This guide shows a step-by-step on how to build Yocto image using Intel BSP guide.

Detail documentation PDF can be found here

Pre-requisites

Before you start, make sure that you have fulfill all these requirements:

• A Linux PC host (we use Ubuntu 12.04).
• A stable network connection.

Install some dependencies:

$ sudo apt-get install build-essential git diffstat texinfo gawk chrpath file git-core coreutils unziplibsdl1.2-dev desktop-file-utils autoconf automake libtools p7zip-full

1. Get Quark BSP (1.0.1) package

Download an official Quark BSP (1.0.1) package from Intel page:

[http://downloadmirror.intel.com/23197/eng/Board_Support_Package_Sources_for_Intel_Quark_v1.0.1.7z]

2. Prepare BSP Patches

Download BSP Patches and Build Instruction package: [http://downloadmirror.intel.com/24355/eng/BSP-Patches-and-Build_Instructions.1.0.4.tar.bz2]

Untar the package:

$ tar -xvjf BSP-Patches-and-Build_Instructions.1.0.4.tar.bz2

3. Prepare meta-clanton

Unpack BSP package:

$ 7z x Board_Support_Package_*.7z

Unpack meta-clanton

$ tar xzvf meta-clanton_v1.0.1.tar.gz

4. Run setup.sh

Go into meta-clanton directory and run setup:

$ cd meta-clanton_v1.0.1/
$ ./setup.sh

5. Apply Patches

Apply some patches in recipes. Just copy-paste the commands into terminal and execute.

$ echo 'SRC_URI += "file://4.MAKER-222-Sketch_download_unstable-5.patch"' >> meta-clanton-distro/recipes-galileo/galileo-target/galileo-target_0.1.bb

6. Resize Image

For this purpose of image, increase the size of image (from 300Mb into 3GB) in order to give more spaces for the image.

Open image-full.bb file in /meta-clanton_v1.0.1/meta-clanton-distro/recipe-core/images/ directory, then edit this line:

IMAGE_ROOTFS_SIZE = "3072000"

7. Build the Image

Execute this commands:

$ source poky/oe-init-build-env yocto_build/

$ bitbake image-full-galileo

*Building the image may take times to complete.

Upon successful build, you may see something shown below:

If build failed, trace the errors which may lead for re-build. Example of failed build is shown below:

8. Prepare Micro-SD Card

Go to meta-clanton_v1.0.1/yocto_build/tmp/deploy/images/ directory and copy these items into SD card:

• boot directory
• bootia32.efi
• bzImage-3.8.r0-clanton-*.bin
• core-image-minimal-initramfs-clanton-*.cpio.gz
• grub.efi
• image-full-galileo-clanton-*.ext3

And finally rename these files:

• bzImage-3.8.r0-clanton-*.bin into bzImage
• core-image-minimal-initramfs-clanton-*.cpio.gz into core-image-minimal-clanton.cpio.gz
• image-full-galileo-clanton-*.ext3 into image-full-clanton.ext3

Put SD card into SD slot in Galileo board and boot your image.
