rv1126-rv1109-RkLunch.sh

RkLunch.sh是个脚本,来自哪里

书接上回:rv1126-rv1109-瑞芯微的 IPC 程序_旋风旋风的博客-CSDN博客

修改之后

屏蔽了两行之后,就没有开机自启rklunch了:

#        [ -f /oem/RkLunch.sh ] && source /oem/RkLunch.sh

就是运行source /oem/RkLunch.sh

这里就跑了RkLunch.sh脚本

很简单的一个脚本,于是我剖析一下脚本,究竟是做了啥

这里是关键!                rkipc &

 ./oem/usr/bin/rkipc

运行了这个可执行文件进入摄像头预览demo:rkipc

编译相关的东西

主要代码在./app/rkipc

 

 这里就一个app了,后续大家有兴趣自己跟了,我到此为止了.我只是剖析一下开机自启的流程和原理,app代码部分就分析了
