Have you solved this problem？ I have checked nordic office doc some days,and no ideas.

Same issue here.

I suspect there might be some secure boot issue. I tried adding --sd-boot-validation=NO_VALIDATION and --app-boot-validation=NO_VALIDATION to the nrfutil call - which did not resolve the issue.
Also after having a look at the memory map for nRF52840 at https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Flib_secure_boot.html&cp=7_1_3_5_0_8 - I changed layout.ld so that both rom and prog were inside the application area (0x0002 7000 - 0x000F 8000 (836 kB)). After that change I was still able to flash but this time the Dongle did not show up at all as a USB device. To reenter DFU mode I now need to push the reset button. So it seems that DFU mode is left but the Application is not started correctly.

Now I'm a bit lost. I suspect that the softdevice "partition" is now corrupt. Any suggestions as to what I could try next? I guess I need to download the SDK and reflash a softdevice firmware.

One open question remains on my side. Is there a way to know which bootloader version is currently flashed? I would like to try to generate bootloader settings which disable boot validation - but for that I need to know what parameter to give for --bl-settings-version.

This bug should have been solved after June 10.

./deploy.py --board=nrf52840_dongle_dfu --opensk --programmer=nordicdfu

is enough now.
