About the Boards
This chapter provides detailed information a bout the three boards ( CPU, Debug,
Personality) and the locations of th e connectors and switches for each.
CAUTION Your PDK arrives housed in a plastic device enclosure, which under
normal circumstances you should not rem ove. However, the PDK
documentation set includes informat ion 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, please 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, such as the speakers.

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.MX27 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 syst em 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 Embedded CE™ 6.0, and one BSP for Linux operating systems. These
BSPs contain drivers optimized for multimedi a operations using the i.MX27 and
MC13783 devices.
Freescale's 3-Stack Platform System consists of three small boards: CPU, Debug, and
Personality.
• A CPU board contains the i.MX27 CPU, memories, and the MC13783 Power
Management IC (PMIC).
• A Debug board provides the debug interfaces (such as JTAG), and also has a CPLD
that implements an external Ethernet an d serial controller for debug purposes.
• The Personality board implements the functionality of the 3-Stack board, and
contains hardware for Wi-Fi connectivi ty, FM receiver, and so on. The Personality
board can be modified to meet your speci f ic req ui reme nt s wi thout the nee d to m odify
the other two boards (CPU, Debug). The Personality board was designed to support
