Thats very unfortunate. I wonder why this move was necessary ....

I understand but we built our entire system on eclipse 3 years ago and it we'll take time to reconfigure it for segger studio.

I'll find a way to configure it on a new computer by myself

Hi Franck,

It's a very old tutorial (from 6 years ago) and was not updated. It's removed because we don't officially support Eclipse with our SDK. It's suggested to use Segger Embedded Studio as the IDE for the SDK. It's free if you use to develop with Nordic SoC.

The link is dead,

I have a new install to do from scratch but it's seems that the tuto was removed fro the website

Did someone knows where I can find the nordic eclipse tutorial ?

You might try importing (into Eclipse) one of my projects on Github, and browsing the Properties of the project. The projects use Eclipse managed build (not manual Makefiles.) I don't think they are too peculiar or have too much cruft. Not saying they will build and run, just display their properties. mcuoneclipse and bitknitting are other resources. I don't know of a very specific tutorial. Search for "Nordic Eclipse managed make"

@butch, having used eclipse properties extensively with software projects but never with embedded, I am looking for any information on setting up the Eclipse properties, as this is a much more ideal solution. Could you recommend a specific resource for learning about setting up the properties for GNU ARM and gcc?

The instructions in the answer are for an example project from the tutorial written by Nordic. Those examples use a Makefile constructed by Nordic, that you might need to modify unless you follow the tutorial exactly with respect to what directory and name you downloaded the SDK to.

It appears that you downloaded a different example project, one from my Github repository. That example does not have a Makefile since Eclipse is smart and "manages the build" that is knows what the source files are, the dependencies between them, and how to link them together. But for that example, some of the paths to the SDK are described in the Properties of the Eclipse project. Thus you must learn how to use the Properties dialog of Eclipse.

You should choose a strategy: 1. use a Nordic example and learn to modify Makefiles, or 2. use my example and learn how to use Eclipse Properties dialog.

I downloaded it from the how to get started guide a while ago, but since then I updated the files with the latest version.

Thanks for the help! I was able to import the archive, but I had to manually replace the /home/butch... entries with my sdk location. Once I did that most of the issues were resolved but all the function calls in counter.cpp were still invalid. Since I don't need that anyway, I just commented everything that was giving an error just to see if I can compile it. When I try to build I get the following errors regarding the makefile: Description Resource Path Location Type Program "" not found in PATH ble_control C/C++ Problem Program "echo" not found in PATH ble_control Project Properties, C++ Preprocessor Include.../Providers, [CDT GCC Built-in Compiler Settings Cross ARM] options C/C++ Scanner Discovery Problem Program "make" not found in PATH nRFCounter C/C++ Problem

I am not really an expert in tailoring makefiles, I only used it for simple C projects. How do I fix the makefile?

@Dajgoro: Where did you get that nRF5x_MDK_8_9_0 from ?

Using Eclipse, to import an example file from the Nordic tutorial:

Download the example, say to Download/foo.zip
Start Eclipse
Choose File>Import. Expect a dialog titled "Import" to open.
Select (click on) "General>Existing projects into workspace". Choose the "Next" button. Expect another dialog saying "Select a directory to search for existing Eclipse projects".
Select the radio button "Select archive file". Choose the "Browse" button. Expect a file chooser dialog to open.
Browse to and select the file "Downloads/foo.zip". Choose the "OK" button. Expect the file chooser dialog to close and for the previous dialog to reappear, now with the "Finish" button enabled.
Choose the "Finish" button. Expect the dialog to close and for a new project to appear in the "Project Explorer" pane of Eclipse.

I tested this with Eclipse Neon version on Linux. It might be slightly different with other OS or version of Eclipse.

You might still need to edit the Makefile if you did not follow the tutorial exactly with respect to where you downloaded the SDK, which SDK you downloaded, or other matters. For example, today the tutorial only has an example project for blinky and SDK11. If you try to use SDK12 with that example project, you might need to edit the Makefile (because the filenames changed, and the SDK changed.) The recommendation is to follow the tutorial exactly.

No, I was wrong. You need to choose either the archive or the "root directory" that was unzipped, when importing a project into Eclipse. The archive must contain a ".project" file, but you choose the directory above it. See my answer below

I think Eclipse, to import a project, wants a file with suffix ".project". In other words, a file whose contents is XML that describes the settings and location of source files for the "project".

So this is what I have: I downloaded everything as on the tutorial, and I got a folder called nRF5x_MDK_8_9_0 which inside has examples with the ARMGCC folder and inside there is the makefile, when I try to import with eclipse, and select such a folder with makefile nothing happens, as if it was empty, nothing detected. In program files (C:\Program Files (x86)\Nordic Semiconductor) there are no examples and no ARMGCC folders, I suppose the sdk is here? There is no error when importing with eclipse, because there is nothing it detects to import.

I have several Eclipse/NRF52 projects on Github, and you can probably find others there. For example github.com/.../nRFCounter.git. However, that project does not use Makefiles as in the tutorial, but uses "Eclipse managed build" which requires more knowledge about how to use Eclipse especially the Properties of a project. Re your specific problem of importing the example project, what exact error do you get (you have only said "there is no armcc folder in my SDK.") The tutorial example uses a Makefile which defines the location of your downloaded SDK. Did you download your SDK to the exact same location as the tutorial?

@Dajgoro: I'm sorry that you have trouble porting to Eclipse. I think it's a typo in the tutorial, it should be ARMGCC folder, not ARMCC. There are several attached projects in the tutorial (at the end of the tutorial, before the comments), could you try ? Which SDK you are testing with ?

Please let me know at which step, what you have on your computer doesn't match with what described in the tutorial.

I did not, I could not import any project because the importing tool from eclipse never recognized any projects in the example folder. So I went the other way of trying to create a new project from exiting keil project. Then I had to create the virtual folders and link all of the files and includes manually as the tutorial stated. Once I did that eclipse recognized all of the includes, but it had no effect on the code, since all of the error remained. Then I went googling trying to find at least a blinky project that has been exported from eclipse but I could not find anything. So that is why I am asking if somebody has anything that I could import in eclipse that works so I can try fix the configuration, if that is the cause, or its just me not doing something right with my project.

Hung Bui — Wed, 15 Mar 2017 12:00:37 GMT

You mentioned "And after a while I got eclipse to handle the Nordic stuff" have you managed to compile any example in our SDK ? Which project are you trying to port ? Was it in Keil or IAR or others ?
