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® board. This step will prepare a directory, called myfs, containing all necessary Android files that you

must include within your SD card.

cd $YOUR_PATH mkdir myfs cd myfs cp -Rfp ${YOUR_PATH}/kernel/android-2.6.35/drivers/staging/ti-st/*.ko $MYDROID/out/target/product/blaze/root cp -Rfp ${YOUR_PATH}/kernel/android-2.6.35/drivers/bluetooth/btwilink.ko $MYDROID/out/target/product/blaze/root cp -Rfp ${YOUR_PATH}/kernel/android-2.6.35/drivers/media/radio/wl128x/fm_v4l2_drv.ko $MYDROID/out/target/product/blaze/root cp -Rfp $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux/tiwlan_drv.ko $MYDROID/out/target/product/blaze/system/etc/wifi/ cp -Rfp $MYDROID/hardware/ti/wlan/wl1283_softAP/platforms/os/linux/tiap_drv.ko $MYDROID/out/target/product/blaze/system/etc/wifi/softap/ cp -ax $MYDROID/device/ti/proprietary-open/graphics/omap4/* $MYDROID/out/target/product/blaze  (To be run if you haven't build the SGX DDK) cp -Rfp $MYDROID/out/target/product/blaze/root/*. cp -Rfp $MYDROID/out/target/product/blaze/system/. cp -Rfp $MYDROID/out/target/product/blaze/data/.

Changing default display resolution on Android

Default LCD density is now set to 240 (was 160 previously by default). If you want to come back to the previous setting to make Android UI look smaller (smaller icons, etc...), comment the following line in system/build.prop
 * 1) ro.sf.lcd_density=240

It is recommended to remove the "critical" setting when the syslink_daemon for ducati is booting. To do this you will need to edit init.omap4430.rc for

eMMC boot or mmc-init.omap4430.rc for SD boot as indicated: service baseimage /system/bin/syslink_daemon.out -f /data/base_image_sys_m3.xem3 /data/base_image_app_m3.xem3 critical (Remove this line) user media group media
 * 1) Load IVA firmware

So it will be: service baseimage /system/bin/syslink_daemon.out -f /data/base_image_sys_m3.xem3 /data/base_image_app_m3.xem3 user media group media
 * 1) Load IVA firmware

Preparing eMMC images for 4430
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 if [ -e ${YOUR_PATH}/27.G.3/u-boot/u-boot.bin ] ; then cp -f ${YOUR_PATH}/27.G.3/u-boot/u-boot.bin omap4_emmc_files cp -f ${YOUR_PATH}/27.G.3/x-loader/MLO_es2.2_gp omap4_emmc_files cp -f ${YOUR_PATH}/27.G.3/kernel/android-2.6.35/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/MLO_es2.2_gp omap4_emmc_files cp -f ${YOUR_PATH}/kernel/android-2.6.35/arch/arm/boot/zImage omap4_emmc_files fi

cp -f /MLO_es2.2_emu omap4_emmc_files

Preparing eMMC images for 4460
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 if [ -e ${YOUR_PATH}/27.G.3/u-boot/u-boot.bin ] ; then cp -f ${YOUR_PATH}/27.G.3/u-boot/u-boot.bin omap4_emmc_files cp -f ${YOUR_PATH}/27.G.3/x-loader/MLO_es1.0_gp omap4_emmc_files cp -f ${YOUR_PATH}/27.G.3/kernel/android-2.6.35/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/MLO_es1.0_gp omap4_emmc_files cp -f ${YOUR_PATH}/kernel/android-2.6.35/arch/arm/boot/zImage omap4_emmc_files fi

cp -f /MLO_es1.0_emu omap4_emmc_files

Creating img files:

cd ${MYDROID} find out/target/product/blaze -name *.img -exec rm -f {} \; make cp -f ${MYDROID}/out/target/product/blaze/*.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 ./mkbootimg --kernel zImage --ramdisk ramdisk.img --base 0x80000000 --cmdline "console=ttyO2,115200n8 rootdelay=2 mem=456M@0x80000000

mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:4M androidboot.console=ttyO2" --board omap4 -o boot.img

Please note: To edit BootArgs you need to create again boot.img with the desired bootargs in --cmdline <"bootargs">

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

And finally the environment file with the bootargs and bootcmd information (see bootargs section)

= Booting Kernel and Android File System from SD card = 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

(Write your changes to the SD Card) Command (m for help): w

(You will see the following output) The partition table has been altered!

Calling ioctl to re-read partition table.

WARNING: If you have created or modified any DOS 6.x partitions, please see the fdisk manual page for additional information. Syncing disks.

Format your partitions typing the following commands (logged as root@ubuntu-box): $ mkfs.vfat -F 32 -n boot /dev/ $ mkfs.ext3 -L android_fs /dev/

There is a shell script that all calculations above automatically; to get it do: $ wget http://cgit.openembedded.org/cgit.cgi/openembedded/plain/contrib/angstrom/omap3-mkcard.sh

Add execution permission: $ chmod +x omap3-mkcard.sh

And you are ready to use it by just typing: $sudo ./omap3-mkcard.sh 

Copying Binaries onto SD Card

Now type the following to mount your SD Card on your Linux box (logged as root@ubuntu-box): $ mkdir /tmp/mmc1 $ mkdir /tmp/mmc2 $ mount /dev/ /tmp/mmc1 $ mount /dev/ /tmp/mmc2

Load the appropriate software to the SD Card (logged as root@ubuntu-box): $ cp $YOUR_PATH/x-loader/MLO /tmp/mmc1  (if you are using EMU or HS device, plese copy signed MLO instead) $ cp $YOUR_PATH/u-boot/u-boot.bin /tmp/mmc1 $ cp ${YOUR_PATH}/27.G.3/kernel/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1 $ cp -Rfp $YOUR_PATH/27.G.3/myfs/* /tmp/mmc2 $ chmod –R 777 /tmp/mmc2/* $ umount /tmp/mmc1 $ umount /tmp/mmc2

Booting SD boot is not offically supported hence SD boot was not validated Insert your SD card (with u-boot, x-loader and uImage loaded in FAT partition and ) into Blaze SD/MMC card slot, then plug the Blaze mini USB port to your PC and open a serial terminal (baudrate:115200, no parity, 8 bits). Power your board up and in your terminal window you should be able to see the ‘New’ u-boot prompt:

“OMAP44XX SDP #”

In your serial terminal define the bootargs and boot as mentioned in the bootarg section.

Right after this your Blaze should start booting using the kernel image and loading the Android filesystem from your SD

= Booting Kernel and Android File System from eMMC = Formatting eMMC

If your are going to use eMMC for the first time, you need to create the appropriate partition table and create a filesystem (format) for each partition. For

this you need to load u-boot from your SD card; for this you need to change your SYS_BOOT configuration (S2-[1:3] OFF, ON, OFF). Use the u-boot.bin

and the x-loader you built for this release; copy them to your "boot" partition of your SD card, turn your Blaze on and press any key on your serial terminal

to stop the auto-boot process.

Now type from you serial terminal (on the u-boot prompt) 'fastboot' and board should be waiting for any fastboot command. You should see something like

this: [Please note this is an older snapshot (so rev numbers you see might be different as compared to below)]

If you had SD card S2 Dip swtich cnfiguration, you can change it now to eMMC conf: SYS_BOOT configuration to boot from eMMC (S2-[1:3] ON, ON,

ON)

Now connect the Blaze 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. Make sure the commands are issued as super user. You can use ./fastboot.sh which is located at

$MYDROID/device/ti/blaze/boot.

These steps are for 4430 ES2.2 devices.

cd $YOUR_PATH/omap4_emmc_files cp -f $MYDROID/device/ti/blaze/boot/fastboot.sh. sed -i 's/${FASTBOOT-".\/..\/..\/..\/..\/out\/host\/linux-x86\/bin\/fastboot"}/.\/fastboot/g' fastboot.sh sed -i 's/${PRODUCT_OUT-".\/"}/./g' fastboot.sh   sed -i 's/.boot\/$MLO/\/$MLO/g' fastboot.sh sed -i 's/.boot\/u-boot.bin/\/u-boot.bin/g' fastboot.sh

if you are flashing 4460 ES1.0, depending on your device run the following: sed -i 's/MLO_es2.2_emu/MLO_es1.0_emu/g' fastboot.sh sed -i 's/MLO_es2.2_gp/MLO_es1.0_gp/g' fastboot.sh

if you are flashing 4430 ES2.1, before executing the script run sed -i 's/MLO_es2.2_emu/MLO_es2.1_emu/g' fastboot.sh sed -i 's/MLO_es2.2_gp/MLO_es2.1_gp/g' fastboot.sh

./fastboot.sh --emu  for gp run: ./fastboot.sh --gp

For your information the script does the following: cd $YOUR_PATH/omap4_emmc_files ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin ./fastboot reboot-bootloader sleep 5 ./fastboot oem format ./fastboot flash boot ./boot.img ./fastboot flash system ./system.img ./fastboot flash userdata ./userdata.img ./fastboot flash cache ./cache.img
