Updating tools and repositories¶
After you install the nRF Connect SDK, regularly check for updates to tools and repositories. The west tool is updated regularly, like any other required Python dependency package.
You might also want to switch to a newer release or check out the latest state of development. However, if you work with a specific release of the nRF Connect SDK, you do not need to update your repositories, because the release will not change. For an overview of changes in the latest releases, see Release notes.
To update west, run the following command in the command window:
pip3 install -U west
pip3 install --user -U west
pip3 install -U west
This command updates west to the latest available version in the PyPi repository.
To manage the
nrf repository (the manifest repository), use Git.
To make sure that you have the latest changes, run
git fetch origin to fetch the latest code from the sdk-nrf repository.
Checking out a branch or tag in the
nrf repository gives you a different version of the manifest file.
west update updates the project repositories to the state specified in this manifest file.
To switch to release v1.7.1 of the nRF Connect SDK, enter the following commands in the
git fetch origin git checkout v1.7.1 west update
To update to a particular revision (SHA), make sure that you have that particular revision locally before you check it out (by running
git fetch origin):
git fetch origin git checkout 224bee9055d986fe2677149b8cbda0ff10650a6e west update
To switch to the latest state of development, enter the following commands:
git fetch origin git checkout origin/master west update
west update every time you change or modify the current working branch (for example, when you pull, rebase, or check out a different branch).
This will bring the project repositories to the matching revision defined by the manifest file.
Each new release of the nRF Connect SDK might require manually updating to a newer version of the SEGGER Embedded Studio (SES) Nordic Edition. Whenever you update to a newer release of the nRF Connect SDK, check the Requirements page for the given release to see if you are using the minimum required version of the SES Nordic Edition.
Because of the custom nRF Connect SDK options available only in the SES Nordic Edition, notifications about newer versions of SES are disabled in the SES Nordic Edition.
To update to the latest version of the SES Nordic Edition, use one of the following options:
Install the latest version of Toolchain Manager as described in Installing automatically.
Install the SES Nordic Edition manually as described in SEGGER Embedded Studio Nordic Edition.
Then, set up the build environment in SES again.
Before the nRF Connect SDK version 1.3.0, the Git repositories were moved from the NordicPlayground GitHub organization to the nrfconnect organization.
They were also renamed, replacing the
fw-nrfconnect- prefix with
The full list of repositories with their old and new URLs is in the following table:
File system path
If you cloned the repositories before the move, your local repositories and forks of the nRF Connect SDK repositories are automatically be redirected to the new ones. However, you should point them directly to their new locations as described in this section.
To change the remotes, complete the following steps:
Rename any personal forks that you have of the nRF Connect SDK repositories to their new names:
Visit your personal fork in a browser. For example, to rename the fw-nrfconnect-nrf repository, access your fork on GitHub (
https://github.com/<username>/fw-nrfconnect-nrf, where <username> is your GitHub account name).
Switch to the Settings tab and edit the name in the Repository name field to
Rename the remotes:
Go to your local copy of each of the repositories listed in the preceding table.
Enter the following command:
git remote set-url remote_name new_url
In this command, replace remote_name with the name of your remote (for example,
originfor your fork or
ncsfor the upstream repository) and new_url with the URL of your fork or the new URL from the preceding table. If you are not sure about the remotes that are configured in your local repository, enter
git remote -vto see your remotes.
For example, to point your existing fw-nrfconnect-nrf clone to its new URL, enter the following command:
cd ncs/nrf git remote set-url origin https://github.com/nrfconnect/sdk-nrf
Similarly, to point your existing fw-nrfconnect-zephyr clone to the new URL, enter the following command:
cd ncs/zephyr git remote set-url ncs https://github.com/nrfconnect/sdk-zephyr
