https://devzone.nordicsemi.com/f/nordic-q-a/21622/nrf52-and-keil-debug-printf-viewerHello, I followed the instructions of KEIL in www.keil.com/.../ulink2_trace_itm_viewer.htm However, I cant get any outputs in Keil Debug(Printf) Viewer using printf or ITM_SendChar. Any Ideas ?

See here: <a href="https://devzone.nordicsemi.com/blogs/909/debugging-nrf52-series-devices-using-trace/">devzone.nordicsemi.com/.../</a></p> <p>Another route is to just install the uart driver and route printf through the virtual uart port on segger. Then you can pick up printf when you aren&#39;t in debug with any terminal emulator. This makes the run environment more normal than in the debugger.</p><div style="clear:both;"></div>
