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.

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.
