h2(#preface). 1. Preface
The ARM software images contained in this released are distributed according to the "EULA":#https://releases.linaro.org/15.04/members/arm/android/images/armv8-android-juno-lsk#tabs-5
This release page describes how to download the source code and binaries, build the source code and install all the binaries on your Juno platform. There are also links below to download Linaro prebuilt binaries.
For a description of the Juno hardware and how to get started with the platform see the "Juno getting started guide":#http://community.arm.com/docs/DOC-8393
For any problems with your Juno system or this software please contact juno-support@arm.com
h2(#sw). 2. Software
This release supports 3 different software stacks which have been validated on the Juno platform. All include board firmware, System Power Controller firmware, ARM Trusted firmware and a choice of UEFI or u-boot loader. The options are:
* LSK - Linaro Stable Kernel (v3.10) + Android LCR
* LSK - Linaro Stable Kernel (v3.10) + OpenEmbedded Filesystem
* Linaro Tracking Kernel (latest) + OpenEmbedded Filesystem
For each option the instructions here use prebuilt binaries for the filesystem.
h3(#pre). 2.1 Prerequisites
* To be run on an Ubuntu 14.04 LTS system
* Preinstall the following packages:
bc
bison
build-essential
curl
flex
g++-multilib
gcc-multilib
genext2fs
git
gperf
iasl
libc6:i386
libstdc++6:i386,
libncurses5:i386
libxml2-utils
make
openjdk-7-jdk
python
python-mako
uuid-dev
wget
zlib1g:i386
zlib1g-dev:i386
zip
* Install Linaro GCC (aarch64 little endian) from "here":#http://releases.linaro.org/14.11/components/toolchain/binaries/aarch64-linux-gnu/gcc-linaro-4.9-2014.11-x86_64_aarch64-linux-gnu.tar.xz
* Install the 'Repo' tool as per "Installing Repo":#https://source.android.com/source/downloading.html. Do not initialize the Repo client
* If necessary, also register for authenticated access by following the instructions in the "Using Authentication" section of "Installing Repo":#https://source.android.com/source/downloading.html
* Configure Git's user.email and user.name attributes before using repo.
h3(#down). 2.2 Downloading the software and binaries
* Create a workspace directory and cd into it
* Use the repo tool to sync all the software GITs
For a LSK kernel:
repo init -u https://git.linaro.org/landing-teams/working/arm/manifest -b juno -m lsk.xml
For the latest tracking kernel:
repo init -u https://git.linaro.org/landing-teams/working/arm/manifest -b juno -m latest.xml
Then in both cases:
repo sync -j8
* Download the filesystem binary image you want to use:
For Android, download juno.img.bz2 from "here":#https://releases.linaro.org/15.04/android/lcr/armv8-android-juno-lsk (accept the EULA to download)
For OE, download your preferred filesystem image from "here":#https://releases.linaro.org/15.04/openembedded/juno-lsk - (called lt-vexpress64-openembedded-<type>-armv8-gcc-<version>.img.gz where <type> is minimal or lamp)
For either case unpack the .img file. Insert a USB stick (minimum 4GB) into your system and run:
sudo dd if=<downloaded file>.img of=/dev/sd<x> (where <x> is the letter corresponding to the USB stick)
h3(#build). 2.3 Building the software
* First edit your <workspace>/build-scripts/variants/juno-oe to make LINUX_COMPILER point at the relative path and prefix to where you installed Linaro GCC
* From the root directory of your workspace execute the following commands to build the software components and package them into an output folder:
* For LSK - Linaro Stable Kernel (v3.10) + Android LCR
./build-scripts/build-all.sh juno-android
./build-scripts/build-all.sh juno-android package
* For LSK - Linaro Stable Kernel (v3.10) + OpenEmbedded Filesystem OR
* For Linaro Tracking Kernel (latest) + OpenEmbedded Filesystem
./build-scripts/build-all.sh juno-oe
./build-scripts/build-all.sh juno-oe package
The build will create binaries for ARM Trusted Firmware, UEFI, u-boot, Linux and a DTB. The Firmware components will then be packaged into a FIP and all the binaries copied under the "output" folder.
Running a different build will overwrite derived objects in the source tree, but will not overwrite the output folder created by the package step.
h3(#install). 2.4 Installing on your Juno
* Copy the NOR flash binaries to your Juno
Connect up the USB configuration port to your build system whereby the NOR flash will be mounted as a new drive For UEFI copy the contents of output/<variant>/uefi to the SOFTWARE folder
For u-boot copy the contents of output/<variant>/uboot to the SOFTWARE folder
Where <variant> is one of juno-android or juno-oe
Insert the USB stick created above into your Juno
Power cycle your Juno and it will run the new software
h3(#prebuilt). 2.4 Installing prebuilt binaries your Juno
If you want to use prebuilt binaries rather than download and build the software as described above, they can be downloaded from:
* "Linaro Stable Kernel (v3.10) + Android LCR":#https://releases.linaro.org/15.04/android/lcr/armv8-android-juno-lsk
* "Linaro Stable Kernel (v3.10) + OpenEmbedded Filesystem":#https://releases.linaro.org/15.04/openembedded/juno-lsk
* "Linaro Tracking Kernel (latest) + OpenEmbedded Filesystem":#https://releases.linaro.org/15.04/openembedded/aarch64
In each case follow the instructions in the Binary Image Installation tab to install
