1.	Follow below steps to download all required sources:
a)	Create the workspace in home directory:
$ mkdir ~/panda_work
$ export PANDA_WORK=~/panda_work
$ mkdir ~/panda_work/android
$ export ANDROID_ROOT=~/panda_work/android

b)	Download the android4.4, it may take some time:
$ cd $ANDROID_ROOT
$ export MANIFEST_REPO=https://android.googlesource.com/platform/manifest
$ export MANIFEST_BRANCH=android-4.4.2_r1
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > repo
$ chmod a+x repo
$ ./repo init -u ${MANIFEST_REPO} -b ${MANIFEST_BRANCH}
$ ./repo sync -f -j4

c)	Download the Binaries for PandaBoard:
$ cd $ANDROID_ROOT
$ wget https://dl.google.com/dl/android/aosp/imgtec-panda-20130603-539d1ac3.tgz
$ tar zxvf imgtec-panda-20130603-539d1ac3.tgz
$ ./extract-imgtec-panda.sh

d)	Add support of PandaBoard in downloaded android 4.4 sources:
$ cd $ANDROID_ROOT
$ git clone https://github.com/sola-dolphin1/sola_device_ti_panda.git -b kitkat device/ti/panda

e)	Download the tool-chain for compiling x-loader, u-boot and kernel:
$ cd $PANDA_WORK
$ git clone https://android.googlesource.com/platform/prebuilt
$ export ARCH=arm
$ export CROSS_COMPILE=$PWD/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

f)	Download the X-loader :
$ cd $PANDA_WORK
$ git clone git://git.omapzoom.org/repo/x-loader.git
$ cd x-loader
$ git checkout -b omap4_dev origin/omap4_dev

g)	Download the U-boot:
$ cd $PANDA_WORK
$ git clone git://git.omapzoom.org/repo/u-boot.git
$ cd u-boot
$ git checkout -b omap4_dev origin/omap4_dev

h)	Download the Kernel:
$ cd $PANDA_WORK
$ git clone https://android.googlesource.com/kernel/omap.git kernel
$ cd kernel
$ git checkout -b android-omap-panda-3.0 origin/android-omap-panda-3.0

2.	Apply required patches (attached in mail):
a)	Apply patch in U-boot 
$ cd u-boot
$ git apply 0001-change-bootarges.patch

b)	Apply Kernel patch:
$ cd $PANDA_WORK
$ cd kernel
$ git apply 0001-panda-jb4.2_kernel.patch

3.	Compile the sources:
a)	Compile X-loader:
$ cd x-loader
$ make omap4430panda_config
$ make ift
$ cp -a MLO $ANDROID_ROOT/device/ti/panda/xloader.bin

b)	Compile U-boot:
$ cd u-boot
$ make omap4430panda_config
$ make 
$ cp -a u-boot.bin $ANDROID_ROOT/device/ti/panda/bootloader.bin

c)	Compile Kernel:
$ cd $PANDA_WORK
$ cd kernel
$ make panda_defconfig
$ make
$ cp -a arch/arm/boot/zImage $ANDROID_ROOT/device/ti/panda/kernel

d)	Compile Android:
$ cd $ANDROID_ROOT
$ source build/envsetup.sh
$ lunch aosp_panda-userdebug
$ make -j4

4.	Now flash the images to Panda-board SD card:
A) Flashing with Fastboot
PS : If flashing for first time 
Make a partition fat32 and copy xloader.bin and bootloader.bin/u-boot.bin to it and boot the board. Connect USB to board and follow below given steps after board prompts "Fastboot mode is entered ..."


i)	 sudo ./out/host/linux-x86/bin/fastboot oem format

ii)  sudo ./out/host/linux-x86/bin/fastboot flash xloader ./device/ti/panda/xloader.bin 

iii) sudo ./out/host/linux-x86/bin/fastboot flash bootloader ./device/ti/panda/bootloader.bin 

iv)  sudo ./out/host/linux-x86/bin/fastboot flash boot ./out/target/product/panda/boot.img 

v)   sudo ./out/host/linux-x86/bin/fastboot flash system ./out/target/product/panda/system.img 

vi)  sudo ./out/host/linux-x86/bin/fastboot flash cache ./out/target/product/panda/cache.img 

vii) sudo ./out/host/linux-x86/bin/fastboot flash userdata ./out/target/product/panda/userdata.img

viii)  sudo ./out/host/linux-x86/bin/fastboot reboot


B)	Format the SD card with script present in /device/ti/panda 
sudo ./mksdcard_pandaboard.sh /dev/sdX $ANDROID_ROOT
