Hi Dannis,

Here is how to redirect the shell specifically to another uart:

/ {

	chosen {
		zephyr,shell-uart = &uart1;
	};
};

This will need to be added to your overlay.

Kind regards,

Håkon

Hi Sir

Best Regards

Hi,

When using uart0 for a specific task, in this case the shell, you can setup uartX freely, but please keep in mind that uart instances are shared resources.

This means that when uart0 is enabled, spi0 / i2c0 must be kept disabled.

Here's a section on how to setup a generic async uart:

Kind regards,
