Getting Started with Kubos Linux and the Kubos SDK¶
This is intended to be a quick guide to creating a new Kubos Linux project using the Kubos SDK.
Creating your Project¶
Method 1: Kubos Init¶
The simplest way to create a new Kubos Linux project is by using the Kubos CLI.
kubos init --linux command takes a project name and creates the project
files and folders.
Inside of the build system there are several reserved words, which
cannot be used as the name of the project. The most common of these are
yotta, the build system the Kubos CLI is based upon, requires project names to be hyphen-delimited or underscore-delimited. CamelCased project names will cause warnings.
$ kubos init -l myproject
init command creates a new directory with the
included so you can get started right away. The
tells the CLI that a Kubos Linux project should be created.
Method 2: Cloning a Project¶
We have also created several different example Kubos projects which can be used as starting points.
If you would like to use one of our projects, you will need to clone the main repo and then link the necessary files. For example:
$ git clone https://github.com/kubos/kubos myproject $ cd myproject/examples/kubos-linux-example $ kubos link --all
It is unnecessary to run the
kubos init command in this case
Editing the project¶
Whether you have cloned your Kubos project or created it with the Kubos CLI, the
default source code entry point is at
There may be additional source files in the
directory, depending on the specific project that you are working with. Each of
our example applications have a main.c source file as the entry point of the
Choosing a Target¶
Once you have created a project you will need to select a target. The target defines which hardware your project will run on and how the peripherals are configured.
You can see a list of available projects by running the following command:
$ kubos target --list
For this example we will set the x86-native-linux target:
$ kubos target x86-linux-native
For more information, see our documentation on Selecting a Target
Building and Flashing¶
Now that the target is set you can begin building. This command will build the current project:
$ kubos build
You should see the
Build Succeeded message! You are now ready to run your
$ kubos flash
Using the x86-linux-native target will cause the project to execute within your Kubos Vagrant image. All output will be routed to your console.
The output should look like this:
Initializing CSP Starting example tasks Ping result 44 [ms] Packet received on MY_PORT: Hello World Ping result 8 [ms] Packet received on MY_PORT: Hello World Ping result 86 [ms] Packet received on MY_PORT: Hello World
Press CTRL+C to stop execution
Congratulations! You have just created, built, and run a basic Kubos project.
If you would like to run this project on a physical board, you’ll follow this same process,
except you’ll select a different hardware target and the target board will need to be
connected to your computer and powered before running the
kubos flash command.
More information about the available targets can be found in the SDK Cheatsheet.
If you build a project and then change its target, you will need to rebuild the project
for the new target with the
kubos build command in order to create a new compatible
binary to use with
