Memory Errors MC9S12DG256 using CW

As per my previous posts I've been working on my own PCB board to autonomously control a dynamic suspension.  I've finally got the SPI interfaces to work (thanks everyone).  But after some modifications to the board I am recieving error messages that apparently render the board useless (the code doesn't upload).  They are:

FP: FLASH_4000 flash module is bad or protected.
FP: FLASH_C000 flash module is bad or protected.

I've tried unsecuring to no avail.  Any ideas?

TIA,

Mark

As the error messages state, you've got a problem when trying to write to Flash memory. If you were writing and storing to Flash memory prior to your modifications, then whatever you changed on the board has affected Flash memory, Check the addressing lines, and whether or not you've got sufficient voltage to program Flash.
