Ethernet Add-on Boards

# Introduction

AM263Px Control Card(TMDSCND263P) board provides the support for Ethernet add-on boards.

1. Automotive Ethernet add-on Board(DP83TG720-EVM-AM2)
2. Industrial Ethernet add-on Board(DP83826-EVM-AM2)

The diagram below shoes the top view of AM263Px Control Card which shows the Ethernet add-on board connector.

## Important Usage Guidelines

Note
  Automotive Ethernet PHY(DP83TG720-EVM-AM2) doesn't support auto negotiation and works only in 1Gbps.
  In order to support Automotive Ethernet add-on board on AM263Px Control Card, board modifications are needed. Please refer to the Table 2-16(Ethernet Routing) in User Guide for board modifications. AM263Px Control Card Evaluation Module User's Guide (Rev. A)

In order to run Out-of-Box examples for Automotive Ethernet PHY(DP83TG720-EVM-AM2) and Industrial Ethernet PHY(DP83826-EVM-AM2), make following changes in the syscfg tool:
