HOWTO get the size of code generated

claw — Sun, 11 Jun 2006 06:33:34 GMT

Working with CW 5.0, I've tried in vain to find the size of code generated.
Please, tell me where can I find this information.

Thanks in advance.

Which core are you using, a HC08?

For a HC08, check the map file, it is by default in the bin folder.

Is that unique to CW5? I don't see it with CW3.1. Maybe I'm just not setting an option the same way.

I always look at my listing file, and then check where things lie and how much room I have, since I may have things at fixed offsets and I need to be aware of not only what is where, but how I can 'expand' things without bumping into things that may be real bad!

Hi,

Its the same in 3.1 and 5.

I haven't done anything special to get it like this. Here is the last few lines from two different projects' map files.

Code:

CW3.1:*********************************************************************************************STATISTIC SECTION---------------------------------------------------------------------------------------------ExeFile:--------Number of blocks to be downloaded: 6Total size of all blocks to be downloaded: 2749CW5:*********************************************************************************************STATISTIC SECTION---------------------------------------------------------------------------------------------ExeFile:--------Number of blocks to be downloaded: 3Total size of all blocks to be downloaded: 226

Perhaps these lines from the end of the SECTION-ALLOCATION SECTION of the MAP-file are even more useful:

Code:

Summary of section sizes per section type:READ_ONLY (R):        FCA1 (dec:    64673)READ_WRITE (R/W):     1006 (dec:     4102)NO_INIT (N/I):         830 (dec:     2096)

I am having same problem in Metrowerks (not Freescale) Codewarrior Ver 7.3 for DSP56800. I cannot find the switch to set for listing output file at all. It is pretty important on the target which is a '8013 chip with only 16K of FLASH!!

Anyone come across that???

Thanks!!

Tim

Hello

Are you looking for a way to generate a map file in CodeWarrior for DSP568xx?

If you are building from the IDE:
    - Start IDE
    - Open the project
    - Open the Target Setting dialog (pressing ALT+F7)
    - Switch to "M56800E Linker" or "M56800 Linker" depending on the CPU you are targeting
    - Make sure "Generate Link Map File " is checked.

If you are building from command line make sure to link with option -Map.

I hope this helps.

Must be a 'C' issue. I see no option for a map file with assembler

Re: HOWTO get the size of code generated

Hello

MAP file is generated by the linker.

That means you should be able to get a MAP file for an ANSI C or relocatable assembler application.

Anything which gets through the linker to generate an executable file.

If you are using absolute assembly, you will not get any MAP file.

Basic idea is that programmer is controlling object allocation when programming in absolute assembly. So we suppose you know where you put your stuff.

You should be able to let the assembler generate a listing file though.

In HC08 V5.0 you have an assembly option -L for that. Please take also a look at option -Lasmc to configure whatever you want to see in the listing file.

There is a check box labeled "Generate Link Map" under "Linker", "M56800E Linker", and that is checked. There is no "*.map" file
generated however.

The only output file that is close is "sdm_pROM_xRAM.elf.xMAP" which is not at all like the HC05 map file I am used to seeing. There is no summary of memory used, no RAM used, are there even starting and ending addresses here??

Here is the listing (so you can see what I mean!!):

Hello

The .xMAP file is the file you have to look into.

At the end of the file you have a section Memory Map looking as follows:

# Memory map:
v_addr p_addr size name
00000000 00000000 000000A4 .p_interrupts_flash_ROM
000000A4 000000A4 000004FE .p_flash_ROM
000005A2 00000001 0000008D .p_flash_ROM_data
00020000 00020000 0000008B .p_boot_flash_ROM
0002F800 0002F800 00000800 .p_internal_RAM
00000001 00000001 000006B5 .x_internal_RAM
00001000 00001000 00000000 .x_flash_ROM
0000F000 0000F000 00001000 .x_onchip_peripherals
00FFFF00 00FFFF00 00000000 .x_EOnCE

This is where you find information around size of the application.

The MAP file is just a text file providing information on what happens during the link session. Format of this file is not standard and may vary from one CPU to the other.

I hope this helps.

I need only total size of code

PsychoDebugger — Tue, 20 Feb 2007 23:38:56 GMT

I need to know the code generated, because of my lecense.
I need only the total k, example 7k.
Do I have everytime to read the map file ad to sum all rows?
