stellaris LM3S8962 how to find the my entire source code size???

Hi,
I moved your post from the MSP430 forum to the TM4C forum where you should be able to receive support.

Hello Kavisaran,

You may want to dump the content of the flash into a bin file and use a bin count utility to get the size. Note that if there are empty flash location in between programmed words, it will be counted as valid program location.

Hello f.m.

Thanks for correcting me. I read it the other way...

Regards
Amit

And if you want the size of the source code (the question asked) rather than the binary (the question inferred) the simplest way on windows may be to copy the source to a separate directory and use the directory properties to find the size. I suggest copy just as the simplest way to filter out non source files.

I suspect the question already answered is the one you meant to ask though.

I suspect the question already answered is the one you meant to ask though.

Quite correct. Reading and understanding post here is often troublesome. A little more thought/carefulness on the enquirer's side would be helpful. And I restrain myself from interpreting the lack of those ...

hello Robert,

coping only source code to the another folder and by checking its property i get the size of the entire file not the size of source code, for your information file size includes everything like comments etc.. but source code size is optimized during compilation it removes comments etc and size will be decreased, so the file size and source code size after compilation is totally different, so your answer is wrong.

someone please help me with below questions.

i want to know the source code size after optimization or after dumping the source code into the board, to be precise want to know how many bytes has been dumped into flash ROM, between in .map file i get information about ram and rom, but am confused with 2 things in the .map below is the part of info from my map file,
7432 bytes of readonly code memory
1592 bytes of readonly data memory
692 bytes of readwrite data memory

now my question is
1) what is the difference btw readonly code memory and readonly data memory?????

2) during dumping the code to the board i get another info in the debug window as "9024 bytes downloaded and verified"

3) now for example if people say "7432 bytes of readonly code memory" is my source code size as per the .map file??? then what is this "9024 bytes downloaded and verified" which i get after dumping code to the board from the debug window????? and what is this "1,592 bytes of readonly data memory"

4) from above observation which is the source code size??? and which is rom size?? and what is that info i got in debug window????

please answer all the 4 questions one by one, for better clarity

The term "readonly memory" refers to Flash.

"code memory", as one might guess, are the Flash size occupied by actual routines/instructions, i.e. "code".

And "readonly data" are constant data, which are also located in Flash to save precious RAM space. Think of constant arrays and strings that never change during runtime.

"readwrite data" is the size of RAM occupied/used by your application. Since it is generated at runtime, and lost when powering off the MCU, there is nothing to "download" into RAM. Only the Flash (code and constant data) is downloaded and "flashed" to the (not so) read-only memory by the debugger or download tool.

This whole procedure is slightly different from a PC, where everything is actually RAM, and all addresses are virtual. To understand the whole process, I suggest to search for documents about the linking stage of C compilers/toolchains in general, and for Cortex M controllers in particular. The Cortex M has a fixed memory map, and somehow the linker must map logical addresses (function names and variable names) to real addresses. The map file is a list of this mapping, and the part you cited is just the summary (memory occupation).

this is my entire map file, btw still and not conviced with the answer, u mean to say read only code + ready only data is my entire source code size???

Sorry, but I don't have the time for a lengthy linie-by-line explanation of the map file.

I'm not a TI employee, and don't get paid for the time I spend on this forum.

this is my entire map file, btw still and not conviced with the answer, u mean to say read only code + ready only data is my entire source code size???

Almost

The flash will contain the following

• Executable code that is run from flash
• Constant data
• compiler overhead (Ie if it has to generate constants for some reason)
• Initialization tables (for initial values assigned to modifiable variables)
• If you run some code from ram, then the flash will also keep a copy of that.

Like f.m., I'm not going to read through a map file. Is there some reason you think the above does not account for the usage?

Robert 

May I note that both posters f.m. & Robert are "pros" - generously provide much time/effort here in support of others - too often unthanked.   

I take this opportunity to thank, "f.m. and Robert."  

Indeed the map file you present is large, long and forbidding.   (that's a normal, human reaction - is it not?)

Might I suggest your creation of a far smaller, simpler program - designed expressly to, "Answer your file size questions."   Limiting the size will (greatly) ease the analysis efforts demanded/expended - both by you and your forum "helpers."   In addition - as f.m. has detailed - you can experiment by adding a known number of constants and arrays - and then discover, "Where & how" they're stored.

KISS is a (too little) byword practiced here.   (Vendor will not touch w/proverbial "ten foot pole.")   Yet if my suggestion has merit - it is the "Unlocking of Understanding via the creation of a vastly more manageable (battlefield)" - aka KISS.  You will not be disappointed...
