Which NCS version do you use? I have the same problem when I try to build the sample from the command line with cmake/make. But it works fine if I import it to the SES (segger embedded studio).

The cause of the problem for me is that the "device_get_binding("LPUART")" fails.

I use nrf connect in visual studio code. Why does lpuart not work?

I am getting this error now.
