I am trying to develop a Globalstar ST150M The project board is a Nordic Semiconductor nRF 52840 DK running an Arm Cortex M4 CPU.

Mark O

I'm using a Windows 11 IBM computer. I have gone thru the Dev Academy exercise 1. I installed the software's, nRf for Desktop, nRF Connect SDK, its toolchain, VS Code IDE as well as the Segger J-Link 7.94e application .I then created  and built the project, as per the Dev Academy tutorial, named Blinki_Tutorial

The nRF52480DK board is not found in the VS Code app.

I can communicate with the board through Putty and other terminal applications, so I know the is a serial connection between the board and computer, however I cannot get the SDK/IDE to recognize the board.

Please advise

    Hello Mark,

    I believe this issue is caused by an incorrect JLink USB driver install. 

    Begin by downloading JLink from this link: https://www.segger.com/downloads/jlink/

    During installation, select "Install legacy USB Driver for J-Link" and "Update existing installation."

    Close VScode and open it again after this installation and you should be able to program the devkit.

    Thanks,

    Helmul, than you for your response.  I tried installing the current version Segger JLink 7.94e, driver, and following the instructions you provided, setting it up for legacy USB Driver, and updating the current instillation. I still could not see the board in the "connected devices" fiel in Visual Studio code. I then tried completly uninstalling the JLink application from the computer and re ran the instillition., making sure I selected run as administrator. I stll can't see the board.

    Additionally, I now can't terminal into the board with Putty, or a terminal session in Visual Studio, as I could before. I moved the board to another computer, that doesn't have any of the Nordic, Segger, or Visual Studio app's and I could terminal into the board as before.

    I take it that the Segger JLink app is the serial access from the SDK/IDE Application to the board. 

    This is a screen shot from nRF Connect Desktop - Terminal..  I'm installing the Segger JLink usb driver V 7.94e, is this perhaps the wrong one? 

    Thank you
