1. 交叉編譯環境搭建:

(1)[email protected]:/home/caihuanming#          #不是root使用者

tar xvf arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 -C ./      #注意是xvf不是xvzf

(2)[email protected]:/home/caihuanming#

export PATH=$PATH:/home/caihuanming/gcc-3.4.5-glibc-2.3.6/bin

(3)[email protected]:/home/caihuanming#echo $PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/caihuanming/gcc-3.4.5-glibc-2.3.6/bin

(4)sudo vim /etc/environment

source /etc/environment

(5)PATH=”/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/caihuanming/gcc-3.4.5-glibc-2.3.6/bin”

2.交叉工具鏈

(1)編譯 產生led.o

arm-linux-gcc –g –c led.S

(2)連結 產生led.elf   運用led.lds連結器指令碼

arm-linux-ld –Tled.lds –o led.elf

(3)讀led.elf資訊 大下端 執行平臺 類似

arm-linux-readelf –a led.elf

(4)反彙編hello輸出到dump資料夾

arm-linux-objdump –D –S hello >dump

(5)格式轉換 產生led.bin

arm-linux-objcopy –O binary led.elf led.bin
