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)

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.:

    <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/'.

Images generated: * Image (generic Linux Kernel binary image file) * Image-.dtb (DTB for target machine) * core-image-minimal-.tar.bz2 (rootfs tar+bzip2) * core-image-minimal-.ext4 (rootfs ext4 format) * core-image-minimal-.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’ *

Usage of toolchain SDK: Install the SDK to the default: /opt/poky/x.x For 64-bit target SDK:

$ sh

For 64-bit application use environment script in /opt/poky/x.x

$ source /opt/poky/x.x/environment-setup-aarch64-poky-linux
