| 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. |
| |
| Build Host |
| ---------- |
| |
| |TF-A| can be built using either a Linux or a Windows machine as the build host. |
| |
| A relatively recent Linux distribution is recommended for building |TF-A|. We |
| have performed tests using Ubuntu 16.04 LTS (64-bit) but other distributions |
| should also work fine as a base, provided that the necessary tools and libraries |
| can be installed. |
| |
| .. _prerequisites_toolchain: |
| |
| Toolchain |
| --------- |
| |
| |TF-A| can be built with any of the following *cross-compiler* toolchains that |
| target the Armv7-A or Armv8-A architectures: |
| |
| - GCC >= 10.2-2020.11 (from the `Arm Developer website`_) |
| - Clang >= 4.0 |
| - Arm Compiler >= 6.0 |
| |
| In addition, a native compiler is required to build the supporting tools. |
| |
| .. note:: |
| The software has also been built on Windows 7 Enterprise SP1, using CMD.EXE, |
| Cygwin, and Msys (MinGW) shells, using version 5.3.1 of the GNU toolchain. |
| |
| .. note:: |
| For instructions on how to select the cross compiler refer to |
| :ref:`Performing an Initial Build`. |
| |
| .. _prerequisites_software_and_libraries: |
| |
| Software and Libraries |
| ---------------------- |
| |
| The following tools are required to obtain and build |TF-A|: |
| |
| - An appropriate toolchain (see :ref:`prerequisites_toolchain`) |
| - GNU Make |
| - Git |
| |
| The following libraries must be available to build one or more components or |
| supporting tools: |
| |
| - OpenSSL >= 1.0.1 |
| |
| Required to build the cert_create tool. |
| |
| The following libraries are required for Trusted Board Boot support: |
| |
| - mbed TLS == 2.26.0 (tag: ``mbedtls-2.26.0``) |
| |
| These tools are optional: |
| |
| - Device Tree Compiler (DTC) >= 1.4.6 |
| |
| 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 5 (DS-5)`_ |
| |
| The standard software package used for debugging software on Arm development |
| platforms and |FVP| models. |
| |
| - Node.js >= 14 |
| |
| 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. |
| |
| Package Installation (Linux) |
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| If you are using the recommended Ubuntu distribution then you can install the |
| required packages with the following command: |
| |
| .. code:: shell |
| |
| sudo apt install build-essential git libssl-dev |
| |
| The optional packages can be installed using: |
| |
| .. code:: shell |
| |
| sudo apt install device-tree-compiler |
| |
| Additionally, to install an up-to-date version of Node.js, you can use the `Node |
| Version Manager`_ to install a version of your choosing (we recommend 14, but |
| later LTS versions might offer a more stable experience): |
| |
| .. code:: shell |
| |
| curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | "$SHELL" |
| exec "$SHELL" -ic "nvm install 14; 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: |
| |
| 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" |
| |
| 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 <https://git-scm.com/docs/githooks>`_. |
