== '''Introduction to serial debugging tools''' ==
<br>
First you need to prepare a USB to TTL serial cable similar to the picture below:<br>
<div style="padding-left:200px;">[[文件File:Orange-pi-3-img28.png|800px]]</div>Connect the serial cable as shown in the figure below. The From the silk screen on the back of the board, you can see that the corresponding functions of the cables of different colors are as follows:<br>* Black——GNDBlack—GND
* Green-RX
* White-TX
<div style="padding-left:200px;">[[文件File:Orange-pi-3lite2-img29img6.png|800px]]</div>
<br>
=== '''Use on Windows platform''' ===
In the process of using OrangePi for project development, in order to obtain more debugging information, OrangePi supports serial port information debugging by default. For developers, they only need to prepare the materials mentioned above to get serial debugging information. The serial debugging tools used by different host computers are similar. Basically, you can refer to the methods below to deploy. There are many tools for serial debugging on the Windows platform. The commonly used tool is putty. This section uses putty as an example to explain deployment.<br>
<br>
* '''(1)Install USB driver'''<br><br>
Download the latest driver PL2303_Prolific_DriverInstaller_v130.zip, download and unzip.<br>
<div>[[文件File:Orange-pi-3-img30.png|800px]]</div>
Select application installation as administrator<br>
<div style="padding-left:200px;">[[文件File:Orange-pi-3-img31.png|800px]]</div>
Wait for the installation to complete
<div style="padding-left:200px;">[[文件File:Orange-pi-3-img32.png|800px]]</div>* '''Download (2)Download and install Putty'''<br><br>
Putty can be downloaded from the following address, please choose the version suitable for your development environment.<br>
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
<p>Double-click the downloaded putty.exe directly to open putty. The software interface
is shown in the figure below.</p>
* <div style="padding-left:40px;">[[File:Orange-pi-lite2-img7.png|600px]]</div>'''Acquisition (3)Acquisition of equipment information'''<br>
<br>
　In Windows 7, we can check whether the serial port connection is normal and the device number of the serial port through the device manager. If the device is not recognized properly, please check if the driver is successfully installed. If there is a problem with the driver installation, you can try to scan and install the driver using 360 Driver Master.
<div>[[文件File:Orange-pi-3-img33.png|800px]]</div>
<br>
* '''Putty (4)Putty configuration'''<br>
<br>
　Set the serial port to the corresponding port number (COM4), disable flow control, and set the speed to 115200
<div>[[文件File:Orange-pi-3-img34.png|800px]]</div>* Start '''(5)Start debugging serial output'''<br><br>
OrangePi is powered on and putty will automatically print serial port log information<br>
<br>
 
=== '''Use on Linux platform''' ===
<br>
There is not much difference between using putty on the Linux platform and the Windows platform. The following mainly describes the operation steps where there are differences. All operations are based on Ubuntu 14.04 system.<br>
<br>
* '''Install (1)Install and start launch Putty'''<br>
<div style="background:#f1f1f1;border:1px solid #ddd;padding:5px;">
$ sudo apt-get install putty<br>
</div>
<br>
* '''Configure (2)Configure Putty'''<br><br>
