Compilation of TF-A (Trusted Firmware-A):
|
|
1. Pre-requisite
|
|
2. Initialize cross-compilation via SDK
|
|
3. Prepare TF-A source code
|
|
4. Manage TF-A source code with GIT
|
|
5. Compile TF-A source code
|
|
6. Update software on board
|
|
|
|
----------------
|
|
1. Pre-requisite
|
|
----------------
|
|
OpenSTLinux SDK must be installed.
|
|
|
|
For TF-A build you need to install:
|
|
- git:
|
|
Ubuntu: sudo apt-get install git-core gitk
|
|
Fedora: sudo yum install git
|
|
|
|
If you have never configured you git configuration:
|
|
$ git config --global user.name "your_name"
|
|
$ git config --global user.email "your_email@example.com"
|
|
|
|
---------------------------------------
|
|
2. Initialize cross-compilation via SDK
|
|
---------------------------------------
|
|
Source SDK environment:
|
|
$ source <path to SDK>/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
|
|
|
|
To verify if your cross-compilation environment have put in place:
|
|
$ set | grep CROSS
|
|
CROSS_COMPILE=arm-ostl-linux-gnueabi-
|
|
|
|
Warning: the environment are valid only on the shell session where you have
|
|
sourced the sdk environment.
|
|
|
|
----------------------
|
|
3. Prepare TF-A source
|
|
----------------------
|
|
If not already done, extract the sources from Developer Package tarball, for example:
|
|
$ tar xfJ en.SOURCES-stm32mp1-*.tar.xz
|
|
|
|
In the TF-A source directory (sources/*/##BP##-##PR##),
|
|
you have one TF-A source tarball, the patches and one Makefile:
|
|
- ##BP##-##PR##.tar.xz
|
|
- 00*.patch
|
|
- Makefile.sdk
|
|
|
|
If you would like to have a git management for the source code move to
|
|
to section 4 [Management of TF-A source code with GIT].
|
|
|
|
Otherwise, to manage TF-A source code without git, you must extract the
|
|
tarball now and apply the patch:
|
|
|
|
$> tar xf ##BP##-##PR##.tar.xz
|
|
$> cd ##BP##
|
|
$> for p in `ls -1 ../*.patch`; do patch -p1 < $p; done
|
|
|
|
You can now move to section 5 [Compile TF-A source code].
|
|
|
|
-----------------------------------
|
|
4. Manage TF-A source code with GIT
|
|
-----------------------------------
|
|
If you like to have a better management of change made on TF-A source, you
|
|
have 3 solutions to use git:
|
|
|
|
4.1 Get STMicroelectronics TF-A source from GitHub
|
|
--------------------------------------------------
|
|
URL: https://github.com/STMicroelectronics/arm-trusted-firmware.git
|
|
Branch: ##ARCHIVER_ST_BRANCH##
|
|
Revision: ##ARCHIVER_ST_REVISION##
|
|
|
|
$ git clone https://github.com/STMicroelectronics/arm-trusted-firmware.git
|
|
$ git checkout -b WORKING ##ARCHIVER_ST_REVISION##
|
|
|
|
4.2 Create Git from tarball
|
|
---------------------------
|
|
$ cd <directory to tf-a source code>
|
|
$ test -d .git || git init . && git add . && git commit -m "tf-a source code" && git gc
|
|
$ git checkout -b WORKING
|
|
$ for p in `ls -1 ../*.patch`; do git am $p; done
|
|
|
|
4.3 Get Git from Arm Software community and apply STMicroelectronics patches
|
|
---------------------------------------------------------------
|
|
URL: git://github.com/ARM-software/arm-trusted-firmware.git
|
|
Branch: ##ARCHIVER_COMMUNITY_BRANCH##
|
|
Revision: ##ARCHIVER_COMMUNITY_REVISION##
|
|
|
|
$ git clone git://github.com/ARM-software/arm-trusted-firmware.git
|
|
$ cd arm-trusted-firmware
|
|
$ git checkout -b WORKING ##ARCHIVER_COMMUNITY_REVISION##
|
|
$ for p in `ls -1 <path to patch>/*.patch`; do git am $p; done
|
|
|
|
---------------------------
|
|
5. Compile TF-A source code
|
|
---------------------------
|
|
Since OpenSTLinux activates FIP by default, FIP_artifacts directory path must be specified before launching compilation
|
|
- In case of using SOURCES-xxxx.tar.gz of Developer package the FIP_DEPLOYDIR_ROOT must be set as below:
|
|
$> export FIP_DEPLOYDIR_ROOT=$PWD/../../FIP_artifacts
|
|
|
|
To compile TF-A source code
|
|
$> make -f $PWD/../Makefile.sdk all
|
|
or for a specific config :
|
|
$ make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157c-ev1 TF_A_CONFIG=trusted ELF_DEBUG_ENABLE='1' all
|
|
|
|
NB: TF_A_DEVICETREE flag must be set to switch to correct board configuration.
|
|
|
|
By default, the build results for this component are available in $PWD/../deploy directory.
|
|
If needed, this deploy directory can be specified by added "DEPLOYDIR=<your_deploy_dir_path>" compilation option to the build command line above.
|
|
In case DEPLOYDIR=$FIP_DEPLOYDIR_ROOT/arm-trusted-firmware it overwrites files directly in FIP artifacts directory.
|
|
|
|
The generated FIP images are available in $FIP_DEPLOYDIR_ROOT/fip
|
|
|
|
---------------------------
|
|
6. Update software on board
|
|
---------------------------
|
|
Please use STM32CubeProgrammer then only tick the boot partitions means patitions 0x1 to 0x6 (more informations on the wiki website http://wiki.st.com/stm32mpu)
