在FPGA上移植操作系统时用到的补丁，建立交叉编译环境NIOS2

　　 践踏堆栈 [C语言编程] n. 在许多C语言的实现中,有可能通过写入例程 中所声明的数组的结尾部分来破坏可执行的堆栈. 所谓 践踏堆栈 。使用的 代码可以造成例程的返回异常,从而跳到任意的地址.这导致了一些极为险恶的数据相关漏洞-trampling stack [C programming language] n. In many C language implementation, it may be passed into routines statement by the end of the array to undermine executable stack. The so-called abuses stack. The code can cause abnormal return to the routines, jumping arbitrary address. This has led to some extremely dangerous loopholes in the relevant data

linux 下的ping源码，用socket实现，刚学linuxs socket编程的可以下载阅读。当然，你可以把该程序移植到嵌入式系统中。-ping source code under linux, using socket implementation, just learning linuxs socket programming can be downloaded to read. Of course, you can put this program ported to an embedded system.
