https://devzone.nordicsemi.com/f/nordic-q-a/30273/soft-device-with-mbed-os-memory-map-for-nrf52840Hi, I am working on my production hardware with nRF52840 on it. I am using MBED OS. What should be the memory map of 52840 for soft device and Application code? I am using Keil uvision so what are correct IROM1 and IRAM1 addresses?en-USTelligent Community 13Thu, 08 Feb 2018 14:48:50 GMThttps://devzone.nordicsemi.com/thread/120305?ContentTypeID=1Thu, 08 Feb 2018 14:48:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fffad583-8030-470a-a9d6-102bb0b18ff7MartinBL<p>It depends on what Softdevice version you are using. The application&#39;s IROM1 and IRAM1 start addresses should match the&nbsp;Softdevice&#39;s&nbsp;flash and RAM requirements&nbsp;which&nbsp;are documented in the Softdevice release notes:</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-85503f231ab44fba98e5b3fe759eb529/pastedimage1518100997215v2.png" alt=" " /></p> <p>Note that the&nbsp;release notes states the <em>minimum</em> RAM size. The actual requirement depends on your application&#39;s Softdevice configuration. If you use the examples in our SDK the RAM settings will be printed out to your serial terminal when you call&nbsp;nrf_sdh_ble_enable().&nbsp;</p><div style="clear:both;"></div>
