I'm assuming you're using codewarrior?

 

To burn the flash chip you actually need RAM available on the board. This is typically DDR. So, before you try and program flash work on getting your DDR up and running correctly. 

 

You can enter in settings for your particular DDR in the cfg file for codewarrior. You can then use the Hardware Diagnostics to test your DDR. This will run extensive memory tests on it.

 

 

Once you have DDR working, you need to tell the flash programmer where to find free buffer space - this is where you should put your DDR base address.
