TMS570LS1224: Reflashing at a location issue

vidya m k

Part Number: TMS570LS1224

Tool/software:

Hi,

I'm using FAPI commands to erase and write in flash memory. Since the memory must be erased before rewriting, I first issue an erase command and then use Fapi_issueProgrammingCommand to write. The erase and write process executes successfully the first time. However, on the second attempt, the process gets stuck during the erase step when executed in a single run. Interestingly, when executing the process step by step, the reflashing occurs correctly. Could you please help with this issue?

Thankyou.

Hi Vidya,

You are writing on which bank?

We have two banks in LS1224, Bank-0 and bank7, so on which bank you are writing using FAPI?

Is it possible to share your code for quick understanding the exact process you are doing?

Thanks & regards,

I'm writing in Bank 0.

this is the code used to Erase.

uint8_t ErasenVerify(uint32_t MemAddr)
{
Fapi_StatusType oReturnCheck = Fapi_Status_Success;

flashWREG->FRDCNTL = 0x0110U; /*RWAIT = 1, for 80MHz system clock*/

FAPI_WRITE_EWAIT(5U); /*EWAIT = 3*/

Fapi_issueAsyncCommand(Fapi_ClearStatus);

oReturnCheck = Fapi_initializeFlashBanks(SYS_CLK_FREQ);
if(oReturnCheck == Fapi_Status_Success);
{
oReturnCheck = Fapi_setActiveFlashBank(Fapi_FlashBank0);
if( oReturnCheck == Fapi_Status_Success)
{
oReturnCheck = Fapi_enableMainBankSectors(0xFFFF);
if( oReturnCheck == Fapi_Status_Success)
{

while( FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady );

if(FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmReady)
{
oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, MemAddr);

while( FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady );
if( FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmReady )
{
if(FAPI_GET_FSM_STATUS == 0 )
return 1;
else
return 0;
}
//verify the erased state
//Fapi_doBlankCheck(0x00024000,0x0011BFFF,poFlashStatusWord);
}
}
}
}

}
