本章主要介绍 飞凌OKA40i-C / OKT3-C 开发板 (https://www.forlinx.com/product/a40i-58.html)开机自启动应用与LCD屏幕配置的方法,其它平台请参考使用。
两款板卡均采用国产芯片设计研发,OKT3-C开发板基于全志四核车载导航处理器设计开发,OKA40i-C开发板基于全志 四核工业级处理器设计开发。
一、开机自启动方法
开机自启动脚本为/autorun.sh,可以将开机需要进行设置的命令可以在此脚本中加入。假设开机时自动执行/root/loop.sh,在/autorun.sh中加入:
source /root/loop.sh &
关闭开机启动qt程序。
修改/etc/init.d/rcS 注释掉runqt。
