=Build Instructions=

Setting up build environment
From your work directory (where your 4AJ.2.1 directory resides): export YOUR_PATH=`pwd` export MYDROID=${YOUR_PATH}/mydroid export PATH=$PATH:${MYDROID}/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/ mkdir ${MYDROID}/logs export CROSS_COMPILE=${MYDROID}/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- export PATH=${YOUR_PATH}/u-boot/tools:$PATH

Building U-BOOT
cd ${YOUR_PATH}/u-boot make distclean make ARCH=arm omap44XXtablet_config (for Blaze_Tablet) make ARCH=arm omap4430sdp_config (for Blaze) make 2>&1 |tee ${MYDROID}/logs/u-boot_make.out

Building X-LOADER for OMAP4470
cd ${YOUR_PATH}/x-loader make distclean make ARCH=arm omap44XXtablet_config (for Blaze_Tablet) make ARCH=arm omap44XXsdp_config (for Blaze) make ift 2>&1 |tee ${MYDROID}/logs/x-loader_make.out mv MLO Blaze_Tablet_OMAP4470_GP_ES1.0_MLO (for Tablet)
 * 1) For fastboot.sh flashing script needs to rename MLO: ####

Signing X-LOADER for HS devices

The tool for signing x-loader is provided on TI's package, (MShield). Please contact TI customer representative to get access to this tool.

cd ${YOUR_PATH}/mshield-dk cp -f ${YOUR_PATH}/x-loader/x-load.bin. ./generate_MLO OMAP4470 ES1.0 x-load.bin

cp MLO Blaze_Tablet_OMAP4470_HS_ES1.0_MLO #(For Blaze_Tablet)
 * 1) For fastboot.sh flashing script needs to rename MLO: ####

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 ${YOUR_PATH}/kernel/android-3.0 make ARCH=arm distclean make ARCH=arm blaze_defconfig make -j$(egrep '^processor' /proc/cpuinfo | wc -l) 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 flashed image.

Building BTFM driver
cd ${MYDROID}/hardware/ti/wpan/bluetooth-compat export KERNEL_DIR=${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 BTFM modules: compat.ko, btwilink.ko, bnep.ko, hidp.ko, rfcomm.ko, bluetooth.ko. These modules are pushed into the /system/lib/modules directory on the flashed 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

Now depending on your platform use either: lunch blaze_tablet-userdebug # (for Blaze Tablet) lunch full_blaze-userdebug   # (for Blaze)

make clean ;#(required for clean rebuild only) make -j$(egrep '^processor' /proc/cpuinfo | wc -l) 2>&1 |tee ${MYDROID}/logs/android_make.out

Building AFS with Android Codecs
This release was not verified with Android codecs. Camera based applications need TI proprietary drivers. Please contact TI customer representative to get access to proprietary sources

Building Ducati
Appropriate Ducati binary can be found on Android: Working with pre-built binaries page.

Preparing Android binaries
The following binaries are required by the Blaze Tablet® board. This step will prepare a directory, called myfs, containing all necessary Android files that you

must include within your SD card.

export BOARD_TYPE="blaze_tablet" #or "blaze" depending on your board type

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}/hardware/ti/wpan/bluetooth-compat/drivers/bluetooth/btwilink.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/net/bluetooth/hidp/hidp.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/net/bluetooth/bluetooth.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/net/bluetooth/rfcomm/rfcomm.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/net/bluetooth/bnep/bnep.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/compat/sch_codel.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/compat/compat.ko system/lib/modules/ cp ${MYDROID}/hardware/ti/wpan/bluetooth-compat/compat/sch_fq_codel.ko system/lib/modules/

cd ${YOUR_PATH} mkdir myfs_${BOARD_TYPE} cd myfs_${BOARD_TYPE} cp -Rfp ${MYDROID}/out/target/product/${BOARD_TYPE}/root/*. cp -Rfp ${MYDROID}/out/target/product/${BOARD_TYPE}/system/. cp -Rfp ${MYDROID}/out/target/product/${BOARD_TYPE}/data/.

Preparing eMMC images
cd ${YOUR_PATH} mkdir omap4_emmc_files_${BOARD_TYPE} cd omap4_emmc_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}/u-boot/u-boot.bin. cp -f ${YOUR_PATH}/x-loader/Blaze_Tablet_OMAP4470_GP_ES1.0_MLO. #(or Blaze_GP_ES1.1_MLO) cp -f ${YOUR_PATH}/kernel/android-3.0/arch/arm/boot/zImage.

cp -f ${YOUR_PATH}/mshield-dk/Blaze_Tablet_OMAP4470_HS_ES1.0_MLO. #(or Blaze_HS_ES1.1_MLO)

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 ${YOUR_PATH}/omap4_emmc_files_${BOARD_TYPE} This build should not take too much time and will re-generate a new *.img files with the modified init.rc file in it

Now from this new directory we will create the eMMC images which will be flashed using fastboot protocol (described later). First create boot.img image

using kernel image we copied previously:

cd ${YOUR_PATH}/omap4_emmc_files_${BOARD_TYPE} ./mkbootimg --kernel zImage --ramdisk ramdisk.img --base 0x80000000 --board omap4 -o boot.img

Or for HSIC-modified Tablet2 ONLY use: ./mkbootimg --kernel zImage --ramdisk ramdisk.img --base 0x80000000 --cmdline "omap4_tablet_uses_hsic" --board omap4 -o boot.img

Now create cache partition: cd ${YOUR_PATH}/omap4_emmc_files_${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 emmc files are available you then can use the fastboot.sh script to upload binaries to your Blaze or Blaze_Tablet. You will need to copy the fastboot.sh script to the location of the eMMC files.

cd ${YOUR_PATH}/omap4_emmc_files_${BOARD_TYPE} cp ${MYDROID}/device/ti/${BOARD_TYPE}/boot/fastboot.sh.

sed -i 's/${FASTBOOT-".\/..\/..\/..\/..\/out\/host\/linux-x86\/bin\/fastboot"}/.\/fastboot/g' fastboot.sh sed -i 's/${PRODUCT_OUT-".\/"}/.\//g' fastboot.sh Connect the Blaze or Blaze_Tablet micro USB port to your Linux box and go to where the eMMC files are. Previous partitions created will be deleted and eMMC 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 script the command should be issued as super user then run:

./fastboot.sh

Blaze Tablet 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 eMMC If there is no u-boot on your board's eMMC, 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 using the following SYSBOOT switch settings to boot from external SD card: 01011101

For Blaze & Blaze_Tablet board: Switch S2-(1:8): OFF ON OFF ON ON ON OFF ON

Note: S8-(6:1) corresponds to SYSBOOT[5:0] in TRM. (ON=0, OFF=1)

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 eMMC ./fastboot oem format ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin

Now change the following SYSBOOT switch settings to boot out of EMMC: 11111101 whenever the board is restarted.

For Blaze & Blaze_Tablet board: Switch S2-(1:8): ON ON ON ON ON ON OFF ON
