https://devzone.nordicsemi.com/f/nordic-q-a/83402/ncs1-8-0-52840-mcuboot-spi-external-flash-can-t-build-passHello When I use ncs1.7.1 52840 + mcuboot + spi + external flash it works well, but when I update ncs to 1.8.0 I can&#39;t build it. I also add CONFIG_MULTITHREADING =y in my project. Can you give me some advice thanks.en-USTelligent Community 13Fri, 07 Jan 2022 01:19:21 GMThttps://devzone.nordicsemi.com/thread/346575?ContentTypeID=1Fri, 07 Jan 2022 01:19:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:38427db6-edca-4296-8d80-b145c827122dАвгуст<p>Thanks you, It works.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/346525?ContentTypeID=1Thu, 06 Jan 2022 14:53:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d510a045-ecae-4a4a-b73c-7ef759df617cH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>Are you using the sample from this thread?</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/82430/ncs-external-flash-ota-change-qspi-to-spi">https://devzone.nordicsemi.com/f/nordic-q-a/82430/ncs-external-flash-ota-change-qspi-to-spi</a></p> <p>&nbsp;</p> <p>If yes, then try placing this file:</p> <p>hello_world_spi_nor_ext_flash/child_image/mcuboot/nrf52840dk_nrf52840.overlay</p> <p>To be in a &quot;boards&quot; catalog:</p> <p><span>hello_world_spi_nor_ext_flash/child_image/mcuboot/boards/nrf52840dk_nrf52840.overlay</span></p> <p><span>&nbsp;</span></p> <p><span>Could you see if this then works at your end?</span></p> <p><span>&nbsp;</span></p> <p><span>Kind regards,</span></p> <p><span>Håkon</span></p><div style="clear:both;"></div>
