Hi,

{

int test1;

int test2;

}test_data =

Hi Rahul,

What is the development tool version you're using and what is the architecture ?

Have a great day,

Hi Rahul,

It seems you're using CW for HC12 v5.1.

The variables test1 and test2 are defined in the test_data structure.

The map file provide the info regarding the structure and not for the element contained in the structure.

In your case the info:

test_data

2100

1 .data

The structure is located at memory address 0x2100 and the size of 4 bytes is reserved for the element contained in the structure.

If we change int test1; by long test1 we will have:

test_data

2100

2 .data

Always same address but 4 bytes for test1 and 2 for test2.
