Ok. Since v2.0.0 we started using pinctrl, so the way you should set up your overlay file is slightly different.
If you are building your network core image as a child image, you need to create a folder named "child_image" in your project and place the overlay file for the network core there. It should have the name of the project running on the network core, for example hci_rpmsg.overlay
The network core overlay file should look something like this:
&pinctrl { uart0_default_alt: uart0_default_alt { group1 { psels = <NRF_PSEL(UART_TX, 0, 31)>, <NRF_PSEL(UART_RTS, 0, 29)>; }; group2 { psels = <NRF_PSEL(UART_RX, 0, 30)>, <NRF_PSEL(UART_CTS, 1, 10)>; bias-pull-up; }; }; uart0_sleep_alt: uart0_sleep_alt { group1 { psels = <NRF_PSEL(UART_TX, 0, 31)>, <NRF_PSEL(UART_RX, 0, 30)>, <NRF_PSEL(UART_RTS, 0, 29)>, <NRF_PSEL(UART_CTS, 1, 10)>; low-power-enable; }; }; }; &uart0 { status = "okay"; current-speed = <115200>; pinctrl-0 = <&uart0_default_alt>; pinctrl-1 = <&uart0_sleep_alt>; pinctrl-names = "default", "sleep"; };
You will also need an overlay file for the application core, placed in the project folder or a "boards" folder.
This is to forward the required pins to the network core:
&gpio_fwd { compatible = "nordic,nrf-gpio-forwarder"; status = "okay"; uart { gpios = <&gpio0 31 0>, <&gpio0 30 0>, <&gpio0 29 0>, <&gpio1 10 0>; }; };
