CMSIS-Zone

CMSIS-Zone is an open source utility that helps to manage software configurations for partitions that have different access permissions to system resources in devices with Arm Cortex-M processors. It implements the infrastructure that is required for:

- Split of a multi-processor system for single processor views
- TrustZone setup (SAU, Interrupt assignment to Secure/Non-Secure)
- Setup of Memory Protection Unit (MPU)
- Setup of device specific Memory Protection Controller (MPC)
- Setup of device specific Peripheral Protection Controller (PPC)

# Acess to CMSIS-Zone

CMSIS-Zone is maintained in a GitHub repository and is released as a standalone Eclipse plugin.

- CMSIS-Zone GitHub Repo contains examples, templates and documentation.
- CMSIS-Pack Eclipse Plug-ins implement the CMSIS-Zone utility.
- CMSIS-Zone Documentation explains in details how to use the CMSIS-Zone in a project.

# Key Features and Benefits

- CMSIS-Zone reduces the complexity of configuring access permissions in embedded software.
- Allows to setup of access permissions to memory and peripherals in secure/non-secure modes, and privilege execution levels.
- Provides graphical (GUI) and command line (CLI) interfaces.
- Generates the code for the setup of protection hardware such as SAU, MPC, PPC, MPU.
- Generates the linker scripts for the defined partitions.
- Includes multiple examples for real hardware.
