nRF52 DK - Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

[BAW]

Hello,

I am new to Nordic devices. I just purchased a brand new nRF52 DK.

I am on a Windows 10 machine.

I installed nrfconnect-setup-4.1.2-x64.exe and am trying to use the programmer to Getting started with nRF52 Series — nRF Connect SDK 2.4.99 documentation (nordicsemi.com) install the nRF52 DK Peripheral UART demo.zip.

I see two associated COM ports on my computer:

It also opens up an MSD File Explorer window:

Within the programmer I see the following:

When I select J-Link I see Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

I looked at other related threads, A number of them were for custom boards or stating to try the latest version of nrfconnect-setup.

This is a brand-new board out of the box (not custom) and I believe I am using the newest version of nrfconnect-setup - 4.1.2.

Can anyone provide some help as to what I need to do to get this working properly?

Thanks,

Brent

Hi,

Have you installed nRF Command Line tools?

Can you use that and run:

nrfjprog -v

What does it return?

Can you also do:

nrfjprog --ids

What does it return?

What developing environment are you going to use, nRF Connect SDK or nRF5SDK?

and lastly, can you go through each step in this thread and confirm that none of them solved your issue?

regards

Hi Jared,

Thanks for the response. I installed the nRF Command Line tools.

nrfjprog -v give me the following:

nrfjprog --ids gives me the following:

So, I missed a step somewhere and did not install J-Link. I found the following link:

https://www.segger.com/downloads/jlink/

I assume based on the error I would need to use the Windows ARM installer?

As far as the development environment. In our use case, our product will be using a nRF52805. We are using a nRF52 DK for development. In our product we will be using an app to communicate with the nRF52805 part. The nRF52805 part will be communicating over SPI to another processor.

I have looked at:

https://www.nordicsemi.com/Products/Development-software/nrf-connect-sdk

and 

https://www.nordicsemi.com/Products/Development-software/nrf5-sdk

Do you have a suggestion for which development environment we should use?

Thanks again for your help,

Brent

Brent,

What you want is to download nRF Command Line Tools that includes J-link and other SEGGER sw needed to program our devkits and ICs, you can download it here,

See this and this,

I would recommend nRF Connect SDK since you're starting on a new project. The learning curve might be a bit steep, but I think it will be worth it at the end, and we also have the great Dev-academy to help you learn the basics + more,

Thanks for the response Jared.

I had installed the nRF Command Line Tools as I described above from this link:

nRF Command Line Tools - Downloads - nordicsemi.com

Again, when I type the commands that you mention I get the following errors:

You mention above - "What you want is to download nRF Command Line Tools that includes J-link and other SEGGER sw needed to program our devkits and ICs, you can download it here,"

but I do not see a link to download??

Is the link I downloaded and installed the tools the correct link?

If so, can you help me understand why I am getting the errors and what I need to do to resolve them?

Thanks for your help,

Brent

I'm very sorry that I missed that part, but that was exactly the link that I tried to share. Have you tried to reinstall it as suggested by the error message?

Also, the error message suggest that you run the command again with the --log argument appended, so like this:

nrfjprog -h --log

that will reproduce a log that is more verbose. Can you upload that log here? Just drag and drop the file into the reply box,

thank you!

Hi Jared,

I uninstalled the command line tools and installed them as an administrator. That seems to have fixed the issue.

Thank you for your help.
