5 Work with FriendlyWrt

5.1 Introduction to FriendlyWrt

FriendlyWrt is a customized system made by FriendlyElec based on an OpenWrt distribution. It is open source and well suitable for developing IoT applications, NAS applications, smart home gateways etc.

5.2 First boot

For the first boot, the system needs to do the following initialization work:
1)Extended root file system
2)Initial setup(will execute /root/setup.sh)
So you need to wait for a while (about 2~3 minutes) to boot up for the first time, and then set FriendlyWrt, you can enter the ttyd terminal on the openwrt webpage, when the prompt is displayed as root@FriendlyWrt, it means the system has been initialized.

root@FriendlyWrt

5.3 Account & Password

The default password is password (empty password in some versions). Please set or change a safer password for web login and ssh login. It is recommended to complete this setting before connecting NanoPi-R2S to the Internet.

5.4 Network Connection

Use a network cable to connect NanoPi-R2S's WAN to a master router and the board will get an IP address via DHCP. Login into the router and check NanoPi-R2S's IP address.

5.5 Login FriendlyWrt

Connect the PC to the LAN port of NanoPi-R2S. If your PC without a built-in ethernet port, connect the LAN port of the wireless AP to the LAN port of NanoPi-R2S, and then connect your PC to the wireless AP via WiFi , Enter the following URL on your PC's browser to access the admin page:

The above is the LAN port address of NanoPi-R2S. The IP address of the WAN port will be dynamically obtained from your main router through DHCP.

5.6 Recommended security settings

The following settings are highly recommended to complete before connecting NanoPi-R2S to the Internet。

  • Set a secure password
  • Only allow access to ssh from lan, change the port
  • Only allow local devices to access luci

Edit /etc/config/uhttpd,Change the original 0.0.0.0 and [::] addresses to the local lan address, for example:

	# HTTP listen addresses, multiple allowed
	list listen_http	192.168.2.1:80
	list listen_http	[fd00:ab:cd::1]:80
 
	# HTTPS listen addresses, multiple allowed
	list listen_https	192.168.2.1:443
	list listen_https	[fd00:ab:cd::1]:443

Restart the service:

/etc/init.d/uhttpd restart

5.7 Safe shutdown operation

Enter the ttyd terminal, enter the poweroff command and hit enter, wait until the led light is off, and then unplug the power supply.

5.8 Install Software Packages

5.8.1 Update Package List

Before install software packages update the package list:

$ opkg update

5.8.2 List Available Packages

$ opkg list

5.8.3 List Installed Packages

$ opkg list-installed

5.8.4 Install Packages

$ opkg install <package names>

5.8.5 Remove Packages

$ opkg remove <package names>

5.9 Disable IPv6

sed -i -e "s/DISABLE_IPV6=0/DISABLE_IPV6=1/g" /root/setup.sh
rm -f /etc/board.json /etc/config/system /etc/config/network /etc/config/wireless /etc/firstboot_*
reboot

5.10 Some common issues of FriendlyWrt

  • Unable to dial up
    • Go to "Network" -> "Firewall" and set "Inbound Data", "Outbound Data" and "Forwarding" in "WAN Zone" to "Accept";
    • If you still cannot access the Internet, you can try to turn off IPV6;
  • Unable to power on
    • Try to replace the power adapter and cable. It is recommended to use a power supply with specifications above 5V/2A;
    • Note that some fast chargers with Type-C interface will have a delay, it may take a few seconds to start providing power;
  • When doing secondary routing, the computer cannot connect to the Internet
    • If your main network is IPv4, and NanoPi-R2S works in IPv6, the computer may not be able to connect to the Internet. It is recommended to turn off IPv6 (the method is described later in this WiKi), or switch the main route to IPv6;
  • If you have questions or have better suggestions, please send an email to techsupport@friendlyarm.com;

5.11 Let FriendlyWrt regenerate network settings

This method will trigger FriendlyWrt to re-identify the hardware model and generate the network configuration under /etc/config, which is similar but not completely equivalent to restoring factory settings:

rm -f /etc/board.json /etc/config/system /etc/config/network /etc/config/wireless /etc/firstboot_*
reboot

The /root/setup.sh initialization script will be executed again at the next boot, so you can debug the /root/setup.sh script through this method.

5.12 Use USB2LCD to view IP and temperature

Plug the USB2LCD module to the USB interface ofNanoPi-R2S and power on, the IP address and CPU temperature will be displayed on the LCD:

mv openwrt-sdk-19.07.5-rockchip-rk3328_gcc-7.5.0_musl.Linux-x86_64 sdk
cd sdk
./scripts/feeds update -a
./scripts/feeds install -a

5.16.3 Compile the package

download the source code of the example (a total of 3 examples are example1, example2, example3), and copy to the package directory:

git clone https://github.com/mwarning/openwrt-examples.git
cp -rf openwrt-examples/example* package/
rm -rf openwrt-examples/

Then enter the configuration menu through the following command:

make menuconfig

In the menu, select the following packages we want to compile (actually selected by default):

"Utilities" => "example1"
"Utilities" => "example3"
"Network" => "VPN" => "example2"

execute the following commands to compile the three software packages:

make package/example1/compile V=99
make package/example2/compile V=99
make package/example3/compile V=99

After the compilation is successful, you can find the ipk file in the bin directory, as shown below:

$ find ./bin -name example*.ipk
./bin/packages/aarch64_cortex-a53/base/example2_0.1-1_aarch64_cortex-a53.ipk
./bin/packages/aarch64_cortex-a53/base/example3_0.1-1_aarch64_cortex-a53.ipk

7 Work with FriendlyCore

7.1 FriendlyCore User Account

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

7.2 Update Software Packages

$ sudo apt-get update

7.3 Setup Network Configurations

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

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

vi /etc/systemd/resolved.conf

例如设置为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

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.
