make ARCH=x86_64 run
# loongarch64
make ARCH=loongarch64 run

Run with build tool.

# riscv64
byteos build byteos.toml riscv64-qemu
# aarch64
byteos build byteos.toml aarch64-qemu
# x86_64
byteos build byteos.toml x86_64-qemu
# loongarch64
byteos build byteos.toml loongarch64-qemu

You can find available modules using the following command.
