7)If you want to view the output information of the system through the debug serial port, please use the serial cable to connect the development board to the computer. For the connection method of the serial port, please refer to the section on the use of the debug serial port
How to use the debug serial port
Debug serial port connection instructions
1)First, you need to prepare a USB to TTL module. This module can be bought in Orange Pi stores. If there are other similar USB to TTL modules, you can also insert the USB end of the USB to TTL module into the USB port of the computer
2)The corresponding relationship between the debug serial port GND, TXD and RXD pins of the development board is shown in the figure below
3)The GND, TXD and RXD pins of the USB to TTL module need to be connected to the debug serial port of the development board through a DuPont cable
a. Connect the GND of the USB to TTL module to the GND of the development board
b. Connect the RXD of the USB to TTL module to the TXD of the development board
c. Connect the TXD of the USB to TTL module to the RXD of the development board
4)The schematic diagram of connecting the USB to TTL module to the computer and the Orange Pi development board is shown below
How to use the debugging serial port on Ubuntu platform
1)If the USB to TTL module is connected normally, you can see the corresponding device node name under /dev of the Ubuntu PC, remember this node name, it will be used when setting the serial port software later
test@test:~$ ls /dev/ttyUSB*
/dev/ttyUSB0
2)There are many serial debugging tools that can be used under linux, such as putty, minicom, etc. The following demonstrates how to use putty
3)First install putty on the Ubuntu PC
test@test:~$ sudo apt update
test@test:~$ sudo apt -y install putty
4)Then run putty, remember to add sudo permissions
test@test:~$ sudo putty
5)After executing the putty command, the following interface will pop up
6)First select the setting interface of the serial port
7)Then set the parameters of the serial port
a. Set the Serial line to connect to to /dev/ttyUSB0 (modify to the corresponding node name, generally /dev/ttyUSB0)
b. Set Speed (baud) to 115200 (baud rate of the serial port)
c. Set Flow control to None
8)After setting the serial port setting interface, return to the Session interface
a. First select the Connection type as Serial
9)After starting the development board, you can see the Log information output by the system from the opened serial port terminal
How to use the debugging serial port on Windows platform
