Burning an Image

The following exemplifies how to burn an image to Hi3861 using Hi3861. You can also do so using DevEco Device Tool, by following instructions in Burning an Image.

Prerequisites

• The source code of the development board has been compiled into files for burning.

• HiBurn has been installed on the client platform (for example, a Windows-based computer).

• The USB-serial adapter driver has been installed on the client platform. For details, see Installing the USB-Serial Adapter Driver.

• A serial port terminal tool, such as IPOP, has been installed on the client platform.

• The client platform is connected to the development board through a USB cable.

Procedure

1. Prepare the files to be burnt.

   1. On the client platform, create a folder for storing the files to be burnt, for example, D:\hi3861.
   2. Download the compiled source package to the client platform, decompress the package, and copy the files required for burning to the folder created in step 1. Specifically, the files required for burning are Hi3861_wifiiot_app_allinone.bin and Hi3861_loader_signed.bin.

2. Burn the files using HiBurn.
