Jacinto7 J721E/DRA829/TDA4VM Evaluation Module (EVM)
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)
