//ARM mini2440 資料光盤 /linux 目錄下找到，解壓到\tmp，然後sudo mv ,到\usr目錄下
網上資料·首先你得懂得，arm-linux-gcc4.4.3.tar.gz是一個交叉編譯器。
第一步：在文件系統目錄下解壓: tar zxvf arm-linux-gcc-4.4.3.tar.gz -c第二步：配置環境變量：在/etc/profile文件最末尾添加一行:
export set PATH=/opt/FriendlyARM/toolschain/4.4.3/bin:$PATH
第三步：ctrl+alt+backspace 註銷後重新登錄
測試：
第一步：檢查命令：which arm-linux-gcc
第二步：arm-linux-gcc hello.c -o hello
file hello (hello要自己編寫哦)
親自嘗試：
用網線連路由，DHCP默認，自動分配IP【不用改就行了】
【如果改了可能遇到的問題】【mini2440】LAN2:the file /etc/pcmcia/network.opts does not exist.please restore this file
忽略，進網絡設置-ok-succes
[ubuntu 12.04]

-----然後，mini2440->/home/plg/剛剛傳送的文件
terminal># ls
#cd /home/plg

然後 chmod u+x hello # ./hello 完美解決
更新源：摘
1、首先備份Ubuntu12.04源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （備份下當前的源列表）
2、修改更新源
sudo gedit /etc/apt/sources.list （打開Ubuntu 12.04源列表文件）
3、把裏面的列表替換成下面的列表
