Before running the installation script, ensure that Python,`pip` and`venv` are installed on your system. The script will automatically install`west` and manage the necessary dependencies.

On Ubuntu or similar`apt`-based distros, make sure to run the following command:

sudo apt install python3-pip python3-setuptools python3-venv build-essential git cmake ninja-build zstd jq

Make sure you have Homebrew installed. Then run:

xcode-select --install

brew install python cmake ninja zstd jq git

Note: Homebrew’s Python installation already includes`pip`,`setuptools` and`venv`.

If the board is fully supported by Zephyr, you can flash the firmware directly onto the board using the following command:

To flash the loader, run:

west flash

west flash -d build/<variant-name>

The`<variant-name>` appears in the build output when you run the build script. For example:

% ./extra/build.sh portentah7

Build target: arduino_portenta_h7@1.0.0//m7

Build variant: arduino_portenta_h7_stm32h747xx_m7

-- west build: generating a build system

...

In this case, you would flash with:

west flash -d build/arduino_portenta_h7_stm32h747xx_m7

This can also be performed via the "Burn bootloader" action in the IDE if the core is properly installed, as detailed below.

After running the`bootstrap.sh` script, you can symlink the core to`$sketchbook/hardware/arduino-git/zephyr`. Once linked, it will appear in the IDE/CLI, and the board's Fully Qualified Board Name (FQBN) will be formatted as`arduino-git:zephyr:name_from_boards_txt`.

Remember to also install and/or update the officially published core in the IDE Board Manager to get the latest tools and dependencies.
