Have you updated the memory layout in both projects to match your device?

Hi,

Please take a look at the most recent replies in this thread here: https://devzone.nordicsemi.com/f/nordic-q-a/63362/secure-buttonless-dfu-problem-on-nrf52832-soft-device-112 where I uploaded a nRF52832 app with the DFU buttonless mechanism and a 52832 bootloader that works with s112 Softdevice. It's based on SDK 16.0.0 but there should only be minor differences if you use SDK 17.0.0
