How to define symbol for linker file (.ld) ?

[Waszniowski]

Hallo all,

 

I am using VisualGDB for ARM embedded project. I have a problem to define a symbol for linker file.

I have the following line in my .ld file:

M_VECTOR_RAM_SIZE = DEFINED(__flash_vector_table__) ? 0x0 : 0x0400;

 

I need to define __flash_vector_table__ to be evaluated by linker to set M_VECTOR_RAM_SIZE = 0x0.

I tried to define it in main.c

#define __flash_vector_table__

I tried to define it in VisualGDB project properties and also in Visual Studio properties.

 

But the generated map file still shows

0x00000400                M_VECTOR_RAM_SIZE = DEFINED (__flash_vector_table__)?0x0:0x400

It means that the symbol __flash_vector_table__ was not defined during linking.

 

Please can anybody help me to define symbol to be considered in .ld file??

 

Thanks,

Libor
