The forum nice to ask some questions but if you do not get answers you should ask your distributor they shoud be able to give you all the answers
Here is the answer for this question:
The amount of the RAM and ROM used by the Open AT application can be found from the â€œmâ€ file found in the projectâ€™s â€œgcc/outâ€ folder. In the â€œmâ€ file under the heading â€œLinker script and memory mapâ€ the total size of ROM used by the Open AT application is indicated at the start of the â€œ.textâ€ section.
The size of RAM used is the sum of the size of RAM used for initialized data, uninitialized data and common data segments. The size of RAM used for initialized data is indicated at the start of the â€œ.dataâ€ section. The size of RAM used by initialized data and common data is shown at the start of the â€œ.bssâ€ section. In the attached â€œmâ€ file you can find our comments by searching for the string â€œATSUP1496â€.
In the attached â€œmâ€ file,
ROM used by the Open AT Application = 0x2297c = 141692 bytes
RAM used by the Open AT Application = 0xf30 + 0x3c20 = 0x4b50 = 19280 bytes
The â€œarm-elf-size.exeâ€ tool returns the size of the â€œ.elfâ€ file and the size of the various segments of the file that is given as an argument. In the screen shot the â€œgcc_SMS_App_32.elfâ€ file consists of 140108 bytes of text, 3884 bytes of initialized data and 39808 bytes of uninitialized data and stack. The last two columns are the total size of the file in decimal and hexadecimal format. Hence, this tool can also be used to obtain the size of RAM and ROM used by the Open AT application. The text size returned by this tool corresponds to the ROM used by the application. The sum of â€œdataâ€ and â€œbssâ€ sizes corresponds to the RAM used by the Open AT application.
I hope this is helpfull
