TF-M build instruction

Please make sure you have all required software installed as explained in the software requirements.

TF-M build steps

TF-M uses cmake to provide an out-of-tree build environment. The instructions are below.

External dependency

CMSIS_5 is used to import RTX for tests and apps
mbedtls is used as crypto library on the secure side

Both need to be cloned manually in the current release.

Build steps:

cd <TF-M base folder>
git clone https://github.com/ARM-software/trusted-firmware-m.git
git clone https://github.com/ARMmbed/mbedtls.git -b mbedtls-2.5.1
git clone https://github.com/ARM-software/CMSIS_5.git
cd trusted-firmware-m
mkdir cmake_build
cd cmake_build
cmake ../ -G"Unix Makefiles"
make

Regression Tests

The default option build doesn't include regression tests. Procedure for building the regression tests is below.

It is recommended that tests are built in a different directory.

TF-M build regression tests on Linux

cd <TF-M base folder>
cd trusted-firmware-m
mkdir cmake_test
cd cmake_test
cmake -G"Unix Makefiles" -DPROJ_CONFIG=`readlink -f ../ConfigRegression.cmake` ../
make

TF-M build regression tests on Windows

cd <TF-M base folder>
cd trusted-firmware-m
mkdir cmake_test
cd cmake_test
cmake -G"Unix Makefiles" -DPROJ_CONFIG=`cygpath -m ../ConfigRegression.cmake` ../
make

Export dependency files for NS applications

An NS application requires a number of files to run with TF-M. The build system can export these files using "install" target in to a single folder.

On Windows

cmake -G"Unix Makefiles" -DPROJ_CONFIG=`cygpath -m ../ConfigRegression.cmake` ../
make install

On Linux

cmake -G"Unix Makefiles" -DPROJ_CONFIG=`readlink -f ../ConfigRegression.cmake` ../
make install

The integration guide explains further details of creating a new NS app.
