Hi Vincent,

Thank you for sending your project zip.

After compiling the project, I got the similar error:

"error: static assertion failed: "/soc/peripheral@40000000/uart@a000 has legacy *-pin properties defined although PINCTRL is enabled"

This means that we need to use pin control.

Pin control, also referred to as pinctrl, is a Zephyr RTOS API to standardize how SoC peripheral pins are configured. You can read more about it here: Pinctrl

We need to use pinctrl in overylay. Kindly replace the contents of your overlay with this one:

&uart2 {
	compatible = "nordic,nrf-uarte";
	status = "okay";
	current-speed = <115200>;
	pinctrl-0 = <&uart2_default>;
	pinctrl-1 = <&uart2_sleep>;
	pinctrl-names = "default", "sleep";
};

&pinctrl {
	uart2_default: uart2_default {
		group1 {
			psels = <NRF_PSEL(UART_TX, 0, 16)>,
					<NRF_PSEL(UART_RX, 0, 17)>;
		};
	};
};

And re-buid you project.

Hope it helps,

Naeem

Hi Vincent,

Thank you for contacting DevZone at NordicSemi.

Can you please zip and send your complete project to build and reproduce it. Looks like related to the overylay configuration and pinctrl.

Thanks.

Naeem
