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 AGL Software Development Kit Feb 23, 2016 2
Agenda ● SDK Explained ● Building the SDK in a Docker image ● Demo - AGL 1.0 SDK ● Future enhancements ● Demo - AGL next SDK ● Q&A AGL Software Development Kit Feb 23, 2016 3
SDK Explained AGL Software Development Kit Feb 23, 2016 4
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 AGL Software Development Kit Feb 23, 2016 5
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 AGL Software Development Kit Feb 23, 2016 6
Proposed architecture AGL Software Development Kit Feb 23, 2016 7
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 AGL Software Development Kit Feb 23, 2016 8
Availability ● Available for AGL Albacore 1.0 on Renesas Porter since January 2016 http://iot.bzh/download/public/2016/sdk/ AGL Software Development Kit Feb 23, 2016 9
Building the SDK AGL Software Development Kit Feb 23, 2016 10
Three base components 1: Base Docker image - Debian 8.x 2: AGL Application Development Toolkit 3: IDE - Eclipse AGL Software Development Kit Feb 23, 2016 11
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> AGL Software Development Kit Feb 23, 2016 12
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 AGL Software Development Kit Feb 23, 2016 13
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 AGL Software Development Kit Feb 23, 2016 14
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 AGL Software Development Kit Feb 23, 2016 15
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 AGL Software Development Kit Feb 23, 2016 16
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 AGL Software Development Kit Feb 23, 2016 17
Demo: AGL 1.0 SDK for Renesas Porter board AGL Software Development Kit Feb 23, 2016 18
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 Software Development Kit Feb 23, 2016 19
AGL SDK Initialization ● Load the SDK Docker image: docker pull docker.iot.bzh/agl/snapshot-stable-sdk:1.0 ● Instantiate a new SDK Container named ' aglsdk ': 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 ● Open a new RDP session on localhost:3389 xfreerdp -u devel -p devel -g 1200x700 localhost AGL Software Development Kit Feb 23, 2016 20
