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 features an integrated USB-BDM debugger from P&E Microcomputer Systems.

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.

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.

7.1 Power Input

7.1.1 Power (PWR) Jack

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.
