history

Project history and usage

elf2uf2-rs is a Rust CLI for converting ELF firmware binaries to UF2 and deploying them to supported microcontroller boards.

Project history

The official README describes elf2uf2-rs as a tool for converting ELF binaries into UF2 format and flashing them to microcontrollers including RP2040 and RP2350 boards. It credits Raspberry Pi's elf2uf2 as the basis.

docs.rs describes the crate as a Rust port of elf2uf2 and shows that it is published as a command-line package rather than a library.

Adoption history

The docs.rs release history shows a 1.0.0 release in 2021, continued 1.x releases through 2023, a 2.0.0 release in 2024, and 2.2.0 in 2025. The input metadata shows Homebrew, Nix, and pacman packaging.

How it is used

Users run elf2uf2-rs to convert firmware to UF2 files or deploy ELF output directly to a connected board. The README also documents adding a runner command to .cargo/config.toml so cargo run can flash a microcontroller.

Why package nerds care

elf2uf2-rs is a package-manager-friendly bridge between embedded Rust builds and board flashing: a single CLI turns Cargo output into a deployable UF2 workflow without requiring users to build Raspberry Pi SDK tools separately.
