Configuration of GPIO pins on Port 1 doesn't work

Question

Hey..

I'm having difficulties using P1 pins for UART.

I just changed the blinky example for checking the P1 pin changes with it. But no changes where monitored as expected.

I think the P1 configuration using NRF_GPIO_PIN_MAP isn`t set.
