Back to the original talk - GPIO. I found on Edgerouter Lite pin 11 is used for reset switch - aka 'Factory Default' button. Status is pin 11: 1 F/D<IN>, caps:<IN,OUT> when not pressed and pin 11: 0 F/D<IN>, caps:<IN,OUT> when pressed. However, I found a problem with ethernet driver. It works only in gigabit mode - connected to 100baseT switch is correctly negotiated, it seems, but no traffic flows, either way, probably. What could I do to diagnose root cause of this problem?
