Yes, after that I can see DfuTarg running.

Thank You

My output is:

$ nrfjprog --memrd 0xff8
0x00000FF8: 00072000 |. ..|

So it seams ok.

Your hex file runs fine on my DK. Maybe the BL start address is not set. Try to read out the bootloader start address which is stored inside the MBR:

> nrfjprog --memrd 0xff8 // should return 0x72000

Edit: both flash targets are using the --sectorease option. This will cause the start address to be erased when you run both. Try make flash_softdevice && make flash the configuration below.

# Flash the program
flash: default
	@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa_s132.hex
	nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa_s132.hex 
	nrfjprog -f nrf52 --reset

# Flash softdevice
flash_softdevice:
	@echo Flashing: s132_nrf52_6.1.1_softdevice.hex
	nrfjprog -f nrf52 --program $(SDK_ROOT)/components/softdevice/s132/hex/s132_nrf52_6.1.1_softdevice.hex --chiperase
	nrfjprog -f nrf52 --reset

Yes, I have done that as well

And before any building I've followed instruction regarding keys generation from here: devzone.nordicsemi.com/.../getting-started-with-nordics-secure-dfu-bootloader

Hi,

Did you remember to flash the Softdevice as well? You can use the flash_softdevice target for that: make flash_softdevice && make flash. The pre-compiled hex files have been merged with the Softdevice.
