https://devzone.nordicsemi.com/f/nordic-q-a/9924/debugging-nrf52-with-printfHello, I am new to working with nrf52 and was looking for a way to make printf work in a blank project that I have created. I followed the uart example for the peripheral and my main function currently looks like: int main(void) { uint32_t err_code;en-USTelligent Community 13Thu, 26 Jan 2017 23:49:24 GMThttps://devzone.nordicsemi.com/thread/36818?ContentTypeID=1Thu, 26 Jan 2017 23:49:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dcbfa3ef-b018-4680-a8f0-cbf8cba85bbaTong Yu<p>Did you check the config.h in &quot;config&quot; folder? You probably need to enable UART in that file.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36817?ContentTypeID=1Sat, 07 Nov 2015 00:19:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d95d5825-1e3e-4c04-b0e5-b3edb526e496aep<p>Looks like you forgot SOFTDEVICE_HANDLER_INIT? before that APP_UART_FIFO_INIT won&#39;t work. Just debugged that myself...</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36821?ContentTypeID=1Tue, 27 Oct 2015 16:40:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:54e1bb31-ed65-4050-8580-f92655665015Abhi<p>I have followed that tutorial and have it setup, thank you very much. Just out of curiosity do you have any idea why the regular printf() that I was following did not work?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36816?ContentTypeID=1Tue, 27 Oct 2015 07:13:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e76e3cb8-2122-458b-8a40-7e17a59e0d24Susheel Nuguru<p>shouldn&#39;t it be similar to nRF51 printf requirement? have you included retarget.c file in your project as printf needs few standard functions to be overridden.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36820?ContentTypeID=1Mon, 26 Oct 2015 23:53:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3b8459b6-2aba-4cbf-bbae-ac6af634c58dpltv<p>I have used Segger RTT with great impact. A very useful tool. The only issue ofcourse is memory foot print.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36819?ContentTypeID=1Mon, 26 Oct 2015 23:36:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aab7371b-b01e-469b-84f6-cfbe05561834Bill Siever<p>If you just need <code>printf()</code> style debugging and are using JLink (which is used on the Nordic Developer boards), you might want to try Segger&#39;s Real-Time-Terminal.
