UDOO configure Ethernet under Android
To configure Ethernet connection on UDOO under Android 4.2.2 you need to connect the board to a host computer. You need to plug a microUSB cable to i.MX6 debug serial UART on CN6 microUSB port. With a serial monitor it's possible to communicate with Android shell over serial uart.
DHCP
When you connect the Ethernet cable the DHCP mode is selected by default.
Static Address
To configure a static ip address you need to open the i.MX6 debug console. Use the following command to set a static ip and a subnet mask:
ifconfig eth0 [YOUR_IP_ADDRESS] netmask [NETMASK]
Then configure the gateway ip using this command:
ip route add default via [GATEWAY_IP] dev eth0
DNS
To set different DNS you need to change the environment properties:
setprop net.dns1 [PRIMARY_DNS_IP_ADDRESS] setprop net.dns2 [SECONDARY_DNS_IP_ADDRESS]
