Zephyr SDK
|
|
##########
|
|
|
|
The Zephyr Software Development Kit (SDK) contains toolchains for each of
|
|
Zephyr's supported architectures. It also includes additional host tools, such
|
|
as custom QEMU and OpenOCD.
|
|
|
|
Use of the Zephyr SDK is highly recommended and may even be required under
|
|
certain conditions (for example, running tests in QEMU for some architectures).
|
|
|
|
Supported architectures
|
|
***********************
|
|
|
|
The Zephyr SDK supports the following target architectures:
|
|
|
|
* ARC (32-bit and 64-bit; ARCv1, ARCv2, ARCv3)
|
|
* ARM (32-bit and 64-bit; ARMv6, ARMv7, ARMv8; A/R/M Profiles)
|
|
* MIPS (32-bit and 64-bit)
|
|
* Nios II
|
|
* RISC-V (32-bit and 64-bit; RV32I, RV32E, RV64I)
|
|
* x86 (32-bit and 64-bit)
|
|
* Xtensa

|
Installation bundle and variables
|
|
*********************************
|
|
|
|
The Zephyr SDK bundle supports all major operating systems (Linux, macOS and
|
|
Windows) and is delivered as a compressed file.
|
|
The installation consists of extracting the file and running the included setup
|
|
script. Additional OS-specific instructions are described in the sections below.
|
|
|
|
If no toolchain is selected, the build system looks for Zephyr SDK and uses the toolchain
|
|
from there. You can enforce this by setting the environment variable
|
|
:envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``zephyr``.
|
|
|
|
If you install the Zephyr SDK outside any of the default locations (listed in
|
|
the operating system specific instructions below) and you want automatic discovery
|
|
of the Zephyr SDK, then you must register the Zephyr SDK in the CMake package registry
|
|
by running the setup script. If you decide not to register the Zephyr SDK in the CMake registry,
|
|
then the :envvar:`ZEPHYR_SDK_INSTALL_DIR` can be used to point to the Zephyr SDK installation
|
|
directory.
|
|
|
|
You can also set :envvar:`ZEPHYR_SDK_INSTALL_DIR` to point to a directory
|
|
containing multiple Zephyr SDKs, allowing for automatic toolchain selection. For
|
|
example, you can set ``ZEPHYR_SDK_INSTALL_DIR`` to ``/company/tools``, where the
|
|
``company/tools`` folder contains the following subfolders:
|
|
|
|
* ``/company/tools/zephyr-sdk-0.13.2``
|
|
* ``/company/tools/zephyr-sdk-a.b.c``
|
|
* ``/company/tools/zephyr-sdk-x.y.z``
|
|
|
|
This allows the Zephyr build system to choose the correct version of the SDK,
|
|
while allowing multiple Zephyr SDKs to be grouped together at a specific path.

.. _toolchain_zephyr_sdk_install_linux:
|
|
|
|
Install Zephyr SDK on Linux
|
|
***************************
|
|
|
|
#. Download and verify the `latest Zephyr SDK bundle`_:
|
|
|
|
.. code-block:: bash
|
|
|
|
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/zephyr-sdk-0.15.2_linux-x86_64.tar.gz
|
|
wget -O - https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.15.2/sha256.sum | shasum --check --ignore-missing
|
|
|
|
You can change ``0.15.2`` to another version if needed; the `Zephyr SDK
|
|
Releases`_ page contains all available SDK releases.
|
|
|
|
If your host architecture is 64-bit ARM (for example, Raspberry Pi), replace
|
|
``x86_64`` with ``aarch64`` in order to download the 64-bit ARM Linux SDK.
|
|
|
|
#. Extract the Zephyr SDK bundle archive:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd <sdk download directory>
|
|
tar xvf zephyr-sdk-0.15.2_linux-x86_64.tar.gz
|
|
|
|
#. Run the Zephyr SDK bundle setup script:
|
|
|
|
.. code-block:: bash
|
|
|
|
cd zephyr-sdk-0.15.2
|
|
./setup.sh
|
|
|
|
If this fails, make sure Zephyr's dependencies were installed as described
|
|
in :ref:`Install Requirements and Dependencies <linux_requirements>`.
|
|
|
|
If you want to uninstall the SDK, remove the directory where you installed it.
|
|
If you relocate the SDK directory, you need to re-run the setup script.
|
|
|
|
.. note::
|
|
It is recommended to extract the Zephyr SDK bundle at one of the following
|
|
default locations:
|
|
|
|
* ``$HOME``
|
|
* ``$HOME/.local``
|
|
* ``$HOME/.local/opt``
|
|
* ``$HOME/bin``
|
|
* ``/opt``
|
|
* ``/usr/local``
|
|
|
|
The Zephyr SDK bundle archive contains the ``zephyr-sdk-0.15.2`` directory and, when
|
|
extracted under ``$HOME``, the resulting installation path will be
|
|
``$HOME/zephyr-sdk-0.15.2``.
