About the Boards
This chapter provides detailed information about the three boards (CPU, Debug, 
Personality) and the locations of the connectors and switches for each. 
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, 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 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 Embedded CE™ 6.0, and one BSP for Linux operating systems. These 
BSPs contain drivers optimized for multimedia 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 and serial controller for debug purposes. 
• The Personality board implements the functionality of the 3-Stack board, 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
