Flash, RAM and Heap Usages Calculation at Run timehttps://devzone.nordicsemi.com/f/nordic-q-a/90162/flash-ram-and-heap-usages-calculation-at-run-timeHi, 1. How to calculate the Flash and RAM usages at runtime? I am able to do it static way but wanted to analyze this at runtime. 2. How to calculate the Heap usages at runtime? I have gone through some documents those referring to &quot;size_t sys_heap_usable_sizeen-USTelligent Community 13Thu, 04 Aug 2022 12:25:11 GMTRE: Flash, RAM and Heap Usages Calculation at Run timehttps://devzone.nordicsemi.com/thread/380118?ContentTypeID=1Thu, 04 Aug 2022 12:25:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1da500a-ae5e-4f8f-863c-51a2bf441cf3Susheel Nuguru<p>I do not think there are any native tools that will aid you to profile/monitor memory at runtime. But you can probably profile the activity using <a href="https://percepio.com/tz/tracealyzer-for-zephyr/getting-started-with-tracealyzer-for-zephyr-rtos/">traceanalyzer </a>or <a href="https://www.zephyrproject.org/tracing-zephyr-applications-with-segger-systemview/">systemviewer</a>.</p> <p>If you are hunting memory overflows then <a href="https://docs.zephyrproject.org/3.0.0/reference/kconfig/CONFIG_STACK_SENTINEL.html">CONFIG_STACK_SENTINEL </a>is a nice tool to enable..</p><div style="clear:both;"></div>RE: Flash, RAM and Heap Usages Calculation at Run timehttps://devzone.nordicsemi.com/thread/380022?ContentTypeID=1Thu, 04 Aug 2022 05:32:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5ca9b5ba-ee3e-43c0-a110-4cc6ba9848e9vim_nordic<p>Hi Susheel,&nbsp;</p> <p>As you have mentioned that in&nbsp; nRF5 SDK module, flash runtime check is not possible but we are using the nCS connect SDK. <strong>Is this possible in nCS&nbsp;Connect SDK v1.9.1</strong>?</p><div style="clear:both;"></div>RE: Flash, RAM and Heap Usages Calculation at Run timehttps://devzone.nordicsemi.com/thread/377846?ContentTypeID=1Wed, 20 Jul 2022 11:52:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0913ba2b-06be-4dcf-b023-acba0e3d65f8Susheel Nuguru<p>This is not possible to do only using nRF5 SDK modules.
