Transcript: from git checkout to meta-intel BSP
From Yocto Project
Jump to navigationJump to search
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$ ls 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 Fetching yocto remote: Counting objects: 133191, done. remote: Compressing objects: 100% (39275/39275), done. remote: Total 133191 (delta 92863), reused 130090 (delta 90408) Receiving objects: 100% (133191/133191), 75.25 MiB | 1004 KiB/s, done.

Switched to a new branch 'edison-cur'
Now check out the meta-intel repo into the top-level Yocto repo dir:
trz@elmorro:/usr/local/dev/Yocto$ mkdir meta-intel trz@elmorro:/usr/local/dev/Yocto$ cd meta-intel trz@elmorro:/usr/local/dev/Yocto/meta-intel$ git init Initialized empty Git repository in /usr/local/dev/Yocto/meta-intel/.git/ trz@elmorro:/usr/local/dev/Yocto/meta-intel$ git remote add meta-intel git://git.yoctoproject.org/meta-intel.git trz@elmorro:/usr/local/dev/Yocto/meta-intel$ git remote update Fetching meta-intel remote: Counting objects: 3042, done. remote: Compressing objects: 100% (2462/2462), done. remote: Total 3042 (delta 1522), reused 194 (delta 105) Receiving objects: 100% (3042/3042), 1.73 MiB | 531 KiB/s, done.

Switched to a new branch 'fishriver' trz@elmorro:/usr/local/dev/Yocto/meta-intel$ cd .. trz@elmorro:/usr/local/dev/Yocto$ source oe-init-build-env You had no conf/local.conf file. This configuration file has therefore been created for you with some default values. You may wish to edit it to use a different MACHINE (target hardware) or enable parallel build options to take advantage of multiple cores for example. See the file for more information as common configuration options are commented. The Yocto Project has extensive documentation about OE including a reference manual which can be found at: http://yoctoproject.org/documentation For more information about OpenEmbedded see their website: http://www.openembedded.org/ You had no conf/bblayers.conf file. The configuration file has been created for you with some default values. To add additional metadata layers into your configuration please add entries to this file. The Yocto Project has extensive documentation about OE including a reference manual which can be found at: http://yoctoproject.org/documentation For more information about OpenEmbedded see their website: http://www.openembedded.org/ ### 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/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$ cd /usr/local/dev/Yocto/
trz@elmorro:/usr/local/dev/Yocto$ source oe-init-build-env
### 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'
trz@elmorro:/usr/local/dev/Yocto/build$ bitbake core-image-sato

Now dd the 'live' image to a USB drive (/dev/sdf for me, yours will be different):
trz@elmorro:/usr/local/src/Yocto/build/tmp/deploy/images$ sudo dd if=poky-image-sato-live-fishriver-20110405031037.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/src/Yocto/build/tmp/deploy/images$ sync trz@elmorro:/usr/local/src/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
