Follow these steps to set up the R1 device firmware with the example project.

## Download and configure the device firmware [#download-and-configure-the-device-firmware]

1. Clone the `bk_aidk` project from GitHub:

   ```bash
   git clone --recurse-submodules https://github.com/bekencorp/bk_aidk.git -b ai_release/v2.0.1
   cd bk_aidk
   git checkout ai_release/v2.0.1.8
   git submodule update --recursive
   ```

2. Replace the `projects` directory with the example demo directory. Replace `<bk_aidk_path>` with your actual path:

   ```bash
   rm -rf <bk_aidk_path>/projects/
   cp -r ./projects <bk_aidk_path>/projects
   ```

   <CalloutContainer type="info">
     <CalloutTitle>
       Info
     </CalloutTitle>

     <CalloutDescription>
       To avoid conflicts, delete the original `projects` directory before copying.
     </CalloutDescription>
   </CalloutContainer>

3. Update the server URL in `projects/common_components/network_transfer/agora_rtc/agora_config.h` to point to your deployed server:

   ```cpp
   #define CONFIG_AGENT_SERVER_URL "http://192.168.1.100:5001"
   ```

   Replace `http://192.168.1.100:5001` with your server address.

## Build the firmware [#build-the-firmware]

Build the sample project firmware from the `bk_aidk` directory:

```bash
cd <bk_aidk_path>
make bk7258 PROJECT=beken_genie
```

Replace `<bk_aidk_path>` with your actual `bk_aidk` directory path.

## Flash the firmware [#flash-the-firmware]

After the firmware builds successfully, flash it to your R1 device. For detailed instructions, see the [BK official documentation](https://docs.bekencorp.com/arminodoc/bk_idk/bk7258/en/v2.0.1/get-started/index.html).
