10 程序改成带boot的app程序,串口中断接收变的不好使了

用RT-THREAD STUDIO 写的STM32F103VC程序,正常测试没有问题,改成带boot的app程序,串口接收就不好使了,只要一接收数据就卡死,然后看门狗超时重启,5个串口中断接收都有问题,1-4串口改成DMA+超时中断方式后通讯没有问题,可是UART5没有DMA,只能用中断串口接收方式,发送数据是没有问题的

void jump_app(void)
{
    if(checkApp())
    {
        update_data.UARTx = 1;
        update_SendStatusData("jump_app_OK", sizeof("jump_app_OK"));
        update_data.UARTx = 3;

        update_SendStatusData("jump_app_OK", sizeof("jump_app_OK"));
        update_data.UARTx = 5;
        update_SendStatusData("jump_app_OK", sizeof("jump_app_OK"));

        __HAL_UART_DISABLE_IT(&huart4, UART_IT_RXNE);
        __HAL_UART_DISABLE_IT(&huart5, UART_IT_RXNE);
        HAL_DeInit();
        iap_load_app(FLASH_APP_BAK);
    }
    else
    {
        update_data.UARTx = 1;
        update_SendStatusData("jump_app_NG", sizeof("jump_app_NG"));
        update_data.UARTx = 3;
        update_SendStatusData("jump_app_NG", sizeof("jump_app_NG"));
        update_data.UARTx = 4;
        update_SendStatusData("jump_app_NG", sizeof("jump_app_NG"));
        update_data.UARTx = 5;
        update_SendStatusData("jump_app_NG", sizeof("jump_app_NG"));
        iap_load_app(FLASH_BOOT_ADDR);
    }
}

跳转APP程序增加了恢复UART设置语句,还是不行
