SDK版本：esp8266_nonos_sdk_v1.5.4
1、system_uart_swap()函数要放到什么地方才能屏蔽上电打印呢？
2、使用UART1打印日志，将官网的程序复制过来，总是出现错误。
官网程序：
void ICACHE_FLASH_ATTR uart_init_new(void)
{
// Wait for FIFOs to be emptied
UART_WaitTxFifoEmpty(UART0);
UART_WaitTxFifoEmpty(UART1);
// Configure UART settings
UART_ConfigTypeDef uart_config;
uart_config.baud_rate = BIT_RATE_74880;
uart_config.data_bits = UART_WordLength_8b;
uart_config.parity = USART_Parity_None;
uart_config.stop_bits = USART_StopBits_1
uart_config.flow_ctrl = USART_HardwareFlowControl_None;
uart_config.UART_RxFlowThresh = 120;
uart_config.UART_InverseMask = UART_None_Inverse;
UART_ParamConfig(UART0, &uart_config);
UART_IntrConfTypeDef uart_intr;
uart_intr.UART_IntrEnMask = UART_RXFIFO_TOUT_INT_ENA | UART_FRM_ERR_INT_ENA | UART_RXFIFO_FULL_INT_ENA;
uart_intr.UART_RX_FifoFullIntrThresh = 100;
uart_intr.UART_RX_TimeOutIntrThresh = 2;
uart_intr.UART_TX_FifoEmptyIntrThresh = 20;
UART_IntrConfig(UART0, &uart_intr);
// Set UART1 for printing
UART_SetPrintPort(UART1);
// Register interrupt handler
UART_intr_handler_register(uart0_rx_intr_handler);
ETS_UART_INTR_ENABLE();
｝
