=== '''Use the Android image pre-installed in eMMC to test the functions of the development board''' ===
<br>
Orange Pi PC Plus has 8GB of eMMC onboard. Before leaving the factory, the factory will pre-install Android image to eMMC for testing. After getting the development board, you can use the pre-installed Android image in eMMC to test the functions of the development board and confirm the development. After all the functions of the board are ok, then burn the system you want to use<br>
<br>
=== '''Method of flashing Linux image to TF card based on Windows PC''' ===
<br>
1)First, prepare a TF card with 8GB or larger capacity. The transmission speed of the TF card must be above class10. It is recommended to use a TF card of SanDisk and other brands<br>
<br>
2)Then use the card reader to insert the TF card into the windows computer<br>
<br>
3)Then format the TF card<br>
<div style="padding-left:20px;">

4)The development board has an Ethernet port, which can be plugged into a network cable for Internet access<br>
5)Connect a power adapter with 5V and at least 2A (3A is also possible)<br>
<div style="padding-left:20px;>
a.Remember not to plug in the 12V power adapter, if the 12V power adapter is plugged in, it will burn out the development board<br>
b.Many unstable phenomena during system power-on and startup are basically caused by power supply problems, so a reliable power adapter is very important
</div>
6)Then turn on the switch of the power adapter, if everything is normal, the HDMI display will be able to see the startup screen of the system at this time<br>
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<br>
=== '''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
<div style="padding-left:200px">[[文件:Orange-pi-one-img9.png|600px]]</div>
2)The corresponding relationship between the debug serial port GND, TXD and RXD pins of the development board is shown in the figure below
<div style="padding-left:200px">[[文件:Orange-pi-pc-plus-img7.png|600px]]</div>
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<br>
<div style="padding-left:20px">
a. Connect the GND of the USB to TTL module to the GND of the development board<br>
b. Connect the RXD of the USB to TTL module to the TXD of the development board<br>
c. Connect the TXD of the USB to TTL module to the RXD of the development board

<br>
3)First install putty on the Ubuntu PC
<div style="background:#f1f1f1;border:1px solid #000">
test@test:~$ '''sudo apt update'''<br>
test@test:~$ '''sudo apt -y install putty'''
</div>
<br>
4)Then run putty, remember to add sudo permissions
<div style="background:#f1f1f1;border:1px solid #000">
test@test:~$ '''sudo putty'''
</div>
<br>
5)After executing the putty command, the following interface will pop up

<br>
6)First select the setting interface of the serial port
<div style="padding-left:200px">[[文件:Orange-pi-3lts-putty1.png|600px]]</div>
7)Then set the parameters of the serial port<br>
<div style="padding-left:20px;">
a. Set the Serial line to connect to to /dev/ttyUSB0 (modify to the corresponding node name, generally /dev/ttyUSB0)<br>
b. Set Speed (baud) to 115200 (baud rate of the serial port)<br>
c. Set Flow control to None
</div>
<div style="padding-left:200px">[[文件:Orange-pi-3lts-putty2.png|600px]]</div>
8)After setting the serial port setting interface, return to the Session interface
<div style="padding-left:20px;">

<div style="padding-left:20px;>
a.Remember not to plug in the 12V power adapter, if the 12V power adapter is plugged in, it will burn out the development board<br>
b.Many unstable phenomena during system power-on and startup are basically caused by power supply problems, so a reliable power adapter is very important
</div>
6)Then turn on the switch of the power adapter, if everything is normal, the HDMI display will be able to see the startup screen of the system at this time<br>
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<br>
=== '''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
<div style="padding-left:200px">[[文件:Orange-pi-one-img9.png|600px]]</div>
2)The corresponding relationship between the debug serial port GND, TXD and RXD pins of the development board is shown in the figure below
<div style="padding-left:200px">[[文件:Orange-pi-pc-plus-img7.png|600px]]</div>
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<br>
<div style="padding-left:20px">
a. Connect the GND of the USB to TTL module to the GND of the development board<br>
b. Connect the RXD of the USB to TTL module to the TXD of the development board<br>

<br>
6)First select the setting interface of the serial port
<div style="padding-left:200px">[[文件:Orange-pi-3lts-putty1.png|600px]]</div>
7)Then set the parameters of the serial port<br>
<div style="padding-left:20px;">
a. Set the Serial line to connect to to /dev/ttyUSB0 (modify to the corresponding node name, generally /dev/ttyUSB0)<br>
b. Set Speed (baud) to 115200 (baud rate of the serial port)<br>
c. Set Flow control to None
</div>
<div style="padding-left:200px">[[文件:Orange-pi-3lts-putty2.png|600px]]</div>
8)After setting the serial port setting interface, return to the Session interface
