I have a TMDSSOLARUINVKIT, and i try to add SFRA without GUI to project. but i have a problem

**** Build Finished ****
When, I add SFRA code from www.ti.com/lit/ug/spruhz5a/spruhz5a.pdf in chapter 3.4
1. #include "SFRA_IQ_Include.h" on SolarMicroInv-Main.c of SolarMicroInv_F2803x file
1.2 Add Link SFRA Library: (SFRA_IQ_Lib.lib) to the project, SFRA lib is located at :
controlSUITE\development\libs\app_libs\SFRA\include
1.3 Add Link Part of C2000 linker : (SFRA_IQ_Lib.lib) by SFRA lib is located at :
..\controlSUITE\development\libs\app_libs\SFRA\v1_10_00_00\SFRA_IQ\lib
1.4 Add Link Part of C2000 linker : (rts2800_ml.lib) by SFRA lib is located at :
..\controlSUITE\libs\utilities\flash_api\2803x\v100\lib\rts2800_ml.lib
2. Create and add module structure in SolarMicroInv-Main.c of SolarMicroInv_F2803x file
#define SFRA_ISR_FREQ 200000
#define SFRA_FREQ_START 100
#define SFRA_FREQ_LENGTH 100
//SFRA step Multiply = 10^(1/No of steps per decade(40))
#define FREQ_STEP_MULTIPLY (float)1.059253
3.Declare Arrays for FRA Data Storage in SolarMicroInv-Main.c
// SFRA lib Object
SFRA_IQ SFRA1;
// SFRA Variables
int32 Plant_MagVect[SFRA_FREQ_LENGTH];
int32 Plant_PhaseVect[SFRA_FREQ_LENGTH];
int32 OL_MagVect[SFRA_FREQ_LENGTH];
int32 OL_PhaseVect[SFRA_FREQ_LENGTH];
float32 FreqVect[SFRA_FREQ_LENGTH];
//Flag for reinitializing SFRA variables
int16 initializationFlag;
//extern to access tables in ROM
extern long IQsinTable[];
4. Initializing the module in SolarMicroInv-Main.c
// Do SFRA Object Initialization here
//SFRA Object Initialization
//Specify the injection amplitude
SFRA1.amplitude=_IQ26(0.01);
//Specify the length of SFRA
SFRA1.Vec_Length=SFRA_FREQ_LENGTH;
//Specify the SFRA ISR Frequency
SFRA1.ISR_Freq=SFRA_ISR_FREQ;
//Specify the Start Frequency of the SFRA analysis
SFRA1.Freq_Start=SFRA_FREQ_START;
//Specify the Frequency Step
SFRA1.Freq_Step=FREQ_STEP_MULTIPLY;
//Assign array location to Pointers in the SFRA object
SFRA1.FreqVect=FreqVect;
SFRA1.GH_MagVect=OL_MagVect;
SFRA1.GH_PhaseVect=OL_PhaseVect;
SFRA1.H_MagVect=Plant_MagVect;
SFRA1.H_PhaseVect=Plant_PhaseVect;
initializationFlag = 0;
/**** TEST: Attempt to cause initialization of SFRA_IQ before sweep ****/
SFRA_IQ_INIT(&SFRA1);
5. Using the module
if(CloseIloopInv==1)
{
cntlPI_BusInv.Ref =Bus_Volt_notch.Out;
cntlPI_BusInv.Fbk =inv_bus_ref;
CNTL_PI_IQ_MACRO(cntlPI_BusInv)
inv_Iset=cntlPI_BusInv.Out;
inv_ref_cur_inst = _IQ24mpy(inv_Iset, InvSine);
cntl3p3z_InvI_vars.Ref=SFRA_IQ_INJECT(inv_ref_cur_inst);
cntl3p3z_InvI_vars.Fdbk=inv_meas_cur_inst;
CNTL_3P3Z_IQ_ASM(&cntl3p3z_InvI_coeff,&cntl3p3z_InvI_vars);
duty_inv_pu=_IQ24div((cntl3p3z_InvI_vars.Out+inv_meas_vol_inst),vbus_meas_inst);
duty_inv_pu= (duty_inv_pu>_IQ24(1.0))?_IQ24(1.0):duty_inv_pu;
duty_inv_pu= (duty_inv_pu<_IQ24(-1.0))?_IQ24(-1.0):duty_inv_pu;
SFRA_IQ_COLLECT(&cntl3p3z_InvI_vars.Out,&cntl3p3z_InvI_vars.Fdbk);
}
#endif // (INCR_BUILD == 3)
6.Background Task: Call the background function in a slow task:
void A1(void)
