AMC 68VZ328 software manual Ethernet Controller, Viewing the Ethernet MAC ID

Ethernet Controller

The dimmPCITM 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 dimmPCITM. 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.
