Yocto/GettingStarted
Getting Started
This page is supposed to give a simple to follow guide of the first steps one have to do to assemble a setup for embedded development, preparing a first build via Yocto, build it and test-run it on the development device.
Material Needed
Embedded development always have the problem that you need some material additional to a development computer.
The most important components that one always should have:
- development board
- power supply for the development board
- micro SD card as main storage of the development board
- a micro SD card writer/reader
- a RS232-USB adapter for low level debugging of startup problems of the development board
Preparation for Yocto Build
Here we do a few things:
- Prepare a Docker container with the required Yocto dependencies, in which the Yocto build will happen.
- Checkout a configuration of the KDE Demo image and set it up
Preparation of Docker Container
The basic source code repository for this step is `kde:packaging/yocto-manifest` (https://invent.kde.org/packaging/yocto-manifest). Select a location where you have a lot (and this really means >200 GB) of free space. In the following, we assume that `/opt/yocto` is such a location; just replace it in the commands if it is different.
# get Yocto sources
export YOCTODIR=/opt/yocto
git clone kde:packaging/yocto-manifest manifest
# step: prepare docker container with name "yocto-kirkstone"
docker build ${YOCTODIR}/manifest/containers/kirkstone -t yocto-kirkstone
# step: obtain Google's repo tool
curl https://storage.googleapis.com/git-repo-downloads/repo > ${YOCTODIR}/repo
chmod a+x ${YOCTODIR}/repo
# step: prepare Yocto folder structure; using Yocto release "mickledore"
mkdir ${YOCTODIR}/mickledore && cd ${YOCTODIR}/mickledore
${YOCTODIR}/repo init -u https://invent.kde.org/packaging/yocto-manifest.git -m mickledore.xml
${YOCTODIR}/repo sync
