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。
安装依赖包
sudo apt update; sudo apt install -y wget tar zstd xz-utils git build-essential
安装ruyi包管理器
wget https://fast-mirror.isrc.ac.cn/ruyisdk/ruyi/tags/0.47.0/ruyi.riscv64
chmod +x ruyi-0.47.0.riscv64
sudo cp -v ruyi-0.47.0.riscv64 /usr/local/bin/ruyi
安装GCC和LLVM工具链
ruyi update
ruyi install gnu-plct llvm-plct
Coremark（GCC）
创建并激活 ruyi 虚拟环境（GCC）
ruyi venv -t toolchain/gnu-plct manual venv-gnu-plct
. ~/venv-gnu-plct/bin/ruyi-activate
验证 GCC 版本
riscv64-plct-linux-gnu-gcc -v
编译并运行 coremark
git clone https://github.com/eembc/coremark
#若无法访问GitHub，使用Gitee镜像替代
#git clone https://gitee.com/mirrors_eembc/coremark
cd coremark
make CC=riscv64-plct-linux-gnu-gcc
XCFLAGS="-march=rv64imafdcv_zicbom_zicboz_zicntr_zicond_zicsr_zifencei_zihintpause_zihpm_zfh_zfhmin_zca_zcd_zba_zbb_zbc_zbs_zkt_zve32f_zve32x_zve64d\

./coremark.exe
正常情况下，终端会看到类似如下输出：
