Yocto Project: quickest instructions to generate BeagleBone images

Here are the quickest instructions (I hope) for having the Yocto Project build an embedded Linux image for BeagleBone boards based on the TI AM335x CPU:

git clone -b kirkstone https://git.yoctoproject.org/git/poky
source poky/oe-init-build-env

This gets you in a new build directory. You can then generate your image:

MACHINE="beaglebone-yocto" bitbake core-image-minimal

Once the build is over, you can flash the image on a microSD card (assuming it’s mapped to /dev/mmcblk0):

cd tmp/deploy/images/beaglebone-yocto
dd if=core-image-minimal-beaglebone-yocto.wic of=/dev/mmcblk0 bs=4M

More details for customizing images and supporting other boards in the Yocto Project manual.
