# Using FFI to Call Assembly Functions from Rust

This is a mini-howto for people wanting to call assembly functions from their Rust code.

- assembly is not inline assembly, but a separate .s source file

- just replace mnemonics to fit your target CPU (here, three examples for armv6, aarch64 and riscv64)

Cross-compilation for Raspberry Pi 1B:  

```

rustup target add arm-unknown-linux-musleabihf  

brew install arm-linux-gnueabihf-binutils  

cargo build --target="arm-unknown-linux-musleabihf" --release

```

Linux users could replace musleabihf by gnueabihf.
