Building

  • Download proprietary Multimedia & Graphics library and related Linux drivers. For R-Car, you can find them on Renesas' website.
  • Place the zip files in $HOME/Downloads (or $XDG_DOWNLOAD_DIR) so it looks like this:
$ ls -l ~/Downloads/R-Car_Gen3_Series_Evaluation_Software_Package_*
-rw-r--r-- 1 msisov msisov 4668616 May 12 12:18 /home/msisov/Downloads/R-Car_Gen3_Series_Evaluation_Software_Package_for_Linux-20170427.zip

  • Download the AGL sources. For R-Car Gen3, be sure to use the master branch or Grumpy Guppy 7.0.2 branch.
  • After all the sources are downloaded (repo init && repo sync), initialize the environment and configuration. For example, for RCar-M3:
source meta-agl/scripts/aglsetup.sh -m m3ulcb agl-demo agl-devel

You should see how it decompresses all the binary blobs and copies them.

  • Now start the build:
bitbake agl-demo-platform

  • After you have checked it can build the base demo fine, then add meta-browser and meta-openembedded/meta-gnome to the BBLAYERS variable of your bblayers.conf.

  • To handle media, set PACKAGECONFIG_pn-chromium-ozone-wayland to proprietary-codecs.

  • You can now build chromium:

  bitbake chromium-ozone-wayland

You can also append chromium-ozone-wayland to the image by setting IMAGE_INSTALL_append = " chromium-ozone-wayland" in your local.conf and rebuild agl-demo-platform so that chromium is installed by default.

Installation

Instructions below are based on the AGL doc for M3/H3 and on the elinux documentation for Gen3.

  • Find your microSD card with dmesg and format it with fdisk:
sudo fdisk /dev/YOURSDCARD
# Note: This deletes partition if there is one on your microSD card:
Command (m for help): d
Selected partition 1
Partition 1 has been deleted.
Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): 
Using default response p.
Partition number (1-4, default 1): 
First sector (2048-31291391, default 2048): 
Last sector, +sectors or +size{K,M,G,T,P} (2048-31291391, default 31291391): 
Created a new partition 1 of type 'Linux' and of size 14,9 GiB.
# Note: elinux suggests to do "t", "83" to force the partition type to 'Linux'.
Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
  • Create a new ext4 partition:
sudo mkfs.ext4 /dev/YOURSDCARD1
mke2fs 1.42.12 (29-Aug-2014)
/dev/sdb1 contains a ext4 file system
	last mounted on / on Mon Dec  5 13:53:59 2016
Proceed anyway? (y,n) y

Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
  • Keep the SD-Card unmount and write the image to that:
xzcat ./agl-demo-platform-m3ulcb.wic.xz | sudo dd of=$SDCARD bs=4M
  • Mount the SD-Card and copy Kernel Image and Device Tree Blob file into /mnt/boot/ 
sudo cp build/tmp/deploy/images/m3ulcb/Image-r8a7796-m3ulcb.dtb /mnt/boot/
  • Sync and umount:
sync
sudo umount /mnt/

Running AGL & Chromium

  • Perform the various connection of your R-Car M3 (see elinux and this video for some help)

  • For the first boot, the R-Car M3 will try and perform a network boot and you MAY need to change the default boot sequence. If the device boots normally, skip this section. Otherwise, connect the "CPLD debug" port to your computer. Connect to the shell with sudo screen /dev/ttyUSB0 115200, press the power button of the R-Car M3 and immediately any key to interrupt the default boot. In the U-boot shell, configure the boot sequence as follows (again, be careful that the /boot/ paths correspond to what is on your microSD card):

setenv bootargs console=ttySC0,115200 ignore_loglevel vmalloc=384M video=HDMI-A-1:1920x1080-32@60 root=/dev/mmcblk1p1 rw rootfstype=ext4 rootwait rootdelay=2 setenv bootcmd run load_ker\; run load_dtb\; booti 0x48080000 - 0x48000000 setenv load_ker ext4load mmc 0:1 0x48080000 /boot/Image

setenv load_dtb ext4load mmc 0:1 0x48000000 /boot/Image-r8a7796-m3ulcb.dtb
  • (Re)boot your board.
  • Once the board is up and running, open a terminal and change shell type from ivi-shell to desktop-shell in /etc/xdg/weston/weston.ini and reboot.
  • Once AGL & weston are started, open a terminal and launch chromium with the following command:
google-chrome
