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

Best regards,
Kenneth

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

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:

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.

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

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.

Kenneth — Wed, 17 Apr 2024 18:25:52 GMT

The only thing I can think of is some kind of driver issue, is there any unknown devices in device manager? Here is how it looks at my place using Windows 11 also:

I ran nrfjprog --recover and I still can't see the board in VS code

Kenneth — Wed, 17 Apr 2024 15:11:12 GMT

Looks good, does running 'nrfjprog --recover' work?

Edit: If that works, then I would try to go back to VS code and check.

Type 'cmd' in Windows to open a command line window.

Thank you Kenneth. I have nRF command line Tools and will try this. At this time on my developnment computer, I am no longer able to connect to the board with any terminal program (previously, I could connect to the board with Putty). The original com port, nor any other I choose in "Putty" are avaliable.

Can you tell me what version of 'nfrjprog" I shoud load?

Thank you

Ok, I got back to the shop, figured out what the terminal connection problem was, now I'm trying to get the 'nrfjprog' version, but keep getting an invlad command error

What is the proper snytex for that commnd?

Ok here it is

Can you also try to install nRF Command line tools and then run 'nrfjprog --version' in a command line window?

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

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
