<br>

2)The download URL of the English version is:<br>

<br>

3)The information mainly contains<br>

<br>

c.If the computer only has a TF card inserted, the TF card's drive letter will be displayed in the Select card column. If the computer has multiple USB storage devices inserted, you can select the drive letter corresponding to the TF card through the drop-down box<br>

d.Then click Format, a warning box will pop up before formatting, and formatting will start after selecting "Yes (Y)"

e.After formatting the TF card, the message shown in the figure below will pop up, click OK<br>

</div>

5)Download the Linux operating system image file compression package you want to burn from the Orange Pi data download page, and then use the decompression software to decompress it. In the decompressed file, the file ending with ".img" is the operating system image file,the size is generally above 1GB.<br>

c)Finally click '''"Write"''' to start burning

</p>

c.After the image writing is completed, click the "Exit" button to exit, and then you can pull out the TF card and insert it into the development board to start

</div>

5)After entering the balenaEtcher download page, please select the Linux version of the software through the drop-down box to download<br>

<br>

<br>

6)After downloading, use unzip to decompress. The decompressed balenaEtcher-1.5.109-x64.AppImage is the software needed to burn Linux image

c. Finally click Flash to start burning

</div>

10)The writing speed and remaining time will be prompted during the burning process

11)After burning, the following interface will be displayed. At this time, you can unplug the TF card from the computer and insert it into the development board to start.

=== '''Method of flashing Android firmware to TF card''' ===

<br>

5) Use decompression software to decompress SDDiskTool_v1.59, this software does not need to be installed, find SD_Firmware_Tool in the decompressed folder and open it

<br>

6)After opening SD_Firmware_Tool, if the TF card is recognized normally, the name and capacity of the TF card will be displayed when the removable disk device is selected. <span style="color:red;">Please make sure that the displayed TF card device information is consistent with the device information of the TF card you want to burn.</span> There is no display, you can try to unplug the TF card<br>

7)After confirming the device information, start writing the Android firmware to the TF card<br>

<div style="padding-left:20px;">

b. Select the path of Android image in "Select Firmware Upgrade"<br>

c. Then click the "Start Create" button<br>

<br>

d.After clicking "Start to create", a warning box will pop up, select "Yes (Y)" to start burning

<br>

e.After starting to burn, the partition currently being burned will be displayed below

<br>

</div>

8)After burning, the display of SD_Firmware_Tool is as shown in the figure below. At this time, click the OK button to close SD_Firmware_Tool, and then you can unplug the TF card from the computer and insert it into the development board to start<br>

==== '''Debug serial port connection instructions''' ====

1)First, you need to prepare a USB to TTL module. This module can be bought in Orange Pi Store. If there are other similar USB to TTL modules, you can also insert the USB port of the USB to TTL module into the USB of the computer Interface

2)The corresponding relationship between the debug serial port GND, TX and RX pins of the development board is shown in the figure below

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<br>

<div style="padding-left:20px">

<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

<br>

5)After executing the putty command, the following interface will pop up

<br>

6)First select the setting interface of the serial port

7)Then set the parameters of the serial port<br>

<div style="padding-left:20px;">
