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：
struct platform_device device_adc = {
.name = "rk30-adc",
.id = -1,
.num_resources = ARRAY_SIZE(rk30_adc_resource),
.resource = rk30_adc_resource,
.dev = {
.platform_data = &rk30_adc_pdata,
},
};platform_driver代码在drivers/adc/plat/rk30_adc.c 中，实现了start, stop, read函数；
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
- dev->class = power_supply_class;
- dev->type = &power_supply_dev_type;
- dev->parent = parent;
- dev->release = power_supply_dev_release;
- dev_set_drvdata(dev, psy);
- psy->dev = dev;
主要是为 dev->type和psy->dev赋值，并且power_supply_class_init函数中：
- power_supply_class->dev_uevent = power_supply_uevent;
使得后续kobject_uevent上报的是power_supply_uevent的内容，位于 drivers/power/power_supply_sysfs.c中；
在上层cat时候显示的则为power_supply_sysfs.c中
- #define POWER_SUPPLY_ATTR(_name) \
- { \
- .attr = { .name = #_name }, \
- .show = power_supply_show_property, \
- .store = power_supply_store_property, \
- }

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：
static int mu509_io_deinit(void)
{
return 0;
}
struct rk29_mu509_data rk29_mu509_info = {
.io_init = mu509_io_init,
.io_deinit = mu509_io_deinit,
.modem_power_en = RK30_PIN0_PC6,
.bp_power = RK30_PIN2_PD5,
.bp_reset = RK30_PIN0_PB4,
.ap_wakeup_bp = RK30_PIN0_PC4,
.bp_wakeup_ap = RK30_PIN0_PC5,
};
struct platform_device rk29_device_mu509 = {
.name = "mu509",
.id = -1,
.dev = {
.platform_data = &rk29_mu509_info,
}
};
GPIO逻辑控制代码在kernel/drivers/misc/bp/chips中
3.
编译步骤
kernel:
cd kernel;
make ARCH=arm rk3188_ABC_3gonlydata_defconfig menuconfig
make ARCH=arm rk3188_ABC_3gonlydata_defconfig
make kernel.img
android:
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

wifi-bt模块AP6210
看/sys/class/rkwifi节点有没有出来，接着cat /sys/class/rkwifi/chip看芯片型号对不对，这部分的实现代码在kernel/drivers/net/wireless/wifi_sys/rkwifi_sys_iface.c中。
照着RK的文档配置好了WIFI，log提示没有问题，点击后界面一直提示正在搜索网络，但是一直没有结果出来。原来是由于kernel中WIFI模块晶振配置不正确，应该为26M，却是配置成了24M。修改完成重烧kernel后启动，马上搜索到网络了
bt打开马上关闭，提示如下log:

原因，kernel/net/rfkill/rfkill-rk.c 中是控制BT GPIO的驱动，由于二合一模块共用一个电源，WIFI已经打开了模块电源，BT时候又申请该GPIO去控制电源，导致直接返回，没有往下执行其他动作，把BT的电源控制GPIO去掉即可，成功的LOG如下：

5. 开机静态LOGO的制作
取一张和屏幕分辨率一样的bmp或者png格式图片(其他格式应该也可以)，用GIMP图片编辑器打开，在图像->模式->索引中，将最大颜色数量由256改成224，然后点击“转换”进行转换，接着 文件->导出，选择文件类型为ppm格式，然后导出，接着弹出的对话框选择ASCII码保存，即可生成ppm格式图片；
进入kernel/driver/video/logo中，找到logo_linux_clut224.ppm和logo_linux_clut224.c文件删除，刚才制作的图片重命名为logo_linux_clut224.ppm，然后编译kernel即可
注意生成的ppm图片比较大，但是编译出来的kernel是很小的。
全志平台第一张开机logo制作又不一样：
首先用ps打开bmp logo,在右边点击“通道”，如果显示的不是RGB，而是索引；那么在菜单 图像->模式中选择RGB颜色。这时候再看“通道”就可以显示RGB 红绿蓝图层了，但是还不行，点击”通道“旁边的按钮选择”新建通道“ ,默认名字alpha 1通道即可，这样红绿蓝图层后就多了一个alpha 1图层，将图片另存为bmp格式即可
编译RK4.2.2错误解决方法：
Copying: out/target/common/obj/APPS/ContactsProvider_intermediates/emma_out/lib/classes-jarjar.jar
错误：读取 out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/javalib.jar 时出错；invalid header field
1 错误

make: *** [out/target/common/obj/APPS/KeyChainTests_intermediates/classes-full-debug.jar] 错误 41
make: *** 正在等待未完成的任务....
解决：
$ cd out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/
$ rm javalib.jar classes-full-debug.jar
$ sudo update-alternatives --config jar
有 2 个候选项可用于替换 jar (提供 /usr/bin/jar)。
选择 路径 优先级 状态
------------------------------------------------------------
* 0 /usr/bin/fastjar 100 自动模式
1 /usr/bin/fastjar 100 手动模式
2 /usr/lib/jvm/java-6-sun/bin/jar 63 手动模式
要维持当前值[*]请按回车键，或者键入选择的编号：2
update-alternatives: using /usr/lib/jvm/java-6-sun/bin/jar to provide /usr/bin/jar (jar) in 手动模式
$ croot
$ make -j4
完毕！
RK system.img 的打包方法：

RK lcd参数配置：
新曾一个LCD，在kernel/drivers/video/rockchip/screen中增加一个文件如lcd_ZS070IH5030B3H7.c，lcd.h是自动生成的，具体看Makefile文件
其中一些参数的意义：
RK3026 android4.2修改kernel logo:
#pngtopnm logo_linux_clut224.png>logo_linux.pnm
#pnmquant 224 logo_linux.pnm > logo_linux_224.pnm
#pnmtoplainpnm logo_linux_224.pnm>logo_linux_clut224.ppm
RK3126 android4.4.4/RK3288 5.1的调试问题：
kernel启动logo的制作，用PS制作bmp图片时候要在菜单 图像->模式中选索引颜色，弹出的确定用默认值即可，保存时候选window和8位
否则制作出来的logo混乱；
recovery和充电logo转了180度，修改device中BOARD_HAS_FLIPPED_SCREEN即可，不过记得要进到bootable/recovery/minui中去mm -B;然后到bootable/recovery/中 mm -B,否则不生效啊
RK g-sensor方向调试：
最好的办法是在上报ABS_X,ABS_Y,ABS_Z中打印出上报的xyz三个值，把平板平放桌面上，xy值接近或等于0，z接近98000；
y轴竖起与桌面垂直，xz接近0，y接近98000；x轴竖起与桌面垂直，yz接近0，X接近98000；
一般要修改的地方：xyz为负数，上报时候加上-号即可；xy对调了，那么ABS_X上报y的值，ABS_Y上报x的值即可
