其次，在linux端敲入如下命令：
 
mount   -t   smbfs   -o   username=Administrator,password=****   //IP/share   /mnt/share/
 
注意：
username 是指windows登陆的用户名
password 是指windows登陆的密码]]>https://blog.youkuaiyun.com/hemmanhui/article/details/5824134https://blog.youkuaiyun.com/hemmanhui/article/details/5824134hemmanhuiThu, 19 Aug 2010 15:37:00 +0800在调试板子的时候，发现在PATH对应的路径中没有alias这个命令，但是居然可以用，
 
查阅资料后，终于明白shell是如何执行命令解释了。
 
首先shell判断用户输入的命令是否是内部命令
 
*是内部命令，直接执行
*不是内部命令，在PATH对应的目录中搜索对应的单独的程序，存在执行，不存在报错
 
linux的命令可以分为内部命令和外部命令。
内部命令在系统启动时就调入内存，是常驻内存的]]>https://blog.youkuaiyun.com/hemmanhui/article/details/5731729https://blog.youkuaiyun.com/hemmanhui/article/details/5731729hemmanhuiTue, 13 Jul 2010 14:28:00 +0800在实际嵌入式开发过程中，可能需要新增一些自定义的控制宏，microwindows中加入控制宏的步骤如下：
 
1. src目录下config
ST_AUTO_FACTORY_SUPPORT = N
或
ST_AUTO_FACTORY_SUPPORT = Y
 
2.   src目录下Makefile.rules
ifeq ($(ST_AUTO_FACTORY_SUPPORT),Y)

unaligned userspace access 错误
 
结果修改一下makefile中的编译选项，加入：
-g -O2 -Wno-deprecated
 
再次运行就正常了，估计这种错误与编译优化有关系
