$ wget http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/exports/TI_Android_GingerBread_2_3_4Sources.tar.gz
$ wget http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/exports/Tools.tar.gz

2. Repo sync with local :

$ cd TI_Android_GingerBread_2_3_4Sources
$ ./.repo/repo/repo sync --local-only

3. Patch latest "PPOWP" to your directory. Refer below 'Patch method'

4. Export envronment path :
export MYDROID=$HOME/TI_Android_GingerBread_2_3_4Sources
export PATH=$MYDROID/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH
export CROSS_COMPILE=arm-eabi-
export ARCH=arm
export PATH=$MYDROID/u-boot/tools:$PATH
export TARGET_PRODUCT=beagleboard
export OMAPES=5.x
 
5. Make u-boot,x-loader,kernel and android :

   a) x-loader
    $ make distclean 
    $ make omap3beagle_config ;
    $ make 2>&1

   b) u-boot
    $ make distclean
    $ make omap3_beagle_config
    $ make

   c) kernel & android
    $ cd $MYDROID
    $ make clean
    $ make TARGET_PRODUCT=beagleboard OMAPES=5.x

6. Copy all the image to a directory

    a) Create a directory
    $ cd $MYDROID/prebuild_images ; mkdir $MYDROID/prebuild_images/Boot_Images ; mkdir MYDROID/prebuild_images/Filesystem

    b) Make & copy rootfs image
    $ sudo $MYDROID/../Tools/mktarball.sh $MYDROID/out/host/linux-x86/bin/fs_get_stats android_rootfs . rootfs rootfs.tar.bz2
    $ cp $MYDROID/out/target/product/beagleboard/rootfs.tar.bz2 $MYDROID/prebuilt_images/Filesystem

    c) Copy kernel image
    $ cp $MYDROID/kernel/arch/arm/boot/uImage $MYDROID/prebuilt_images/Boot_Images
     
    d) Change name of x-load.bin to MLO
    $ cp $MYDROID/../Tools/signGO $MYDROID/x-loader
    $ cd $MYDROID/x-loader
    $ ./signGP $MYDROID/x-loader/x-load.bin  --- The will generate a file "x-load.bin.ift"
    $ mv x-load.bin.ift MLO

    e) Before generate boot script to modify it.
    $ sed -i 's/ttyO0/ttyO2/g' $MYDROID/../Tools/mk-bootscr/mkbootscr 
    $ sed -i 's/128M/512M/g' $MYDROID/../Tools/mk-bootscr/mkbootscr 
    $ sed -i 's/mkimage/.\/mkimage/g' $MYDROID/../Tools/mk-bootscr/mkbootscr                                               
    $ cd $MYDROID/../Tools/mk-bootscr
    $ ./mkbootscr
    $ cp $MYDROID/../Tools/mk-bootscr/boot.scr $MYDROID/prebuilt_images/Boot_Images

    f) Copy u-boot image
    $ cp $MYDROID/u-boot/u-boot.bin $MYDROID/prebuilt_images/Boot_Images

7. Make partition to SD card

    a) Copy script to image directory
    $ cp $MYDROID/../Tools/mk-mmc/mkmmc-android.sh $MYDROID/prebuilt_images
    
    b) Execute script before,prepare your SD card
    $ cd $MYDROID/prebuilt_images
    $ sudo ./mkmmc-android.sh /dev/sdx


Patch method
-------------

Advice to use 'git' patch it,even though can use 'patch' command.
Since the 'patch' can not generate to ".bin" file in your work directory.

Note : use patches before, please move to correspond path to first. Example :

    $ cp panther-board/kernel_path/*.patch  $MYDROID/kernel/

1. Git
        Install git tool first.

        $ sudo apt-get install git

        How to do patch it ? follow up as below :

        $ git apply <patch_name>

        if you want to restore you'r code,can to do it :

        $ git apply -R <patch_name>

        Ignore warring message "trailing whitespace".

2. Patch

        Use general a command 'patch' to patch it :

        $ patch -p1 < <patch_name>

        Please note your path from patch. If you want to restore :

        $ patch -p1 -R < <patch_name>

If you want to verify to SoftAP functions,you must to install "busybox" in you filesystem and then use script to start softap.

Install busybox :

1. Download busybox-1.19.2 for lastest version.

2. Toolchain use arm-2009qx to compile busybox.
