Can operate RTT logs on Zephyr based project

[alonmat]

I am trying to use RTT logs for debuging. I have no UART in my board. so, this is my ony option for debuing.

I tried it on my board and the nrf52dk/nrf52832 board.

I take the example from \zephyr\samples\basic\blinky and I am trying to follow the instructions

in DevAcadamey (such as Logger module) or many other sources to operate and see the RTT logs but I failed in all of them.

Can you send me step by step instructions how to change the basic blinky example (or another example)

in a way that RTT logs will work.

By the way, in my previous projects in nrf connect without zephyr I use the RTT without any problem by changing the sdk_config.h

#define NRF_LOG_BACKEND_RTT_ENABLED 1

in main.c,

add

#include <zephyr/logging/log.h>

add

#define LOG_MODULE_NAME blinky

LOG_MODULE_REGISTER(LOG_MODULE_NAME);

add

LOG_INF("Bluetooth initialized");

in prj.conf

add

# Config logger

CONFIG_LOG=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_LOG_BACKEND_RTT=y

CONFIG_LOG_BACKEND_UART=n

CONFIG_LOG_PRINTK=n

then show message in RTT

Thanks.  Working .

I also had to look at the right terminal window:

1) Click the connected devices --> RTT --> Electric Icon

2) then a new popup search window is openned in the top of VS-code

3) then click the device ID.

4) RTT window is openned 

I missed the top popup window....
