having touched into the subject before concerning the configuration, I still have not been able to confirm that the shutdown-script is running in the background.

Usually when the primary source is detached, the timer shown in the configurator-program starts counting down, but the pi abruptly usually just crashes, or goes to black a second before timer runs out.

Have 20 sec as timer for the power, and 10 sec (default) for the shutdown-script.

RC.local has the following added at the end:

/usr/local/bin/rpi4pci.sh
python /home/pi/RTCSerial.py [&]

python /home/pi/serialShutdown.py [&]

exit 0

The following command in Terminal: pi@openauto:~ $ ps -aef | grep python

shows the following:

pi [nbsp] [nbsp] [nbsp] [nbsp] 801 [nbsp] [nbsp] 1 [nbsp]0 13:15 ? [nbsp] [nbsp] [nbsp] [nbsp]00:00:02 /usr/bin/python3 /usr/share/system-config-printer/applet.py

Hello Mirrormurr,

there is the "[&]" missing in your rc.local.

furthermore our python scripts are designed for python3, you should run them in rc.local with python3 too

so it should look like this at the end of your rc.local:

/usr/local/bin/rpi4pci.sh [&]

python3 /home/pi/RTCSerial.py [&]



python3 /home/pi/serialShutdown.py [&]



exit 0

Hello again,[nbsp]

The missing "[&]" seemed to have escaped my copy-and-paste..

Adding the python3 didn't seem to do the trick either. Am getting the same result,[nbsp]

How could we proceed?

Hello Mirrormurr,

unfortunately, we cannot reproduce the error here. It could be the rpi4pci.sh file which should be executed as well.

We recommend removing this file from the autostart for testing to see if this is causing the problem.

You can also try again with a fresh set-up Raspberry Pi OS, set up according to our quick start guide, or use one of our prepared images from our download section. To rule out causes in your existing setup.

Best regards[nbsp]
