I have follow the implementation guide to build the hello_world example and build using the following command
west build -b nrf5340dk_nrf5340_cpuapp samples/hello_world
and try to listen /dev/ttyCAM0 using minicom, but thers's still no output on console
And another is the the youtube demo on https://youtu.be/uqKxmsrP2Hc
on this video, how these pins are connected to? it's sort of unclear on the video
