TMS320F28377D: Parse Dwarf debugging information in COFF format .out files produced by CCS

Part Number: TMS320F28377D

Hi Team,

My customer need to statically parse the .out file and obtain the addresses of all global variable structures and their members.

CCS version is 8.3. .out file format is COFF.

Is there any tool or example code for parsing the Dwarf debugging information in the .out file?
The variable name and address need to be printed out.
The effect is as follows:

addr    size   symbol

    Hello -- there are some binary utilities included in the toolchain that you may want to explore.  The object file dump utility (ofd2000) will allow you to dump debug information and placement information that might be useful.  Also, the absolute lister may help you identify placement of structs and individual members (abs2000).  The object file dump utility has the ability to dump XML as well, which may improve parseability.  I would recommend looking through the C28x assembly tools manual at the relevant subchapters for more information about these.

    Of course, the linker map file will also show you placement information, but probably not as granular as you'd like (struct members).
