https://devzone.nordicsemi.com/f/nordic-q-a/55689/what-is-the-ram-modelHello, I am evaluating the nRF52840-DK. I just want to play around with Nordic for awhile to determine if I want to port my current project which is written in C++ for Teensy. I built one of the example apps in Segger and noticed this report on RAMen-USTelligent Community 13Tue, 17 Dec 2019 13:18:56 GMThttps://devzone.nordicsemi.com/thread/225894?ContentTypeID=1Tue, 17 Dec 2019 13:18:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7470adb9-4ee2-450e-9b13-292798df5b24H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>&nbsp;</p> [quote user=""]Is this just like the Teensy model where the first segment of green corresponds to the amount of static Heap usage and the second green segment corresponds to the minimum Stack usage?[/quote] <p>&nbsp;That is the stack section absolute address location and size. .heap is not used here, but the stack is placed at the top of RAM, and grows down. If you check out the generated .map file, you can search for the symbol &quot;__StackTop&quot; to see exactly this.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
