Rust Development Platform for Infineon Microcontrollers

The development of secure systems is critical for the automotive market. The Rust programming language, with its built-in support for memory-safe software development, is an important enabler for the design of mission-critical automotive software. Infineon Technologies AG  takes the first step to create a Rust ecosystem in the embedded sector. 

First up are the market-leading AURIX™ TC3xx and  TRAVEO™ T2G automotive MCUs. While TRAVEO™ uses the official Rust tool chain and Arm Cortex-M targets, a dedicated Rust compiler has been developed for AURIX by Infineon's tool partner HighTec EDV-Systeme. PSoC and AURIX TC4x support will follow in the second half of 2025.

The AURIX™ TC3xx and  TRAVEO™ T2G microcontroller product families offer a wide range of integrated hardware functions for functional safety and cybersecurity. Introducing support for Rust complements these hardware features on the software side. Peripheral access crates (PACs) for AURIX and TRAVEO are provided for native access to microcontroller peripherals. The PACs are generated with the svd2rust tool and follow the same API standard for peripheral access. PACs are complemented with code examples demonstrating the use of Rust on Infineon microcontrollers and are available in GitHub.

In the automotive industry, the integration of robust software ecosystem is crucial, as are the tools to comply with the automotive-grade standards. This ensures the reliability and performance necessary to meet the rigorous requirements of this industry.

Infineon, recognizing these needs, has worked with its Rust partners to offer a complete Rust ecosystem for AURIX. This allows AURIX customers to evaluate and to develop safety and cyber security critical applications with Rust.

The AURIX™ Rust Startup ecosystem is a collaborative effort involving Veecle, Infineon, HighTec and Bluewind aimed at supporting Rust on Infineon's AURIX™ architecture for automotive and industrial applications. The primary objective is to empower customers to seamlessly integrate Rust tasks alongside existing "C" implementations for evaluation and pre-development purposes.

The AURIX™ Rust Startup ecosystem has been designed with the following goals in mind:

• Usable: Code, examples, and tooling have been developed to minimize friction and enable productive development since day one.
• Future-proof: Integration with a safety kernel and isolation into memory-protected tasks ensure Rust can be used in critical contexts from the outset.
• Legacy Compatible: Isolation of Rust into tasks facilitate the coexistence with legacy C tasks. This enables proven code reuse, thereby avoiding costly re-implementations.

The partners of the AURIX Rust Getting Started Ecosystem providing comprehensive support services along with their products are listed below.

The novel HighTec Rust Compiler, tailored for AURIX^™ TC3xx and TC4x microcontrollers, leverages the advanced open-source LLVM technology to deliver the full range of Rust language features, including memory safety, concurrency, and interoperability, for applications with safe, secure, high-performance, and rapidly deployable requirements. learn more

he debug, trace and test tool UDE® from PLS Development Tools provides comprehensive high-level language (HLL) debugging capabilities for Rust. This includes syntax highlighting of the source code considering Rust keywords. Rust applications can be debugged and tested at HLL level with all common run control functions. UDE® can display the values of static and local variables, with support for Rust-specific data types (e.g. enumerations).

Debugging for Rust applications is supported for real target hardware and for the AURIX™ instruction set simulator TSIM.  

UDE® supports the HighTec Rust Compiler for AURIX™.

Elektrobit has integrated Rust into its EB tresos AutoCore software, enhancing productivity, safety, and cybersecurity for automotive ECU development. Rust’s memory safety features address vulnerabilities, aligning with industry standards. The solution supports seamless AUTOSAR integration, static analysis, and code generation, enabling developers to mix Rust with existing C code. Elektrobit also offers workshops to help customers adopt Rust, reducing errors and accelerating development for safer vehicles.
