meta-rcar-gen3
==============
This layer provides that evaluation board is mounted ARM SoCs of Renesas
Electronics, called the R-Car Generation 3. Currently, this supports
board and the SoCs of the following:
- Board: Salvator-X / SoC: R8A7795 (R-Car H3), R8A7796 (R-Car M3)
- Board: R-Car Starter Kit premier(H3ULCB) / SoC: R8A7795 (R-Car H3)
- Board: R-Car Starter Kit pro(M3ULCB) / SoC: R8A7796 (R-Car M3)
Patches
=======
Please submit any patches for this layer to: takamitsu.honda.pv@renesas.com
Please see the MAINTAINERS file for more details.
Dependencies
============
This layer depends on:
URI: git://git.yoctoproject.org/poky
layers: meta, meta-yocto, meta-yocto-bsp
branch: krogoth
URI: git://github.com/renesas-rcar/meta-renesas
layers: meta-rcar-gen3
branch: krogoth
URI: git://git.linaro.org/openembedded/meta-linaro.git
layers: meta-optee
branch: krogoth
URI: git://git.openembedded.org/meta-openembedded
layers: meta-oe
branch: krogoth
Build Instructions
==================
The following instructions require a Poky installation (or equivalent).
Initialize a build using the 'oe-init-build-env' script in Poky. e.g.:
$ source poky/oe-init-build-env
After that, initialized configure bblayers.conf by adding meta-rcar-gen3 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/meta-rcar-gen3 \
<path to layer>/meta-linaro/meta-optee \
<path to layer>/meta-openembedded/meta-oe \
"
To build a specific target BSP, configure the associated machine in local.conf:
MACHINE ??= "<supported board name>"
Select the SOC
For H3: r8a7795
SOC_FAMILY = "r8a7795"
For M3: r8a7796
SOC_FAMILY = "r8a7796"
Must change the package class to ipk files in local.conf:
PACKAGE_CLASSES ?= "package_ipk"
Configure for systemd init in local.conf:
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
Build the target file system image using bitbake:
$ bitbake core-image-minimal
After completing the images for the target machine will be available in the output
directory 'tmp/deploy/images/<supported board name>'.
Images generated:
* Image (generic Linux Kernel binary image file)
* Image-<machine name>.dtb (DTB for target machine)
* core-image-minimal-<machine name>.tar.bz2 (rootfs tar+bzip2)
* core-image-minimal-<machine name>.ext4 (rootfs ext4 format)
* core-image-minimal-<machine name>.cpio.gz (rootfs cpio+gz format)
Build Instructions for SDK
==========================
This may be changed in the near feature. These instructions are tentative.
Should define the staticdev in SDK image feature for installing the static libs
to SDK in local.conf.
SDKIMAGE_FEATURES_append = " staticdev-pkgs"
Use bitbake -c populate_sdk for generating the toolchain SDK:
For 64-bit target SDK (aarch64):
$ bitbake core-image-minimal -c populate_sdk
The SDK can be found in the output directory 'tmp/deploy/sdk'
* poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
Usage of toolchain SDK:
Install the SDK to the default: /opt/poky/x.x
For 64-bit target SDK:
$ sh poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
For 64-bit application use environment script in /opt/poky/x.x
$ source /opt/poky/x.x/environment-setup-aarch64-poky-linux
