CCS/TMS320F28379D: "warning: creating output section "IQmath" without a SECTIONS specification" .

Part Number:TMS320F28379D

Tool/software: Code Composer Studio

I am trying to produce spwm waveform using epwmregs.

Epwm1interrupt  doesn't seem to be responding . I am not sure whether it is due to the IQmath section warning or the interrupts syntax is  wrong.

PFA the code below:

/**
* Generating 3 phase 50% duty cycle square wave
*/
#include "F28x_Project.h" // Device Header File and Examples Include File

#define MATH_TYPE 1
#include "IQmathLib.h"
static unsigned int index;
#pragma DATA_SECTION(sine_table, "IQmathTables");
_iq30 sine_table[512];

Please help me overcome this problem.

Thankyou.
