# Ethernet Low Level Drivers

Introduction

The Unified Ethernet Low-Level Driver (Enet LLD) is a driver that aims at providing an unified interface for the different Ethernet peripherals found in Sitara MCU+ class of devices from Texas Instruments. These devices currently include:

• AM2431, AM2432, AM2434
• AM2634, AM2634-Q1
• AM2732
• AM6411, AM6412, AM6421, AM6422, AM6441, AM6442

Features

• Supports both CPSW and ICSSG peripherals.
• Provided with pre-built ICSS firmware binary for ICSS PRU.
• Provides control and datapath (DMA) programming Interfaces for application.
• Integrated with LwIP adaptation layer to interface with LwIP networking stack.
• Operating syhstem agnostic. Currently Supports FreeRTOS and bare metal (NoRTOS) applications.
• Includes drivers to support the below Ethernet PHY transceiver along with any other generic Ethernet PHY transceivers that can be modified to support various other Ethernet PHY transceivers.
  • DP83822
  • DP83867
  • DP83869
  • VSC8514
• Currently, supports below distinguished features apart from basic Ethernet features.
  • AM243x: MAC Mode, Switch Mode, Timestamping, multi-channel, DSCP, Policer and Rate Limiters, TCP/IP checksum offload.
  • AM263x: MAC Mode, Switch Mode, Timestamping, multi-channel, DSCP, TSN-EST, Policer and Rate Limiters, Interrupt Pacing, Tx Scatter-Gather, TCP/IP checksum offload.
  • AM273x: Timestamping, multi-channel, DSCP, TSN-EST, Policer and Rate Limiters, Interrupt Pacing, Tx Scatter-Gather, TCP/IP checksum offload.
  • AM64x: MAC Mode, Switch Mode, Timestamping, multi-channel, DSCP, Policer and Rate Limiters, TCP/IP checksum offload.

Overview

The Enet LLD is composed of the following layers: top-layer APIs, peripheral layer, module layer and CSL. CSL layer has SOC specific hardware register defination and it is part of MCU_PLUS_SDK repository

Usage

Enen though enetLLD is a seperate repository, it is not independent. It has dependencies to other repositories such as MCU_PLUS_SDK, FreeRTOS and LwIP. It uses the build system from MCU_PLUS_SDK and hence please refer to MCU_PLUS_SDK for instructions about compilation, documentation generation and usage.
