+# Running AGL on Intel MinnowBoard (and most Intel 64 bits HW)
+
+## Scope
+
+This documentation is aiming at people who want to run Automotive Grade
+Linux (AGL) on Intel Hardware (HW).
+While the reference HW used by AGL project is the Open Source MinnowBoard, this documentation [MinnowBoard wiki](https://minnowboard.org/) can be used to enable most of 64-bit Intel Architecture (IA) platforms using UEFI as boot loader.
+In addition to the MinnowBoard, support for the [upCore & UpSquared boards](http://www.up-board.org/upsquared/) has been added.
+You need to run the 64-bit version of the UEFI bootloader.
+MinnowBoard Max and Turbot as well as Joule are both 64-bit capable.
+
+**Note**: This page is more focused on those who want to create bespoke AGL images and BSPs.
+
+If you are interested in creating ***applications*** to run on AGL, please visit the [Developing Apps for AGL](https://wiki.automotivelinux.org/agl-distro/developer_resources_intel_apps) documentation.
+
+UEFI has evolved a lot recently and you likely want to check that your HW firmware is up-to-date, this is mandatory for both the MinnowBoard-Max and the Joule. Not required on Minnowboard-Turbo and Up boards.

+
+## Where to find an AGL bootable image
+
+### Download a ready made image
+
+AGL provides ready made images for developers.
+You will find them on [AGL Download web site](https://download.automotivelinux.org/AGL/release)
+image are located in YourPreferedRelease/intel-corei7-64/deploy/images/intel-corei7-64/
+Create a bootable SD card with the script [mkefi-agl.sh](https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git;a=blob_plain;f=scripts/mkefi-agl.sh;hb=HEAD)
+check the available options with the -v option. mkefi-agl.sh -v
+
+### Building an AGL image from scratch using Yocto
+
+**Note**: an alternative method for building an image is to use the AGL SDK delivered in a Docker container.
+
+There is currently no SDK dedicated to IA but the SDK provided for the Porter Board can build an IA image without changes (just `aglsetup.sh` needs to call for Intel).
+
+See chapter 2 of [Porter QuickStart](http://iot.bzh/download/public/2016/sdk/AGL-Kickstart-on-Renesas-Porter-board.pdf "wikilink").
+
+#### Download AGL source code
+
+Downloading the AGL sources from the various Git repositories is automated with the `repo` tool. Basic steps to download the AGL source code is described below and for more advanced topics involving the `repo` tool, please refer to the [`repo` documentation](https://source.android.com/source/using-repo.html "wikilink").
+
+To install the `repo` tool:
+
+```bash
+ mkdir -p ~/bin;
+ export PATH=~/bin:$PATH;
+ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo;
+ chmod a+x ~/bin/repo;
+```
+
+#### Configuring for the current *(older)* stable (Electric Eel 5.0.x)
+
+```bash
+ cd AGL-5.0.x;
+ repo init -b eel -m default.xml -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
+```
+
+#### Configuring for master (DD)
+
+```bash
+ cd AGL-master;
+ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo;
+```
+
+Once that you repo is initialised either with the stable or WIP, you need to sync the repo to fetch the various git trees.
+
+#### Downloading the configured AGL source code
+
+```bash
+ repo sync;
+```
+
+#### Building the AGL distro
+
+You are now ready to initialise your Yocto build.
+When running the command:
+
+```bash
+ source meta-agl/scripts/aglsetup.sh -h
+```
+
+You will notice the Intel entries
+
+```bash
+ intel-corei7-64
+ joule
+```
+
+Simply select that entry to replace porter in the -m option.
+**Note:** agl-netboot option is required to create the right initramfs even if you do not boot from a network
+
+```bash
+ source meta-agl/scripts/aglsetup.sh \
+ -m intel-corei7-64 \
+ -b build \
+ agl-devel agl-demo agl-appfw-smack agl-netboot agl-audio-4a-framework
+```
+
+**Note:** use the option "-m joule" when building for a Joule developer Kit target.
+
+Start the build **This can take several hours depending of your CPU and
+internet connection and will required several GB on /tmp as well as on your build directory**
+
+```bash
+ bitbake agl-demo-platform
+```
+
+**Your newly baked disk image (.wic.xz) will be located at**:
+ `tmp/deploy/images/intel-corei7-64/`
+
+##### Alternative: Download a *ready made* image from AGL web site
+
+The Continuous Integration (CI) process from AGL creates and publish daily and stable builds.
+Pointers to both can be found in [AGL supported HW](https://wiki.automotivelinux.org/agl-distro) (see Reference BSP/Intel).
+
+Once you have validated your process you can start to play/work with the snapshot pointer.
+
+Note that snapshot build may not work.
+
+Follow the directory:
+
+`intel-corei7-64/deploy/images/intel-corei7-64/`
+
+and download the file:
+
+`agl-demo-platform-intel-corei7-64.hddimg`
+
+## Create a bootable media
+
+Depending your target HW you will use an USB stick, an SD card or a HDD/SDD.
+The creation process remains the same independently of the selected support.
+It does require to have access to a Linux machine with `sudo` or root password.
+
+### Insert you removable media in the corresponding interface
+
+### Check the device name where the media can be accessed with the command
+
+```bash
+ lsblk
+ # Note that you want the name of the raw device not of a partition on the media
+ #(eg. /dev/sdc or /dev/mmcblk0)
+```
+
+### Download the script `mkefi-agl.sh`
+
+This script is present in the directory meta-agl/scripts from blowfish 2.0.4 : [mkefi-agl.sh](https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git;a=blob_plain;f=scripts/mkefi-agl.sh;hb=HEAD)
+
+Alternatively you can download it from the following Git repo:
+
+[https://github.com/dominig/mkefi-agl.sh](https://github.com/dominig/mkefi-agl.sh)
+
+### check the available options
+
+```bash
+ sh mkefi-agl.sh -v;
+```
+
+### create your media with the command adjusted to your configuration
+
+```bash
+ sudo sh mkefi-agl.sh MyAglImage.hdd /dev/sdX
+ #/dev/sdX is common for USB stick, /dev/mmcblk0 for laptop integrated SD card reader
+```
+
+## Boot the image on the target device
+
+1. Insert the created media with the AGL image in the target device
+
+1. Power on the device
+
+1. Select Change one off boot option (generally F12 key during power up)
+
+1. Select your removable device
+
+1. Let AGL boot
+
+**Note:**: depending on the speed of the removable media, the first boot may not complete, in that case simply reboot the device.
+
+This is quite common with USB2 sticks.
+
+By default the serial console is configured and activated at the rate of 115200 bps.
