Ethernet Controller
The dimmPCI
TM
contains an on board RealTek RTL8019AS Ethernet controller and all the
supporting circuitry to implement a 10BaseT ethernet port with no external components. The
drivers have been written and implemented by the µClinux operating system running on the
dimmPCI
TM
. No support is provided with the exception of the AMC Technologies Corporation
provided IEEE assigned MAC address. Below shows how the MAC address can be obtained.
The ethernet 8-bit peripheral is attached to the 16-bit chipset via chip select CSA1 as explained in
the memory map section.
Viewing the Ethernet MAC ID
One way to view the MAC ID is to simply reboot. One of the boot messages that scroll past
displays the MAC ID.
A utility exists called ‘ifconfig’ that when executed displays the current network information.
‘ifconfig’ displays “hwaddr” which is the MAC ID of the module. There are two utilities to set
the IP address as outlined in Section 3.
