Hi everyone,
I have the STEVAL-IDP005V1 sensor board on which STM32F469AI MCU is present. I suspect that something is wrong with the D9 pin of MCU which is supposed to receive 3.3V from the power management unit on the board which I tested to be up and fine. However the packaging type of the MCU does not expose any pins to be used for debugging and there are no coupling capacitors to that pin (from schematic).
So how can I test that pin without damaging the MCU?
Thanks in advance
