\begin{frame}[fragile]
\frametitle{create an own layer for your BSP}
this layer typical includes
\begin{itemize}
\item machine configuration
\item kernel
\item bootloader
\item wic configuration
\item other hw specific recipes, or append files
\end{itemize}
\end{frame}
\begin{frame}[fragile]
\frametitle{yocto-bsp create}
the yocto-bsp command can be used to get a template:
\begin{verbatim}
poky % yocto-bsp create wega arm
poky % cd meta-wega
\end{verbatim}
The following files need to be available inside the layer:
\begin{verbatim}
recipes-kernel/linux-phytec/linux-phytec_4.4.52.bb
recipes-kernel/linux-phytec/files/wega/defconfig
recipes-bsp/barebox/barebox_2017.03.bb
recipes-bsp/barebox/files/wega/defconfig-ipl
recipes-bsp/barebox/files/wega/defconfig
scripts/lib/wic/canned-wks/am335x-sdimage.wks
conf/machine/wega.conf
conf/layer.conf
\end{verbatim}
\end{frame}
\begin{frame}[fragile]
\frametitle{create an own layer for your sw distro}
this layer typical includes
\begin{itemize}
\item distro configuration
\item own applications
\item append files to customize standard sw from other layers
\item own classes
\end{itemize}
e.g. to create meta-foo use:
\begin{verbatim}
poky % yocto-layer create foo
\end{verbatim}
\end{frame}
\begin{frame}[fragile]
\frametitle{generate a new build environment}
\begin{verbatim}
poky % . oe-init-build-env build-wega
poky/build-wega %
\end{verbatim}
\end{frame}
\subsection{configure build environment}
\begin{frame}
\frametitle{overview}
builds are configured using two configuration files
\begin{itemize}
\item /home/devel/poky/build-ti/conf/bblayers.conf
\item /home/devel/poky/build-ti/conf/local.conf
\end{itemize}
\end{frame}
\begin{frame}[fragile]
\frametitle{bblayers.conf}
additional layers are added with absolute! path to the BBLAYERS variable
\begin{verbatim}
BBLAYERS ?= " \
/home/devel/poky/meta \
/home/devel/poky/meta-yocto \
/home/devel/poky/meta-yocto-bsp \
"
\end{verbatim}
\begin{verbatim}
% bitbake-layers show-layers
layer path priority
=====================================================================
meta /home/devel/poky/meta 5
meta-yocto /home/devel/poky/meta-yocto 5
meta-yocto-bsp /home/devel/poky/meta-yocto-bsp 5
\end{verbatim}
\end{frame}
\begin{frame}[fragile]
\frametitle{add ti and meta-mini layers}
modify the BBLAYERS variable in bblayers.conf
\begin{verbatim}
BBLAYERS ?= " \
/home/devel/poky/meta \
/home/devel/poky/meta-yocto \
/home/devel/poky/meta-wega \
/home/devel/poky/meta-foo \
"
\end{verbatim}
\begin{verbatim}
% bitbake-layers show-layers

=====================================================================
meta /home/devel/poky/meta 5
