TMS320F28377S: Fapi_issueProgrammingCommand program one word at the time

Hi Vamsi,

Ok, thanks I redesigned my data FIFO that the data is 128 bit aligned. But still I have problems programming the flash.

 program  size=1024 words at the time.

address = 0xc2000

Data is not 0XFFFF. I checked that.

Flash is erased.

My program runs in bank0

This is the relevant code:

    EALLOW;
    Flash_CfgBank1 ();  // init the flash programming process

    for(i=0;i<size;i+=8)
     {
         oReturnCheck = Fapi_issueProgrammingCommand((uint32_t *)(address+i),(uint16_t *)(data+i),
                                                     8,0,0,
                                                     Fapi_AutoEccGeneration);
         while(Fapi_checkFsmForReady() == Fapi_Status_FsmBusy);
         SysCtl_delay (10);
         if(oReturnCheck != Fapi_Status_Success) return oReturnCheck;

     }
    Flash_DoneBank1 ();

I the result is always Fapi_Status_Success

This is the output in flash:

The next section starts at 0xC2400. That shows also on the picture. That is even shorter. 

 Any suggestion?

Thanks!

Hi,

Here are some tips for the debug:

1) Can you confirm the wait-state configuration that you did for Bank1 FMC? And what is the operating frequency?

2) I understand you mentioned that the sector is erased, but could you issue an erase command before the program loop? Just to make sure ECC space is also erased.

3) Regarding the success status return: Please search for "If the Fapi_issueProgrammingCommand() function does not wait for the program operation completion, how do we know whether the program operation succeeded or not?" in the Flash API wiki.  

Please include FMSTAT check to catch any program failure. 

4) Can you confirm that below functions are called with highlighted parameters before Bank1 Flash operations?

oReturnCheck = Fapi_initializeAPI(F021_CPU0_W1_BASE_ADDRESS, xxx);

if(oReturnCheck != Fapi_Status_Success)

{

Example_Error(oReturnCheck);

}

oReturnCheck = Fapi_setActiveFlashBank(Fapi_FlashBank1);

if(oReturnCheck != Fapi_Status_Success)

{

Example_Error(oReturnCheck);

}

5) I am sure you would have given pump access to Bank1 FMC.

Thanks and regards,

Hi Vamsi,

Thanks for the reply.
1) set the flash wait state to 0xF. and operating freq is 200Mhz. See code in 4).
2) The Jtag erase all the memory before the program start.
But I also before I start programming I erase all FLASH0 till FLASHAB.
This is the code I use for erasing:
Flash_CfgBank1 is call before the call.

Fapi_StatusType Flash_Erasebank (uint32_t address)
{
Fapi_StatusType oReturnCheck;
EALLOW;
DISABLE_INTERRUPTS;
oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,(uint32_t *) address);
while (Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}
ENABLE_INTERRUPTS;
return oReturnCheck;
}

3) I think I do that with this line:
while (Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}
4) Before I do a write /erase action I call this functiom:

Fapi_StatusType Flash_CfgBank1 (void)
{
volatile Fapi_StatusType oReturnCheck;
EALLOW;
Flash_setWaitstates (FLASH1CTRL_BASE,0x0F);
Flash_disableCache (FLASH1CTRL_BASE);
Flash_disableECC (FLASH1ECC_BASE);
Flash_claimPumpSemaphore (FLASHPUMPSEMAPHORE_BASE,FLASH_BANK1_WRAPPER);
oReturnCheck = Fapi_initializeAPI(((Fapi_FmcRegistersType *)F021_CPU0_W1_REGISTER_ADDRESS),200);
if (oReturnCheck != Fapi_Status_Success ) return oReturnCheck
oReturnCheck = Fapi_setActiveFlashBank(Fapi_FlashBank1);
if (oReturnCheck != Fapi_Status_Success ) return oReturnCheck
}

5) See the code in 4).

So I'm under the impression I did all the things you suggested.

Regards,



Note: This is the code I use for flash programming:

for(i=0;i<size;i+=8) // size is 1024
{
DISABLE_INTERRUPTS;
Flash_CfgBank1 (); // init the flash programming process
oReturnCheck = Fapi_issueProgrammingCommand((uint32_t *)(address+i),(data+i),
8,0,0,
Fapi_AutoEccGeneration);
while(Fapi_checkFsmForReady() == Fapi_Status_FsmBusy); // Waiting for FSM flag
if(oReturnCheck != Fapi_Status_Success) return oReturnCheck;
Flash_DoneBank1 ();
ENABLE_INTERRUPTS;
}

Hi,

This was part was missing in my cmd file.
GROUP
{
ramfuncs
.TI.ramfunc
{ -l C:\ti\C2000Ware_1_00_06_00_Software\libraries\flash_api\f2837xs\lib\F021_API_F2837xS_FPU32.lib }
// { -l ${COM_TI_C2000WARE_SOFTWARE_PACKAGE_INSTALL_DIR}\libraries\flash_api\f2837xs\lib\F021_API_F2837xS_FPU32.lib }
}LOAD = FLASHD,
RUN = RAMLS0,
LOAD_START(_RamfuncsLoadStart),
LOAD_SIZE(_RamfuncsLoadSize),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
RUN_SIZE(_RamfuncsRunSize),
RUN_END(_RamfuncsRunEnd),
PAGE = 0, ALIGN(4)

Can you please tell me how to use relative pads?

I successful tested flash programming. I still have some issues but I don't think there are related to flash programming.

Thanks!

Hi,

Glad the example helped.

I did not understand your question. What do you mean by relative pads?

Thanks and regards,
Vamsi

-l C:\ti\C2000Ware_1_00_06_00_Software\libraries\flash_api\f2837xs\lib\F021_API_F2837xS_FPU32.lib }

I only get this to work.

  { -l ${COM_TI_C2000WARE_SOFTWARE_PACKAGE_INSTALL_DIR}\libraries\flash_api\f2837xs\lib\F021_API_F2837xS_FPU32.lib }

And I needs something like? So how do I implement relative paths in the cmd file.
