Hi,
The tiobj2bin,bat utility should invoke ofd hex6x.exe utility with the "-image" option (see TMS320C6000 Assembly Language Tools §10 and §11).
To investigate, could be usefull to look at the ofd output and the hex6x command files generated by the tiobj2bin, but these files are normally delete after completition of tiobj2bin.
You could edit the tiobj2bin.bat, remove the command delete of temp files, execute and look inside them.
Note that tiobj2bin commands ofd6.exe to generate and XML output. For humans, it is better to generate a plain text description (you can edit the .bat and adding a second invoktion of ofd ("%ofdcmd% ....") to generate it).
