Hi,
What version of Windows are you using? For Windows 7 and later, the recommended version of CodeWarrior is v11.1.
What is the part number of the MCU you are trying to program? Also, for which MCU was the project originally created?
Depending on the amount of memory the device has, certain memory sections may be reserved or unimplemented. I recommend checking the device’s memory map to confirm.
Best Regards,
Pablo
