How to define which UART is used by the console?

[Nick_RA]

So I will have 2x physical UART provided on my  board. I am using printk(), and I want to choose which UART handles console traffic by config options.

How to achieve that? All I can see are the boolean options such as CONFIG_SERIAL=y to turn it off or on.

Hi,

You can change this in devicetree. Create a devicetree overlay and change which UART is used by the zephyr,console node:

/ {
	chosen {
		zephyr,console = &uart1;
	};
};

Best regards,
Marte

OK great... I'll be using custom devicetree anyway.
