This tool fetches the pre-built files that are associated with the current revision of the Arduino core for Zephyr. This makes it possible to use the repository as a local core with the Arduino IDE without the need to have the full Zephyr build system installed and configured.

Pre-built files are generated only for the most recent commits in each branch. If in doubt, checkout the current version of the branch you are interested in before running the tool.

If you have installed the Arduino IDE and the Arduino core for Zephyr, you can find the pre-built files in the .arduino15/packages/arduino/tools/ folder in your home directory. You can directly use the tool from there.

To build the tool, you need to have the Go programming language installed; make sure you have the go command available in your PATH. Then, use the go build command to build the tool for your platform.

To build the full set of binaries for all platforms, run the package_tool.sh script in the parent directory with ../package_tool.sh, or provide the path to this directory as an argument.
