Android Jelly Bean 4.2.2 Devkit Rotating Display of touchscreen ...Help Needed

Hi Nitish,

the way to control the device rotation between ICS and JB changed quite a bit. This property that you are using does not exist anymore. Instead, you need to modify 2 settings into the a database. See the Android documentation:
- developer.android.com/.../Settings.System.html
- developer.android.com/.../Settings.System.html

You basically need to set the ACCELEROMETER_ROTATION to 0 and the USER_ROTATION to 0, 1, 2, 3, ou 4 according to this:
- ROTATION_0 = 0
- ROTATION_90 = 1 // this is what you want here
- ROTATION_180 = 2
- ROTATION_270 = 3

There are different solutions to achieve what you want:

1) create an Android application with android.permission.WRITE_SETTINGS permission, and execute the following code:
Settings.System.putInt(this.contentResolver, Settings.System.ACCELEROMETER_ROTATION, 0);
Settings.System.putInt(this.contentResolver, Settings.System.USER_ROTATION, Surface.ROTATION_90);

2) on the running system: update the settings.db using sqlite:
/system/xbin/sqlite3 /data/data/com.android.providers.settings/databases/settings.db
insert into system (name,value) values('accelerometer_rotation',0);
insert into system (name,value) values('user_rotation',1);
.exit

3) before build, in your device/<your device folder>/ add an overlay onto the framework file: "frameworks/base/packages/SettingsProvider/res/values/defaults.xml" and update this version with the appropriate rotation value using the keys:
- <integer name="def_user_rotation">1</integer>
- <bool name="def_accelerometer_rotation">false</bool>

Hi Nitish,

Which the two attached patches you should be able to have Android rotated as you want.
It introduces a new variable ro.sf.hwrotation , which can be set to 0, 90, 180, or 270.
0001-Set-rotation-to-90-by-default.patch is a patch for device/ti/am335xevm_sk/
0001-Added-ro.sf.hwrotation-support.patch is a path for frameworks/base/

The only missing part is the boot screen, we should look into the kernel for that.
As for you other questions :
1. The screen resolution is defined in the kernel in the mx23evk_video_modes structure (kernel/arch/arm/mach-mxs/mach-mx23evk.c).
But you should not have to modify it. The touchscreen doesn't follow the screen resolution, it has its own resolution.

2. To enable the Navigation Bar, modify device/ti/am335xevm_sk/init.am335xevm.rc and add, in the init section:
setprop lcd.landscape true

And modify the  overlay/frameworks/base/core/res/res/values/config.xml file:
<bool name="config_showNavigationBar">true</bool>

3. Have you tried to do make TARGET_PRODUCT=beaglebone -j4 ?
