ccs4 map file

Usually into the .map file it's possible to find information about  <code lenght> (flash bytes), <constant> (flash bytes and <memory lenght> (ram bytes).

Were can I find this information for CodeComposerStutio4 (inside .map file there aren't !! ) ?

For IAR compiler this informations are at the end of the .map file.

    Hi Maurizio,

    the information you're looking for are in the 'Memory Configuration' table of your map file. Pls refer to the example below:

    Read the table as follows:

    origin: start of the segment
    length: lenght of the segment (in HEX values)
    used: amount of memory in the segment used (in HEX values)
    unused: free memory in the segment (in HEX values).

    So here's the example for RAM:

    starts at 0x0214, is 0x03e8 = 1000bytes large, of which 0x0143 = 323bytes were used and 0x02a5 = 677bytes are free.

    P.S. When you start debugging your project you will see the total amount of flash and const memory in the console window.

    Thanks.

    I was accustomed to a more direct indication: into IAR map file this data are at the end of the file, directly in BYTES.
