Android (www.android.com) is an open source operating system for mobile devices.
|
||
|
|
This document describes configurations needed to run the Android framework on
|
||
|
|
top of the Linux kernel.
|
||
|
|
|
||
|
|
To see a working defconfig look at msm_defconfig or goldfish_defconfig
|
||
|
|
which can be found at http://android.git.kernel.org in kernel/common.git
|
||
|
|
and kernel/msm.git
|
||
|
|
|
||
|
|
msm_defconfig should work on qualcomm reference design, HTC Magic and G1/ADP1.
|
||
|
|
|
||
|
|
1.1 Required enabled config options
|
||
|
|
-----------------------------------
|
||
|
|
After building a standard defconfig, ensure that these options are enabled in
|
||
|
|
your .config or defconfig if they are not already. Based off the msm_defconfig.
|
||
|
|
You should keep the rest of the default options enabled in the defconfig
|
||
|
|
unless you know what you are doing.
