I've confirmed with the developers that J-Link EDU devices should be supported in v3.9.3 of nRF Connect for Desktop. Can you please test and verify?

Thanks!

It says J-Link EDU on it. Version 10.1. Seems to be from July 2018. I got it from our programmers.

Hi Peter,

the current version of nRF Connect for Desktop is v3.9.3. What J-Link device are you using?

Hi again,

Are there any updates regarding the programmer in later versions of nRFConnect? I am still using rev 3.7.1...

Hello, and thanks for sharing.

There are known issues with latest version of the nRF Connect for Desktop 3.9.x and its internal apps, and using an external J-Link device to program, which we are working to solve.

Currently, the best solution is to use nrfjprog command line to program your device with latest nRF Command line tools, which now supports modem updates. Or downgrade nRF Connect for Desktop to v3.7.1 with these steps:

Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1, because 3.7.2 was not needed and not released for these).
After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
In the Settings, click on “Add source”, enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json and click “Add”.
Back in the list of all apps, all apps should show up twice now, one with “official” below them and one with “3.7 compatible apps” below them. If you want to hide the incompatible versions, click on “Filter” and deselect “Official”.
Install the apps you need in the old versions and use them.

Kind regards,
Øyvind

I can confirm this issue. We are using a custom PCB and currently can't update the modems.

This is my system report:

`nrfjprog --version` returns:

nrfjprog version: 10.12.1

Using a J-Link device for programming.

The issue does not occur when trying to flash the modem fw on my nRF9160DK (Rev. 1.0.0) using the board's debugger.

Update: Current workaround I found: It works when using the debug out port of the DK to programm our PCBs. So it seems to be an issue related to the nRF Programmer and J-Link adapter.

Also, can you please run the following command in your command prompt: nrfjprog --version

Hi Peter,

Thanks for reporting this. We are aware of some issues. I will forward this to our nRF Connect for Desktop team and get back to you within the day.

Can you please attach the system report from the application:

Thanks!

Kind regards,
