Debug Port Fail

Hi, is it possible to lock out debugger access after programming the DCF record in the UTEST memory region?


I am using the MPC5744P micro and the Lauterbach debugger. After programming a DCF record incorrectly, I am getting just a  "debug port fail' error without any additional error information when entering these commands: ‘SYStem.DETECT CPU’ or ‘SYStem.Up’. 


How do I go about unlocking the device?
