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.
