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

1

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

6. The OS image pre-loaded in the 3-Stack board will boot and the debug messages from
the bootloader should now appear on the serial console application on your PC.

Build a Demo Platform: Assemble 2 Boards

This section explains how to make a demonstration platform using the Personality and
CPU boards.

To make a demonstration platform, the CPU board is directly connected to the Personality
board using the 500-pin connector; the Debug board is not used.

NOTE I f your system is already configured as a development platform (using all three

boards), disconnect all boards from one another.

Downloading Multimedia to the 3-Stack Board

Downloading Multimedia to the 3-Stack
Board

Downloading the multimedia content to the 3-Stack board requires the following items:

• An SD card -After the SD card is plugged in, you may load the multimedia files
from a PC if the USB Mass Storage Application is launched.

• (Optional) the USBS Mass Storage Application

• A serial connection between the board and the PC (HyperTerminal software can be
used). Figure 4-1 shows the configuration for HyperTerminal software. After
communication is established, you can view the Linux directories using standard
Linux commands. Figure 4-2 illustrates the resulting display on the HyperTerminal.

Using an SD Card

If you have an SD Card with pictures or other multimedia content, you may use the
3-Stack Board to view its content.

To use the SD Card, follow these steps:

1. Insert the SD Card in the SD Card slot, which is located in the lower part of the
personality board, just below the USB connectors.

The system displays an SD card image in the left side of the display, and mounts the
card in the /mnt/mmcblk0p1 folder. If the mmcblk0p1 folder is not there, then the card
may not have the correct format. If so, then enter the following command:

mx31#fsdisk /dev/mmcblk

• For partition, use the n command.

• For type (extended or primary), use p for primary.

• Accept the default options provided by the prompt.

• To save the changes, apply w.
The SD card will now be mounted in /mnt.

2. Notice the multimedia file locations. By default, the mult imedia fi les are store d i n th e /
mnt/flc/directory. There are three folders: one for pictures, one for music and one for
video.

• mx31#cp /mnt/<sd_card/picture_file> /mnt/flc/Pictures

• mx31#cp /mnt/<sd_card/audio_file> /mnt/flc/Music

• mx31#cp /mnt/<sd_card/video_file> /mnt/flc/Video

3. Copy the content on the SD card to those folders, storing the picture files to the
Pictures folder, audio files to the Music folder, and video files to the Video folder.

The files are now visible to the multimedia applications.

Running the Applications

Using a USB Mass Storage Application

If the SD card is plugged and detected by the system, then you can run the USB Mass
Storage application, which allows the system to be seen by a PC as an ext ernal hard disk
driver that contains the content stored on the SD card.

This allows you to transfer information from the PC to the system and from the system to
the PC.

The information transferred from the PC to the system is stored on the SD card. You can
send multimedia files from the PC to the system, store them in the SD card, and then copy
them to the /mnt/flc directories

To use a USB mass storage application, follow these steps:

1. Make sure the SD card is plugged in and detected.

2. Connect a B-type to mini-AB cable from the USB mini-AB port (which is the OTG
port in the Personality board), to a USB port in the PC.

3. Select the Mass Storage mode.

4. Click on the Launch button.
The application is launched, and the PC wil l detect an external mass storage device.

Typically, the drive is seen as Drive F. Now the system ca n load information to this
drive as if it were a regular mass storage device.

After the files are stored in the SD card, repeat the steps in the previous section, Usin g
an SD Card, to make the files visible to the Multimedia applic ations.

Running the Applications

Now that the system contains the multimedia files, you can run the applications. First, see
