[edit] Building U-BOOT
cd $YOUR_PATH/u-boot make distclean (required for rebuild only) make ARCH=arm omap4430sdp_config make 2>&1 |tee $MYDROID/logs/u-boot_make.out
[edit] Building X-LOADER
cd $YOUR_PATH/x-loader make distclean (required for rebuild only) make ARCH=arm blazetablet_config make ift 2>&1 |tee $MYDROID/logs/x-loader_make.out
Signing X-LOADER for EMU devices
The tool for signing x-loader is provided on TI's package. 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 ES2.1 x-load.bin
[edit] Building Kernel
To create kernel uImage you need to add "mkimage" directory path to your "PATH" environment variable:
cd $YOUR_PATH/kernel make ARCH=arm distclean (required for rebuild only) 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 make ARCH=arm modules 2>&1 |tee $MYDROID/logs/kernel_modules.out
[edit] Building WLAN driver
export HOST_PLATFORM=sdc4430 export KERNEL_DIR=$YOUR_PATH/kernel cd $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux make ARCH=arm
[edit] Building Android Filesystem (AFS) with TI Codecs enabled
on step below use the number of cores you have available; i.e. -j4 or -j12:
cd $MYDROID cp -Rfp device/ti/blazetablet/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 BlazeTablet® 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/drivers/staging/ti-st/*.ko $MYDROID/out/target/product/blazetablet/root cp -Rfp $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux/tiwlan_drv.ko $MYDROID/out/target/product/blazetablet/system/etc/wifi cp -Rfp $MYDROID/out/target/product/blazetablet/root/* . cp -Rfp $MYDROID/out/target/product/blazetablet/system/ . cp -Rfp $MYDROID/out/target/product/blazetablet/data/ . cp -Rfp $MYDROID/device/ti/blazetablet/init.omap4sdp.rc init.rc
Since this release won't work without OMAP4 SGX hardware Graphics Accelerator libraries, we include the binaries here
You will need to install the package on your computer, and then copy the binaries to your AFS:
cdcp -Rfpv Froyo_L27.10.2-P1_Graphics/* $YOUR_PATH/myfs
For WLAN, you will also need to get firmware.bin and copy it over $MYDROID/out/target/product/blazetablet/system/etc/wifi. Please contact TI customer representative to gain access to corresponding TI proprietary packages.
[edit] Preparing eMMC images
If you wish to boot entirely from eMMC, you will need to modify init.rc file to mount eMMC partitions on your system and create the eMMC partition images:
cd $MYDROID cp $YOUR_PATH/myfs/init.rc out/target/product/blazetablet/root sed -i -e '/system ro remount/a\ mount ext3 /dev/block/mmcblk0p1 /system\ mount ext3 /dev/block/mmcblk0p1 /system ro remount' \ -e '/data nosuid nodev/a\ mount ext3 /dev/block/mmcblk0p2 /data nosuid nodev' \ -e '/cache nosuid nodev/a\ mount ext3 /dev/block/mmcblk0p3 /cache nosuid nodev' out/target/product/blazetablet/root/init.rc
Now you need to rebuild your Android filesystem; but before you need to erase ramdisk.img file from your 'out' directory:
cd $MYDROID rm -f out/target/product/blazetablet/ramdisk.img make -j4
This build should not take too much time and will re-generate a new ramdisk.img file with the modified init.rc file in it.
After build is done you need to copy the new ramdisk.img file to a new directory where you will store all eMMC-related files for easy location:
cd $YOUR_PATH mkdir omap4_emmc_files cp -f $MYDROID/out/target/product/blazetablet/ramdisk.img omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/fastboot omap4_emmc_files cp -f $MYDROID/device/ti/blazetablet/mbr.bin omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/mkbootimg omap4_emmc_files cp -f u-boot/u-boot.bin omap4_emmc_files cp -f x-loader/MLO omap4_emmc_files cp -f kernel/arch/arm/boot/zImage omap4_emmc_files
Starting L27.10.1, uMulti-2 changed to boot.img it is created with mkbootimg instead of mkimage
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 aaaaaa --board omap4 -o boot.img
Then create system image:
cd $YOUR_PATH/omap4_emmc_files dd if=/dev/zero of=./system.img bs=1048510 count=200 mkfs.ext3 -F system.img -L system mkdir tmp sudo mount -o loop system.img tmp cp -prf $YOUR_PATH/myfs/system/* tmp sudo umount tmp
In a similar fashion create userdata and cache partitions:
cd $YOUR_PATH/omap4_emmc_files dd if=/dev/zero of=./data.img bs=1048510 count=150 mkfs.ext3 -F data.img -L data sudo mount -o loop data.img tmp cp -prf $YOUR_PATH/myfs/data/* tmp sudo umount tmp dd if=/dev/zero of=./cache.img bs=1048510 count=50 mkfs.ext3 -F cache.img -L cache
And finally the environment file with the bootargs and bootcmd information (see 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):(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):
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/kernel/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
Insert your SD card (with u-boot, x-loader and uImage loaded in FAT partition and ) into BlazeTablet SD/MMC card slot, then plug the BlazeTablet 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 BlazeTablet 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
Starting on L27.7.2 release onwards the eMMC partition table changed and the flashing procedure now uses fastboot protocol. Please read carefully the following instructions
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´ll need to format your SD card and load the u-boot, MLO and fastboot file from the image to the boot partition.
To boot using the SD card change your SYS_BOOT configuration (S2-[1:8] OFF, ON, OFF, ON, ON, ON, ON, ON) with the SD card inserted turn your BlazeTablet 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)]

OMAP44XX SDP # fastboot
Fastboot entered...
On a linux machiche were you should have untared the release image run
$ sudo ./fastboot.sh
If this is the first time you boot the device edit the fastboot.sh and uncomment the first line so it creates the master boot partition. This only need to be done the first time you boot the board doing it after that may create a partition conflict. That's why by default the fastboot.sh have this command commented.
Now connect the BlazeTablet micro USB port to your Linux box and go to where the eMMC files are. The first fastboot command will create the Master Boot Record that has the partition table along with other boot information on eMMC and the others will flash the files onto the corresponding eMMC partition
The following part contain detailed information about how fastboot.sh works, to continue booting the board go to the booting part of this guide.
mbr.bin changed for this release, partition table name "mbr" has been renamed to "ptable". Hence mbr.bin needs to be Reflashed
Make sure you boot OS loader from SD, also ensure you have 10.2 u-boot and MLO in the SD.
cd $YOUR_PATH/omap4_emmc_files ./fastboot flash ptable mbr.bin ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin ./fastboot flash environment ./env.txt ./fastboot flash boot ./boot.img ./fastboot flash system ./system.img ./fastboot flash userdata ./data.img ./fastboot flash cache ./cache.img
Once MBR is created you no longer need to flash mbr anymore; only when partition table changes is when we would need to flash mbr again but don't expect changes in the partition table so soon. You can now switch to boot from eMMC.
IMPORTANT: DO NOT ERASE ptable, system, userdata OR cache PARTITIONS. If you want to update these partitions with a new set of eMMC images just use fastboot "flash" commands as described above. For the other partitions you can safely use fastboot "erase" command before updating them:
./fastboot erase xloader ./fastboot erase bootloader ./fastboot erase environment ./fastboot erase boot
Booting
When fastboot has finished disconect the micro USB and power cables from the board. Insert a SD card into BlazeTablet SD/MMC card slot (now only required to store MM files, ideally use a different one than the one used for booting), then plug the BlazeTablet mini USB port to your PC and open a serial terminal (baudrate:115200, no parity, 8 bits), change your SYS_BOOT configuration to boot from eMMC (S2-[1:8] ON, ON, ON, ON, ON, ON, ON, ON) and power your board up and in your terminal window you should be able to see the auto-boot process start in 5 seconds:
* This SYS_BOOT configuration must be kept even when you want to update eMMC binaries set, just keep in mind you must NOT flash mbr.bin file again.

Right after this your BlazeTablet should start booting kernel image and loading the Android filesystem both from BlazeTablet eMMC
[edit] To Install Apps or Copy Files
Installing an App: First give permission to data folder, chmod 777 -R /data To install: adb install -r
Copy Files: To keep files after a reboot or restarting the eMMC it is recommended to copy these files to the sdcard or data folder. adb push/data or adb push /sdcard
