1 Introduction

The Jacinto7 J721E (DRA829/TDA4xM) EVM is a standalone test, development, and evaluation module system that enables developers to write software and develop hardware around Jacinto7 J721E (DRA829/TDA4xM) processor subsystem. The J721E processor is a KeyStone™ III-based Multicore Arm® System-on-Chip (SoC). It is a super-set processor/device and may be available is different configurations targeted for specific markets. This EVM will support development of the super-set device (J721E) as well as the market specific devices (DRA829/TDA4xM). Many features of the J721E system are available on the EVM, which gives developers the basic resources needed for most general-purpose type.

The J721E EVM is comprised of:

  • J721E System On Module (SOM) board
  • Jacinto7 Common Processor Board (CPB)
  • Quad-Port Ethernet board (QPENet)

J721E EVM sub system has been designed to enable customers to evaluate the Processor’s performance with flexibility. To have flexibility while developing the system, different interface/expansion boards have been designed. Some examples include:

  • Infotainment Expansion Board
  • Gateway/Ethernet Switch/Industrial (GESI) Expansion Board
  • Fusion CSI2 Expansion Board(s)
