=Build Instructions=

Setting up build environment
From your work directory (where your 27.12.1-P1 folder resides): export YOUR_PATH=`pwd` export PATH=$PATH:/arm-2010q1/bin export MYDROID=${YOUR_PATH}/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 omap4430sdp_config 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 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.x x-load.bin

ES2.x parameter changes according the SOM HS vresion you have, if you have ES HS 2.2 then use ES2.2

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 make ARCH=arm android_4430_defconfig make ARCH=arm uImage 2>&1 |tee $MYDROID/logs/kernel_make.out

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

Building WLAN driver
cd $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux export KERNEL_DIR=${YOUR_PATH}/kernel make ARCH=arm TNETW=1283

Building SoftAP/HotSpot driver
cd $MYDROID/hardware/ti/wlan/wl1283_softAP/platforms/os/linux export KERNEL_DIR=${YOUR_PATH}/kernel make ARCH=arm TNETW=1283

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

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 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 ${YOUR_PATH}/kernel/drivers/misc/ti-st/st_drv.ko $MYDROID/out/target/product/blazetablet/root cp -Rfp ${YOUR_PATH}/kernel/drivers/bluetooth/btwilink.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/hardware/ti/wlan/wl1283_softAP/platforms/os/linux/tiap_drv.ko $MYDROID/out/target/product/blazetablet/system/etc/wifi/softap/ cp -Rfp $MYDROID/out/target/product/blazetablet/root/*. cp -Rfp $MYDROID/out/target/product/blazetablet/system/. cp -Rfp $MYDROID/out/target/product/blazetablet/data/.

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: cd cp -Rfpv GingerBread_L27.12.1-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.

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

Preparing eMMC images
If you wish to boot entirely from eMMC, you will need to modify init.omap4430.rc file to mount eMMC partitions on your system and create the eMMC partition images:

cd $YOUR_PATH mkdir omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/fastboot omap4_emmc_files cp -f $MYDROID/device/ti/blazetablet/gpt.emmc.bin omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/mkbootimg omap4_emmc_files if [ -e ${YOUR_PATH}/27.12.1-P1/u-boot/u-boot.bin ] ; then cp -f ${YOUR_PATH}/27.12.1-P1/u-boot/u-boot.bin omap4_emmc_files cp -f ${YOUR_PATH}/27.12.1-P1/x-loader/MLO omap4_emmc_files cp -f ${YOUR_PATH}/27.12.1-P1/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 omap4_emmc_files cp -f ${YOUR_PATH}/kernel/arch/arm/boot/zImage omap4_emmc_files fi cp -f $MYDROID/device/ti/blazetablet/env.txt omap4_emmc_files

Creating img files:

cd ${MYDROID} find out/target/product/blazetablet -name *.img -exec rm -f {} \; make cp -f ${MYDROID}/out/target/product/blazetablet/*.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 "bootargs" --board omap4 -o boot.img Please note: "bootargs" are defined below (so use in place of bootargs above - in the quotes), bootargs: console=ttyO2,115200n8 rootdelay=2 mem=456M@0x80000000 mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:6M androidboot.console=ttyO2

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}/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 SD boot is not offically supported 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

= 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 (S1-[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 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)]

If you had SD card S1 Dip switch configuration, you can change it now to eMMC conf: SYS_BOOT configuration to boot from eMMC (S1-[1:3] ON, ON, ON)

Now connect the BlazeTablet 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/blazetablet/boot. This is for ES2.2 devices.

cd $YOUR_PATH/omap4_emmc_files cp -f $MYDROID/device/ti/blazetablet/boot/fastboot.sh $YOUR_PATH/omap4_emmc_files sudo ./fastboot.sh --emu  for gp run: sudo ./fastboot.sh --gp

NOTES: Since you are going to execute fastboot.sh from $YOUR_PATH/omap4_emmc_files, you need to make some adjustments to the script before execution.

a) Modify the paths of FASTBOOT and PRODUCT_OUT in the script, like: export FASTBOOT=${FASTBOOT-"./fastboot"} export PRODUCT_OUT=${PRODUCT_OUT-"./"}

b) Make sure the MLO located in $YOUR_PATH/omap4_emmc_files corresponds to your board (being GP or EMU). In the $YOUR_PATH/omap4_emmc_files folder, rename MLO as: %mv MLO MLO_es2.2_emu or %mv MLO MLO_es2.2_gp

c) Modify the paths of MLO and u-boot for "Flashing bootloader.." in the script, like: echo "Flashing bootloader....." $FASTBOOT flash xloader 	./$MLO $FASTBOOT flash bootloader 	./u-boot.bin

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
