I was analyzing my program bin file to locate the Stack address, PC, Interrupts and Program code and the data section.

Everything looked sorted until interrupts, When it came to the  program code and Data section, i wasn't able to find two distinguished locations. Instead, the data section was merged up in between the program code. 

Can some one help me understand how i can trace out and distinguished the code section and .data section from my bin file?

    Use the Map file (linker listing) to see how memory has been used

    Thanks Neil.

    But my question was on identifying the sections in the bin file.

    Through my map file i understand the begin and end address of the data section(say 0x20000000 to 0x20000400 )

    and the code section.

    with reference to the snapshot of the bin file , i saw these addresses (

    0x20000000 to 0x20000400

    ) were scattered around instead of being bundled somewhere in the bin file.

    Please let me know your thoughts.

    That makes no sense!

    A bin file is just a byte-for-byte image - things cannot be 'scattered around' out of order!

    Are you sure you're not talking about a Hex ('Intel Hex', to be precise) file?

    Or some other format?
