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 wget
 
wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.49.0/ruyi-0.49.0.riscv64
chmod +x ./ruyi-0.49.0.riscv64
sudo cp -v ./ruyi-0.49.0.riscv64 /usr/local/bin/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 --toolchain gnu-plct generic gcc-env
. gcc-env/bin/ruyi-activate

验证GCC版本

riscv64-plct-linux-gnu-gcc -v

编译Hello World（GCC）

cat << EOF > hello.c
#include <stdio.h>
 
int main() {
printf("Hello, World!\n");
return 0;
}
EOF
 
riscv64-linux-gcc -static hello.c -o hello-gcc

PC端传输

python3 -m http.server 8000

在开发板的minicom终端里运行：

wget http://10.13.61.37:8000/hello-gcc -O /root/hello-gcc
chmod +x /root/hello-gcc
/root/hello-gcc

输出结果

[root@canaan ~ ]$ wget http://10.13.61.37:8000/hello-gcc -O /root/hello-gcc

Hello, World!

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 --sysroot-from gnu-plct generic llvm-env
. llvm-env/bin/ruyi-activate

验证LLVM版本

clang-14 -v

编译Hello World（LLVM）

cat > hello_k510.c << "EOF"
#include <stdio.h>
int main() {
    printf("Hello from K510 with Clang!\n");
    return 0;
}
EOF
 
#静态交叉编译
clang-14 -static --target=riscv64-linux-gnu hello_k510.c -o hello_k510

剥离属性段

if [ ! -f "$OBJCOPY" ]; then

$OBJCOPY --remove-section=.riscv.attributes hello_k510 hello_k510_stripped

PC端传输

python3 -m http.server 8000

在开发板的minicom终端里运行：

wget http://10.13.61.37:8000/hello_k510_stripped -O /root/hello_k510_stripped
chmod +x /root/hello_k510_stripped
/root/hello_k510_stripped
