NO console output using nrf5340dk(ttyACM0)

[super6602]

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

Hi, 

Do you program the image with the command west flash --recover?

What is the version on the white sticker of the DK? Is it 0.11.0?

Do you check all the three virtual COM ports?

it works on /dev/ttyACM2, thanks

by the way, on this video,

https://youtu.be/uqKxmsrP2Hc

why it needs to connect TxD to P0.25(or P0.26? actually, the board layout was sort of not clear)

Hi, 

Because it's PDK used in the video. It's fixed/changed on the DK, but on the PDK you might need to connect some external wires, http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.4.0/nrf/ug_nrf5340.html#getting-logging-output
