At this time, you can burn the Android image, please refer to the steps to burn the Android image directly to EMMC through the Type C interface<br>
<br>
=== '''Start the Orange Pi development board''' ===
<br>
1)Insert the TF card with the burned image into the TF card slot of the Orange Pi development board (if you use the image in EMMC, you don't need to insert the TF card)<br>
2)The development board has an HDMI interface, you can connect the development board to a TV or HDMI display through an HDMI to HDMI cable<br>
3)Connect the USB mouse and keyboard to control the Orange Pi development board<br>
4)The development board has an Ethernet port, which can be plugged into a network cable for Internet access<br>
5)Connect a 5V/3A (5V/4A is also available) high-quality power adapter
<div style="padding-left:20px;color:red;">
a. Remember not to plug in the 12V power adapter, if you plug in the 12V power adapter, the development board will be burned out<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 USB to TTL module and DuPont 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>
<br>
=== '''How to use the debug serial port''' ===
<br>
==== '''Debug serial port connection instructions''' ====
<br>
1)First, you need to prepare a USB to TTL module. For better platform compatibility, CH340 USB to TTL module is recommended. Then insert one end of the USB interface of the USB to TTL module into the USB interface of the computer

<br>
2)The corresponding relationship between the debug serial port GND, TX and RX pins of the development board is shown in the figure below
<div>[[文件:Orange-pi-4-img58.png|800px|]]</div>
<br>
3)The GND, TX and RX pins of the USB to TTL module need to be connected to the debug serial port of the development board through a Dupont cable
<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 RX of the USB to TTL module to the TX of the development board<br>
c. Connect the TX of the USB to TTL module to the RX of the development board
</div>
<br>
4)The schematic diagram of connecting the USB to TTL module to the computer and the Orange Pi development board is shown below

<br>
5)If you are using a CP2102 USB to TTL module, under the condition of a baud rate of 1.500000, some systems may encounter garbled or unusable problems. The specific test situation is as follows
