+\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
