No matching trait found

[Pema]

Hi,

I am using Win10, nRF Connect 3.9.0, programmer 2.0.0. and I get "no matching trait found" when trying to program the 9160 on my board. I have seen a few other questions regarding this and wanted to confirm that the problem exist not only for Thingy91, but also for a custom board.

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:

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.

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:

1. 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).
2. After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
3. 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”.
4. 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”.
5. Install the apps you need in the old versions and use them.

Kind regards,
Øyvind

Hi again,

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

Hi Peter, 

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

-Øyvind

[Pema]

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

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!
