Thanks for all advises. I figured it out.

I haven't messed with my 54l devkit yet so I just tried the below code with your config and was able to see the logging messages on the "Debug In / Trace" header on the DK. Make sure you aren't using "Debug Out".

#include <zephyr/kernel.h>
#include <zephyr/logging/log.h>

LOG_MODULE_REGISTER(main, LOG_LEVEL_INF);

int main(void)
{
        for (;;)
        {
                LOG_INF("Hello World! %s", CONFIG_BOARD);
                k_sleep(K_SECONDS(1));
        }
        return 0;
}

Also, I usually have to connect on RTT again after each programming. It didn't used to be that way but it is now on my system.

It seems like all your config is there so it should be working.

Try doing that log message in a loop with a one second delay each loop. You would have to get lucky to connect via RTT fast enough after programming to see that first log message.
