<p style="text-indent:20px;color:#ff0000;font-weight:700">Android image can only be burned to EMMC using PhoenixCard software under Windows platform, but cannot be burned under Linux platform</p>
<br>
1)First of all, please note that burning the Android firmware to the eMMC of the development board needs to be completed with the help of a TF card, which is mainly divided into the following two steps<br>
　a. First use PhoenixCard to burn the Android firmware to the TF card as '''a mass production card'''<br>
　b. Then use TF card to burn Android firmware into eMMC<br>
<br>
2)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>
3)Then use a card reader to insert the TF card into the computer<br>
<br>
4)Download Android 9.0 firmware and PhoenixCard burning tool from http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/service-and-support/Orange-pi-3-LTS.html, please make sure that the version of PhonenixCard tool is '''PhoenixCard v4.1.2 or PhoenixCard v4.1.2 or higher'''<br>

<div style=" ">[[File:Orange-pi-3lts-phoenixcard.png|600px]]</div>
<br>
7)After opening '''PhoenixCard''', if the TF card is recognized normally, the drive letter and capacity of the TF card will be displayed in the middle list. <span style="color:#ff0000;font-weight:700;">Please make sure that the displayed drive letter is consistent with the drive letter of the TF card you want to burn.</span> There is no display, you can try to unplug and insert the TF card
<div style="  ">[[File:Orange-pi-3lts-addimg1.png|600px]]</div>
<br>
8)After confirming the drive letter, format the TF card first, click the restore card button in PhoenixCard, or use the aforementioned '''SD Card Formatter''' to format the TF card
<div style=" ">[[File:Orange-pi-3lts-phoenixcard6.png|600px]]</div>
<br>
9)Then start to write the Android firmware to the TF card<br>
　a. First select the path of Android firmware in the '''"Firmware"''' column<br>
　b. Select '''"mass production card"''' in the '''type of "production"''' card<br>
　c. Then click the '''"Burn Card"''' button to start burning
<div style=" ">[[File:Orange-pi-3lts-phoenixcard7.png|600px]]</div>
<br>
10)After burning, PhoenixCard will display as shown in the figure below. At this time, click the close button to exit PhoenixCard
<div style=" ">[[File:Orange-pi-3lts-phoenixcard8.png|600px]]</div>
<br>
11)Then insert the TF card into the development board. After powering on the development board, the Android firmware in the TF card will be automatically burned into the eMMC of the development board. During the burning process, the red light on the development board will keep flashing. If the development board is connected to an HDMI display, the progress bar of burning Android firmware to eMMC will be displayed on the HDMI display
<div style=" ">[[File:Orange-pi-3lts-progressbar.png|600px]]</div>
<br>
12)After the burning is completed, the HDMI display is shown in the figure below, and then the development board will automatically shut down
<div style=" ">[[File:Orange-pi-3lts-progressbarsuccess.png|600px]]</div>
<br>
13)At this time, you can pull out the TF card, then power on again, and the Android system in eMMC will start<br>
<br>

=== ''' Start the Orange Pi development board''' ===

1)The development board has an on-board eMMC, which has an Android9.0 image burned by default, and you can directly use the image in the eMMC to start and fully test the function when you just get the development board.<br>

2)If you need to use linux image, you can insert the TF card with the burned linux image into the TF card slot of the Orange Pi development board<br>


3)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>


4)Connect the USB mouse and keyboard to control the Orange Pi development board<br>


5)The development board has an Ethernet port, which can be plugged into the network cable for Internet access<br>


6)Connect a 5V/3A high-quality power adapter<br>

<p style="padding-left:30px;color:#ff0000;font-weight:700;">a. Remember not to plug in the 12V power adapter, if you plug in the 12V power adapter, it will burn out the development board<br>
b. Many unstable phenomena during the power-on and startup of the system are basically caused by power supply problems, so a reliable power adapter is very important</p><br>

7)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>


8)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

=== ''' How to use the debug serial port''' ===
