i.MX31 PDK 1.4 Linux Quick Start Guide

About the Boards

This chapter provides detailed information about the three boards (CPU, Debug,

Personality) and identifies the locations of the connectors and switches.

About the 3-Stack Platform System

Freescale introduces the 3-Stack Platform System, which you use to develop multimedia

and connectivity applications using the i.MX31 Applications Processor and the MC13783

Audio and Power Management device.

The 3-Stack Platform System decreases the time between first development and final

product release by providing you (as the system designer) with a near-to-final product

design, which you can use as a development platform for software and hardware.

There are two Board Support Packages (BSP) for the 3-Stack Platform System, with one

BSP for Microsoft® Windows® and one BSP for Linux operating systems. These BSPs

contain drivers optimized for multimedia operations using the i.MX31 and MC13783

devices.

CAUTION Your PDK arrives housed in a plastic device enclosure, which under

normal circumstances you should not remove. However, the PDK

documentation set includes information for board-level components, and

also explains in some documents how to assemble the boards into the

enclosure. Should you need to work directly with the boards, use great

caution in handling the components:

– To remove or work with the boards, use static precautions.

– To remove or add the enclosure, first read the enclosure assembly instructions

carefully and note which areas are delicate.

About the Boards

About the 3-Stack Platform System

2i.MX31 PDK 1.4 Linux Quick Start Guide

Freescale's 3-Stack Platform System consists of three small boards: CPU, Debug, and

Personality.

• A CPU board contains the i.MX31 CPU, memories and the MC13783 Power

Management IC (PMIC).

• A Debug board provides the debug interfaces (like JTAG), and also has a CPLD that

implements an external Ethernet and serial controller for debug purposes.

• The Personality board implements the functionality of the 3-Stack board system, and

contains hardware for Wi-Fi® connectivity, FM receiver, and so on. The Personality

board can be modified to meet your specific requirements without the need to modify

the other two boards (CPU, Debug). The Personality board was designed to support

common multimedia applications, and has a 2.8-inch VGA display, image sensor

camera, Wi-Fi CERTIFIED™ IEEE 802.11™ b/g standards, FM receiver, SD Card

connector, USB OTG, USB Host, 2.4 QVGA smart display panel connector, ATA

connector and TV-Out connector. As the 3-Stack Platform continues to evolve, more

Personality boards will be created to meet new multimedia requirements.

Table 1.2 describes the 3-Stack Platform features in detail.

You use the J1 board-to-board connector (500 pins) to connect the CPU board to either of

the other two boards:

• Connect the CPU board to a Personality board, for running demos (no Debug board

is needed to run demos that do not use serial console commands.).

• Connect the CPU board to a Debug board, (and connect the Personality board to the

Debug board) for developing software. The Personality board plugs into the other

side of the Debug board.
