meta-rcar-gen3

This layer provides the support for the evaluation board mounted ARM SoCs of Renesas Electronics, called the R-Car Generation 3.

Currently, this supports boards and the SoCs of the following:

    - Board: Salvator-X / SoC: R8A77950/R8A77951 (R-Car H3), R8A77960/R8A77961 (R-Car M3), R8A77965 (R-Car M3N)
    - Board: R-Car Starter Kit premier(H3ULCB) / SoC: R8A77950/R8A77951 (R-Car H3)
    - Board: R-Car Starter Kit pro(M3ULCB) / SoC: R8A77960/R8A77961 (R-Car M3)
    - Board: R-Car Starter Kit pro(M3NULCB) / SoC: R8A77965 (R-Car M3N)
    - Board: Ebisu / SoC: R8A77990 (R-Car E3)
    - Board: Draak / SoC: R8A77995 (R-Car D3)

Layer Dependencies

This layer depends on:

• poky

    URI: git://git.yoctoproject.org/poky
    layers: meta, meta-poky, meta-yocto-bsp
    branch: dunfell

• meta-openembedded

    URI: git://git.openembedded.org/meta-openembedded
    layers: meta-oe, meta-python
    branch: dunfell

Build Instructions

The following instructions require a Poky installation (or equivalent).

• This also needs git user name and email defined:

   $ git config --global user.email "[email protected]"
   $ git config --global user.name "Your Name"

• 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-poky \
        <path to layer>/poky/meta-yocto-bsp \
        <path to layer>/meta-renesas/meta-rcar-gen3 \
        <path to layer>/meta-openembedded/meta-python \
        <path to layer>/meta-openembedded/meta-oe \
    "

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

    MACHINE ??= "<supported board name>"

Board	MACHINE
Salvator-X/XS	MACHINE = "salvator-x"
Ebisu	MACHINE = "ebisu"
Starter Kit Pro (M3ULCB)	MACHINE = "m3ulcb"
Starter Kit Pro (M3NULCB)	MACHINE = "m3nulcb"
Starter Kit Premier (H3ULCB)	MACHINE = "h3ulcb"
Draak	MACHINE = "draak"

• Select the SOC

  • For H3: r8a7795

      SOC_FAMILY = "r8a7795"
  • For M3: r8a7796

      SOC_FAMILY = "r8a7796"
  • For M3N: r8a77965

      SOC_FAMILY = "r8a77965"
  • For E3: r8a77990

      # Already added in machine config: ebisu.conf
      SOC_FAMILY = "r8a77990"
  • For D3: r8a77995

      # Already added in machine config: draak.conf
      SOC_FAMILY = "r8a77995"

• Configure for systemd init in local.conf:

    DISTRO_FEATURES_append = " systemd"
    VIRTUAL-RUNTIME_init_manager = "systemd"

• Configure for ivi-shell and ivi-extension

    DISTRO_FEATURES_append = " ivi-shell"

• Configure for USB 3.0

    MACHINE_FEATURES_append = " usb3"

• Enable tuning support for Capacity Aware migration Strategy (CAS)

    MACHINE_FEATURES_append = " cas"

• For a list of sample local.conf file, please refer to: docs/sample/conf/

• 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)

• <SoC>-<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)

Build Instructions for SDK

NOTE:

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"

For 64-bit target SDK (aarch64)

Use bitbake -c populate_sdk for generating the toolchain SDK

    $ 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-<machine name>-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-<machine name>-toolchain-x.x.sh

• For 64-bit application, using environment script in /opt/poky/x.x

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