Please refer to the links below to find more information and SOPs that developers often need to use.
Include OS build, check SN(PPID), debug, console, change boot logo, GPIO, etc.
And also detail information of Tinker Board 2, Tinker Board 3N, Tinker Board R2.0, Tinker Board, Tinker Edge R, Tinker V series.
-
For 4-pin power in header (Tinker Edge R)?
you can take reference with this MOLEX/50579404
-
PPID is not from CPU ID.
PPID is ASUS's device ID on the production control line, which can also be used for customer service as S/N, and is a unique value.
-
Because of Tinker Board or Tinker Board R2.0 series is based on RK3288.
And Tinker Board 2 series is RK3399, their GPIO pin define and cpu pin is different with Tinker Board.
Thanks.

Hi,
Usually, before you use `cv2.open`, should have a define codes to let cv2 know use which camera.
so should such as:
import cv2 cam0 = cv2.VideoCapture(0) cam1 = cv2.VideoCapture(1) ret0, frame0 = cam0.read()
and node ID is based on your camera node in system.

User Guides for Linux
Linux
- Linux is a general-purpose operating system with powerful network function. As its hardware consumption such as memory is also less, it is mostly used in network servers.
- Extremely stable, safe, freely redistributable and modifiable
- Linux features advantages such as open source, no copyright as many users in the technical community. Open source allows users to tailor freely, which help Linux system with high flexibility, powerful functions and low cost.
- Disadvantages: It is more difficult to get started than Windows. Due to the lack of desktop Linux ecosystem, there are very few users who use it.
Why Learn Linux
-
Linux systems are widely used in people's daily life, such as mobile phones, smart homes, automotive electronics, wearable devices, etc., but many people do not know that these electronic products are running Linux systems, for example, the Android system we use is developed based on the Linux kernel.
- More than 90% of the world's 1 million top fields use Linux systems; most of the world's stock exchanges are deployed based on Linux systems, including the New York Stock Exchange, Nasdaq, etc.
- World-renowned e-commerce platforms such as Taobao, Amazon, eBay, and Walmart are all using Linux systems.
- The developers and companies involved in the development of the Linux kernel are also the largest and most active. So understanding and learning Linux is very important.
Terminal
-
The terminal on the computer allows users to control their system. Windows users may already be exposed to Command Promptor Powershell, and mac OS users may already be familiar with Terminal. All these tools allow users to directly operate their systems by using commands.
- linaro: current username/login
- linaro-alip: default hostname
- ~: The directory where the current user is located is /home/linaro
- $: indicates that the current logged in user is a normal user
- #: indicates that the root user is logged in
- Type the command in a terminal window and press Enter on your keyboard to run the command.
Linux system directory
- In Windows, each partition is a tree structure, and there are as many partitions as there are tree structures. However, in Linux, there is only one tree structure, and all files and partitions exist in a tree structure. In this structure, the top layer is the root directory, and all other directories, files, and partitions are established under the root directory. Readers can view the documents of the entire root directory through the ls / command, as shown in the figure.
Here is an explanation of these directories:Common directory
-
/home: User directory.
- Except for the root user, all other user data are stored in this directory. In the Tinker Board 2 system, there is a linaro subdirectory in the /home directory, which is the default directory of the linaro user.
-
/bin: Mainly place the necessary executable file directory of the system.
- Place binary executables related to the Linux system (including those required to run the graphical interface), such as ls, mkdir, rm, etc.
-
/boot: Boot directory.
- It is used to store the system boot program, such as the linux kernel and the startup configuration file. The config.txt in it is also the most frequently used file for user configuration.
-
/etc: directory for storing system configuration files
- In this directory, almost all configuration files required by Linux system software are stored. If you need to modify the text in this directory, it is best to back up the files that need to be modified to ensure that you can return to the file after modification. to the original state.
Other directories
- /dev : Device directory. In Linux system, all devices are regarded as files, and all devices are stored in this directory. For example, the first SATA hard disk or U disk will be recognized as sda file, and the first partition of SATA hard disk or U disk will be recognized as sda file. Recognized as sda1 file.
- /lib: The dynamic link library storage location of the basic system. In this directory, the library files required to maintain a basic system startup are stored. Without this directory, system programs simply cannot work.
The directory of the /lost + found/ partition system. The files generated by the abnormal shutdown of the system are usually stored here, and the files generated after the hard disk is repaired by programs such as fsck are also stored here.
- /media: The linux system will automatically identify some devices, such as U disk, CD-ROM, etc. After identification, Linux will mount the identified device to this directory.
- /mnt: Traditional external device mount point. In the early days, other partitions except the system partition, such as U disk and other devices, would be mounted to this directory for users to read and write. However, it has now been replaced by /media/.
- /proc: proc is a virtual filesystem. This directory is stored in memory, so it does not take up hard disk space, and the system or the user learns about them by reading these devices. For example, you can use the cat /proc/cpuinfo command to view CPU information.
- /root: This directory is the home directory of the system administrator, also known as the super-authorized user.
- /srv: This directory stores data that needs to be extracted after some services are started.
- /sys: Like the /proc directory, it is also a virtual directory, which is implemented by the sysfs system in the kernel. Its function is somewhat similar to that of proc, but in addition to the same function of viewing and setting kernel parameters as proc, it also has the same function as proc. There is a unified device model for Linux for management purposes.
- /tmp: Temporary directory. Temporary files generated by the program will be stored in this directory. Don't worry about this directory taking up too much space, because the contents of this directory will be cleared every time the system is started; at the same time, this is one of the few systems that has all user-readable files. Directory to write properties to.
- /usr: The programs installed in the Linux system are stored in this directory, similar to the program files directory under Windows.
- /run: The file used to store the system information when the system is started. This directory was originally under the /var/ directory, but is now elevated to the root directory
Important directory
- In the Linux system, there are several directories that are more important. Usually, you need to be careful not to delete or arbitrarily change the internal files.
- /etc: This is the configuration file in the system. If you change a file in this directory, the system may not start.
- /bin, /sbin, /usr/bin, /usr/sbin: This is the default directory where the executable files are placed by the system. For example, ls is in the /bin/ls directory.
- /bin, /usr/bin are instructions for system users (normal users except root), and /sbin, /usr/sbin are instructions for root.
- /var: This is a very important directory. There are many programs running on the system, so each program will generate corresponding logs, and these logs will be recorded in this directory, specifically in the /var/log directory.
Introduction to common commands
Document system
sudo
- sudo command executes commands as system administrator
- To use the root user, log in as the linaro user and execute the following command
sudo su #switch to superuser su linaro #switch to normal user
ls
The ls command is used to display the contents of the specified working directory (list the files and subdirectories contained in the current working directory).
Common commandsls ls -a #Show all files and directories (starting with . hidden files are also listed) ls -l #In addition to the file name, it also lists the file type, permissions, owner, file size and other information in detail ls -lh #File sizes are listed in an easy-to-understand format, such as 4K
- To learn about more parameters of the command, we can use the help command to view
ls --help
chmod- The chmod command is a command that controls users's permissions on files.
- The file calling permissions of Linux/Unix are divided into three levels: file owner (Owner), user group (Group), other users (Other Users)
- In the figure below, the detailed file information under the Linux root directory is displayed. Among these file information, the most important is the first column, which describes the permissions of files and directories in detail, while the third and fourth columns show which user or group the file and directory belong to.
- There are three file attributes in Linux: read-only (r), write (w), and executable (x). However, the above file attributes are divided into 10 small cells, because in addition to the first cell displaying the directory, the other three groups of three cells respectively represent the file owner permissions, permissions within the same group and other user permissions.
-
- If d is displayed in the first column, it means that this is a directory; if it is a link file, l is displayed here; if it is a device file, c is displayed.
- The first rwx field: -rwx------ indicates the permissions owned by the file owner.
- The second rwx field: ---rwx--- indicates user rights within the same workgroup.
- The third rwx field: ------rwx indicates other user rights.
- E.g:
- -rwx rwx rwx means that no matter which user can read, write and execute this file.
- -rw- --- --- Indicates that only the file owner has read and write permissions, but no execute permissions.
- -rw -rw -rw means that all users have read and write rights.
-
Symbolic Pattern
- who(user type)
who user type description u group file owner group o others all other users a all All users, equivalent to ugo -
- operator(Symbolic pattern)
Operator description + Add permissions for the specified user type - Remove permissions for a specified user type = Set the specified permissions for users, that is, reset all permissions for the user -
- symbol pattern table for permission
Mode Name Description r read set to read w write set to write x execute set to executable X special execution permission Only when the file is a directory file, or other types of users have executable permissions, set the file permissions to executable s setuid/gid When the file is executed, set the file's setuid or setgid permissions according to the user type specified by the who parameter t paste bit set paste bit, only superuser can set this bit, only file owner u can use this bit -
- Symbolic Pattern Examples
1. Add read permissions to all users of the file
chmod a+r file
2. Remove execute permission for all users of file
chmod a-x file
3. Add read and write permissions to all users of file
chmod a+rw file
4. Add read, write and execute permissions to all users of file
chmod +rwx file
5. Set read and write permissions to the owner of the file, clear all permissions of the user group and other users to the file (space means no permission)
chmod u=rw,go= file
6. Add read permission to the user for all files in the directory waveshare and its subdirectory hierarchy, and remove read permission for the user group and other users
chmod -R u+r,go-r waveshare
-
Octal syntax
- The chmod command can use octal numbers to specify permissions. The permission bits of a file or directory are controlled by 9 permission bits, each of which is a group of three, which are read, write, and execute for the file owner (User), read, write, and execute for the user group (Group). Other users (Other) read, write, execute.
# Permission rwx binary system 7 read+write+excute rwx 111 6 read+write rwx- 110 5 read+execute rwx 101 4 read r-- 100 3 read+execute -wx 011 2 write -w- 010 1 execute --x 001 0 none --- 000 -
- 765 is explained as follows:
- The owner's permission is expressed in numbers: the sum of the numbers of the owner's three permission bits. For example, rwx, which is 4+2+1, should be 7.
- The permissions of a user group are expressed in numbers: the sum of the numbers of the permission bits that belong to the group. For example, rw-, which is 4+2+0, should be 6.
-
ermission digital expression of other users: the sum of the numbers of other users' permission bits. For example, r-x, which is 4+0+1, should be 5.
- Common digital rights
- 400 -r------- The owner can read, no one else can do anything;
- 644 -rw-r–r-- all owners can read, but only the owner can edit;
- 660 -rw-rw---- Both owner and group users can read and write, others cannot perform any operations;
- 664 -rw-rw-r-- readable by everyone, but editable only by owner and group users;
- 700 -rwx------ The owner can read, write and execute, other users cannot do anything;
- 744 -rwxr–r-- everyone can read, but only the owner can edit and execute;
- 755 -rwxr-xr-x everyone can read and execute, but only the owner can edit;
- 777 -rwxrwxrwx everyone can read, write and execute (this setting is not recommended)
-
Example
- Add permissions for reading to all users of the file, and the owner and group users can edit
sudo chmod 664 file
Touch
The touch command is used to modify the time of a file or directory, including accessing time and changing time. If the file does not exist, the system will create a new file. For example, in the current directory, use this command to create a blank file "file.txt" and enter the following command:touch file.txt
mkdir
- The command of mkdir is used to create directories.
- In the working directory, create a subdirectory named waveshare:
sudo mkdir waveshare
- Create a directory named waveshare/test in the working directory.
sudo mkdir -p waveshare/test
- If the waveshare directory does not already exist, create one. (Note: If the -p parameter is not added in this example, and the original waveshare directory does not exist, an error will occur.)
cd
- Switch to current working directory
cd .. #Return to the previous directory cd /home/linaro #Enter the /home/linaro directory cd #Return to user directory
cp
- The cp command is mainly used to copy files or directories.
-
parameter:
- -a: This option is usually used when copying directories, it preserves links, file attributes, and copies everything under the directory. Its effect is equal to the combination of dpR parameters.
- -d: keep links when copying. The links mentioned here are equivalent to shortcuts in Windows systems.
- -f: Overwrite existing object files without prompting.
- -i: Contrary to -f, give a prompt before overwriting the target file, asking the user to confirm whether to overwrite, and answering y the target file will be overwritten.
- -p: In addition to copying the contents of the file, also copy the modification time and access rights to the new file.
- -r: If the given source file is a directory file, all subdirectories and files in the directory will be copied.
- -l: Do not copy files, just generate link files.
- Use the cp command to copy all the files in the current directory test/ to the new directory newtest, and enter the following command
sudo cp –r test/ newtest
mv
- The mv command is used to rename a file or directory, or move a file or directory to another location.
parameter:
-
- -b: When the target file or directory exists, create a backup of it before performing the overwrite.
- -i: If the specified source directory or file to be moved has the same name as the target directory or file, it will first ask whether to overwrite the old file. Enter y to directly overwrite, and n to cancel the operation.
- -f: If the source directory or file specified to be moved has the same name as the target directory or file, it will not be asked, and the old file will be overwritten directly.
- -n: Do not overwrite any existing files or directories.
- -u: The move operation is performed only when the source file is newer than the target file or the target file does not exist.
- Use the mv command to copy the file1 file in the current directory test/ to the new directory /home/linaro, and enter the following command:
sudo mv file1 /home/linaro
rm
-
The rm command is used to delete a file or directory.
- parameter:
- -i: Ask for the confirmation one by one before deleting.
- -f: Even if the original file is set to read-only, it will be deleted directly without confirming one by one.
- -r: Delete the files in the directory and below one by one.
- To delete a file, you can use the rm command directly. If you delete a directory, you must choose the option "-r", for example:
sudo rm test.txt
-
- rm: delete the general file "test.txt"? y
sudo rm homework
-
- rm: cannot delete directory "homework": is a directory
sudo rm -r homework
-
- rm: delete the directory "homework"? y
reboot
reboot
- The reboot command is used to restart the computer. Changing the configuration of Tinker Board 2 often requires restarting.
-
parameter:
- -n : Do not write the memory data back to the hard disk before rebooting
- -w : don't actually reboot, just write the log to the /var/log/wtmp file
- -d : Do not write logs to the /var/log/wtmp file (-d is included with the -n parameter)
- -f : Force reboot, do not call shutdown command
- -i : Stop all network related devices before rebooting
- Restart
sudo reboot
shutdown
- We cannot power off the Tinker Board 2 directly for its memory as a temporary storage area, which would cause the data loss or the damage to the data on the SD card and the system would fail to boot.
-
parameter
- -t seconds : Set the shutdown procedure after a few seconds.
- -k : don't actually shut down, just send a warning message to all users.
- -r : reboot.
- -h : power off and halt
- -n : Do not use the normal program to power off, please use the forced method to close all the programs in execution and then power off by itself.
- -c : Cancel the shutdown action that is currently in progress.
- -f : Do not do fsck when power off (check Linux file system).
- -F : Force fsck action on shutdown.
- time : Set the shutdown time.
- message : The warning message sent to all users.
-
example
- Shut down now
sudo shutdown -h now
-
- Shutdown after specified 10 minutes
sudo shutdown -h 10
-
- restart the computer
sudo shutdown -r now
-
- No matter which command is used to close the system, root user permission is required. If the user uses a common user such as linaro, the sudo command can be used to temporarily obtain root permission.
pwd
The command displays the name of the current working directory: on Tinker Board 2, typing pwd will output something like /home/linaro.
head- The command displays the beginning of the file and it can be used with -n to specify the number of lines to display (default is 10), or with -c to specify the number of bytes.
head test.py -n 5
tail
- The tail shows the end of the file. -c bytes or -n lines specify the starting point in the file
df
- Used for df to show disk space available and used on mounted filesystems. Use df -h to see the output in a readable format, use M for MB instead of bytes.
df -h
zip
- The zip command is used to compress files, zip is a widely used compression program, and the suffix of compressed files is .zip.
If we are in the /home/linaro/waveshare directory and package all the files and folders in this directory as waveshare.zip in the current directory, you can execute the following command:
zip -q -r waveshare.zip *
uzip
- The unzip command is used to decompress zip files, and unzip is a decompression program for .zip compressed files.
unzip waveshare.zip -d user/
- Where -d is the directory where the specified file should be stored after decompression.
tar
- The tar command is a tool program used to create and restore backup files. It can add and unpack files in backup files.
- Compressed file:
tar -cvzf waveshare.tar.gz *
- unzip files:
tar -xvzf waveshare.tar.gz
apt
- apt (Advanced Packaging Tool) is a shell front-end package manager in Debian and Ubuntu.
- The apt command provides commands for finding, installing, upgrading, and removing a package, a group of packages, or even all packages, and the commands are concise and easy to remember.
- apt command execution requires super administrator privileges (root).
- apt common commands
- List all updatable software inventory command: sudo apt update
- Upgrade packages: sudo apt upgrade
- List updatable packages and version information: apt list --upgradeable
- Upgrade packages, delete the packages that need to be updated before upgrading: sudo apt full-upgrade
- Install the specified software command: sudo apt install <package_name>
- Install multiple packages: sudo apt install <package_1> <package_2> <package_3>
- Update the specified software command: sudo apt update <package_name>
- Display package specific information, such as: version number, installation size, dependencies, etc.: sudo apt show <package_name>
- Remove package command: sudo apt remove <package_name>
- Clean up unused dependencies and libraries: sudo apt autoremove
- Remove packages and configuration files: sudo apt purge <package_name>
- Find packages command: sudo apt search <keyword>
- List all installed packages: apt list --installed
- List version information of all installed packages: apt list --all-versions
- For example, we install nano editor
sudo apt install nano
Network
ifconfig
- Used to display the network configuration details of an interface on the current system when run with no arguments (ie) ifconfig.
- When connecting with SSH, you can find the IP address through ifconfig. For example, the wired IP address and wireless IP address of this device are: 192.168.15.103 and 192.168.15.102
hostname- The hostname command displays the current hostname of the system. When we use Tinker Board 2, we often need to use remote tools, and the default network configuration IP address adopts dynamic allocation, which will cause the problem of IP address uncertainty. When our Tinker Board 2 IP address changes, we can use the host name to log in.
1.Log in to Tinker Board 2 and modify the hosts file with the following command:
sudo nano /etc/hosts
-
- Replace lianro-alip with the name to be modified, such as waveshare, press Ctrl+s on the keyboard to save, and press Ctrl+x on the keyboard to exit:
- Modify the hostname file, and replace linaro with the name to be modified, such as waveshare, press Ctrl+x on the keyboard, press y on the keyboard, and press Enter to confirm:
sudo nano /etc/hostname
- After the modification is completed, restart Tinker Board 2:
sudo reboot
- You can also use sudo tinker-config to modify the hostname: Hostname
- We can also check the IP address with the following command:
hostname -I
Configuration
Connect WiFi
1. Switch to superuser mode
sudo su root
2. Turn on WiFi
nmcli r wifi
3. Scan WiFi
nmcli dev wifi
4. Connect to WiFi network
nmcli dev wifi connect wifi_name password "wifi_password"
5. If "successfully" is displayed, the wireless network is successfully connected, and the motherboard will automatically connect to the WiFi you specified next time it is powered on.

GPIO
GPIO Introduction
- GPIO: General-purpose input/output
-
Tinker Board 2 Pinout
- Power pins: 5v, 3.3v, GND (Ground).
- Regular GPIO control pins: The high and low levels of these pins can be controlled by programming.
- Special GPIO communication pins: SPI communication, 12C communication, TxD/RxD serial communication.
- Tinker Board 2 has a 40-pin expansion header
GPIO Operation
GPIO Number Computing
GPIO has 5 banks: from GPIO0 to GPIO4, each bank has 32 pins, named as follows:
GPIO0_A0 ~ A7 GPIO0_B0 ~ B7 GPIO0_C0 ~ C7 GPIO0_D0 ~ D7 GPIO1_A0 ~ A7 .... GPIO1_D0 ~ D7 .... GPIO4_D0 ~ D7
- For Linux 4.4 kernel, the number of GPIO can be calculated as follows, taking GPIO3_D7 (PIN40 on 40PIN GPIO) as an example
GPIO4_D5 = 3*32 + 3*8 + 7 = 127 (A=0, B=1, C=2, D=3)
- Set GPIO3_D7 output
cd /sys/class/gpio echo 127 > export cd gpio127 echo out > direction echo 1 > value # high output echo 0 > value # low output

IIC
Introduction
- I2C, full name is Inter-Integrated Circuit;
- It is a serial communication bus, using a multi-master-slave architecture, developed by Philips in the 1980s to allow motherboards and embedded systems to connect low-speed peripherals. The correct pronunciation of I2C is "I-squared-C" ("I-squared-C") or 'I-squared-C'
I2C hardware connection
- The I2C bus is very simple in physical connection, consisting of SDA (serial data line) and SCL (serial clock line) and pull-up resistors.
- The communication principle is to generate the signals required by the I2C bus protocol for data transmission by controlling the high and low levels of SCL and SDA.
- When the bus is idle, SCL and SDA will be pulled high by the pull-up resistor and kept high.
Through its physical connection, we can know that the I2C protocol is a serial and synchronous communication protocol
Feature
- Each device on the I2C bus will correspond to this unique I2C address, and some slave devices can change the I2C address through peripheral circuits.
- The master and slave devices use this address to determine which device to communicate with.
- Two-way data transmission is performed in units of bytes (8 bits) between the master device and the slave device on the I2C bus.
Detailed Protocol
- The I2C protocol stipulates that the transmission of data on the bus must take a starting signal as the start condition and an end signal as the stop condition of the transmission. The start and end signals are always generated by the master device (meaning that the slave device cannot initiate communication actively, all communications are initiated by the master device, the master can issue an inquiry command, and then wait for the communication from the slave device).
- When the bus is in an idle state, both SCL and SDA remain high. When SCL is high and SDA transitions from high to low, a start condition is generated; when the transfer is over, SCL is high and SDA is switched from A low-to-high transition indicates a stop condition.
- After the start condition is generated, the bus is in a busy state, the master-slave device of this data transfer occupies the bus, and other I2C devices cannot access the bus; after the stop condition is generated, the master-slave device of this data transfer will release the bus, the bus Idle again.
Data is transferred by bytes. The master device will transmit a data bit on the SDA line during the process of generating each clock pulse on the SCL line. When a byte is transmitted in the order of data bits from high to low, the slave device will pull down the SDA line. , and return a response bit to the master device, at which time it is considered that a byte has been truly transmitted. Of course, not all byte transfers must have an acknowledge bit. For example, when the slave device can no longer receive the data sent by the master device, the slave device will not return the acknowledge bit.

Phenomenon
- After running the program, the following data is output
SPI
Introduction
- SPI stands for Serial Peripheral Interface, which is a high-speed, full-duplex, synchronous communication bus.
- It works in a master-slave mode. In this mode, one master device usually corresponds to one or more slave devices. 4 lines are required for bidirectional data transmission, and 3 lines can be cut for one-way data transmission.
hardware connection
1.MOSI - Master output/slave input pin. This pin corresponds to the data sending pin of the master device and the data receiving pin of the slave device
2.MISO - Master input/slave output pin. This pin corresponds to the data receiving pin of the master device and the data sending pin of the slave device
3.SCLK - Synchronous clock, usually output by the master device.
4.CS – Select from device. Used to select slave devices. Its function is to allow the master device to communicate with a specific slave device, avoiding conflicts on the data lines.Working Method
- The Linux kernel uses a combination of CPOL and CPHA to represent the four working modes of the current SPI:
CPOL=0, CPHA=0 SPI_MODE_0 CPOL=0, CPHA=1 SPI_MODE_1 CPOL=1, CPHA=0 SPI_MODE_2 CPOL=1, CPHA=1 SPI_MODE_3
-
- CPOL: indicates the state of the initial level of the clock signal, 0 is a low level, and 1 is a high level.
- CPHA: Indicates which clock edge is sampled, 0 is the first clock edge sampling, 1 is the second clock edge sampling.
- The waveforms of the four working modes of SPI are as follows:
Enable SPI Interface
- Tinker Board 2 has a total of two spi channels, spi-1 (pin 13, pin 15, pin 16 and pin 18) and spi-5 (pin 19, pin 21, pin 23 and pin 18) 24), take the spi-5 as an example, the opening method is as follows:
1. Open config.txt:
sudo nano /boot/config.txt Change #intf:spi5=off to intf:spi5=on
2. After the modification is completed, press and hold Ctrl+s on the keyboard to save, Ctrl+x to exit, and restart the device:
sudo reboot
3. After the restart is complete, we enter the following command in the terminal to check that the spi-5 is successfully turned on:
ls /dev/spi*
CSI
- Tinker Board 2 supports Raspberry Pi Camera Module v1 (photosensitive chip is OV5647 of OmniVision) and Camera Module v2 (photosensitive chip is Sony IMX219):
- The system of Tinker Board 2 uses Camera Module v2 by default.
- If you are using Camera Module v1 (photosensitive chip OmniVision OV5647), the camera needs to be switched manually, please refer to Interfacing Options to enable it.
Hardware Connection
To test the camera, it is recommended to connect an HDMI screen or a DSI screen to Tinker Board 2
The interfaces of the CSI (camera) and DSI (display) on the Tinker Board 2 motherboard are similar, so be careful not to connect them wrongly when wiring. The CSI camera interface is next to the Power interface.
Enable Camera
Since tinkerboard has installed Gstreamer by default, we can use it directly.
1. First we check if the camera is connected successfullyv4l2-ctl -V
2.Open the terminal directlygst-launch-1.0 v4l2src ! video/x-raw,format=NV12,width=640,height=480 ! videoconvert ! autovideosink

User Guides of Raspberry Pi
Hardware Connection
1. Use the 22Pin to 15Pin FPC cable to connect the DSI interface of the 8inch DSI LCD to the DSI interface of the Tinker Board 2.
2. For ease of use, Tinker Board 2 can be screwed to the back of the 8inch DSI LCD and assembled with copper posts. (The Tinker Board 2GPIO interface will supply power to the LCD through the thimble)
As shown below:Backlight Control
- Enter the following command in the terminal to control the backlight brightness:
sudo su root echo X > /sys/class/backlight/panel_backlight/brightness
- Where X represents any number from 0 to 255. 0 means the backlight is the darkest, and 255 means the backlight is the brightest. E.g:
echo 100 > /sys/class/backlight/panel_backlight/brightness echo 0 > /sys/class/backlight/panel_backlight/brightness echo 255 > /sys/class/backlight/panel_backlight/brightness

Turn on bf16s
Open the `sample/ncnn/src/YoloDet.cpp` file and add following inside the `YoloDet::init` function
net.opt.use_packing_layout = true; net.opt.use_bf16_storage = true;
Finally, set the processor again to achieve the best performance.

If there's any failure encountered during the OS writing process on Tinker Board S, you can either recover using the UMS from eMMC if eMMC’s U-Boot still workable, or re-writing the OS using UMS from a microSD card if there's a problem booting from eMMC's U-bbot.
Below are the procedures:
UMS from eMMC
eMMC’s U-Boot still workable and had built-in the UMS function.
Can use the UMS mode to re-flash
- The eMMC need have a workable U-Boot.
- Connect Tinker Board S to PC via Micro-USB.
-
It would booting & create the partitions like a USB drive.
(please remove other extend device on board) - Just flash as the old way.
UMS from SD card
eMMC’s U-Boot is broken to booting or not built-in the UMS function (e.g. 3rd party custom image).
Can trigger the UMS mode from SD card
- Flash the Image (with UMS’s U-Boot) to SD card.
- Install the SD card to Tinker Board S.
-
Plug the Jumper on the Maskrom mode.
(force to boot from SD, jump out the eMMC) - Connect Tinker Board S to PC via Micro-USB, then there will become as USB mass storage on your computer
- Then you can flash the eMMC as usual, the old way. (e.g.: win32DiskImager, etcher and so on)
- After finish the image flash, unplug the USB from PC and then put the jumper at the "no function" mode.
- Plug in the AC adaptor to boot the device
-
It would boot successfully & create the partitions like a USB drive.
(please remove other extend device on board)
Without UMS mode
Recovery from SD’s image system & without the PC mode (ready on TinkerOS v2.0.4 or above)
-
Plug the Jumper on the Maskrom mode.
(force to boot from SD, jump out the eMMC) - Flash the Image (any can bootable) to SD card.
- Plug the SD card to Tinker Board S.
- Booting the Tinker Board S.
- It would booting to the RootFS.
- Then dd or other ways to flash new image file to eMMC(mmcblk1).
