Hi
I loaded the zero bootloader on M0 board.
It is unable to command D2 in any way.
In the schematic is the same, but there is a mistake in the description of the label.
Where is the mistake or Bug ?

By mistake, the digital pins 2 and 4 are swapped at the Arduino M0 (Pro). See here:

Now I understand, but the scheme is wrong.
On scheme, D2 Named PA14, is connected to PA8
