NGW/NGW100 Ethernet PHY
From AVRFreaks Wiki
Connection and usage of the two Ethernet physical (PHY) chips are summarized in the table below.
AP7000 peripheral | NGW schematic | PHY ID | Linux usage |
---|---|---|---|
MACB0 | ETH_0 | 00001 (01h) | WAN |
MACB1 | ETH_1 | 00011 (03h) | LAN |
AP7000 interfaces the PHYs with the Media Independent Interface (MII)

MAC address
The Network gateway is assigned official MAC addresses with the base 00:00:04:25:1C:50:00 +
- serial number*2 (WAN)
- serial number*2 +1 (LAN)
