The codebase attempts to follow MISRA-2012 rules to the extent detailed in doc/code_rules.md.
The maintainers are gradually introducing tools in the attempt to improve the overall robustness of the codebase. Since v.2.10, Unit Testing has been introduced on a module-level. The final aim is to run unit tests for any new modules and any new additions to modules. To allow contributors to some time to familiarise with the tool and to avoid imposing additional efforts out-of-the-blue, in this release we ask contributors to provide basic unit tests for new modules and new additions. This can be done by adding unit tests on the same patches adding new features or in separate patches, but need to be within the same PR. For work that is already in the RFC in PR, we may make an exception to the request. We foresee that once the unit test framework support is consolidated, it will be possible to contribute to the project only if unit test is also included in the contributions.
-

-
Module-based architecture with an event-driven execution model:
- Firmware code is organized into modules, where a module fulfills a well- defined role (driver HAL, driver, protocol or service).
- A framework drives the initialization, orchestration of, and interactions between modules.
-
Processor-agnostic module code enables firmware portability across systems:
- Processor-dependent features (e.g. interrupt handling) are abstracted from the modules by the framework.
- The framework relies on an interface whose implementation is processor- dependent to provide these features.
-
Module configurability easing the re-use of modules on different platforms:
- Strict split between the hardware and software feature configuration data and module code.
-
A native framework test suite provides rapid development and validation of the core framework implementation.
-
Support for Armv7-M control processor architecture based on CMSIS v5 and Keil RTX 5.
-
Provides system initialization support to enable boot of the application cores.
-
Provides the following runtime services:
- Power domain management
- System power management
- Performance domain management (Dynamic voltage and frequency scaling)
- Clock management
- Sensor management
-
Provides a reference implementation of the System Control and Management Interface v1.0 (SCMI, platform-side). The SCMI specification can be found here.
-
Provides a build system supporting:
- The GNU Arm Embedded and Arm Compiler 6 toolchains
- Platforms with multiple firmware images
-
In-source Doxygen documentation
-
Support for the SGM-775 platform
- The Juno platform is extremely limited with regards to available memory. As a result the debug experience is poor, and the ability to add new features severely restricted.
- arm-compiler-6 does not support LTO with our build system. No runs can be done when the SCP-firmware is built with arm-compiler-6 due to space limitations.
