</pre>
 
'''Image''' is a Kernel image, '''*.dtb''' is a blob file,  '''core-image-weston-h3ulcb.tar.bz2''' is the rootfs, '''modules-h3ulcb.tgz''' are kernel modules.
 
</li>
 
<li>
 
You can now proceed with running Yocto images
 
</li>
 
</ol>
 
 
 
== Running Yocto images ==
 
Linux kernel can be booted from microSD card or from TFTP. Root FS can be mounted from micro SD card or via NFS.
 
 
 
=== Loading kernel via TFTP and rootfs via NFS ===
 
Follow these steps to setup working TFTP and NFS server:
 
<ol>
 
<li>
 
Setup a TFTP server.
 
==== Ubuntu ====
 
Install '''tftpd-hpa''' package along with tftp tools:
 
<pre>
 
sudo apt-get install tftp tftpd-hpa
 
</pre>
 
 
 
==== Fedora ====
 
<ol>
 
<li>
 
Install necessary packages:
 
<pre>
 
sudo yum install tftp-server tftp
 
</pre>
 
tftp-server is a part of xinetd. See [http://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/ch13s05s03.html Fedora manual] for more information.
 
</li>
 
<li>
 
Enable TFTP server:
 
<pre>
 
sudo vi /etc/xinetd.d/tftp
 
</pre>
 
Set <pre>disable = no</pre> Save file and exit.
 
</li>
 
<li>
 
Start xinetd:
 
<pre>
 
sudo systemctl start xinetd.service
 
sudo systemctl enable xinetd.service
 
</pre>
 
</li>
 
</ol>
 
 
 
</li>
 
 
 
<li>
 
Copy '''Image''' and '''Image-r8a7795-h3ulcb.dtb''' from $WORK/build/tmp/deploy/images/h3ulcb/ to TFTP server root.
 
==== Ubuntu ====
 
<pre>
 
cp $WORK/build/tmp/deploy/images/h3ulcb/Image /srv/tftp/
 
cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb /srv/tftp/
 
</pre>
 
 
 
==== Fedora ====
 
<pre>
 
cp $WORK/build/tmp/deploy/images/h3ulcb/Image /var/lib/tftpboot/
 
cp $WORK/build/tmp/deploy/images/h3ulcb/Image-r8a7795-h3ulcb.dtb /var/lib/tftpboot/
 
</pre>
 
</li>
 
 
 
<li>
 
Verify that TFTP server is working.
 
<pre>
 
tftp localhost -c get Image && ls Image
 
</pre>
 
</li>
 
 
 
<li>
 
Setup NFS server.
 
==== Debian/Ubuntu ====
 
<ol>
 
<li>
 
Install necessary packages:
 
<pre>
 
sudo apt-get install nfs-kernel-server nfs-common
 
</pre>
 
</li>
 
<li>
 
Start NFS server:
 
<pre>
 
sudo /etc/init.d/nfs-kernel-server start
 
</pre>
 
</li>
 
</ol>
 
 
 
==== Fedora ====
 
<ol>
 
<li>
 
Install necessary packages:
 
<pre>
 
sudo yum install nfs-utils
 
</pre>
 
</li>
 
<li>
 
Enable and start nfs server:
 
<pre>
 
sudo systemctl enable rpcbind.service
 
sudo systemctl enable nfs-server.service
 
sudo systemctl enable nfs-lock.service
 
sudo systemctl enable nfs-idmap.service
 
sudo systemctl start rpcbind.service
 
sudo systemctl start nfs-server.service
 
sudo systemctl start nfs-lock.service
 
sudo systemctl start nfs-idmap.service
 
</pre>
 
</li>
 
</ol>
 
</li>
 
 
 
<li>
 
Export root FS to NFS. (Change IMAGE and MACHINE to fit your build).
 
<ol>
 
<li>
 
Unpack rootfs to a dedicated directory:
 
<pre>
 
IMAGE=weston
 
MACHINE=salvator-x|h3ulcb|m3ulcb
 
NFS_ROOT=/nfs/${MACHINE}
 
sudo mkdir -p "${NFS_ROOT}"
 
sudo rm -rf "${NFS_ROOT}"/*
 
sudo tar -xjf "${WORK}/build/tmp/deploy/images/${MACHINE}/core-image-${IMAGE}-${MACHINE}-*.tar.bz2" -C "${NFS_ROOT}"
 
sync
 
</pre>
 
</li>
 
<li>
 
Edit '''/etc/exports''':
 
<pre>
 
sudo vi /etc/exports
 
</pre>
 
add
 
<pre>
 
/nfs/h3ulcb *(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
 
/nfs/salvator-x *(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
 
</pre>
 
Save the file and exit.
 
</li>
 
<li>
 
Force NFS server to re-read /etc/exports
 
<pre>sudo exportfs -a</pre>
 
</li>
 
</ol>
 
</li>
 
<li>
 
Verify that NFS is working.
 
<pre>
 
[builduser@buildmachine ~]$ showmount -e localhost
 
Export list for localhost:
 
/nfs/h3ulcb *
 
/nfs/salvator-x *
 
</pre>
 
</li>
 
 
 
<li><span id="Boot into U-Boot command prompt">Boot into U-Boot command prompt</span>
 
 
 
<ol>
 
<li>
 
Connect to serial console over microUSB using minicom or picocom.
 
</li>
 
<li>
 
Switch the board on or reset it. Press any key to stop U-Boot automatic countdown.
 
</li>
 
</ol>
 
Refer to [[R-Car/Boards/H3SK#Power_on_the_board_and_go_to_U-Boot_prompt|H3SK board page]], [[R-Car/Boards/M3SK#Power_on_the_board_and_go_to_U-Boot_prompt|M3SK board page]], [[R-Car/Boards/Salvator-X#Power_on_the_board_and_go_to_U-Boot_prompt|Salvator-X board page]] for more information.
 
</li>
 
 
 
<li>
 
Configure Ethernet, TFTP, and kernel command line in U-Boot:
 
<!--setenv ethaddr xx:xx:xx:xx:xx:xx
 
Replace xx:xx:xx:xx:xx:xx with the MAC address of your board. It should be on the sticker on top of the Ethernet port.<br/>
 
-->
 
<pre>
 
setenv ipaddr <board-ip>
 
setenv serverip <your-computer-ip>
 
setenv bootcmd 'tftp 0x48080000 Image; tftp 0x48000000 Image-r8a7795-h3ulcb.dtb; booti 0x48080000 - 0x48000000'
 
setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=<your-computer-ip>:<nfs-path>,nfsvers=3 ip=<board-ip>:<your-computer-ip>::255.255.255.0:h3ulcb'
 
saveenv
 
</pre>
 
Replace <board-ip> with the proper IP address for the board.  Replace <your-computer-ip> with the IP address of your computer, where tftp and nfs servers are installed. Replace <nfs-path> with the exported path of the root FS. <br/> For example:
 
<pre>
 
setenv ipaddr 192.168.1.3
 
setenv serverip 192.168.1.2
 
setenv bootcmd 'tftp 0x48080000 Image; tftp 0x48000000 Image-r8a7795-h3ulcb.dtb; booti 0x48080000 - 0x48000000'
 
setenv bootargs 'ignore_loglevel rw root=/dev/nfs nfsroot=192.168.1.2:/nfs/h3ulcb,nfsvers=3 ip=192.168.1.3:192.168.1.2::255.255.255.0:h3ulcb'
 
saveenv
 
</pre>
 
You can also use
 
<pre>
 
dhcp
 
</pre>
 
command to obtain information from DHCP server.<br/>
 
'''Note:''' You can always see the environment with ''printenv'' command.  Refer to [http://www.denx.de/wiki/U-Boot/Documentation U-Boot manual] for details.
 
</li>
 
 
 
<li>
 
Verify the connection over Ethernet from U-Boot:
 
<pre>
 
ping <your-computer-ip>
 
</pre>
 
You should see:
 
<pre>
 
=> ping 192.168.1.2   
 
ravb:0 is connected to ravb.  Reconnecting to ravb
 
ravb Waiting for PHY auto negotiation to complete.. done
 
ravb: 100Base/Full
 
Using ravb device
 
host 192.168.1.2 is alive
 
</pre>
 
</li>
 
 
 
<li>
 
Reset the board by pushing reset button
 
<br/>
 
Refer to [[R-Car/Boards/H3SK#Power_on_the_board_and_go_to_U-Boot_prompt|H3SK board page]], [[R-Car/Boards/M3SK#Power_on_the_board_and_go_to_U-Boot_prompt|M3SK board page]], [[R-Car/Boards/Salvator-X#Power_on_the_board_and_go_to_U-Boot_prompt|Salvator-X board page]] for more information.

==OpenCL support==
 
 
 
The following page describes how to enable OpenCL and Caffe support:
 
[[R-Car/Boards/Yocto-Gen3-legacy/OpenCL]]
 
 
 
==How to prepare and boot from eMMC/SD card==
 
 
 
This section describes steps that are necessary for preparing and booting from SD card.
 
 
 
===Preparing eMMC/SD card===
 
In order to prepare you SD card, follow these instructions on host machine:
 
 
 
1. Partion your SD card to set 1 partition and ID=83 (Linux)
 
<br/>
 
Make sure the SD card doesn't contain any important files.
 
<br/>
 
<span style="color:#ff0000">'''WARNING!''' These steps may erase the SD card completely. All files my be lost.</span>
 
 
 
$ fdisk /dev/mmcblk0
 
-> d
 
-> n
 
-> p
 
-> 1
 
-> t
 
-> 83
 
 
 
2. Format this partition to ext3 (or ext4)
 
 
 
$ mkfs.ext3 /dev/mmcblk0p1
 
 
 
3. Mount this partition on your host to any directory and upack the core-image-weston-*.tar.bz2 into mounted folder.
 
 
 
$ mount /dev/mmcblk0p1 /mnt
 
$ cd <your_yocto_build_directory>
 
$ tar xfj  build/tmp/deploy/images/h3ulcb/core-image-weston-h3ulcb-*.rootfs.tar.bz2  -C /mnt
 
 
 
NOTE: probably you need to be a root user, hence use "sudo"
 
 
 
===Configure U-Boot to boot from SD card===
 
 
 
Proper U-Boot command to boot from SD:
 
# setenv bootargs 'rw root=/dev/mmcblk1p1 rootfstype=ext3 rootwait'
 
# ext2load mmc 0:1 0x48080000 /boot/Image
 
# ext2load mmc 0:1 0x48000000 /boot/Image-r8a7795-h3ulcb.dtb
 
# booti 0x48080000 - 0x48000000'
 
 
 
Example of U-Boot environment variables:
 
baudrate=115200
 
bootargs_emmc=rw root=/dev/mmcblk0p1 rootfstype=ext3 rootwait
 
bootargs_nfs=rw root=/dev/nfs rootwait ip=dhcp
 
bootargs_sd0=rw root=/dev/mmcblk1p1 rootfstype=ext3 rootwait
 
bootcmd=run bootcmd_sd0
 
bootcmd_emmc=set bootargs ${bootargs_emmc};ext2load mmc 1:1 0x48080000 /boot/Image;ext2load mmc 1:1 0x48000000 /boot/${dtb};run booti_cmd
 
bootcmd_nfs=set bootargs ${bootargs_nfs};bootp 0x48080000 Image;tftp 0x48000000 ${dtb};run booti_cmd
 
bootcmd_sd0=set bootargs ${bootargs_sd0};ext2load mmc 0:1 0x48080000 /boot/Image;ext2load mmc 0:1 0x48000000 /boot/${dtb};run booti_cmd
 
bootdelay=3

To verify the SD card, type the following in U-Boot prompt:
 
=> mmc dev 0
 
switch to partitions #0, OK
 
mmc0 is current device
