Enc28j60 初始化成功但是ping不通复用spi1 定时器用TIM1

我用原子的开发板跑原子的例程没有问题虽然有时候会连接不上但是我实际现在用的stm32f103r8b 这款原理图连接到了复用的spi1 定时器资源早就用完了只能用定时器1 我用的板子做一个服务器，电脑那个用网络调试助手做一个客户端。
现在的问题是初始化能够成功但是ping 不通总是超时但是奇怪的是能在程序注释的arp那里停留我点连接很久之后能在注释有tcp/ip 那里停留但是返回的包长度为0，我想这应该是不用回发数据把。总的来说问题就是初始化能成功但是ping不通。

重要的不通的代码不通就是这几部分了我现在写一个只有这个网口的希望大神出来解救我！！
