How to use Win32Diskimager to burn Linux image

1) First prepare a TF card with a capacity of 16GB or more. The transmission speed of the TF card must be class 10 or above. It is recommended to use a TF card of SanDiskand other brands

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

3) Then format the TF card
a. SD Card Formatter can be used to format the TF card. The 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 a TF card is inserted into the computer, the drive letter of the TF card will be displayed in the "Select card" column. If multiple USB storage devices are inserted into the computer, you can select the corresponding drive letter of the TF card through the drop-down box

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

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

4) Download the Linux operating system image file compression package that you want to burn from the Orange Pi data download page, and then use the decompression software to decompress it. Among the decompressed files, the file ending with ".img" is the image file of the operating system. The size is generally more than 2GB

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 interface of Win32Diskimager 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 that 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

Onboard LED Light Test Instructions

1) There are two LED lights on the development board, one is green and the other is red. The location is shown in the figure below:

2) As long as the development board is powered on, the red LED light will always be on, which is controlled by the hardware and cannot be turned off by the software.

3) The green LED light will keep flashing after the kernel is started, which is controlled by software.

4) The method of setting the green light on and off and flashing is as follows

Note that the following operations should be performed under the root user.

a. First enter the setting directory of the green light

root@orangepi:~# cd /sys/class/leds/status_led

b. The command to set the green light to stop flashing is as follows

root@orangepi:/sys/class/leds/status_led# echo none > trigger

c. The command to set the green light to be on is as follows

root@orangepi:/sys/class/leds/status_led# echo 1 > brightness

d. The command to set the green light to flash is as follows

root@orangepi:/sys/class/leds/status_led# echo heartbeat > trigger

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

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 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 monitor, 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: A) 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; B) Check whether the network cable is plugged in tightly, or try another network cable; C) 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); D) If there is no router to replace, you can only connect to an HDMI display or use the debugging serial port to check the IP address. In addition, it should be noted that the development board DHCP automatically assigns an IP address without any settings.

4) The command to test the network connectivity is as follows, the ping command can be interrupted through the shortcut key of Ctrl+C

orangepi@orangepi:~$ ping www.baidu.com -I eth0 PING www.a.shifen.com (14.215.177.38) from 192.168.1.12 eth0: 56(84) bytes of data. 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=1 ttl=56 time=6.74 ms 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=2 ttl=56 time=6.80 ms 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=3 ttl=56 time=6.26 ms 64 bytes from 14.215.177.38 (14.215.177.38): icmp_seq=4 ttl=56 time=7.27 ms ^C --- www.a.shifen.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 6.260/6.770/7.275/0.373 ms

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.

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

orangepi@orangepi:~$ nmcli dev wifi

3) Then use the nmcli command to connect to the scanned WIFI hotspot, where：
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'.

4) You can view the IP address of wifi through the ip addr show wlan0 command

How to use AP6275P PCIe network card

1) First, you need to purchase an AP6275P PCIe network card as shown in the figure below

2) Then insert the AP6275P PCIe network card into the M.2 interface of the development board and fix it

3) Then open the configuration of the AP6275P PCIe network card in the linux system, the steps are as follows：
a. First run orangepi-config, normal users remember to add sudo permission

orangepi@orangepi:~$ sudo orangepi-config

b. Then select System

c. Then select Hardware

d. Then use the arrow keys on the keyboard to navigate to wifi-ap6275p, and then use the space to select

e. Then select <Save> to save

f. Then select <Back>

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

The above settings will eventually add the configuration of overlays=wifi-ap6275p 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 open /boot/orangepiEnv.txt, and then add the configuration of overlays=wifi-ap6275p.

4) If everything is normal after restarting the system, use the following command to see the device nodes of WIFI and Bluetooth
a. The command to view the WIFI device node is as follows：

orangepi@orangepi:~$ ip addr show wlan0 3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state DORMANT group default qlen 1000 link/ether 70:f7:54:b8:b3:17 brd ff:ff:ff:ff:ff:ff

b. The command to view the Bluetooth device node is as follows：

orangepi@orangepi:~$ hciconfig -a hci0: Type: Primary Bus: UART BD Address: 82:CC:AE:62:CE:3E ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:958 acl:0 sco:0 events:73 errors:0 TX bytes:5544 acl:0 sco:0 commands:73 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'orangepi5' Class: 0x1c0000 Service Classes: Rendering, Capturing, Object Transfer Device Class: Miscellaneous, HCI Version: 5.1 (0xa) Revision: 0x3f9 LMP Version: 5.1 (0xa) Subversion: 0x1111 Manufacturer: Broadcom Corporation (15)

6) For the test method of Bluetooth, please refer to the section on Bluetooth usage, so I won’t go into details here

AP6275P PCIe NIC creates WIFI hotspot via create_ap

create_ap is a script that helps quickly create WIFI hotspots on Linux, and supports bridge and NAT modes. It can automatically combine hostapd, dnsmasq and iptables to complete the setting of WIFI hotspots, avoiding complex configuration for users. The github address is as follows： https://github.com/oblique/create_ap

If you using the latest image, the create_ap script has been pre-installed, and you can create a WIFI hotspot through the create_ap command. The basic command format of create_ap is as follows: create_ap [options] <wifi-interface> [<interface-with-internet>] [<access-point-name> [<passphrase>]]

1.create_ap method to create WIFI hotspot in NAT mode

1) Enter the following command to create a WIFI hotspot named orangepi and password orangepi in NAT mode

orangepi@orangepi5:~$ sudo create_ap -m nat wlan0 eth0 orangepi orangepi

2) If the following information is output, it means that the WIFI hotspot is created successfully

orangepi@orangepi5:~$ sudo create_ap -m nat wlan0 eth0 orangepi orangepi Config dir: /tmp/create_ap.wlan0.conf.fPItFUJ2 PID: 3831 Network Manager found, set ap0 as unmanaged device... DONE Creating a virtual WiFi interface... ap0 created. Sharing Internet using method: nat hostapd command-line interface: hostapd_cli -p /tmp/create_ap.wlan0.conf.fPItFUJ2/hostapd_ctrl ap0: interface state UNINITIALIZED->ENABLED

3) Take out the mobile phone at this time, in the searched WIFI list, you can find the WIFI hotspot named orangepi created by the development board, and then click orangepi to connect to the hotspot, the password is the orangepi set above

4) After the connection is successful, the display is as shown in the figure below

5) In NAT mode, the wireless device connected to the hotspot of the development board requests an IP address from the DHCP service of the development board, so there will be two different network segments, for example, the IP of the development board is 192.168.1.X

orangepi@orangepi5:~$ ifconfig eth0 eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.150 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::938f:8776:5783:afa2 prefixlen 64 scopeid 0x20<link> ether 4a:a0:c8:25:42:82 txqueuelen 1000 (Ethernet) RX packets 25370 bytes 2709590 (2.7 MB) RX errors 0 dropped 50 overruns 0 frame 0 TX packets 3798 bytes 1519493 (1.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 83

By default, the DHCP service of the development board will assign an IP address of 192.168.12.0/24 to the device connected to the hotspot. At this time, click on the connected WIFI hotspot orangepi, and then you can see that the IP address of the mobile phone is 192.168.12.X

6) If you want to specify a different network segment for the connected device, you can specify it through the -g parameter, such as specifying the network segment of the access point AP through the -g parameter as 192.168.2.1

orangepi@orangepi5:~$ sudo create_ap -m nat wlan0 eth0 orangepi orangepi -g 192.168.2.1

At this time, after connecting to the hotspot through the mobile phone, click the connected WIFI hotspot orangepi, and then you can see that the IP address of the mobile phone is 192.168.2.X

7) If the --freq-band parameter is not specified, the hotspot created by default is in the 2.4G frequency band. If you want to create a hotspot in the 5G frequency band, you can specify it through the --freq-band 5 parameter. The specific command is as follows

orangepi@orangepi:~$ sudo create_ap -m nat wlan0 eth0 orangepi orangepi --freq-band 5

8) If you need to hide the SSID, you can specify the --hidden parameter, the specific command is as follows

orangepi@orangepi:~$ sudo create_ap -m nat wlan0 eth0 orangepi orangepi --hidden

At this time, the mobile phone cannot search for the WIFI hotspot. You need to manually specify the name of the WIFI hotspot and enter the password to connect to the WIFI hotspot

2.create_ap method to create WIFI hotspot in bridge mode

1) Enter the following command to create a WIFI hotspot named orangepi and password orangepi in bridge mode

orangepi@orangepi:~$ sudo create_ap -m bridge wlan0 eth0 orangepi orangepi
