TMS570LS0432: Cannot write/read from flash (Newbie)

Hello all,

As a graduate engineer who is newbie in embedded world,  the embedded project i am working on requires me to write a variable to the flash and use it when power cut off and comes back again. I am trying to get the fee example in HALCoGeN to work but no luck till now. I am watching the expressions from example code like "SpecialRamBlock[0]" and "oResult" if "BlockNumber" 1 is written to them or can be read from them but i don't see anything changes in debug. I left my HALCoGeN configuration default as instructed in example and i am using the example code just the way it is.

Example code:

#include "ti_fee.h"
/* USER CODE END */

/* Include Files */
#include "sys_common.h"
/* USER CODE BEGIN (1) */


uint16 u16JobResult,Status;
Std_ReturnType oResult=E_OK;
unsigned char read_data[100]={0};

uint8 SpecialRamBlock[100];

unsigned char pattern;
uint16 u16writecounter;

unsigned int  FeeVirtualSectorNumber;
unsigned char VsState, u8EEPIndex;
unsigned char u8VirtualSector;
uint8 Test_Recovery;
uint8 Test_Cancel;

void delay(void)
{
    unsigned int dummycnt=0x0000FFU;
    do
    {
        dummycnt--;
    }
    while(dummycnt>0);
}
/* USER CODE END */

/* USER CODE BEGIN (2) */
/* USER CODE END */

void main(void)
{
/* USER CODE BEGIN (3) */
    unsigned int BlockNumber;
    unsigned int BlockOffset, Length;
    unsigned char *Read_Ptr=read_data;

    unsigned int loop;
    
    /* Initialize RAM array.*/
    for(loop=0;loop<100;loop++)SpecialRamBlock[loop] = loop;

    /* Initialize FEE. This will create Virtual sectors, initialize global variables etc.*/
    TI_Fee_Init();
    do
    {
        TI_Fee_MainFunction();
        delay();
        Status=TI_Fee_GetStatus(0 );
    }
    while(Status!= IDLE);

    /* Write the block into EEP Asynchronously. Block size is configured in ti_fee_cfg.c file. Default Block size is 
       8 bytes */
    BlockNumber=0x1;
    TI_Fee_WriteAsync(BlockNumber, &SpecialRamBlock[0]);
    do
    {
        TI_Fee_MainFunction();
        delay();
        Status=TI_Fee_GetStatus(0);
    }
    while(Status!=IDLE);

    /* Write the block into EEP Synchronously. Write will not happen since data is same. */
    TI_Fee_WriteSync(BlockNumber, &SpecialRamBlock[0]);

    /* Read the block with unknown length */
     BlockOffset = 0;
     Length = 0xFFFF;
     oResult=TI_Fee_Read(BlockNumber,BlockOffset,Read_Ptr,Length);
     do
     {
         TI_Fee_MainFunction();
         delay();
         Status=TI_Fee_GetStatus(0);
     }
    while(Status!=IDLE);

    /* Invalidate a written block  */
    TI_Fee_InvalidateBlock(BlockNumber);
    do
    {
        TI_Fee_MainFunction();
        delay();
        Status=TI_Fee_GetStatus(0);
    }
    while(Status!=IDLE);

    /* Format bank 7 */
    TI_Fee_Format(0xA5A5A5A5U);

    while(1);

Default HALCoGeN configuration..

I believe i have linked F021 flash API and included the F021 headers..

Can you help me out in this seemingly simple matter ? What do i miss out ? Thanks in advance..
