial enabled?

Fri Jun 28, 2019 9:26 pm

Still working on my Pi3 projects while waiting the shiny new 4 becoming available in my country. Today I decided to expand my security camera project with StromPi, but it requires Serial Port + Console to be enabled. While still working on to get StromPi work as intended, I ran into a problem which was that my old stalking script no longer worked. I took the StromPi off the GPIO at this point and started troubleshoothing with

Code: Select all

sudo vcgencmd get_camera
and got

Code: Select all

supported=1 detected=1
so no problems there. Next I tried with raspistill and got:

Code: Select all

mmal: mmal_vc_component_enable: failed to enable component: ENOSPC
mmal: camera component couldn't be enabled
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates
So here is where it got interesting. I decided to reverse my progress and disable Serial Port and Console just in case, rebooted and tested again. The camera worked again as if nothing was ever wrong!

But why would Serial enabled interfere with the PiCamera's functioning? Am I missing something?
