Ethernet Expansion Board
========================

PEB-C-010 Overview
------------------

The PEB-C-010 Ethernet Expansion Board is a PHYTEC accessory designed to expand the Ethernet capabilities of the phyBOARD-Electra AM64x. It allows developers to evaluate industrial Ethernet communication protocols—such as EtherCAT and PROFINET—directly on their development setup.

This guide explains how to connect, configure, and use a single PEB-C-010 board to test the additional Ethernet PHY interfaces.

Key Features
------------

- Adds two additional industrial Ethernet ports (ETH3 and ETH4)
- Supports EtherCAT and PROFINET evaluation

Attaching the phyBOARD-Electra AM64x and PEB-C-010
--------------------------------------------------

**Required Components**

- phyCORE-AM64x System on Module (SoM)
- phyBOARD-Electra AM64x Carrier Board
- PEB-C-010 Ethernet Expansion Board
- 12 V Barrel Power Adapter (included with the Development Kit)

The PEB-C-010 is designed to plug directly into the phyBOARD-Electra AM64x via the **X28** expansion header.

Software Setup – Enabling the Overlay
-------------------------------------

To activate the additional Ethernet interfaces provided by the PEB-C-010, a Device Tree Overlay must be enabled. This overlay file is included in the PHYTEC Linux BSP for the phyCORE-AM64x.

.. note::
   See |ref-build-bsp| for instructions on building the BSP.

To enable the overlay, interrupt the boot process at the U-Boot prompt and enter the following commands:

.. code-block:: console
   :substitutions:

   |uboot-prompt| setenv overlays k3-am642-phyboard-electra-peb-c-010.dtbo
   |uboot-prompt| saveenv
   |uboot-prompt| boot
