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

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

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.

    Hi, 

    Looks like you are compiling it in COFF format. If so, please try updating the linker command file to have the following lines . 

    For the COFF , the symbols have a "_" prefix .
