经过半个月的时间，终于把LwIP程序包成功移植到我的系统中了，并能正常运行。TCP UDP ICMP各个协议也能正常运行。。。都乖乖的在ARM中跑着，呵呵……看着屏幕的调试信息。看着服务端接收到我发的数据[TCP协议和UDP协议都能接收到]，心里有点高兴，但是还是有点忧郁，这么长时间以来，我被这个东西时刻的困饶着我，就连做梦都好几次是在是修改程序。写发送信号量程序，一步一步的跟踪，什么时候该发送邮箱，什么时候该接收邮箱，每个结构体都是做什么用的，把我搞的睡觉也不塌实。。。。好几次的睡觉都是写了一夜的程序，好累好累，早上起来脑袋还处在昏沉沉的状态。。。。。。
下面就是在屏幕上打出来的调试信息。
