Initial check-in
Initial check-in of the contents of the meta-refhw directory from
the AGL_Refhw_sample_software_20200512.tar.gz archive provided by
Panasonic as the initial BSP for the AGL reference hardware. The
only change from the files as provided is that unneeded execute
file permissions have been removed.

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.
