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. ### Timeline - 2021-01-29: docs.rs lists 1.0.0 and 1.1.0 releases. - 2024-01-07: docs.rs lists 2.0.0. - 2025-10-06: docs.rs lists 2.2.0. - 2026 batch: Input metadata shows Homebrew, Nix, and pacman packages. ### Related projects - Raspberry Pi's elf2uf2 is credited by the official README as the basis for elf2uf2-rs. - Cargo is part of the documented install and project-runner workflow. ### Sources - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
