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.
