Introduction[edit | edit source]

This page describes the U-Boot environment variables that specifically applies to certain Dave SOMs.

Naon Family[edit | edit source]

The following variables applies to Naon, Maya and Dido SOMs. Please note that the this variables refers to U-Boot and Linux provided with NELK version 4.0.0.

ethaddr = xx:xx:xx:xx:xx:xx - MAC address for eth0 interface
ethaddr1 = xx:xx:xx:xx:xx:xx - MAC address for eth1 interface 
dual_emac = [0|1] - [0: CPSW switch mode | 1: CPSW dual EMAC mode]
cpsw = [0|1] - select primary phy for networking operations in U-Boot [0: phy 6 -> 100Mbit Naon module | 1: phy 1 -> 1Gbit external, EVB-Lite and EVB-Mid]
giga = [on] - if present, select gigabit speed on gigabit link
