STK1000/Ethernet PHY and connectors
From AVRFreaks Wiki
The Ethernet subsystem on STK1000 let you test applications that use Ethernet for connectivity to other computers.
STK1000 provide a flexible solution with a dual Ethernet physical layter chip (PHY) to allow testing of both Media Independent Interface (MII) and Reduced Media Independent Interface (RMII). The two Ethernet interfaces each have a RJ45 Ethernet connector and are named ETH_A and ETH_B. These Ethernet interfaces are connected to the Media Access Control (MAC) 0 and 1 respectively.
Notes to developers
MAC addresses
The MAC addresses of the two Ethernet interfaces can be calculated from the following formula. These MAC addresses belong to Atmel corporation and are set aside for use with STK1000.
- MAC0 = 00-04-25-19-00-00 + 2x(serial number)
- MAC1 = 00-04-25-19-00-00 + 2x(serial number) + 1
Note that the serial number in the formula is the serial number found underneath STK1000.
