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

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)
Archives available here: http://marc.info/?l=linux-sh , http://dir.gmane.org/gmane.linux.ports.sh.devel , http://www.spinics.net/lists/linux-sh/
Renesas SoCs and boards are supported as part of LTSI project - http://ltsi.linuxfoundation.org/ . Refer to 3.10 and 3.14 baselines
Stable Renesas R-Car BSP Tree located here: git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-backport.git. Pull latest stable branch.
for example: bsp/v3.10.31-ltsi/rcar-gen2-1.8.0
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
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 ?= " \
<path to layer>/poky/meta \
<path to layer>/poky/meta-yocto \
<path to layer>/poky/meta-yocto-bsp \
<path to layer>/meta-renesas \
<path to layer>/meta-renesas/meta-rcar-gen2 \
"
To build a specific target BSP configure the associated machine in local.conf:
MACHINE ?= "<supported board name>" (lager, koelsch, gose, alt)
Build the target file system image using bitbake:
$ bitbake core-image-minimal
TBD Renesas R-Car Tizen is already available via tizen.org trees. Add detailed instructions how to get started with Tizen for R-Car
TBD This section will be added later
