https://devzone.nordicsemi.com/f/nordic-q-a/124547/how-to-change-start-address-of-app-in-ncs-nrf54I want to change the start address of the app in the ESB example from nCS 3.0.2. By default, after compiling and flashing, the program runs from address 0x0. I want to change it to, for example, 0x10000. I tried defining CONFIG_FLASH_LOAD_OFFSET=0x10000en-USTelligent Community 13Tue, 23 Sep 2025 13:14:00 GMThttps://devzone.nordicsemi.com/thread/549572?ContentTypeID=1Tue, 23 Sep 2025 13:14:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b45dc9e-8fbd-4d83-b7ba-a0d779127edaEinar Thorsrud<p>Hi,</p> <p>This looks mostly good, except for pm_static.yml. Try&nbsp;defining what the first region is (in this example it is called nrf5_mbr for historical reasons, but it does not matter). Like this:</p> <p><pre class="ui-code" data-mode="text">app: address: 0x10000 region: flash_primary nrf5_mbr: address: 0x0 end_address: 0x10000 placement: after: - start region: flash_primary size: 0x10000</pre></p> <p>Testing on my end when also adding <code>CONFIG_FLASH_LOAD_OFFSET=0x10000</code> in prj.conf, I see that the app is placed at&nbsp;<span>0x10000. (Of course, with nothing placed at address 0 this application will never run, so you will need a bootlaoder or something else at address 0 in addition).</span></p><div style="clear:both;"></div>
