without effect

Jlink less than or equal to V9.20, can't be used?

The serial number looks not to be a Nordic DK, what SEGGER j-link are you using here? Is it genuine?

Best regards,

Looks like it did not like the set SWD speed.

Try a slower SWD clock frequency:

nrfjprog.exe --clockspeed 250 --family NRF52 --eraseall --log

log.log show the key line:

2020-Apr-28 18:26:26 . . . . Segger_connect_to_emu_without_snr: JLinkARM.dll reported "-1", an unknown error.

nrfjprog version: 10.8.0
JLinkARM.dll version: 6.70d

You can also see it clearly from the first picture(MDK) above.

If you write nrfjprog --version what does it output?

What programmer are you using?

Best regards,
