IAR Map file Interpretation

Seng Kee Tan

Hi,

I am having strange issue in my code.

Even though I can compile successfully under IAR and downloaded to the MSP430 to run, I have faces some starne problem. The code works on MSP with 2K RAM.

Hence, I would like to know is there any document available to understand the map file generated?

I am interested in the meaning of "MODULE SUMMARY" section with columns of "Module CODE DATA CONST".

Also, the " CALL GRAPH" section that talks abt the actual stack used?

Thank you.

A good resource to find this information will be the C compiler's reference guide found under the IAR help menu.

You can see the section on placing code and data and also get info about stack usage from that guide.

Hi,

Thanks.

In the map file, there are DATA memory (+xx absolute) and CONST memory. During runtime, the CONSTANT memory and (+xx absolute) memory will not occupied the stack right? As I see that both are allocated to the Flash and Periphrals memory.

Thank you.

CONSTANT & DATA should not affect the stack. Stack is affected by RAM content.
