I added the setting CONFIG_SPI_NOR_SFDP_DEVICETREE=y per the directions in the Dev Academy lesson on Exercise 3 – DFU with external flashen-USTelligent Community 13Tue, 01 Jul 2025 13:39:43 GMTRE: MCU Boot with sysbuild with SPI external flashhttps://devzone.nordicsemi.com/thread/541051?ContentTypeID=1Tue, 01 Jul 2025 13:39:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ce21a41a-a69c-4904-8018-936b5fc34310Kenneth<p>Hi,</p> <p>Can you check out&nbsp;\zephyr\drivers\flash\Kconfig.nor and in specific:</p> <p><pre class="ui-code" data-mode="text">config SPI_NOR_SFDP_DEVICETREE bool &quot;Basic Flash Parameters from devicetree node&quot; help The JESD216 Basic Flash Parameters table must be provided in the sfdp-bfp property in devicetree.
