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,

Helmut Lord

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

I can't get a good shot of my Device manager right now.

The Seeger SMD drive is not showing up, nor the Jlnk Portable device and certianly not the com ports.

Sompthind is missing.

Am I supposed to have an actual Seegar Debugger installed? I didn't see it in the Nordic Acamedy instructions.

Gan you send me a picture of your DK, with USB cable plugged in and tell me which leds are on, blinking, or off?

Kenneth, here is my board. I connected power to the USB DC Input, P18, and the computer input to the USB Client connector J1

There are two LED's on continuously, none other are on or blinking.

The development kit you have there is not our nRF52840-DK, which looks like this:
https://www.nordicsemi.com/Products/Development-hardware/nRF52840-DK 

The nRF52840-DK we provide also include an interface MCU that can be used for programming and debugging, ref it's user guide:
https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/if_mcu.html 

For the DK you have it may look like there is no interface MCU that can be used for programming and debugging, likely it's pre-programmed with firmware that allow AT commands developed by Globalstar to use their module, ref their quick start guide:
https://ba6839db-e1e9-457a-87bd-14abd0827fdf.usrfiles.com/ugd/ba6839_cc448b5a7ebe49e181640befc7f9e533.pdf?ST150M-Dev-Kit-Quick-Start-Guide 

So the DK you have is for specific use case, if you want to develop generic products and run the devacademy tutorial you should order yourself an nRF52840-DK, for instance from:
https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-DK/8593726

Kenneth.

My sincere apologies for taking your time.

I totally misunderstood instructions I got for this development. 

Thank you very much for helping me figure this out. I'm new to this field and so learning.

I'll get in touch with Anthony Oliveri, the sales engineer who contacted me about this case, and let him know were all good.

I have ordered an nRF52840 DK for other IOT applications I have

Thanks again

Please close case number 325235

Sounds good. Don't hesitate to reach out to us again once you get a proper nRF52840-DK.

Best regards,
Kenneth
