1 Introduction

Overview

Front

Back

• The NanoPC-T2 quad core Cortex A9 single board computer is designed and developed by FriendlyARM for professional and enterprise users. It uses the Samsung Quad Core Cortex-A9 S5P4418 SoC with dynamic frequency scaling up to 1.4GHz. Compared to FriendlyARM's existing 4418 based boards the NanoPC-T2 has 8G eMMC onboard, audio jack and video input/output interfaces. Compared to its predecessor the NanoPC-T1 the NanoPC-T2 has built-in WiFi, Bluetooth and Gbps Ethernet port. In addition the NanoPC-T2 has power management which the NanoPC-T1 doesn't support. To avoid overheat issues the NanoPC-T2 has a heat sink with mounting posts.
• The NanoPC-T2 combines all the ports and interfaces the existing FriendlyARM 4418 boards have. Currently it has the most interfaces and ports among all existing ARM boards of this size. Its rich video interfaces and support for HDMI 1080P enable it to work with not only popular display devices but also various FriendlyARM LCDs (both resistive touch and capacitive touch).
• The NanoPC-T2 is FriendlyARM's most complete solution based on Samsung 4418 for both commercial and industrial applications.

For more details refer to the document: NanoPC-T2-Dimensions(dxf)

• Power Jack

• DC 4.7~5.6V IN, 4.0*1.7mm Power Jack

5 Notes in Hardware Design

5.1 EEPROM

• The 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

6 Get Started

6.1 Essentials You Need

Before starting to use your NanoPC-T2 get the following items ready

• NanoPC-T2
• SD Card: Class 10 or Above, minimum 8GB SDHC
• A DC 5V/2A power is a must
• HDMI monitor or LCD
• USB keyboard, mouse and possible a USB hub(or a TTL to serial board)
• A host computer running Ubuntu 16.04 64 bit system

6.2 Boot from SD Card

Get the following files from here download link:

• Get a 8G SDHC card and backup its data if necessary.
  

• 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 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.
  

6.3 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 NanoPC-T2, 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 NanoPC-T2, log into or SSH to your board and run the following command to start EFlasher:

sudo eflasher

6.3.1 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

• 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

6.4 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)

6.5 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 NanoPC-T2 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 NanoPC-T2 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.

6.6 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:

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.
