=== Branches ===

* '''master'''
 +
** Current development version
 +
** Based on latest upstream point or rc release
 +
** Includes patches queued up for the forthcoming kernel release (or later)

** Includes 'topic/renesas-defconfig'

* '''next'''
 +
** Patches queued up for the forthcoming kernel release
 +
** This is included in linux-next and complies with its rules
 +
** It is a feeder for submissions (pull requests) to the ARM-SoC maintainers
 +
** It is generally based on the latest rc1 release but may be based on a later rc release in order to provide a working kernel for ARM (32-bit) and ARM64 based Renesas SoCs.
 +
* '''*-for-vX.Y'''
 +
** Individual patch-queues for the ARM-SoC maintainers as per their requirements for patches to be broken out into branches
 +
** Patches are targeted at kernel version X.Y
 +
** Merged into next
 +
* '''topic/renesas-defconfig'''
 +
** Sample defconfig file for Renesas R-Car Gen3 and RZ/G2 boards
 +
** Not intended for upstream merge
 +
* '''topic/*'''
 +
** Branches for specific new features
 +
** Pushed when the features are under review of otherwise not queued up for submission to the ARM-SoC maintainers

** Temporary branches typically for testing purposes

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:

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

R-Car Linux

Upstream

Renesas mainline R-Car Linux tree is maintained by Geert Uytterhoeven

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

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

Branches

  • master
    • Current development version
    • Based on latest upstream point or rc release
    • Includes patches queued up for the forthcoming kernel release (or later)
    • Includes 'topic/renesas-defconfig'
  • next
    • Patches queued up for the forthcoming kernel release
    • This is included in linux-next and complies with its rules
    • It is a feeder for submissions (pull requests) to the ARM-SoC maintainers
    • It is generally based on the latest rc1 release but may be based on a later rc release in order to provide a working kernel for ARM (32-bit) and ARM64 based Renesas SoCs.
  • *-for-vX.Y
    • Individual patch-queues for the ARM-SoC maintainers as per their requirements for patches to be broken out into branches
    • Patches are targeted at kernel version X.Y
    • Merged into next
  • topic/renesas-defconfig
    • Sample defconfig file for Renesas R-Car Gen3 and RZ/G2 boards
    • Not intended for upstream merge
  • topic/*
    • Branches for specific new features
    • Pushed when the features are under review of otherwise not queued up for submission to the ARM-SoC maintainers
  • other
    • Temporary branches typically for testing purposes

Hardware Support Status (Incomplete)

LTSI (Long Term Support Initiative)

Renesas SoCs and boards are supported as part of LTSI project - https://ltsi.linuxfoundation.org/ .For all LTSI kernel releases, refer to https://ltsi.linuxfoundation.org/software/releases.

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 3 BSP Tree located at: https://github.com/renesas-rcar/linux-bsp.git. Check out the latest R-Car Gen 3 BSP release tag.

for example: rcar-3.9.2

NOTE: The git repo at git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas-bsp.git become outdated from Oct 2019.

R-Car U-Boot

For Gen3 see U-Boot-Gen3.

R-Car U-Boot mainline development is done using git@gitlab.denx.de:u-boot/custodians/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@gitlab.denx.de:u-boot/custodians/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

  • For Gen3, see Yocto-Gen3
  • Community BSP following official Yocto Project versions
    Refer to README.md for release policy and build instructions.
    To integrate evaluation version of proprietary graphics and multimedia drivers from Renesas, refer to README.evaproprietary.md.
    Repository location: https://github.com/renesas-rcar/meta-renesas.git
    Latest R-Car Gen3 Community BSP
    Yocto Project (YP) releases Branch name Tag name For build instructions, refer to
    YP 2.5 (codename: sumo) sumo-dev sumo-Yocto-v3.15.0 README.md and README.evaproprietary.md
    YP 2.6 (codename: thud) thud-dev thud-Yocto-v3.21.0 README.md and README.evaproprietary.md
    YP 2.7 (codename: warrior) warrior-dev warrior-Yocto-v3.19.0 README.md and README.evaproprietary.md
    YP 3.0 (codename: zeus) zeus-dev zeus-Yocto-v3.21.0 README.md and README.evaproprietary.md
  • Renesas Yocto/Poky distribution
    Renesas Yocto/Poky distribution is maintained by Takamitsu Honda.
    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 Automotive Grade Linux

Automotive Grade Linux(TM) (AGL: https://www.automotivelinux.org/ ) is a Linux Foundation Workgroup dedicated to creating open source software solutions for automotive applications. AGL is based on Yocto project for its construction.

To start an AGL distribution on R-Car Porter board, please check this page.
To start an AGL distribution on R-Car Starter Kit(s), please check AGL documentation here.

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: https://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 Master for the Renesas R-Car SoCs can be found here.
