4 Get Started

4.1 Essentials You Need

Before starting to use your NanoPi A64 get the following items ready

  • NanoPi A64
  • microSD Card/TFCard: Class 10 or Above, minimum 8GB SDHC
  • microUSB power. A 5V/2A power is a must
  • HDMI monitor
  • USB keyboard and mouse, and a USB HUB would be better
  • A Host computer running Ubuntu 14.04 64 bit system

4.2 TF Cards We Tested

To make your NanoPi A64 boot and run fast we highly recommend you use a Class10 8GB SDHC TF card or a better one. The following cards are what we used in all our test cases presented here:

  • SanDisk TF 8G Class10 Micro/SD TF card:

SanDisk MicroSD 8G

  • SanDisk TF128G MicroSDXC TF 128G Class10 48MB/S:

SanDisk MicroSD 128G

  • 川宇 8G C10 High Speed class10 micro SD card:

chuanyu MicroSD 8G

4.3 Make an Installation TF Card

4.3.1 Get Image File

Get the following files from download link to download image files (under the officail-ROMs directory) and the flashing utility(under the tools directory):

Image Files
nanopi-a64-core-qte-sd4g.img.zip a Light Ubuntu-core system with a Qt Embedded GUI library
nanopi-a64-ubuntu-mate-sd4g.img.zip Ubuntu with a MATE-desktop
Flash Utility:
win32diskimager.rar Windows utility. Under Linux users can use "dd"
PhoenixCard_V310.rar Windows utility for flashing Android image. Attention: the "dd" command under Linux doesn't work for flashing Android image
HDDLLF.4.40.exe Windows utility for formatting a TF card

4.3.2 Make Ubuntu-Core Image Card

  • Extract the nanopi-a64-core-qte-sd4g.img.zip and win32diskimager.rar files. Insert a TF card(at least 4G) into a Windows PC and run the win32diskimager utility as administrator. On the utility's main window select your TF card's drive, the wanted image file and click on "write" to start flashing the TF card.
  • After this writing process is done insert this card into your NanoPi A64's TF card slot and power on (with a 5V/2A power source). If the green LED is on and the blue LED is blinking this indicates your NanoPi A64 has successfully booted.

5 Work with Ubuntu-Core

5.1 Run Ubuntu-Core

  • Insert a TF card with UbuntuCore image files into your NanoPi A64, connect the board to a 5V/2A power source the board will be automatically powered on. If you can see the blue LED flashing it means your board is working and UbuntuCore is being loaded.

1) To make it easy you can connect an HDMI monitor, a USB mouse and keyboard to your A64 board. 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 A64 to a PC via the PSU-ONECOM and you can power on your A64 from either the PSU-ONECOM or the board's MicroUSB:

PSU-ONECOM-NEO

  • It has two user names: root and fa and the password for both is "fa".
  • Update packages
sudo apt-get update

5.2 Extend TF Card's Section

We strongly recommend you to do this right after you have made an installation TF card since this will greatly enhance your A64's experience

  • Extend your card's rootfs section under a host PC:
sudo umount /dev/sdx?
sudo parted /dev/sdx unit % resizepart 2 100 unit MB print
sudo resize2fs -f /dev/sdx2

Note: you need to replace "/dev/sdx" with the device name in your system.

5.3 Login via SSH

If your NanoPi A64 is connected to a network via Ethernet before it is powered on it will automatically obtain an IP after it is powered up. If it is not connected via Ethernet or its DHCP is not activated obtaining an IP will fail and system will hang on for about 15 to 60 seconds. You can log into the board via SSH. In our test the IP address detected by our router was 192.168.1.230 and we ran the following command to log into the NanoPi NEO: 

ssh root@192.168.1.230

The password is fa。


5.4 HDMI输出声音

Ubuntu-core系统默认从3.5mm耳机座输出声音，想从HDMI输出需要修改文件系统上的配置文件/etc/asound.conf如下： 

pcm.!default {
    type hw
    card 1
    device 0
}
 
ctl.!default {
    type hw
    card 1
}

card 0代表3.5mm耳机孔，card 1代表HDMI音频。设置完成后需要重启系统才能生效。

5.5 连接WiFi

用vi或在图形界面下用gedit编辑文件 /etc/wpa_supplicant/wpa_supplicant.conf, 在文件末尾填入路由器信息如下所示： 

network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}

其中，YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码。
保存退出后，执行以下命令即可连接WiFi: 

ifdown wlan0
ifup wlan0

如果你的WiFi密码中有特殊字符，或者你不希望明文存放密码，你可以使用wpa_passphrase命令为WiFi密码生成一个密钥(psk)，用密钥来代替密码 ，在命令行下，可输入以下命令生成密钥: 

wpa_passphrase YourWiFiESSID

在提示输入密码时，输入你的WiFi密码，再打开 /etc/wpa_supplicant/wpa_supplicant.conf 文件你会发现密钥已经被更新，你可以删除明文的密码了。
