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://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.47.0/ruyi.riscv64
 
chmod +x ruyi.riscv64
 
sudo cp -v ruyi.riscv64 /usr/local/bin/ruyi

安装GCC和LLVM工具链

ruyi update
 
ruyi install gnu-ruyisdk llvm-ruyisdk

Coremark (GCC版)

创建并激活ruyi虚拟环境（GCC）

ruyi venv -t toolchain/gnu-ruyisdk manual venv-gnu-ruyisdk
. venv-gnu-ruyisdk/bin/ruyi-activate

验证GCC版本

riscv64-ruyisdk-linux-gnu-gcc -v

编译并运行Coremark（GCC）

git clone https://github.com/eembc/coremark
cd coremark
make PORT_DIR=posix CC=riscv64-ruyisdk-linux-gnu-gcc XCFLAGS="-march=rv64gc_zba_zbb" compile
 
./coremark.exe

正常情况下，终端会看到类似如下输出：

«Ruyi venv-gnu-ruyisdk» ubuntu@ubuntu:~/coremark$ ./coremark.exe

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-ruyisdk manual --sysroot-from gnu-ruyisdk venv-llvm-ruyisdk
. venv-llvm-ruyisdk/bin/ruyi-activate

验证LLVM版本

clang -v

编译并运行Coremark（LLVM）

cd coremark
make clean
make PORT_DIR=posix CC=clang XCFLAGS="-march=rv64gc_zba_zbb -O3" compile
 
./coremark.exe

正常情况下，终端会看到类似如下输出：

«Ruyi venv-llvm-ruyisdk» ubuntu@ubuntu:~/coremark$ ./coremark.exe
