The header.h file contains the following line.



#define MEMORY_ADDRESS=0x80a800


Answer


1. Add -D (define) to the new value Within the project setting Preprocessor flags.



-D MEMORY_ADDRESS=0x40b620











2. Add a t the beginning of the Test Script (.ptu) the following's lines.


##include "header.h"
##undef MEMORY_ADDRESS
##include "header.h"




REMARK

This solution is possible only if you protect the header file. This means you code a #ifdef to avoid a double inclusion.
