hello, I have some problems about how to configure the .lcf file in codewarrior 10.7, bellow is the memmap.h file and MPC5604B_FLASH.lcf file. 

Can you help me to modified the MPC5604B_FLASH.lcf file according to the memmap.h file ?

When I configured ,it encounter many mistakes.

Thank you very much.
