Updating modem firmware on nRF9160 DK fails (NRFJPROG DDL: -13 NO_EMULATOR_CONNECTED)

[f0corner]

I'm trying to update the modem firmware on my new nRF9160 DK using nrf9160_mdm_dfu --update, but I get the following error: pynrfjprog.API.APIError: An error was reported by NRFJPROG DLL: -13 NO_EMULATOR_CONNECTED.

The error suggests that the CLI is not able to detect the SNR. However, I do see the JLINK drive in my Finder (I'm on macOS). And I am also seeing the following three serial ports:

• /dev/cu.usbmodem000960079309
• /dev/cu.usbmodem10
• /dev/cu.usbmodem11

Hi,

 

Q1: Could you ensure that SW5 is set in the "nrf91" position?

Q2: Have you tried using different usb cables?

Q3: Are you able to successfully read the flash via nrfjprog? "nrfjprog --memrd 0 --n 1024 -f nrf91"

Q4: Do you have the latest version of nrfjprog/pynrfjprog installed?

Kind regards,

Håkon

Hello Håkon,

Thank you for your quick response!

As you probably had guessed, I was not running the latest version of nrfjprog. Besides updating nrfjprog to version 9.8.1, I also had to update JLinkARM.dll from 6.20h to 6.40h.

Thank you very much for your help. Have a great day! A+
