Chapter 1
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.

NOTE
You can use other Linux distributions (they should be based
on the ones listed above). However, default configuration
(tools, packages, modules, shells, etc.) may be different and
you would need to set your host up accordingly for the
i.MX35 PDK Linux BSP to work properly. Also, Linux OS
can be installed on a virtual machine so you can use both
Windows and Linux on the same host (recommended only for
testing).
