使用FTP可直接登录 linux虚拟机上，进行远程操作
要是使用的是一期的****和老版本的UBUNTU进入需要使用
sudo chown book:book /work -R
//对work工作目录的使用权限进行更改
没有更改前只对root用户的开放
//更改之后会对 book用户开放使用
tar xjf u-boot-1.1.6.tar.bz2 //解压uboot文件使用

//注 因为老版本的 makefile与新版本的make 有部分不兼容会出现如下的错误
Makefile:416:*** mixed implicit and normal rules: deprecated syntax
Makefile:1449:*** mixed implicit and normal rules: deprecated syntax这是因为使用 make 比 文件中的make 较新导致的，因此需要进行如下更改即可
对416行进行修改
将
config %config: scripts_basic outputmakefile FORCE更改为
%config: scripts_basic outputmakefile FORCE将1449行
/ %/: prepare scripts FORCE更改为
%/: prepare scripts FORCE若是在进行 make uImage指令之后出现
"mkimage" command not found - U-Boot images will not be built需要进行手动的 uboot工具安装，安装的命令如下：；
sudo apt-get install u-boot-tools然后在进行
make uImage
