Question: Error Message : " Invalid Object file " when trying to load my program ?

Answer: The linker is producing an executable with the TI new COFF format (default in current revisions is COFF2). Some TI emulators and simulators do not understand this new format and can only treat these files as invalid objects.
A workaround is to link with the " -v0 " option to use the old COFF format. Another solution is to use the latest emulator or simulator releases which support the new COFF format.
