MCF5213 EzPort Question

All,
 
I have been working on the EzPort for the past few days and only have a few lingering issues.  Take these two scenarios as an example.
1) The target MCF5213 coldfire has an image burned in.  In this case, I can read data, erase the data, and write new data without any issues.
 
2.) In this case, the target MCF5213 coldfire has not image (the image was erased with a P&E BDM).  In this case, I cannot write any data to the flash.  Using a scope, I can confirm the commands are reaching the target correctly and are identical to the first scenario.  Since there is no data to read, I cannot say whether the read and erase commands work either.
 
Has anyone encounter this issue?  The Status Register indicates the Configuration Register has been loaded and no errors have been detected.  Since the settings and commands have not changed, I am at a loss to understand what is happening.  Thank you for any help/assistance you can provide.
