nRF5340: UART0 on netcore

Hi Vidar,

Thank you for your reply, that's ok after including <zephyr/device.h>.

A simple mistake, but a little strange that the DT_N_S_soc_S_uart_41013000 can be generated in zephyr/include/generated/devicetree_generated.h even without include <zephyr/device.h>.

Best regards,
Yanpeng Wu

Hi,

Do you get the same build error if you add "#include <zephyr/device.h>" to C:/dataLogger/hello_world/src/remote/modemtest.c?

Best regards,

Vidar

Hi again,

In the soc device tree, C:\ncs\v2.5.0\zephyr\dts\arm\nordic\nrf5340_cpunet.dtsi, there are:

		uart0: uart@41013000 {
			compatible = "nordic,nrf-uarte";
			reg = <0x41013000 0x1000>;
			interrupts = <19 NRF_DEFAULT_IRQ_PRIORITY>;
			status = "disabled";
		};

In the DK board device tree, C:\ncs\v2.5.0\zephyr\boards\arm\nrf5340dk_nrf5340\nrf5340dk_nrf5340_cpunet.dts, there are:

&uart0 {
	status = "okay";
	current-speed = <115200>;
	pinctrl-0 = <&uart0_default>;
	pinctrl-1 = <&uart0_sleep>;
	pinctrl-names = "default", "sleep";
};

and in the 'chosen' section, the 'uart0' was used several times.

How can I define the UART0 overlay if I want to connect a device(it's an ublox modem in my case) on it?
