[[AN-BELK-006:_Enabling_dual_Gigabit_Ethernet_support_on_BoraEVB/BoraXEVB | AN-BELK-006]] shows how to enable second Ethernet interface by the use of native Gem1 GEM1 controller. That application note allows to support both Ethernet ports in Linux. In some circumstances, it can be required to access second Ethernet port in U-Boot as well.
This white paper describes how to use both Ethernet ports in U-Boot. It is worth remembering that '''default U-Boot delivered with Bora Embedded Linux Kit or BoraX Embedded Linux Kit does not support second Ethernet interface'''. A modified version is required to run the examples presented here. For more information please contact [mailto:support-bora@dave.eu|technical support].
