= Introduction =

This is starting page for Embedded Linux on Renesas R-Car family of automotive embedded SoCs. Main goal is to make information on R-Car SoCs friendly, easy to access for embedded developers, enthusiasts. It does not aim to replace official Renesas support.

Links below could be used to get familiar with Renesas Automotive SoCs and R-Car Concortia:
 * Renesas Automotive Products / Solutions
 * Renesas Car Information Terminal Applications
 * R-Car Consortium

Detailed information regarding R-Car SoCs (including roadmap, technical and marketing documents, BSPs and middleware) can be obtained directly from Renesas representative.

= R-Car SoCs =

The R-Car devices pages lists the peripheral devices available in the R-Car SoCs along with usage information and test procedures.

= R-Car Boards =

= R-Car Linux =

Upstream
Renesas mainline R-Car Linux tree is maintained by Simon Horman

Start here to get latest/closest upstream kernel: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git

e.g. pull development branch: git clone -b devel git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git

TBD - add page regarding R-Car upstream development process (including branches/tags meaning)

R-Car Community
Archives available here: http://dir.gmane.org/gmane.linux.kernel.renesas-soc, http://www.spinics.net/lists/linux-renesas-soc/
 * Mailing list - via kernel.org [mailto:majordomo@vger.kernel.org?body=subscribe linux-renesas-soc Majordomo].

LTSI (Long Term Support Initiative)
Renesas SoCs and boards are supported as part of LTSI project - http://ltsi.linuxfoundation.org/. Refer to 4.1.17-LTSI and 3.14.28-LTSI.

Renesas R-Car Gen 2 BSP Tree
Renesas R-Car Gen 2 BSP Tree located at: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-backport.git. Check out the latest R-Car Gen 2 BSP release tag.

for example: rcar-gen2/v1.9.7

Renesas R-Car Gen 3 BSP Tree
Renesas R-Car Gen 2 BSP Tree located at: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-bsp.git. Check out the latest R-Car Gen 3 BSP release tag.

for example: rcar-3.2.1

= R-Car U-Boot =

R-Car U-Boot mainline development is done using git://git.denx.de/u-boot-sh.git tree. It is maintained by Nobuhiro Iwamatsu.

e.g. pull renesas/bsp/rcar-gen2-1.8.0 branch and build U-Boot for Lager/Koelsch/Alt boards git clone -b renesas/bsp/rcar-gen2-1.8.0 git://git.denx.de/u-boot-sh.git

build example make O=/tmp/build clean make O=/tmp/build mrproper make O=/tmp/build gose_config make O=/tmp/build all

= R-Car Yocto =

Renesas Yocto/Poky distribution is maintained by Nobuhiro Iwamatsu.

To get started with Yocto on R-Car Gen2 platform - pull git://git.yoctoproject.org/meta-renesas tree

If you pulled complete Yocto/poky trees, you should be able to kick-off a build using the 'oe-init-build-env' script in Poky. Update bblayers.conf by adding the meta-renesas and meta-rcar-gen2 layer. e.g.:

BBLAYERS ?= " \               /poky/meta \                /poky/meta-yocto \                /poky/meta-yocto-bsp \                /meta-renesas \                /meta-renesas/meta-rcar-gen2 \        "

To build a specific target BSP configure the associated machine in local.conf:

MACHINE ?= " " (lager, koelsch, gose, alt)

Build the target file system image using bitbake:

$ bitbake core-image-minimal

= R-Car Automotive Grade Linux =

Automotive Grade Linux (AGL) is a Linux Foundation Workgroup dedicated to creating open source software solutions for automotive applications. AGL is based on Yocto project for its construction and R-Car Porter board can be used to start an AGL distribution. Please check this page.

= R-Car Genivi = GENIVI® is a nonprofit industry alliance committed to driving the broad adoption of specified, open source, In-Vehicle Infotainment (IVI) software. Source: http://www.genivi.org/

As a service to the community Renesas maintains a git repository containing a R-Car Yocto BSP with the changes required for the standard Yocto BSP to work with the Genivi Yocto Baseline and Genivi Development Platform (GDP) already integrated. It is supported on a best effort basis.

You can find more information about building the Genivi Yocto Baseline for various Genivi versions in the Alliance pages for meta-ivi here. Information on building GDP for R-Car M2 Porter can be found here and E2 Silk here.

= R-Car Tizen =

TBD ''Renesas R-Car Tizen is already available via tizen.org trees. Add detailed instructions how to get started with Tizen for R-Car''

= R-Car Android =
