# Burning


Hi3861 V100 supports burning through the serial port. To burn source code through the serial port in Windows, perform the following steps:


1. Connect the computer and the target development board through the serial port and USB port. For details, see [Introduction to the Hi3861 V100 Development Board](https://gitee.com/openharmony/docs/blob/master/en/device-dev/quick-start/quickstart-lite-introduction-hi3861.md).

2. In DevEco Device Tool, choose **REMOTE DEVELOPMENT** > **Local PC** to check the connection status between the remote computer (Ubuntu build environment) and the local computer (Windows build environment).

   - If ![en-us_image_0000001261315939](figures/en-us_image_0000001261315939.png) is displayed on the right of **Local PC**, the remote computer is connected to the local computer. In this case, no further action is required.
   - If ![en-us_image_0000001261515989](figures/en-us_image_0000001261515989.png) is displayed, click the connect icon.

   > This operation is required only in remote access mode (in the Windows+Ubuntu hybrid build environment). If the local access mode (Windows or Ubuntu build environment) is used, skip this step.

3. Check the serial port number in **QUICK ACCESS** > **DevEco Home** > **Device** in DevEco Device Tool.
