https://devzone.nordicsemi.com/f/nordic-q-a/23320/is-it-impossible-to-debug-a-ble-project-used-softdevice-with-eclipseWhen I used keil, I set breakpoints to debug ble project used softdevice. And it was useful.. And now I&#39;m using eclipse and gcc. It works well at first, but when step debugging, an error occurs in a function related to the softdevice, calling sd_xxxen-USTelligent Community 13Sat, 08 Jul 2017 08:09:41 GMThttps://devzone.nordicsemi.com/thread/91681?ContentTypeID=1Sat, 08 Jul 2017 08:09:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a9e356b9-b538-4f72-be45-e6131ac234f8J.Kwon<p>Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91682?ContentTypeID=1Fri, 07 Jul 2017 08:08:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd8a1683-b204-4c29-a312-9a2d9caa5bddNguyen Hoan Hoang<p>You can set the breakpoints before start but don&#39;t expect to do single stepping afterwards. Stepping may work in case when you are stepping within the same function where the breakpoint is. The moment you step out of the function, it will surely crash.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91680?ContentTypeID=1Fri, 07 Jul 2017 07:27:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4dbcccbe-37ee-4f56-8e59-448933bfb1c5endnode<p>Indeed it&#39;s impossible to debug Soft Device for which your Eclipse has no information. It is possible to debug your code but any time-critical operation done in the stack will be killed by your debugger so typically nothing radio-related will work as you expect. That&#39;s why we all here speak about RTT and UART debugging logs all the time, that&#39;s how such embedded system is typically debugged...</p><div style="clear:both;"></div>
