Summary

This 2021 blog by Steve Branam surveys using Rust for embedded firmware, documenting motivations, initial learning resources, and practical considerations for adoption. Readers will learn what Rust brings to no_std/bare-metal development and how it fits into ARM Cortex-M and RISC-V embedded workflows.

Key Takeaways

• Assess Rust's suitability for embedded projects by weighing safety benefits against toolchain and ecosystem maturity
• Set up a Rust embedded toolchain and cross-compile for no_std targets like ARM Cortex-M and RISC-V
• Apply no_std patterns and use crates such as embedded-hal and RTIC for peripheral and concurrency abstractions
• Identify migration risks from existing C/C++ code including FFI, build/test changes, and interrupt/ISR safety

Who Should Read This

Intermediate embedded firmware engineers or technical leads familiar with MCU development in C/C++ who want to evaluate or adopt Rust for safer, no_std firmware on ARM or RISC-V platforms.
