STM32MPU Distribution Package - OpenSTLinux distribution

Applicable for

STM32MP13x lines, STM32MP15x lines, Unknown MPU, STM32MP25x lines

This article aims to give the following information:

How to download and install the latest OpenSTLinux distribution for the STM32 microprocessors series
Where to find the associated release note
Where to find the previous releases (archives)

Warning

For more specific information, go through the Distribution Package article relative to your STM32 microprocessors series: Category:Distribution Package

1. STM32MPU-Ecosystem-v6.0.0 release[edit | edit source]

The STM32MPU OpenSTLinux distribution is delivered through a manifest repository location and a manifest revision.
The installation relies on the repo command. In case the Repo tool (a Google-built repository management tool that runs on top of git) is not yet installed and configured on the host PC, refer to the PC prerequisites article.
The OpenSTLinux distribution is massively using open source software (OSS) packages that are downloaded from a variety of open source repositories; so it is required that the IT infrastructure proxies do not forbid such accesses. If some proxy-related issues are suspected, refer to the How to avoid proxy issues article.
Install the STM32MPU OpenSTLinux distribution: unknown revision

Important

Yocto is using absolute directory path to give names to intermediate files. If the path is too long, Yocto build fails because file names exceed the maximum size supported by the file system. In that case, installation directory path should be renamed to reduce the overall absolute path name.

STM32MPU Distribution Package OpenSTLinux distribution - STM32MPU-Ecosystem-6.0.0 release

Installation

Go to the host PC directory where to install the Distribution Package (<Distribution Package installation directory>). Example, if following the proposition to organize the working directory:

cd <working directory path>/Distribution-Package

Initialize repo in the current directory (More details on 'repo init' here).

repo init -u unknown revision -b refs/tags/unknown revision

Note: "ERROR 404" may appear during "repo init" command without any impact on the process

Synchronize the local project directories with the remote repositories specified in the manifest (more details on 'repo sync' here)

repo sync

Note: Distribution package needs around 140MB to be installed (and around 25GB once distribution package is compiled).

Release note

Details about the content of this software package are available in the associated STM32 MPU ecosystem release note.

If interested in previous releases, go through the archives of the ecosystem release note.

When installed, the OpenSTLinux Distribution Package is available with following tree structure:
