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.M31 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 WinCE and one BSP for Linux operating systems. These BSPs contain drivers
optimized for multimedia operations using the i.MX31 and MC13783 devices.
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 WiFi 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

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.

Figure 1.1 CPU Board
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).
• 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.
Software • Sample Windows® embedded CE binary image
