Expel

An ESP32 (Xtensa) ELF Loader.

It allows you to load and execute ELF binaries from your Rust-based ESP-HAL (no_std) firmware.

To compile compatible programs, build them as relocatable objects (-Wl,-r flag). This can be done in the .cargo/config.toml file if using Rust or directly as a flag in your C compiler.
