21 verified as compatible, it is recommended that it be used.

33 I. Adding the meta-agl-refhw-gen3 layer to your AGL environment
34 ===============================================================
36 This layer has been integrated into the AGL build environment for the UCB 11.0
37 (Kooky Koi) release, so manual integration is no longer required. See section
38 (II) below for how to build an image, and the "How to build the Firmware" section
39 in the document meta-agl-refhw-gen3/docs/ReferenceHW_Rcar_gen3.md for how to
40 configure a standalone build without AGL.
43 II. Build for Reference Hardware
44 ================================
46 You should follow the instructions in the "Building for Supported Renesas Boards"
47 section on the AGL developer site to build images for the reference hardware.
49 Use the "h3ulcb" machine and "agl-refhw-h3" feature when configuring, e.g.:
52 $ source meta-agl/scripts/aglsetup.sh -m h3ulcb -b build \
53 agl-refhw-h3 agl-demo agl-devel
55 This works as the AGL reference hardware support activated by the "agl-refhw-h3"
56 feature integrates on top of the "h3ulcb" (or "h3ulcb-nogfx") machine support in
57 the AGL UCB tree. Note that it has not been tested with the "h3ulcb-kf" machine.
58 In the resulting build, the image can be used on the reference hardware by using
59 the DTB file "r8a7795-agl-refhw.dtb". In the reference hardware u-boot settings,
60 this can be done with the following (in case of booting from the Micro SD card
63 => setenv bootargs 'console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4'
64 => setenv bootcmd 'run load_ker; run load_dtb; booti 0x48080000 - 0x48000000'
65 => setenv load_dtb 'ext4load mmc 0:1 0x48000000 /boot/r8a7795-agl-refhw.dtb'
66 => setenv load_ker 'ext4load mmc 0:1 0x48080000 /boot/Image'
71 bootargs=console=ttySC0,115200 root=/dev/mmcblk1p1 rootwait ro rootfstype=ext4
72 bootcmd=run load_ker; run load_dtb; booti 0x48080000 - 0x48000000
73 load_dtb=ext4load mmc 0:1 0x48000000 /boot/r8a7795-agl-refhw.dtb
