### Install the Zephyr build tools

- Follow the Zephyr Project [Getting Started Guide — Zephyr Project Documentation](https://docs.zephyrproject.org/latest/develop/getting_started/index.html) to install the required packages and set up the Zephyr workspace.
- Download and install [arm-gnu-toolchain from Arm GNU Toolchain](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads)
- Download and install the Arm GNU Toolchain from the [Arm GNU Toolchain downloads page](https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads). Select the `arm-none-eabi` package for your host architecture: `aarch64-arm-none-eabi` for aarch64 Linux, or `x86_64-arm-none-eabi` for x86_64 Linux.

The Zephyr hello_world sample prints “Hello World” to the console. Use it to validate that your board support and toolchain configuration work.

1. Activate your Python virtual environment for Zephyr.
2. Set the toolchain environment variables. Replace <toolchain_install_path> with the directory where you installed the Arm GNU Toolchain.
2. Set the toolchain environment variables. Set `GNUARMEMB_TOOLCHAIN_PATH` to the directory where you installed the Arm GNU Toolchain. The directory name includes your host architecture: `arm-gnu-toolchain-<version>-aarch64-arm-none-eabi` on aarch64, or `arm-gnu-toolchain-<version>-x86_64-arm-none-eabi` on x86_64.
```bash
export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH=arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi-install-path/
export GNUARMEMB_TOOLCHAIN_PATH=<toolchain_install_path>
```
3. Build the sample for the Corstone-320 FPGA variant:
