FEE driver on TMS570LS3137

Hi All,

I'm trying to use the FEE driver with a TMS570LS3137.

I call TI_Fee_Init() and can see that the Flash memory at 0xF0200000 has been initialised with the correct headers, but doing a TI_Fee_WriteSync() doesn't seem to add any blocks.

In the init of my main I have:

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

Then in my main loop I have:

		TI_Fee_MainFunction();
		FeeStatus=TI_Fee_GetStatus(0);
		if((FeeStatus == IDLE) && (CtrlParams.FlashEEControl == 1))
		{
			/* Write the block into EEP Synchronously. Write will not happen if data is same. */
			TI_Fee_WriteSync(1, (uint8 *) &Params);
			CtrlParams.FlashEEControl = 2;
		}
		FeeStatus=TI_Fee_GetStatus(0);
		if((FeeStatus == IDLE) && (CtrlParams.FlashEEControl == 2))
		{
			/* Write the block into EEP Synchronously. Write will not happen if data is same. */
			TI_Fee_WriteSync(2, (uint8 *) &CtrlParams);
			CtrlParams.FlashEEControl = 3;
		}

My virtual sector and block configuration in ti_fee_cfg.c is:

const Fee_VirtualSectorConfigType Fee_VirtualSectorConfiguration[TI_FEE_NUMBER_OF_VIRTUAL_SECTORS] =
{

    /* Virtual Sector 1 */
    {
       /* Virtual sector number */      1U,
       /* Bank                  */      7U,      
       /* Start Sector          */      (Fapi_FlashSectorType)0U,
       /* End Sector            */      (Fapi_FlashSectorType)0U
    },
    /* Virtual Sector 2 */
    {
        /* Virtual sector number */     2U,
        /* Bank                  */     7U,
        /* Start Sector          */     (Fapi_FlashSectorType)1U,            
		/* End Sector            */     (Fapi_FlashSectorType)1U
    }
    ,
    /* Virtual Sector 3 */
    {
        /* Virtual sector number */     3U,
        /* Bank                  */     7U,     
        /* Start Sector          */     (Fapi_FlashSectorType)2U,
        /* End Sector            */     (Fapi_FlashSectorType)2U     
    }
    ,
    /* Virtual Sector 4 */
    {
        /* Virtual sector number */     4U,
        /* Bank                  */     7U,
        /* Start Sector          */     (Fapi_FlashSectorType)3U,
        /* End Sector            */     (Fapi_FlashSectorType)3U        
    }
  
};

        }
		,

/* USER CODE BEGIN (1) */
/* USER CODE END */
 
};

Should this work, or am I setting something up incorrectly?

There seems to be confusing use of EEP numbers of 0/1 and 1/2 in the sample code and documents.

Can anyone offer any pointers?
