https://devzone.nordicsemi.com/f/nordic-q-a/16801/can-a-dfu-of-softdevice-plus-uploader-from-sd132v2-to-sd132v3Hi, I have been trying to do it and even though I have generated packages using the old nrfutil and the new 1.5, when I use nRF connect to do the upload it aborts without a reason. I am using --debug since the original firmware is with v2.0, anden-USTelligent Community 13Mon, 03 Oct 2016 13:41:50 GMThttps://devzone.nordicsemi.com/thread/64289?ContentTypeID=1Mon, 03 Oct 2016 13:41:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:558f0870-a28a-41e0-b3c2-c51d4ab371c9bjorn-spockeli<p>The Secure DFU bootloader is considerably(~23 kB) larger than the legacy bootloader (~13kB). The legacy bootloader only allocates 16kB and if you have not increased the size to 24kb, then you will not ba able to update to the new secure booloader.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/64287?ContentTypeID=1Mon, 03 Oct 2016 13:17:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6845e26c-4585-4c8a-acd1-f54c70286699Antonio<p>Yes.
