Hi Andreas,

Thank you very much.
It worked this time. I think the problem was the cable! Tried a different one and it was ok.

Regards,

Hi Alan.

Looks like the issue is that your computer can't detect your board.

Can you try this:

1. Make sure that no other DK's are connected to your computer and that no other SW is reserving J-Link.

2. Make sure that you have the latest J-Link downloaded.

3. Make sure that the USB cable you use to the DK is not broken in any way.

4. Download and unzip the latest modem firmware, and enter the unzipped folder.

5. Make sure that you are running Python 3 and check that you have the latest installed pip version (python -m pip install --upgrade pip).

6. Make sure that you are running the latest nrfutil version (pip install nrfutil).

7. Try to install the upgrade firmware tool again, by unzipping the nrf9160_mdm_dfu.zip folder, enter it and run pip install nrf9160_mdm_dfu-0.10.1+dev-py3-none-any.whl

8. Go back to the mfwnrf916007029alpha folder and run nrf9160_mdm_dfu --update

If this does not work, are you able to program the board from Segger Embedded Studio? What does nrfjprog -i returns when you run it in CMD?

Best regards,

Andreas
