我用F021里面的写函数写内部flash，可以写，写EEPROM有时候能写，有时候写不进去

uint32_t Fapi_BlockProgram( uint32_t Bank, uint32_t Flash_Address, uint32_t Data_Address, uint32_t SizeInBytes)
{
   register uint32_t src = Data_Address;
   register uint32_t dst = Flash_Address;
   uint32_t bytes;

   if (SizeInBytes < 16)
       bytes = SizeInBytes;
   else
       bytes = 16;

   if ((Fapi_initializeFlashBanks((uint32_t)SYS_CLK_FREQ)) == Fapi_Status_Success)
   {
       (void)Fapi_setActiveFlashBank((Fapi_FlashBankType)Bank);
       // if(Bank >= 7)
             Fapi_enableEepromBankSectors(0xf, 0);
       //else
             //(void)Fapi_enableMainBankSectors(0xFFFF);                    /* used for API 2.01*/
   }else
   {
         return (1);
   }

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

    while( SizeInBytes > 0)
   {
       Fapi_issueProgrammingCommand((uint32_t *)dst,
                                   (uint8_t *)src,
                                   (uint32_t) bytes,
                                   0,
                                   0,
                                   Fapi_AutoEccGeneration);

        while( FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmBusy );
        while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);

       src += bytes;
       dst += bytes;
       SizeInBytes -= bytes;
        if ( SizeInBytes < 16){
           bytes = SizeInBytes;
        }
    }
   return (0);
}

写不进去的时候会卡在第二个while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);这里

请问您现在使用的是哪款芯片？能否请您详细说明下问题，谢谢

startup.c文件中的
/* initialize the C global variables */
if (&__TI_Handler_Table_Base < &__TI_Handler_Table_Limit)
{
uint8_t **tablePtr = (uint8_t **)&__TI_CINIT_Base;
uint8_t **tableLimit = (uint8_t **)&__TI_CINIT_Limit;

while (tablePtr < tableLimit)
{
uint8_t *loadAdr = *tablePtr++;
uint8_t *runAdr = *tablePtr++;
uint8_t idx = *loadAdr++;
handler_fptr handler = (handler_fptr)(&__TI_Handler_Table_Base)[idx];

(*handler)((const uint8_t *)loadAdr, runAdr);
}
}
这段是什么意思？我之前把这段屏蔽了，就不能写成功，加上这段就可以写EE和flash

我现在需要把这个startup.c中的程序放到sram中运行，怎么设置link.cmd文件，我尝试了几次都不可以
