Install: brew install elf2uf2-rs

About:
elf2uf2-rs is a utility that converts standard ELF binaries into the UF2 format, which is required by USB Flashing Bootloaders commonly found on microcontrollers like Raspberry Pi Pico. It enables developers to flash compiled Rust or C/C++ applications directly via a USB mass storage interface without needing specialized debug probes.

Key Features:

High-performance conversion written in Rust
Supports standard ELF to UF2 format transformation
Compatible with USB Flashing Bootloaders (UFB)
Command-line interface for automation

Use Cases:

Flashing compiled Rust firmware to Raspberry Pi Pico
Converting ELF binaries for microcontrollers using UF2 bootloaders
CI/CD pipeline integration for embedded firmware deployment

Alternatives:

elf2uf2 (Python) – Original Python implementation; Rust version offers better performance and binary size
picotool – Raspberry Pi Pico SDK tool with broader features; elf2uf2-rs is more lightweight and focused
