CCS/TMDXRM46HDK: [F021] Fapi_issueProgrammingCommand failed - PGV=1

Tool/software: Code Composer Studio

Hi,

 I'm trying to use F021 Flash API to erase the flash then load a new program.

1-) I copy some code on the RAM memory.

2-) I run this code to clear the flash.

void erase()
{
    uint32_t s = 0;
    Fapi_StatusType r = Fapi_initializeFlashBanks(128);

    ENABLE_CPU_PRIVILEGE_MODE;

    Fapi_FlashBankSectorsType type;
    r = Fapi_getBankSectors(Fapi_FlashBank0, &type);

    while (FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady);
    s = FAPI_GET_FSM_STATUS;

    r = Fapi_setActiveFlashBank(Fapi_FlashBank0);
    r = Fapi_enableMainBankSectors(32);

    while (FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady);

    uint32_t* flash = (uint32_t*)(0x00014000);

    r = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, flash);

    while( FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmBusy );
    do
    {
        s = FAPI_GET_FSM_STATUS;
    }while(s != Fapi_Status_Success);

    DISABLE_CPU_PRIVILEGE_MODE;
}

From the memory browser view, I can see that the memory for this banking sector is filled with 1.

3-) I try to write something in the flash

void program()
{
    uint32_t s = 0;
    Fapi_StatusType r = Fapi_initializeFlashBanks(128);

    ENABLE_CPU_PRIVILEGE_MODE;

    while (FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady);
    s = FAPI_GET_FSM_STATUS;

    r = Fapi_setActiveFlashBank(Fapi_FlashBank0);
    r = Fapi_enableMainBankSectors(32);

    while (FAPI_CHECK_FSM_READY_BUSY != Fapi_Status_FsmReady);

    uint8_t tmp[8]={0};


    r = Fapi_issueProgrammingCommand((uint32_t*)(0x00014000),
                                         tmp,
                                         8,
                                         0,
                                         0,
                                         Fapi_AutoEccGeneration);

    while( Fapi_checkFsmForReady() == Fapi_Status_FsmBusy );
    do
    {
        s = Fapi_getFsmStatus(); //0x00001010
    }while(s != Fapi_Status_Success);

    DISABLE_CPU_PRIVILEGE_MODE;
}

Fapi_issueProgrammingCommand failed to write in the flash memory.

In FMSTAT register, PGV is set to 1.

The documentation states :

Program verify When set, indicates that a word is not successfully programmed after the maximum allowed number of program pulses are given for program operation.

I don't understand why writing fails.

Thanks
