How to enable nCS printf statements on SES in debug terminal

[Ubaid_M]

Hello,

I am using sample hello_world app in SES, in the main file of which there are two print statements as:

    printf("Hello... \n"); \\I added
	printk("Hello World! %s\n", CONFIG_BOARD);

During flashing and debugging on the board, execution enters the above lines, but I see no statements on SES debug terminal.!

Kindly inform on how I can enable outputs on debug terminal.!

Thanks,

Hi

I assume this is the NCS_version\zephyr\samples\hello_world you're referring to?

I think this is because the Hello World message is printed over the UART backend instead of the RTT backend (which the SEGGER debugger uses). You can try setting the CONFIG_LOG_BACKEND_RTT to 1. See more on that in the logging user guide here.

Best regards,

Simon

Hi Simonr,

Thanks for the info, kindly guide me how I can get printf and printk statements to be visible on VSCode..?

Hi

I assume you use the nRFConnect extension pack for VS code, correct? If you also instal the nRF Terminal extension you get a serial terminal called NRF TERMINAL in the Terminal panel. You can connect to your device over serial port (UART) or RTT.

Hi Simonr,

I do have the nRF Terminal installed

But yet I do not see any  printf's or printk's on the terminal.

Great, in the nRFConnect extension, at the bottom left there is a tab of connected devices where you can see your connected DK for instance. You need to choose the COM port you want to see in the NRF terminal in order for anything to show up there.
