Adding the meta-agl-refhw-gen3 layer to your AGL environment +============================================================== + +You can add this layer to your AGL HH environemnt as following: + +1. Put meta-refhw folder into the "$AGL_TOP/bsp" directory where AGL BSP layers + like meta-renesas-rcar-gen3/ are placed. + # See "Downloading AGL Software" in AGL developper site. + +2. Put refhw-h3 folder into the meta-agl/templates/machine where other machine + configuration files are placed. + +II. Build for Reference Hardware +================================ +You should follow the instructions in "Building for Supported Renesas Boards" +section in AGL developper site to build images for reference hardware. + +The modification needed is to set machine to "refhw-h3" when execute +aglsetup.sh (parameter of "-m" option). + + $ cd $AGL_TOP + $ source meta-agl/scripts/aglsetup.sh -m refhw-h3 -b build \ + agl-devel agl-demo agl-netboot agl-appfw-smack agl-localdev + +The "real" MACHINE in the internal building is set to "salvator-x" so that we +can divert the configurations defined for salvator-x. While, the DTB file used +by reference hardware is "r8a7795-refhw.dtb". so the settings in u-boot is +expected as 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-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-refhw.dtb + load_ker=ext4load mmc 0:1 0x48080000 /boot/Image + .. + +III.

There are suspicious HDMI0/1 interrupts detected and disabled forcely by + the kernel during boot. The reason is under investigation. |
