To General users , pcDuino access it remotely just through the network . In fact not, you can access it remotely via USB OTG port.

There are several USB ports on pcDuino, a microUSB for the power supply, and two ordinary USB ports can insert U disk usually, you will find there is a micro USB OTG’s not be used. In fact, this micro USB would be useful. Here we teach you how to use the USB connection and computer remote SSH to pcDuino, made it into a card for computer access.[/vc_column_text][vc_tour][vc_tab title=”Recompile the kernel:” tab_id=”1387791834-1-85″][vc_column_text]

The current version of the kernel does not have this feature, after version of the kernel should be provided, and now you need to compile it yourself.

https://github.com/pcduino/kernel

Specific methods of compile kernel , refer to:

Now you put otg into your computer, the computer is responsive, but there is no driver. This driver does not need to use the wizard to install win7 drive itself comes.

Click Device Manager on the computer that has an exclamation point inside option. Right-click Update Driver Software.

Now that you’ve found the driver have been accord.

Now you put into otg on the computer, the computer is responsive , it can be identified, it is constantly acquiring IP. This is because ubuntu does not do dhcp server. Here we teach you how to do dhcp server.

modprode sw_usb_udc

modprode g_ether

ifconfig usb0 192.168.0.1 up

sudo apt-get install dnsmasq

sudo vim vim / etc / dnsmasq.conf

# Add at the end face

interface = usb0

dhcp-range = 192.168.0.11,192.168.0.12,12 h

ifconfig usb0 192.168.0.1 up

/ etc / init.d / dnsmasq restart

This time you will find that it is an error that port 53 is occupied.

netstat-utlnp

You will find that port 53 is 127.0.0.1 occupied, but the local IP. Or thank our friends, someone give a solution. As follows :

sudo apt-get remove dnsmasq-base

# This time the network will break , no relationship

ifconfig eth0 up

dhcp eth0

sudo apt-get install dnsmasq

sudo apt-get install network-manager network-manager-gnome

lsof-Pn + M | grep ‘: 53 (LISTEN)’

# See who use port 53 , there should be solved , or

netstat-utlnpnetstat-utlnp

This time again

/ etc / init.d / dnsmasq restart

Now you use ssh tool on windows can connect to pcDuino it.

Ip is usb0 use of IP.

But now there is a problem, when you plug in the computer’s external network OTG cut off. No network no pcDuino, this is definitely not enough. Here we teach you that how you can let the computer have the external network, and connect pcDuino.

Turn on the computer a command line, which at the beginning of the input cmd.

Enter the route PRINT -4 View the routing table, you find that there are two gateways.

192.168.2.1 is my router gateway, 192.168.0.1 is just to usb0 ip settings. Only need to delete usb0 this gateway on it. Perform the following operations.

Now the QQ on the computer should be on line .

We can download the flexible routing software soft X-router,link:

http://www.yitsoftware.com/XRouter/, recommended to download the free version.

After successful installation, the software will prompt you to open the log, you can directly log in without a password, and then enter the setup wizard, set here a wireless or wired laptop wlan card to mouth, set usb0 to lan port.
