Introduction to the use of the development board

Prepare the necessary accessories

1)TF card, a high-speed card of class 10 or above with a minimum capacity of 8GB, it is recommended to use a SanDisk TF card, the Orange Pi test is to use a SanDisk TF card, other brands of TF cards may cause the system to fail to boot.

2)TF card reader, used to read and write TF card

3)HDMI to HDMI cable, used to connect the development board to an HDMI monitor or TV for display

4)Type-C to HDMI cable, connect the development board to HDMI display or TV through Type-C interface for display

5)Type-C to USB3.0 adapter, used to connect USB3.0 storage devices or USB devices such as mouse and keyboard

6)10.1-inch MIPI screen, used to display the system interface of the development board

7)Power adapter, Orange Pi 4 LTS supports 5V/3A or 5V/4A DC power supply, and also supports 5V/4A Type-C power supply

　It is not recommended to use 5V/3A Type-C power supply, because the system may be unstable due to insufficient power supply. In addition, the Orange Pi 4 LTS cannot be powered through the 5v pin on the 26pin interface

8)USB interface mouse and keyboard, as long as it is a standard USB interface mouse and keyboard, the mouse and keyboard can be used to control the Orange Pi development board
9)Metal heat dissipation shell, Orange Pi 4 LTS matching metal shell is shown in the figure below, because the RK3399/RK3399-T chip generates a relatively large amount of heat, it is necessary to have a metal shell

10)If you don't buy a metal cooling case, it is recommended to add a 5V cooling fan. As shown in the figure below, there are 5V and GND pins on the 26pin interface of the development board that can be connected to the cooling fan. The spacing between the 26pin pin headers is 2.54mm. The power interface of the cooling fan can be purchased from Taobao according to this specification (the development board is plugged into the power supply) After the 5V pin can be used directly, no other settings are required)

11)Fast or Gigabit Ethernet cable to connect the development board to the Internet

12)OV13850 13MP camera, dedicated camera for Orange Pi 4 LTS, compatible with MIPI interface

13)3.3V USB to TTL module and DuPont cable, when using the serial port debugging function, USB to TTL module and DuPont cable are required to connect the development board and computer

14)A PC with Ubuntu and Windows operating systems installed

1	Ubuntu14.04 PC	Optional, used to compile Android source code
2	Ubuntu21.04 PC	Optional, used to compile Linux source code
3	Windows PC	For burning Android and Linux images

Download the image of the development board and related files

1)The download URL of the Chinese version of the file is:

 http://www.orangepi.cn/downloadresourcescn/

2)The download URL of the English version of the file is:

 http://www.orangepi.org/downloadresources/

3)The information mainly includes

a.Android source code: saved on Baidu cloud disk and Google network disk
b.Linux source code: saved on github, the link address is

 https://github.com/orangepi-xunlong/orangepi-build

c.User manual and schematic diagram: The data sheet related to the chip will also be placed here
d.Official tools: mainly include the software that needs to be used during the use of the development board
e.Android image: save on Baidu cloud disk and Google network disk
f.Ubuntu image: save on Baidu cloud disk and Google network disk
g.Debian image: save on Baidu cloud disk and Google network disk

Use the Debian image pre-installed in eMMC to test the function of the development board

　Note that if you purchase the version without eMMC, you cannot pass the Debian image test pre-installed in eMMC, you can only burn the image to the TF card, and then start the system in the TF card to test the function of the development board

　If you purchased the Orange Pi 4 LTS development board with 16GB eMMC, after getting the development board, you can use the Debian 11 image pre-installed in the eMMC to test the functions of the development board, and make sure that all hardware functions of the development board are OK. After that, burn the system you want to use.

Method of burning Linux image to TF card based on Windows PC

　Note that: the Linux image mentioned here refers specifically to the image of a Linux distribution such as Debian or Ubuntu downloaded from the Orange Pi data download page

How to use Win32Diskimager to burn Linux image

1)First prepare a TF card with a capacity of 8GB or more. The transmission speed of the TF card must be above class 10. It is recommended to use a TF card from a brand such as SanDisk

2)Then use the card reader to insert the TF card into the computer

3)Then format the TF card

a.The SD Card Formatter software can be used to format the TF card, and its download address is

 https://www.sdcard.org/downloads/formatter/eula_windows/SDCardFormatterv5_WinEN.zip

b.After downloading, unzip and install directly, and then open the software

c.If only the TF card is inserted into the computer, the “Select card” column will display the drive letter of the TF card. If multiple USB storage devices are inserted into the computer, you can select the drive letter corresponding to the TF card through the drop-down box.

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

e.After formatting the TF card, the information shown in the figure below will pop up, click OK.

4)Download the compressed package of the Linux operating system image file you want to burn from the data download page of Orange Pi, and then use the decompression software to decompress it. In the decompressed file, the file ending with ".img" is the image file of the operating system. The size is generally more than 1GB

5)Use Win32Diskimager to burn the Linux image to the TF card
a.The download page of Win32Diskimager is

 http://sourceforge.net/projects/win32diskimager/files/Archive/

b.After downloading, install it directly. The Win32Diskimager interface is as follows

a) First select the path of the image file
b) Then confirm that the drive letter of the TF card is consistent with the one displayed in the "Device" column
c) Finally click "Write" to start burning

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

b. Then select the drive letter of the TF card
c. Finally, click Flash to start burning the Linux image to the TF card

8)The interface displayed in the process of balenaEtcher burning the Linux image is shown in the figure below. In addition, the progress bar shows purple to indicate that the Linux image is being burned to the TF card.

9)After the Linux image is burned, balenaEtcher will also verify the image burned to the TF card by default to ensure that there is no problem in the burning process. As shown in the figure below, a green progress bar indicates that the image has been burned, and balenaEtcher is verifying the burned image.

10)After the successful burning is completed, the display interface of balenaEtcher is shown in the figure below. If a green indicator icon is displayed, it means that the image burning is successful. At this time, you can exit balenaEtcher, and then pull out the TF card and insert it into the TF card slot of the development board.
