Hello,

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.

Thanks.

Best.

Hi,

You can try to use adb tu simulate keyboard, with the command "input keyevent".

Take a look here:

Hi,

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.

Thanks,

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.

Hi,

Check this header file <android-source>/bionic/libc/kernel/common/linux/input.h line no 87 for more key codes.

Hi Faisal,

Thanks for all your help. It was very helpful.

I am planning to add HOME and BACK button using Expansion GPIO header.
