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):

 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 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. Download the SDK[edit source]

The software package is provided AS IS, and by downloading it, you agree to be bound to the terms of the software license agreement (SLA0048). The detailed content licenses can be found here.

  • Download the en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz file, available on, into the following directory: $HOME/STM32MPU_workspace/tmp
  • Uncompress the tarball file to get the SDK installation script
 cd $HOME/STM32MPU_workspace/tmp
 tar xvf en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21.tar.gz

4. Run the SDK installation script[edit source]

  • Create your STM32MP1 Developer Package SDK directory on your host computer
 mkdir -p $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK
  • Change the permissions of the SDK installation script so that it is executable
 chmod +x stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/sdk/
  • Execute the SDK installation script
 ./stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21/sdk/ -d <working directory absolute path>/Developer-Package/SDK
  • The following log is output when the installation is successful:
ST OpenSTLinux - Weston - (A Yocto Project Based Distro) SDK installer version 4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21
You are about to install the SDK to "/home/osboxes/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK". Proceed [Y/n]? Y
Extracting SDK........................................................................................................................................................................................done
Setting it up...done
SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /home/osboxes/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package/SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

5. Start the SDK up[edit source]

Info white.png Information
The SDK environment setup script must be run once on each new working terminal on which you cross-compile
 cd $HOME/STM32MPU_workspace/STM32MP1-Ecosystem-v5.0.0/Developer-Package 
 source SDK/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

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

  • Check the target architecture
 echo $ARCH
  • Check the toolchain binary prefix for the target tools

  • Check the C compiler version
 $CC --version
arm-ostl-linux-gnueabi-gcc (GCC) 12.2.0
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
  • Check that the SDK version is the expected one (e.g.)

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