本章主要介紹 飛凌OKA40i-C / OKT3-C 開發板 （https://www.forlinx.com/product/a40i-58.html）開機自啟動應用與LCD屏幕配置的方法，其它平臺請參考使用。
兩款板卡均采用國產芯片設計研發，OKT3-C開發板基于全志四核車載導航處理器設計開發，OKA40i-C開發板基于全志 四核工業級處理器設計開發。
一、開機自啟動方法
開機自啟動腳本為/autorun.sh，可以將開機需要進行設置的命令可以在此腳本中加入。假設開機時自動執行/root/loop.sh，在/autorun.sh中加入：
source /root/loop.sh &
關閉開機啟動qt程序。
修改/etc/init.d/rcS 注釋掉runqt。
