RuyiSDK 基础示例
可直接在开发板上进行编译和运行的示例，适合初学者快速上手。
安装ruyi包管理器
sudo apt update; sudo apt install wget
wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.49.0/ruyi-0.49.0.riscv64
chmod +x ./ruyi-0.49.0.riscv64
sudo cp -v ./ruyi-0.49.0.riscv64 /usr/local/bin/ruyi安装GCC和LLVM工具链
ruyi update
ruyi install gnu-plct llvm-plctCoremark (GCC版)
创建并激活ruyi虚拟环境（GCC）
ruyi venv --toolchain gnu-plct generic gcc-env
. gcc-env/bin/ruyi-activate验证GCC版本
riscv64-plct-linux-gnu-gcc -v编译Coremark（GCC）
git clone https://github.com/eembc/coremark
cd coremark
make CC=riscv64-linux-gcc XCFLAGS="-static -march=rv64imafdc" compile
mv coremark.exe coremark_gccPC端传输
