Compiler/TMS320C6713: .hex file with memory MAP

kowalski

Part Number: TMS320C6713

Tool/software: TI C/C++ Compiler

Hi,

I am working on TMS320c6713, when i produce .hex file using C6000 hex utility in CCSv7, a linker map file is also created in the debug/release folder contain the detail address of different sections and their start address and length. As far as i know there is no such things as sections in Intex Hex file format (https://en.wikipedia.org/wiki/Intel_HEX), then how different sections given in linker map file is identified in hex file???

Thanks in advance...

Think about loading a binary executable file into system memory. After that load is complete, the organizing principle of the section is no longer present. It is the same thing with a hex file. Once the executable file is converted to the hex file, the sections are no longer present.

Thanks and regards,

Dear George Mock,

Can you explain a little bit, why exactly different sections are required in object file (.text, .data, .bss etc.). I know they help linker to combine different object file to create single executable, but is it necessary to combine different sections in same logical section even all that processor care about during execution are SEGMENTS not SECTIONS. Are the addresses are assigned to different instruction/variables during compile/link time????

This is really confusing...

It is true that the hardware doesn't care at all about program sections. Sections are a handy way for humans and linkers to think about how to organize a program. Please see processors.wiki.ti.com/.../A_Brief_History_of_TI_Object_File_Formats , as well as the description of object modules in chapter 2 of the Assembly Language Tools User's Guide: processors.wiki.ti.com/.../TI_Compiler_Information
