Hello.
I have a nRF9160DK.
I want to try this uart example: https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/uart
I want to config the nRF9160 uart pin to P0.17 P0.18 P0.19 and P0.21 so I can communicate with nRF52840 on the nRF9160DK through uart.
I changed the uart0 pin config in nrf9160_pca10090.dts files in zephyr and nRF52_P0.13 and nRF52_P0.24 already set to 1 but nRF9160 uart can't work with P0.17 P0.18 P0.19 and P0.21 pins.
Can you tell me how to config uart0 pin config of nRF9160.
