Hi,

(Updated)

I think it's fixed/changed on the DK. If you use 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

It is possible. Please see this case. For nrf5340pdk_nrf5340_cpuapp, you should run the empty_app_core sample. On nrf5340pdk_nrf5340_cpunet, you run your hello_world.

is logging not possible in the net core? I need to develop this application for the net core so I figured I would start there

Hi,

You should develop an application in the application core. Please see this tutorial to develop hello_world on nRF5340 app core.

See how-to-use-rtt. documentation to get the logging output using Real Time Transfer (RTT), modify the configuration settings of the sample to override the default UART console:

CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n

If you want to develop an application in the network core, you can refer to network-samples.
