| Trusted Firmware M provides a reference implementation of the Platform Security |
| Architecture (PSA) specifications, aligning with PSA Certified guidelines. |
| It is assumed that the reader is familiar with the specifications that can be |
| found |
| `here <https://developer.arm.com/architectures/security-architectures/platform-security-architecture>`__. |
| |
| The current TF-M implementation on Armv8-M leverages TrustZone for Armv8-M so a |
| good understanding of the v8-M architecture is also necessary. A good place to |
| get started with Armv8-M is |
| `developer.arm.com <https://developer.arm.com/architectures/cpu-architecture/m-profile>`__. |
| |
| ************************** |
| Build and run instructions |
| ************************** |
| Trusted Firmware M source code is available on |
| `git.trustedfirmware.org <https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/>`__. |
| |
| To build & run TF-M: |
| |
| - Follow the this guide to set up and check your environment. |
| - Follow the |
| :doc:`Build instructions </building/tfm_build_instruction>` |
| to compile and build the TF-M source. |
| - Follow the :doc:`Run TF-M examples on Arm platforms </building/run_tfm_examples_on_arm_platforms>` |
| for information on running the example. |
| |

| ######################### |
| Set up build environments |
| ######################### |
| |
| TF-M officially supports a limited set of build environments and setups. In |
| this context, official support means that the environments listed below |
| are actively used by team members and active developers, hence users should |
| be able to recreate the same configurations by following the instructions |
| described below. In case of problems, the TF-M team provides support |
| only for these environments, but building in other environments can still be |
| possible. |
| |
| The following environments are supported: |
| |
| .. tabs:: |
| |
| .. group-tab:: Linux |
| |
| 1. version supported: |
| |
| Ubuntu 18.04 x64+ |
| |
| 2. install dependencies: |
| |
| .. code-block:: bash |
| |
| sudo apt-get install -y git curl wget build-essential libssl-dev python3 \ |
| python3-pip cmake make |
| |
| 3. verify cmake version: |
| |
| .. code-block:: bash |
| |
| cmake --version |
| |
| .. note:: |
| |
| Please download CMake version 3.21 or later from https://cmake.org/download/. |
| |
| 4. add CMake path into environment: |
| |
| .. code-block:: bash |
| |
| export PATH=<CMake path>/bin:$PATH |
| |
| .. group-tab:: Windows |
| |
| 1. version supported: |
| |
| Windows 10 x64 |
| |
| 2. install dependencies: |
| |
| - Git client latest version (https://git-scm.com/download/win) |
| - CMake version 3.21 or later (`native Windows version <https://cmake.org/download/>`__) |
| - GNU make (http://gnuwin32.sourceforge.net/packages/make.htm) |
| - Python3 `(native Windows version) <https://www.python.org/downloads/>`__ and |
| the pip package manager (from Python 3.4 it's included) |
| |
| 3. add CMake path into environment: |
| |
| .. code-block:: bash |
| |
| set PATH=<CMake_Path>\bin;%PATH% |
| |
| ########################### |
| Install python dependencies |
| ########################### |
| |

| Build AN521 regression sample |

| |
| Here, we take building TF-M for AN521 platform with regression tests using GCC |
| as an example: |
| |
| .. tabs:: |
| |
| .. group-tab:: Linux |
| |
| Get the TF-M tests source code: |
| |
| .. code-block:: bash |
| |
| git clone https://git.trustedfirmware.org/TF-M/tf-m-tests.git |
| |
| Build SPE and NSPE. |
| |
| .. code-block:: bash |
| |
| cd </tf-m-tests/tests_reg> |
| cmake -S spe -B build_spe -DTFM_PLATFORM=arm/mps2/an521 -DCONFIG_TFM_SOURCE_PATH=<TF-M source dir absolute path> \ |

| cmake --build build_test |
| |
| .. group-tab:: Windows |
| |
| .. important:: |
| Use "/" instead of "\\" when assigning Windows paths to CMAKE |
| variables, for example, use "c:/build" instead of "c:\\\\build". |
| |
| Get the TF-M tests source code: |
| |
| .. code-block:: bash |
| |
| git clone https://git.trustedfirmware.org/TF-M/tf-m-tests.git |
| |
| Build SPE and NSPE. |
| |
| .. code-block:: bash |
| |
| cd </tf-m-tests/tests_reg> |

| cmake --build build_test |
| |
| .. note:: |
| The latest Windows support long paths, but if you are less lucky |
| then you can reduce paths by moving the build directory closer to |
| the root by changing the ``-B`` option of the commands, for example, |
| to ``C:\build_spe`` and ``C:\build_test`` folders. |
