RuyiSDK 基础示例
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://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.47.0/ruyi-0.47.0.amd64
chmod +x ./ruyi-0.47.0.amd64
sudo cp -v ./ruyi-0.47.0.amd64 /usr/local/bin/ruyi
安装GCC和LLVM工具链
ruyi update
ruyi install gnu-plct llvm-plct
Coremark (GCC版)
创建并激活ruyi虚拟环境（GCC）
ruyi venv -t toolchain/gnu-plct generic venv-gnu-plct-duo
. ~/venv-gnu-plct-duo/bin/ruyi-activate
验证GCC版本
riscv64-plct-linux-gnu-gcc -v
获取并编译coremark（GCC）
git clone https://github.com/eembc/coremark
cd coremark
make CC=riscv64-plct-linux-gnu-gcc XCFLAGS="-mcpu=thead-c906 -static" compile
mv coremark.exe coremark-gcc
将GCC构建的二进制传输至开发板
scp ../coremark-gcc root@192.168.42.1:~
返回上级目录并退出ruyi GCC虚拟环境
cd ..; ruyi-deactivate
SSH连接到开发板并执行编译好的二进制
ssh root@192.168.42.1
#如提示Host key verification failed：
#打开当前用户目录下的 .ssh/known_hosts目录，删除192.168.42.1对应行
#登录密码为milkv，提示Are you sure you want to continue connecting时输入yes回车即可
./coremark-gcc
正常情况下，终端会看到类似如下输出：
[rootamilkv-duo]~# ./coremark-gcc

Coremark (LLVM版)
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 -static" compile
mv coremark.exe coremark-llvm
将LLVM构建的二进制传输到开发板
scp ../hello-llvm coremark-llvm root@192.168.42.1:~
返回上级目录并退出ruyi GCC虚拟环境
cd ..; ruyi-deactivate
SSH连接到开发板并执行编译好的二进制
