Table 4-26

provides information about the Ethernet interface.

See the LAN9118 data sheet or the self-test program supplied on the Versatile Express DVD for
additional information.

When manufactured, ARM values for the Ethernet MAC address and the register base address
are loaded into the EEPROM. The register base address is 0 and the unique MAC address is
displayed on a sticker on the motherboard. The default MAC address can be temporarily
overwritten by the value in the

config.txt

file. See the
