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ruyi包管理器

sudo apt update; sudo apt install -y python3-ruyi

安装GCC和LLVM工具链

ruyi update

ruyi install gnu-plct llvm-plct

Hello World (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

编译并运行Coremark（GCC）

git clone https://github.com/eembc/coremark
cd coremark
make CC=riscv64-plct-linux-gnu-gcc XCFLAGS="-mcpu=xt-c920" compile

./coremark.exe

正常情况下，终端会看到类似如下输出：

$ make CC=riscv64-plct-linux-gnu-gcc XCFLAGS="-mcpu=xt-c920" compile

退出ruyi GCC虚拟环境

cd ..; ruyi-deactivate

Hello World (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_\
