1）sys_config.fex中配置如下：
配置VGA 1024x768输出
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 4
screen0_output_mode = 4
screen1_output_type = 1
screen1_output_mode = 4
2)请把sys_config.fex中的fb0_scaler_mode_enable = 1改为fb0_scaler_mode_enable = 0；
3)android/system/core/init/init.c console_init_action 函数注释掉这一行 //init_initdisplay();
4）android\frameworks\base\services\java\com\android\server \system\SystemServer.java
中对热插拔检测和输出模式的控制全部屏蔽掉
5）android\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\policy\DisplayController.java
中控制显示输出的策略模式由mDispHotPolicy = new HomletHotPlug()改成mDispHotPolicy = new StatusBarPadHotPlug()
6）设置中切换HDMI
android/device/softwinner/common/packages/TvdSettings/src/com/android/settings/DisplaySettings.java
switchDispMode函数
- if (displayManager.getDisplayOutputType(0) != item.mOutputType
- || displayManager.getDisplayOutputFormat(0) != item.mFormat) {
+ if (displayManager.getDisplayOutputType(1) != item.mOutputType
+ || displayManager.getDisplayOutputFormat(1) != item.mFormat) {
// displayManager.setDisplayOutputType(0, item.mOutputType,
// item.mFormat);
- displayManager.setDisplayParameter(0, item.mOutputType,
+ displayManager.setDisplayParameter(1, item.mOutputType,
item.mFormat);
+ //displayManager
+ // .setDisplayMode(DisplayManagerAw.DISPLAY_MODE_SINGLE_FB_GPU);
displayManager
- .setDisplayMode(DisplayManagerAw.DISPLAY_MODE_SINGLE_FB_GPU);
+ .setDisplayMode(DisplayManagerAw.DISPLAY_MODE_DUALSAME);
// 设置音频输出模式
