MabezDev/xtensa-rust-quickstart
A demo crate for the xtensa uC's (ESP32, ESP8266)
A bare-metal Rust quickstart for ESP32 and ESP8266 using the Xtensa architecture. It predates the official esp-rs ecosystem maturing and is now explicitly abandoned by its own author — the README opens with a deprecation notice pointing to the successor projects.
The repo served its purpose as an early proof-of-concept that Rust on Xtensa was even possible. The dual Apache/MIT licensing is clean. The espflash integration was ahead of its time when this was written.
Dead since April 2022 — the maintainer's own README tells you to go elsewhere. Requires a forked Rust compiler that may no longer track upstream. The two examples (esp32.rs, esp8266.rs) and a main.rs are the entire codebase; there is nothing here you can't find in a better state in esp-rs/esp-template today. Anyone who clones this instead of the successor repos is just giving themselves outdated toolchain problems.
