- Note:
- VDD_5V: Supply voltage, range:4.7 ~ 5.6V. We recommend a 5V/1.2A(MAX) power. You can lower the clock to decrease the power consumption. When the clock is lowered by 200MHz the power consumption roughly decreases 0.5W .
- BOOT_CS: Boot chip selection. When it is not connected or pulled up the board boots from eMMC otherwise it boots from SD card
- NRESETIN: Reset input. Activated when it is low. A reset signal is input to CPU from this pin
- NRESETOUT: Reset output. Activated when it is low. CPU's reset signal outputs to this pin.
- RTC_BATT: RTC's input, direct connection to a 3V power source. If the CPU board is powered on the RTC seat is powered by 3.3V external power otherwise when the CPU board is not powered on it is powered by the RTC battery.
- ADC1~7: CPU internal ADC, 12-bit, 7 channels 1~7, range:0 ~ 1.8V
- 10/100M Ethernet mode: LAN_MDI1_N/P=RX-/+, LAN_MDI0_N/P=TX-/+, four pins connected to RJ45
- 10/100/1000M Ethernet mode: LAN_MDI0_N/P~LAN_MDI3N/P, all eight pins connected to RJ45

5 Notes in Hardware Design
5.1 EEPROM
- The Smart4418 CPU board has an EEPROM(model: 24AA025E48T-I/OT) with a unique MAC. This EEPROM is connected to I2C0 and its address is 0x51 therefore some EEPROM chips cannot be connected to I2C0 which will cause conflicts of addresses.
- In our tests these EEPROM chips cannot be connected to I2C0: 24C04, 24C08 and 24C16. There chips which we tested can be connected to I2C0: 24C01, 24C02 and 24C256
- For more details about EEPROM address issues refer to http://www.onsemi.com/pub_link/Collateral/CAT24C01-D.PDF

- Get a 4G SDHC card and backup its data if necessary
FriendlyARM migrated both Android 5.1 and Android 4.4 to the NanoPC-T2. Android 4.4 includes features that professional users usually need: 4G, Ethernet configuration and etc.
For LCD or HDMI output use the following files: nanopi2-debian-sd4g.img.zip Debian image files nanopi2-android-sd4g.img.zip Android 5.1 image files s5p4418-kitkat-sd4g-20160803.img.zip Android 4.4 image files Flash Utility: win32diskimager.rar Windows utility. Under Linux users can use "dd"
- Uncompress these files. Insert an SD card(at least 4G) into a Windows PC and run the win32diskimager utility 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.
- Insert this card into your Smart4418's boot slot, press and hold the boot key and power on (with a 5V/2A power source). If the PWR LED is on and LED1 is blinking this indicates your Smart4418 has successfully booted.
7.2.2 Flash Image to Smart4418's eMMC
- Flash image to eMMC with eflasher
- Download eflasher
Get the eflasher utility s5p4418-eflasher-sd8g-xxx-full.img.7z and the Windows utility: win32diskimager.rar;
- Flash eflasher Image
Insert an SD card(at least 4G) into a Windows PC and run the win32diskimager utility 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.
- Flash image to eMMC
Insert this card into your Smart4418 carrier board, connect the board to an HDMI monitor or an LCD, press and hold the boot key and power on (with a 5V/2A power source) the board. After your board is powered on you will see multiple OS options and you can select an OS to start installation.
- Flash image to eMMC with RAW Image
Get the RAW image file: nanopi2-eflasher-sd4g.img.zip and the Windows utility: win32diskimager.rar;
- Flash RAW Image to SD Card
Insert an SD card(at least 4G) into a Windows PC and run the win32diskimager utility 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
- Prepare RAW image
Go to this link [1] to download Android and Debian image files(System-image-files-for-eMMC). After download extract the ".tgz" ball and copy the files to your SD card.
OS Image Files Copy to... Android 5.1 android-lollipop-images.tgz
android-lollipop-images.tgz.hash.md5boot.img
system.img

images\debian
- Specify OS
By default the SD card's configuration file "images\FriendlyARM.ini" specifies Android to be flashed to eMMC. If you want to install Debian make the following change:
OS = Debian
"#" is a comment
- Flash Image to eMMC
Insert this card into your Smart4418 carrier board, connect the board to an HDMI monitor or an LCD, press and hold the boot key and power on (with a 5V/2A power source) the board to start installation. You can watch the whole installation process from the HDMI monitor or LCD. If the following messages pop up it means the installation has succeeded.
Android is fused successfully. All done.
After installation is done do "reset" or power off and on the board to boot the board from eMMC.
- You can check the LED's status to monitor the installation process too
LED Status Installation Status LED1 blinks twice continuously
LED2 offPower on normal.
If installation doesn't proceed LED1 will keep behaving this way and LED2 will be offLED1 and LED2 blink alternatively with each blink for 0.3s Installation proceeding LED1 and LED2 blink alternatively with each blink for 1.2s Installation succeeded LED1 and LED2 blink simultaneously Installation failed
7.2.3 Make Installation Card under Linux Desktop
- 1) Insert your SD card into your host PC running Ubuntu and check your SD card's device name
dmesg | tail
Search the messages output by "dmesg" for similar words like "sdc: sdc1 sdc2". If you can find them it means your SD card has been recognized as "/dev/sdc". Or you can check that by commanding "cat /proc/partitions"
- 2) Downlaod Linux script
git clone https://github.com/friendlyarm/sd-fuse_nanopi2.git cd sd-fuse_nanopi2
- 3) Make Android SD Card
su ./fusing.sh /dev/sdx
(Note: you need to replace "/dev/sdx" with the device name in your system)
When you run the script for the first time it will prompt you to download an image you have to hit “Y” within 10 seconds otherwise you will miss the download
- 4) Here is how to make a Debian SD card
./fusing.sh /dev/sdx debian
7.2.4 Extend Smart4418's SD Card Section
- When Debian/Ubuntu boots it will automatically extend its SD card's section. On its initial booting the system will extend the root file system and other sections.
- Under Android users need to extend the section by using the following commands:
sudo umount /dev/sdx? sudo parted /dev/sdx unit % resizepart 4 100 resizepart 7 100 unit MB print sudo resize2fs -f /dev/sdx7
(Note: you need to replace "/dev/sdx" with the device name in your system)
7.2.5 LCD/HDMI Resolution
When system boots our uboot will check whether it is connected to an LCD or an HDMI monitor. If it recognizes an LCD it will configure its resolution. Our uboot defaults to the HDMI 720P configuration.
If you want to modify the LCD resolution you can modify file "arch/arm/plat-s5p4418/nanopi2/lcds.c" in the kernel and recompile it.
If your Smart4418 is connected to an HDMI monitor and it runs Android it will automatically set the resolution to an appropriate HDMI mode by checking the "EDID". If your Smart4418 is connected an HDMI monitor and it runs Debian by default it will set the resolution to HDMI 720P. If you want to modify the HDMI resolution to 1080P modify your kernel's configuration as explained above.
7.3 Update Image Files in SD Card From PC Host
If you want to make some changes to the image files in your SD card follow steps below otherwise you can skip this section.
Insert your SD card into a host PC running Linux, mount the boot and rootfs sections of the SD card and follow the steps below:
1) If you want to change your kernel command line parameters you can do it via the fw_setevn utility under "sd-fuse_nanopi2/tools":
Check the current Command Line:
cd sd-fuse_nanopi2/tools ./fw_printenv /dev/sdc | grep bootargs
Android 5.1.1_r6 starts SELinux. By default it is enforcing. You can change it this way:
./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive
This sets it to "permissive". The "XXX" stands for the original bootargs' value.
2) Update Kernel
Our customized uboot will check the LCD type when it boots.
For a non-Android OS If it recognizes an LCD connected to the Smart4418 it will load "uImage" from "boot" otherwise it will load "uImage.hdmi".
For Android it doesn't make any difference what display device is detected. You can use your generated uImage to replace the existing one under "boot".
For Debian if your generated kernel is for an LCD you need to replace the existing uImage or if your kernel is for an HDMI monitor you need to replace the existing uImage.hdmi.
7.4 Run Android or Debian
- Insert an SD card with Android/Debian image file into your Smart4418's carrier board, connect the board to an HDMI monitor, switch S2 to "SDBOOT", power on the board the Smart4418 will be booted from the SD card. If you can see the PWR LED on and the LED1 flashing it means your board is working and you will see Android/Debain being loaded on the HDMI monitor.
1) If you connect the Smart4418 to an HDMI monitor you need to use a USB mouse and a USB keyboard to operate. If you connect it to an LCD with capacitive touch you can operate directly on the LCD.
2)If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will allow you to operate the board via a serial terminal.
- Here is a setup in which we connect a Smart4418 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal
- Under Debian the password for "root" is "fa"
7.5 Login Debian via VNC or SSH
If your Smart4418 is not connected to a display device and your board runs the "-wifiap.img" image you can login to your Smart4418's nanopi2-wifiap(the default password is "123456789") via a mobile phone. You can download and install a "VNC Viewer" from here on mobile phone and login to the Smart4418 via VNC. Its default password is "fa123456". Here is a screenshot which shows how it looks like when users login to the Smart4418 from an iPhone via VNC:
You can login via "SSH -l root 192.168.8.1" too and the default password for "root" is "fa"
To make SSH session run faster turn off the WiFi's power saving mode by using the following command:
iwconfig wlan0 power off
8 Working with Debian
8.1 Ethernet Connection
- If the Smart4418 is connected to a network via Ethernet before it is powered on, it will automatically obtain an IP after it is powered up.
8.2 Wireless Connection
Open the file /etc/wpa_supplicant/wpa_supplicant.conf and append the following lines:
network={ ssid="YourWiFiESSID" psk="YourWiFiPassword" }
The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your actual ESSID and password.
Save, exit and run the following commands to connect to a WiFi:
ifdown wlan0 ifup wlan0
If your WiFi password has special characters or you don't want your password saved as plain text you can use "wpa_passphrase" to generate a psk for your WiFi password. Here is how you can do it:
wpa_passphrase YourWiFiESSID
Following the prompt type in your password and open the file /etc/wpa_supplicant/wpa_supplicant.conf you will find that your password has been changed and your can delete your plain text password.
If your AP mode is turned on you need to turn it off. You can do it by using the following commands:
su
turn-wifi-into-apmode no
8.3 Setup Wi-Fi AP
You can follow the steps below to setup Wi-Fi AP:
turn-wifi-into-apmode yes
Reboot the system as prompted. By default the AP's name is "nanopi2-wifiap" and the password is 123456789.
Now you are able to find the "nanopi2-wifiap" from a host PC and connect to it. If the connection is successful you will be able to SSH to this Smart4418 at "192.168.8.1":
ssh root@192.168.8.1
The password for it is "fa".
To make SSH run faster turn off the WiFi's power saving mode by using the following command:
iwconfig wlan0 power off
You can check the WiFi mode via the following command:
cat /sys/module/bcmdhd/parameters/op_mode
If the result is "2" it means it is currently working as a WiFi AP.If you want to switch back to the Station mode you can do it this way:
turn-wifi-into-apmode no
8.4 Bluetooth
Click on the bluetooth icon on the GUI a menu will pop up:
Make discoverable... enables the Smart4418 to be searched for by nearby bluetooth devices;
Devices... opens a search window and searches for nearby bluetooth devices(Note: the "Make discoverable" property needs to be enabled on those nearby devices);
Send Files to Device...enables the Smart4418 to send files to another bluetooth device which is paired to the Smart4418.
8.5 Install Debian Packages
We provide a Debian Jessie image. You can install Jessie's packages by commanding "apt-get". If this is your first installation you need to update the package list by running the following command:
apt-get update
You can install your preferred packages. For example if you want to install an FTP server you can do this:
apt-get install vsftpd
Note: you can change your download server by editting "/etc/apt/sources.list". You can get a complete server list from [2]. You need to select the one with "armhf".
9 Make Your Own OS Image
9.1 Install Cross Compiler
Download the compiler package:
git clone https://github.com/friendlyarm/prebuilts.git sudo mkdir -p /opt/FriendlyARM/toolchain sudo tar xf prebuilts/gcc-x64/arm-cortexa9-linux-gnueabihf-4.9.3.tar.xz -C /opt/FriendlyARM/toolchain/
Then add the compiler's directory to "PATH" by appending the following lines in "~/.bashrc":
export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH export GCC_COLORS=auto
Execute "~/.bashrc" to make the changes into effect. Note that there is a space after the first ".":
. ~/.bashrc
This compiler is a 64-bit one therefore it cannot be run on a 32-bit Linux. After the compiler is installed you can verify it by running the following commands:
arm-linux-gcc -v Using built-in specs. COLLECT_GCC=arm-linux-gcc COLLECT_LTO_WRAPPER=/opt/FriendlyARM/toolchain/4.9.3/libexec/gcc/arm-cortexa9-linux-gnueabihf/4.9.3/lto-wrapper Target: arm-cortexa9-linux-gnueabihf Configured with: /work/toolchain/build/src/gcc-4.9.3/configure --build=x86_64-build_pc-linux-gnu --host=x86_64-build_pc-linux-gnu --target=arm-cortexa9-linux-gnueabihf --prefix=/opt/FriendlyARM/toolchain/4.9.3 --with-sysroot=/opt/FriendlyARM/toolchain/4.9.3/arm-cortexa9-linux-gnueabihf/sys-root --enable-languages=c,c++ --with-arch=armv7-a --with-tune=cortex-a9 --with-fpu=vfpv3 --with-float=hard ... Thread model: posix gcc version 4.9.3 (ctng-1.21.0-229g-FA)
9.2 Compile U-Boot
Download the U-Boot source code and compile it. Note the github's branch is nanopi2-lollipop-mr1:
git clone https://github.com/friendlyarm/uboot_nanopi2.git cd uboot_nanopi2 git checkout nanopi2-lollipop-mr1 make s5p4418_nanopi2_config make CROSS_COMPILE=arm-linux-
After your compilation succeeds a u-boot.bin will be generated. If you want to test it flash it to your installation SD card via fastboot. Here is how you can do it
1) On your host PC run "sudo apt-get install android-tools-fastboot" to install the fastboot utility;
2) Connect your Smart4418 to your host PC via a serial cable (e.g. PSU-ONECOME). Press the enter key within two seconds right after you power on your Smart4418 and you will enter uboot's command line mode;
3) After type in "fastboot" and press "enter" you will enter the fastboot mode;
4) Connect your Smart4418 to this host PC via a microUSB cable and type in the following command to flash the u-boot.bin you generated:
fastboot flash bootloader u-boot.bin
Warning: you cannot update this SD card by commanding "dd". This command which will cause trouble when booting the Smart4418.
9.3 Prepare mkimage
You need the mkimage utility to compile a U-Boot source code package. Make sure this utility works well on your host before you start compiling a uImage.
You can install this utility by either commanding "sudo apt-get install u-boot-tools" or following the commands below:
cd uboot_nanopi2 make CROSS_COMPILE=arm-linux- tools sudo mkdir -p /usr/local/sbin && sudo cp -v tools/mkimage /usr/local/sbin
9.4 Compile Linux Kernel
9.4.1 Compile Kernel
- Download Kernel Source Code
git clone https://github.com/friendlyarm/linux-3.4.y.git cd linux-3.4.y git checkout nanopi2-lollipop-mr1
The Smart4418's kernel source code lies in the "nanopi2-lollipop-mr1" branch.
- Compile Android Kernel
make nanopi2_android_defconfig touch .scmversion make uImage
- Compile Debian Kernel
make nanopi2_linux_defconfig touch .scmversion make uImage
After your compilation succeeds a uImage will be generated in the "arch/arm/boot/uImage" directory. This kernel is for HDMI 720P. You can use it to replace the existing uImage.hdmi.
If you want to generate a kernel for HDMI 1080P you can do it this way
touch .scmversion make nanopi2_linux_defconfig make menuconfig Device Drivers --> Graphics support --> Nexell Graphics --> [ ] LCD [*] HDMI (0) Display In [0=Display 0, 1=Display 1] Resolution (1920 * 1080p) ---> make uImage
After your compilation succeeds a uImage will be generated for HDMI 1080P. You can use it to replace the existing uImage
9.4.2 Compile Kernel Modules
Android contains kernel modules which are in the "/lib/modules" directory in the system section. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.
Compile Original Kernel Modules:
cd linux-3.4.y make CROSS_COMPILE=arm-linux- modules
Here we have two new modules and we can compile them by following the commands below:
cd /opt/FriendlyARM/s5p4418/android ./vendor/friendly-arm/build/common/build-modules.sh
The "/opt/FriendlyARM/s5p4418/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".
After your compilation succeeds new modules will be generated
9.5 Compile Android
- Install Cross Compiler
Install 64 bit Ubuntu 14.04 on your PC host.
sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip sudo apt-get install flex libncurses5-dev zlib1g-dev gawk minicom
For more details refer to https://source.android.com/source/initializing.html 。
- Download Source Code
You need to use repo to get the Android source code. Refer to https://source.android.com/source/downloading.html 。
mkdir android && cd android repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi2-lollipop-mr1 repo sync
The "android" directory is the working directory.
- Compile System Package
source build/envsetup.sh lunch aosp_nanopi2-userdebug make -j8
After your compilation succeeds the following files will be generated in the "out/target/product/nanopi2/" directory.
filename partition Description boot.img boot - cache.img cache - userdata.img userdata - system.img system - partmap.txt - partition description file
- Flash Image to eMMC
After compiling Android successfully you can flash it to eMMC with either of the following methods
1) fastboot: right after the Smart4418 is booted from eMMC press any key to enter the uboot commandline mode and type in "fastboot"
Connect your board to a host PC running Ubuntu with a USB cable and run the following commands in the PC's terminal:
cd out/target/product/nanopi2 sudo fastboot flash boot boot.img sudo fastboot flash cache cache.img sudo fastboot flash userdata userdata.img sudo fastboot flash system system.img sudo fastboot reboot
2) Use an SD Card
Copy these files: boot.img, cache.img, userdata.img, system.img, partmap.txt from the out/target/product/nanopi2 directory to your installation SD card's images/android directory and you can use this SD card to flash Android to eMMC
10 Connect Smart4418 to External Modules
10.1 Connect Smart4418 to 4G Module
- The Smart4418 can work with some 4G modules under Android 4.4. After you connect a 4G module (e.g. ME909u-521) to a Smart4418 power on the board the 4G module will be activated automatically
10.2 Connect Smart4418 to USB Camera(FA-CAM202)
- In this use case the Smart4418 runs Debian. If you connect your Smart4418 to our LCD or an HDMI monitor after Debain is fully loaded click on "other"-->"xawtv9" on the left bottom of the GUI and the USB Camera application will be started. After enter "welcome to xawtv!" click on "OK" to start exploring.
10.3 Connect Smart4418 to CMOS 5M-Pixel Camera
- In this use case the Smart4418 runs Android5.1. If you connect your Smart4418 to our LCD or an HDMI monitor after Debain is fully loaded click on the "Camera" icon the application will be started
10.4 Use OpenCV to Access USB Camera
- The full name of "OpenCV" is Open Source Computer Vision Library and it is a cross platform vision library.
- When the Smart4418 runs Debian users can use OpenCV APIs to access a USB Camera device.
1. Here is a guideline on how to use OpenCV with C++ on the Smart4418:
- Firstly you need to make sure your Smart4418 is connected to the internet. Login to your Smart4418 via a serial terminal or SSH. After login type your username(root) and password(fa):
- Run the following commands:
apt-get update apt-get install libcv-dev libopencv-dev
2. Make sure your USB camera works with the Smart4418. You can test your camera with Smart4418's camera utility.
3. Check your camera device:
ls /dev/video*
- Note:in our test case video0 was the USB camera device
4. OpenCV's code sample(official code in C++) is under /home/fa/Documents/opencv-demo. Compile the code sample with the following commands:
cd /home/fa/Documents/opencv-demo make
After it is compiled successfully a "demo" executable will be generated
6. Connect Smart4418 to USB Keyboard & Run the Following Command
./demo
This is what you expect to observe:
