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版)

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

获取并编译coremark（GCC）

git clone https://github.com/eembc/coremark
cd coremark
make CC=riscv64-plct-linux-gnu-gcc XCFLAGS="-mcpu=xt-c910" compile
./coremark.exe

正常情况下，终端会看到类似如下输出：

$ make CC=riscv64-linux-gnu-gcc XCFLAGS="-mcpu=xt-c910" compile
riscv64-linux-gnu-gcc -O2 -Ilinux -Iposix -I. -DFLAGS=\"-O2 -mcpu=xt-c910 -lrt\" -DITERATIONS=0 -mcpu=xt-c910 core_list_join.c core_main.c core_matrix.c core_state.c core_util.c posix/core_portme.c -o ./coremark.exe -lrt

返回上级目录并退出ruyi GCC虚拟环境

cd ..; ruyi-deactivate

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

编译并运行coremark（LLVM）

cd coremark; make clean; make CC=clang XCFLAGS="-march=rv64imafdc_zicntr_zicsr_zifencei_zihpm_zfh_\
xtheadba_xtheadbb_xtheadbs_xtheadcmo_\
xtheadcondmov_xtheadfmemidx_xtheadmac_xtheadmemidx_xtheadmempair_xtheadsync" compile

./coremark.exe

正常情况下，终端会看到类似如下输出：
