Burning

Burning is the process of downloading compiled program files to a development board to provide a basis for subsequent debugging. With the one-click burning function of DevEco Device Tool, you can burn images on development boards quickly and efficiently.

Hi3516D V300 supports burning through the USB port, network port, and serial port. This document describes how to burn source code through the USB port. The operations are performed in Windows.

Connect the computer and the target development board through the serial port and USB port. For details, see Introduction to the Hi3516D V300 Development Board. > NOTE > If you are using the remote access mode (Windows + Ubuntu on the local VM), disable the USB control of the VM as follows to ensure that the development board is connected to the USB port of the host: > > - VMware: Configure the device to connect to the host under Preferences > USB and remove the USB controller from the VM settings. > > - VirtualBox: Deselect Enable USB Controller in the USB device options under Ubuntu settings.
If your computer does not have the USB port driver or USB-to-serial driver, install it by following the instructions in Installing the USB Port Driver on the Hi3516D V300 or Hi3518E V300 Development Board or Installing the Serial Port Driver on the Hi3516D V300 or Hi3518E V300 Development Board, depending on the missing driver.
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 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.
