Back in August I blogged about the customer Yocto BSP v3.9.0 for YP 2.4 (Rocko). The customer BSP typically updates Yocto Project once a year. To help support the community Renesas is re-basing these releases on Sumo to create a community Yocto BSP.
Developer Summary
| Purpose | Repository location | Branch |
|---|---|---|
| Upstream Community Yocto BSP support | https://github.com/renesas-rcar/meta-renesas.git | sumo-dev |
Adapt Yocto BSP (meta-renesas) to Genivi Yocto Baseline (meta-ivi) | https://github.com/GENIVI/meta-ivi-renesas.git | genivi-14.x-sumo |
Migration Guide
If you wish to use the "click through" licensed gfx/mmp packages that requires no NDA then please download the packages for
Yocto v3.9.0 and Wayland 1.13 / Weston 2.0 from the section for YP 2.5 (Sumo) from here.
...
Details of the Yocto BSP changes can be found in the git commit messages. Here is a log between v3.9.0 (Rocko) and v3.9.0 (Sumo) using the github compare function.
The customer v3.9.0 (Rocko) BSP supports two render methods in Weston, v4l2-renderer and gl-renderer. The latter being the default and for which the GPU alone is used for h/w acceleration. The community v.3.9.0 (Sumo) BSP uses the upstream (Poky) Weston 3.0 implementation and therefore only supports the gl-renderer . As gl-renderer was the default anyway this will only impact some people but I wanted to call out the change in the migration guidewhich uses the GPU for h/w acceleration.
The dtb filenames have not changed since the last blog but here is the table again for reference. Please refer to the table below for the correct dtb to use for your board and SoC:
| Board | SoC | DTB filename |
|---|---|---|
| Ebisu | E3 | Image-r8a77990-ebisu.dtb |
| M3 Starter Kit | M3 | Image-r8a7796-m3ulcb.dtb |
| Salvator-X | M3 | Image-r8a7796-salvator-x.dtb |
| Salvator-XS | M3 | Image-r8a7796-salvator-xs.dtb |
| Salvator-X | M3N 1.1 | Image-r8a77965-salvator-x.dtb |
| Salvator-XS | M3N 1.1 | Image-r8a77965-salvator-xs.dtb |
| H3 Starter Kit | H3 1.0, 1.1 | Image-r8a7795-es1-h3ulcb.dtb |
| H3 Starter Kit | H3 2.0 | Image-r8a7795-h3ulcb.dtb |

Documentation
Historically I have maintained continue to maintain pages discussing the building of Genivi s/w for R-Car in the meta-ivi Yocto BSP wiki area. I have created a new page covering R-Car Gen 3 builds for Genivi-14 (Pulsar) for YP 2.5 (Sumo).
...
I have successfully sanity tested building the 14.50.x Genivi Yocto Baseline using the Community YBSP v3.9.0 for Sumo on the M3 Starter Kit. Testing of the other boards will follow, but I do not expect any issues and see no reason for you to wait before trying them.
See the Documentation section above on how to build it.
...
The GDP Master and 14.1.x-sumo branches have been updated to use the Community Yocto BSP v3.9.0 for Sumo. I have also updated the corresponding build instructions of the GDP Master wiki page. Finally, I have successfully sanity tested it on the M3 Starter Kit. As with the Baseline testing of the other boards will follow.
