nrf5340 radio test

[mingjkl]

I'm debugging radio test sample and I'm having some problems.
The first step is to compile NRF / samples / peripheral / radio with SES_ Zephyr.hex in test project.
Second, use west to download zephyr. Hex to the network core.
In the third step, use SES to open NRF / samples / nrf5340 / empty_ app_ Core project, compile and download to the application core.
The fourth step is to open the serial port tool and prepare to send debugging commands.

The serial port returns the following.

Non-secure callable region 0 placed in flash region 1 with size 32.

But I didn't respond to my command. What did I do wrong?

Hi,

serial port returns the following

 Did you check the other serial ports? It might be that the output you are looking at here is the app-core serial port, just running empty_app_core, and you need to be looking at the network serial port?

PS: We recommend using PuTTY when testing the radio_test sample: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.1/nrf/gs_testing.html#putty

Thank you for your reply. After connecting nrf5340dk, three com will appear in the serial communication tool. Do these three com correspond to application core and network core respectively?

 Yes, from this link, we have the following:

When connected to the computer, the nRF5340 DK emulates three virtual COM ports. In the default configuration:

• Logging output from the application core sample is available on the third (last) COM port.

• Logging output from the network core (if available) is routed to the first COM port.

• The second (middle) COM port is silent.

Thank you for your answer. I want to ask another question about radio test. I see that in the project of radio test, in the main (void) of main.c, the first execution is printk, and then clock_ Init (), but I can't see the initialization code of radio and UART. How did UART and radio start to work.

It's initialized with the SYS_INIT macro.
