We currently use MCUboot + SPM for bootstrapping and DFU Image Manager for applying firmware updates. If I enable CONFIG_BUILD_WITH_TFM and CONFIG_BOOTLOADER_MCUBOOTen-USTelligent Community 13Wed, 10 Mar 2021 17:58:31 GMThttps://devzone.nordicsemi.com/thread/299109?ContentTypeID=1Wed, 10 Mar 2021 17:58:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:85e39dee-df70-45f0-8c99-bc4826373e34caspar.friedrich<p>That&#39;s my understanding, too. Currently we use the API provides through&nbsp;<span><span style="font-family:&#39;courier new&#39;, courier;">dfu/mcuboot.h</span> to install firmware updates and verify images.
