Introduction
This software has been tested in the following software and hardware environment:
OS Kernel: Linux® 3.0
Android: Android IcecreamSandwich 4.0.4(MR1.1)
Toolchain: CodeSourcery compiler version Sourcery G++ Lite 2010q1-202 for ARM GNU/Linux
Reference hardware platforms: TI OMAP4 4430/60 Pandaboard and Pandaboard ES
Build Host OS: Ubuntu
Tools & Dependency packages
Pre-requisite packages for building the Android Filesystem (Note: This is with reference to Ubuntu 12.04 64-bit). Ubuntu 64-bit is required for the cross-compilation of Android Ice Cream Sandwich Filesystem.
If you are behind a firewall, you will have to set-up firewall using the instructions in [1].
The following commands will install the correct packages to your server:
sudo apt-get install git-core flex bison gperf libesd0-dev zip libwxgtk2.6-dev zlib1g-dev build-essential tofrodos sudo apt-get install lib32readline5-dev libstdc++6 lib32z1 lib32z1-dev ia32-libs g++-multilib libx11-dev lib32ncurses5-dev
The following commands will install the host compilers needed in your server:
sudo apt-get install gcc-4.4 gcc-4.4-multilib g++-4.4 g++-4.4-multilib cd /usr/bin sudo ln -sf gcc-4.4 gcc sudo ln -sf g++-4.4 g++
Add the partner repositories and install the JDK:
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner" sudo apt-get update sudo apt-get install sun-java6-jdk
Install repo tool:
mkdir ~/bin -p sudo apt-get install curl curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo chmod a+x ~/bin/repo export PATH=~/bin:$PATH
If you do not have sudo rights to your machine, contact your System Administrator for assistance.
Tool Chain for building Kernel and Drivers
The Kernel and Driver sources are built using Sourcery G++ Lite 2010q1-202 for ARM GNU/Linux version (This particular version is needed for the AFS to work properly).
This tool chain can be obtained from [2].

Build Instructions
Setting up build environment
From your work directory (where your 4AI.1.4 folder resides):
export YOUR_PATH=`pwd`
export PATH=$PATH:<toolchain_parent_dir>/arm-2010q1/bin
export MYDROID=${YOUR_PATH}/mydroid
mkdir $MYDROID/logs
export CROSS_COMPILE=arm-none-linux-gnueabi-
export PATH=${YOUR_PATH}/u-boot/tools:$PATH
Building X-LOADER
cd ${YOUR_PATH}/x-loader
make distclean
make ARCH=arm omap44XXpanda_config
make ift 2>&1 |tee $MYDROID/logs/x-loader_make.out
Building U-BOOT
cd ${YOUR_PATH}/u-boot
make distclean
make ARCH=arm omap44XXpanda_config
make 2>&1 |tee $MYDROID/logs/u-boot_make.out
Building Kernel
Note: If you are building for a GP device it is recommended not to build the SMC kernel driver.
To create kernel uImage you need to add "mkimage" directory path to your "PATH" environment variable:
cd ${YOUR_PATH}/kernel/android-3.0
make ARCH=arm distclean
make ARCH=arm panda_defconfig
make ARCH=arm uImage 2>&1 |tee $MYDROID/logs/kernel_make.out
Building Kernel modules
cd ${YOUR_PATH}/kernel/android-3.0
make ARCH=arm modules 2>&1 |tee $MYDROID/logs/kernel_modules.out
Building WLAN driver
cd $MYDROID/hardware/ti/wlan/mac80211/compat
export KERNEL_DIR=${YOUR_PATH}/kernel/android-3.0
export KLIB=${KERNEL_DIR}
export KLIB_BUILD=${KERNEL_DIR}
make ARCH=arm
The above step will produce the following kernel WLAN modules: compat.ko, cfg80211.ko, mac80211.ko, wl12xx.ko and wl12xx_sdio.ko. These modules are pushed into the /system/lib/modules directory on the system image.
Building Android Filesystem (AFS) with TI Codecs enabled
In the make step below use the number of cores you have available; i.e. -j4 (for 4 cores) or -j12 (for 12 cores)
cd $MYDROID source build/envsetup.sh lunch full_panda-eng make clean ;#(required for rebuild only) make -j4 2>&1 |tee $MYDROID/logs/android_make.out
Building AFS with Android Codecs
This release was not verified with Android codecs.
Building SGX driver
cd $MYDROID/device/ti/proprietary-open/omap4/sgx/src/eurasia_km/eurasiacon/build/linux2/omap4430_android
export KERNELDIR=${YOUR_PATH}/kernel/android-3.0
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- TARGET_PRODUCT="blaze_tablet" BUILD=release TARGET_SGX=540 PLATFORM_VERSION=4.0
The above step will produce the following kernel SGX modules: pvrsrvkm_sgx540_112.ko and omaplfb_sgx540_112.ko. These modules are pushed into the /system/lib/modules directory on the system image.
Preparing Android binaries
The following binaries maybe are not required by the Panda board.
export BOARD_TYPE="panda" cd $MYDROID/out/target/product/$BOARD_TYPE mkdir -p system/lib/modules cp $MYDROID/hardware/ti/wlan/mac80211/compat/compat/compat.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat/net/wireless/cfg80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat/net/mac80211/mac80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat/drivers/net/wireless/wl12xx/wl12xx.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat/drivers/net/wireless/wl12xx/wl12xx_sdio.ko system/lib/modules/ cp target/kbuild/omaplfb_sgx540_120.ko system/lib/modules/ cp target/kbuild/pvrsrvkm_sgx540_120.ko system/lib/modules/
Updating Ducati
For hardware accelerated video playback and camera usage you have to use proper Ducati binary.
Preparing images
cd $YOUR_PATH
mkdir omap4_sd_files_$BOARD_TYPE
cd omap4_sd_files_$BOARD_TYPE
cp -f $MYDROID/out/host/linux-x86/bin/fastboot .
cp -f $MYDROID/out/host/linux-x86/bin/mkbootimg .
cp -f $MYDROID/out/host/linux-x86/bin/simg2img .
cp -f $MYDROID/out/host/linux-x86/bin/make_ext4fs .
cp -f ${YOUR_PATH}/x-loader/MLO .
cp -f ${YOUR_PATH}/u-boot/u-boot.bin .
cp -f ${YOUR_PATH}/kernel/android-3.0/arch/arm/boot/zImage .
Creating img files:
cd ${MYDROID}
find out/target/product/$BOARD_TYPE -name *.img -exec rm -f {} \;
make
cp -f ${MYDROID}/out/target/product/$BOARD_TYPE/*.img $YOUR_PATH/omap4_sd_files_$BOARD_TYPE
This build should not take too much time and will re-generate a new *.img files.
Now from this new directory we will create the SD images which will be flashed using fastboot protocol (described later). First create boot.img image using kernel image we copied previously:
cd $YOUR_PATH/omap4_sd_files_$BOARD_TYPE $MYDROID/device/ti/support-tools/boot/omap4/umulti2.sh
Now create cache partition:
cd $YOUR_PATH/omap4_sd_files_$BOARD_TYPE dd if=/dev/zero of=./cache.img bs=1048510 count=128 mkfs.ext4 -F cache.img -L cache
Flashing the OMAP4 Hardware
After the SD files are available you then can use the fastboot to upload binaries to your Panda or Panda ES.
Connect the Panda or Panda ES mini USB port to your Linux machine and go to where the SD files are. Previous partitions created will be deleted and SD will be flashed with new u-boot and MLO. You need to boot the board and start fastboot server on the target (OMAP4 board).
# fastboot
You should see a message such as:
"Fastboot started..." or "Fastboot entered..."
When running the fastboot the command should be issued as super user then run:
sudo ./fastboot flash xloader MLO sudo ./fastboot flash bootloader u-boot.bin sudo ./fastboot flash boot boot.img sudo ./fastboot flash system system.img sudo ./fastboot flash cache cache.img sudo ./fastboot flash userdata userdata.img sudo ./fastboot reboot
Panda board will boot up on its own with the new image in a few minutes. Until the user interface is ready for use, please avoid interrupting it by pressing any keys etc. This will detect your board and flash the images to the board.
First time flashing on SD
If there is no u-boot on your board's, you will have to boot using SD card. Copy u-boot.bin and MLO files to an SD card (boot partition) and then boot the target board from this external SD card. Once you boot the board, start fastboot server on the target (OMAP4 board).
# fastboot
You should see a message such as:
"Fastboot started..." or "Fastboot entered..."
Now from the PC execute following commands to flash MLO and u-boot to SD
sudo ./fastboot oem format sudo ./fastboot flash xloader ./MLO sudo ./fastboot flash bootloader ./u-boot.bin sudo ./fastboot reboot
This will create several partitions on your SD card that has specific proposes for the Panda board
