采用一个低优先级任务去初始化，让任务去等待网络连接，这样等网络连接后，可以初始化成功，而且网线插拔都可以正常使用。

你好。我现在也在调试这个，你解决了吗，可以发个代码学习学习吗。QQ 2902926270

我的f4板子拔出网线，EXTI15_10_IRQHandler没有调用，不知道为什么
|
|
|
|
|
|
我也在调试。可以用了，但是网线插入之后，中断不一定能上来。
不知道原因？谁能解答一下。 我用万用表测试7脚的输出电压，发现只能变化一次，后来再无变化。（这个还是取决于代码Eth_Link_PHYITConfig(DP83848_PHY_ADDRESS);的定义，否则，一点都不变化） 是否我的思路有问题？谢谢。 |

不插网线不可能初始化。这就是这样的，不插网线上电干什么

终于搞定啦。。。。。。。。。。。

我在 STM32F107 上已经实现了，和你的问题描述有点不一样：不插网线初始化LWIP，臣妾做不到... 插入网线正常通信，臣妾做到了这个是：不插网线开机，定时5s不断初始化网口，一旦插上网线并且网口初始化成功后再初始化LWIP。之后就可以正常运行，热插拔也没问题。
项目上正在使用，目前没什么问题。 用了ucosii 的官方例程或者大神们移植的程序 首先在BSP_Init() 中找到 ETH_BSP_Config();再找到 Ethernet_Configuration();（程序中我注释了，原因是把这个函数放到任务中定时调用） void ETH_BSP_Config (void) { /* Configure the GPIO ports for ethernet pins */ ETH_GPIO_Config(); /* Config NVIC for Ethernet */ ETH_NVIC_Config(); /* Configure the Ethernet peripheral */ // Ethernet_Configuration(); ｝ 打开 Ethernet_Configuration();找到 ETH_Init(Ð_InitStructure, PHY_ADDRESS);这个函数是初始化网口的，是否连接上网口这个函数返回值不同 用 ETH_Link_Flage 在任务中判断网口是否初始化成功（是否插上网线），连上了就删除初始化网口的任务。以后不管插拔网线都可以连上 建议去仔细看看 uint32_t ETH_Init(ETH_InitTypeDef* ETH_InitStruct, uint16_t PHYAddress) 中干了什么！！！ void Ethernet_Configuration (void) { . . . . /* Configure Ethernet */ ETH_Link_Flage = ETH_Init(Ð_InitStructure, PHY_ADDRESS); /* Enable the Ethernet Rx Interrupt */ ETH_DMAITConfig(ETH_DMA_IT_NIS | ETH_DMA_IT_R, ENABLE); } 下面是初始话网口的任务 void Net_Init (void *pdata) { extern u8 ETH_Link_Flage while(1) { if(ETH_Link_Flage == 1) { LwIP_Init(); LwIP_Pkt_Sem = OSSemCreate(0); OSTaskCreate(LwIP_Pkt_task, (void *)NULL, (OS_STK *)&LwIP_Pkt_Task_STK[LwIP_Pkt_STK_Size-1], LwIP_Task_PRIO); OSTaskDel(NetInit_TASK_PRIO); } else { Ethernet_Configuration(); } OSTimeDlyHMSM(0,0,5,0); } } |
