客户在全志R16平台的问题合集20171128

2017/10/19 16:41

版本：V1.0

W工，您好！

问题1：

我是XXXXXX科技有限公司的陈工，在调试贵公司的R16开发板（系统为安卓4.4）的LVDS屏的时，你们的屏幕是1280x800,18位的屏，我们的是（分辨率为）1024x600、18位的屏，我修改了下面的信息，但是开机后整体画面有偏移，画面偏左而且没有占满整个屏（附件图中红框部分属于屏幕正常显示区域），下方的几个虚拟按键也没有显示出来。我修改行后沿时间跟场后沿时间并没有效果，请问还需要做什么修改吗？

lcd_x = 1024

lcd_y = 600

lcd_hbp = 220

lcd_ht = 1400

lcd_hspw = 60

lcd_vbp = 7

lcd_vt = 800

lcd_vspw = 10

屏幕验证过，右边的黑边鼠标能拖过去，能显示在上面。

LVDS接口的LCD屏幕右边有黑条.jpg

lvds格式的lcd的屏幕参数配置.png

马上想起来很久很久碰到的一个问题，通过全志A31S平台的HDMI接口输出854x480分辨率（TI的DLP）的时候，看见右边有一个黑条，调了一个星期，做驱动的和做Android的在扯皮！后来做硬件的一句话：你们看看，那个黑条是不是Android的虚拟导航条？最后那个做Android的小子咬死不承认问题，在老大强烈要求之后，那个小子才将虚拟导航条的宽度缩减了一半，马上黑条变小了。最后他不得已修改为宽度为0，解决问题了。

解决方法：

修改了/android/frameworks/base/core/res/res/values/dimens.xml里的status_bar_height修改成0，然后把android/frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java里的addNavigationBar();方法屏蔽掉

Q:\r16v11\gc2035_parrotv1.1\android\frameworks\base\core\res\res\values\dimens.xml

mIconPolicy = new PhoneStatusBarPolicy(mContext);

mHeadsUpObserver.onChange(true); // set up

mContext.getContentResolver().registerContentObserver(

Settings.Global.getUriFor(SETTING_HEADS_UP), true,

}

问题2：

假如把开发板上的wifi模块改成AP6210应该怎么修改，我修改了/android/device/softwinner/astar-evb30目录下的astar_evb30.mk 文件和BoardConfig.mk 文件，但打开wifi时会报错（参附件6210.txt）

由于AP6210正基已经停产，退出了支持序列。不需要浪费时间了！

问题3：

电源管理芯片我想设置DLDO3,输出为2.8V，我给寄存器地址0x12写入0xff，把DLDO3开关控制寄存器打开，根据计算往寄存器地址0x17写入0x15，但是并没有输出电压，开机信息读寄存器的值，读出的值是我写进去的值（红色箭头处是我写进去的值）。

电源1 Catch(11-28-12-4(12-11-15-35-19).jpg

电源2 CatchBFDC(11-28-(12-11-15-35-19).jpg

（你们应该是要配置摄像头的电压^_。下次提问的时候可以说明一下你们的目的，这样我回答问题更有针对性！）

问题4：

安卓的开机打印信息很少（安卓4.4.2），我查看proc/sys/kernel/printk，打印的是4417.源码/lichee/linux-3.4/kernel/printk.c文件中已经定义了#define DEFAULT_CONSOLE_LOGLEVEL 7，为什么编译后还是显示4417，请问你们这个打印信息的等级在那里修改？

问题5、

安卓4.4 init.sun8i.rc这个文件应该在那里修改呢？我修改/device/softwinner/astar-evb30目录下的init.sun8i.rc文件，编译后out目录下的文件并没有修改。是我修改的文件错了吗？

修改init.sun8i.rc这个文件，只要把你要修改的内容那部分全部屏蔽掉，然后在下面重新写一个。
