https://devzone.nordicsemi.com/f/nordic-q-a/36445/dfu-application-address-can-exceed-0x000e0000-open-bootloaderHi, I am confused about the ROM layout, would you please correct me? Thanks. Based on my understanding, for open bootloader scenario(like nrf52840 dongle), the bootloader locates at 0x000E0000~0x000FE000. MBR locates 0x00000000~0x00001000.

This is not an issue if the application is not exceptional big.&nbsp;But you are right, we should have made it more clear about the size of the application if bootloader is used.&nbsp;</p><div style="clear:both;"></div>
