This article is a guideline to OP-TEE trusted application support, which is fully integrated from release 1.7.1.21_MP13-A1 of STM32CubeIDE.
It proposes creating one OP-TEE trusted application project to implement:
- user space hello world with call to OP-TEE trusted application
- OP-TEE trusted application itself with UUID support
1. Prerequisites[edit source]
Minimum hardware
- STM32MP135F-DK-based board
- Linux console
- Ethernet (or Ethernet over USB) for connection to Linux® Cortex®-A
Minimum software
- STM32CubeIDE v1.7.1.21_MP13-A1 installed and
- STM32MP15 project created
- Yocto SDK installed thanks to "Setup OpenSTLinux", root project contextual menu
- Linux project imported thanks to "Import an OpenSTLinux project", root project contextual menu
Yocto SDK is required to built trusted application example and Linux project is used here only to deploy trusted application on the STM32MP13 target.
2. STM32CubeIDE Linux user space[edit source]
From STM32CubeIDE release 1.6.0 it is possible to enrich an STM32MP15x hierarchical project with User Space type project.
- executable project support - myExe
- static library project support - myStaticLib
- shared library project support - mySharedLib
- GTK library usage example - GtkHelloWorld
3. Eclipse CDT STM32 Linux user space[edit source]
From STM32CubeIDE release 1.6.0 it is also possible to easily create a STM32MP15x user space project from standard CDT Eclipse wizard.
In that case, the user space project is not part of any STM32MP15x hierarchical project and appears as a standalone project in Eclipse project explorer view: myCdtProject here after:
- STM32MP15x Linux user space executable from CDT wizard project support - myCdtProject
