2.sudo apt-get update

3.安装nfs服务
  sudo apt-get install nfs-kernel-server(install nfs server)
  sudo gedit /etc/exports add "/home/lzd/nfs *(rw,sync,no_root_squash)"
  sudo exportfs -r (restart the nfs server)
  sudo /etc/init.d/nfs-kernel-server restart
  sudo mount -t nfs 10.107.4.145:/home/lzd/nfs /mnt (test if ok)
4.安装编译内核需要的工具
  sudo apt-get install build-essential libncurses5-dev
5.安装串口通讯工具，支持zmodem协议。
  sudo apt-get install minicom lrzsz
  minicom -s (config it as ttyS0)
6.安装kscope

好了，我的就是这样了。
