How do I - Yocto Project
Q: How do I put Yocto on a hard drive?
A: bitbake core-image-sato or core-image-sato-sdk

have a suitable partition on the disk - say partition #3
this partition will show up as sde3 on my host machine and sda3 on the atom
mkfs.ext3 /dev/sde3
mount /dev/sde3 /mnt/target
mount -o loop tmp/deploy/images/core-image-sato-sdk.ext3 /mnt/target-ext3
cp -a /mnt/target-ext3/* /mnt/target
grub-install --recheck --root-directory=/mnt/target /dev/sde
If grub install passed, copy the following to...

Modifying the SD-Card Image / Adding new Layers - Entries - Forum - Industry Support - Siemens
Hi, 

at first you have to have a look at ªªhttp://layers.openembedded.org/layerindex/branch/master/recipes/ andºº search for your recipe (i.e apache). 

You will find the layer (i.e meta-webserver)  which includes the package. This layer you will have to clone to your build system. If you click on the layer you find the adress to clone and its dependencies. It may be that you will need to clone other layers additionally. 

In your case meta-webserver is already cloned, because it is inc...

linux - Difference between wic and hddimg format in yocto - Stack Overflow
There was not much info about online, so I asked this question in the intel community and here is the response of that: Generally a .wic image is intended to be installed directly to its final destination, whereas an hddimg is for evaluation and installation elsewhere. By default meta-intel .wic images only have an EFI bootloader, and will not boot via legacy BIOS. An hddimg will have both an EFI bootloader and the syslinux binaries that let it boot from legacy BIOS. On startup with your installer USB image do you get a light gray screen with four options? If so it is booting via legacy BIOS.

The Architecture of Open Source Applications (Volume 2): The Yocto Project
In 2001, Sharp Corporation introduced the SL-5000 PDA, named Zaurus, which ran an embedded Linux distribution, Lineo. Not long after the Zaurus's introduction, Chris Larson founded the OpenZaurus Project, a replacement Linux distribution for the SharpROM, based on a build system called buildroot. With the founding of the project, people began contributing many more software packages, as well as targets for other devices, and it wasn't long before the build system for OpenZaurus began to show fragility. In January 2003, the community began discussing a new build system to incorporate the community usage model of a generic build system for embedded Linux distributions. This would eventually become OpenEmbedded. Chris Larson, Michael Lauer, and Holger Schurig began work on OpenEmbedded by porting hundreds of OpenZaurus packages over to the new build system.

The Yocto Project springs from this work. At the project's core is the Poky build system, created by Richard Purdie. It began as a stabilized branch of OpenEmbedded using a core subset of the thousands of OpenEmbedded recipes, across a limited set of architectures. Over time, it slowly coalesced into more than just an embedded build system, but into a complete software development platform, with an Eclipse plugin, a fakeroot replacement and QEMU based images. Around November 2010, the Linux Foundation announced that this work would all continue under the heading of the Yocto Project as a Linux Foundation-sponsored project. It was then established that the Yocto Project and OpenEmbedded would coordinate on a core set of package metadata called OE-Core, combining the best of both Poky and OpenEmbedded with an increased use of layering for additional components.
