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.

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.
