Getting Zephyr¶

Note that a complete Getting Started Guide including installation instructions for different OSs is available in the Zephyr Project documentation.

Here, we will focus on a Ubuntu Linux based environment for simplicity and clarity.

First, you will need to install the following prerequisities:

sudo apt-get install --no-install-recommends git cmake ninja-build gperf \
  ccache dfu-util device-tree-compiler wget python3-pip python3-setuptools \
  python3-wheel xz-utils file make gcc gcc-multilib

Then, download the Zephyr source code and install additional dependencies:

git clone https://github.com/zephyrproject-rtos/zephyr
cd zephyr
pip3 install --user -r scripts/requirements.txt

Set up the environment (do this always for a shell where you will be compiling/running Zephyr):

export ZEPHYR_TOOLCHAIN_VARIANT=zephyr
export ZEPHYR_SDK_INSTALL_DIR="/opt/zephyr-sdk/"
. ./zephyr-env.sh

Download and install Zephyr SDK (note that you can use a different directory for the SDK installation by changing the shell variable set in the snippet above; the value used here is just a sane default):

wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.10.0/zephyr-sdk-0.10.0-setup.run
sudo sh zephyr-sdk-0.10.0-setup.run -- -d $ZEPHYR_SDK_INSTALL_DIR
