[edit] Build Instructions
[edit] Setting up build environment
From your work directory (where your 27.11.1 folder resides):
export YOUR_PATH=`pwd` export PATH=$PATH:/arm-2010q1/bin export MYDROID=${YOUR_PATH}/27.11.1/mydroid mkdir $MYDROID/logs export CROSS_COMPILE=arm-none-linux-gnueabi- export PATH=${YOUR_PATH}/u-boot/tools:${PATH}
[edit] 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
[edit] Building X-LOADER
cd ${YOUR_PATH}/x-loader
make distclean
make ARCH=arm omap4430sdp_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 the use ES2.2
[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
[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
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/ .
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
Copy the WLAN related files to the Android file system
Place the file tiwlan_drv.ko to system/etc/wifi :
$ cd $MYDROID/hardware/ti/wlan/wl1283/platforms/os/linux $ cp tiwlan_drv.ko $MYDROID/out/target/product/blaze/system/etc/wifi
Another file, firmware.bin is also required but this must be obtained from the package OPBU_Linux_27.11.1_WLAN_Firmware_BT_Scripts.zip previously downloaded.
$ cd $MYDROID/out/target/product/blaze/system/etc/wifi $ cp $YOUR_PATH/27.11.1/WLAN_firmware/firmware.bin . $ chmod 777 $MYDROID/out/target/product/blaze/system/etc/wifi/firmware.bin
[edit] Preparing eMMC 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/blaze/gpt.emmc.bin omap4_emmc_files
cp -f $MYDROID/out/host/linux-x86/bin/mkbootimg omap4_emmc_files
if [ -e ${YOUR_PATH}/27.11.1/u-boot/u-boot.bin ] ; then
cp -f ${YOUR_PATH}/27.11.1/u-boot/u-boot.bin omap4_emmc_files
cp -f ${YOUR_PATH}/27.11.1/x-loader/MLO omap4_emmc_files
cp -f ${YOUR_PATH}/27.11.1/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/android-2.6.35/arch/arm/boot/zImage omap4_emmc_files
fi
cp -f $MYDROID/device/ti/blaze/env.txt 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 aaaaaa --board omap4 -o boot.img
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)
[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}/27-GB-ENG-1/kernel/android-2.6.35/arch/arm/boot/uImage /tmp/mmc1
$ cp -Rfp $YOUR_PATH/27.10.1/myfs/* /tmp/mmc2
$ chmod –R 777 /tmp/mmc2/*
$ umount /tmp/mmc1
$ umount /tmp/mmc2
Booting
SD boot is not officially 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 this: [Please note this is an older snapshot (so rev numbers you see might be different as compared to below)]
-- OMAP 4 PPA release 1.0.0 -- Reset reason = 00030181 Texas Instruments X-Loader 1.41 (Feb 25 2011 - 22:30:29) Starting OS Bootloader from EMMC ... U-Boot 1.1.4-gbf5e493e (Feb 25 2011 - 22:30:11) Load address: 0x80e80000 DRAM: 1024 MB Flash: 0 kB In: serial Out: serial Err: serial Net: KS8851SNL Hit any key to stop autoboot: 0 OMAP44XX SDP # fastboot Fastboot entered...
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.
cd $YOUR_PATH/omap4_emmc_files ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin
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)
Power Cycle the Board now and restart fastboot client on board
./fastboot oem format ./fastboot flash xloader ./MLO ./fastboot flash bootloader ./u-boot.bin ./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:
-- OMAP 4 PPA release 1.0.0 -- Reset reason = 00030181 Texas Instruments X-Loader 1.41 (Feb 25 2011 - 22:30:29) Starting OS Bootloader from EMMC ...

Boot Arguments:
setenv bootargs console=ttyO2,115200n8 rootdelay=2 mem=456M@0x80000000 mem=512M@0xA0000000 init=/init vram="10M" omapfb.vram="0:4M" Environment size: 223/131068 bytes
To continue booting just type 'boot' and the boot process will start.
[edit] Bootargs
L27.11.1 SD card booting is not officially supported, init.rc and init.omap4430.rc need to bbe modified as follows:
on post-fs # once everything is setup, no need to modify / mount rootfs rootfs / rw remount
The sd card bootargs are present in device/ti/blaze/sd_card_env.txt file
eMMC bootargs given in env.txt
The eMMC bootargs are present in device/ti/blaze/env.txt file
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.
