i.MX28 EVK

Multimedia and connectivity

The i.MX28 EVK is designed for

multimedia and connectivity applications.

These applications use the i.MX28 series

ARM9™ applications processor. The

i.MX28 EVK can be used as a hardware

and software development platform. This

decreases time to market and provides a

near-to-final product design. The board

support package (BSP) for the i.MX28

EVK contains drivers optimized for

multimedia operations using the i.MX28.

The following features are available

in the i.MX28 EVK board:

• i.MX28processor

• DoubleDataRate2(DDR2)

DRAMmemory

• DualUSBconnections

• Two10/100Ethernetconnections

• TwoSecureDigital(SD)/multimedia

card (MMC) connections

• Twoapplicationuniversalasynchronous

• OneconsoleUART

• Twocontrollerareanetworks(CANs)

• AudioI/Ojacks

Getting Started

This section describes how to use the i.MX28 Kit EVK and the

components in the EVK. This section also describes the PC requirements

to develop applications using the i.MX28 EVK.

Unpacking the Kit

The i.MX28 EVK is shipped with

the items listed in Table 1.

Ensure the items listed in Table 1 are

available in the i.MX28 development

kit. Remove the EVK board from the

antistatic bag and perform a visual

inspection.

Note:TheLCDModuleisanoptionaladd-onmodule

andisorderedseparately,MCIMX28LCD.

LCD Board Assembly

Connecting the LCD board to the i.MX28 EVK board

NOTE:

The4.3”widescreenvideographicsarray(WVGA)LCD

board is an optional card for the i.MX28 EVK board and

it is sold separately from the i.MX28 EVK board.

The i.MX28 EVK board is

connected to the add-on

LCDboardusing120-pin

surface mount connectors.

The connectors are

keyed to avoid incorrect

connection. Therefore,

there is only one way to

connect the boards. The

LCDboardisconnected

to the J78 connector. The

J78 connector is located

on the top of the i.MX28

EVK board as shown.
