The OpenSTLinux distribution encompasses the following components:
- The OpenSTLinux BSP that offers services, to the application frameworks in the same context, from:
- The boot chain based on TF-A and U-Boot
- The OP-TEE secure OS running on the Cortex-A in secure mode
- The Linux® kernel running on the Arm® Cortex®-A in non-secure mode
- The Application frameworks that rely on the services provided by the OpenSTLinux BSP, to provide particular functionalities (code libraries, APIs, tool sets...) to facilitate the development of software applications:
- The Linux application frameworks (aka Linux middlewares) running on the user space of the Linux OS: e.g. libusb C library for a generic access to USB devices, ALSA user-space bundle for audio functionalities, GStreamer multimedia framework...
- The OPU-TEE Boot application frameworks running on the user space of the secure OS (not shown in the diagram), as part of the boot chain: e.g. TEE Internal core API for the development of configuration scripts
- On OP-TEE side, the Trusted Applications (TA)The U-Boot application frameworks: e.g. configuration scripts relies on the OP-TEE core for secrets operations (not visible from the Linux and STM32Cube MPU Package)
