 Create a directory and switch to it Warning! Yocto builds require a lot of disk space (up to 100 GB). Make sure you have got enough before starting the build. mkdir build cd build export WORK=`pwd`  Clone basic Yocto layers: cd $WORK git clone git://git.yoctoproject.org/poky git clone git://git.openembedded.org/meta-openembedded git clone git://git.linaro.org/openembedded/meta-linaro.git 

 Switch to proper branches/commits   For Yocto v2.12.0 cd $WORK/poky git checkout -b tmp 40376446904ae3529be41737fed9a0b650ed167d cd $WORK/meta-openembedded git checkout -b tmp 8ab04afbffb4bc5184cfe0655049de6f44269990 cd $WORK/meta-linaro git checkout -b tmp 9b1fd178309544dff1f7453e796a9437125bc0d9   Another versions are not tested for compatibility. </li>

 Edit $WORK/build/conf/local.conf to enable/disable graphics and multimedia proprietary drivers support </li>

 Edit local.conf to choose machine extension variant </li>

For H3ULCB board only:

  Edit local.conf to select IO configuration (by default only H3ULCB board peripherals are enabled): MACHINE_FEATURES_append = " h3ulcb-view" (use this append for View IO configuration) or MACHINE_FEATURES_append = " h3ulcb-had" (use this append for HAD IO configuration) </li> </ol>

Running Yocto image
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: sudo apt-get install tftp tftpd-hpa

Fedora
<ol> <li> Install necessary packages: sudo yum install tftp-server tftp tftp-server is a part of xinetd. See Fedora manual for more information. </li> <li> Enable TFTP server: sudo vi /etc/xinetd.d/tftp Set disable = no Save file and exit. </li> <li> Start xinetd: sudo systemctl start xinetd.service sudo systemctl enable xinetd.service </li> </ol>

</li>

<li> Copy uImage and uImage-r8a7794-silk.dtb from $WORK/build/tmp/deploy/images/silk/ to TFTP server root.

Ubuntu
cp $WORK/build/tmp/deploy/images/silk/uImage /srv/tftp/ cp $WORK/build/tmp/deploy/images/silk/uImage-r8a7794-silk.dtb /srv/tftp/

Fedora
cp $WORK/build/tmp/deploy/images/silk/uImage /var/lib/tftpboot/ cp $WORK/build/tmp/deploy/images/silk/uImage-r8a7794-silk.dtb /var/lib/tftpboot/ </li>

<li> Verify that TFTP server is working. tftp localhost -c get uImage && ls uImage </li>

<li> Setup NFS server.

Debian/Ubuntu
<ol> <li> Install necessary packages: sudo apt-get install nfs-kernel-server nfs-common </li> <li> Start NFS server: sudo /etc/init.d/nfs-kernel-server start </li> </ol>

Fedora
<ol> <li> Install necessary packages: sudo yum install nfs-utils </li> <li> Enable and start nfs server: 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 </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: IMAGE=weston|x11|sato|directfb MACHINE=silk|porter 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 </li> <li> Edit /etc/exports: sudo vi /etc/exports add /nfs/silk	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash) /nfs/porter	*(rw,no_subtree_check,sync,no_root_squash,no_all_squash) Save the file and exit. </li> <li> Force NFS server to re-read /etc/exports sudo exportfs -a </li> </ol> </li> <li> Verify that NFS is working. [builduser@buildmachine ~]$ showmount -e localhost Export list for localhost: /nfs/silk * /nfs/porter * </li>

<li> Boot into U-Boot command prompt

For SILK board
<ol> <li> Make sure SW9 is on pin 1 side. </li> <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 SILK board page for more information.

For Porter board
<ol> <li> TBD </li> </ol> NOTE: Stout board does not have extra switches to select boot device (e.g. primary and secondary/backup QSPI Flash)

</li>

<li> Configure Ethernet, TFTP, and kernel command line in U-Boot:

Loading kernel and rootfs from microSD card
Both kernel and root FS can be loaded from a microSD card. The approach requires only a console cable. No Ethernet connection is needed. <ol> <li> Find a reliable microSD card with an adapter to fit your computer. 4 GB should be enough for the task. </li>

<li> Plug the SD card into you computer. Locate the proper device for it, typically /dev/mmcblk0. Use dmesg | tail to print latest messages if in doubt. WARNING! Be very careful. Do not select you root partition or any other device with important information. It may be destroyed! Double-check that device name is correct by mounting and examining it's content. </li>

<li> Make sure the SD card doesn't contain any important files. WARNING! Next step may erase the SD card completely. All files my be lost. </li>

<li> Format the card with one partition with EXT3 file system. TBD Update this page with a script which formats the card </li>

<li> Copy root fs to the sd card: SD=<path-to-your-device-partition> SD_ROOT=/tmp/sd-tool sudo umount "${SD}" sudo mkdir -p "${SD_ROOT}" sudo mount "${SD}" "${SD_ROOT}" sudo rm -rf "${SD_ROOT}"/* sudo cp "${BUILDDIR}/tmp/deploy/images/${MACHINE}/uImage+dtb" "${SD_ROOT}/boot/" sudo tar -xjf "${BUILDDIR}/tmp/deploy/images/${MACHINE}/core-image-${IMAGE}-${MACHINE}.tar.bz2" -C "${SD_ROOT}" sudo umount "${SD}" </li>

<li> Insert the SD card into microSD slot on the board. </li>

<li> Boot the board into U-Boot command prompt. Refer to section Boot into U-Boot command prompt </li>

Multiboot
U-Boot allows multiboot configurations. U-Boot can try different boot commands one by one until find the first working command. Use command line interface to configure u-boot. Dual source (MMC and NFS) boot configuration for Silk: setenv mkBootcmdMMC 'setenv bootcmd ext4load mmc 1:1 0x40007fc0 /boot/uImage+dtb\; bootm 0x40007fc0' setenv mkBootargsMMC 'setenv bootargs console=ttySC10,38400 ignore_loglevel rw rootfstype=ext3 root=/dev/mmcblk0p1 rootwait vmalloc=384M' setenv mkBootcmdTFTP 'setenv bootcmd tftp 0x40007fc0 uImage+dtb.silk\; bootm 0x40007fc0' setenv mkBootargsNFS 'setenv bootargs console=ttySC10,38400 ignore_loglevel rw root=/dev/nfs nfsroot=192.168.1.27:/nfs/silk,nfsvers=3 ip=192.168.1.107:192.168.1.27::255.255.255.0:silk vmalloc=384M' setenv bootMMC 'run mkBootargsMMC; run mkBootcmdMMC; run bootcmd' setenv bootNET 'run mkBootargsNFS; run mkBootcmdTFTP; run bootcmd' setenv bootcmd 'run bootMMC; run bootNET' For Porter and Stout mkBootcmdMMC, mkBootargsMMC, mkBootcmdTFTP and mkBootargsNFS should be correctly changed according to their bootcmds and bootargs </ol>

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:

1.Partion your SD card to set 1 partition and ID=83 (Linux)

$ 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-XXXX.tar.bz2 into mounted folder.

$ mount /dev/mmcblk0p1 /mnt $ cd <your_yocto_build_directory> $ tar xfj build/tmp/deploy/images/salvator-x/core-image-weston-salvator-x-20160927181256.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:
 * 1) setenv bootargs 'rw root=/dev/mmcblk1p1 rootfstype=ext3 rootwait'
 * 2) ext2load mmc 0:1 0x48080000 /boot/Image
 * 3) ext2load mmc 0:1 0x48000000 /boot/Image-r8a7795-salvator-x.dtb
 * 4) booti 0x48080000 - 0x48000000'
