BASE0033 CONNECTOR SUMMARY TABLE

Configure a static IP using the same private network range

under construction

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

The kernel command line syntax is name=value1. These next parameters are supported in igep.ini since IGEP-X_Loader 2.4.0-2:
