关于TMS570LS3137片上flash读写问题

我的目的是要将数组大小为64的0-63的数，写入到bank1中，但是我通过写操作后，读出来只写进入0-15,后面16-63都没有写入，因为我用读的api和直接访问物理地址的数是一样的都只有0-15，下面是我的代码：

oReturnCheck = Fapi_BlockProgram( ucBank, g_test_Address, (uint32_t)&data_test_buf[0], g_test_Size);
	if(oReturnCheck)
	{
		// Indicate that the flash programming failed.
		printf("\r Program Flash failed:  \r\n");
		return;
	}
	oReturnCheck = Fapi_UpdateStatusProgram( ucBank, g_test_Address, (uint32_t)&data_test_buf[0], g_test_Size);
	if(oReturnCheck)
	{
		// Indicate that the flash programming failed.
		printf("\r check Program Flash failed:  \r\n");
		return;
	}
	printf("\r check Program Flash success:  \r\n");

	printf("data_test_buf:");
	for(i = 0;i<BUFFER_SIZE;i++)
	{
		printf("%d,",data_test_buf[i]);
	}
	printf("\r\n");
	printf("Program Flash success\r\n");


	oReturnCheck = Fapi_BlockRead(ucBank, g_test_Address, (uint32_t)data_read_buf, g_test_Size);
	if(oReturnCheck)
	{
		printf("read is error\r\n");
	}
	else
	{
		printf("data_read_buf:");
		for(i = 0;i<BUFFER_SIZE;i++)
		{
			printf("%d,",data_read_buf[i]);
		}
		printf("\r\n");
		cur_buf = (uint32_t*)g_test_Address;
		printf("cur_buf:");
		for(i = 0;i<BUFFER_SIZE;i++)
		{
			printf("%d,",cur_buf[i]);
		}
		printf("\r\n");
	}

从结果看应该是写入的时候发生的错误，但是不知道是哪里错了。写函数如下所示：

//Bank here is not used. We calculate the bank in the function based on the Flash-Start-addr
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);
	     (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);
}

这个函数是bootloader中的我是直接移过来使用。

大神帮忙看看这个问题。
