### For fastboot.sh flashing script purpose rename MLO: ####
mv MLO MLO_es1.0_emu   or
mv MLO MLO_es1.1_emu

[edit] Building Kernel

Note: If you are building for a GP device (4430 or 4460) 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-2.6.35
make ARCH=arm distclean
make ARCH=arm android_4430_defconfig
make ARCH=arm uImage 2>&1 |tee $MYDROID/logs/kernel_make.out

[edit] Building Kernel modules

cd ${YOUR_PATH}/kernel/android-2.6.35
make ARCH=arm modules 2>&1 |tee $MYDROID/logs/kernel_modules.out

[edit] Building WLAN driver

cd $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux
export KERNEL_DIR=${YOUR_PATH}/kernel/android-2.6.35
make ARCH=arm TNETW=1283

[edit] Building SoftAP/HotSpot driver

cd $MYDROID/hardware/ti/wlan/wl1283_softAP/platforms/os/linux
export KERNEL_DIR=${YOUR_PATH}/kernel/android-2.6.35
make ARCH=arm TNETW=1283

[edit] Building Android Filesystem (AFS) with TI Codecs enabled

If you are running Ubuntu 11.10+ you will need to make the following modifications:

In frameworks/base/libs/utils/Android.mk

  Change line 60: 
  LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)

  To: 
  LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive 

In build/core/combo/HOST_linux-x86.mk

  Change line 61:
  HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
  To:
  HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0


On step below use the number of cores you have available; i.e. -j4 or -j12

cd $MYDROID
source build/envsetup.sh
cp -Rfp device/ti/blaze/buildspec.mk.default buildspec.mk
make clean ;#(required for rebuild only)
make -j4 2>&1 |tee $MYDROID/logs/android_make.out

[edit] 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

[edit] 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

#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:

#Load IVA firmware
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

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

[edit] 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.5/u-boot/u-boot.bin ] ; then 
  cp -f ${YOUR_PATH}/27.G.5/u-boot/u-boot.bin omap4_emmc_files
  cp -f ${YOUR_PATH}/27.G.5/x-loader/MLO_es2.2_gp omap4_emmc_files
  cp -f ${YOUR_PATH}/27.G.5/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 <your_signing_path>/MLO_es2.2_emu omap4_emmc_files


[edit] 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.5/u-boot/u-boot.bin ] ; then 
  cp -f ${YOUR_PATH}/27.G.5/u-boot/u-boot.bin omap4_emmc_files
  cp -f ${YOUR_PATH}/27.G.5/x-loader/MLO_es1.1_gp omap4_emmc_files
  cp -f ${YOUR_PATH}/27.G.5/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_es1.1_gp omap4_emmc_files
  cp -f ${YOUR_PATH}/kernel/android-2.6.35/arch/arm/boot/zImage omap4_emmc_files
fi

cp -f <your_signing_path>/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=448M@0x80000000 

mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:8M 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)
Please see the Note for an update to the bootargs with information on disabling OPP-SB in the bootargs section.

[edit] 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): <You must calculate the number of cylinders for your SD card.  To do this, use the following formula:  

new_cylinders = (Size in bytes from your fdisk –l command)/8225280
Drop any fractional values and enter the whole number in this command.
Use this number all the steps that refer to the number of cylinders>

(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): <use the cylinder value you calculated earlier>  

(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

Syncing disks.

Format your partitions typing the following commands (logged as root@ubuntu-box):
$ mkfs.vfat -F 32 -n boot /dev/<your device’s first partition’s name – see the print output from the previous step> 
$ mkfs.ext3 -L android_fs /dev/<your device’s second partition’s name – see the print output from the previous step> 

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 <your_device (e.g. /dev/sdb)>

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/<your device’s first partition’s name> /tmp/mmc1
$ mount /dev/<your device’s second partition’s name> /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}/kernel/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1
$ cp -Rfp $YOUR_PATH/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

[edit] 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

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

Booting

Power your board up and in your terminal window you should be able to see the auto-boot process start in 3 seconds:

[edit] New Fastboot Script Available

There is a new fastboot script that could be used in place of the current script.
The new script will detect the type of device you have on your board.
Location of the new script that you could copy over the same location as given above:

mydroid\device\ti\support-tools\boot\omap4\fastboot.sh 

This script requires a change in the MLO naming convention given in the steps above when using the older fastboot script
Here is the format that would be used for the MLO name below:

${product}_${cputype}_${cpurev}_MLO
example:
Blaze_EMU_ES2.2_MLO

Running the script would be similar to the old script only you would only need to run ./fastboot.sh gingerbread

[edit] Bootargs

L27.G.5 SD card booting is not offically supported, init.rc and init.omap4430.rc need to be modified as follows:

NOTE: It is mandatory to use the bootarg listed below to disable OPP-SB if the final product is targeting 4460-1.2GHz or 4430-1GHz. Otherwise OPP-SB will be automatically enable if the silicon is detected to support it. The added item: opp_sb_off is added. Note: It is possible that silicons supporting OPP-SB (4460-1.5GHz, or 4430-1.2GHz) are delivered in place of non spin-binned silicons (4460-1.2GHz or

4430-1GHz).

init.rc
on post-fs

   # once everything is setup, no need to modify /
   mount rootfs rootfs / rw remount 

init.omap4430.rc
on fs

   #mount ext4 /dev/block/platform/mmci-omap-hs.1/by-name/system /system wait ro
   #mount ext4 /dev/block/platform/mmci-omap-hs.1/by-name/userdata /data wait noatime nosuid nodev
   #mount ext4 /dev/block/platform/mmci-omap-hs.1/by-name/cache /cache wait noatime nosuid nodev


Example of SD card bootargs similar to the eMMC bootargs given in the BoardConfig.mk file.

  setenv bootargs androidboot.console=ttyO2 console=ttyO2,115200n8 mem=448M@0x80000000 mem=512M@0xA0000000 root=/dev/mmcblk1p2 rw rootdelay=2 init=/init vram="10M" omapfb.vram="0:8M" 
  setenv bootcmd 'mmcinit 0; fatload mmc 0 0x80000000 uImage;bootm 80000000'
  saveenv
  run bootcmd

Example of bootargs using "opp_sb_off"

 setenv bootargs androidboot.console=ttyO2 console=ttyO2,115200n8 mem=448M@0x80000000 mem=512M@0xA0000000 root=/dev/mmcblk1p2 rw rootdelay=2 init=/init vram="10M" omapfb.vram="0:8M" opp_sb_off

"The env.txt and sd_card_env.txt files is no longer used to set the bootargs."

eMMC bootargs

The reference eMMC bootargs are present in

device/ti/blaze/BoardConfig.mk

[http://git.omapzoom.org/?p=device/ti/blaze.git;a=blob;f=BoardConfig.mk;h=3725e9845aa4942d5c6d90f7fd8eb8bd951096a2;hb=d41915850533ab3f43a8

120449834b6be9914642] file, in BOARD_KERNEL_CMDLINE variable.


Right after this your Blaze should start booting kernel image and loading the Android filesystem both from Blaze eMMC
In order to issue commands, it is necessary to type “su -“ on the console.
