Building a Platform using Stuart

To take your firmware code tree from freshly cloned to fully built, you only need to execute three commands. If you've properly installed edk2-pytool-extensions, then these commands will be available to execute as seen below:

stuart_setup -c path/to/
stuart_update -c path/to/
stuart_build -c path/to/


Review your platform's instructions as it is common to install any additional python requirements via the command pip install --upgrade -r pip-requirements.txt, where pip-requirements.txt contains the necessary python requirements.

Stuart provides platforms the ability to customize it's build via command flags. Due to this Your platform's build instructions is the single source of truth.


Once you've run stuart_setup and stuart_update, building your platform again is as simple as executing stuart_build -c path/to/

As you can see, Each of these commands has a single required flag -c that points towards a platform's settings file. This is a python file that is typically located in the same directory as the platform's DSC file, however refer to your platform's build instructions for the exact name and location of this file.


Common to most command line tools, you can use -h, --help on any of the commands to find any options. Using it with stuart_build can be particularly useful as it will provide you with common env variable overrides to customize the build: stuart_build -c <filepath> --help

Curious about what each command does? Check out the below sections.


Stuart_setup is responsible for downloading all git submodule dependencies as specified by your platform.

stuart_setup -c path/to/


Stuart_update is responsible for downloading all other required external dependencies, including, but not limited to nuget, azure, etc.

stuart_update -c path/to/


Stuart_build is responsible for building the platform and placing all artifacts in the /Build/ directory. Refer to your platform's build instructions for any additional build flags needed to build.

stuart_build -c path/to/

As mentioned previously, using the -h, --help flag can be particularly useful as it will provide you with common env variable overrides to customize the build.

stuart_build -c path/to/ --help


Can I pass build values through stuart to the build command?

Yes! Build values can be set and passed to the build command via the command line or from within your platform build file Read More. You define a build value via BLD_*_<VAR>=<VALUE> for all builds, BLD_DEBUG_<VAR>=VALUE for debug builds, and BLD_RELEASE_<VAR>=VALUE for release builds.

Non-valued build defines are also supported! Simply follow the above nomenclature without providing a value i.e. VLD_*_<VAR>

From the command line:

\> stuart_build -c Platforms/QemuQ35Pkg/ BLD_*_SHIP_MODE=FALSE
\> stuart_build -c Platforms/QemuQ35Pkg/ BLD_*_E1000_ENABLE

From within the Platform build file:

def SetPlatformEnv(self):
    self.env.SetValue("BLD_*_SHIP_MODE", "FALSE", "Default")
    self.env.SetValue("BLD_*_E1000", None, "Default")
