# Install Digi Embedded Yocto

If you already have a Digi Embedded Yocto version, go to Update Digi Embedded Yocto.

## Install Digi Embedded Yocto 2.2

If this is the first dey-2.2 installation, follow these steps:

1. Install the repo tool.

To install Digi Embedded Yocto, you need the repo tool. Download repo to a directory within your path and add execution permissions.

    ~> sudo curl -o /usr/local/bin/repo http://commondatastorage.googleapis.com/git-repo-downloads/repo
    ~> sudo chmod a+x /usr/local/bin/repo

2. Create an installation folder.
   The installation folder requires user write permissions. For example, create the directory /usr/local/dey-2.2, and navigate to that folder:

    ~> sudo install -o <your-user> -g <your-group> -d /usr/local/dey-2.2
    ~> cd /usr/local/dey-2.2

You can use the id command to get your primary user and group.

4. Use repo to download Digi Embedded Yocto.

Install Digi Embedded Yocto from the morty release branch. This allows you to keep up to date with Digi and the Yocto community fixes.

    ~> repo init -u https://github.com/digi-embedded/dey-manifest.git -b morty
    ~> repo sync -j8 --no-repo-verify

## Update Digi Embedded Yocto

The Digi Embedded Yocto update process is different depending on your current Digi Embedded Yocto version.

### Update an existing dey-2.2 installation

To update a previous dey-2.2 release, sync your installation with the head of the release branch:

    ~> repo sync -j8 --no-repo-verify

### Update an existing installation older than dey-2.2

If you are updating from a previous major release like dey-2.0, you must install the new Digi Embedded Yocto release in a new directory. Follow the steps in Install Digi Embedded Yocto to download the new version.

CAUTION! You must recreate older projects for Digi Embedded Yocto 2.2.
