=Build Instructions=

Setting up build environment
From your work directory (where your 27.IS.2 folder resides): export YOUR_PATH=`pwd` export PATH=$PATH:/arm-2010q1/bin export MYDROID=${YOUR_PATH}/27.IS.2/mydroid mkdir $MYDROID/logs export CROSS_COMPILE=arm-none-linux-gnueabi- export PATH=${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
cd ${YOUR_PATH}/x-loader make distclean make ARCH=arm omap44XXtablet_config #(for Blaze_Tablet) make ARCH=arm omap4430sdp_config #(for Blaze) make ift 2>&1 |tee $MYDROID/logs/x-loader_make.out

mv MLO Blaze_Tablet_GP_ES1.1_MLO #(for Blaze_Tablet) mv MLO Blaze_GP_ES1.1_MLO #(for Blaze)
 * 1) For fastboot.sh flashing script purpouse 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 OMAP4460 ES1.1 x-load.bin

cp MLO Blaze_Tablet_HS_ES1.1_MLO #(For Blaze_Tablet) mv MLO Blaze_HS_ES1.1_MLO #(For Blaze)
 * 1) For fastboot.sh flashing script purposes 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 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
For both WL127x and WL128x the build procedure is as below. 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 compat.ko, cfg80211.ko, mac80211.ko, wl12xx.ko, wl12xx_sdio.ko

Note: It is mandatory to perform WiFi calibration while using ICS binaries for WL1271 devices as descried in http://omappedia.org/wiki/Android_Mac80211#WLAN_Calibration_Instruction

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) or lunch full_blaze-userdebug # (for Blaze)

make clean ;#(required for rebuild only) make -j4 2>&1 |tee $MYDROID/logs/android_make.out

The GFX DDK and Ducati binaries are available within Android within the following repository : device/ti/proprietary-open.git Make sure you are using the RLS27.IS.2.P2_IcecreamSandwich.xml manifest (P2) as this contains fixes so both blaze and blaze_tablet have the correct ducati binaries installed.

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

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/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/

cd $YOUR_PATH mkdir myfs cd myfs 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 cp -f $MYDROID/out/host/linux-x86/bin/fastboot omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/mkbootimg omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/make_ext4fs omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/simg2img omap4_emmc_files if [ -e ${YOUR_PATH}/27.IS.2/u-boot/u-boot.bin ] ; then cp -f ${YOUR_PATH}/27.IS.2/u-boot/u-boot.bin omap4_emmc_files cp -f ${YOUR_PATH}/27.IS.2/x-loader/Blaze_Tablet_GP_ES1.1_MLO omap4_emmc_files #(or Blaze_GP_ES1.1_MLO) cp -f ${YOUR_PATH}/27.IS.2/kernel/android-3.0/arch/arm/boot/zImage omap4_emmc_files else cp -f ${YOUR_PATH}/u-boot/u-boot.bin omap4_emmc_files cp -f ${YOUR_PATH}/x-loader/Blaze_Tablet_GP_ES1.1_MLO omap4_emmc_files #(or Blaze_GP_ES1.1_MLO) cp -f ${YOUR_PATH}/kernel/android-3.0/arch/arm/boot/zImage omap4_emmc_files fi

cp -f /Blaze_Tablet_HS_ES1.1_MLO omap4_emmc_files #(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 This build should not take too much time and will re-generate a new *.img files with the modified init.rc file in it (If you built and installed GFX after

compiling AFS, system.img and data.img will also be updated with the GFX files).

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 $MYDROID/device/ti/support-tools/boot/omap4/umulti2.sh

Now create cache partition: cd $YOUR_PATH/omap4_emmc_files 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. Note: SD Card Boot is not supported in this release.

cd $YOUR_PATH/omap4_emmc_files 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 Fastboot started

When running the fastboot script the command should be issued as super user when run:

./fastboot.sh 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 Fastboot started

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

Formatting SD Card

You will need to format your SD for the Linux file system. Connect your SD memory card reader with memory card inserted to a USB port on your Linux Ubuntu PC. You must login as Super User.

$ su $ fdisk -l

Match the device to the size of your memory card. Look for the /dev/*** device which matches the memory card in the card reader. Use the matching device’s letter prefix in the next command. For example if the device for memory card reader card example was: /dev/sdb1, then use only /dev/sdb in the fdisk command.

Take note of the size in bytes of your SD Card. You will need this to calculate the number of cylinders in a future step.

$ fdisk /dev/sdb (replace sdb with the letter prefix for your device)

(Delete all partitions on the card if they exist) Command (m for help): d Partition number (1-4): 1 Command (m for help): d Selected partition 2

Command (m for help): x

(Change the number of heads, sectors and cylinders on the device) Expert command (m for help): h Number of heads (1-256, default 255): 255 Expert command (m for help): s Number of sectors (1-63, default 63): 63 Expert command (m for help): c Number of cylinders (1-1048576, default 248): 

(Now return to the main menu) Expert command (m for help): r

(Create the first partition) Command (m for help): n Command action e  extended p  primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-248, default 1): 1 Last cylinder or +size or +sizeM or +sizeK (1-248, default 248): +64M

If you plan to use this SD card partition for storing media your can use +1024M assuming a 2+ GB SD card.

(Create the second partition) Command (m for help): n Command action e  extended p  primary partition (1-4) p Partition number (1-4): 2 First cylinder (10-248, default 10): 10 Last cylinder or +size or +sizeM or +sizeK (124-248, default 248): 

(Change the first partition to at FAT32 partition) Command (m for help): t Partition number (1-4): 1 Hex code (type L to list codes): c Changed system type of partition 1 to c (W95 FAT32 (LBA))

(Toggle the bootable flag for partition 1) Command (m for help): a Partition number (1-4): 1

(Print the partition table to confirm your settings) Command (m for help): p

(Sample Output – your output may differ depending on your SD card’s size and brand) Disk /dev/sdb: 2041 MB, 2041577472 bytes 255 heads, 63 sectors/track, 248 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000
