https://devzone.nordicsemi.com/f/nordic-q-a/48148/increase-bootloader-secure-dfu-size-sdk-15-3I changed the bootloader size by changing the flash start address (in the .icf file, from 0xf8000, to 0xf7000). I just want to check what other files/settings needs to be changed in order for this to work (with SoftDevice and application)?

You don&#39;t need to change anything else.&nbsp;&nbsp;</span></p><div style="clear:both;"></div>
