Introduction
This is the starting page for Embedded Linux on the Renesas RZ/G family of 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 can 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.

RZ/G Yocto Linux
The Linux BSP for RZ/G is built using the Yocto/Openembedded project.
Build instructions
Detailed build instructions are available here: RZ-G/Boards/Yocto.
Quick steps
To get started, pull the https://github.com/renesas-rz/meta-renesas tree.
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 \
"
Specify the associated machine in local.conf:
MACHINE ?= "<supported board name>" (skrzg1m skrzg1e)
Setup be build environment using the 'oe-init-build-env' script in Poky:
$ source poky/oe-init-build-env
Build the target file system image using bitbake:
$ bitbake core-image-minimal
