An operating system kernel running on RISC-V arch

How to build it

Environmental requirement

• rustup ( >=1.57.0-nightly)
• Qemu ( >=5.0.0)

Step

Build locally

cd os
cargo build --release

then we get ELF file in target/riscv64gc-unknown-none-elf/release

then we should transfer ELF file into binary file by executing

rust-objcopy --binary-architecture=riscv64 target/riscv64gc-unknown-none-elf/release/os --strip-all -O binary target/riscv64gc-unknown-none-elf/release/os.bin

finally we can run our kernel on QEMU

qemu-system-riscv64 -machine virt -nographic -bios ../bootloader/rustsbi-qemu.bin -device loader,file=target/riscv64gc-unknown-none-elf/release/os.bin,addr=0x80200000
