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)
