This README file contains information on the contents of the meta-agl-refhw-gen3 layer which provides support for the Renesas R-Car H3 based AGL reference hardware. Dependencies ============ This layer depends on: URI: git://git.openembedded.org/openembedded-core layers: meta branch: dunfell URI: git://git.openembedded.org/meta-openembedded layers: meta-oe, meta-python branch: dunfell URI: https://github.com/renesas-rcar/meta-renesas branch: dunfell-dev-4.14 Build Instructions ================== I. Building with the layer in the AGL environment II. Build agl-demo-platform by using meta-agl-refhw-gen3 III. Updating firmware IV. Notes I. Adding the meta-agl-refhw-gen3 layer to your AGL environment =============================================================== This layer has been integrated into the AGL build environment for the UCB 11.0 (Kooky Koi) release, so manual integration is no longer required. See section (II) below for how to build an image, and the "How to build the Firmware" section in the document meta-agl-refhw-gen3/docs/ReferenceHW_Rcar_gen3.md for how to configure a standalone build without AGL. II. Build for Reference Hardware ================================ You should follow the instructions in the "Building for Supported Renesas Boards" section on the AGL developer site to build images for the reference hardware. Use the "h3ulcb" machine when configuring, e.g.: $ cd $AGL_TOP $ source meta-agl/scripts/aglsetup.sh -m h3uclb -b build \ agl-devel agl-demo agl-localdev This works as the AGL reference hardware support has been integrated with the "h3ulcb" (and "h3ulcb-nogfx") machine templates in the AGL UCB tree. In the resulting build, the image can be used on the reference hardware by using the DTB file "r8a7795-agl-refhw.dtb". In the reference hardware u-boot settings, this can be done with the following (in case of booting from the Micro SD card in SD#0): => setenv bootargs 'console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4' => setenv bootcmd 'run load_ker; run load_dtb; booti 0x48080000 - 0x48000000' => setenv load_dtb 'ext4load mmc 0:1 0x48000000 /boot/r8a7795-agl-refhw.dtb' => setenv load_ker 'ext4load mmc 0:1 0x48080000 /boot/Image' => saveenv => printenv ... bootargs=console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4 bootcmd=run load_ker; run load_dtb; booti 0x48080000 - 0x48000000 load_dtb=ext4load mmc 0:1 0x48000000 /boot/r8a7795-agl-refhw.dtb load_ker=ext4load mmc 0:1 0x48080000 /boot/Image .. III. Updating firmware ====================== Please refer to meta-agl-refhw-gen3/docs/ReferenceHW_Rcar_gen3.md for details. IV. Notes ========= 1. SD#1 is not supported. 2. There are suspicious HDMI0/1 interrupts detected and disabled forcibly by the kernel during boot. The reason is under investigation.
