RuyiSDK Getting Started Example

Install dependencies

sudo apt update; sudo apt install -y wget tar zstd xz-utils git build-essential

Install the ruyi package manager (see the official installation guide for other methods)

wget https://mirror.iscas.ac.cn/ruyisdk/ruyi/tags/0.51.0/ruyi-0.51.0.amd64
chmod +x ./ruyi-0.51.0.amd64
sudo cp -v ./ruyi-0.51.0.amd64 /usr/local/bin/ruyi

Install the GCC and LLVM toolchains

ruyi update

ruyi install gnu-plct llvm-plct

Hello World (GCC)

Create and activate the ruyi virtual environment (GCC)

ruyi venv -t toolchain/gnu-plct generic venv-gnu-plct-duo

. ~/venv-gnu-plct-duo/bin/ruyi-activate

Verify the GCC version

riscv64-plct-linux-gnu-gcc -v

Compile Hello World (GCC)

cat > hello.c << 'EOF'
#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}
EOF

riscv64-plct-linux-gnu-gcc hello.c -o hello-gcc

Transfer the GCC-built binary to the development board

scp ../hello-gcc root@192.168.42.1:~

Return to the parent directory and exit the ruyi GCC virtual environment

cd ..; ruyi-deactivate

Connect to the development board over SSH and run the compiled binary

ssh root@192.168.42.1

# If you see Host key verification failed：

# Open the .ssh/known_hosts file in the current user's home directory and delete the line corresponding to 192.168.42.1

# The login password is milkv; when prompted with Are you sure you want to continue connecting, enter yes and press Enter

./hello-gcc

Under normal circumstances, the terminal displays output similar to:

[root@milkv-duo]~# ./hello-gcc
Hello, World!
[root@milkv-duo]~#

Hello World (LLVM)

Create and activate the ruyi virtual environment (LLVM)

ruyi venv -t toolchain/llvm-plct manual --sysroot-from gnu-plct venv-llvm-plct

. ~/venv-llvm-plct/bin/ruyi-activate

Verify the LLVM version

clang -v

Compile Hello World (LLVM)

clang hello.c -o hello-llvm;

Transfer the LLVM-built binary to the development board

scp ../hello-llvm root@192.168.42.1:~

Return to the parent directory and exit the ruyi LLVM virtual environment

cd ..; ruyi-deactivate

Connect to the development board over SSH and run the compiled binary

ssh root@192.168.42.1

# If you see Host key verification failed：

# Open the .ssh/known_hosts file in the current user's home directory and delete the line corresponding to 192.168.42.1

# The login password is milkv; when prompted with Are you sure you want to continue connecting, enter yes and press Enter

./hello-llvm

Under normal circumstances, the terminal displays output similar to:

[root@milkv-duo]~# ./hello-llvm
Hello, World!
[root@milkv-duo]~#
