Prerequisites ============= This document describes the software requirements for building |TF-A| for AArch32 and AArch64 target platforms. It may possible to build |TF-A| with combinations of software packages that are different from those listed below, however only the software described in this document can be officially supported. Getting the TF-A Source ----------------------- Source code for |TF-A| is maintained in a Git repository hosted on `TrustedFirmware.org`_. To clone this repository from the server, run the following in your shell: .. code:: shell git clone "https://review.trustedfirmware.org/TF-A/trusted-firmware-a" Requirements ------------ ======================== ===================== Program Min supported version ======================== ===================== Arm Compiler 6.18 Arm GNU Compiler 13.3 Clang/LLVM 18.1.8 Device Tree Compiler 1.6.1 GNU make 3.81 mbed TLS\ [#f1]_ 3.6.1 Node.js [#f2]_ 16 OpenSSL 1.0.0 Poetry 1.3.2 QCBOR\ [#f3]_ 1.2 Sphinx\ [#f2]_ 5.3.0 ======================== ===================== .. [#f1] Required for Trusted Board Boot and Measured Boot. .. [#f2] Required only for building TF-A documentation. .. [#f3] Required only when enabling DICE Protection Environment support. Toolchain ^^^^^^^^^ |TF-A| can be compiled using any cross-compiler toolchain specified in the preceding table that target Armv7-A or Armv8-A. For AArch32 and AArch64 builds, the respective targets required are ``arm-none-eabi`` and ``aarch64-none-elf``. Testing has been performed with version 13.3.Rel1 (gcc 13.3) of the Arm GNU compiler, which can be installed from the `Arm Developer website`_. In addition, a native compiler is required to build supporting tools. .. note:: Versions greater than the ones specified are likely but not guaranteed to work. This is predominantly because TF-A carries its own copy of compiler-rt, which may be older than the version expected by the compiler. Fixes and bug reports are always welcome. .. note:: For instructions on how to select the cross compiler refer to :ref:`Performing an Initial Build`. OpenSSL ^^^^^^^ OpenSSL is required to build the cert_create, encrypt_fw, and fiptool tools. If using OpenSSL 3, older Linux versions may require it to be built from source code, as it may not be available in the default package repositories. Please refer to the OpenSSL project documentation for more information. .. warning:: Versions 1.0.x and from v3.0.0 up to v3.0.6 are strongly advised against due to concerns regarding security vulnerabilities! Device Tree Compiler (DTC) ^^^^^^^^^^^^^^^^^^^^^^^^^^ Needed if you want to rebuild the provided Flattened Device Tree (FDT) source files (``.dts`` files). DTC is available for Linux through the package repositories of most distributions. Arm Development Studio (`Arm-DS`_) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The standard software package used for debugging software on Arm development platforms and |FVP| models. Node.js ^^^^^^^ Highly recommended, and necessary in order to install and use the packaged Git hooks and helper tools. Without these tools you will need to rely on the CI for feedback on commit message conformance. Poetry ^^^^^^ Required for managing Python dependencies, this will allow you to reliably reproduce a Python environment to build documentation and run some of the integrated Python tools. Most importantly, it ensures your system environment will not be affected by dependencies in the Python scripts. For installation instructions, see the `official Poetry documentation`_. .. _prerequisites_software_and_libraries: Package Installation (Linux) ---------------------------- |TF-A| can be compiled on both Linux and Windows-based machines. However, we strongly recommend using a UNIX-compatible build environment. Testing is performed using Ubuntu 22.04 LTS (64-bit), but other distributions should also work, provided the necessary tools and libraries are installed. The following are steps to install the required packages: .. code:: shell sudo apt install build-essential The optional packages can be installed using: .. code:: shell sudo apt install device-tree-compiler Additionally, to install a version of Node.js compatible with TF-A's repository scripts, you can use the `Node Version Manager`_. To install both NVM and an appropriate version of Node.js, run the following **from the root directory of the repository**: .. code:: shell curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash exec "$SHELL" -ic "nvm install; exec $SHELL" .. _Node Version Manager: https://github.com/nvm-sh/nvm#install--update-script Supporting Files ---------------- TF-A has been tested with pre-built binaries and file systems from `Linaro Release 20.01`_. Alternatively, you can build the binaries from source using instructions in :ref:`Performing an Initial Build`. .. _prerequisites_get_source: Additional Steps for Contributors ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If you are planning on contributing back to TF-A, there are some things you'll want to know. TF-A is hosted by a `Gerrit Code Review`_ server. Gerrit requires that all commits include a ``Change-Id`` footer, and this footer is typically automatically generated by a Git hook installed by you, the developer. If you have Node.js installed already, you can automatically install this hook, along with any additional hooks and Javascript-based tooling that we use, by running from within your newly-cloned repository: .. code:: shell npm install --no-save If you have opted **not** to install Node.js, you can install the Gerrit hook manually by running: .. code:: shell curl -Lo $(git rev-parse --git-dir)/hooks/commit-msg https://review.trustedfirmware.org/tools/hooks/commit-msg chmod +x $(git rev-parse --git-dir)/hooks/commit-msg You can read more about Git hooks in the *githooks* page of the Git documentation, available `here `_. -------------- *Copyright (c) 2021-2024, Arm Limited.
