FEE driver on TMS570LS3137

Other Parts Discussed in Thread: TMS570LS3137, HALCOGEN

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        
    }
  
};

               /* EEP number                            */     1U			   
        }
		,
		/* If project needs more than 16 blocks, add additional blocks here and also

/* 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?

A bit of further debugging!
After calling TI_Fee_WriteSync(), if I call TI_Fee_ErrorCode() I get a return value of Error_InvalidBlockIndex.
Not sure why I have an invalid block index?

Also, I've read through the PDFs, I can't find a description of the meaning of 'Number of DataSets', any ideas?

BR, Ian.

HI Ian,
Did you have a chance to use the HalCoGen example to get basic FEE to work? You can go to HalCoGen->Help->Help Topics->Examples->example_TI_Fee_Write_Read.c for a simple example. There is a also a wiki page at processors.wiki.ti.com/.../TI_FEE.

If you are not using FEE in Autosar context the data sets can be ignored. The TI_FEE_DATASELECT_BITS=0. The Data Set concept is described in 2.1.2.2 of the FEE userguide.

Looking at your code I can't really see anything wrong. You configure the same block size for both the blocks. If you write different data to the same block do you see the new data being written?

I will also forward you post to the FEE expert for further comment.

Hi Charles,
I haven't tried the HalCoGen example as-is, but my test code is just a copy and paste from the example.

My two blocks are different sizes, the #defines give a size of 104 bytes for block 1 and 24 bytes for block 2.
The only writes to the flash area are the virtual sector headers after running the init().
After the WriteSync() there is no more data written, there are no block headers at all.

I don't know if you've copied the wrong link for the wiki page, but I just get "There is currently no text in this page".

The only "Fee user guide" I can find is from this link: processors.wiki.ti.com/.../TI_FEE_User_Guide.pdf
But this is version 1.1 dated 11/12/2012, where can I find a more recent PDF?
Can you give me a link for this please?

Regards,
Ian.

Hi Ian,

Have you configured any data select bits in GUI?/What value do you see in "TI_FEE_DATASELECT_BITS" in ti_fee_cfg.h file? It should be 0.

Also, please be aware that TI_Fee_WriteSync API has a known bug. It writes data correctly but if it triggers a copy operation, it does not perform copy operation correctly. We already fixed this bug and will be releasing in HALCOGen release.

Hi Vishwanath,

I had 'dataselect bits' set to 8. I've changed to 0 and it now seems to be working. I have written blocks and read them back successfully.
Thanks for your help.

For the 'known bug' in WriteSync, can you supply a patch to use until the next HalCoGen release is available?

Regards,
Ian.

Hi Ian,

Attached is the file.

Also, please make sure you are calling TI_Fee_MainFunction(); periodically. This is because main function API takes care of copying of blocks to new sector and manages sector erasing.

TI_Fee_WriteSync(1, (uint8 *) &Params)

do

{

TI_Fee_MainFunction();

FeeStatus=TI_Fee_GetStatus(0);

}

while(FeeStatus!= IDLE);

Hi Vishwanath,

Thanks for the file.
I already have TI_Fee_MainFucntion() in my main loop, I also check for IDLE before initiating a write. But thanks for the pointer, that could have been easy to miss!

Thanks for your help.

Regards,
Ian.

Hi Ian,

I can see latest HALCoGen version is already available @ www.ti.com/.../halcogen

0 Ian Guffick over 9 years ago in reply to Vishwanath Reddy

Intellectual 350 points

Hi Vishwanath,

I'd checked on HalCoGen using the 'check for update', but it hasn't picked up the new version yet.
Thanks for the link, I'll download and install manually.

I also figured out that the link to the wiki page that Charles had sent has a trailing fullstop, if removed I get to the correct wiki page.

Regards,
Ian.

Hi Vishwanath,

There is a problem with the download. The page says it's version 04.06.00 5-Oct-2016, but the install contained in the ZIP file downloaded is 04.05.02 2-Mar-2016.

Regards,
Ian.

Hi Ian,

It may take some time to get the software updated in portal. You can use the patch file I sent till then.

Ok, thanks for your help.
