Did you follow the guide here on how to connect to external MCU?

Hi! thanks for your response.

Now I can build the SLM without errors. The thing that I did is just build the SLM sample with the nrf9160dk_nrf9160_ns board option and then just modify the UART0 pins to match with my custom board and let the other interfaces, buttons and leds in the overlay.

I can flash my board but I don't have communication with the MCU via UART. What I'm doing wrong?

The only changes that I did in the overlay were:

UART 0 TX --> P0.06

UART 0 RX --> P0.05

UART CTS --> P0.14

UART RTS --> P0.15

I'm totally desperate for not being able to get it to work... is there something that I'm missing in my MCU FW related with the CTS/RTS pins?

thanks in advance!

Hi!

Do you get the same errors for when you built for the nrf9160dk_nrf9160_ns and your custom nrf9160_sica_b1 board?

What changes did you make in order to get a build error when building for the nrf9160dk_nrf9160_ns ?
