Hello together,
I’m preparing my first project in KiCAD and struggle a bit with the ERC check. In my schematic there are two separete grounds GND & GND1. The ERC reports that on IC - U1 PIN9 and Pin14 connects to the same Output Voltages.( First Error )
Both PIN should be connected to GND1.
Therefore I linked a PWRFLAG to GND1:
Unfortunatly the error message increases.
How can I indicate the GND / GND1 nets correctly as power routings?
Kicad Version: 7.09
Thank you.
KiCad is complaining that two outputs (or power outputs, my German is not very good) are connected, and this is not allowed for ERC. See: Schematic Editor / File / Schematic Setup / Electrical Rules / Pin Conflicts Map
When I look at the schematic symbol for an LM7805, then it’s GND pin is defined as a power input.
So, U1 in your schematic has some errors. It also looks ugly (with pins resembling the package, instead of function, so it’s time for a re design. 
I changed the schematic symbol. Now GND is defined as power input. Thanks to your support, the ERC shows no errors now.
