Android 开机大致流程

从打印的开机Log 信息可以总结出Android 开机的大致流程如下：

Android 开机大致流程

3. 开机震动添加方法（MTK 、展讯平台）一、MTK 平台lk 层添加开机震动的方法文件修改大致路径以MT6739 平台为例，大致路径如下vendormediatekproprietaryootableootloaderlkplatformmt6739a. 修改platform.c文件

在platform.c文件中的mboot_common_load_logo 方法显示开机Logo之前添加震动

platform.c

// add for lk viber vibr_Enable_HW();//开启震动 mdelay(80); //震动80ms vibr_Disable_HW();//关闭震动 // add for lk viber mboot_common_load_logo((unsigned long)mt_get_logo_db_addr_pa(), "logo"); // add for lk viber vibr_Enable_HW();//开启震动 mdelay(80); //震动80ms vibr_Disable_HW();//关闭震动 // add for lk viber mboot_common_load_logo((unsigned long)mt_get_logo_db_addr_pa(), "logo");b. 查看mt_pmic.h头文件
