This advanced real-time operating system (RTOS) is designed specifically for deeply embedded applications. Among the multiple benefits it provides are advanced scheduling facilities, message passing, interrupt management, and messaging services. Azure RTOS ThreadX has many advanced features, including picokernel architecture, preemption threshold, event chaining, and a rich set of system services.
Documentation for this library can be found here: http://docs.microsoft.com/azure/rtos/threadx
The main components of Azure RTOS are each provided in their own repository, but there are dependencies between them--shown in the following graph--that are important to understand when setting up your builds.
Install the following tools:
- CMake version 3.0 or later
- GCC compilers for arm-none-eabi
- Ninja
$ git clone https://github.com/azure-rtos/threadx.gitEach component of Azure RTOS comes with a composable CMake-based build system that supports many different MCUs and host systems. Integrating any of these components into your device app code is as simple as adding a git submodule and then including it in your build using the CMake command add_subdirectory().
While the typical usage pattern is to include threadx into your device code source tree to be built & linked with your code, you can compile this project as a standalone static library to confirm your build is set up correctly.
$ cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_m4.cmake -GNinja .
$ cmake --build ./buildNOTE: You will have to take the dependency graph above into account when building anything other than threadx itself.
The master branch has the most recent code with all new features and bug fixes. It does not represent the latest General Availability (GA) release of the library.
Each official release (preview or GA) will be tagged to mark the commit and push it into the Github releases tab, e.g. v6.0-rel.

Azure RTOS provides OEMs with components to secure communication and to create code and data isolation using underlying MCU/MPU hardware protection mechanisms. It is ultimately the responsibility of the device builder to ensure the device fully meets the evolving security requirements associated with its specific use case.
