Get Started

Essentials You Need

Before starting to use your NanoPi Fire3 get the following items ready

  • NanoPi Fire3
  • 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 14.04 64 bit system

Make an Installation SD Card

Boot NanoPi Fire3 from SD Card

Get the following files from here to download necessary files:

  • Get a 8G SDHC card and backup its data if necessary
Image Files:
s5p6818-debian-sd4g-YYYYMMDD.img Debian image files
s5p6818-android-sd4g-YYYYMMDD.img Android image files
s5p6818-FriendlyCore-Xenial-4.4-YYYYMMDD.img Ubuntu Core + QT image files
Flash Utility:
win32diskimager.rar Windows utility. Under Linux users can use "dd"
  • Uncompress these files. Insert an SD card(at least 8G) 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 NanoPi Fire3'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 NanoPi Fire3 has successfully booted.

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_s5p6818.git
cd sd-fuse_s5p6818
  • 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

Extend NanoPi Fire3's 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)

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-s5p6818/nanopi3/lcds.c" in the kernel and recompile it.
If your NanoPi Fire3 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 NanoPi Fire3 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.

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 the 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_s5p6818/tools". Check the current Command Line:

cd sd-fuse_s5p6818/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 Android it doesn't make any difference which 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.

Run Android or Debian

  • Insert an SD card with Android/Debian image file into your NanoPi Fire3, connect the board to an HDMI monitor, press and hold the boot key, power on the board the NanoPi Fire3 will boot 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 NanoPi Fire3 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 where we connect a NanoPi Fire3 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal:

PSU-ONECOM02

  • Under Debian the password for "root" is "fa"

Working with Debian

Ethernet Connection

  • If the NanoPi Fire3 is connected to a network via Ethernet before it is powered on, it will automatically obtain an IP after it is powered up.

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 [1]. You need to select the one with "armhf".

Ubuntu-Core with Qt-Embedded

Introduction

Ubuntu Core with Qt-Embedded is a light Linux system without X-windows. It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

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

  • it supports our LCDs with both capacitive touch and resistive touch(S700, X710, S70)
  • it supports WiFi
  • it supports Ethernet
  • it supports Bluetooth and has been installed with bluez utilities
  • it supports audio playing

Make Your Own OS Image

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 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
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

...
Thread model: posix
gcc version 4.9.3 (ctng-1.21.0-229g-FA)

Compile U-Boot

Download the U-Boot source code and compile it. Note that 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 s5p6818_nanopi3_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 NanoPi Fire3 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 NanoPi Fire3 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 NanoPi Fire3 to this host PC via a microUSB cable and type in the following command to flash u-boot.bin:

fastboot flash bootloader u-boot.bin


Warning: you cannot update this SD card by commanding "dd". This command will cause trouble when booting the NanoPi Fire3.

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

Compile Linux Kernel

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 NanoPC-T3's kernel source code lies in the "nanopi2-lollipop-mr1" branch.

  • Compile Android Kernel
make nanopi3_android_defconfig
touch .scmversion
make uImage
  • Compile Debian Kernel
make nanopi3_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 LCD output. You can use it to replace the existing uImage.
If you want to generate a kernel for HDMI output you need to run nanopi3_linux_hdmi_defconfig and do it this way:

make nanopi3_linux_hdmi_defconfig
touch .scmversion
make menuconfig

After your compilation succeeds a uImage will be generated for HDMI 720P. If you want a uImage for 1080P you can do it this way:

touch .scmversion
make nanopi3_linux_hdmi_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.hdmi.

  • Compile Kernel for Ubuntu Core

The steps here are nearly the same as the steps for compiling a Debian kernel:
LCD Output:

make nanopi3_core-qt_defconfig

HDMI Output:

make nanopi3_core-qt_hdmi_defconfig

Select your configuration file and run the following commands to generate a uImage.

touch .scmversion
make uImage

Use Your Generated Kernel

  • Update the kernel file in SD card

If you use an SD card to boot Android you can copy your generated uImage file to your SD card's boot section(e.g. section 1 /dev/sdX1).
If you use an SD card to Debian and you generated a uImage for an HDMI monitor you can use that uImage to replace the uImage.hdmi file in the SD card's boot section. If you use an SD card to Debian and you generated a uImage for an LCD you can use that uImage to replace the uImage file in the SD card's boot section.

  • Update Android kernel file in eMMC

If you want to update the kernel file in eMMC you need firstly boot your board, then mount eMMC's boot section, replace the boot section's kernel file with your generated one and reboot your board to make your new kernel run.
If you boot your board from eMMC you can update your kernel file by following the steps below:
1) After Android is loaded mount eMMC's boot section (in our example eMMC's device name was /dev/mmcblk0p1) by using the following commands:

su
mount -t ext4 /dev/block/mmcblk0p1 /mnt/media_rw/sdcard1/

2) Connect your board to a host PC running Ubuntu and copy the uImage file to eMMC's boot section by running the following commands;

adb push uImage /mnt/media_rw/sdcard1/

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 section;
4) After update is done type in "reboot" to reload Android. Note don't directly power off and on the board or press the reset button to reboot the board. These two actions will damage your kernel file.

  • Update Debian kernel file in eMMC

If you boot your board from eMMC you can update your kernel file by following the steps below:
1) When Debian is being loaded eMMC's boot section will be automatically mounted(in our example eMMC's device name was /dev/mmcblk0p1). You can use "mount" to verify that;
2) Connect your board to a host PC via Ethernet and copy your generated uImage file via scp/ftp to eMMC's boot section and replace the existing file. If your file is for an LCD use your uImage file to replace the existing uImage. If your file is for an HDMI monitor use your uImage.hdmi file to replace the existing uImage.hdmi file;
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 section;
4) After update is done type in "reboot" to reload Debian. Note don't directly power off and on the board or press the reset button to reboot the board. These two actions will damage your kernel file

  • Generate Your boot.img

If you want to generate an image file that can be flashed to eMMC you need to generate a boot.img file and copy it to your installation SD card.
For Android copy the uImage file to Android source code's "device/friendly-arm/nanopi3/boot/" directory and compile this whole Android source code. After your compilation is successful you will get a boot.img file.
For Debian follow the steps below to generate a boot.img file:
1) Download debian_nanopi2

git clone https://github.com/friendlyarm/debian_nanopi2.git

2) Copy the image file for an HDMI monitor and use it to replace the "debian_nanopi2/boot/uImage.hdmi" file and copy the image file for an LCD and use it to replace the "debian_nanopi2/boot/uImage" file;
3) Generate Debian's boot.img

cd debian_nanopi2
mkdir rootfs
./build.sh

A newly generated boot.img will be under the "debian_nanopi2/sd-fuse_nanopi2/debian" directory.
The "mkdir rootfs" command creates a working directory for the build.sh script to run. It also creates some files such as "rootfs.img" but these files are useless.

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/s5p6818/android
./vendor/friendly-arm/build/common/build-modules.sh

The "/opt/FriendlyARM/s5p6818/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

Compile Android

  • Install Cross Compiler

Install 64 bit Ubuntu 14.04 on your host PC.

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex 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 nanopi3-lollipop-mr1
repo sync

The "android" directory is the working directory.

  • Compile System Package
source build/envsetup.sh
lunch aosp_nanopi3-userdebug
make -j8

After your compilation succeeds an image will be generated in the "out/target/product/nanopi3/" directory.

filename partition Description
boot.img boot -
cache.img cache -
userdata.img userdata -
system.img system -
partmap.txt - partition file
  • Flash Image to SD Card

If you want to boot your board from an SD card you need to copy your generated image file to the "sd-fuse_s5p6818 /android/" directory and flash it to your SD card with our script. For more details refer to # Make an Installation SD Card under Linux Desktop
