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:

= R-Car Linux =
 
 
== Upstream ==
 
 
Renesas mainline R-Car Linux tree is maintained by [http://horms.org/about_me.shtml 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==
 
*Mailing list - via kernel.org [mailto:majordomo@vger.kernel.org?body=subscribe linux-sh Majordomo].
 
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/
 
 
== LTSI (Long Term Support Initiative) ==
 
 
Renesas SoCs and boards are supported as part of LTSI project - http://ltsi.linuxfoundation.org/ . Refer to [http://ltsi.linuxfoundation.org/releases/ltsi-tree/3.10.31-ltsi/stable-release 3.10] and [http://ltsi.linuxfoundation.org/releases/ltsi-tree/3.14.24-rc1-ltsi/release-candidate 3.14] baselines
 
 
== Renesas Stable R-Car BSP Tree ==
 
 
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 =
 
 
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
 
 
= 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 ?= " \
 
                <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
 
 
= 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 =
 
 
TBD ''This section will be added later''
