  • Run the win32diskimager utility under Windows as administrator. On the utility's main window select your SD card's drive, the wanted image file and click on "write" to start flashing the SD card.
  • Take out the SD and insert it to NanoPi-Zero2's microSD card slot;
  • Power on NanoPi-Zero2 and it will be booted from your TF card, some models may require pressing the Power button to start;

4.4.3 Install OS to eMMC

4.4.3.1 Option 1: Install OS via TF Card

This method firstly boots a mini Linux from a TF card and then automatically runs an EFlasher utility to install the OS to eMMC. You can connect your system to an HDMI monitor and watch its progress.
This is optional. You can watch its progress by observing its LEDs as well:

Slow Flashing

By default, flashing starts automatically upon power-up, so be sure to back up the data in eMMC. If you don't want it to start automatically, you can use image file with a filename containing the words 'multiple-os' and manually select the OS you want to flash on the interface.

4.4.3.1.1 Flash Official OS to eMMC

Follow the steps below:

  • Get an SDHC card with a minimum capacity of 8G
  • Visit download linkto download image files (in the "01_Official images/02_SD-to-eMMC images" directory) and win32diskimager tool (in the "05_Tools" directory);
  • Extract the .gz format compressed file to get the .img format image file;
  • Run the win32diskimager utility under Windows as administrator. On the utility's main window select your SD card's drive, the wanted image file and click on "write" to start flashing the SD card.
  • Eject your SD card and insert it to NanoPi-Zero2’s microSD card slot.
  • Turn on NanoPi-Zero2, it will boot from the SD card and automatically run EFlasher to install the OS to the board’s eMMC.
  • After flashing is complete, eject the SD card from NanoPi-Zero2, NanoPi-Zero2 will automatically reboot and boot from eMMC.
4.4.3.1.2 Flash third party OS (Image file) to eMMC
  • Auto Install (Default Behavior)

1) Download an “eflasher” firmware from network drive(in the "01_Official images/02_SD-to-eMMC images" directory), extract it and install it to a TF card ;
2) Eject and insert the TF card to your PC, after a “FriendlyARM” device shows up(Under Linux, it is a “FriendlyARM” directory), copy the image file ending with .raw or .gz into the directory (Note: if your file is in .img format, please rename it to .raw format).
3) Open the eflasher.conf file on the TF card, set “autoStart=” to the name of your image file, such as:

autoStart=openwrt-rockchip-armv8_nanopi-ext4-sysupgrade.img.gz

In addition to third-party image, official image files which with the '-sd-' word in the filename are also supported, for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz
4) Eject the TF card, insert the TF card to NanoPi-Zero2, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status.

4.4.3.2 Option 2: Install OS on Web Page

Get a TF card which has been installed with FriendlyWrt, log in FriendlyWrt on the web page, click on “System” ->”eMMC Tools”. Click on “Select file” to select your wanted image file, either an official image (filename containing '-sd-') or a third party image. The file should be a “.gz” or “.img” file.
After a file is selected, click on “Upload and Write” to start installing an OS.

After installation is done, eject the SD card, the system will automatically reboot and load the OS from eMMC. After the OS begins to load, if the system LED is flashing and the network LED is on, it means the the OS has loaded successfully. If the OS is FriendlyWrt, you can click on “Go to Homepage” to enter the homepage.
For official OS, you need select the file with the filename containing '-sd-', for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz, the compression file only supports the .gz format. If the file is too large, you can compress it into .gz format before uploading.

4.4.3.3 Option 3: Install OS via USB
4.4.3.3.1 Step 1: Install USB Driver and Tools/Utilities

Download a driver file DriverAssitant_v5.12.zip under the “tools” directory from network drive, extract and install it.
Under the same directory, download a utility RKDevTool_Release_v2.84.zip and extract it.

4.4.3.3.2 Step 2: Connect NanoPi-Zero2 to PC and Enter Installation Mode

Press and hold the “Mask” key, Use a USB cable, connect NanoPi-Zero2 to a PC，After the status LED has been on for at least 3 seconds, release the Mask key;

4.4.3.3.3 Step 3: Install image to eMMC

A firmware in general is packaged in either of the two options: the first is an whole image (ie, update.img) which is often offered by third party developers, the second is that an image is packaged and placed in multiple partition images. FriendlyElec offers an image in the latter option.

  • Option 1: Install whole image (ie, update.img)

On a PC which has the extracted RKDevTool_Release_v2.84 utility, go to the RKDevTool_Release_v2.84 directory, run the RKDevTool.exe file. If everything works, you will see a “Found a new Maskrom device” message on the utility;
Go to “Upgrade Firmware(升级固件)”, click on “Firmware(固件)”, select your wanted image file, and click on “Upgrade(升级)” to install. After installation is done, your board will reboot automatically and load the system from eMMC;

  • Option 2: Install OS that is packaged & placed in multiple partition images

Go to network drive to download your needed package and extract it (in the "01_Official images/03_USB upgrade images). After it is extracted, you will see some utilities and a configuration file under the directory. double click on RKDevTool.exe, you will see a “Found a new Maskrom device” message on the utility. Click on the “Execute”, wait a moment and it will be installed. After installation is done your system will automatically reboot and load the system from eMMC.

5 Work with FriendlyCore

5.1 FriendlyCore User Account

  • Non-root User:
   User Name: pi
   Password: pi
  • Root:
   User Name: root
   Password: fa

5.2 Update Software Packages

$ sudo apt-get update

5.3 Setup Network Configurations

5.3.1 Set static IP address

By default "eth0" is assigned an IP address obtained via dhcp. If you want to change the setting you need to change the following file: 

vi /etc/network/interfaces.d/eth0

For example if you want to assign a static IP to it you can run the following commands: 

auto eth0
iface eth0 inet static
    address 192.168.1.231
    netmask 255.255.255.0
    gateway 192.168.1.1

5.3.2 Set a DNS

You also need to modify the following file to add the DNS configuration: 

vi /etc/systemd/resolved.conf

For example, set to 192.168.1.1: 

[Resolve]
DNS=192.168.1.1

Restart the systemd-resolved service with the following command: 

sudo systemctl restart systemd-resolved.service
sudo systemctl enable systemd-resolved.service

5.3.3 Set up to use another network interface

To change the setting of "eth1" you can add a new file similar to eth0's configuration file under the /etc/network/interfaces.d/ directory.

5.4 Setup Wi-Fi

First, use the following command to check if Network-Manager is installed on your system: 

which nmcli

If you have installed it, refer to this link to connect to WiFi: Use NetworkManager to configure network settings, If you do not have Network-Manager installed on your system, please refer to the following method to configure WiFi,
By default the WiFi device is "wlan0". You need to create a configuration file under "/etc/network/interfaces.d/" for WiFi: 

vi /etc/network/interfaces.d/wlan0

Here is a sample wlan0 file: 

auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid YourWiFiESSID
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk YourWiFiPassword

Please replace "YourWiFiESSID" and "YourWiFiPassword" with your WiFiESSID and password. After save and close the file you can connect to your WiFi source by running the following command: 

sudo systemctl daemon-reload
sudo systemctl restart networking

After you power on your board it will automatically connect to your WiFi source.
Please note that if you use one TF card to boot multiple boards the WiFi device name will likely be named to "wlan1", "wlan2" and etc. You can reset it to "wlan0" by deleting the contents of the following file and reboot your board: /etc/udev/rules.d/70-persistent-net.rules

5.5 Install the kernel-header package

sudo dpkg -i /opt/linux-headers-*.deb
