In the schematic for the X-NUCLEO-GNS2A1 it shows the SYS_PSS signal going to J 29
J29 shows as being connected to either nothing (PINs 1-2) or "D2D6/PWM" (Pins 2-3)
This is incorrect, the actual circuit is:
PINS 1-2 connect SYS_PPS to D2 on CN5.3
PINS 2-3 connect SYS_PPS to D6/PWM
That's not so bad, it's just a mis-alignment of the text in the schematic.
However the silk screen on the board at J29 shows that PPS can be conneted to either CN9.3 or CN5.7
In fact that should be CN5.3 and CN5.7
