Article purpose
This article aims at proposing a way to organize, on the host PC, the software packages of the different Packages (Starter, Developer and Distribution) for a given release of the STM32MPU Embedded Software distribution.
The main objective of the proposed organization is to keep together the software packages corresponding to a given release because there are links between them. For example:
- Flashing the image from the Starter Package on the board is mandatory before modifying the source code from the Developer Package. Both the image and the source code must belong to the same software release.
- The SDK (Developer Package) and the image (Starter Package) have both been generated from the Distribution Package. A software release thus guarantees that there is no misalignment between the different software packages.
 |
The objective of this article is to describe one organization among all the possible organizations. Feel free to organize the delivered Packages in any other way that would better match your way of working. |
|
In practice, this article uses the release STM32MP15-Ecosystem-v2.0.0 for the STM32MPU Embedded Software distribution as an example to illustrate the proposed organization. If you are using a different release, the names of the directories and files might differ. |
The directories are shown in green, while the files are in black.
Creating the structure
- Create your <working directory> and assign a unique name to it (for example by including the release name):
PC $> mkdir STM32MP15-Ecosystem-v2.0.0 PC $> cd STM32MP15-Ecosystem-v2.0.0
- Create the first-level directories that will host the software packages delivered through the STM32MPU Embedded Software distribution release note:
PC $> mkdir Starter-Package PC $> mkdir Developer-Package PC $> mkdir Distribution-Package
- The resulting directory structure looks as follows:
STM32MP15-Ecosystem-v2.0.0 STM32MPU Embedded Software release ├── Developer-Package Developer Package installation directory ├── Distribution-Package Distribution Package installation directory └── Starter-Package Starter Package installation directory
Once all software packages have been installed according to the instructions given in the STM32MPU Embedded Software distribution release note, the resulting directory structure looks as follows:
STM32MP15-Ecosystem-v2.0.0 STM32MPU Embedded Software release ├── Developer-Package Developer Package installation directory │ ├── SDK SDK for OpenSTLinux distribution │ ├── {{#vardefine:name|}}{{#vardefine:url|}}{{#vardefine:path|}}{{#vardefine:name|en.stm32cubemp1_v1-2-0.zip}}{{#vardefine:url|https://www.st.com/content/ccc/resource/technical/software/firmware/group0/a8/dd/fb/ea/20/e5/4d/4d/stm32cubemp1_v1-2-0/files/stm32cubemp1_v1-2-0.zip/jcr:content/translations}}{{#vardefine:path%7CSTM32Cube_FW_MP1_V1.2.0}}{{#var:path}} STM32CubeMP1 Package │ └── stm32mp1-{{#vardefine:name|}}{{#vardefine:url|}}{{#vardefine:path|}}{{#vardefine:name|openstlinux-5.4-dunfell-mp1-20-06-24}}{{#vardefine:url|https://github.com/STMicroelectronics/oe-manifest.git}}{{#vardefine:path%7C}}{{#var:name}} Linux kernel, U-Boot, TF-A and OP-TEE OS source code (OpenSTLinux distribution) ├── Distribution-Package Distribution Package installation directory │ └── stm32mp1-{{#vardefine:name|}}{{#vardefine:url|}}{{#vardefine:path|}}{{#vardefine:name|openstlinux-5.4-dunfell-mp1-20-06-24}}{{#vardefine:url|https://github.com/STMicroelectronics/oe-manifest.git}}{{#vardefine:path%7C}}{{#var:name}} OpenSTLinux distribution (full source code and OpenEmbedded-based build framework) └── Starter-Package Starter Package installation directory └── stm32mp1-{{#vardefine:name|}}{{#vardefine:url|}}{{#vardefine:path|}}{{#vardefine:name|openstlinux-5.4-dunfell-mp1-20-06-24}}{{#vardefine:url|https://github.com/STMicroelectronics/oe-manifest.git}}{{#vardefine:path%7C}}{{#var:name}} Software image (binaries)
Focus on the Starter Package directory
The Starter-Package directory contains the software image for the STM32MPU Embedded Software distribution.
The trusted boot chain is the default solution delivered by STMicroelectronics. It includes the superset of features (for example, all Flash memory devices are supported). The basic boot chain is also upstreamed by STMicroelectronics, with a limited number of features (for example microSD card memory boot only). Refer to the Boot chain overview article for details.
Flash memory partitions (e.g. rootfs, bootfs...) are explained in the STM32MP15 Flash mapping article.

Appendix B shows the structure of the build directory.
Appendix A: directory structure after build (Developer Package)
Provided you have followed the recommendations of the README.HOW_TO.txt helper files to build the Linux kernel, the U-Boot and the TF-A, then the following new directories and files contain the build outputs.

Appendix B: directory structure after build (Distribution Package)
Provided you have followed the build method explained in OpenSTLinux distribution, then the following new directories contain the build outputs.
As long as you did not modify the source code:
- the 模板:STPurple are the same as the ones available in the Starter Package: flash layout, binaries for bootfs, rootfs, userfs and vendorfs partitions
- the files in grey are the same as the ones available in the Starter and Developer Packages: binaries for FSBL and SSBL partitions, and for OP-TEE OS runtime services
- the 模板:Orange are the same as the ones available in the Developer Package: Linux kernel image and device tree blobs, and debug symbol files
