Assembly and configure NanoPi NEO2

The NanoPi NEO2 is a newly released super tiny ARM board by FriendlyElec. It uses Allwinner’s 64-bit H5 quad-core SoC (ARM Cortex-A53). It has internal hexa-core Mali450 GPU, 512M DDR3 RAM. A UbuntuCore and Armbian image files are ready for it.
The NanoPi NEO2 inherits NEO's form factor and has compatible interfaces and ports with NEO. In addition in such a small dimension it has Gbps Ethernet and one USB host port. These features make it especially suitable for applications that require high data throughput, speedy data transmission and high performance. Hobbyists and makers will just love it.

OS/Software: u-boot, Ubuntu Core.

Unpacking and assembly

Glue the thermal conductive gasket in a special place on the bottom of the housing;

Peel off the transparent protective film from the gasket, carefully install the Board Nano NEO2 in the body and fasten the board to the body part using two small bolts (M1.6x3mm) from the kit;

Gently plug NanoHat OLED module on the NanoPi NEO2 board;

Put on the table the top of the body and install the three round buttons in special holes;

Remove the protective film from the screen, carefully connect the two parts of the body and screw both parts of the body with long bolts (M2.5x23mm) from the kit;

Then turn over the body and glue the rubber feet in special places on the body, by the way, pay attention to the thread M3 in these special places (if necessary, the body can be screwed somewhere).

The result is something like this:

Software

Open the link http://download.friendlyarm.com/nanopineo2 and click on the Google Drive icon. Then go to the folder official-ROMs and select the image file. Because I have version NanoPi NEO2 with OLED screen, I download the image nanopi-neo2_sd_ubuntu-oled-xenial_4.14_arm64_20181011.img.zip from accessory-ROMs folder.

$ unzip nanopi-neo2_sd_ubuntu-oled-xenial_4.14_arm64_20181011.img.zip
$ dd if=nanopi-neo2_sd_ubuntu-oled-xenial_4.14_arm64_20181011.img of=/dev/disk2

If you connect the microSD card that came with the kit (or that we just recorded) to another linux computer (Synology for example) and see what's on it, we'll see something like this:

As we can see, the first partition has a size of 100 megabytes – FAT32 file system, on this partition there is a bootloader. And the second partition with size 2.4 GiB – file system ext4 with pre-installed Linux.

First switch on

NanoPi NEO2 connected to the network cable and the power cable with a micro USB connector. The device turns on, receives an IP address from the DHCP server after a few seconds, then the display lights up after a few seconds. The screen shows the wrong date and time, and after a couple of seconds, the date and time are corrected to the actual (adjusted for the wrong default time zone).

The default buttons work as standard:

F1 – displays the current date and time on the screen;
F2 – displays system information with IP address, CPU load, amount of free / installed RAM, disk space and CPU temperature;
F3 – shutdown NanoPi NEO2 (in this mode, pressing F1 changes the menu item Yes / No, and pressing F2 acts as the Enter button).

As we saw in parted section with pre-installed Linux was slightly less in size than 4GB, but after the first boot partition is expanded to 15GB. This is done in order to be able to take to install any microSD-card from 4GB and above, copy the image to it with preinstalled Linux, and boot. And then after the first boot, the size of the root partition increases to the maximum of the installed microSD card.

By the way, if NanoPi NEO2 is not connected to the power supply, but to any other computer, NanoPi NEO2 will be defined as a USB-device, and even the first partition with the bootloader will be available for reading:

Renaming default users pi and fa:

NanoPi-NEO2:~# ps --user pi
  PID TTY          TIME CMD
  742 ?        00:00:00 systemd
  744 ?        00:00:00 (sd-pam)
  748 tty1     00:00:00 bash
  749 ttyS0    00:00:00 bash

NanoPi-NEO2:~# systemctl stop getty@tty1.service
Warning: getty@tty1.service changed on disk. Run 'systemctl daemon-reload' to reload units.
NanoPi-NEO2:~# systemctl stop serial-getty@ttyS0.service
Warning: serial-getty@ttyS0.service changed on disk. Run 'systemctl daemon-reload' to reload units.
NanoPi-NEO2:~# systemctl daemon-reload
NanoPi-NEO2:~# ps --user pi
  PID TTY          TIME CMD

NanoPi-NEO2:~# usermod --login newuser --home /home/newuser --move-home pi
NanoPi-NEO2:~# groupmod --new-name newgroup pi
NanoPi-NEO2:~# find /etc/systemd/ -name autologin.conf -exec sed -i "s/\bpi\b/newuser/g" {} \;
NanoPi-NEO2:~# systemctl daemon-reload

In the same way, you must rename the user fa.

Locale configuring:

NanoPi-NEO2:~# echo en_US.UTF-8 UTF-8 >/var/lib/locales/supported.d/en
NanoPi-NEO2:~# nano -w /etc/locale.gen
en_US.UTF-8 UTF-8
ru_RU.UTF-8 UTF-8
NanoPi-NEO2:~# locale-gen
Generating locales (this might take a while)...
  en_US.UTF-8... done
  ru_RU.UTF-8... done
Generation complete.

If not fix file /var/lib/locales/supported.d/en, then an additional 15 extra locales will be created.

Timezone configuring:

NanoPi-NEO2:~# dpkg-reconfigure tzdata

General setup with the official utility:

NanoPi-NEO2:~# npi-config

8 About npi-config     Information about this configuration tool

Update and restart the operating system:

NanoPi-NEO2:~# apt update
NanoPi-NEO2:~# apt upgrade
NanoPi-NEO2:~# reboot

Installing additional utilities and setting up a working environment in bash:

NanoPi-NEO2:~# apt install mc bash-completion curl htop pinfo screen usbutils

Next, you can configure the working environment in bash by this note. And if you need to connect to NanoPi NEO2 using the serial console port for debugging, use the information from this note.

Update: After a couple of weeks of using the device, it turned out that OLED-display has already started to burn out, so it is highly desirable immediately after purchase and installation to turn on the sleep timer for the display. Here describes how to do it.
