I've installed the new Buster Lite IMG provided by Kunbus on a RevPi Core 3, in order to create an up-to-date image version of my system.
I'm using RevPiMODio2 to operate the DIO Module which is connected to the Core3.I noticed that with this new OS version, the Power LED on the Core3 goes quite often, in a short intervall time (2-10sec), to RED, then OFF, and then back to GREEN again.
The behavior above happens as a loop, so as soon as it comes back to GREEN, the cycle starts again.
I never had this behavior on Stretch.
Can someone explain what it means? In which system log can I check for more information / the causes of that behavior?
Any suggestions how to debug/find the causes?
Many thanks in advance,
