Can't connect a device after updating nrf connect for vs code extentions version 2024.12.55.

[Martin73]

Hello,

I'm using 'nRF Connect for Desktop v4.2.0' and 'nRF Connect SDK v2.3.0' on windows 11.

I was using vs code well for developing nrf52840 board.

But, I found it cat not connect a device today. And I checked what is different between today and a feww days ago.

Diffrence is that 'nrf connect for vs code extentions version 2024.12.55'.

So, I tried to solve thsi issue and I could find "nrf-connect.deviceProvider" in settings of nRF Connect for VS Code extension.

I was tried to downgrade that extension version but the result is same... 

 

I think this is almost same with 'Case ID: 335923' but I'm working on windows11 so I couldn't use 'apt-get install...'.

Could you tell me how to solve this issue?

Thank you.

Hello,

We are transitioning away from nrfjprog (nRF Command Line Tools) over to nrfutil. If you are using a new NCS version, this will be automatically added to the toolchain, but if you are using an old version of NCS (a version before nrfutil was used as a standard), you may see issues like this.

Therefore, try installing nrfutil on your computer (outside any SDK environment). You can find it here:

https://www.nordicsemi.com/Products/Development-tools/nRF-Util

After installing it, please run a couple of commands:

1: "nrfutil self-upgrade"

2: "nrfutil install device"

3: "nrfutil upgrade device"

This will make sure that:

1: You are using the latest version of nrfutil.

2: You have installed the "device" submodule

3: You have the latest version of the "device" submodule installed.

The "device" submodule is what replaces the functionality of nrfjprog. 

Try this, and let me know if it doesn't work. You may need to properly close and re-start VS Code after completing steps 1-3.

Best regards,

Edvin

I'm having the same issue.

I've followed your instructions and set the Nrf-connect>Nrfutil: Home property and restarted VSCode.  Still No Devices Found.  This abruptly quit working so I uninstalled everything and upgraded.

SDK 2.8.0

Toolchain 2.8.0

VSCode 1.96.4

Any ideas?

Hello Jim,

Please make sure that (the new) nrfutil is installed, and is available via command line interface. So after installing it, open a command line, and type:

nrfutil --version

And check that it prints the version that you have. If it doesn't print the version, make sure nrfutil is in your computer's environment path. (let me know if this isn't working)

Also make sure that you have installed the submodule "device" by running the command:

nrfutil install device

After this, you can run the command:

nrfutil device list

And see if it prints some info about the connected device(s). If it does, this is the info that nRF Connect for VS Code uses to show you the connnected devices. If this command prints your device info, try restarting Visual Studio Code, and see if it now shows. If not, let me know which of the steps above that doesn't behave as described.

Best regards,

Edvin

The device I'm using is an nRF52840 Dongle.  This all work previously but stopped working.

Detected SEGGER J-Link version: JLink_V8.12c

The device command version you are currently using was tested with a different J-Link version (JLink_V8.10f) than the one you have installed (JLink_V8.12c). The tested version is not required, and your J-Link version will most likely work fine. If you get issues related to J-Link with your devices, use the tested version.

I downgraded J-Link to 8.10f and the warning went away but "nrfutil device list" still crashed.

Follow up:

I have the dongle plugged into a usb hub.  When I unplugged the other devices from the hub I got this from nrfutil device list:

$ nrfutil device list
285A4D1B8834E6F5
product USB-DEV
ports COM11, vcom: 0
COM14, vcom: 1
traits serialPorts, usb

Found 1 supported device(s)

VS Code still reports No devices found.

I also tried it directly plugged into the computer.
