Mr Leo,

Can you please check the data connection to the board. There are a few items you should check. When you plug in the nRF9160DK if you have the Jlink drivers installed (it looks like they are based on the reply) then you should see the Jlink Drive show up.

You should also see in the device manager the 3 instances of the Jlink CDC UART port's.

The nrfjprog --version only returns to version of the nrfjprog tool and the jlink Driver version. It does not read the external board.

If you execute nrfjprog -i and you get an error and the green LED indicates power to the board closer to the USB cable then I would get a new USB micro cable with data and try again.

Here is the response of the command without a board connected.

>nrfjprog -i

When you have the data cable connected you should see the Jlink Serial # as it appears on the back side of the nRF9160DK. (see image)

With the data cable connected and I verified I see the Jlink CDC UART's and Jlink drive I issued the following command and the board returned this reply.

C:\Users\djany>nrfjprog -i

960062137

I then entered the following command and received the following response.

>nrfjprog --recover
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.

I hope this helps with an answer for your customer.

Regards,

Don
