RK3188笔记

1.

电量检测用SARADC_ANI0通道，platform_device代码在arch/arm/machrk30/devices.c中：

[cpp]  

01. structplatform_devicedevice_adc={

02. .name="rk30‐adc",

03. .id=‐1,

04. .num_resources=ARRAY_SIZE(rk30_adc_resource),

接着电量检测上报代码在power/rk30_factory_adc_battery.c中，注册到drivers/adc/core.c中，通过回调start,read等进行电量的读取上报动作；

上层system/core/charger/charger.c中检测上报的事件，如果全部offline或者超时则会重启机子。

power上报机制：

drivers/power/power_supply_core.cpower_supply_register函数中

[cpp]

01. dev‐>class=power_supply_class;

02. dev‐

>type=&power_supply_dev_type;

03. dev‐>parent=parent;

在上层cat时候显示的则为power_supply_sysfs.c中

所定义的内容。

2.

3G

3G唤醒主机原理：

在3G中断到来时候调用wake_lock_timeout(&bp>bp_wakelock,10*HZ);上层会保持不休眠

平台的gpio定义在boardrk3188rk6163gonlydataABC.c中：

GPIO逻辑控制代码在kernel/drivers/misc/bp/chips中

3.

编译步骤

A.高清屏需要配置:vimdevice/rockchip/rk30sdk/BoardConfig.mk将下面两个宏改为

true

BOARD_USE_LCDC_COMPOSER:=true

BOARD_LCDC_COMPOSER_LANDSCAPE_ONLY:=true

B.执行make

C.执行./mkimage.sh

即可在rockdev/Image目录下生成以下4个img

system.imgboot.imgrecovery.imgmisc.img
