Good question.
It seems the application is not compliant with the processor you're using.
If Multilink loader is saying:
Error while wrtting to C000..C200
information: No memory at the address
... it seems there is a problem with the application.
It's difficult to provide you more information.
This type of error is just saying your application contains some code at C000..C200 but there is no memory in your board/chip at this location.
By default the HC12 processor should have memory at this address.
It seems you've installed CodeWarrior development tool chain.
You're using another development to build your application and want to use Hiwave to debug it.
Do you have a problem with the Software or Hardware driver ?
Before to check with the project I recommend you to check with an example.
With the project wizard (File + New) you can create a project dedicated to your hardware configuration (processor and interface).
It's a right way to check if the tool is working fine.
Have a great day,
Pascal
