m33mu – Cortex-M33 emulator

m33mu is an emulator for ARMv8-M Cortex-M33 microcontrollers with TrustZone awareness. It is designed to emulate Cortex-M targets with support for secure and non-secure execution, debugging, interrupt handling, and memory-mapped peripherals.

The project is aimed at firmware development, testing, and experimentation for modern Cortex-M33 systems, including supported targets from STMicroelectronics, NXP, Nordic Semiconductor, and Raspberry Pi.

This is free and open source software.

Key Features

  • Emulates ARMv8-M baseline Cortex-M33 targets.
  • Supports TrustZone security extensions.
  • Provides secure and non-secure world switching.
  • Includes a GDB remote server for debugging.
  • Supports interrupt handling with NVIC-like behaviour.
  • Implements memory protection unit and security attribution unit support.
  • Uses a pluggable MMIO bus for peripheral emulation.
  • Supports UART, SPI flash, and TPM-related peripheral functionality.
  • Includes an interactive text user interface option.
  • Supports multiple emulated microcontroller targets including STM32, NXP, Nordic, and RP2350 devices.
