stm32f407的drv_usart.c文件编译错误怎么解决？

STM32f407的drv_usart.c文件编译错误

    }

}
中的有一段关于流控的存在问题，会造成编译不通过,struct serial_configure结构体中不存在成员变量flowcontrol，代码如下：


switch (cfg->flowcontrol)
    {
    case RT_SERIAL_FLOWCONTROL_NONE:
        uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE;
        break;
    case RT_SERIAL_FLOWCONTROL_CTSRTS:
        uart->handle.Init.HwFlowCtl = UART_HWCONTROL_RTS_CTS;
        break;
    default:
        uart->handle.Init.HwFlowCtl = UART_HWCONTROL_NONE;
        break;
    }
初步推测是配置工具的问题，但是在stm32h753却没有出现这种问题，。
