Instructions for "https://android-build.linaro.org/builds/~linaro-android-restricted/armv8-android-fvp-lsk/":https://android-build.linaro.org/builds/~linaro-android-restricted/armv8-android-fvp-lsk/
h2. Prerequisites
To clone the sources you must be able to ssh to git.linaro.org and be part of the big-little-switcher-private group. Contact "Philip Colmer" <philip.colmer@linaro.org> for access requests.
Install build dependencies on Ubuntu:
<pre>
$ sudo add-apt-repository ppa:linaro-maintainers/tools
$ sudo apt-get update
$ sudo apt-get install gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc uboot-mkimage openjdk-7-jdk openjdk-7-jre vim-common python-parted python-yaml wget uuid-dev iasl
</pre>
You can also download linaro android build script(linaro_android_build_cmds.sh) from Downloads section at https://android-build.linaro.org/builds/~linaro-android-restricted/armv8-android-fvp-lsk to do a complete ARMv8 Android build for FVP models from scratch.
h2. Get the source
<pre>
$ curl "https://android.git.linaro.org/gitweb/tools/repo.git/blob_plain/refs/heads/stable:/repo" >repo
$ chmod +x repo
$ ./repo init -u git://android.git.linaro.org/platform/manifest.git -b armv8-linaro -m baseline_manifest.xml
$ ./repo sync # this may take some time
</pre>
h2. Build
<pre>
$ export CPUS=`grep -c processor /proc/cpuinfo`
$ export TARGET_PRODUCT=vexpress
$ export TARGET_BUILD_VARIANT=userdebug
$ . build/envsetup.sh
$ make -j${CPUS} selinuxtarballs
</pre>
h2. Get linaro image tools
Run these commands to get all the dependencies for linaro-image-tools
<pre>
$ sudo add-apt-repository ppa:linaro-maintainers/tools
$ sudo apt-get update
$ sudo apt-get install linaro-image-tools
</pre>
If you're using a "tip" build then we suggest you use the tip of linaro-image-tools from http://git.linaro.org/infrastructure/linaro-image-tools.git
h2. Create binary for ARM FVP Base AEMv8 models
Run linaro image tools
pre. $ linaro-android-media-create --image_file mmc.bin --image_size 2000M --dev vexpress --system system.tar.bz2 --userdata userdata.tar.bz2 --boot boot.tar.bz2
If you're using tip of linaro image tools
pre. $ ./linaro-image-tools/linaro-android-media-create --image_file mmc.bin --image_size 2000M --dev vexpress --system system.tar.bz2 --userdata userdata.tar.bz2 --boot boot.tar.bz2
h2. Extract the preboot files
pre. tar -jxvf boot.tar.bz2
h2. Setup the runtime environment
<pre>
$ export ARMLMD_LICENSE_FILE="8224@localhost"
$ ssh -L 8224:localhost:8224 -L 18224:localhost:18224 -N $USER@flexlm.linaro.org
</pre>
h2. Running the models (verified on FVP Base model build 5502)
<pre>
$ cd boot
$ /path/to/FVP_Base_AEMv8A-AEMv8A/models/Linux64_GCC-4.1/FVP_Base_AEMv8A-AEMv8A \
-C pctl.startup=0.0.0.0 \
-C bp.secure_memory=0 \
-C cluster0.NUM_CORES=1 \
-C cluster1.NUM_CORES=1 \
-C cache_state_modelled=0 \
-C bp.pl011_uart0.untimed_fifos=1 \
-C bp.secureflashloader.fname=bl1.bin \
-C bp.flashloader0.fname=fvp_fip.bin \
-C bp.virtioblockdevice.image_path=mmc.bin
</pre>
h3. Console redirection
To redirect the console open a terminal and run
pre. telnet 127.0.0.1 5000
h3. Set UEFI configuration, update kernel/ramdisk path and bootargs
Stop the UEFI boot process and configure it for FVP models:
<pre>
$ telnet 127.0.0.1 -debug 5000 -e ^z
Telnet escape character is 'b'.
Telnet escape character is '^Z'.
Trying 127.0.0.1...
setsockopt (SO_DEBUG): Permission denied
Connected to 127.0.0.1.
Escape character is '^Z'.

h3. Black screen
The boot screen has been disabled to speed up booting. This means you may not see anything on the CLCD terminal for a while depending on the performance of the machine the model is running on. For example a first boot on a 2 GHz machine with 32 GB of RAM took 20 minutes. Subsequent boots should take approximately half the time to boot.
h2. Run the Android SDK
h3. Attach ADB
ADB on FVP Base models are supported over network. Follow the instructions here https://wiki.linaro.org/Internal/Projects/Juice/SetupNetworkingOnModelsUsingBridges to setup networking and use adb.
You can also run all of the standard Android SDK tools. Learn more at "http://developer.android.com/sdk/index.html":http://developer.android.com/sdk/index.html
