Hello xinhua
For the hardware design of BDM interface, you may refer to the schematic of M5272 EVM board. The BDM interface design is on page 8:

In order to use Universal Multilink, you need to install CW7.2.1 and CW7.2.2 patches:
CodeWarrior Development Tools for ColdFire|NXP
And what is the OS on your PC? There is some problem to run CodeWarrior v7.2 on Windows 7-64bit OS or higher version. In addition, the firmware in your Universal Multilink may need to be reprogrammed in order to be supported by CodeWarrior v7.2.
