  • How to setup the Compiling Environment on Ubuntu bionic
    

4.2 TF Cards We Tested

Refer to： TFCardsWeTested

4.3 PD Power Adapters We Tested

Refer to： PD Power Adapters We Tested

4.4 Configure parameters for serial port

Use the following serial parameters:

4.5 Install OS

4.5.1 Flash to TF

Visit download linkto download image files (in the "01_Official images/01_SD card images" directory) and utilities (in the "05_Tools" directory)：

The detailed steps are as follows:

• Get an 8G SDHC card and backup its data if necessary;
• Download and extract the xxx.img.gz and win32diskimager;
• 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. Under Linux run "dd" to flash the rkXXXX-sd-OSNAME-YYYYMMDD.img file to your SD card;
• Take out the SD and insert it to NanoPi-R6S's microSD card slot;
• Power on NanoPi-R6S and it will be booted from your TF card;

4.5.2 Install OS to eMMC

4.5.2.1 Option 1: 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.

4.5.2.2 Option 2: 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:

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.

4.5.2.2.1 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-R6S’s microSD card slot.
• Turn on NanoPi-R6S, 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-R6S, NanoPi-R6S will automatically reboot and boot from eMMC.

4.5.2.2.2 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 an .img or .gz file to the TF card.
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

Anyone of the files that contain “-sd-” will work. for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz
4) Eject the TF card, insert the TF card to NanoPi-R6S, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status.

4.5.2.3 Option 3: Install OS via USB

4.5.2.3.1 Step 1: Install USB Driver and Tools/Utilities

Download a driver file DriverAssitant_v5.1.1.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.

4.5.2.3.2 Step 2: Connect NanoPi-R6S to PC and Enter Installation Mode

1) Disconnect the connected USB cable and the power cord from NanoPi-R6S, eject the TF card;
2) Press and hold the “Mask” key, power on the board. After the status LED has been on for at least 3 seconds, release the Mask key.
3) Use a USB A-to-A cable, connect NanoPi-R6S to a PC as follows. Note: please pay attention to the USB port the USB cable is connected to in the screenshot.

4.5.2.3.3 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.

4.6 The Boot order between eMMC and SD card

By default, the system will be booted from the TF card first, but this is not the case under all conditions. This section will explain all situations in detail;

Refer to rockchip official document [1], there are two types of loader program:
1) U-Boot TPL/SPL (i.e. upsream U-Boot, also called mainline U-Boot)
2) Rockchip MiniLoader

Things to note:
1) FriendlyELEC's image uses Rockchip MiniLoader
2) The third-party image usually uses U-Boot TPL/SPL

The following situations will always start from eMMC:
If the system in the eMMC, or the system in the TF card uses the first Loader type U-Boot TPL/SPL, it will always boot from the eMMC;
If you want to boot from the TF card, there are the following methods:
Method 1: Clear the Loader on the eMMC, the clearing method is as follows, after starting from the eMMC, enter the following command on the command line to clear the Loader on the eMMC:

dd if=/dev/zero of=/dev/mmcblk2 bs=8M count=1

Method 2: Insert the TF card, Press Maskrom Key (or short-circuit the Maskrom contacts) and then power on (need to keep the short-circuit for about 3 seconds), it will start from the TF card

The summary is as follows:

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 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-R6S to the Internet.

5.4 Login FriendlyWrt

Connect the PC to the LAN port of NanoPi-R6S. If your PC without a built-in ethernet port, connect the LAN port of the wireless AP to the LAN port of NanoPi-R6S, 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:

• http://friendlywrt/
• http://192.168.2.1/

5.13 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;
• Dial-up successful, but no outgoing traffic
  • Go to "Services" -> "Terminal" and type "fw4 reload" to try to reload the firewall settings again;
• 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-R6S 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;

5.14 Use USB2LCD to view IP and temperature

Plug the USB2LCD module to the USB interface ofNanoPi-R6S and power on, the IP address and CPU temperature will be displayed on the LCD:

5.15 How to use USB WiFi

5.15.1 Check USB WiFi Device with Command Line Utility

(1) Click on "services>ttyd" to start the command line utility

(2) Make sure no USB devices are connected to your board and run the following command to check if any USB devices are connected or not

lsusb

(3) Connect a USB WiFi device to the board and run the command again

lsusb

You will see a new device is detected. In our test the device's ID was 0BDA:C811

(4) Type your device's ID (in our case it was "0BDA:C811" or "VID_0BDA&PID_C811") in a search engine and you may find a device that matches the ID. In our case the device we got was Realtek 8811CU.

5.15.2 Configure a USB WiFi Device as AP

(1) Connect a USB WiFi device to the NanoPi-R6S. We recommend you to use the following devices:

Note: devices that match these VID&PIDs would most likely work.
(2) Click on "System>Reboot" and reboot your NanoPi-R6S

(3) Click on "Network>Wireless" to enter the WiFi configuration page

(4) Click on "Edit" to edit the configuration

(5) On the "Interface Configuration" page you can set the WiFi mode and SSID, and then go to "Wireless Security" to change the password. By default the password is "password". After you make your changes click on "Save" to save

(6) After you change the settings you can use a smartphone or PC to search for WiFi

5.15.3 Common USB WiFi issues

1) It is recommended to plug in the usb wifi in the off state, then power it on, FriendlyWrt will automatically generate the configuration file /etc/config/wireless, if not, see if there is wlan0 by ifconfig -a, if there is no wlan0, usually there is no driver.
2) If ifconfig -a sees wlan0, but the hotspot is not working properly, try changing the channel and country code, an inappropriate country code can also cause the WiFi to not work.
3) Some USB WiFis (e.g. MTK MT7662) work in CD-ROM mode by default and need to be switched by usb_modeswitch, you can try to add usb_modeswitch configuration to the following directory: /etc/usb_modeswitch.d.

5.15.4 Change the default WiFi hotspot configuration

FriendlyWrt sets the country, hotspot name and other parameters for USB WiFi by default, with the aim of being as plug-and-play as possible, but this does not guarantee that all modules will be compatible with this setting, you can change these behaviors by modifying the following file：

/lib/wifi/mac80211.sh

5.16 Work with Docker Applications

5.16.1 Work with Docker: Install JellyFin

mkdir -p /jellyfin/config

5.18.1 Install the compilation environment

Download and run the following script on 64-bit Ubuntu (version 18.04+): How to setup the Compiling Environment on Ubuntu bionic

5.18.2 Download and decompress sdk from the network disk

The sdk is located in the toolchain directory of the network disk:

tar xvf openwrt-sdk-*-rockchip-armv8_gcc-11.2.0_musl.Linux-x86_64.tar.xz
# If the path is too long, it will cause some package compilation errors, so change the directory name here
mv openwrt-sdk-*-rockchip-armv8_gcc-11.2.0_musl.Linux-x86_64 sdk
cd sdk
./scripts/feeds update -a
./scripts/feeds install -a

5.18.3 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_generic/base/example3_1.0.0-220420.38257_aarch64_generic.ipk
./bin/packages/aarch64_generic/base/example1_1.0.0-220420.38257_aarch64_generic.ipk
./bin/packages/aarch64_generic/base/example2_1.0.0-220420.38257_aarch64_generic.ipk

5.18.4 Install the ipk to NanoPi

You can use the scp command to upload the ipk file to NanoPi:

cd ./bin/packages/aarch64_generic/base/
scp example*.ipk root@192.168.2.1:/root/

Then use the opkg command to install them:

cd /root/
opkg install example3_1.0.0-220420.38257_aarch64_generic.ipk
opkg install example1_1.0.0-220420.38257_aarch64_generic.ipk

5.19 Build FriendlyWrt using GitHub Actions

Please refre this link: https://github.com/friendlyarm/Actions-FriendlyWrt

6 Work with FriendlyCore

6.1 FriendlyCore User Account

• Non-root User:

   User Name: pi
   Password: pi

• Root:

   User Name: root
   Password: fa

6.2 Update Software Packages

$ sudo apt-get update

6.3 Setup Network Configurations

6.3.1 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

The other two ethernet ports are set up with static IP addresses, as follows:
eth1: 192.168.2.1
eth2: 192.168.3.1 (Note: if there are three network ports)

6.3.2 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

6.3.3 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.

6.4 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

6.5 Install the kernel-header package

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

6.6 Config status LEDs

First determine whether the system already exists the leds initialization service:

sudo systemctl status leds

If the leds service already exists, change the default behavior of the LEDs by editing the following file:

/etc/init.d/leds.sh

Since there is no leds service in the early firmware, you need to refer to the following guide to manually configure the LEDs. First, set the following kernel modules to be automatically loaded at boot:

modprobe ledtrig-netdev
echo ledtrig-netdev > /etc/modules-load.d/ledtrig-netdev.conf

Put the following into the autorun script to associate the status leds with the ethernet interface, and you can configure it to behave in other ways by referring to these content:

echo netdev > /sys/class/leds/wan_led/trigger
echo eth0 > /sys/class/leds/wan_led/device_name
echo 1 > /sys/class/leds/wan_led/link
 
echo netdev > /sys/class/leds/lan1_led/trigger
echo eth1 > /sys/class/leds/lan1_led/device_name
echo 1 > /sys/class/leds/lan1_led/link
 
echo netdev > /sys/class/leds/lan2_led/trigger
echo eth2 > /sys/class/leds/lan2_led/device_name
echo 1 > /sys/class/leds/lan2_led/link

9 How to Compile

9.1 Build Openwrt/Friendlywrt

9.1.1 Download Code

Two versions are available, please choose as required:

9.1.1.1 FriendlyWrt 22.03.2

mkdir friendlywrt22-rk3588
cd friendlywrt22-rk3588
git clone https://github.com/friendlyarm/repo --depth 1 tools
tools/repo init -u https://github.com/friendlyarm/friendlywrt_manifests -b master-v22.03 \
        -m rk3588.xml --repo-url=https://github.com/friendlyarm/repo  --no-clone-bundle
tools/repo sync -c  --no-clone-bundle

9.1.1.2 FriendlyWrt 21.02.5

mkdir friendlywrt21-rk3588
cd friendlywrt21-rk3588
git clone https://github.com/friendlyarm/repo --depth 1 tools
tools/repo init -u https://github.com/friendlyarm/friendlywrt_manifests -b master-v21.02 \
        -m rk3588.xml --repo-url=https://github.com/friendlyarm/repo  --no-clone-bundle
tools/repo sync -c  --no-clone-bundle

9.1.2 First compilation step

./build.sh rk3588.mk  # or rk3588-docker.mk

All the components (including u-boot, kernel, and friendlywrt) are compiled and the sd card image will be generated, then execute the following command to generate the image file for installing the system into the emmc:

./build.sh emmc-img

After making changes to the project, the sd card image needs to be repackaged by running the following command:

./build.sh sd-img

9.1.3 Secondary compilation steps

cd friendlywrt
make menuconfig
rm -rf ./tmp
make -j${nproc}
cd ../
./build.sh sd-img
./build.sh emmc-img

9.2 Build u-boot only

./build.sh uboot

9.3 Build kernel only

./build.sh kernel

9.4 Build friendlywrt only

./build.sh friendlywrt

Or go to the friendlywrt directory and follow the standard openwrt commands. If you get an error with the above command, try using the following command to compile in a single thread:

cd friendlywrt
make -j1 V=s

10 Backup rootfs and create custom SD image (to burn your application into other boards)

10.1 Backup rootfs

Run the following commands on your target board. These commands will back up the entire root partition:

sudo passwd root
su root
cd /
tar --warning=no-file-changed -cvpzf /rootfs.tar.gz \
    --exclude=/rootfs.tar.gz --exclude=/var/lib/docker/runtimes \
    --exclude=/etc/firstuser --exclude=/etc/friendlyelec-release \
    --exclude=/usr/local/first_boot_flag --one-file-system /

Note: if there is a mounted directory on the system, an error message will appear at the end, which can be ignored.

10.2 Making a bootable SD card from a root filesystem

Only support RK3328/RK3399/RK3568/RK3566/RK3588
