I've seen several questions on this forum on issues with setting up the NRF LOG, however, I am still having many issues and I can't seem to get UART logging working.
I am using the BL653 Dev Kit, which contains the nRF52833 chip. Here are the main files for the sample project I am trying to configure:
main:c
#include <stdbool.h>
#include <stdint.h>
#include "nrf.h"
#include "nordic_common.h"
#include "boards.h"
#include "nrf_delay.h"
#include "nrf_log.h"
#include "nrf_log_ctrl.h"
#include "nrf_log_default_backends.h"
/**
* @brief Function for application main entry.
*/
int main(void)
{
APP_ERROR_CHECK(NRF_LOG_INIT(NULL));
NRF_LOG_DEFAULT_BACKENDS_INIT();
NRF_LOG_INFO("This is a test log.");
uint32_t count = 0;
while (true)
{
NRF_LOG_INFO("Counter Value: %d", count);
nrf_delay_ms(500);
count++;
}
}

I am using PuTTy attached to the "JLINK CDC UART Port" that enumerates on the machine when plugging into the "Atmel USB" port on the dev kit. The defined baud rate is 115,200.
I have also tried defining NRF_LOG_USES_RAW_UART to 1, but no luck.
Do anyone have idea what I might be missing here?
