2 Getting Started

To get started, please refer to the M5211 Quick Start Guide included with this development kit.

The M5211DEMO single board computer is a fully assembled, fully functional development board for the

Freescale MCF5211 microcontroller. An included serial cable, USB cable, and support software allows

you to get started quickly.

The purpose of this development board is to assist you in quickly developing an application in a known

working environment, to provide an evaluation platform, or as a control module for an embedded system.

You should be familiar with memory mapping, memory types, and embedded software design for

successful application development.

You should be familiar with the hardware and software operation of the target MCF5211 device before

beginning. If necessary, refer to the MCF5213 Integrated Microcontroller Reference Manual, included on

the support CD, for details on the operation of the MCF5211.

3 Software Development

Software development requires the use of a ColdFire assembler or compiler and a host PC running a

ColdFire BDM interface. CodeWarrior 6.1 Special Edition, which is supplied with this board, allows you

to develop and debug application code and to program the flash memory.

To ensure successful application development, load and execute the application from RAM. After the

application has been completely debugged fully functional, it can be ported to flash memory. When

programmed into flash memory, the application will execute from power-on or RESET.

4 Operating Modes

TheM5211DEMOboardoperatesintwobasicmodesRUNmode, or DEBUG mode. RUN mode executes

user application code from power-on or reset. DEBUG mode supports the development and debug of

applications via the integrated USB BDM. An optional BDM_PORT is provided but not installed. See

the related sections below for quickly starting the board in the desired mode of operation.

The board has been preloaded with a demonstration program that operates in the RUN mode (see the

M5211DEMO Quick Start Guide for additional information). The VDD LED is lit when power is applied

to the board and the PWR_SEL option header is set correctly. The OFF/ON switch must also be set to the

ON position.

4.1 RUN Mode

RUN mode allows your application to execute out of flash memory when power is applied to the board or

the RESET button is pressed. Use these settings to configure the M5211DEMO board for RUN mode

using the USB bus to power the board. See tSection 7, “Power,” for details on configuring the board for

alternate power input.

1. Connect a serial cable between the board and a host PC if needed.

2. Connect auxiliary equipment to board if needed.

3. Configure the board option jumpers as shown in Table 2.

will begin to execute.

4.2 DEBUG Mode

DEBUG mode supports application development and debug using the ColdFire background debug mode

(BDM). Background mode is accessible using either the integrated USB-BDM or an external ColdFire

BDM cable. Use of the integrated BDM requires a host PC with an available USB port and an A/B USB

cable and appropriate hosting software. The USB cable used must be USB 2.0 compliant. A 26-pin

BDM_PORT header supports the use of an external BDM cable. This header is not installed in default

configurations. The steps describe using the integrated USB-BDM. See Section 7, “Power,” for details

on configuring the board for alternate power input.

1. Connect a serial cable between the board and a host PC if needed.

2. Connect auxiliary equipment to board if needed.

3. Install and launch CodeWarrior™6.1 Special Edition, or other software capable of communicating

with the ColdFire MCU.

4. Configure the board option jumpers as shown in Table 3.

Connect the supplied USB cable between an available USB port on the host PC and the USB connector on

the board.

Hosting development software will establish background communication.

6 Development Support

Application development and debug for the target MCF5211 is supported through the BDM interface. The

debug interface consists of an integrated USB-BDM debugger and an optional 26-pin header

(BDM_PORT). The BDM_PORT header is not installed in default configuration, but you may install it if

needed.

6.1 Integrated BDM_PORT

The M5211DEMO board featuresan integratedUSB-BDMdebuggerfromP&EMicrocomputerSystems.

The integrated debugger supports application development and debugging via the background debug

mode. A USB, type B, connector provides connectivity between the target board to the host PC.

The integrated debugger provides power and ground to the target, thereby eliminating the need to power

the board externally. When used, power from the USB-BDM circuit is derived from the USB bus and total

current consumption is limited by the USB specification. Total current consumption for the target board,

and all connected circuitry, must not exceed 500 mA. Excessive current drain will violate the USB

specification causing the bus to disconnect. This forces a target POR.

CAUTION

Violating the USB specification will cause the USB bus to disconnect

forcing the target to reset.

Use of the integrated USB BDM requires the use of CodeWarrior 6.1 Special Edition or development tools

from P&E Microcomputer Systems.

6.2 BDM_PORT Header

A ColdFire BDM cable may be attached to the 26-pin BDM_PORT port header. This header is not

installed in default configuration and its use requires you to install a 2x13, 0.1" center, BERG header.

Refer to the BDM documentation in the MCF5213 User's Manual for details on the use of the BDM cable.

The BDM_PORT header pin-out is shown in Figure 2.

Power

Freescale Semiconductor8

7Power

The M5211DEMO is designed to be powered from the USB_BDM during application development. A

2.0 mm barrel connector and a two-position, screw-type, terminal block (BATT) has been applied to

support stand-alone operation. Additionally, the board may be powered through connector J1. The board

may also be configured to supply power through connector J1 to external circuitry. An OFF/ON switch

allows you to quickly and easily turn the board on and off.

When using the integrated USB-BDM, the board draws power from the USB bus. Excessive current drain

will violate the USB specification causing the USB bus to disconnect forcing a POR. Total current

consumption of the board and connected circuitry, therefore, must be limited to less than 500 mA.

CAUTION

Violating the USB specification will cause the USB bus to disconnect. This

will force a hard reset on the target.

The installed barrel connector accepts a center-positive, 2.1 mm barrel plug. The terminal block accepts

wire sizes ranging from 28 ga to 16 ga. Voltage input must be in the range between +5 V and +20 V. At

no time should input voltage exceed +20 V as damage to the board may result. The terminal block input

is connected directly to the upper voltage rail. Input protection is not applied on this voltage input.

Exercise caution when using the terminal block to input power to the board.

Voltage supplied through connector J1 is also connected directly to the board voltage rails. No protection

is applied on this input and you must exercise caution when powering the board from connector J1.

CAUTION

Input protection is not applied to the J1 or BATT power inputs. Excessive

input voltage or current will damage the board.

The PWR power jack, shown in Figure 3, consists of a 2.1 mm, center-positive, barrel connector. Voltage

applied at this connector should range between +5 V and +20 V.

Figure 3. PWR Jack

7.1.2 Terminal (BATT) Block

The BATT terminal block, shown in Figure 4, is a 3.5 mm, screw-type terminal block connected directly

to the VDD voltage rail. Caution must be used when using this input since input protection is not applied.

Use of this input requires a regulated +3.3 V voltage source.

Figure 4. BATT Terminal Block

7.1.3 Connector J1

See the schematic for details on using this connection to supply power to the board or source power from

the board. Use of this input requires a regulated +3.3 V voltage source.

CAUTION

Do not overdrive the J1 or BATT inputs as damage to the board may result.

7.2 VDD LED

The VDD LED indicates the state of power applied to the development board. This LED is on when power

is applied to the board. If no power is applied or the OFF/ON switch is in the OFF position, this LED be

off. The VDD LED is located after the OFF/ON switch and will indicate the state of the switch if the board

is powered from the on-board regulator, the USB circuit, or the BATT terminal block input.

7.3 Power (OFF/ON) Switch

The OFF/ON switch, shown in Figure 5, connects and disconnects all input voltage sources to the board.

In the OFF position, the board is unpowered and no voltage is present on the upper voltage rail. In the ON

position, the input voltage source is connected to the upper voltage rail.

Figure 5. OFF/ON Switch

7.4 Power Select

Configuration of applied input power is controlled using two option headers. The PWR_SEL header

selects between the on-board voltage regulator and the USB voltage input. The VX_EN header connects

J1-1 directly to the upper voltage rail. The illustrations below show the different configuration for each

option header.

7.4.1 PWR_SEL

Figure 6 shows the PWR_SEL header.

Figure 6. PWR_SEL Option Header

Power from the integrated BDM is drawn from the USB bus and is limited to 500 mA. Excessive current

drain will violate the USB specification causing the USB bus to disconnect.

CAUTION

Violating the USB specification will cause the USB bus to disconnect. This

will cause the board to reset.

The on-board voltage regulator (VR1) accepts power input through a 2.1 mm barrel connector (PWR).

Input voltage may range from +5 V to +20 V. VR1 provides a +3.3 V fixed output limited to 800 mA.

Over-temperature and over-current limit built into the voltage regulator provides limited protection from

damage due to excessive stresses.
