4AJ.2.5 OMAP4-Panda Jelly Bean Release Notes

This is not official release notes, just community work. So there is not warranty of any kind. Texas Instruments is not responsible for supporting these notes, it is up to the community. Feel free to use this instructions under your own risk being aware that if you face any issue you have to fix it by yourself

= Warning! = Document now is almost done All generic build issue and basic feature work problems please send to a.beregovenko@ti.com or lolandypanda AT GMAIL

= Introduction = This software has been tested in the following software and hardware environment:

OS Kernel: Linux® 3.4 Android:  Android JellyBean 4.2.2 Parent TI release Android JB 4AJ.2.5 Toolchain: Andriod linux-x86 toolchain arm-eabi-4.6 Reference hardware platforms: TI OMAP4 4460 Pandaboard ES Build Host OS: Ubuntu 12.04 LTS x86_64

= Current status =
 * Device is booting up to UI
 * HDMI connection: works
 * DVI connection: works
 * USB Host: works
 * Mouse connected to USB works
 * Ethernet: not done yet
 * Audio/Video playback: not done yet
 * WiFi/Bluetooth: not done yet

= Tools & Dependency packages =

Pre-requisite packages for building the Android Filesystem (Note: This is with reference to Ubuntu 12.04 64-bit). Ubuntu 64-bit is required for the cross-compilation of Android JellyBean Filesystem.

The following commands will install the correct packages to your server: sudo apt-get install git-core flex bison gperf libesd0-dev zip libwxgtk2.6-dev zlib1g-dev build-essential tofrodos sudo apt-get install lib32readline6-dev libstdc++6 lib32z1 lib32z1-dev ia32-libs g++-multilib libx11-dev lib32ncurses5-dev

Add the partner repositories and install the Oracle/Sun JDK:

Please find proper guide somewhere in Google

Install repo tool: mkdir ~/bin -p sudo apt-get install curl curl https://dl-ssl.google.com/dl/googlesource/git-repo/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 Andriod linux-x86 toolchain arm-eabi-4.6 (This particular version is needed for the AFS to work properly).

It is already inside Android source tree.

= Setting up environment = From your work directory: cd  mkdir -p 4AJ.2.5-panda; cd 4AJ.2.5-panda export YOUR_PATH=`pwd` mkdir -p mydroid cd mydroid export MYDROID=`pwd`

= Downloading Release Software = To obtain Android Filesystem Sources follow: cd ${MYDROID} repo init -u git://git.omapzoom.org/platform/omapmanifest.git -b 27.x -m RLS4AJ.2.5_JellyBean.xml repo sync

To obtain Kernel & Driver Sources follow: cd ${YOUR_PATH} git clone git://git.omapzoom.org/kernel/omap.git kernel/android-3.4 cd kernel/android-3.4 git checkout origin/p-android-omap-3.4

xloader and bootloader are located in device/ti/panda as precompiled binaries

= Patching for Pandaboard Support =

Patching KERNEL
cd ${YOUR_PATH}/kernel/android-3.4

No more additional patches are needed. But you could find something usefull for you in this patch: http://review.omapzoom.org/#/c/32424/

Patching AFS
HWComposer (workaround) cd $MYDROID/hardware/ti/omap4xxx git fetch http://review.omapzoom.org/platform/hardware/ti/omap4xxx refs/changes/42/33142/1 && git cherry-pick FETCH_HEAD

= Build Instructions =

Setting up build environment
cd ${YOUR_PATH} export PATH=$PATH:${MYDROID}/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 mkdir $MYDROID/logs export CROSS_COMPILE=arm-eabi-

Building Kernel
To create kernel uImage you need to add "mkimage" directory path to your "PATH" environment variable: cd ${YOUR_PATH}/kernel/android-3.4 make ARCH=arm distclean make ARCH=arm android_omap_defconfig make ARCH=arm 2>&1 |tee $MYDROID/logs/kernel_make.out

Building Kernel modules
cd ${YOUR_PATH}/kernel/android-3.4 make ARCH=arm modules 2>&1 |tee $MYDROID/logs/kernel_modules.out

Building WLAN driver
cd $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx export KERNEL_DIR=${YOUR_PATH}/kernel/android-3.4 export KLIB=${KERNEL_DIR} export KLIB_BUILD=${KERNEL_DIR} make ARCH=arm

The above step will produce the following kernel WLAN modules: compat.ko, cfg80211.ko, mac80211.ko, wl12xx.ko and wl12xx_sdio.ko. These modules are pushed into the /system/lib/modules directory on the system image.

Building Android Filesystem (AFS)
In the make step below use the number of cores you have available; i.e. -j4 (for 4 cores) or -j12 (for 12 cores) cd $MYDROID source build/envsetup.sh lunch full_panda-userdebug make -j4 2>&1 |tee $MYDROID/logs/android_make.out

Building SGX driver
Extract the source code from the tarball if you haven't yet

cd $MYDROID/device/ti/proprietary-open/omap4/sgx_src tar xzf eurasia_km.tgz cd eurasia_km/eurasiacon/build/linux2/omap4430_android export KERNELDIR=${YOUR_PATH}/kernel/android-3.4 make ARCH=arm CROSS_COMPILE=arm-eabi- TARGET_PRODUCT="blaze_tablet" BUILD=release TARGET_SGX=540 PLATFORM_VERSION=4.0

The above step will produce the following kernel SGX modules: pvrsrvkm_sgx540_120.ko and omaplfb_sgx540_120.ko. These modules are pushed into the /system/lib/modules directory on the system image.

Note that you need to add DISPLAY_CONTROLLER_COMPONENT := dc_omapfb3_linux in eurasia_km/eurasiacon/build/linux2/omap4430_android/Makefile to generate omaplfb_sgx540_120.ko

Preparing Android binaries
NOT VERIFIED YET!!!!

The following binaries maybe are not required by the Panda board.

export BOARD_TYPE="panda" cd $MYDROID/out/target/product/$BOARD_TYPE mkdir -p system/lib/modules cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/compat/compat.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/net/wireless/cfg80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/net/mac80211/mac80211.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/drivers/net/wireless/wl12xx/wl12xx.ko system/lib/modules/ cp $MYDROID/hardware/ti/wlan/mac80211/compat_wl12xx/drivers/net/wireless/wl12xx/wl12xx_sdio.ko system/lib/modules/ cp $MYDROID/out/target/product/$BOARD_TYPE/target/kbuild/omaplfb_sgx540_120.ko system/lib/modules/ cp $MYDROID/out/target/product/$BOARD_TYPE/target/kbuild/pvrsrvkm_sgx540_120.ko system/lib/modules/

Flashing board (with SD card inserted)
You should stay at $MYDROID directory when doing any of following operation.

If this is first time booting up or your SD card is blank, then you need to do initial steps. With no SD card inserted, plug USB first, then the power cord, and load fastboot over USB: device/ti/panda/usbboot device/ti/panda/bootloader.bin

Once in fastboot, insert and initialize an SD card (4GB or greater): fastboot oem format fastboot flash xloader device/ti/panda/xloader.bin fastboot flash bootloader device/ti/panda/bootloader.bin

Then, when you finish building Android File System, you could flash it: fastboot erase cache fastboot flash userdata fastboot flashall

Not first time flashing on SD
After the SD files are available you then can use the fastboot to upload binaries to your Panda or Panda ES.

Connect the Panda or Panda ES mini USB port to your Linux machine and go to where the SD files are. Previous partitions created will be deleted and SD will be flashed with new bootloader and xloader. You need to boot the board and start fastboot server on the target (Pandaboard) by keeping the USER button press.
