The branch main of this GitHub repository contains the CMSIS-Zone Utility that supports the multi-step approach for splitting complex multi-core systems into sub-systems. The CMSIS-Zone documentation is available under https://arm-software.github.io/CMSIS-Zone
CMSIS-Zone is flexible and supports multiple use-cases, for example the setup of MPU (memory protection unit) or TrustZone. It implements the infra-structure that is required for:
- Split of a multi-processor system for single processor views and secure/non-secure views
- TrustZone setup (SAU, Interrupt assignment to Secure/Non-Secure)
- Setup of device specific Memory Protection Controller (MPC)
- Setup of device specific Peripheral Protection Controller (PPC)
- Setup of Memory Protection Unit (MPU)
- Generation of linker scatter files.
The source code of the CMSIS-Zone is released under open source license and part of cmsis-pack-eclipse.
Use Issues to provide feedback and report problems for the CMSIS-Zone Utility and the CMSIS-Zone project examples.
Note: The branch develop of this GitHub repository reflects our current state of example projects and is constantly updated. It allows you to review the work and provide feedback or create pull requests for contributions.
For further details see also the Slides of the Embedded World CMSIS Partner Meeting.
The installation of CMSIS-Zone is described here https://arm-software.github.io/CMSIS_5/Zone/html/zTInstall.html.
For first steps refer to:
- Configuring Armv8-M systems with CMSIS-Zone - this blog contains a video (at the end) that shows how to operate the CMSIS-Zone utility
- CMSIS-Zone Utility - Examples - the documentation contains examples for different hardware platforms. To get started with a new hardware platform a *.rzone system resource file is required.
