# 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:
```bash
- Board: Salvator-X / SoC: R8A7795 (R-Car H3), R8A7796 (R-Car M3), R8A77965 (R-Car M3N)
- Board: R-Car Starter Kit premier(H3ULCB) / SoC: R8A7795 (R-Car H3)
- Board: R-Car Starter Kit pro(M3ULCB) / SoC: R8A7796 (R-Car M3)
- Board: R-Car Starter Kit pro(M3NULCB) / SoC: R8A77965 (R-Car M3N)
- Board: Ebisu / SoC: R8A77990 (R-Car E3)
```
## Branch Policy
* This is Community Yocto BSP to follow Yocto/Poky releases.
* It is not supported to the level of the Customer Yocto BSP.
## Tag Policy
* Releases are created from the respective working branch.
* After a Customer Yocto BSP version releases, the Community Yocto BSP will be
rebased and released accordingly.
* dunfell-X:
* The versions used on dunfell (Yocto Project 3.1) will start on
dunfell-Yocto-v3.21.0 to keep the major version numbers in sync.
## Contribution
* Please submit any patches for this layer to: takamitsu.honda.pv@renesas.com
* Please see the MAINTAINERS file for more details.
## Layer Dependencies
This layer depends on:
* poky
```bash
URI: git://git.yoctoproject.org/poky
layers: meta, meta-poky, meta-yocto-bsp
branch: dunfell
```
* meta-openembedded
```bash
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:
```bash
$ git config --global user.email "you@example.com"
$ git config --global user.name "Your Name"
```
* Initialize a build using the 'oe-init-build-env' script in Poky. e.g.:
```bash
$ source poky/oe-init-build-env
```
* After that, initialized configure bblayers.conf by adding meta-rcar-gen3 layer.
e.g.:
```bash
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:
```bash
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"
* Select the SOC
* For H3: r8a7795
```bash
SOC_FAMILY = "r8a7795"
```
* For M3: r8a7796
```bash
SOC_FAMILY = "r8a7796"
```
* For M3N: r8a77965
```bash
SOC_FAMILY = "r8a77965"
```
* For E3: r8a77990
```bash
SOC_FAMILY = "r8a77990"
```
* Configure for systemd init in local.conf:
```bash
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
```
* Configure for ivi-shell and ivi-extension
```bash
DISTRO_FEATURES_append = " ivi-shell"
```
* Configure for USB 3.0
```bash
MACHINE_FEATURES_append = " usb3"
```
* Enable tuning support for Capacity Aware migration Strategy (CAS)
```bash
MACHINE_FEATURES_append = " cas"
```
* For a list of sample local.conf file, please refer to: [docs/sample/conf/](https://git.automotivelinux.org/AGL/meta-renesas-rcar-gen3/tree/meta-rcar-gen3/docs/sample/conf)
* Build the target file system image using bitbake:
```bash
$ 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)
* \<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.
```bash
SDKIMAGE_FEATURES_append = " staticdev-pkgs"
```
### For 64-bit target SDK (aarch64)
Use `bitbake -c populate_sdk` for generating the toolchain SDK
```bash
$ 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
```bash
$ sh poky-glibc-x86_64-core-image-minimal-aarch64-toolchain-x.x.sh
```
* For 64-bit application, using environment script in `/opt/poky/x.x`
```bash
$ source /opt/poky/x.x/environment-setup-aarch64-poky-linux
```
