CCS / TMS320C6678：Error loading gel file

Part Number: TMS320C6678

Tool/software: Code Composer Studio

Hello!
When using 6678, I encountered the following problem. If I don't load the gel file and directly simulate it, I can't run to the main function.
When loading ti to provide the gel of the evm board, the prompt:

IcePick_D: GEL: Error while executing OnTargetConnect(): identifier not found: DNUM at GEL_TextOut("DSP core #%d\n", 0, 1, 0, 0, DNUM) [evmc6678l-gel-evmc6678l.gel:1782] at Core_Info() [evmc6678l-gel-evmc6678l.gel:438] at OnTargetConnect() .

And still can't enter the main function。
