Building app with nRF Connect SDK in private repo

BVajda

We would like the ability to build our application using a version of the nRF Connect SDK that we have in a private repo. This is desirable for both long term maintenance, as well as capturing any changes we make to the SDK (such as the private key used in app signing).

We are able to build the app using the standard build process described in the SDK documentation. However, we are having issues building the same app when using a version of the SDK in our own git repo. The main problem lies with the cmake command to configure Ninja. We get a cmake error trying to resolve the mbedtls project (despite it's presence in the build directory).

Here is the build output:

As a general question, what is the preferred approach to using a private repo for the SDK? The approach I took was admittedly brute force; basically taking the my local copy of the SDK, stripping the .git information, and committing the whole SDK into our repo.

Thanks-

    Hi Brian,


    I would suggest making a fork of the nrf repo.

    (https://github.com/NordicPlayground/fw-nrfconnect-nrf)

    Then you would need to clone that fork to your local computer:

    mkdir ncs && cd ncs
git clone https://github.com/<username>/fw-nrfconnect-nrf nrf

    Then you add the upstream repository as remote:

    cd nrf
git remote add ncs https://github.com/NordicPlayground/fw-nrfconnect-nrf
git remote -v

    Then you 'checkout' the latest stable tag (v1.0.0) and make a branch of that:

    git checkout v1.0.0
git checkout -b <new-branch-name>

    Then you would need to initialize west and get the other repositories:

    cd ..
west init -l nrf
cd nrf
west update

    and then you can 'git push' to get the changes up to your github.

    git push --set-upstream origin <name_of_your_branch>

    When there comes some new updates from upstream you can get those by:

    cd nrf
git checkout master
git fetch ncs
git merge ncs/master

     

    Best Regards,

    Martin L.
