    /dev/mmcblk0

  1. Then we can use the dd command to clear the eMMC. Note that after the of= parameter, please fill in the output result of the above command
  2. orangepi@orangepi:~/Desktop$ sudo dd bs=1M if=/dev/zero of=/dev/mmcblk0 count=1000 status=progress

    orangepi@orangepi:~/Desktop$ sudo sync

  1. Then you can use the dd command to burn the Linux image of the development board into the eMMC

    1. In the following command, the if= parameter is followed by the full path where the Linux image is stored + the name of the Linux image (such as the name of /home/orangepi/Desktop/Linux image). Because we have entered the path of the Linux image above, we only need to fill in the name of the Linux image.

    2. Please do not copy the Linux image name in the following command, but replace it with the actual image name (because the version number of the image may be updated).

    3. sudo dd bs=1M if=Orangepi3b_x.x.x_debian_bullseye_desktop_xfce_Linux5.10.160.img of=/dev/mmcblk0 status=progress

      sudo sync

      Note, if you upload a .7z or .xz Linux image compressed file, please remember to decompress it before using the dd command to burn.


      The detailed description of all parameters of the dd command and more usage can be viewed by executing the man dd command in the Linux system.

  1. When the same system is programmed in the TF card and NVMe SSD, if both the TF card and NVMe SSD are inserted into the development board, then power on and start the development board, and u-boot will give priority to starting the system in the TF card. However, since the systems in the TF card and the NVMe SSD are exactly the same, the UUIDs of the /boot partition and the rootfs partition in the two storage devices are also the same, which may cause the partition in the NVMe SSD to be loaded when the TF card starts. Running the script below resolves this issue.
  2. orangepi@orangepi:~$ sudo fix_mmc_ssd.sh

    Exactly the same system means that the image name is exactly the same. Even if they are all Debian11 systems, the versions are different.

Network connection test

Ethernet port test

  1. First, insert one end of the network cable into the Ethernet interface of the development board, and connect the other end of the network cable to the router, and ensure that the network is unblocked
  2. After the system starts, it will automatically assign an IP address to the Ethernet card through DHCP, No other configuration is required
  3. The command to view the IP address in the Linux system of the development board is as follows

orangepi@orangepi:~$ ip addr show eth0

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

link/ether 4a:fe:2b:3d:17:1c brd ff:ff:ff:ff:ff:ff
inet 192.168.1.150/24 brd 192.168.1.255 scope global dynamic noprefixroute eth0
valid_lft 43150sec preferred_lft 43150sec
inet6 fe80::9a04:3703:faed:23be/64 scope link noprefixroute
valid_lft forever preferred_lft forever

When using ifconfig to view the IP address, if the following information is displayed, it is because sudo is not added. The correct command is: sudo ifconfig


orangepi@orangepi:~$ ifconfig

Command 'ifconfig' is available in the following places

  • /sbin/ifconfig
  • /usr/sbin/ifconfig

The command could not be located because '/sbin:/usr/sbin' is not included in the PATH environment variable.

This is most likely caused by the lack of administrative privileges associated with your user account.

ifconfig: command not found

There are three ways to check the IP address after the development board starts:

1. Connect the HDMI display, then log in to the system and use the ip addr show eth0 command to view the IP address

2. Enter the ip addr show eth0 command in the debugging serial terminal to view the IP address

3. If there is no debugging serial port and no HDMI display, you can also check the IP address of the development board's network port through the router's management interface. However, in this method, some people often cannot see the IP address of the development board normally. If you can't see it, the debug method looks like this:

  1. First check whether the Linux system has started normally. If the green light of the development board is blinking, it is generally started normally. If only the red light is on, it means that the system has not started normally;

  2. Check whether the network cable is plugged in tightly, or try another network cable;

  3. Try another router (I have encountered many problems with the router, such as the router cannot assign the IP address normally, or the IP address has been assigned normally but cannot be seen in the router);

  4. If there is no router to replace, you can only connect to an HDMI display or use the debugging serial port to view the IP address


In addition, it should be noted that the development board DHCP automatically assigns an IP address without any settings.

  1. The command to test the network connectivity is as follows, the ping command can be interrupted through the shortcut key of Ctrl+C
  2. orangepi@orangepi:~$ ping www.baidu.com -I eth0

WIFI connection test

Please do not connect to WIFI by modifying the /etc/network/interfaces configuration file. There will be problems connecting to the WIFI network in this way.

The server image connects to WIFI through commands

When the development board is not connected to Ethernet, not connected to HDMI display, but only connected to the serial port, it is recommended to use the commands demonstrated in this section to connect to the WIFI network. Because nmtui can only display characters in some serial port software (such as minicom), and cannot display the graphical interface normally. Of course, if the development board is connected to an Ethernet or HDMI display, you can also use the commands demonstrated in this section to connect to the WIFI network.

  1. First log in to the Linux system, there are the following three ways

    1. If the development board is connected with a network cable, you can remotely log in to the Linux system through ssh

    2. If the development board is connected to the debugging serial port, you can use the serial port terminal to log in to the Linux system

    3. If the development board is connected to the HDMI display, you can log in to the Linux system through the terminal displayed on the HDMI

  2. First use the nmcli dev wifi command to scan the surrounding WIFI hotspots

  3. orangepi@orangepi:~$ nmcli dev wifi

    Pi3b-img176.png

  1. Then use the nmcli command to connect to the scanned WIFI hotspot, where:
  2. a. wifi_name needs to be replaced with the name of the WIFI hotspot you want to connect to
    b. wifi_passwd needs to be replaced with the password of the WIFI hotspot you want to connect to

    orangepi@orangepi:~$ nmcli dev wifi connect wifi_name password wifi_passwd

    Device 'wlan0' successfully activated with 'cf937f88-ca1e-4411-bb50-61f402eef293'.

How to install wiringOP

Note that wiringOP has been pre -installed in the Linux image released by Orange Pi. Unless wiringOP's code is updated, it is not necessary to re -download and install. Just use it directly.


The storage path of the compiled wiringOP's Deb is wrapped in Orangepi-Build:

orangepi-build/external/cache/debs/arm64/wiringpi_x.xx.deb


After entering the system, you can run the gpio readall command. If you can see the output below, it means that wiringOP is pre -installed and can be used normally.

Pi3b-img258-1.png

wiringOP is currently mainly adapted to the functions of setting GPIO port input and output, setting GPIO port output high and low levels, and setting up and down pull-down resistors. Functions such as hardware PWM are not available.

  1. Download the code of wiringOP

orangepi@orangepi:~$ sudo apt update

orangepi@orangepi:~$ sudo apt install -y git

orangepi@orangepi:~$ git clone https://github.com/orangepi-xunlong/wiringOP.git -b next

Note that Orange Pi 3B needs to download the code of the wiringOP next branch, please don't miss the parameter of -b next.


If there is a problem with the download code from GitHub, you can use the wiringOP source code that comes with the Linux image directly, and the storage location is: /usr/src/wiringOP

  1. Compile and install wiringOP
  2. orangepi@orangepi:~$ cd wiringOP

    orangepi@orangepi:~/wiringOP$ sudo ./build clean

    orangepi@orangepi:~/wiringOP$ sudo ./build

  1. Test the output of the GPIO Readall command as follows
  2. Pi3b-img258-1.png

40Pin interface GPIO, I2C, UART, SPI, and PWM test

Note that if you need to set overlays to open multiple configurations at the same time, please use a space to write in one line like the following space.

orangepi@orangepi:~$ sudo vim /boot/orangepiEnv.txt

overlays=spi3-m0-cs0-spidev i2c2-m1 i2c3-m0 uart7-m2 uart9-m2 pwm11-m1

40pin GPIO port test

The Linux system released by Orange Pi has a pre -installed blink_all_gpio program. This program will set up all 28 GPIO ports in 40pin to switch high and low levels.


After running the blink_all_gpio program, when using a multimeter to measure the level of the GPIO port, you will find that the GPIO pin will be switched between 0 and 3.3v. Use this program to test whether the GPIO port can work normally


The method of running blink_all_gpio program is shown below:

orangepi@orangepi3b:~$ sudo blink_all_gpio         #Remember to add Sudo permissions

[sudo] password for orangepi:        #You need to enter password here

  1. There are a total of 28 GPIO ports in the 40pins of the development board that can be used. The following uses pin 7—the corresponding GPIO is GPIO4_C3——the corresponding wPi serial number is 2—as an example to demonstrate how to set the high and low levels of the GPIO port
Pi3b-img259-1.png
  1. First set the GPIO port as the output mode, the third parameter needs to enter the serial number of the wPi corresponding to the pins
  2. root@orangepi:~/wiringOP# gpio mode 2 out

  1. Then set the GPIO port to output the low level. After setting, you can use the value of the voltage of the pins with a multimeter. If it is 0v, it means that the low level flat is successful
  2. root@orangepi:~/wiringOP# gpio write 2 0

    Using GPIO Readall, you can see the value of the No. 7 pin (V) to 0

    Pi3b-img260.png

  1. Then set the GPIO port to output a high level. After setting, you can use a multimeter to measure the voltage value of the pin. If it is 3.3v, it means that the high level is set successfully.
  2. root@orangepi:~/wiringOP# gpio write 2 1

    Using GPIO Readall, you can see the value of No. 7 pin (v) into 1

    Pi3b-img261-1.png

  1. The setting method of other pins is similar, just modify the serial number of wPi to the corresponding serial number of the pin

40pin GPIO port pull-down resistance setting method

Note that the 4 GPIO pins below Orange Pi 3B are invalid because there are 3.3V on the outside, so setting drop-down is invalid. Other pins can be set normally

Pi3b-img262-1.png
  1. Below the No. 11 pin—corresponding to GPIO 3_C6-corresponding wPi serial number 5—to demonstrate how to set up and down pull-down resistance of the GPIO port
Pi3b-img263-1.png
  1. First of all, you need to set the GPIO port as the input mode. The third parameter needs to enter the serial number of the wPi corresponding to the pins
  2. root@orangepi:~/wiringOP# gpio mode 5 in

  1. After the setting is set to input mode, execute the following command to set the GPIO port as the pull-down mode
  2. root@orangepi:~/wiringOP# gpio mode 5 up

  1. Then enter the following command to read the level of the GPIO port. If the level is 1, it means that the drawing mode is successful
  2. root@orangepi:~/wiringOP# gpio read 5

    1

  1. Then execute the following command to set the GPIO port as the drop-down mode
  2. root@orangepi:~/wiringOP# gpio mode 5 down

  1. Then enter the following command to read the level of the GPIO port. If the level is 0, it means that the drop-down mode is set successfully
  2. root@orangepi:~/wiringOP# gpio read 5

    0

Pi3b-img270-1.png
  1. In the linux system, the PWM in the 40 pin is turned off by default, and it needs to be turned on manually before it can be used. The detailed steps are as follows:

    1. First run orangepi-config, normal users remember to add sudo permission

      orangepi@orangepi:~$ sudo orangepi-config

    2. Then select System

      Pi3b-1.png

    3. Then select Hardware

      Pi3b-2.png

    4. Then use the arrow keys on the keyboard to navigate to the position shown in the figure below, and then use the space to select the PWM configuration you want to open

      Pi3b-3-4.png

    5. Then select <Save> to save

      Pi3b-4.png

    6. Then select <Back>

      Pi3b-5.png

    7. Then select <Reboot> to restart the system to make the configuration take effect

      Pi3b-6.png

  1. After opening a pwm, there will be an extra pwmchipX in /sys/class/pwm/ (X is a specific number), for example, after opening pwm11, check the pwmchipX under /sys/class/pwm/ one becomes two
  2. orangepi@orangepi:~$ ls /sys/class/pwm/

    pwmchip0 pwmchip1

  1. Which pwmchip above corresponds to pwm11, let's check the output of the ls /sys/class/pwm/ -l command first, as shown below:

  2. Then it can be known from the table below that the base address of the pwm11 register is fe6f0030, and then look at the output of the ls /sys/class/pwm/ -l command, you can see that pwmchip1 is linked to fe6f0030.pwm, so pwm11 corresponds to pwmchip as pwmchip1

  3. Pi3b-img271.png

  1. Then use the following command to make pwm11 output a 50Hz square wave (please switch to the root user first, and then execute the following command)
  2. root@orangepi:~# echo 0 > /sys/class/pwm/pwmchip1/export

    root@orangepi:~# echo 20000000 > /sys/class/pwm/pwmchip1/pwm0/period

    root@orangepi:~# echo 1000000 > /sys/class/pwm/pwmchip1/pwm0/duty_cycle

    root@orangepi:~# echo 1 > /sys/class/pwm/pwmchip1/pwm0/enable

    Pi3b-img272.png

  3. The test method of pwm11 demonstrated above is similar to other pwm test methods.

40pin GPIO port test

wiringOP-Python is the same as wiringOP, you can also determine which GPIO pin to operate by specifying the wPi number, because there is no command to check the wPi number in wiringOP-Python, so you can only check the board wPi number and physical Correspondence between pins.

Pi3b-img258.png
  1. Below the No. 7 pin — corresponding to GPIO4_a4 -corresponding WPI serial number 2 -to demonstrate how to set the height of the GPIO port
Pi3b-img259.png
  1. The steps of the command test are shown below directly:

    1. First set the GPIO port to the output mode. The first parameter of the pinMode function is the serial number of the wpi corresponding to the pin, and the second parameter is the GPIO mode
    2. root@orangepi:~/wiringOP-Python# python3 -c "import wiringpi; \

      from wiringpi import GPIO; wiringpi.wiringPiSetup() ; \

      wiringpi.pinMode(2, GPIO.OUTPUT) ; "

    1. Then set the GPIO port output low level. After setting, you can use the voltage of the voltage of the universal meter to measure the pins. If it is 0V, it means that the low -power flat is successful
    2. root@orangepi:~/wiringOP-Python# python3 -c "import wiringpi; \

      from wiringpi import GPIO; wiringpi.wiringPiSetup() ;\

      wiringpi.digitalWrite(2, GPIO.LOW)"

    1. Then set the GPIO port output high level. After setting, you can use the value of the voltage of the pins with a multimeter. If it is 3.3V, it means that the high -power flat is successful.
    2. root@orangepi:~/wiringOP-Python# python3 -c "import wiringpi; \

      from wiringpi import GPIO; wiringpi.wiringPiSetup() ;\

      wiringpi.digitalWrite(2, GPIO.HIGH)"

  1. The steps of testing in the command line of Python3 are shown below:

    1. First use the Python3 command to enter the command line mode of Python3
    2. root@orangepi:~# python3

    1. Then import the Python module of WiringPi
    2. >>> import wiringpi

      >>> from wiringpi import GPIO

    1. Then set the GPIO port as the output mode. The first parameter of the pinMode function is the serial number of the wpi corresponding to the pin, and the second parameter is the GPIO mode.
    2. >>> wiringpi.wiringPiSetup()

      0

      >>> wiringpi.pinMode(2, GPIO.OUTPUT)

    1. Then set the GPIO port output low level. After setting, you can use the value of the voltage of the pins with a multimeter. If it is 0V, it means that the low -power flat is set.
    2. >>> wiringpi.digitalWrite(2, GPIO.LOW)

    1. Then set the GPIO port output high level. After setting, you can use the value of the voltage of the pins with a multimeter. If it is 3.3V, it means that the high -power flat is successful
    2. >>> wiringpi.digitalWrite(2, GPIO.HIGH)

  1. Wiringop-Python Sets GPIO high and low levels in the Python code. For reference to the blink.py test program in Examples, the voltage of the blink.py test program will set up the voltage of all GPIO ports in the development board 40 PIN
  2. root@orangepi:~/wiringOP-Python# cd examples

    root@orangepi:~/wiringOP-Python/examples# ls blink.py

    blink.py

40pin SPI test

  1. From the schematic diagram of the 40pin interface, the SPI available for Orange Pi 3B is spi3
Pi3b-img264.png

In the Linux system, the spi3 in 40pin is closed by default, and it needs to be opened manually to use.


Add the configuration of the red font part below to the /boot/orangepiEnv.txt, and then restart the Linux system to open the spi4.


orangepi@orangepi:~$ sudo vim /boot/orangepiEnv.txt

overlays=spi3-m0-cs0-spidev

  1. First check whether there is a spidev3.0 device node in the Linux system. If it exists, it means that the SPI3 has been set and can be used directly
  2. orangepi@orangepi:~$ ls /dev/spidev3.0

    /dev/spidev3.0

  1. You can then use the spi back function under the spidev_test.py program in Examples. The spidev_test.py program needs to specify the following two parameters:

    1. --channel: Specify the channel number of SPI

    2. --port: Specify the port number of SPI

  2. Do not pick up the two pins of the SPI3 MOSI and MISO in short, and run the output result of the spidev_test.py as shown below. You can see that the data of TX and RX are inconsistent

  3. root@orangepi:~/wiringOP-Python# cd examples

    root@orangepi:~/wiringOP-Python/examples# python3 spidev_test.py \

    --channel 3 --port 0

    spi mode: 0x0

    max speed: 500000 Hz (500 KHz)

    Opening device /dev/spidev3.0

    TX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D |......@.......…|

    RX | FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF |.............….|

  1. Then use the TXD (No. 19 pins in the 40Pin interface) and RXD (No. 21 pins in the 40pin interface) of the DuPont line short connection SPI3. Like sending and receiving data, it means that the SPI3 loop test is normal
  2. root@orangepi:~/wiringOP-Python# cd examples

    root@orangepi:~/wiringOP-Python/examples# python3 spidev_test.py \

    --channel 3 --port 0

    spi mode: 0x0

    max speed: 500000 Hz (500 KHz)

    Opening device /dev/spidev3.0

    TX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D |......@.......…|

    RX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D |......@.......…|

40pin I2C test

  1. As can be seen from the table below, the I2C available for Orange Pi 3B is I2C2, I2C3, and I2C4 a total of three groups of I2C bus
  2. Pi3b-img266.png

    It can be seen from the above table that I2C4_M0 and SPI3_M0 are pins. The two cannot be opened at the same time. I2C3_M0 and UART3_M0 are also reused. The two cannot be opened at the same time

    In the Linux system, the I2C in 40Pin is closed by default, and it needs to be opened manually to use.


    Add the configuration of the red font part below to the/boot/orangepiEnv.txt, and then restart the Linux system to open the I2C2, i2C3, and I2C4 at the same time. If you only need to open one, then fill in one.


    orangepi@orangepi:~$ sudo vim /boot/orangepiEnv.txt

    overlays=i2c2-m1 i2c3-m0 i2c4-m0

  1. After starting the Linux system, first confirm the I2C device node under/dev.
  2. orangepi@orangepi:~# ls /dev/i2c-*

    /dev/i2c-0      /dev/i2c-2      /dev/i2c-3      /dev/i2c-4      /dev/i2c-6

  1. Then connect a I2C device on the I2C pin of the 40PIN connector. Here is an example of the DS1307 RTC module.
  2. i2c2-m1 i2c3-m0 i2c4-m0
    Sda Pin Corresponding to No. 3 pin Corresponding to No. 27 pin Corresponding to No. 19 pin
    Sck Pin Corresponding to No. 5 pin Corresponding to No. 28 pin Corresponding to No. 23 pin
    Vcc Pin Corresponding to No. 1 pin Corresponding to No. 1 pin Corresponding to No. 1 pin
    Gnd Pin Corresponding to No. 6 pin Corresponding to No. 6 pin Corresponding to No. 6 pin

    Pi3b-img273.png

  1. Then use the i2cdetect -y command If the address of the connected I2C device can be detected, it means that the I2C can be used normally
  2. orangepi@orangepi:~$ sudo i2cdetect -y 2 #i2c2 command

    orangepi@orangepi:~$ sudo i2cdetect -y 3 #i2c3 command

    orangepi@orangepi:~$ sudo i2cdetect -y 4 #i2c4 command

    Pi3b-img274.png

  1. You can then run the time of the ds ds1307.py test program in examples to read the RTC time
  2. root@orangepi:~/wiringOP-Python# cd examples

    root@orangepi:~/wiringOP-Python/examples# python3 ds1307.py --device \

    "/dev/i2c-4"

40pin's UART test

  1. As can be seen from the table below, the UART available for Orange Pi 3B is UART3, UART7 and UART9. There are three sets of UART bus
Pi3b-img268.png

As can be seen from the above table, I2C3_M0 and UART3_M0 are reused by pins, and the two cannot be opened at the same time

In the Linux system, the UART in 40pin is closed by default, and it needs to be opened manually to use.

Add the configuration of the red font part below to the /boot/orangepiEnv.txt, and then restart the Linux system to open the UART3, UART7, and UART9 at the same time. If you only need to open one, you can fill in one

orangepi@orangepi:~$ sudo vim /boot/orangepiEnv.txt

overlays=uart3-m0 uart7-m2 uart9-m2

  1. After entering the Linux system, first confirm whether there is a device node corresponding to UART under/dev
  2. orangepi@orangepi:~# ls /dev/ttyS*

    /dev/ttyS1      /dev/ttyS3      /dev/ttyS7      /dev/ttyS9

  1. Then start testing the UART interface, and first use the RX and TX of the UART interface to be tested by DuPont
  2. uart3 uart7 uart9
    Tx Pin Corresponding to the 28 pin Corresponding to the 16 pin Corresponding to the 29 pin
    Rx Pin Corresponding to the 27 pin Corresponding to the 15 pin Corresponding to the 7 pin
  1. Use the serialTest.py program in Examples to test the loop function of the serial port. If you can see the printing below, it means that the serial communication is normal

    1. Test UART3
    2. root@orangepi:~/wiringOP-Python/examples# python3 serialTest.py --device \

      "/dev/ttyS3"


      Out: 0: -> 0

      Out: 1: -> 1

      Out: 2: -> 2

      Out: 3: -> 3

      Out: 4:^C

      exit

    1. Test UART7
    2. root@orangepi:~/wiringOP-Python/examples# python3 serialTest.py --device \

      "/dev/ttyS7"


      Out: 0: -> 0

      Out: 1: -> 1

      Out: 2: -> 2

      Out: 3: -> 3

      Out: 4:^C

      exit

    1. Test UART9
    2. root@orangepi:~/wiringOP-Python/examples# python3 serialTest.py --device \

      "/dev/ttyS9"


      Out: 0: -> 0

      Out: 1: -> 1

How to remotely log in to the Linux system desktop method

Ubuntu Gnome Wayland image does not support Nomachine and VNCs introduced here to remotely log in to the desktop.

Use nomachine remote login

Make sure the Ubuntu or Debian system installed on the development board is a desktop version. In addition, nomachine also provides detailed documents. It is strongly recommended to read this document to be familiar with the use of nomachine. The document links are shown below:

https://knowledgebase.nomachine.com/DT10R00166

Nomachine supports Windows, Mac, Linux, iOS, and Android platforms, so we can remotely log in to control Orange PI development boards through Nomachine on multiple devices. The following demonstrates the Linux system desktop of the Orange PI development board through Nomachine in Windows. For installation methods for other platforms, please refer to the official documentation of Nomachine.

Before operation, please ensure that the Windwos computer and the development board are in the same local area network, and can log in to the Ubuntu or Debian system that can log in to the development board normally.

  1. First download the nomachine software Linux ARM64 DEB version of the installation package, and then install it in the Linux system of the development board

    1. Since RK3566 is a SOC of the ARMV8 architecture, the system we use is Ubuntu or Debian, so you need to download NoMachine for ARM ARMv8 DEB installation package here. The download link is shown below:
    2. Note that this download link may change, please recognize the DEB package of the ARMV8/ARM64 version.

      https://downloads.nomachine.com/download/?id=118&distro=ARM

How to install kernel header files

  1. The Linux image released by OPi comes with the deb package of the kernel header file by default, and the storage location is /opt/

orangepi@orangepi:~$ ls /opt/linux-headers*

/opt/linux-headers-legacy-rockchip-rk356x_x.x.x_arm64.deb

  1. Use the following command to install the deb package of the kernel header file
  2. The name of the kernel header file deb package needs to be replaced with the actual name, please do not copy it.

    orangepi@orangepi:~$ sudo dpkg -i /opt/linux-headers-legacy-rockchip-rk356x_1.x.x_arm64.deb

  1. After installation, you can see the folder where the kernel header files are located under /usr/src
  2. orangepi@orangepi:~$ ls /usr/src

    linux-headers-5.10.160-rockchip-rk356x

  1. Then you can write a hello kernel module to test the kernel header file

    1. First write the code of the hello kernel module, as follows:
    2. orangepi@orangepi:~$ vim hello.c

      #include <linux/init.h>

      #include <linux/module.h>


      static int hello_init(void)

      {

      printk("Hello Orange Pi -- init\n");


      return 0;

      }

      static void hello_exit(void)

      {

      printk("Hello Orange Pi -- exit\n");


      return;

      }


      module_init(hello_init);

      module_exit(hello_exit);


      MODULE_LICENSE("GPL");

    1. Then write the Makefile for compiling the hello kernel module, as follows:
    2. orangepi@orangepi:~$ vim Makefile

      ifneq ($(KERNELRELEASE),)

      obj-m:=hello.o

      else

      KDIR :=/lib/modules/$(shell uname -r)/build

      PWD :=$(shell pwd)

      all:

      make -C $(KDIR) M=$(PWD) modules

      clean:

      rm -f *.ko *.o *.mod.o *.mod *.symvers *.cmd *.mod.c *.order

      endif

    1. Then use the make command to compile the hello kernel module. The output of the compilation process is as follows:
    2. If there is a problem with compiling the code you copied here, please go to the official tool to download the source code and upload it to the Linux system of the development board for testing.

      Pi3b-img352.png

      orangepi@orangepi:~$ make

      make -C /lib/modules/5.10.160-rockchip-35xx/build M=/home/orangepi modules

      make[1]: Entering directory '/usr/src/linux-headers-5.10.160-rockchip-rk35xx'

      CC [M] /home/orangepi/hello.o
      MODPOST /home/orangepi/Module.symvers
      CC [M] /home/orangepi/hello.mod.o
      LD [M] /home/orangepi/hello.ko

      make[1]: Leaving directory '/usr/src/linux-headers-5.10.160-rockchip-rk35xx'

    1. After compiling, the hello.ko kernel module will be generated
    2. orangepi@orangepi:~$ ls *.ko

      hello.ko

    1. Use the insmod command to insert the hello.ko kernel module into the kernel
    2. orangepi@orangepi:~$ sudo insmod hello.ko

    1. Then use the demsg command to view the output of the hello.ko kernel module. If you can see the output below, it means that the hello.ko kernel module is loaded correctly.
    2. orangepi@orangepi:~$ dmesg | grep "Hello"

      [ 2871.893988] Hello Orange Pi -- init

    1. Use the rmmod command to uninstall the hello.ko kernel module
    2. orangepi@orangepi:~$ sudo rmmod hello

      orangepi@orangepi:~$ dmesg | grep "Hello"

      [ 2871.893988] Hello Orange Pi -- init

      [ 3173.800892] Hello Orange Pi -- exit

Use of the Raspberry PI's 5-inch screen

Assembly method of Raspberry PI 5-inch screen

  1. First prepare the required accessories

    1. Raspberry PI 5-inch MIPI LCD display + touch screen
    2. Pi3b-img353.png

    1. 15pin MIPI cable
    2. Pi3b-img354.png

  1. Then connect the 15pin MIPI cable to the Raspberry PI 5-inch screen in the way shown below (note the orientation of the insulation surface)
  2. Pi3b-img355.png

  1. Finally connect to the LCD interface of the Orange Pi 3B development board
  2. Pi3b-img356.png

Open the Raspberry PI 5-inch screen configuration method

  1. The Linux image does not open the 5-inch screen of the Raspberry PI by default. If you need to use the 5-inch screen of the Raspberry PI, you need to open it manually.

  2. The steps to open the mipi lcd configuration are as follows:

    1. First run orangepi-config, ordinary users remember to add sudo permission
    2. orangepi@orangepi:~$ sudo orangepi-config

    1. Then select System
    2. Pi3b-img357.png

    1. Then select Hardware
    2. Pi3b-img358.png

    1. Then use the arrow keys on the keyboard to locate the Rasp-7inch-touchscreen, and then use the space button to check
    2. Pi3b-img359.png

    1. Then select <Save> to save
    2. Pi3b-img360.png

    1. Then select <Back>
    2. Pi3b-img361.png

    1. Then select <Reboot> to restart the system for the configuration to take effect
    2. Pi3b-img362.png

      The above settings will eventually add the configuration of overlays=raspi-7inch-touchscreen to /boot/orangepiEnv.txt. After setting, you can check it first. If this configuration does not exist, then there is a problem with the settings.

      If you find it troublesome to use orangepi-config, you can also use the vim editor to open /boot/orangepiEnv.txt, and then add the configuration of overlays=raspi-7inch-touchscreen is also possible.


      orangepi@orangepi:~$ cat /boot/orangepiEnv.txt | grep "raspi"

      overlays=raspi-7inch-touchscreen #Sample configuration

  1. After startup, you can see the lcd screen display as follows:
  2. Pi3b-img363.png

The method of server version image rotation display direction

  1. Add extraargs=fbcon=rotate:the direction to rotate in /boot/orangepiEnv.txt This line configuration can set the direction displayed by the server version of the Linux system, where the number after fbcon=rotate: can be set as:

    1. 0: normal screen (default is landscape)

    2. 1: Turn clockwise 90 degrees

    3. 2: Flip 180 degrees

    4. 3: Turn clockwise 270 degrees

    5. orangepi@orangepi:~$ sudo vim /boot/orangepiEnv.txt

      overlays=lcd1

      extraargs=cma=64M fbcon=rotate:3

      Note that if there is the line extraargs=cma=64M in /boot/orangepiEnv.txt by default, the configuration fbcon=rotate:3 can be added after extraargs=cma=64M (separated by spaces).

  1. Then restart the Linux system and you can see that the direction displayed on the LCD screen has been rotated

Method of rotating display and touch direction of desktop version image

  1. First open Display Settings in Linux
Pi3b-img364.png
  1. Then select the direction you want to rotate in Rotation

    1. None: no rotation

    2. Left: rotate left 90 degrees

    3. Inverted: Flip up and down, which is equivalent to rotating 180 degrees

    4. Right: rotate right 90 degrees

    5. Pi3b-img365.png

  1. Then click Apply
  2. Pi3b-img366.png

  1. Then select Keep this configuration
  2. Pi3b-img367.png

  1. At this point, the screen display has been rotated, and then close the Display program

  2. The above steps will only select the display direction, and will not rotate the direction of the touch. Use the set_lcd_rotate.sh script to rotate the direction of the touch. After the script is set, it will automatically restart, and then you can test whether the touch has been used normally.

    1. None: no rotation
    2. orangepi@orangepi:~$ set_lcd_rotate.sh none

    1. Left: rotate left 90 degrees
    2. orangepi@orangepi:~$ set_lcd_rotate.sh left

    1. Inverted: Flip up and down, which is equivalent to rotating 180 degrees
    2. orangepi@orangepi:~$ set_lcd_rotate.sh inverted

    1. Right: rotate right 90 degrees
    2. orangepi@orangepi:~$ set_lcd_rotate.sh right

      The set_lcd_rotate.sh script mainly does four things:


      1. Rotate the direction displayed by the framebuffer

      2. Rotate the direction of the touch

      3. Turn off the boot logo

      4. Restart the system


      Rotating the touch direction is achieved by adding the line Option "TransformationMatrix" "x x x x x x x x x" to /usr/share/X11/xorg.conf.d/40-libinput.conf Where "x x x x x x x x x" is configured differently for different directions.

  1. Touch rotation reference
  2. https://wiki.ubuntu.com/X/InputCoordinateTransformation

  1. By default, the switch logo will only be displayed in the desktop version of the system
  2. Set the bootlogo variable to false in /boot/orangepiEnv.txt to turn off the switch logo

orangepi@orangepi:~$ vim /boot/orangepiEnv.txt

verbosity=1

bootlogo=false

  1. Set the bootlogo variable to true in /boot/orangepiEnv.txt to enable the switch logo
  2. orangepi@orangepi:~$ vim /boot/orangepiEnv.txt

    verbosity=1

    bootlogo=true

  1. The location of the boot logo image in the Linux system is
  2. /usr/share/plymouth/themes/orangepi/watermark.png

  1. After replacing the boot logo picture, you need to run the following command to take effect
  2. orangepi@orangepi:~$ sudo update-initramfs -u

How to use the ZFS file system

The latest version of Ubuntu20.04, Ubuntu22.04, Debian11 and Debian12 desktop version systems have pre-installed zfs, you can use it directly.

The pre-installed zfs version in Ubuntu20.04 and Ubuntu22.04 desktop systems is 2.1.6.

The pre-installed zfs version in Debian11 and Debian12 desktop systems is 2.1.11.

After the system starts, please first confirm whether the zfs kernel module has been loaded. If you can see zfs-related content using the lsmod command, it means that the system has pre-installed zfs.

orangepi@orangepi:~$ lsmod | grep "zfs"

zfs                     2801664     0

zunicode             327680     1   zfs

zzstd                  471040     1   zfs

zlua                    139264     1   zfs

zcommon             69632     1   zfs

znvpair                 61440     2   zfs,zcommon

zavl                      16384     1   zfs

icp                     221184     1   zfs

spl                       77824     6   zfs,icp,zzstd,znvpair,zcommon,zavl

How to install ZFS

Before installing zfs, please make sure that the Linux image used is the latest version. In addition, if zfs is already installed in the system, it needs to be installed again.

Before installing zfs, you need to install the kernel header file first. For the method of installing the kernel header file, please refer to the instructions in the section on the method of installing the kernel header file.

In Ubuntu20.04, Ubuntu22.04 and Debian11 systems, zfs cannot be installed directly through apt, because the default apt source zfs version is lower than 2.1.6, and there is a problem of incompatibility with rk Linux5.10 kernel. This problem is fixed in zfs version 2.1.6 and later.

To solve this problem, we provide a zfs deb package that can be installed normally, which can be downloaded from the official tool of the development board. Open the official tool, and enter the zfs-related deb package folders used by Ubuntu and Debian systems. You can see three types of deb packages: Ubuntu20.04, Ubuntu22.04 and Debian11. Please download the required version.

Pi3b-img368.png

After downloading the zfs deb packages of the corresponding version, please upload them to the Linux system of the development board. For the upload method, please refer to the description in the section of the method of uploading files to the Linux system of the development board.

After the upload is complete, use the cd command in the command line of the development board Linux system to enter the directory of the deb package, and then use the following command to install the deb package of zfs.

orangepi@orangepi:~$ sudo apt install ./*.deb

After the installation is complete, use the following command to see the zfs-related kernel modules:

orangepi@orangepi:~$ ls /lib/modules/5.10.160-rockchip-rk356x/updates/dkms/

icp.ko spl.ko zavl.ko zcommon.ko zfs.ko zlua.ko znvpair.ko zunicode.ko zzstd.ko

Then restart the Linux system to see that the zfs kernel module will be automatically loaded:

orangepi@orangepi:~$ lsmod | grep "zfs"

zfs                     2801664     0

zunicode             327680     1   zfs

zzstd                  471040     1   zfs

zlua                    139264     1   zfs

zcommon             69632     1   zfs

znvpair                 61440     2   zfs,zcommon

zavl                      16384     1   zfs

icp                     221184     1   zfs

spl                       77824     6   zfs,icp,zzstd,znvpair,zcommon,zavl

In Debian12, the default version of zfs is 2.1.11, so we can install zfs directly through the following command. Again, please make sure that the system has installed the deb package of the kernel header file before installation.

orangepi@orangepi:~$ sudo apt install -y zfsutils-linux zfs-dkms

Methods of creating ZFS pools

ZFS is based on storage pools, we can add multiple physical storage devices to the pool, and then allocate storage space from this pool.

The following content is demonstrated based on the development board connected to an NVMe SSD and a USB flash drive.

  1. First, we can use the lsblk command to view all storage devices on the development board. The current development board is connected to an NVMe SSD and a U disk. The output is as follows:
Pi3b-img369.png
  1. Then enter the following command to create a ZFS pool, including two storage devices, NVMe SSD and U disk
  2. orangepi@orangepi:~$ sudo zpool create -f pool1 /dev/nvme0n1 /dev/sda

  1. Then use the zpool list command to see that the system has created a ZFS pool named pool1, and the size of the ZFS pool pool1 is the size of the NVME SSD plus the size of the U disk
  2. Pi3b-img370.png

  1. Then execute df -h to see that pool1 is mounted to the /pool1 directory
  2. orangepi@orangepi:~$ df -h

    Filesystem                 Size     Used Avail Use% Mounted on

    tmpfs                    1.6G     18M 1.6G 2% /run

    /dev/mmcblk0p2     29G     6.0G 22G 22% /

    tmpfs                    7.7G     46M 7.7G 1% /dev/shm

    tmpfs                    5.0M     4.0K 5.0M 1% /run/lock

    tmpfs                    7.7G     944K 7.7G 1% /tmp

    /dev/mmcblk0p1     1022M     115M 908M 12% /boot

    /dev/zram1                 188M     4.5M 169M 3% /var/log

    tmpfs                    1.6G     80K 1.6G 1% /run/user/1000

    pool1                    489G     9.3M 489G 1% /pool1

  1. Use the following command to see that the file system type of pool1 is zfs
  2. orangepi@orangepi:~$ mount | grep pool1

    pool1 on /pool1 type zfs (rw,xattr,noacl)

  1. Then we can test copying a file to the ZFS pool
  2. orangepi@orangepi:~$ sudo cp -v /usr/local/test.mp4 /pool1/

    '/usr/local/test.mp4' -> '/pool1/test.mp4'

Test the data deduplication function of ZFS

  1. The data deduplication function of ZFS is disabled by default, we need to execute the following command to enable it

orangepi@orangepi:~$ sudo zfs set dedup=on pool1

  1. Then do a simple test, first enter pool1, and then execute the following command to generate a random file with a size of 1G
  2. orangepi@orangepi:~$ cd /pool1/

    root@orangepi:/pool1$ sudo dd if=/dev/urandom of=test.1g bs=1M count=1024

    1024+0 records in

    1024+0 records out

    1073741824 bytes (1.1 GB, 1.0 GiB) copied, 5.04367 s, 213 MB/s

  1. Then use the following command to copy 1000 random files of size 1G
  2. root@orangepi:/pool1$ for ((i=0; i<1000; i++)); do sudo cp test.1g $i.test.1g; done

  1. Then use du -lh to see that there are currently 1002G of data in the pool, but in fact the size of the ZFS pool is only 504GB (the total capacity of SSD+U disk), which cannot hold such a large amount of data
  2. root@orangepi:/pool1$ du -lh

    1002G

  1. Then use the zpool list command to see that only 1.01G is actually occupied, because these 1001 files are all duplicates, indicating that the data deduplication function is effective.
  2. Pi3b-img371.png

Test the data compression function of ZFS

  1. Because the stored data is different, the disk space saved by compression will also be different, so we choose to compress relatively large plain text files for compression testing, and execute the following commands to pack the /var/log/ and /etc/ directories into a tarball

orangepi@orangepi:~$ cd /pool1/

root@orangepi:/pool1$ sudo tar -cf text.tar /var/log/ /etc/

  1. Then the file size that can be seen through the ls -lh command and the space occupied in the ZFS pool are both 27M
  2. Pi3b-img372.png

  1. Then we enable compression in the ZFS pool pool1
  2. root@orangepi:/pool1$ sudo zfs set compression=lz4 pool1

  1. Then execute the following command again to package the /var/log/ and /etc/ directories into a tar package
  2. root@orangepi:/pool1$ sudo tar -cf text.tar /var/log/ /etc/

  1. At this time, you can see that the size of the text.tar file is still 27M, but it only occupies 9.47M in the ZFS pool, indicating that the file is compressed
  2. Pi3b-img373.png

How to shut down and restart the development board

  1. During the running of the Linux system, if the Type-C power supply is directly unplugged, some data may be lost or damaged in the file system, so please use the poweroff command to shut down the Linux system of the development board before powering off. Then unplug the power again.

orangepi@orangepi:~$ sudo poweroff

  1. In addition, the development board is equipped with a switch button, and you can also short press the switch button on the development board to shut down.
  2. Pi3b-img374.png

    Note that the Linux desktop version system will pop up a confirmation box as shown in the figure below after pressing the switch button, and the system will shut down only after clicking the Shut Down option.

    Pi3b-img375.png
  1. Short press the switch button on the development board after shutting down to start up.
  2. Pi3b-img374.png

  1. The command to restart the Linux system is
  2. orangepi@orangepi:~$ sudo reboot

Linux SDK——orangepi-build instructions

Compilation system requirements

We can cross-compile the Linux image of the development board on the x64 computer, or compile the Linux image of the development board on the Ubuntu22.04 system of the development board, please choose one according to your preference.


If you use orangepi-build to compile the Linux image in the Ubuntu22.04 system of the development board, please do a good job of cooling (especially when the SSD starts). If the heat dissipation is not done well, it is prone to the error of file system runaway.

Compile with the Ubuntu22.04 system of the development board

  1. The Linux SDK, namely orangepi-build, supports running on the Ubuntu 22.04 of the development board (other systems have not been tested), so before downloading orangepi-build, please first ensure that the Ubuntu version installed on the development board is Ubuntu 22.04. The command to check the Ubuntu version installed on the development board is as follows. If the Release field does not display 22.04, it means that the current Ubuntu version does not meet the requirements. Please replace the system before performing the following operations.

orangepi@orangepi:~$ lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 22.04.1 LTS

Release: 22.04

Codename: jammy

  1. Since the source codes such as the kernel and U-boot are stored on GitHub, it is very important to ensure that the development board can download codes from GitHub normally when compiling the image.

Compile with x64 Ubuntu22.04 computer

  1. The Linux SDK, orangepi-build, supports running on computers with Ubuntu 22.04 installed, so before downloading orangepi-build, please make sure that the Ubuntu version installed on your computer is Ubuntu 22.04. The command to check the Ubuntu version installed on the computer is as follows. If the Release field does not display 22.04, it means that the current Ubuntu version does not meet the requirements. Please replace the system before performing the following operations.

test@test:~$ lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 22.04 LTS

Release: 22.04

Codename: jammy

  1. If the computer is installed with Windows system and there is no computer with Ubuntu 22.04 installed, you can consider using VirtualBox or VMware to install an Ubuntu 22.04 virtual machine in the Windows system. But please be careful not to compile orangepi-build on the WSL virtual machine, because orangepi-build has not been tested in the WSL virtual machine, so it cannot be guaranteed that orangepi-build can be used normally in WSL.

  2. The download address of the installation image of Ubuntu 22.04 amd64 version is:

  3. https://mirrors.tuna.tsinghua.edu.cn/ubuntu-releases/22.04/ubuntu-22.04-desktop-amd64.iso

    Or

    https://repo.huaweicloud.com/ubuntu-releases/22.04/ubuntu-22.04.1-desktop-amd64.iso

  1. After installing Ubuntu 22.04 on the computer or virtual machine, please set the software source of Ubuntu 22.04 to Tsinghua source, otherwise it is easy to make mistakes due to network reasons when installing the software later

    1. For the method of replacing Tsinghua source, please refer to the instructions on this web page
    2. https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/

    1. Note that the Ubuntu version needs to be switched to 22.04
    2. Pi3b-img376.png

    1. The content of the /etc/apt/sources.list file that needs to be replaced is
    2. test@test:~$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak

      test@test:~$ sudo vim /etc/apt/sources.list

      # By default, the source image is commented to improve the speed of apt update, you can uncomment it yourself if necessary

      deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse

      # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse

      deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse

      # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-security main restricted universe multiverse


      # Pre-release software source, not recommended to enable

      # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse

      # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse

    1. After the replacement, you need to update the package information and make sure there is no error
    2. test@test:~$ sudo apt update

    1. In addition, since the source codes such as the kernel and U-boot are stored on GitHub, it is very important to ensure that the computer can download codes from GitHub normally when compiling the image.

Get the source code of Linux sdk

Download orangepi-build from github

  1. The Linux sdk actually refers to the code of orangepi-build. orangepi-build is modified based on the armbian build system. Using orangepi-build, multiple versions of Linux images can be compiled. First download the code of orangepi-build, the command is as follows:

test@test:~$ sudo apt-get update

test@test:~$ sudo apt-get install -y git

test@test:~$ git clone https://github.com/orangepi-xunlong/orangepi-build.git -b next

Note that the Orange Pi 3B development board needs to download the source code of the next branch of orangepi-build. The above git clone command needs to specify the branch of the orangepi-build source code as next.

Pi3b-img377.png

Downloading the orangepi-build code through the git clone command does not require entering the user name and password of the github account (the same is true for downloading other codes in this manual), if the Ubuntu PC prompts the user to enter the github account after entering the git clone command The name and password are usually entered incorrectly in the address of the orangepi-build warehouse behind the git clone. Please check the spelling of the command carefully, instead of thinking that we forgot to provide the username and password of the github account.

  1. The u-boot and Linux kernel versions currently used by the development board are as follows
  2. branch u-boot version Linux Kernel version
    legacy u-boot 2017.09 Linux5.10

    The branch mentioned here is not the same thing as the branch of the orangepi-build source code, please do not confuse it. This branch is mainly used to distinguish different kernel source code versions.

    Currently, the Linux5.10 bsp kernel provided by RK is defined as the legacy branch. If the mainline kernel is supported in the future, a current branch will be added.

  1. orangepi-build will contain the following files and folders after downloading

    1. build.sh: Compile the startup script

    2. external: Contains the configuration files needed to compile the image, specific scripts, and the source code of some programs, etc.

    3. LICENSE: GPL 2 license file

    4. README.md: orangepi-build documentation

    5. scripts: General script for compiling Linux images

    6. test@test:~/orangepi-build$ ls

      build.sh      external      LICENSE      README.md      scripts

      If you downloaded the code of orangepi-build from github, after downloading, you may find that orangepi-build does not contain the source code of u-boot and Linux kernel, nor does u-boot and Linux kernel need to use cross-compilation tools Chain, this is normal, because these things are stored in other separate github warehouses or some servers (the addresses will be detailed below). orangepi-build will specify the address of u-boot, Linux kernel and cross-compilation toolchain in the script and configuration file. When running orangepi-build, when it finds that there are no such things locally, it will automatically go to the corresponding place to download them.

Download the cross-compilation toolchain

The cross-compilation toolchain will only be downloaded when the orangepi-build compilation image is used on an x64 computer. Compiling the Linux image of the development board in the Ubuntu22.04 of the development board will not download the cross-compilation toolchain. At this time, orangepi-build/toolchains will be an empty folder.

  1. When orangepi-build runs for the first time, it will automatically download the cross-compilation toolchain and put it in the toolchains folder. Every time after running the build.sh script of orangepi-build, it will check whether the cross-compilation toolchain in toolchains exists , if it does not exist, the download will be restarted, if it exists, it will be used directly, and the download will not be repeated.
Pi3b-img378.png
  1. The image URL of the cross-compilation toolchain in China is the open source software image site of Tsinghua University
  2. https://mirrors.tuna.tsinghua.edu.cn/armbian-releases/_toolchain/

  1. After toolchains is downloaded, it will contain multiple versions of cross-compilation toolchains, and the development board will only use two of them

      3 directories, 6 files

  1. When the orangepi-bulid compilation system compiles the u-boot source code, it will first synchronize the u-boot source code with the u-boot source code of the github server, so if you want to modify the u-boot source code, you first need to turn off the download and update function of the source code (This function needs to be fully compiled once u-boot, otherwise it will prompt that the source code of u-boot cannot be found. If the source code compressed package is downloaded from Google cloud disk, there is no such problem, because the source code of u-boot have been cached), otherwise the changes made will be reverted, the method is as follows:
  2. Set the IGNORE_UPDATES variable in userpatches/config-default.conf to "yes"

    test@test:~/orangepi-build$ vim userpatches/config-default.conf

    IGNORE_UPDATES="yes"

  2. console:/ # setprop service.adb.tcp.port 5555

    console:/ # stop adbd

    console:/ # start adbd

  1. Install adb tool on Ubuntu PC
  2. test@test:~$ sudo apt update

    test@test:~$ sudo apt install -y adb

  1. Then connect network adb on Ubuntu PC
  2. test@test:~$ adb connect 192.168.1.xxx (The IP address needs to be changed to the IP address of the development board)

    * daemon not running; starting now at tcp:5037

    * daemon started successfully

    connected to 192.168.1.xxx:5555
