I am attempting to us the nrf52840 but am unable to interact with any of the GPIO pins on the P1 register. anything on the P0 register works just fine. I have attempted setting the pin number using the NRF_GPIO_PIN_MAP method as well as simply adding 32 to the pin number (as suggested in another post) and am unable to configure any pins on this register as an output. I am using the ble_app_blinky as a starting point, testing a custom board, and programming it via the nrf52DK on segger studio. I am honestly at a loss as to why its not working, have I missed some step needed for that register? I am new to the platform as well as hardware programming (have experience in mobile development).Thank you in advance!
