https://devzone.nordicsemi.com/f/nordic-q-a/72498/mcuboot-build-issueDear Concern, I am getting MCUboot build errors as shown in the below. C:\Nordic\v1.5.0&gt;west build -b nrf5340dk_nrf5340_cpuapp -d build_mcuboot bootloader/mcuboot/boot/zephyr [4/142] Building C object CMakeFiles/app.dir/C_/Nordic/v1.5.0/bootloaderen-USTelligent Community 13Mon, 08 Mar 2021 13:06:47 GMThttps://devzone.nordicsemi.com/thread/298378?ContentTypeID=1Mon, 08 Mar 2021 13:06:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c2c43f55-7f7d-4ec7-b224-c4eda68756ccVidar Berg<p>Hi Srinivas,</p> <p>MCUboot is usually built as a part of a <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_multi_image.html">Multi-image build</a>. This happens automatically after you add the CONFIG_BOOTLOADER_MCUBOOT=y setting to your project configuration. Also, if needed, you can include overlay configurations for the mcuboot build in your project directory by creating the &#39;child_image&#39; directory like the asset_tracker_v2 application does in v1.5.0\nrf\applications\asset_tracker_v2. E.g. \child_image\mcuboot.conf\, where mcuboot.conf is the overlay file you want to apply to the MCUboot &quot;subimage&quot;.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
