=Build Instructions=

Setting up build environment
From your work directory (where your 4AJ.2.1 folder resides): export YOUR_PATH=`pwd` export PATH=$PATH:/arm-2010q1/bin export MYDROID=${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 omap4430panda_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 omap4430panda_config make 2>&1 |tee $MYDROID/logs/u-boot_make.out

Building Kernel
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 $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx export KERNEL_DIR=${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
Extract the source code from the tarball if you haven't yet

cd $MYDROID/device/ti/proprietary-open/omap4/sgx_src tar xzf eurasia_km.tgz

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_120.ko and omaplfb_sgx540_120.ko. These modules are pushed into the /system/lib/modules directory on the system image.

Note that you need to add DISPLAY_CONTROLLER_COMPONENT := dc_omapfb3_linux in eurasia_km/eurasiacon/build/linux2/omap4430_android/Makefile to generate omaplfb_sgx540_120.ko

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_wl12xx/compat/compat.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/net/wireless/cfg80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/net/mac80211/mac80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/drivers/net/wireless/wl12xx/wl12xx.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/drivers/net/wireless/wl12xx/wl12xx_sdio.ko system/lib/modules/

cp $MYDROID/out/target/product/$BOARD_TYPE/target/kbuild/omaplfb_sgx540_120.ko system/lib/modules/ cp $MYDROID/out/target/product/$BOARD_TYPE/target/kbuild/pvrsrvkm_sgx540_120.ko system/lib/modules/

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

First time flashing on SD
If there is no u-boot on your board, 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 (Pandaboard).


 * 1) fastboot

You should see a message such as:

"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

For Formatting the SD Card:

See Android Build SD Configuration page

Not first time flashing on SD
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 (Pandaboard) by keeping the USER button press.

You should see a message such as:

"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.
