Panda5AJ.1.5.1 Release Notes

= Introduction =

These Release Notes provide instructions for: and
 * Testing the release using a pre-built binary image which can be loaded onto eMMC on uEVM board
 * Rebuilding the Android binary image from the Android sources

Both sets of instructions make use of binary components to enable hardware acceleration for Graphics and Multimedia.

This software release has been developed and verified in the following software and hardware environment.

OS Kernel: Linux® 3.4 Android:  Android JellyBean 4.2.2 Toolchain: Andriod linux-x86 toolchain arm-eabi-4.6 Reference hardware platforms: TI OMAP5 5432 uEVM ES2.0 (Panda5) Build Host OS: Ubuntu Daily Build OMAP5 uEVM Version: OMAP5_JB_panda5_mr1 build 128 Secure Boot: Customers needing access to Mshield DK lite for HS device should contact their TI representatives to get access.  NOTE: This release is not backward compatible with OMAP5432 ES1.0 silicon


 * uEVMs built with ES1.0 Silicon are labeled UEVM5432x-00-yy-zz
 * uEVMs built with ES2.0 Silicon are labeled UEVM5432x-02-yy-zz

=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 image" section.

=Rebuilding Android from Sources=

Build PC setup
You would need a 64bit 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

The following commands will install the correct packages to your PC:

Ubuntu 10.04 sudo apt-get install git-core flex bison gperf libesd0-dev zip libwxgtk2.6-dev zlib1g-dev build-essential tofrodos x-dev sudo apt-get install lib32readline5-dev libstdc++6 lib32z1 lib32z1-dev ia32-libs g++-multilib libx11-dev libncurses5-dev sudo apt-get install uboot-mkimage libxml2-utils

Ubuntu 12.04 sudo apt-get install git-core flex bison gperf libesd0-dev zip libwxgtk2.8-dev zlib1g-dev build-essential tofrodos sudo apt-get install lib32readline6-dev libstdc++6 lib32z1 lib32z1-dev ia32-libs g++-multilib libx11-dev libncurses5-dev sudo apt-get install uboot-mkimage libxml2-utils

For more up to date information on initializing build environment for Android, refer to official Android page here


 * Install Java SE 6 JDK from Oracle

http://www.oracle.com/technetwork/java/javase/downloads/index.html


 * 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. export https_proxy= eg: http://local.proxyserver.com:80


 * 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

If you do not have sudo rights to your machine, contact your System Administrator for assistance.


 * 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 5AJ.1.5.1 cd 5AJ.1.5.1 export YOUR_PATH=$PWD mkdir -p mydroid; cd mydroid export MYDROID=`pwd` repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b 5AJ.x -m RLS_panda5AJ.1.5.1.xml repo sync

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

Building usbboot
This is for creating the emmc boot

cd ${YOUR_PATH}/usbboot export CROSS_COMPILE=${MYDROID}/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- make MACH=omap5 BOARD=omap5uevm clean make MACH=omap5 BOARD=omap5uevm

Building Kernel
Follow the steps below to build kernel image.

cd ${YOUR_PATH}/kernel/android-3.4 export CROSS_COMPILE=${MYDROID}/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi- make ARCH=arm mrproper make ARCH=arm android_omap_defconfig make ARCH=arm uImage modules

Building Android Filesystem (AFS)
cd $MYDROID . build/envsetup.sh lunch 25 #(specific lunch target: full_omap5panda-userdebug) make -j2 clean make -j2

Building TI WLAN Drivers

Copy Kernel Image cd $MYDROID cp -v ${YOUR_PATH}/kernel/android-3.4/arch/arm/boot/zImage device/ti/panda5/kernel

Rebuild AFS to generate update images cd $MYDROID . build/envsetup.sh lunch 25 #(specific lunch target: full_omap5panda-userdebug) rm out/target/product/panda5/*img rm out/target/product/panda5/obj/PACKAGING/systemimage_intermediates/system.img make -j2

Preparing eMMC binaries/images
cd $YOUR_PATH mkdir emmc_files cp -v ${MYDROID}/out/target/product/panda5/*img emmc_files cp -v ${MYDROID}/device/ti/omap5sevm/boot/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-3.4/arch/arm/boot/zImage emmc_files/kernel cp -v ${YOUR_PATH}/usbboot/out/omap5uevm/omap5uevm_GP_ES2.0_MLO emmc_files cp -v ${YOUR_PATH}/usbboot/out/omap5uevm/usbboot emmc_files

=Flashing eMMC images=

This is done using usbboot and fastboot tool. usbboot is used to put the OMAP5 uEVM board in fastboot mode and fastboot is used to flash the images to emmc.

Follow the steps below to flash the binaries to emmc of the board:

(Refer here for DIP switch location)

Required switch settings on the Panda5 board to enable eMMC boot. 3  2   1   0   OFF OFF OFF OFF

1. Connect your USB3 cable from the target to your flashing station, the power supply, & the micro usb cable using a terminal or screen (for screen the command is: screen /dev/ttyUSB0 115200)

2. Make sure the board is powered OFF

3. Start usbbboot in fastboot mode:

sudo ./usbboot -f When running this command you will see: usbboot -f: starting in fastboot mode waiting for device...

4. Power up your board

From the terminal you should see something similar to this saying the device is in fastboot mode: r1Texas Instruments Inc Bootloader 1.1.0-jenkins-OMAP5_usbboot-102^0 Build Info: Apr 20 2012 - 05:01:26 Entering fastboot mode... From the command prompt where you ran the usbboot command you should see something similar to this below: reading ASIC ID   CHIP: 5430 IDEN: cfd7d499ed40beab470795a5cfbc5707807b4b6a MPKH: 351edf8f4d739d50f7449a6d3d3d983d6220974836f039c752dae7226bb19955 CRC0: 06e92275 CRC1: 3894aaf5 device is ED/HD (EMU/HS) sending 2ndstage to target... f0030002 waiting for 2ndstage response...   received 2ndstage response...

5. Run your fastboot.sh script sudo ./fastboot.sh      This will flash the binaries into the emmc on the Panda board.

6. Now reset the board and let it boot up.
