IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)
 +
 
 +
*eth0 − 192.168.5.1
 +
*eth0:0 − assigned via dhcp.
 +
 
 +
This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.
 +
 
 +
But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to

This How-To is meant to be a starting point for people to learn use GPIOs for IGEP devices as quickly and easily as possible. For this How-To I used [http://labs.isee.biz/index.php/IGEP_firmware_Yocto IGEP firmware Yocto]
