A useful tool when developing an Automotive Infotainment is a screen to view the User Interface. Recently work has been done to support the official Raspberry Pi 2 7" touch screen, as seen here: raspberry-pi-7-touchscreen-display.
If you build automotive infotainment systems, you know that the integration of hardware and software is a key differentiation. In building the GDP we don't have the resources for custom designed hardware so instead we use COTS or common off the shelf technologies. In fact the GDP supports a number of peripherals almost entirely by contributors.
The RPi touchscreen has required a bit of work to get it to work with the GDP, namely drivers in the RPi. Leon Anavi as well as GDP maintainers worked to bring in the needed software and configuration which inevitably led to upstream. Once an open source driver was brought into Linux mainline, the next step has been ensuring that the Graphical tools used by GENIVI, namely Wayland and the Wayland IVI Extension, work on the screen.
While continued discussion is happening on using the screen with GDP 11, it should be ready for everyday use with both the Raspberry Pi 2 and 3. Use the links I've provided to follow along with the collaboration with many parts of our community as we continue to support widely available and popular hardware running the GDP.
The GENIVI Alliance is publishing a new release candidate, GDP 11 RC2, to improve the stability of the GENIVI Development Platform (GDP) base system while increasing the number of boards on which the GDP is available. The GDP 11 RC2 includes a number of bug fixes, improvements across the system and more stable ports to several development boards. GENIVI has decided to delay the full GDP 11 release to allow for the addition of a significant feature enhancement in the form of a new user interface and application launcher.
In order to enhance the user experience and to ease adding new applications to the GDP, the GENIVI Graphics Team has provided a brand new user experience which is being integrated into the GDP RC2. This significant feature enhancement will be highlighted at the upcoming GENIVI All Member Meeting (AMM) and will include a GENIVI-branded GUI and configurable application launcher. The updated GDP containing this new user experience will receive additional testing to gain the stability needed for a full release after the AMM.
GDP RC2 includes the latest bug fixes from meta-ivi along with a variety of other bug fixes and small improvements across the system with more stable ports to the development boards listed below. There is also a port to QEMU for those who want to take a quick look at what GDP base system is today.
Intel Minnowboard MAX
Raspberry Pi2 and 3
Qualcomm Dragonboard 410c
Those with Yocto knowledge can build this second release candidate from scratch from the GDP Master, where Renesas Porter and Silk are also supported. Other links of interest are:

The GENIVI Alliance appreciates all member and community efforts testing the GDP 11 RC2 and will soon announce a final release candidate with the new user interface for testing.
I recently pushed Genivi 11 support for the Renesas R-Car Gen 2 boards to github.
The branch is a WIP but actually feels very close to a release candidate.
The support is based on the same Yocto BSP v1.10 release used for Genivi 10 and there are no changes to the BSP components.
Changes were limited to adoptions to the krogoth (YP 2.1) branches used by the Genivi Yocto Baseline and of course meta-ivi 11.
Functionally the Poky meta implementation of libdrm is now used.
In summary there have been the following major changes:-
- Support gtk+3 v3.18.8 used in YP 2.1
- Support systemd v299 used in YP 2.1
- Support gst 1.6.x used in YP 2.1 when h/w acceleration is disabled.
- Support mesa 11.x used in YP 2.1. Update configuration (disable libgbm) to fix do_populate_sysroot() error
- Fix omx-user-module QA issue in do_populate_sysroot() related to .la files
- No longer use Renesas libdrm fork
- Fix build error related to linux-libc-headers
- Drop ncurses bbappend as functionality now upstream
- Drop unused gcc 4.8 bbappend
For those who like a graphical diff compared to Genivi 10 you can find a Github compare here.
The following sections provide some more detail including a migration guide.
General information about building Genivi 11 Miranda for the Renesas R-Car SoCs, including build instructions for the Genivi Yocto Baseline and links to GDP can be found in the Renesas Genivi 11 page.
Migration Guide / Behavior changes
- No changes to the BSP components.
See the Genivi 10to be reminded of some functional improvements in the previous release.
The update has been successfully tested with Genivi Yocto Baseline 11 M-02 and the GDP Master RC-1 release for Genivi 11.
Pull request #44 is pending for GDP-11 RC-1 to align the GDP Master branch with this release. The GDP Maintainers tell me they are about to merge it.
Earlier in July GENIVI received configuration for the GENIVI Development platform to run on another popular development board. This time it was Qualcomm’s Dragon Board. This board uses the Qualcomm Snapdragon 400 processor and includes things like bluetooth and GPS and seems quite well suited to running automotive software. I'm including a screen shot below from GitHub showing how Changhyeok Bae and Tom Pollard spun the new board up. Since GENIVI uses build-from-source build tools, namely Yocto and Baserock, we're able quickly port GDP to new hardware as long as there is a fairly recent kernel available for the hardware.
We look forward to more silicon joining the stable and a warm welcome to the Dragon board!
The GENIVI Alliance is happy to announce immediate availability of the first release candidate (RC1) of the GENIVI Development Platform, GDP 11. To provide the highest possible quality of final release, the GDP Delivery Team is calling upon the GENIVI community and others interested in Open Source software for automotive to test the GDP 11 RC1, prior to final release in the next few weeks.
GDP RC1 includes ports to QEMU, MinnowBoard MAX (compatible with the new Minowboard Turbot) and Raspberry Pi 2 and 3. This first candidate brings several improvements from the latest stable Yocto release 2.1.1 including:
- the latest meta-ivi pre-release M-0.2 published last week (Yocto and Baserock versions)
- bug fixes detected during the Beta pre-release
- enhancements as a consequence of testing GDP with the target boards
- the latest vc4 drm kernel drivers to support the RPi official 7" touchscreen.
Download GDP RC1 port for your favorite board or QEMU. Those with Yocto knowledge can build from scratch this first release candidate from GDP Master, where work is currently being done to support Renesas Porter, Silk and Qualcomm Dragonboard 410c boards which will take precedence in the final release. Other links of interest are:
- GDP 11 RC1 feature page is the place to read about what is new in this pre-release.
- GDP releases wiki page where you can find information about how to run the available GDP 11 RC1 ports to different boards. This is of interest to those application developers who are not familiar with Yocto.
- GDP Master wiki page, with instructions to build from scratch GDP with support to a wider range of target boards if you have Yocto knowledge.
- GDP bug tracking system for those of you who want to provide feedback about this release. The GDP Delivery Team love bug reports!
- GDP roadmap if you are interested in the coming GDP 11 release.
We very much appreciate any and all testing of the GDP 11 RC1 as it helps us create a better development platform for those interested in producing automotive software.
