PREREQS

You will need to install the riscv64gc target using rustup as well as cargo-binutils using cargo.

  • rustup target add riscv64gc-unknown-none-elf
  • cargo install cargo-binutils

BUILDING

Edit .cargo/config to match your host's configuration. The runner will execute when you type cargo run.

Type cargo build to start the build process. Type cargo run to run using the runner provided in .cargo/config

  • cargo build --release
  • cargo run --release

  • fallocate -l 32M hdd.dsk
