本文介绍了一个C程序，用于测试NAND Flash的稳定性。程序通过读写文件并比较一致性来评估，使用`cp`, `md5sum`和`rm`命令，并在循环中运行，最后统计结果。" 104727120,9351948,Linux用户与用户组及磁盘管理指南,"['Linux系统', '用户与用户组', '磁盘管理']

下面的程序可以用来测试NAND Flash 稳定性，主要思想是反复读写NAND Flash上的文件及对比读写是否一致，最后统计结果。

test.c

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <sys/wait.h>
#include <sys/types.h>
#include <memory.h>

int main(int argc, char **argv)
{
if(argc < 4)
{
printf("argc is not enough, exit ! \n");
printf("Run as: ./test srcFile destFile loop \n");
exit(1);
}
