MCUboot is a secure bootloader for 32-bit MCUs. It defines a common infrastructure for the bootloader, defines system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software updates. MCUboot combines an independent operating system and hardware, relying on hardware porting layers from the operating system it works with. The Flexible Software Package (FSP) integrates an MCUboot port starting from FSP v3.0.0.

MCUboot provides a secure bootloader infrastructure for 32-bit MCUs, enabling secure booting and fail-safe application updates. It supports multiple update strategies—Overwrite, Swap, and Direct Execute-In-Place (DXIP)—each with distinct advantages and memory requirements. The bootloader authenticates firmware images using RSA or ECDSA signatures and SHA-256 hashing. Integration with Renesas Flexible Software Package (FSP) allows easy MCUboot deployment across RA Family MCUs, supporting TrustZone-based security. Example projects demonstrate multi-image and single-image configurations on EK-RA6M4 and EK-RA6M3 kits. The document guides hardware setup, software configuration, project creation, signing, and debugging to implement secure bootloader solutions.

Arm® TrustZone® technology divides RA Family microcontrollers into Secure and Non-Secure partitions, enabling secure application development by isolating memory and resources. Secure code accesses both partitions, while Non-Secure code accesses Secure resources only through Non-Secure Callable (NSC) gateways. Development involves creating separate Secure and Non-Secure projects or a Flat project without TrustZone. The RA Project Generator simplifies project setup, managing security attributes, peripheral access, and debugging configurations. Secure code initializes critical functions and controls access, while Non-Secure code interacts via guarded NSC drivers. The document details workflows, memory partitioning, calling conventions, and tooling support for efficient TrustZone implementation.
