For previous board revisions with OMAP4 ES1 600MHz, the configuration should be changed as described below:
cd $YOUR_PATH/x-loader make distclean make ARCH=arm omap4430sdp_MPU_600MHz_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/27.8.2/mshield-dk cp -f $YOUR_PATH/x-loader/x-load.bin . ./generate_MLO 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/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

export HOST_PLATFORM=sdc4430 export KERNEL_DIR=$YOUR_PATH/kernel/android-2.6.35 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/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 $MYDROID/out/target/product/blaze/root/* . cp -Rfp $MYDROID/out/target/product/blaze/system/ . cp -Rfp $MYDROID/out/target/product/blaze/data/ . cp -Rfp $MYDROID/device/ti/blaze/init.omap4sdp.rc init.rc
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
[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/blaze/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/blaze/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/blaze/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/blaze/ramdisk.img omap4_emmc_files cp -f $MYDROID/out/host/linux-x86/bin/fastboot omap4_emmc_files cp -f $MYDROID/device/ti/blaze/mbr.bin omap4_emmc_files cp -f u-boot/tools/mkimage omap4_emmc_files cp -f u-boot/u-boot.bin omap4_emmc_files cp -f x-loader/MLO omap4_emmc_files cp -f kernel/android-2.6.35/arch/arm/boot/zImage omap4_emmc_files
Now from this new directory we will create the eMMC images which will be flashed using fastboot protocol (described later). First create uMulti-2 image using kernel image we copied previously:
cd $YOUR_PATH/omap4_emmc_files ./mkimage -A arm -O linux -T multi -C none -a 0x80008000 -e 0x80008000 -n 'Linux-2.6.35' -d ./zImage:./ramdisk.img uMulti-2
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:
cd $YOUR_PATH/omap4_emmc_files echo "bootdelay=5 bootargs=console=ttyO2,115200n8 rootdelay=2 mem=458M@0x80000000 mem=512M@0xA0000000 init=/init vram="10M" omapfb.vram="0:4M" bootcmd=mmcinit 1;mmc 1 read 0x1000 0x81000000 0x500000;bootm 81000000 loadaddr=81000000" > env.txt
[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/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1 $ cp -Rfp $YOUR_PATH/27.8.2/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 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 following:
setenv bootargs 'console=ttyO2,115200n8 root=/dev/mmcblk1p2 rw rootdelay=2 mem=458M@0x80000000 mem=512M@0xA0000000 init=/init vram="10M" omapfb.vram="0:4M"'
now type this:
mmcinit 0; fatload mmc 0 0x80000000 uImage; bootm 0x80000000
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
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 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)]

OMAP44XX SDP # fastboot
Disconnect USB cable to finish fastboot..
Now connect the Blaze 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:
cd $YOUR_PATH/omap4_emmc_files ./fastboot flash mbr mbr.bin ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin ./fastboot flash environment ./env.txt ./fastboot flash kernel ./uMulti-2 ./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 mbr, 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 kernel
Booting
Insert your SD card into Blaze SD/MMC card slot (now only required to store MM files), then plug the Blaze mini USB port to your PC and open a serial terminal (baudrate:115200, no parity, 8 bits). Disconnect the micro USB cable if connected to Blaze, change your SYS_BOOT configuration to boot from eMMC (S2-[1:3] 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.
