How to Use Rust for RISC-V Development

Install the RISC-V target using rustup and compile your code with the --target flag.

1. Add the RISC-V target to your toolchain. rustup target add riscv64gc-unknown-none-elf

2. Compile your project for the RISC-V architecture. cargo build --target riscv64gc-unknown-none-elf

3. Run tests for the target if a simulator is available. cargo test --target riscv64gc-unknown-none-elf

Note: The riscv64im-unknown-none-elf target is also available as a tier 3 option in Rust 1.94.0.

You need to tell Rust to generate code for the RISC-V processor instead of your computer's CPU. This is done by installing a specific 'target' profile and telling the build tool to use it. Think of it like installing a specific language pack before translating a book.
