1 Overview[edit]

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]

2.1 Install extra packages[edit]

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-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev pylint3 pylint xterm
 sudo apt-get install make xsltproc docbook-utils fop dblatex xmlto
 sudo apt-get install libmpc-dev libgmp-dev
  • Packages needed for some "Developer Package" use cases:
 sudo apt-get install libncurses5 libncurses5-dev libncursesw5-dev libssl-dev linux-headers-generic u-boot-tools device-tree-compiler bison flex g++ libyaml-dev libmpc-dev libgmp-dev
  • Package for repo (used to download the "Distribution Package" source code):
Please follow the installation instructions described in repo.
 For Ubuntu 20.04, first sets python3 as default:  sudo apt install python-is-python3
  • 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 diffstat libxml2-utils


2.2 Additional configurations[edit]

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]

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

Warning white.png Warning
To download a package, it is recommended to be logged in to your "myst" account [1]. If, trying to download, you encounter a “403 error”, you could try to empty your browser cache to workaround the problem. We are working on the resolution of this problem.
We apologize for this inconvenience

For ecosystem release v3.1.0 More info.png :

  • Download the Developer Package SDK 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-5.10-dunfell-mp1-21-11-17.tar.xz

For ecosystem release v3.0.0 More info.png :

  • Download the Developer Package SDK 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-5.10-dunfell-mp1-21-03-31.tar.xz

4 Run the SDK installation script[edit]

For ecosystem release v3.1.0 More info.png :

  • Create your STM32MP15 Developer Package SDK directory on your host computer
 mkdir -p $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v3.1.0/Developer-Package/SDK
  • Change the permissions of the SDK installation script so that it is executable
 chmod +x stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17/sdk/st-image-weston-openstlinux-weston-stm32mp1-x86_64-toolchain-3.1.11-openstlinux-5.10-dunfell-mp1-21-11-17.sh
  • Execute the SDK installation script
 ./stm32mp1-openstlinux-5.10-dunfell-mp1-21-11-17/sdk/st-image-weston-openstlinux-weston-stm32mp1-x86_64-toolchain-3.1.11-openstlinux-5.10-dunfell-mp1-21-11-17.sh -d <working directory absolute path>/Developer-Package/SDK
  • The following log is output when the installation is successful:

5 Start the SDK up[edit]

Info white.png Information
The SDK environment setup script must be run once on each new working terminal on which you cross-compile

For ecosystem release v3.1.0 More info.png :

 cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v3.1.0/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
arm
  • Check the toolchain binary prefix for the target tools
 echo $CROSS_COMPILE
arm-ostl-linux-gnueabi-

  • Check the C compiler version
 $CC --version
arm-ostl-linux-gnueabi-gcc (GCC) 9.3.0

  • Check that the SDK version is the expected one
 echo $OECORE_SDK_VERSION

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