Note:
  1. 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 .
  2. BOOT_CS: Boot chip selection. When it is not connected or pulled up the board boots from eMMC otherwise it boots from SD card
  3. NRESETIN: Reset input. Activated when it is low. A reset signal is input to CPU from this pin
  4. NRESETOUT: Reset output. Activated when it is low. CPU's reset signal outputs to this pin.
  5. 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.
  6. ADC1~7: CPU internal ADC, 12-bit, 7 channels 1~7, range:0 ~ 1.8V
  7. 10/100M Ethernet mode: LAN_MDI1_N/P=RX-/+, LAN_MDI0_N/P=TX-/+, four pins connected to RJ45
  8. 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

  • Insert this card into your board's boot slot, press and hold the boot key (only applies to a board with onboard eMMC) and power on (with a 5V/2A power source). If the PWR LED is on and LED1 is blinking this indicates your board has successfully booted.

7.3 Flash image to eMMC with eflasher

  • Download eflasher image file

An image file's name is as : s5p4418-eflasher-OSNAME-YYYYMMDD.img.zip
The "OSNAME" is the name of an OS e.g. android, friendlycore and etc;
This image file is used for making an installation SD card and it contains a Ubuntu core system and a utility EFlasher;
Download s5p4418-eflasher-OSNAME-YYYYMMDD.img.zip to a host PC and get a windows utility win32diskimager.rar as well;

  • Make Installation SD Card with eflasher

Extract the package with a 7z utility and you will get a file with an extension ".img". Insert an SDHC card(minimum 8G or above) to a PC running Windows, run the Win32DiskImager utility as administrator, click on "Image File" to select your wanted file, select your SD card and click on "Write" to start flashing the Image to your SD card;
If your PC runs Linux you can command "dd" to extract the package and get an ".img" file and write it to your SD card;

  • Operate in GUI Window: Flash OS to eMMC

Insert your SD card to Smart4418, connect an HDMI monitor or LCD to your board, press and hold the "boot" key beside the Ethernet port, power on the board you will see a pop-up window asking you to select an OS for installation. Select your wanted OS and start installation.

  • Operate in Commandline Utility: Flash OS to eMMC

Insert an installation SD card to Smart4418, log into or SSH to your board and run the following command to start EFlasher: 

sudo eflasher

7.3.1 Make Installation Card under Linux Desktop

  • 1) Insert your SD card into a host computer 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) Here is how to make a Lubuntu desktop SD card
sudo ./fusing.sh /dev/sdx lubuntu

(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) Run this command to make a complete image file: 
sudo ./mkimage.sh lubuntu

More content please refre: Assembling the SD card image yourself

7.4 Extend SD Card Section

  • When Debian/Ubuntu is loaded the SD card's section will be automatically extended.
  • When Android is loaded you need to run the following commands on your host PC to extend your SD card's section:
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)

7.5 LCD/HDMI Resolution

When the system boots our uboot will check whether it is connected to an LCD or to 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 to an HDMI monitor and it runs Debian by default it will set the resolution to the HDMI 720P configuration. If you want to modify the HDMI resolution to 1080P modify your kernel's configuration as explained above.

7.6 Update SD Card's boot parameters From PC Host

Insert your SD card into a host PC running Linux, if you want to change your kernel command line parameters you can do it via the fw_setevn utility.
Check the current Command Line:

git clone https://github.com/friendlyarm/sd-fuse_nanopi2.git
cd sd-fuse_nanopi2/tools
./fw_printenv /dev/sdx | grep bootargs

For example, to disable android SELinux, You can change it this way: 

./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive

The "XXX" stands for the original bootargs' value.

7.7 Run Android or Linux (TODO)

  • 将制作好SD卡插入Smart4418，连接HDMI，按住靠近网口的boot按键，最后接电源(5V 2A)拨动开关，Smart4418会从SD卡启动。你可以看到板上PWR灯常亮,LED1灯闪烁，这说明系统已经开始启动了，同时电视上也将能看到系统启动的画面。
  • 要在电视上进行操作，你需要连接USB鼠标和键盘；如果你选购了LCD配件，则可以直接使用LCD上面的触摸屏进行操作。

8 Work with FriendlyCore

8.1 Introduction

FriendlyCore is a light Linux system without X-windows, based on ubuntu core, It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

Besides the regular Ubuntu core's features our FriendlyCore has the following additional features:

  • it supports our LCDs with both capacitive touch and resistive touch(S700, X710, HD702, S430, HD101 and S70)
  • it supports WiFi
  • it supports Ethernet
  • it supports Bluetooth and has been installed with bluez utilities
  • it supports audio playing
  • it supports Qt 5.10.0 EGLES and OpenGL ES1.1/2.0 (Only for S5P4418/S5P6818)

8.2 System Login

  • If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
  • If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will

For example, NanoPi-M1：
PSU-ONECOM-M1.jpg
You can use a USB to Serial conversion board too.
Make sure you use a 5V/2A power to power your board from its MicroUSB port:
For example, NanoPi-NEO2：
USB2UART-NEO2.jpg

  • FriendlyCore User Accounts:

Non-root User: 

   User Name: pi
   Password: pi

Root: 

   User Name: root
   Password: fa

The system is automatically logged in as "pi". You can do "sudo npi-config" to disable auto login.

  • Update packages
$ sudo apt-get update

8.3 Configure System with npi-config

The npi-config is a commandline utility which can be used to initialize system configurations such as user password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following command to run this utility. 

$ sudo npi-config

Here is how npi-config's GUI looks like:
npi-config

8.4 Develop Qt Application

Please refer to: How to Build and Install Qt Application for FriendlyELEC Boards

8.5 Setup Program to AutoRun

You can setup a program to autorun on system boot with npi-config: 

sudo npi-config

Go to Boot Options -> Autologin -> Qt/Embedded, select Enable and reboot.

8.6 Extend TF Card's Section

When FriendlyCore is loaded the TF card's section will be automatically extended.You can check the section's size by running the following command: 

$ df -h

8.7 Transfer files using Bluetooth

Take the example of transferring files to the mobile phone. First, set your mobile phone Bluetooth to detectable status, then execute the following command to start Bluetooth search.：

hcitool scan


Search results look like：

Scanning ...
    2C:8A:72:1D:46:02   HTC6525LVW

This means that a mobile phone named HTC6525LVW is searched. We write down the MAC address in front of the phone name, and then use the sdptool command to view the Bluetooth service supported by the phone：

sdptool browser 2C:8A:72:1D:46:02

Note: Please replace the MAC address in the above command with the actual Bluetooth MAC address of the mobile phone.
This command will detail the protocols supported by Bluetooth for mobile phones. What we need to care about is a file transfer service called OBEX Object Push. Take the HTC6525LVW mobile phone as an example. The results are as follows：

Service Name: OBEX Object Push
Service RecHandle: 0x1000b
Service Class ID List:
  "OBEX Object Push" (0x1105)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 12
  "OBEX" (0x0008)
Profile Descriptor List:
  "OBEX Object Push" (0x1105)
    Version: 0x0100

As can be seen from the above information, the channel used by the OBEX Object Push service of this mobile phone is 12, we need to pass it to the obexftp command, and finally the command to initiate the file transfer request is as follows： 

obexftp --nopath --noconn --uuid none --bluetooth -b 2C:8A:72:1D:46:02 -B 12 -put example.jpg

Note: Please replace the MAC address, channel and file name in the above command with the actual one.

After executing the above commands, please pay attention to the screen of the mobile phone. The mobile phone will pop up a prompt for pairing and receiving files. After confirming, the file transfer will start.

Bluetooth FAQ：
1) Bluetooth device not found on the development board, try to open Bluetooth with the following command：

rfkill unblock 0

2) Prompt can not find the relevant command, you can try to install related software with the following command：

apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push

8.8 WiFi

For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:

Index Model
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601
6 5G USB WiFi RTL8821CU
7 5G USB WiFi RTL8812AU

You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:

  • Change to root
$ su root
  • Check device list
$ nmcli dev

Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.

  • Start WiFi
$ nmcli r wifi on
  • Scan Surrounding WiFi Sources
$ nmcli dev wifi
  • Connect to a WiFi Source
$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.

For more details about NetworkManager refer to this link: Use NetworkManager to configure network settings

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands: 

$ apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.


8.9 Ethernet Connection

If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP refer to: Use NetworkManager to configure network settings。


8.10 Custom welcome message

The welcome message is printed from the script in this directory： 

/etc/update-motd.d/

For example, to change the FriendlyELEC LOGO, you can change the file /etc/update-motd.d/10-header. For example, to change the LOGO to HELLO, you can change the following line： 

TERM=linux toilet -f standard -F metal $BOARD_VENDOR

To: 

TERM=linux toilet -f standard -F metal HELLO

8.11 Modify timezone

For exampe, change to Shanghai timezone: 

sudo rm /etc/localtime
sudo ln -ls /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

8.12 Select the system default audio device

You can set the system default audio device by following the steps below.
Use the following command to view all the sound card devices in the system (Note: different development boards will have different results): 

pi@NanoPi:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: nanopi2audio [nanopi2-audio], device 0: c0055000.i2s-ES8316 HiFi ES8316 HiFi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: nanopi2audio [nanopi2-audio], device 1: c0059000.spdiftx-dit-hifi dit-hifi-1 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

As you can see, the following sound card devices are available on the hardware:

Sound card device Sound card number Description
nanopi2audio device 0 3.5mm jack interface
nanopi2audio device 1 HDMI

To configure the audio output to the 3.5mm jack, create or modify the configuration file /etc/asound.conf and modify it to the following: 

pcm.!default {
    type hw
    card 0
    device 0
}
 
ctl.!default {
    type hw
    card 0
}

To configure to output audio to HDMI, change the device 0 above to device 1.


8.13 Run the X11 application

FriendlyCore system built-in lightweight Xorg，although there is no window manager, you can still run a single X-Windows application，For example, the program to run is ~/YourX11App，use the following command： 

. /usr/bin/setqt5env-xcb
startx ~/YourX11App -geometry 1280x800

Note that there is a space between "." and /usr/bin/setqt5env-xcb. In addition, the resolution after -geometry should be changed to the actual resolution of your screen.

8.14 Run Qt 5.10.0 Demo with GPU acceleration

Run the following command

$ sudo qt5demo

S5pxx18-QtE

8.15 Run Qt 5.10.0 Demo with OpenGL

8.18 Power Off and Schedule Power On

“PMU Power Management” feature helps us to auto power on the board at a specific time, it is implemented by an MCU, support software power-off, and RTC alarm power-up functions.

Here’s a simple guide:
Turn on automatically after 100 seconds. (Time must be greater than 60 seconds.): 

$ sudo echo 100 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

After setting up the automatic boot, turn off board with the 'poweroff’ command: 

$ sudo poweroff

Cancel automatic boot: 

$ sudo echo 0 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

Query the current settings, in the front is current time, followed by the time of automatic booting: If no automatic boot is set, it will display "disabled”. 

$ sudo cat /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm


Note that some older versions of hardware may not support this feature, if you don't see this file node in your system:
/sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm
your board may be it does not support this feature.

9.6 Optimizing HDMI Performance on Android 7

9.6.1 Note

By default, the driver initializes two framebuffers, one for the primary LCD display and the other for HDMI. If your project specifically requires the use of HDMI and not the LCD, you can follow the steps outlined in this chapter to make modifications. After making these changes, HDMI will be configured as the primary display, resulting in the initialization of only one framebuffer. This optimization conserves resources and leads to corresponding improvements in UI performance and boot speed.
The content of this chapter is applicable exclusively to S5P6818 running Android 7. For S5P4418, the modification process is similar, with adjustments needed in the corresponding files.

9.6.2 Modify the kernel

You need to modify the kernel Device Tree Source (DTS) to disable the dp_drm_lvds node, as shown below: 

--- a/arch/arm64/boot/dts/nexell/s5p6818-nanopi3-common.dtsi

        display-timing {
                clock-frequency = <50000000>;

After compilation, you will obtain a new arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb file.
During the testing phase, you can directly update it to the board using adb with the following command: 

adb root; adb wait-for-device; adb shell mkdir /storage/sdcard1/; adb
shell mount -t ext4 /dev/block/mmcblk0p1 /storage/sdcard1/
adb push arch/arm64/boot/dts/nexell/s5p6818-nanopi3-rev*.dtb /storage/sdcard1/

For a complete firmware update, you will need to replace the files in the device/friendlyelec/nanopi3/boot directory of the Android 7 source code.

9.6.3 Modify env.conf

To modify the device/friendlyelec/nanopi3/boot/env.conf file and add a line 

lcdtype     HDMI1080P60

This mode needs to match the mode detected by Android 7 after startup; otherwise, it may result in a prolonged black screen state or even no display output. In such cases, you may need to manually set it in the U-Boot command-line environment: 

setenv lcdtype HDMI1080P60; saveenv; reset

9.6.4 Modify system.prop

To modify the device/friendlyelec/nanopi3/system.prop file in Android 7 

ro.sf.lcd_density=240

Alternatively, you can adjust the system property or experiment with different values that you deem more appropriate. You can also use the following command to change the display density under the serial or adb environment and observe if the effect is suitable: 

adb shell wm density 240

9.6.5 Compiling Android

Follow the instructions in the wiki to compile Android 7 and conduct testing. If you encounter any exceptions, please carefully review the preceding steps.

10 Make Your Own OS Image

10.1 Install Cross Compiler

10.1.1 Install arm-linux-gcc 4.9.3

Download the compiler package: 

git clone https://github.com/friendlyarm/prebuilts.git -b master --depth 1
cd prebuilts/gcc-x64
cat toolchain-4.9.3-armhf.tar.gz* | sudo tar xz -C /

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 take 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 machine. 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

10.2 Compile Linux kernel for FriendlyCore/Lubuntu/EFlasher

10.2.1 Compile Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
cd linux

The Smart4418's kernel source code is in the "nanopi2-v4.4.y" branch.You need to switch to this branch.

  • Compile Ubuntu Kernel
touch .scmversion
make ARCH=arm nanopi2_linux_defconfig
make ARCH=arm

After your compilation succeeds an "arch/arm/boot/zImage" will be generated and a DTB file(s5p4418-nanopi2-rev*.dtb) will be generated in the "arch/arm/boot/dts/" directory. You can use them to replace the existing zImage and DTB files in the boot partition of your bootable SD card.

10.2.2 Use Your Generated Kernel

  • Update kernel in SD card

If you use an SD card to boot Ubuntu you can copy your generated zImage and DTB files to your SD card's boot partition(e.g. partition 1 /dev/sdX1).

  • Update kernel in eMMC

If you boot your board from eMMC you can update your kernel file by following the steps below:
1) Usually after OS is loaded eMMC's boot partition (in our example eMMC's device name was /dev/mmcblk0p1) will be automatically mounted and you can verify that by running "mount"
2) Connect your board to a host PC running Ubuntu and copy the zImage and DTB files to eMMC's boot partition
3) Or you can copy your generated kernel file to an external storage card(e.g. an SD card or a USB drive), connect the storage card to your board the move the file from the card to eMMC's boot partition
4) After update is done type "reboot" to reboot your board. Note: don't just directly disconnect your board from its power source or press the reset button to reboot the board. These actions will damage your kernel file

  • Generate Your boot.img

Refer to this repo: https://github.com/friendlyarm/sd-fuse_s5p4418

10.3 Compile Linux kernel for Android7

The Android 7.1.2 source code already contains the pre-compiled kernel. If you need to customize it, you can compile the kernel according to the following guide. 

git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
cd linux
touch .scmversion
make ARCH=arm nanopi2_nougat_defconfig
make ARCH=arm

The newly generated kernel is arch/arm/boot/zImage，The new DTB file is also included under the directory arch/arm/boot/dts/.(s5p4418-nanopi2-rev*.dtb).
If you only want to debug the kernel, you can quickly update it with adb: 

adb root; adb shell mkdir /storage/sdcard1/; adb shell mount -t ext4 /dev/block/mmcblk0p1 /storage/sdcard1/;
adb push arch/arm/boot/zImage arch/arm/boot/dts/s5p4418-nanopi2-rev*.dtb /storage/sdcard1/

If you want to generate boot.img for burning, you can copy the kernel zImage and DTB files to the Android7 source code directory: device/friendlyelec/nanopi2/boot, then recompile Android7.

10.4 Compile U-Boot for Android7/FriendlyCore/Lubuntu/EFlasher

Download the U-Boot source code and compile it. Note that the github's branch is nanopi2-v2016.01: 

git clone https://github.com/friendlyarm/u-boot.git 
cd u-boot
git checkout nanopi2-v2016.01
make s5p4418_nanopi2_defconfig
make CROSS_COMPILE=arm-linux-

After your compilation succeeds a bootloader.img will be generated. If you want to test it flash it to your installation SD card to replace an existing U-Boot v2016.01 file via fastboot, sd-fuse_s5p4418 or eflasher ROM.
For Android7: Copy bootloader.img to Android7 source directory device/friendlyelec/nanopi2/boot, then recompile Android7.
Note: you cannot use mixed U-Boot files. For example you cannot use fastboot to update an existing U-Boot V2014.07 and you cannot use bootloader.img to replace an existing u-boot.bin

10.5 Compile Android 7.1.2

10.5.1 Install Cross Compiler

Install 64 bit Ubuntu 16.04 on your host PC. 

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex curl libncurses5-dev libssl-dev zlib1g-dev gawk minicom
sudo apt-get install openjdk-8-jdk
sudo apt-get install exfat-fuse exfat-utils device-tree-compiler liblz4-tool
