Configuring BeagleBoard's S1 User Button as Home Button in Android
I am using BeagleBoard C4 and Android 2.3.4 GingerBread.
And I have an 4.3" OLED for GUI. Both of them works fine. But I want to ask a question.
How can I configure S1 User Button (on BeagleBoard C4) as Home Button in Android ?
I always have to use a mouse for browsing menu.
You can try to use adb tu simulate keyboard, with the command "input keyevent".
Take a look here:
You can modify the key code specified to user button as KEY_HOME in board specific file..
Edit the kernel/arch/arm/mach-omap2/board-omap3beagle.c file and Modify the user button entry in structure static struct gpio_keys_button gpio_buttons. In user button entry change the .code variable to KEY_HOME. Rebuild the kernel and use it.
This might help you

Thanks for answers. Faisal's method is works great.
Faisal , Where can I find the character codes(KEY_HOME, KEY_MENU etc.) ?
I know only KEY_HOME and KEY_BACK. And tested both of them.
Check this header file <android-source>/bionic/libc/kernel/common/linux/input.h line no 87 for more key codes.
Thanks for all your help. It was very helpful.
I am planning to add HOME and BACK button using Expansion GPIO header.
