1）. 安装过程:

$ tar zxvf nuc980bsp.tar.gz
$ cd nuc980bsp
$ sudo ./install.sh
Now installing arm_linux_4.8 tool chain to /usr/local
Setting tool chain environment
Installing arm_linux_4.8 tool chain successfully
Install rootfs and pre-build image
Please enter absolute path for installing(eg:/home/<user name>) :
BSP will be installed in /<path you input>
/opt/nuc980bsp
Create /opt/nuc980bsp 
/opt/nuc980bsp/nuc980bsp
./install.sh: line 153: Check: command not found

2). 安装后查看资源:

$ ls /opt/nuc980bsp/nuc980bsp/
image/  rootfs/ 
$ ls /usr/local/arm_linux_4.8/   #脚本自动安装的交叉编译路径
arm-nuvoton-linux-uclibceabi  bin  i686-pc-linux-gnu  include  lib  libexec  sbin  share  usr

3). 安装补丁 和 注意事项:

1). 更过国内安装源的,请更换为ubuntu安装源(可网上自行搜索 ubuntu安装源 );
 	 常见错误是安装包无法安装,等类似错误。
2). 目前计算机一般都是64位机,安装ubuntu16 & 18 也是64位,交叉编译环境需要增加如下补丁.	
  	aptitude -y install libc6-dev-i386 
	aptitude -y install lib32z1 
	aptitude -y install lib32ncurses5  
	ubunt16
	aptitude -y install ia32_libs  		/** 注意此版本问题 */
	ubunt18
	sudo apt-get install lib32stdc++6

否则出现常见错误，类型:
arm-linux-gcc, No such file or directory 类似错误。
libstdc++.so.6: cannot open shared object file: No such file or directory：
原因在于，ubuntu 18.04 版本 ia32_libs 被废弃了导致没有32位的lib库。

4). 配置环境变量:

$ sudo gedit /etc/profile
在文件中增加入选内容:
#nuc980iot cross_compile
export ARCH=arm
export CROSS_COMPILE=/usr/local/arm_linux_4.8/bin/arm-nuvoton-linux-uclibceabi-         #缺省安装路径
export PATH=/usr/local/arm_linux_4.8/bin:$PATH											#注意注意注意>> :$PATH
