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

获取源码并编译 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="-mcpu=thead-c906" compile

正常情况下，终端会看到类似如下输出：

«Ruyi venv-gnu-plct» debian@duos-1cae:~$ cd coremark

运行 coremark

./coremark.exe

正常情况下，终端会看到类似如下输出：

返回上级目录并退出 ruyi LLVM 虚拟环境

cd ..; ruyi-deactivate

Coremark（LLVM）

创建并激活 ruyi 虚拟环境（LLVM）

ruyi venv -t toolchain/llvm-plct manual --sysroot-from gnu-plct venv-llvm-plct

. ~/venv-llvm-plct/bin/ruyi-activate

验证 LLVM 版本

clang -v

编译 coremark（LLVM）

cd coremark; make clean; make CC=clang XCFLAGS="-march=rv64imafdc_xtheadba_xtheadbb_xtheadbs_xtheadcmo_\
xtheadcondmov_xtheadfmemidx_xtheadmac_xtheadmemidx_xtheadmempair_xtheadsync" compile
