Build and Boot AGL Flutter Instrument Cluster demo image made for GSoC¶

0. Prepare Your Build Host¶

• Install the required tools to build an AGL Image. For detailed explanation, check Preparing Your Build host

1. Define Your Top-Level Directory¶

$ export AGL_TOP=$HOME/AGL
$ echo 'export AGL_TOP=$HOME/AGL' >> $HOME/.bashrc
$ mkdir -p $AGL_TOP

2. Download the repo Tool and Set Permissions¶

$ mkdir -p $HOME/bin
$ export PATH=$HOME/bin:$PATH
$ echo 'export PATH=$HOME/bin:$PATH' >> $HOME/.bashrc
$ curl https://storage.googleapis.com/git-repo-downloads/repo > $HOME/bin/repo
$ chmod a+x $HOME/bin/repo

3. Download the AGL Source Files¶

To download the latest master branch AGL files, use the following commands:

$ cd $AGL_TOP
$ mkdir master
$ cd master
$ repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo
$ repo sync

4. Initialize the build environment using aglsetup.sh Script¶

To initialize the build environment, we must use the setup script. This script is available here:

$ $AGL_TOP/master/meta-agl/scripts/aglsetup.sh

$ cd $AGL_TOP
$ source master/meta-agl/scripts/aglsetup.sh -b build-flutter-cluster -m qemux86-64 agl-demo agl-devel

• Here -b is used to specify the build directory and -m is used to specify the target platform.

• Running this script, will create a build directory if it does not exist. Default build directory: $AGL_TOP/master/build-flutter-cluster

• Default target paltform: qemux86-64

** NOTE: Set the API key in local.conf **

• By default navigation will not work, you need to set your openrouteservie API key to the variable OPENROUTE_API_KEY in your local.conf

• It is present at $AGL_TOP/master/build-flutter-cluster/conf/local.conf

• Example: Just add OPENROUTE_API_KEY = "your_openrouteservice_api_key" to the end of local.conf

5. Using BitBake¶

$ cd $AGL_TOP/master/build-flutter-cluster
$ source agl-init-build-env
$ bitbake agl-cluster-demo-platform-flutter

6. Deploying the AGL Demo Image¶

Boot the image using QEMU

$ cd $AGL_TOP/master/build-flutter-cluster
$ source agl-init-build-env
$ runqemu kvm serialstdio slirp publicvnc

6. Run the Graphics¶

To get graphics of the app, you need VNC client like VNC Viewer or Vinagre

• Open the VNC client
• Enter the server address as localhost:0

That's it, you should get something like this:

7. To start navigation widget¶

To get the navigation, you need to use kuksa_viss_client or kuksa_vss_init.py script.

Using inbuilt kuksa_vss_init.py script¶

After running the build, you should get this:

Automotive Grade Linux 13.93.0 qemux86-64 ttyS0

qemux86-64 login:

Login as root

qemux86-64 login: root

root@qemux86-64:~# /usr/sbin/kuksa_vss_init.py
