When I perform the "electrical rule check" in KiCAD I get errors at my GND-Symbols.
pin connected to other pins but not driven by any pin
After googling I was presented the solution of going to a "pin property" menu.
Unfortunatelly I don't know how to get to that menu.
I only have the "property" menu of the symbol and I cannot set the "power property" there.
I tried using the "power flag" symbol and the "GND_PWR" symbol but that also produces similar errors.
