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 milkv-duo venv-gnu-plct-duo

. ~/venv-gnu-plct/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-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：

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 ../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

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
