Legato Plugin for Visual Studio Code (Linux)
 The Legato Plugin for Visual Studio Code connects the Legato tools into an IDE to ease the learning curve of Legato, and provides a map of the definition system for you to easily build systems for your smart module.

    2. Select the latest package (the first one in the Available list).
    3. Install the SDK to a profile — click Add to profile..., name your profile and then follow any prompts in the terminal window.

Note: All images are contained within the SDK and can be updated from the Target menu using the Flash .cwe/.spk to a target(via swflash) option.
Leaf Workspace Manager

Important: In the 'Search for a target' step, use the following to search for the latest WP77 packages: leaf search -t wp77xx -t stable -t latest
