https://devzone.nordicsemi.com/f/nordic-q-a/71224/unable-to-inspect-local-variables-in-ses-5-34aHi, I&#39;m running SES 5.34a on a Mac and building a Zephyr bluetooth sample for the nRF5340 DK. NCS version is 1.4.2. When I breakpoint in a bluetooth stack callback I cannot inspect some local (stack) variables. The project is in .../ncs/zephyr/samplesen-USTelligent Community 13Wed, 03 Feb 2021 13:51:43 GMThttps://devzone.nordicsemi.com/thread/292703?ContentTypeID=1Wed, 03 Feb 2021 13:51:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a670675a-6c09-480f-a7ac-546f4aca6273Einar Thorsrud<p>Hi,</p> <p>Thanks for letting us know the issue was with optimization. That makes sense. Regarding the follow up question I see you have posted a separate question for it <a href="https://devzone.nordicsemi.com/f/nordic-q-a/71059/how-to-set-optimisation-level-in-ses-5-34a-nordic-version">here</a>, so I suggest you continue there.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/292548?ContentTypeID=1Tue, 02 Feb 2021 16:31:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:af38a719-7a84-42c0-8e8d-2cd9f659282eskajam66<p>It looks like the problem was the optimisation setting in prj.conf.&nbsp; It should have been a lowercase &quot;y&quot; not &quot;Y&quot;.</p> <p>However, changing it to:</p> <p><pre class="ui-code" data-mode="text">#CONFIG_DEBUG_OPTIMIZATIONS=y CONFIG_NO_OPTIMIZATIONS=y</pre></p> <p>causes a stack overflow on cpu0 which I guess is the network core.</p> <p>So, a follow-on question - how do I control the optimisation level of the application only? Alternatively, if it is not possible to control the optimisation per cpu, how do I increase the stack for cpu0?</p><div style="clear:both;"></div>
