STM32F407VET6 + IP101GRI网络移植后ping不成功

发布于 2019-08-16 23:31:14 浏览：3869 订阅该版

硬件：
主控：SMT32F407VET6
PHY: IP101GRI

软件:
系统：已经参考教程移植系统成功
网络：已经根据教程修改了寄存器的地址，使用静态IP调试

目前的现象：

1.接上路由器后，路由器的RJ45灯亮，但闪烁较慢
2.使用wireshark抓不到任何终端发送出来的数据包
3.网络驱动的调试日志如下：会出现receive frame faild的错误

4.LWIP的调试日志如下：

5.使用list_thread查看，接收和发送线程有运行

6.使用ifconfig查看，因为使用静态IP所以可以显示预设的IP和网关及子掩码

7.Ping路由器的话会全部超时

自我分析：
1.网口灯会亮且能协商速率成功，PHY芯片应该配置成功了。
2.但无法发送和接收数据是否LWIP有问题？

问题需求：
1. 已经排查一天，因对RT-Thread不是很了解，暂时不知道从哪些方面去排查问题。
2. 麻烦大家给我指明可能存在的问题

调网络不抓包，调I2C等时序不上逻辑分析仪，就像电工不用万用表！多用整理的好的文字，比截图更省流量，还能在整理过程中思考。

这家伙很懒，什么也没写！

>日志只看到发包没看到收包，速度识别为10M，感觉硬件有问题，一般都是100M全双工的。 ...

我修改了drv_eth.c中的rt_stm32_eth_init(rt_device_t dev)函数的中的EthHandle.Init.AutoNegotiation = ETH_AUTONEGOTIATION_ENABLE;

现在ping能够ping通，但会丢包，调试日志发现很多接收失败的报文
