TMS320F280023: The format of Vector CANape

Part Number: TMS320F280023

Tool/software:

Hi, 

I am currently evaluating TMS320F280023, which integrates the code of the CCP calibration protocol, and encountered the problem that the elf file is not recognized.
Is it recommended to use elf or out format in Vector CANape?
Why can the CCS debugger see the symbol (which supports observed variables, breakpoints, etc.) but not in CANape?

Are the configurations in the two diagrams below related? 

Thanks a lot! 

Andy
