TMS320F280039: FLASH setup code to RAM module build fail

Part Number: TMS320F280039

Dear TI,

I am creating a new project.

And when I try to Copy time critical code and Flash setup code to RAM. When I build this project, it failed. And the failed infomation is above.

Building target: "New.out"
Invoking: C2000 Linker

I checked the cmd file F280039_flash_lnk.cmd as below.

   .TI.ramfunc      : LOAD = FLASH_BANK0_SEC1,
                      RUN = RAMLS0,
                      LOAD_START(RamfuncsLoadStart),
                      LOAD_SIZE(RamfuncsLoadSize),
                      LOAD_END(RamfuncsLoadEnd),
                      RUN_START(RamfuncsRunStart),
                      RUN_SIZE(RamfuncsRunSize),
                      RUN_END(RamfuncsRunEnd),
                      ALIGN(8)

And I check the code, there is EXTERNs in f28003x_globalprototypes.h

extern Uint16 RamfuncsLoadStart;
extern Uint16 RamfuncsLoadEnd;
extern Uint16 RamfuncsLoadSize;
extern Uint16 RamfuncsRunStart;
extern Uint16 RamfuncsRunEnd;
extern Uint16 RamfuncsRunSize;

This file is include in f28003x_examples.h, and f28003x_examples.h is included in the f28003x_sysctrl.c.

I also try add these EXTERNs in f28003x_sysctrl.c or main.c or where I using InitSysCtrl(), it stil can not be build success.

Please help me to solve these question.

Thank.
