https://devzone.nordicsemi.com/f/nordic-q-a/5468/iot-0-7-0-code-ram-stack-requirementsI can&#39;t find in the documentation for the IoT the usual section about requirements for the start of user code, the start of user RAM, the max stack used and whether any heap is required. Those are usually in the softdevice spec, but there isn&#39;t one foren-USTelligent Community 13Tue, 10 Feb 2015 01:24:28 GMThttps://devzone.nordicsemi.com/thread/19085?ContentTypeID=1Tue, 10 Feb 2015 01:24:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:376e4cd1-017c-4034-878a-31f128f3c0f1RK<p>Perfect - thanks - I&#39;ve updated RKNRFGO&#39;s softdevice info list with that so it&#39;s recognised for programming.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19084?ContentTypeID=1Mon, 09 Feb 2015 14:57:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:752b24c4-539d-44f3-af09-7507032e18fePetter Myhre<p>Your Flash and RAM sizes are correct.</p> <p>The call stack and heap size have not been tested, but they are assumed to be similar to S110, 1536 bytes for call stack, and 0 bytes for heap size.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19083?ContentTypeID=1Mon, 09 Feb 2015 08:57:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c15601d3-e5b8-4ea2-8b2c-32481bb5463cRK<p><a href="https://devzone.nordicsemi.com/question/28548/iot-sdk-nrf-51822/">devzone.nordicsemi.com/.../</a></p> <p>That one says 96K flash and 8K RAM, which I take to mean user code can/does start at 0x18000 and user ram at 0x20002000. Can&#39;t find mention of stack anywhere and I&#39;ve never seen any nordic softdevice which uses heap, but the softdevices specs always confirm that.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19082?ContentTypeID=1Mon, 09 Feb 2015 08:52:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa38f4d4-14bc-4352-9461-e4004df4a43cPetter Myhre<p>Can you please include links to the questions/answers you are referring to?</p><div style="clear:both;"></div>
