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
Naon[edit | edit source]
The following variables applies to Naon CPU module. Please note that the this variable refers to U-Boot and Linux provided with NELK version 4.0.0.
naon_host [evb_mid | evb_lite] - Selects carrier board pinmux. Please refer to U-Boot source tree for the available pinmux.
Maya[edit | edit source]
The following variables applies to Maya CPU module. Please note that the this variable refers to U-Boot and Linux provided with NELK version 4.0.0.
naon_host [maya_naon_evb_lite] - Selects carrier board pinmux. Please refer to U-Boot source tree for the available pinmux.
Dido[edit | edit source]
The following variables applies to Dido CPU module. Please note that the this variable refers to U-Boot and Linux provided with NELK version 4.0.0.
addmem = 'setenv bootargs ${bootargs} mem 364M mem=320M@0x9fc00000 mem=1020M@0xc0000000 vmalloc=500M' - Dido 2 GB memory
naon_host [evb_mid | evb_lite] - Selects carrier board pinmux. Please refer to U-Boot source tree for the available pinmux.
