Segger J-Link Plus not listed in VS Code connected devices

[abhiash4nRF]

Hello Experts,

On my Windows 10 PC, I have installed nRF for Desktop v5.0.2 and J-Link Pack version 7.94e got installed along with it.

Also installed Nordic command line tools using " nrf-command-line-tools-10.24.2-x64 ".

In VS code have installed and enabled all nRF extensions however the J-Link Plus connected never appears in Connected Devices for a nRF5340 custom board.

Also the Welcome and Applications Screen never appears as shown in the screen snap below.

Tried different versions of J-Link package however no progress. 

I am using ncs v2.6.0 and VS code v1.92.1

Also uninstalled and installed VS Code, Tool Chain, a couple of times however no effect 

 PS: previously with the same hardware I had no such issues. Something has changed.

Kindly guide me towards the solution

Thanks,

AbhiAsh

Hi Abhishek,

Do you open VSCode directly, or via the Toolchain Manager? While opening via the Toolchain manager too, do you face this issue? 
Also, as mentioned by @jorg fischer, your debug adapter might also need a firmware update.

Regards,

Priyanka

1. On my PC I installed the J-Link Package v7.98 release
Then using J-Link configurator I updated the J-Link Plus to latest firmware available
Product = J-Link PLUS V12.00
HostFW = 2024 Jul 3 16:56
EmuFW = 2024 Jul 3 16:56

2. When I launch the VScode directly then still it does not show J-link in connected devices
   Then I also launched it using nRF for Desktop > Tool Chain Manager v1.5.1 .... same behaviour

3. Then I used the J-Link Commander i.e. Jlink. With this it connects to the target

That looks strange. It should ideally appear in the output window:

If this also doesn't work, could you try uninstalling the extension, SDK, nRF Connect for Desktop application and re-installing them? 

Apologies for the trouble, but sometimes some problems during download or installations can cause strange activity after installation.

Hi there,

I don't think this is the correct device... Try picking a different device.

Hi,

I have uninstalled VScode, RF commandline tools, nRF for Desktop, ncs folder removed.

When I tried to install using nRFconnect for Desktop, the behaviour is still the same and issue not resolved

Then I tried to install according to the video on nordic website to install via VS code

However getting the errors as attached.

Hi Abhishek,

Your error shows that there was an issue with the network connectivity. Please make sure you have a stable network connection and also maybe some firewall is preventing the github website.

Please make sure your internet connection is stable and that you can access github.com through a web browser.

After everything is checked, then do the "west update"

I was able to complete the setup without any errors.

The J-Link Plus also showed up in the "CONNECTED DEVICES"

However after restarting the Laptop, it comes back to the same behavior where the J-Link is not detected and not shown in the CONNECTED DEVICES.

Also no support information is shown in the Output.

Anyways I have given up and shifted to another PC where it works.

Thanks a lot
