任务五实现步骤：
1、准备环境：
Qemu+winimage
2、程序流程：
创建写日志接口
第一次日志是存储打印信息，所以在ksevice.c中的rt_kprintf里添加写入日志
3、效果
4、C源码
#include <rtthread.h>
#include <time.h>
#include <dfs_posix.h>

rt_kprintf("open file for append write failed\n");
return;
}
size = write(fd, buffer, sizeof(buffer));
if (size != sizeof(buffer))
{
rt_kprintf("append write data failed\n");
//加入LOG时间
//tmpStrLen = MyCAST_GetCurTime(tmpStr);
//tmpStrLen = sprintf(str, "[%s] ", tmpStr);
//strLen = tmpStrLen;
//加入LOG信息
tmpStrLen = sprintf(str,"%s",fmt);
