=Using the Prebuilt Release Image= The prebuilt release image can be obtained from here. After you download the binaries, follow the flashing instruction from "Flashing eMMC images" section.

=Rebuilding Android from Sources=

Build PC setup
You would need a 64bit Ubuntu machine for building Android file system. You must have sudo permissions on the PC for installing packages


 * Install Pre-requisite packages for building the Android File System

Follow instructions from official Android page here for setting up the packages required for building Android. You would also need to install Java7 for building Lollipop


 * Proxy/Firewall

If you are behind proxy/firewall, workaround it using the instructions in. For installing repo make sure you also export https_proxy environment variable.


 * Install latest repo tool

mkdir ~/bin -p sudo apt-get install curl curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo chmod a+x ~/bin/repo export PATH=~/bin:$PATH


 * Tool Chain for building Kernel and Drivers

The Kernel and Driver sources are built using the Android linux-x86 toolchain for ARM GNU/Linux version. This tool chain can be obtained when you pull the Android code based on the released manifest that will be given.

Android Filesystem Sources
You can get the Android source for this release by doing: cd mkdir -p 6AL.1.1 cd 6AL.1.1 export YOUR_PATH=$PWD mkdir -p mydroid; cd mydroid export MYDROID=$PWD repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b 6AL.x -m RLS_6AL.1.1.xml repo sync

NOTE: If you face issues with "repo sync" command in step above, try again after removing hammerhead-kernel project from manifest. Remove the below mentioned line from $MYDROID/.repo/manifest.xml file 

TI Hardware Accelerated Graphics and MultiMedia Binaries
Multimedia (DCE) and accelerated graphics binaries are part of Android file system build

Copy WLAN Driver (This step is for making wlan driver modules to be part of system.img) cd $OUT/system/lib/modules/ cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/compat/compat.ko. cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/net/wireless/cfg80211.ko. cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/net/mac80211/mac80211.ko. cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/drivers/net/wireless/ti/wl18xx/wl18xx.ko. cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/drivers/net/wireless/ti/wlcore/wlcore.ko. cp -fp ${MYDROID}/hardware/ti/wlan/mac80211/compat_wl18xx/drivers/net/wireless/ti/wlcore/wlcore_sdio.ko.

Rebuild AFS to generate update images cd $MYDROID . build/envsetup.sh lunch full_jacinto6evm-userdebug rm out/target/product/jacinto6evm/*.img rm out/target/product/jacinto6evm/obj/PACKAGING/systemimage_intermediates/system.img make -j2

Preparing eMMC binaries/images
cd $YOUR_PATH mkdir emmc_files cp -v ${MYDROID}/out/target/product/jacinto6evm/*img emmc_files cp -v ${MYDROID}/device/ti/jacinto6evm/fastboot.sh emmc_files cp -v ${MYDROID}/out/host/linux-x86/bin/{simg2img,make_ext4fs,mkbootimg,fastboot,adb} emmc_files cp -v ${YOUR_PATH}/kernel/android-3.14/arch/arm/boot/zImage emmc_files/kernel cp -v ${YOUR_PATH}/kernel/android-3.14/arch/arm/boot/dts/dra7*.dtb emmc_files cp -v ${YOUR_PATH}/u-boot/MLO emmc_files/GP_MLO cp -v ${YOUR_PATH}/u-boot/MLO emmc_files/ cp -v ${YOUR_PATH}/u-boot/u-boot.img emmc_files

=Flashing eMMC images=

The default setup is to flash MLO and u-boot.img to QSPI and remaining binaries (kernel, dtb file and AFS) to emmc.
 * Instructions are same for J6 and J6 Eco EVM
 * For more info on partitions and flashing refer to "QSPI NOR/eMMC partitions" Application note.
 * If you are using pre built binaries and have a J6 Rev D or E board (7" panel) flash dra7-evm-lcd7.dtb file

DIP Switch settings
Required DIP switch settings: This configuration corresponds to the following device boot order: SD &rArr; QSPI_1

Flashing procedure
Hit any key to stop autoboot: 3 U-Boot# fastboot cd $YOUR_PATH/emmc_files sudo ./fastboot.sh
 * Copy u-boot.img and MLO files to an SD card (boot partition) and then boot the target board from this external SD card.
 * Connect a USB cable from the Linux PC to the USB3.0 port on board
 * Power on the board and stop the board at u-boot prompt by interrupting with key press
 * Put the board in fastboot mode by typing in fastboot command
 * On the Linux PC which has the emmc images run the fastboot.sh script to flash the binaries
 * NOTE: After the flashing is done, remove the external SD card and reboot the board.
