https://devzone.nordicsemi.com/f/nordic-q-a/81768/ncs-52-serial-bootloader-updateHello In my another ticket https://devzone.nordicsemi.com/f/nordic-q-a/81555/ncs-upgradable-bootloader . I know there is currently no support for upgrading the bootloader ( MCUboot ) on nRF52 Series devices. I want to know if you plan to supporten-USTelligent Community 13Wed, 17 Nov 2021 13:00:50 GMThttps://devzone.nordicsemi.com/thread/339431?ContentTypeID=1Wed, 17 Nov 2021 13:00:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:436f27e9-0eec-4981-a380-e0b80d85a781ovrebekk<p>Hi&nbsp;</p> <p>There are no current plans to allow MCUboot to be updated on the nRF52 series, no.&nbsp;</p> <p>A critical difference when using the bootloader architecture in NCS is that the bootloader is essentially split in two. You have MCUboot which only validates the image, and copies a new image from slot 1 to slot 0, while everything else (like transferring new images over Bluetooth or some&nbsp;other transport) is handled elsewhere.&nbsp;</p> <p>This makes it less important to be able to update MCUboot, compared to being able to update the bootloader in the nRF5 architecture, since you can still update all the higher level bootloader functionality that is handled outside MCUboot.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
