Create folder for yocto

$ mkdir yocto
$ cd yocto
$ mkdir sources
$ cd sources

Pull yocto project

$ git clone git://git.yoctoproject.org/poky -b dunfell

Download Raspberry-pi meta data

git clone git://git.yoctoproject.org/meta-raspberrypi -b dunfell

Download mate data for open embedded

git clone https://git.openembedded.org/meta-openembedded -b dunfell

Run the oe-init-build-env

cd yocto
cd poky
source ./oe-init-build-env

Add the raspberrypi to local.conf

nano ./poky/build/conf/local.conf

find the MACHINE line and change to the raspberrypi

MACHINE ??= “raspberrypi”

change bblayers.conf mine is looking like this

under the ./poky/build/conf/bblayers.conf directory

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = “2”

BBPATH = “${TOPDIR}”
BBFILES ?= “”

BBLAYERS ?= ” \

start compilation

bitbake core-image-minimal

after the successful

bzip2 -d -f tmp/deploy/images/raspberrypi/core-image-sato-raspberrypi.wic.bz2

You can burn the .wic file like this

sudo dd bs=4M if=core-image-minimal-raspberrypi.wic of=/dev/sdd conv=fsync

You can find the device

sudo fdisk -l

This is mine

if you want to add apt commant to the image open the local.conf and add there lines

CORE_IMAGE_EXTRA_INSTALL += "apt"

EXTRA_IMAGE_FEATURES ?= “package-management”

and then

bitbake rpi-basic-image
