4 Get Started

4.1 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

4.2 Make an Installation SD Card

4.2.1 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.

4.2.2 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

4.2.3 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)

4.2.4 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.

4.3 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 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.

4.4 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"
