https://devzone.nordicsemi.com/f/nordic-q-a/31021/using-printf-with-itmI would like to use printf using ITM for debugging my application using a BL652 module (nRf52832). I have followed the instructions in the Keil paper APNT_308. Printf is working fine when I execute the code on the PCA10040 board, but when I connecten-USTelligent Community 13Mon, 05 Mar 2018 20:18:08 GMThttps://devzone.nordicsemi.com/thread/122912?ContentTypeID=1Mon, 05 Mar 2018 20:18:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:109ebb38-273b-4f13-a141-0e4f4cc2d63ePer Andersen<p>Updating to Segger v 6.22f did the job, thank you.</p> <p>/Per</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/122742?ContentTypeID=1Mon, 05 Mar 2018 07:58:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:57ef85c5-d691-4afb-8e18-63541b53d6efH&#229;kon Alseth<p>Hi,</p> <p></p> <p>There was a bug in segger&#39;s firmware where it listened on the wrong SWO pin in DEBUG_OUT mode and therefore did not route the SWO signal correctly, and this was fixed in v6.22f.</p> <p>Could you try a newer Segger JLink Driver and see if this works better? Remember that when prompted to upgrade firmware, press &quot;yes&quot;.</p> <p></p> <p>I&#39;ve had issues with getting SWO print to work in Keil myself, but it normally works if I open up a JLink Commander and input &quot;swoview &lt;freq in hz&gt;&quot; (normally 4 MHz). Could you try this and see if that prints anything?</p> <p></p> <p>Cheers,</p> <p>Håkon</p><div style="clear:both;"></div>
