Thank you, Simon - that solves it.

I had checked the device tree before to figure out which pins uart1 was wired to by default but missed the 'status = disabled' line.

Hopefully the wizards who are developing zephyr will find a way to include more helpful error messages for device tree problems.

Best regards,

Jan Erik

Try to add the following to an overlay named nrf5340dk_nrf5340_cpuapp.overlay

&uart1 {
	status = "okay";
};

When you've done that, check the file <sample>\build\zephyr\zephyr.dts and search for "uart1" to see if it has taken effect.

Best regards,

Simon
