To build and run a meta-intel BSP, you need to check out a local copy of the poky repo, along with a local copy of the meta-intel repo somewhere inside the poky checkout e.g. see below (the example below uses the 'fishriver' BSP as an example. For other meta-intel BSPs, you can use the instructions in the same way - just substitute the BSP name you actually want to build below e.g. for the jasperforest BSP, substitute 'jasperforest', 'meta-jasperforest', etc.

NOTE: this transcript was from a build done on a Ubuntu 10.04 system. Please see the 'Yocto Project Quickstart' for the packages required to be installed on the host system for building [1]

First do the basic checkout of the Yocto sources: 

trz@elmorro:/usr/local/dev$ mkdir Yocto
trz@elmorro:/usr/local/dev$ cd Yocto/
trz@elmorro:/usr/local/dev/Yocto$ git init
Initialized empty Git repository in /usr/local/dev/Yocto/.git/
trz@elmorro:/usr/local/dev/Yocto$ git remote add yocto git://git.yoctoproject.org/poky.git
trz@elmorro:/usr/local/dev/Yocto$ git remote update

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
    core-image-sato
    meta-toolchain
    meta-toolchain-sdk
    adt-installer
    meta-ide-support

You can also run generated qemu images with a command like 'runqemu qemux86'


Before building, you need to add the meta-fishriver layer so the build recognizes it. So edit bblayers.conf: 

trz@elmorro:/usr/local/dev/Yocto/build$ emacs -nw conf/bblayers.conf

And change: 

BBLAYERS = " \                                                                                                       
  /usr/local/dev/Yocto/meta \                                                                                        
  /usr/local/dev/Yocto/meta-yocto \                                                                                  
  "

to: 

BBLAYERS = " \                                                                                                       
  /usr/local/dev/Yocto/meta \                                                                                        
  /usr/local/dev/Yocto/meta-yocto \                                                                                  
  /usr/local/dev/Yocto/meta-intel \
  /usr/local/dev/Yocto/meta-intel/meta-fishriver \                                                                   
  "

You also need to make a few changes to your local.conf: 

trz@elmorro:/usr/local/dev/Yocto/build$ emacs -nw conf/local.conf

Change: 

MACHINE ??= "qemux86"

to 

MACHINE ??= "fishriver"

To make the build go faster, depending on how many CPUs you have change the following variables. I have 4 cores, with HT, so I'm changing my values to 8: 

trz@elmorro:/usr/local/dev/Yocto/build/conf$ emacs -nw local.conf
BB_NUMBER_THREADS = "8"
PARALLEL_MAKE = "-j 8"

Since this is your first build, it won't matter - it will take awhile regardless, but for later builds, to avoid re-downloading all the packages again, you can point the DL_DIR variable in local conf to the downloads dir of a previous build.

You're now ready to build your image, which make take several hours. Continuing the session...: 

trz@elmorro:/usr/local/dev/Yocto/build/conf$ cd /usr/local/dev/Yocto
trz@elmorro:/usr/local/dev/Yocto$ source oe-init-build-env 

### Shell environment set up for builds. ###

    core-image-sato

    meta-ide-support

You can also run generated qemu images with a command like 'runqemu qemux86'

The build succeeded - look in build/tmp/deploy/images for the bootable image:

Now dd the 'live' image to a USB drive (/dev/sdf for me, yours will be different): 

trz@elmorro:/usr/local/dev/Yocto/build/tmp/deploy/images$ sudo dd if=core-image-sato-fishriver-20120305152905.hddimg of=/dev/sdf
[sudo] password for trz: 
1136664+0 records in
1136664+0 records out
581971968 bytes (582 MB) copied, 5.15645 s, 113 MB/s
trz@elmorro:/usr/local/dev/Yocto/build/tmp/deploy/images$ sync
trz@elmorro:/usr/local/dev/Yocto/build/tmp/deploy/images$ eject /dev/sdf

The image should now be on the USB drive and ready to boot, enjoy!

NOTE: if you have a problem with e.g. garbage characters, or other strange things, try doing this before you dd the image: 

$ sudo dd if=/dev/zero of=/dev/sdf bs=1M count=1024
