Flash Ubuntu on NAO v6

Instructions to install the ubuntu based operating system created by the NaoDevils team on a Nao V6.

Prerequisites

Download the Softbank official firmware, in particular version 2.8.5.10 is required. The file should be something like nao-2.8.5.10.opn

You need two usb drives with a capacity of 4GB and 8 GB at least.

The following instructions are based on an ubuntu system.

Inside the assets/flasher-2.1.0.19-linux64 folder launch a terminal and run
```
sudo ./flasher
```
Using the gui, flash the nao-2.8.5.10.opn file on your usb drive with at least 4GB.
Using the official firmware, follow the instruction reported on the Nao Devils NaoImage github page to make a bootable usb with the ubuntu image.
Switch off nao and insert the first usb you created with the official firmware with root.
Switch on nao pressing the button until it flashes blue very rapidly. Wait some minutes until it stands up and moves.
Switch off nao and insert the second usb with the ubuntu image. Repeat the flashing procedures.
If everything is fine nao is not moving and lights are on.

To connect to nao you need to connect it via ethernet to a router.

Access the router admin page and discover the nao assigned ip address.
Connect to it via ssh, the username and password are ''nao''
To modify the nao network settings, edit the file /etc/netplan/default.yaml
```
sudo nano /etc/netplan/default.yaml
```
A sketch of a setting enabling a wifi connection is available in nao_network.yaml
Apply the changes
```
sudo netplan apply
```
If everything is fine you can now connect to nao via wifi using the choosen static ip address.
Check internet connection
```
ping 8.8.8.8
```
