https://devzone.nordicsemi.com/f/nordic-q-a/6824/uvision-debugger-runs-nutsDear All, uVision debugger seems to execute code randomly. Picture shows stepping through the code. Codeline marking in grey also seems odd. I would have expected to return from function on detected GNGGA string, but somehow it also runs into GNRMCen-USTelligent Community 13Fri, 17 Jul 2015 08:51:49 GMThttps://devzone.nordicsemi.com/thread/24036?ContentTypeID=1Fri, 17 Jul 2015 08:51:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0471feba-4e85-491c-8158-6f2188dd5100Susheel Nuguru<p>Andreas, Can you please update/accept this thread.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/24035?ContentTypeID=1Thu, 30 Apr 2015 11:59:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ce5e779b-d2a6-45b7-ba9d-6afe488b1b18Susheel Nuguru<p>I think the debugger wont work efficiently with max optimisation, so you need to remove your optimisation to allow extra debugging stay in your code. Try out this thread to know how you can acheive that. <a href="https://devzone.nordicsemi.com/question/35689/watch-variables-in-keil-not-in-scope/">devzone.nordicsemi.com/.../</a></p><div style="clear:both;"></div>
