BSP Differences Between renesas.com Download and Github Version

Below are the differences between BSP you download from renesas.com and what is available on public repositories.

Public Repository Clones

• meta-gplv2/
• meta-linaro/
• meta-openembedded/
• meta-qt5/
• meta-rzg2/
• meta-virtualization/
• poky/

These directories are direct clones (no modifications) from public repositories. The repository URLs and commit IDs that were used are documented in the README.md file in the meta-rzg2 directory in the BSP.

Example Layers

• meta-hmi-custom/
• meta-userboard/

These directories do not have any functionally. They are simple example templates you can use to make your own customer layers. They are only included in the renesas.com package.

The RZ/G2 BSP

• meta-rzg2/

Basically, all the customizations and patches are located in the directory 'meta-rzg2'.
This directory is a clone of the public repository is located here: https://github.com/renesas-rz/meta-rzg2.
There are git tags for BSP version that was release.
The only difference is that in the renesas.com version, the following lines were added to the local.conf files under docs/sample/conf

DL_DIR = "${TOPDIR}/oss_packages"

BB_NO_NETWORK = "0"

Additionally, other configuration files such as bblayers_gecko.conf and local_gecko.con are added to the renesas.com download that are not in the github version.

Non-public Patches

• extra/

This directory is only in the package downloaded from renesas.com
It contains patches that are not included in the public the meta-rzg2 repository on github. For example, the patches to enable HDMI on the boards were not posted to github because of potential license issues.

Video and Multi-media Drivers

• proprietary/

This directory is only in the package downloaded from renesas.com
This directory contains .zip files which are essentially the propriety closed source video and multimedia drivers. They used to be downloaded separately, but are now included when downloaded the BSP from renesas.com. When following the instructions in the "Renesas Note" that comes with the BSP, users will run the script copy_proprietary_softwares.sh which will unpack these zip files into various directories under meta-rzg2.

Fix RZ/G2H eMMC boot for VLP64 v1.0.5-RT and v1.0.6

For the BSP releases of v1.0.5-RT and v1.0.6, a patch in the arm-trusted-firmware code was missing for RZ/G2H that prevented it from booting from eMMC. While RZ/G2H eMMC boot support exists in v1.0.4, for the v1.0.5 code release, the base software repository changed from the R-Car repository to the official ARM repository and new "rzg" subdirectory were created. With all these changes, this eMMC boot patch was unfortunately missed.

Please apply the patch below to your arm-trusted-firmware code base if you are using a RZ/G2H and require booting from eMMC.

Note: The same patch file can be used for all variations of v1.0.5 and v1.0.6 releases

$ wget https://raw.githubusercontent.com/seebe/rzg_stuff/master/build_scripts/vlp64_patches/BSP-1.0.5-RT/arm-trusted-firmware/fix-G2H-eMMC-boot_patch/0001-hihope-rzg2h-pfc-update.patch

Fix broken links to video files for VLP64 v1.0.5-RT and v1.0.6

The Renesas.com website was recently changed, and now the links for the sample video movies for the Yocto recipes-demos have become broken.

A patch to the meta-rzg2 Yocto layer is required to fix the URL.

Note: The same patch file can be used for all variations of v1.0.5 and v1.0.6 releases.

SPI Flash Driver for BSP 1.0.6

SPI flash write from Linux is not officially supported in V1.0.6 BSP. If you want SPI write enabled for BSP 1.0.6. Please follow the below steps:

1. Add kernel patches to BSP

1.a) Please get required patch files from https://github.com/seebe/rzg_stuff/tree/master/build_scripts/vlp64_patches/BSP-1.0.6-SPI-write/kernel

$ rzg2_bsp_eva_v106/recipes-kernel/linux/linux-renesas/patches
$ mkdir v1.0.6_spi_patch
$ cd v1.0.6_spi_patch #copy patch files here

1.b) Update patches.scc file:

Yocto uses .scc file to apply patches located in ~/rzg2_bsp_eva_v106/meta-rzg2/recipes-kernel/linux/linux-renesas/patches.scc. Get updated .scc file from https://github.com/seebe/rzg_stuff/tree/master/build_scripts/vlp64_patches/BSP-1.0.6-SPI-write/

$ cd ~/rzg2_bsp_eva_v106/meta-rzg2/recipes-kernel/linux/linux-renesas/
$ wget https://raw.githubusercontent.com/seebe/rzg_stuff/master/build_scripts/vlp64_patches/BSP-1.0.6-SPI-write/patches.scc

2. Configuring kernel using menuconfig

Configure the kernel to enable Renesas SPI driver and SPI memory. The following commands initialize the BitBake environment, run the do_kernel_configme task, and launch menuconfig. These commands assume the Source Directory's top-level folder is ~/rzg2_bsp_eva_v106:

$ cd rzg2_bsp_eva_v106
$ source poky/oe-init-build-env
$ bitbake linux-renesas -c kernel_configme -f
$ bitbake linux-renesas -c menuconfig

Once menuconfig comes up, configure below kernel configuration parameters.

2.a)Enable Renesa RPC-IF driver:

.config - Linux/arm64 4.19.140 Kernel Configuration
 > Device Drivers > Memory Controller drivers

2.b)Enable SPI memory (M25P80 ):

.config - Linux/arm64 4.19.140 Kernel Configuration
 > Device Drivers > Memory Technology Device (MTD) support > Self-contained MTD device drivers 

After making your changes, simply exit the tool and save your changes to create an updated version of the .config configuration file

3. Build the image using updated BSP
