    Is the project you are building actually compiling the C source files that contain these labels?

    For instance, the _ConfigCpuTimer, _CpuTimer0 and _InitCpuTimers are defined in <CONTROLSUITE_INSTALL_DIR>\device_support\f2833x\v132\DSP2833x_common\source\DSP2833x_CpuTimers.c

    The _InitPieCtrl is in <CONTROLSUITE_INSTALL_DIR>\device_support\f2833x\v132\DSP2833x_common\source\DSP2833x_PieCtrl.c
    The _initPieVectTable is in <CONTROLSUITE_INSTALL_DIR>\device_support\f2833x\v132\DSP2833x_common\source\DSP2833x_PieVect.c

    You need to make sure these are in your project and compiled accordingly.
