Get hiburn tool

Through the official documents of Hongmeng, we know that deveco device tool is a vscode plug-in, which is provided to developers in the form of. Vsix files. In fact, this. Vsix file is a zip file. You can use the file command to identify it in Git bash or Linux Environment:

$ file DevEcoDeviceTool-1.0.0.vsix
DevEcoDeviceTool-1.0.0.vsix: Zip archive data, at least v2.0 to extract

On windows, you can use general compression and decompression software to open it and unzip it.

After decompression, you can see a file named hiburn.exe in the subdirectory of extension \ deveco \ tools, which is the hiburn tool we will introduce today (you can also download hiburn.zip directly from the attachment of this article).

Comparison with deveco device tool

Compared with burning with deveco device tool, hiburn has the following advantages:

  1. Without relying on vscode, you don’t need to install vscode, nodejs, JDK and some NPM packages;
  2. The download speed is faster. The maximum baud rate of hiburn.exe can be set to 3000000, while the maximum baud rate of deveco device tool can only be 921600, which is three times that of it;

The main disadvantages of hiburn burning are:

  1. You need to manually click disconnect to actively disconnect, otherwise the download will be repeated by default; After the burning is successful, if you keep opening the serial port and press the reset button again, you will find that it burns again.
  2. The serial port parameters of hiburn cannot be saved. After you close it, you need to reset it next time you open it, while deveco can save the serial port parameters;
  1. Hiburn has more and more complicated operation steps than deveco;
