This article describes how to get and use the Developer Package of the STM32MPU Embedded Software for any development platform of the STM32MP1 series (STM32MP15 boards and STM32MP13 boards) and STM32MP2 series (STM32MP23 boards and STM32MP25 boards), in order to modify some of its pieces of software, or to add applications on top of it.
It lists some prerequisites in terms of knowledge and development environment, and gives the step-by-step approach to download and install the STM32MPU Embedded Software components for this Package.
Finally, it proposes some guidelines to upgrade (add, remove, configure, improve...) any piece of software.
1. Developer Package content[edit | edit source]
If you are not yet familiar with the STM32MPU Embedded Software distribution and its Packages, read the following articles:
- Which STM32MPU Embedded Software Package better suits your needs (and especially the Developer Package chapter)
- STM32MPU Embedded Software distribution
If you are already familiar with the Developer Package for the STM32MPU Embedded Software distribution, the fast links to essential commands might interest you.
To sum up, this Developer Package provides:
- for the OpenSTLinux distribution (development on Arm® Cortex®-A processor):
- the software development kit (SDK), based on Yocto SDK, for cross-development on a host PC
- the following pieces of software in source code:
- Linux® kernel
- gcnano-driver
- U-Boot
- Trusted Firmware-A (TF-A)
- Open source Trusted Execution Environment (OP-TEE)
- External device tree (for STM32MP2 series only)
- for the Cortex®-M processor firmware development (only for STM32MP15x lines
and STM32MP2 series):
- the integrated development environment (IDE) (STM32CubeIDE)
- the STM32CubeMPU Package including all pieces of software (BSP, HAL, middlewares, and applications) in source code
- the Trusted Firmware-M (TF-M) in source code (for STM32MP2 series only)
- the debug symbol files for Linux® kernel, U-Boot, TF-A, OP-TEE, and TF-M (for STM32MP2 series only)
Note that the application frameworks for the OpenSTLinux distribution are not available as source code in this Package.
TF-M is available only for STM32MP2 series
2. Developer Package step-by-step overview[edit | edit source]
The steps to get the STM32MPU Embedded Software Developer Package ready for your developments are:
☐ Checking the prerequisites
☐ Installing the Starter Package for your board
☐ Installing the components to develop software running on Arm® Cortex®-A (OpenSTLinux distribution)
- ☐ Installing the SDK (mandatory for any development on Arm® Cortex®-A)
- ☐ Installing the OpenSTLinux BSP package (mandatory only if you plan to modify the Linux kernel, to add external out-of-tree Linux kernel modules, to modify U-Boot, TF-A, OP-TEE OS)
- ☐ Installing the debug symbol files (mandatory only if you plan to debug Linux® kernel, U-Boot, OP-TEE, or TF-A with GDB)
☐ Installing the components to develop software running Arm Cortex-M (STM32CubeMPU Package)
- ☐ Installing STM32CubeIDE (mandatory for any development on Arm® Cortex®-M)
- ☐ Installing the STM32CubeMPU Package (mandatory only if you plan to modify the STM32Cube firmware)
Once these steps are achieved, you are able to:
- develop software running on Arm Cortex-A
- develop software running on Arm Cortex-M (only on STM32MP15x lines and STM32MP2 series)
3. Checking the prerequisites[edit | edit source]
3.1. Knowledge[edit | edit source]
The STM32MPU Developer Package aims at enriching a Linux-based software for the targeted product: basic knowledge about Linux are recommended to make the most of this Package.
Having a look at the STM32MPU Embedded Software architecture overview is also highly recommended.
3.2. Development setup[edit | edit source]
The recommended setup for the development PC (host) is specified in the following article: PC prerequisites.
Whatever the development platform (board) and development PC (host) used, the range of possible development setups is illustrated by the picture below.
The following components are mandatory:
- Host PC for cross-compilation and cross-debugging, installed as specified above
- Board assembled and configured as specified in the associated Starter Package article
- Mass storage device (for example, microSD card) to load and update the software images (binaries)
The following components are optional, but recommended:
- A serial link between the host PC (through Terminal program) and the board for traces (even early boot traces), and access to the board from the remote PC (command lines)
- An Ethernet link between the host PC and the board for cross-development and cross-debugging through a local network. This is an alternative or a complement to the serial (or USB) link
- A display connected to the board, depending on the technologies available on the board: DSI LCD display, HDMI monitor (or TV) and so on
- A mouse and a keyboard connected through USB ports
Additional optional components can be added by means of the connectivity capabilities of the board: cameras, displays, JTAG, sensors, actuators, and much more.
4. Installing the Starter Package[edit | edit source]
Before developing with the Developer Package, it is essential to start up your board thanks to its Starter Package. All articles relative to Starter Packages are found in Category:Starter Package: find the one that corresponds to your board, and follow the installation instructions (if not yet done), before going further.
In brief, it means that:
- your board boots successfully
- the flashed image comes from the same release of the STM32MPU Embedded Software distribution as the components that will be downloaded in this article
Thanks to the Starter Package, all Flash partitions are populated.
Then, with the Developer Package, it is possible to modify or to upgrade the partitions independently one from the others.
For example, if you only want to modify the Linux kernel (part of bootfs partition), installing the SDK and the Linux kernel are enough; no need to install anything else.
5. Installing the components to develop software running on Arm Cortex-A (OpenSTLinux distribution)[edit | edit source]
5.1. Installing the SDK[edit | edit source]
Optional step: it is mandatory only if you want to modify or add software running on Arm Cortex-A (for example Linux kernel, Linux user space applications...).
The SDK for OpenSTLinux distribution provides a stand-alone cross-development toolchain and libraries tailored to the contents of the specific image flashed in the board. If you want to know more about this SDK, read the SDK for OpenSTLinux distribution article.

5.1.1. Starting up the SDK[edit | edit source]
The SDK environment setup script must be run once in each new working terminal in which you cross-compile:
For STM32MP1 series
source <SDK installation directory>/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
The following checkings allow to ensure that the environment is correctly setup:
- 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) <GCC version> [...]
- Check that the SDK version is the expected one
echo $OECORE_SDK_VERSION <expected SDK version>
For STM32MP2 series
source <SDK installation directory>/environment-setup-cortexa35-ostl-linux
The following checkings allow to ensure that the environment is correctly setup:
- 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) <GCC version> [...]
- Check that the SDK version is the expected one
echo $OECORE_SDK_VERSION <expected SDK version>
If any of these commands fails or does not return the expected result, try to reinstall the SDK.
5.2. Installing the OpenSTLinux BSP packages[edit | edit source]
Optional step: it is mandatory only if you want to modify the BSP (Linux kernel, TF-A, U-Boot, OP-TEE OS), or to add external out-of-tree Linux kernel modules.

Once a suitable cross-toolchain (OpenSTLinux SDK) is installed, it is easy to develop a project outside of the OpenEmbedded build system.
There are different ways to use the SDK toolchain directly, among which Makefile and Autotools.
Whatever the method, it relies on:
- the sysroot that is associated with the cross-toolchain, and that contains the header files and libraries needed for generating binaries (see target sysroot)
- the environment variables created by the SDK environment setup script (see SDK startup)
You can refer to the following simple example:
