The change you have made will increase RAM usage, and I suspect that you might not actually resolving the issue, but hiding/delaying it by increasing the stack guard area.</p> <p>You should rather locate the thread that causes the stack overflow and increase its stack size.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/409430?ContentTypeID=1Sat, 11 Feb 2023 01:15:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e8351f1-4d4c-4305-a1d1-036d4afca547caidehen<p><span>I press the button twice a second, it&#39;s random sometimes I press it once and sometimes I press it a dozen times and I&#39;m not doing anything with the configuration&nbsp;&nbsp;</span></p> <p><span><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1676078043305v1.png" alt=" " /></span></p> <p><span>I doubled the parameter in the image above.
