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>

　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.

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>

<div style="background:#f1f1f1;border:1px solid #ddd;padding:5px;">

$ sudo apt-get install putty<br>

</div>

<br>

The serial number can be viewed through ls / dev / ttyUSB *<br>

Baud rate needs to be set to 115200<br>
