Looks like your missing a part of the file structure. The "zephyr" folder inside the nrf folder should only contain that one file.

[quote user="chris97"]

I finally got the CMakeLists.txt file which i could specify:

C:/Users/ZIEGER/nrf/applications/asset_tracker/CMakeLists.txt // Done !

[/quote]

From this it looks like you've only installed the nrf folder within the ncs, is this the only files that was installed when using the manual process?

It's another Zephyr folder that's referred to in SEGGER embedded studio, this folder should be located at:

C:/Users/USERNAME/ncs/v1.3.1/zephyr

that's the same folder as the nrf-folder should be in. So the zephyr folder you want is not the one inside the nrf folder but should be one step up in the directory.

You also have to edit the links so that <THESE> corresponds with your file structure, but I guess you got that already.

Best regards

Hi Robin,

thanks for your help so far.

Some of your steps work very well. For example i could give the directory for:

GNU ARM Embedded Toolchain Directory: <NCS>/<ncs-toolchain>/opt
Zephyr Base: <NCS>/zephyr

But there is still something missing by following your recent steps.

Some problems start at step 8 ...

I finally got the CMakeLists.txt file which i could specify:

C:/Users/ZIEGER/nrf/applications/asset_tracker/CMakeLists.txt // Done !

I was also able to get a zephyr folder by installing everything manually.

2. Unzip the ncs-toolchain zip into the folder ...

3. Navigate to the ...

4. ...

5. ... // Done !

etc...

The problem is, that the zephyr folder only includes one single file. The file name is "module.yml" thats it.

So i cant give the correct directory for the board directory. Board directory: <NCS>/zephyr/boards/arm/nrf9160_pca10090

Also the file "build_nrf9160_pca10090ns" does not exist!

Build directory: <NCS>/nrf/applications/asset_tracker/build_nrf9160_pca10090ns //Thats what i was supposed to do. But there is no build_nrf9160_pca10090ns in the asset_tracker folder ...

What can i do now ?

Thank you Robin !

Hi,

Ok, what about "west init --local nrf"? And then "west update", does that work?

Edit: I have been told this is a unzipping-issue, rather than a downloading issue. You could try to unzip and install the SDK manually. To do this you need to find the folder named "downloads" inside the folder named "sdk", this folder should contain a zip-file named "ncs-toolchain-v1.3.1-..."

Here are the instructions for unzipping and installing the sdk manually:

Follow these instructions to install the nRF Connect SDK:

1. Create a folder in which you want to install the nRF Connect SDK.
In the following instructions, we will refer to this folder as <NCS>.

2. Unzip the ncs-toolchain zip into the folder you created by right-clicking
the .zip file and selecting 'Extract All'.
This will create the following folder: <NCS>/<ncs-toolchain>

3. Navigate to the <NCS>/<ncs-toolchain> folder.

4. Double-click `git-bash.exe` to open a command line window from which you
can install the nRF Connect SDK.

5. To clone and update the nRF Connect SDK GitHub repositories, type the following
command and press enter:

ncsmgr init-ncs

6. Double-click `SEGGER Embedded Studio.cmd` to open SEGGER Embedded Studio.

7. In SEGGER Embedded Studio, go to 'Tools' > 'Options' and select the 'nRF Connect' tab.
Set the locations of the GNU ARM Embedded Toolchain and Zephyr.
Use the 'Browse' button to select the following folders:

GNU ARM Embedded Toolchain Directory: <NCS>/<ncs-toolchain>/opt
Zephyr Base: <NCS>/zephyr

8. Click 'File' > 'Open nRF Connect SDK Project' to open a sample application.
For example, to open the Asset Tracker application, select the following values:

CMakeLists.txt: <NCS>/nrf/applications/asset_tracker/CMakeLists.txt
Board directory: <NCS>/zephyr/boards/arm/nrf9160_pca10090
Board name: nrf9160_pca10090ns
Build directory: <NCS>/nrf/applications/asset_tracker/build_nrf9160_pca10090ns

9. Click 'Build' > 'Build' to build the application.
If the application builds without errors, your installation was successful.

You can now start developing your own application!

/Edit

Best regards

Robin

Are you able to run "west update" in command prompt? Click on the little triangle next to "first steps to build", select "open command prompt" and type in "west update" and then press the enter key.

Best regards

Hey

Cloning 1-2 GB of files from our GitHub repositories could be a little unstable. I had this issue myself and solved it by updating the toolchain, and then removing the ncs-version I wanted to use and re-installing it. My colleagues also report that this problem often occurs when using the internet via a VPN-service, so this should be avoided when installing the ncs. All files should be present in ncs v1.3.1, no need to revert back to another version as I erroneously stated earlier.

To update toolchain:
- click the little triangle next to the ncs-version in the toolchain manager
- select "update toolchain"

To remove ncs-version
- click the little triangle and select "remove"

To reinstall ncs-version
- click install

Just update me in this case if this does not solve the issue.

Best regards

Robin

Every sample project has its CMakeLists.txt.

CMakeLists.txt - the location of the CMakeLists.txt project file of the sample that you want to work with
i.e. C:\Users\ZIEGER\ncs\v1.3.1\zephyr\samples\basic\blinky\CMakeLists.txt
Just use this link as a reference. C:\Users\ZIEGER\ncs\v1.3.1\zephyr\samples\basic\blinky\CMakeLists.txt
