My CableCF or CableCFLV parallel port ColdFire programmer isn't working. What should I do?
If your CableCF and CableCFLV worked in the past and you recently changed computers, you should read FAQ#4 which deals with parallel port issues.

The technical summary attached below details what pins the interfaces must drive on the debug header to force the ColdFire device into debug mode.
