IoT.bzh● Specialized on Embedded & IoT● Contributing to AGL Project

for Renesas● Expertise domains:

– System architecture– Security– Application Framework– Graphics & Multimedia– Middleware– Linux Kernel

● Located in Brittany, France


Agenda

● SDK Explained● Building the SDK in a Docker image● Demo - AGL 1.0 SDK● Future enhancements● Demo - AGL next SDK● Q&A


SDK Explained


Context

● HTML5, native or hybrid applications on top of the AGL BSP for a specific board

● Bypass shortage of Yocto skills– ~ 0.5M embedded developers– ~ 17M web & mobile apps developers

● Heterogeneous environments: for a good adoption, the SDK should work in various environments: Windows, Linux, Mac OS


Proposed Features

● IDE - Integrated Development Environment● Develop source code ● Build for a selected AGL target board

(cross-compiling)● Deploy the software package onto a target

board or an emulator● Remotely run & debug the software

package in the target environment


Proposed architecture


Benefits● Naturally aligned with the BSP

– a SDK container is built after each BSP container, for every snapshot– applications in the SDK are built with the same toolchain as the BSP.

● Stability & Uniformity– a container provides simple, unbiased build environments– independent of the host system

● Ubiquity– a SDK container may run on the Cloud, on-premises, on developers

hosts …● Cost & Time to market

– out-of-the-box solution– applications developed faster and ready earlier

● Long Term Support– re-create the development environment decades after product release


Availability

● Available for AGL Albacore 1.0 on Renesas Porter since January 2016

Building the SDK


Three base components

1: Base Docker image - Debian 8.x

2: AGL Application Development Toolkit

3: IDE - Eclipse


1: SDK Base Docker Image● Based on latest Debian 8.x● Meets the requirements for both Yocto ADT

and Eclipse IDE● XRDP Server, very light desktop environment

(OpenBox)● Extra tools:

– gcc, g++ (x86_64 native toolchain), cmake, ccache, git, ...

– nodejs, gulp, bower (HTML5 development)● Upgradable and expandable:

– this is a genuine Debian image, with “full” comfort– apt-get update && apt-get install <whatever>


2: AGL App Dev Toolkit● produced by bitbake using Yocto/OE tools

and AGL layers

bitbake agl-image-ivi-crosssdk● auto-installable archive, ~400MB● content:

– cross toolchain (gcc, g++, binutils for the target platform)

– C/C++ headers depending on distribution content– static and dynamic libraries– Target sysroot, Native sysroot

● should be built and published in every AGL snapshot/release for all target boards


3: Integrated Dev Environment

● Eclipse IDE is popular and widely spread

● Maintained by Eclipse.org and Codenvy● Many plugins are available, in

particular:– Yocto ADT plugin– TCF (WindRiver) for deployment, access

and remote debug on a target board (even behind firewalls)

● Eclipse Kepler for Yocto 1.7 compatibility


Building SDK in a container

● Instantiate a new SDK base container● Copy and install AGL ADT archive● Install Eclipse IDE and plugins● Finalize environment (XRDP server, user

homescreen, extra tools ...)● Commit the container into a new image


Docker: Publish & Deploy

● Tag the SDK image with unique id:– IMAGE_ID=agl/sdk-porter-snapshot:b141

– docker tag 75293fda2e39 $IMAGE_ID

● Push to Docker hub or private Registry:– docker push $IMAGE_ID

● A developer can then grab and run the image:– docker run -p 3389 --privileged \

-v /sys/fs/cgroup:/sys/fs/cgroup:ro agl/sdk-porter-snapshot:b141


Deploy without Docker Hub

● Tag the SDK image with unique id:– IMAGE_ID=agl/sdk-porter-snapshot:b141

– docker tag 75293fda2e39 $IMAGE_ID

● Export the image to a file and publish it on the web:– docker save $IMAGE_ID | xz -T0 -c >sdk-porter-snapshot_b141.xz

– scp sdk-porter-snapshot_b141.xz www@webserver:/srv/www/htdocs/downloads/

● A developer can then grab and run the image:– curl http://.../sdk-porter-snapshot_b141.xz | docker load

– docker run -p 3389 --privileged \

-v /sys/fs/cgroup:/sys/fs/cgroup:ro agl/sdk-porter-snapshot:b141


Demo: AGL 1.0 SDKfor Renesas Porter board


Renesas Porter Board● R-Car M2 SoC

– ARM Cortex-A15– Dual Core 1.5GHz– Multimedia Engine– GPU PowerVR SGX544MP2

● 2GB DDR3● 2 Flash Mem Chips● Ethernet● Storage: SATA, SD, microSD● Video: Analog In, HDMI Out● Audio: In/Out● USB 2.0● CAN Transceiver


AGL SDK Initialization● Load the SDK Docker image:

● Instantiate a new SDK Container named 'aglsdk':

● Open a new RDP session on localhost:3389

docker pull docker.iot.bzh/agl/snapshot-stable-sdk:1.0

docker run --publish=3389:3389 --detach=true \ --privileged \ --hostname=aglsdk --name=aglsdk \ -v /sys/fs/cgroup:/sys/fs/cgroup:ro \ docker.iot.bzh/agl/snapshot-stable-sdk:1.0

xfreerdp -u devel -p devel -g 1200x700 localhost


Connect through RDP

RDP session starting Eclipse IDE Initial Screen


Build a C/C++ program

Cross-compilation using Yocto & Eclipse


Remote debugging

Remote debugging on Eclipse using SSH and gdbserver


Future Enhancements


Future enhancements

● Use Eclipse Che (next generation IDE)– Web & Containers based– Support for C/C++ and HTML5 apps

● AGL specific plugin for Eclipse can be developed


Eclipse Che Architecture

Next SDK Architecture


Technical Improvements

● Smaller SDK image:– Remove RDP– ADT cleanup

● Target board emulation through Qemu● Solve permission conflicts on shared files

due to lack of UID mapping in Docker


Demo: AGL 2.0 SDK previewbased on Eclipse Che


Building HTML5 Application

● Standard Web and Mobile build environment:– Angular.js, Foundation for Apps

● Build system:– Code optimization, compression– Support Development/Production modes

● Associated browser:– Debugging in Chromium– LiveReload extension


HTML5 Apps

Radio, Annex, Rabbit


Application Framework Design


Eclipse Che: dashboard


Eclipse Che: new project


Eclipse Che: HTML5 workspace


Q&A

Gulf of Morbihan, south of Brittany, France
