Description

I am using a custom nRF52 development board that works in all respects. Except when I tried to output a PWM signal like:

void setup() { pinMode(A2, OUTPUT); analogWrite(A2, 200); }

I see zero on A2 (GPIO28). Looks like PWM is busted for the nRF52 DK variant that I am using for my board variant.

Is this a known problem or is there some magic incantation required to get PWM to work with the current Arduino core?

Contributor guide

Research direction
Check the PWM implementation for nRF52, particularly the pin configuration and timer setup. Verify if the pin A2 (GPIO28) is correctly mapped to a PWM channel and if the PWM clock is enabled.
