If the sysbuild or mcuboot enabled (Partition Manager enabled) the partition definitions in your DTS are ignored, and the Partition Manager&#39;s configuration takes precedence. Then during runtime your application expects partition defined in the DTS, but this is not present at runtime which leads to the issue you mentioned.</p> <p>You can use<span>&nbsp;&#39;no sysbuild&#39; in the command (<a href="https://devzone.nordicsemi.com/f/nordic-q-a/117222/dt_n_nodelabel_settings_storage_reg_idx_0_val_size-undeclared" rel="noopener noreferrer" target="_blank">DT_N_NODELABEL_settings_storage_REG_IDX_0_VAL_SIZE&#39; undeclared</a>)</span></p> <p><span><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1761209644016v1.png" alt=" " /></span></p> <p>or define your partition in pm_static.yml.&nbsp;</p> <p>I can check your build folder both for DK and custom board. Can you please share these with me?</p> <p>Regarding the devicetree editor query, there is no specific setting in the Devicetree Visual Editor to enable the internal flash page.&nbsp;</p><div style="clear:both;"></div>
