This is the starting page for Embedded Linux on the Renesas RZ-G family of general embedded SoCs. The main goal is to make the information about RZ-G SoCs friendly, easy to access for embedded developers and enthusiasts. It does not aim to replace official Renesas support.

The links below could be used to get familiar with Renesas RZ-G SoC

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


Renesas RZ-G SoC variants
Generation 1
"M" - Mid range 1M - R8A7743
"E" - Entry class 1E - R8A7745

RZ-G Linux


Renesas mainline R-Car and RZ-G 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

RZ-G Community

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 the LTSI project - http://ltsi.linuxfoundation.org/ . Refer to 3.10 and 3.14 baselines

Renesas Stable RZ-G BSP Tree

Stable Renesas R-Car and RZ-G 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

RZ-G U-Boot

RZ-G 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 the renesas/bsp/rcar-gen2-1.8.0 branch and build U-Boot for the RZ/G1E and RZ/G1M Starter Kit 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

RZ-G Yocto

Renesas Yocto/Poky distribution is maintained by Nobuhiro Iwamatsu.

To get started with Yocto on the RZ-G platform - pull the https://github.com/renesas-rz/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 the meta-renesas and meta-rzg1 layers. 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-rzg1 \

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

       MACHINE ?= "<supported board name>" (skrzg1m skrzg1e)

Build the target file system image using bitbake:

       $ bitbake core-image-minimal
