1. Overview[edit source]

This stage explains how to install the SDK.
The SDK for OpenSTLinux distribution provides a standalone cross-development toolchain and libraries tailored to the contents of the specific image flashed onto the board.

2. Host computer configuration[edit source]

2.1. Install extra packages[edit source]

Additional Ubuntu packages must be installed to perform basic development tasks, basic cross-compilation (via Developer Package) or more complex cross-compilation such as OpenEmbedded does (via Distribution Package):

Packages required by OpenEmbedded/Yocto (details here):

sudo apt-get update
sudo apt-get install gawk wget git diffstat unzip texinfo gcc-multilib  chrpath socat cpio python3 python3-pip python3-pexpect 
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint xterm bsdmainutils
sudo apt-get install libssl-dev libgmp-dev libmpc-dev lz4 zstd

Packages needed for some "Developer Package" use cases:

sudo apt-get install build-essential libncurses-dev libncurses5 libyaml-dev libssl-dev

Package for repo (used to download the "Distribution Package" source code):

First set python3 as default: sudo apt install python-is-python3

Then follow the installation instructions described in repo.

Useful tools:

sudo apt-get install coreutils bsdmainutils sed curl bc lrzsz corkscrew cvs subversion mercurial nfs-common nfs-kernel-server libarchive-zip-perl dos2unix texi2html libxml2-utils

2.2. Additional configurations[edit source]

Additional configurations have to be installed to support up to 16 partitions per MMC. By default, on Linux^® systems, a maximum of 8 partitions are allowed on MMC. All Packages (Starter Package, ...) need more than 10 partitions for the storage device. In order to extend the number of partitions per device to 16, the following options must be added to modprobe:

 echo 'options mmc_block perdev_minors=16' > /tmp/mmc_block.conf
 sudo mv /tmp/mmc_block.conf /etc/modprobe.d/mmc_block.conf

3. For STM32MP2 series[edit source]

3.1. Download the SDK and run the SDK installation script[edit source]

3.2. Start the SDK up[edit source]

Information

The SDK environment setup script must be run, once, on each new working terminal on which you cross-compile

 cd $HOME/STM32MPU_workspace/STM32MPU-Ecosystem-v5.1.0/Developer-Package 
 source SDK/environment-setup-cortexa35-ostl-linux

The following checks ensure that the environment is correctly set up:

Check the target architecture

 echo $ARCH
arm64

Check the toolchain binary prefix for the target tools

 echo $CROSS_COMPILE
aarch64-ostl-linux-

Check the C compiler version

 $CC --version
aarch64-ostl-linux-gcc (GCC) 12.3.0
Copyright (C) 2022 Free Software Foundation, Inc.

Check that the SDK version is the expected one (e.g.)

 echo $OECORE_SDK_VERSION
4.2.4-openstlinux-6.1-yocto-mickledore-mpu-v24.06.26

If any of these commands fails or does not return the expected result, try to reinstall the SDK.
