About the Boards

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

identifies the locations of the connectors and switches.

1.1 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.MX35 Applications Processor and the MC13892 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

Windows® and one BSP for Linux operating systems. These BSPs contain drivers optimized for

multimedia operations using the i.MX35 and MC13892 devices.

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

•A CPU board contains the i.MX35 CPU, memories and the MC13892 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 to demonstrate most of the i.MX35 chip functionality.. 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 7-inch WVGA display, image sensor camera, FM

receiver, SD Card connector, USB OTG, USB Host, ATA connector and TV-Out

connector, as well as additional functionality, which is described in this document.

1.2 CPU Board

Figures 1-1 and 1-2 illustrate the top and bottom of the CPU Board.

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 Personality board, (and connect the Personality board to the

Debug board) for developing software. The Personality board plugs in the other side of

the Debug board.
